feat(setup-gbrain): carve the branch-exclusive install paths into sections
Brain-init (Paths 1/2/3/4 bodies), engine remediation, transcript gate, and CLAUDE.md persist load on demand — at most one install route ever runs. Skeleton 75.3KB -> 57.0KB; the Step 1 detect and Step 2 path dispatch stay always-loaded. New buildSetupGbrainFixture helper gives the periodic E2Es extract-don't-copy fixtures with a non-empty guard; the voyage-code-3 gate counts scan the tmpl union (the third init site lives in engine-remediation).

This skill is a decision-tree skeleton. The steps below point to on-demand

2b, 3, 4 (4a-4e), and the Switch migration flow — lives in the brain-init
|
||||
section. Run ONLY the sub-section for the picked path.
|
||||
|
||||
### Path 1 (Supabase, existing URL)
|
||||
|
||||
Source the secret-read helper, collect URL with `read -s` + redacted preview:
|
||||
|
||||
```bash
|
||||
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
|
||||
read_secret_to_env GBRAIN_POOLER_URL "Paste Session Pooler URL: " \
|
||||
--echo-redacted 's#://[^@]*@#://***@#'
|
||||
```
|
||||
|

Then validate structurally:

|
||||
```bash
|
||||
printf '%s' "$GBRAIN_POOLER_URL" | ~/.claude/skills/gstack/bin/gstack-gbrain-supabase-verify -
|
||||
```
|
||||
|
||||
If the verify exit code is 3 (direct-connection URL), the verifier's own
|
||||
message explains the fix; surface it and re-prompt for a Session Pooler URL.
|
||||
|
||||
On success, hand off to gbrain via env var (D10, never argv):
|
||||
|
||||
```bash
|
||||
GBRAIN_DATABASE_URL="$GBRAIN_POOLER_URL" gbrain init --non-interactive --json
|
||||
```
|
||||
|
||||
Then `unset GBRAIN_POOLER_URL GBRAIN_DATABASE_URL` immediately. The URL is
|
||||
now persisted in `~/.gbrain/config.json` at mode 0600 by gbrain itself.
|
||||
|
||||
### Path 2a (Supabase, auto-provision — D7)
|
||||
|
||||
Show the D11 PAT scope disclosure verbatim BEFORE collecting the token:
|
||||
|
||||
> *This Supabase Personal Access Token grants full read/write/delete access
|
||||
> to every project in your Supabase account, not just the `gbrain` one we're

|
||||
> this PAT only to: create one project, poll it until healthy, read the
|
||||
> Session Pooler URL — then discard it from process memory. The token
|
||||
> remains valid on Supabase's side until you manually revoke it at
|
||||
> https://supabase.com/dashboard/account/tokens — we recommend revoking
|
||||
> immediately after setup completes.*
|
||||
|
||||
Then:
|
||||
|
||||
```bash
|
||||
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
|
||||
read_secret_to_env SUPABASE_ACCESS_TOKEN "Paste PAT: "
|
||||
```
|
||||
|
||||
Ask the D17 tier prompt via AskUserQuestion: "Which Supabase tier?" Present
|
||||
Free (2-project limit, pauses after 7d inactivity) vs Pro ($25/mo, no
|
||||
pauses, recommended for real use). Explain that tier is **org-level** (per
|
||||
the Management API contract) — user picks their org based on its current
|
||||
tier. Pro may require them to upgrade the org first at supabase.com.
|
||||
|
||||
List orgs, pick one (AskUserQuestion if multiple):
|
||||
|
||||
```bash
|
||||
orgs=$(~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision list-orgs --json)
|
||||
```
|
||||
|
||||
If the `.orgs` array is empty, surface: "Your Supabase account has no
|
||||
organizations. Create one at https://supabase.com/dashboard, then re-run
|
||||
`/setup-gbrain`." STOP.
|
||||
|
||||
Ask the user for a region (default `us-east-1`; valid values are the 18
|
||||
enum values in the Supabase Management API — list a few common ones, let
|
||||
them pick "Other" for a full list).
|
||||
|
||||
Generate the DB password (never shown to the user):
|
||||
|
||||
```bash
|
||||
export DB_PASS=$(openssl rand -base64 24)
|
||||
```
|
||||
|
||||
Set up a SIGINT trap (D12 basic recovery):
|
||||
|
||||
```bash
|
||||
trap 'echo ""; echo "gstack-gbrain: interrupted. In-flight ref: $INFLIGHT_REF"; \
|
||||
echo "Resume: /setup-gbrain --resume-provision $INFLIGHT_REF"; \
|
||||
echo "Delete: https://supabase.com/dashboard/project/$INFLIGHT_REF"; \
|
||||
unset SUPABASE_ACCESS_TOKEN DB_PASS; exit 130' INT TERM
|
||||
```
|
||||
|
||||
Create + wait + fetch:
|
||||
|
||||
```bash
|
||||
result=$(~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision \
|
||||
create gbrain "$REGION" "$ORG_SLUG" --json)
|
||||

|
||||

||||

||||

|
||||
unset SUPABASE_ACCESS_TOKEN DB_PASS GBRAIN_DATABASE_URL INFLIGHT_REF
|
||||
trap - INT TERM
|
||||
```
|
||||
|
||||
After success, emit the PAT revocation reminder:
|
||||
|
||||
> "Setup complete. Revoke the PAT you pasted at
|
||||
> https://supabase.com/dashboard/account/tokens — we've already discarded
|
||||
> it from memory and don't need it again. The gbrain project will continue
|
||||
> working because it uses its own embedded database password."
|
||||
|
||||
### Path 2b (Supabase, manual)
|
||||
|
||||
Walk the user through the supabase.com steps:
|
||||
1. Login at https://supabase.com/dashboard
|
||||
2. Click "New Project," name it `gbrain`, pick a region, copy the generated
|
||||
database password (you'll need it for paste-back? no — it's embedded in
|
||||
the pooler URL we collect next)
|
||||
3. Wait ~2 min for the project to initialize
|
||||
4. Settings → Database → Connection Pooler → Session → copy the URL (port
|
||||
6543)
|
||||
|
||||
Then follow the same secret-read + verify + init flow as Path 1.
|
||||
|
||||
### Path 3 (PGLite local)
|
||||
|
||||
```bash
|
||||
# gstack default: voyage-code-3 (1024d) when VOYAGE_API_KEY is set — code
|
||||
# retrieval beats general-purpose embeddings on real code queries (validated
|
||||
# A/B). Without the key, gbrain auto-selects (OpenAI 1536d when available).
|
||||
# Never select gbrain's legacy zeroentropyai recipe for a new brain: the hosted
|
||||
# API sunsets September 4, 2026 (#2365); the wireup helper warns existing installs.
|
||||
set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)
|
||||
if [ -n "${VOYAGE_API_KEY:-}" ]; then
|
||||
set -- --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024
|
||||
fi
|
||||
gbrain init --pglite --json "$@"
|
||||
```
|
||||
|
||||
Done. No network, no secrets (beyond Voyage embedding API calls during sync, if
|
||||
`VOYAGE_API_KEY` is set — ~$0.18 per 1M tokens, pennies per repo).
|
||||
|
||||
### Path 4 (Remote gbrain MCP — HTTP transport with bearer token)
|
||||
|
||||
For users whose brain runs on another machine (Tailscale, ngrok, internal
|
||||
LAN, or a teammate's server). No local gbrain CLI install, no local DB.
|
||||
This skill registers the remote MCP and stops; ingestion + indexing happens
|
||||
on the brain host.
|
||||
|
||||
**4a. Collect MCP URL.** Prompt the user:
|
||||
|
||||
```
|
||||
Paste your gbrain MCP URL (e.g. https://wintermute.tail554574.ts.net:3131/mcp):
|
||||
```
|
||||
|
||||
Read with plain `read -r` (no secret hygiene needed — the URL alone isn't
|
||||
a credential). Validate it starts with `https://` (require TLS for any
|
||||
non-loopback host); refuse `http://` for non-localhost.
|
||||
|
||||
**4b. Collect bearer token via the secret-read helper (D10, never argv).**
|
||||
|
||||
```bash
|
||||
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
|
||||
read_secret_to_env GBRAIN_MCP_TOKEN "Paste bearer token: " \
|
||||
--echo-redacted 's/.\{6\}$/***REDACTED***/'
|
||||
```
|
||||
|
||||
**4c. Verify via gstack-gbrain-mcp-verify.** Run the helper; capture the
|
||||
classified JSON output:
|
||||
|
||||
```bash
|
||||
verify_json=$(GBRAIN_MCP_TOKEN="$GBRAIN_MCP_TOKEN" \
|
||||
~/.claude/skills/gstack/bin/gstack-gbrain-mcp-verify "$MCP_URL")
|
||||
status=$(echo "$verify_json" | jq -r .status)
|
||||
```
|
||||
|
||||
If `status != "success"`, the helper has already classified the failure
|
||||
into NETWORK / AUTH / MALFORMED and emitted a one-line remediation hint.
|
||||
Surface the hint above the raw error from `error_text` and **STOP** with
|
||||
a clear "fix and re-run /setup-gbrain" message. Do NOT continue to Step 5a
|
||||
on a failed verify — partial registration would leave the user with a
|
||||
half-broken state.
|
||||
|
||||
Capture two values from the verify output for downstream steps:
|
||||
- `SERVER_VERSION` (e.g., `0.27.1`) — written to the CLAUDE.md block in Step 8.
|
||||
- `URL_FORM_SUPPORTED` (`true|false`) — passed to `gstack-artifacts-init` in
|
||||
Step 7 to control which form of the brain-admin hookup command is printed.
|
||||
|
||||
**4d. (Path 4) Offer local PGLite for code search.** Per plan D10/D11, ask:
|
||||
|
||||
> D# — Want symbol-aware code search on this machine?
|
||||
> Project/branch/task: <one-sentence grounding using detected slug + branch>
|
||||
> ELI10: The remote brain at `<MCP_URL>` is great for cross-machine knowledge,
|
||||
> but symbol queries like `gbrain code-def` / `code-refs` / `code-callers` need
|
||||
> a local index of THIS machine's code. We can spin up a tiny isolated PGLite
|
||||
> database (~30 seconds, no accounts, ~120 MB disk) just for code, separate
|
||||
> from your remote brain. Transcripts and artifacts continue routing through
|
||||
> the artifacts repo to the remote brain — local PGLite stays code-only.
|
||||
> Stakes: without it, semantic code search in this repo's worktrees falls
|
||||
> back to Grep.
|
||||
> Recommendation: A — 30 seconds, no ongoing cost, unlocks the symbol tools.
|
||||
> Completeness: A=10/10 (full split-engine), B=7/10 (remote-only).
|
||||
> A) Yes, set up local PGLite for code (recommended)
|
||||
> ✅ Unlocks `gbrain code-def`, `code-refs`, `code-callers` per worktree
|
||||
> ✅ Independent engine — won't disturb remote brain or share transcripts
|
||||
> B) No, remote MCP only
|
||||
> ✅ Zero local state — only `~/.claude.json` MCP registration
|
||||
> ❌ Symbol code queries fall back to Grep in this repo's worktrees
|
||||
> Net: A = full split-engine; B = remote-only.
|
||||
|
||||
**If A (Yes)**: install + init local PGLite with rollback-safe semantics (D7):
|
||||
|
||||
```bash
|
||||
~/.claude/skills/gstack/bin/gstack-gbrain-install || exit $?
|
||||
# At this point the local gbrain CLI is on PATH. Init PGLite, but back up any
|
||||
# existing ~/.gbrain/config.json first (rollback if init fails).
|
||||
if [ -f "$HOME/.gbrain/config.json" ]; then
|
||||
BACKUP="$HOME/.gbrain/config.json.gstack-bak-$(date +%s)"
|
||||
mv "$HOME/.gbrain/config.json" "$BACKUP"
|
||||
fi
|
||||
# gstack default for local code-search PGLite: voyage-code-3 (1024d) when
|
||||
# VOYAGE_API_KEY is set. It wins the A/B over voyage-4-large and OpenAI
|
||||
# text-embedding-3-large on this codebase's symbol queries. Falls back to
|
||||
# gbrain's auto-selected provider when the key isn't present.
|
||||
set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)
|
||||
if [ -n "${VOYAGE_API_KEY:-}" ]; then
|
||||
set -- --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024
|
||||
fi
|
||||
if ! gbrain init --pglite --json "$@"; then
|
||||
if [ -n "${BACKUP:-}" ] && [ -f "$BACKUP" ]; then mv "$BACKUP" "$HOME/.gbrain/config.json"; fi
|
||||
echo "gbrain init failed. Existing config (if any) was restored. PGLite at ~/.gbrain/pglite/ may be in a partial state — \`rm -rf ~/.gbrain/pglite\` to reset." >&2
|
||||
echo "Continuing setup without local code search; you can re-run /setup-gbrain to retry." >&2
|
||||
fi
|
||||
```
|
||||
|
||||
Then continue to Step 5a. The remote-http MCP registration in 5a runs as
|
||||
today; the local PGLite is independent of MCP registration (Claude Code talks
|
||||
to the remote brain via MCP for queries; `gbrain` CLI talks to local PGLite
|
||||
for code-def/refs/callers).
|
||||
|
||||
**If B (No)**: skip the install + init. The local engine stays absent.
|
||||
`gbrain_local_status` will be `missing-config` (or `no-cli` if gbrain isn't
|
||||
installed). `/sync-gbrain` will SKIP the code stage cleanly per plan D12.
|
||||
|
||||
**4e. Skip Steps 3, 4 (other paths) and 5 (local doctor) when B was picked.**
|
||||
When A was picked, Step 3 already ran (via gstack-gbrain-install) and Step 4
|
||||
already ran (via `gbrain init --pglite`); jump straight to Step 5a. When B
|
||||
was picked, Steps 3/4/5 are no-ops; also skip Step 7.5 (transcript ingest)
|
||||
since memory-stage routes through the artifacts pipeline in remote-http mode
|
||||
per plan D11.
|
||||
|
||||
The bearer token (`GBRAIN_MCP_TOKEN`) stays in process env until Step 5a's

## Step 8: Persist `## GBrain Configuration` in CLAUDE.md
|
||||
|
||||
Find-and-replace (or append) the section. Block format depends on mode:
|
||||
CLAUDE.md is the audit trail: after a successful setup, persist the
|
||||
configuration block. The exact block formats (remote-http vs local-stdio) and
|
||||
the post-Step-9 Search Guidance write live in the claude-md-persist section.
|
||||
|
||||
### Path 4 (Remote MCP)
|
||||
|
||||
```markdown
|
||||
## GBrain Configuration (configured by /setup-gbrain)
|
||||
- Mode: remote-http
|
||||
- MCP URL: {MCP_URL}
|
||||
- Server version: gbrain v{SERVER_VERSION} (from Step 4c verify)
|
||||
- Setup date: {today}
|
||||
- MCP registered: yes (user scope)
|
||||
- Token: stored in ~/.claude.json (do not commit; never written to CLAUDE.md)
|
||||
- Artifacts repo: {gstack_artifacts_remote URL or "none"}
|
||||
- Artifacts sync: {off|artifacts-only|full}
|
||||
- Current repo policy: {read-write|read-only|deny|unset}
|
||||
```
|
||||
|
||||
The bearer token is **never** written to CLAUDE.md (CLAUDE.md is checked
|
||||
in to git in many projects). It lives only in `~/.claude.json` where
|
||||
`claude mcp add` placed it.
|
||||
|
||||
### Paths 1, 2a, 2b, 3 (Local stdio)
|
||||
|
||||
```markdown
|
||||
## GBrain Configuration (configured by /setup-gbrain)
|
||||
- Mode: local-stdio
|
||||
- Engine: {pglite|postgres}
|
||||
- Config file: ~/.gbrain/config.json (mode 0600)
|
||||
- Setup date: {today}
|
||||
- MCP registered: {yes/no}
|
||||
- Artifacts sync: {off|artifacts-only|full}
|
||||
- Current repo policy: {read-write|read-only|deny|unset}
|
||||
```
|
||||
|
||||
**After Step 9 (smoke test) passes, also write the `## GBrain Search Guidance`
|
||||
block** so the coding agent learns when to prefer `gbrain` over Grep. This
|
||||
block is gated on the smoke test passing — write the Configuration block
|
||||
first (so the user knows what state they're in even if the smoke test fails),
|
||||
then return here after Step 9 and write the guidance block only if smoke
|
||||
test succeeded.
|
||||
|
||||
When Step 9 passes, find-and-replace (or append) this block. Use HTML-comment
|
||||
delimiters so removal regex is unambiguous and never eats user content. The
|
||||
block content is machine-AGNOSTIC — no engine type, no page counts, no
|
||||
last-sync time. Machine state stays in the Configuration block above.
|
||||
|
||||
```markdown
|
||||
## GBrain Search Guidance (configured by /sync-gbrain)
|
||||
<!-- gstack-gbrain-search-guidance:start -->
|
||||
|
||||
GBrain is set up and synced on this machine. The agent should prefer gbrain
|
||||
over Grep when the question is semantic or when you don't know the exact
|
||||
identifier yet. Two indexed corpora available via the `gbrain` CLI:
|
||||
- This repo's code (registered as `gstack-code-<repo>` source).
|
||||
- `~/.gstack/` curated memory (registered as `gstack-brain-<user>` source via
|
||||
the existing federation pipeline).
|
||||
|
||||
Prefer gbrain when:
|
||||
- "Where is X handled?" / semantic intent, no exact string yet:
|
||||
`gbrain search "<terms>"` or `gbrain query "<question>"`
|
||||
- "Where is symbol Y defined?" / symbol-based code questions:
|
||||
`gbrain code-def <symbol>` or `gbrain code-refs <symbol>`
|
||||
- "What calls Y?" / "What does Y depend on?":
|
||||
`gbrain code-callers <symbol>` / `gbrain code-callees <symbol>`
|
||||
- "What did we decide last time?" / past plans, retros, learnings:
|
||||
`gbrain search "<terms>" --source gstack-brain-<user>`
|
||||
|
||||
Grep is still right for known exact strings, regex, multiline patterns, and
|
||||
file globs. The brain auto-syncs incrementally on every gstack skill start.
|
||||
Run `/sync-gbrain` to force-refresh, `/sync-gbrain --full` for full reindex.
|
||||
|
||||
<!-- gstack-gbrain-search-guidance:end -->
|
||||
```
|
||||
|
||||
If Step 9 smoke test fails, skip the guidance block write entirely. The user's
|
||||
next `/sync-gbrain` run will re-evaluate capability and write the block when
|
||||
the round-trip works.
|
||||
> **STOP.** Before persisting the Step 8 `## GBrain Configuration` block to CLAUDE.md (and the Search Guidance block after Step 9 passes), Read `~/.claude/skills/gstack/setup-gbrain/sections/claude-md-persist.md` and execute it

|

|
||||
> working because it uses its own embedded database password."
|
||||
|
||||
### Path 2b (Supabase, manual)
|
||||
|
||||
Walk the user through the supabase.com steps:
|
||||
1. Login at https://supabase.com/dashboard
|
||||
2. Click "New Project," name it `gbrain`, pick a region, copy the generated
|
||||
database password (you'll need it for paste-back? no — it's embedded in
|
||||
the pooler URL we collect next)
|
||||
3. Wait ~2 min for the project to initialize
|
||||
4. Settings → Database → Connection Pooler → Session → copy the URL (port
|
||||
6543)
|
||||
|
||||
Then follow the same secret-read + verify + init flow as Path 1.
|
||||
|
||||
### Path 3 (PGLite local)
|
||||
|
||||
```bash
|
||||
# gstack default: voyage-code-3 (1024d) when VOYAGE_API_KEY is set — code
|
||||
# retrieval beats general-purpose embeddings on real code queries (validated
|
||||
# A/B). Without the key, gbrain auto-selects (OpenAI 1536d when available).
|
||||
# Never select gbrain's legacy zeroentropyai recipe for a new brain: the hosted
|
||||
# API sunsets September 4, 2026 (#2365); the wireup helper warns existing installs.
|
||||
set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)
|
||||
if [ -n "${VOYAGE_API_KEY:-}" ]; then
|
||||
set -- --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024
|
||||
fi
|
||||
gbrain init --pglite --json "$@"
|
||||
```
|
||||
|
||||
Done. No network, no secrets (beyond Voyage embedding API calls during sync, if
|
||||
`VOYAGE_API_KEY` is set — ~$0.18 per 1M tokens, pennies per repo).
|
||||
|
||||
### Path 4 (Remote gbrain MCP — HTTP transport with bearer token)
|
||||
|
||||
For users whose brain runs on another machine (Tailscale, ngrok, internal
|
||||
LAN, or a teammate's server). No local gbrain CLI install, no local DB.
|
||||
This skill registers the remote MCP and stops; ingestion + indexing happens
|
||||
on the brain host.
|
||||
|
||||
**4a. Collect MCP URL.** Prompt the user:
|
||||
|
||||
```
|
||||
Paste your gbrain MCP URL (e.g. https://wintermute.tail554574.ts.net:3131/mcp):
|
||||
```
|
||||
|
||||
Read with plain `read -r` (no secret hygiene needed — the URL alone isn't
|
||||
a credential). Validate it starts with `https://` (require TLS for any
|
||||
non-loopback host); refuse `http://` for non-localhost.
|
||||
|
||||
**4b. Collect bearer token via the secret-read helper (D10, never argv).**
|
||||
|
||||
```bash
|
||||
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
|
||||
read_secret_to_env GBRAIN_MCP_TOKEN "Paste bearer token: " \
|
||||
--echo-redacted 's/.\{6\}$/***REDACTED***/'
|
||||
```
|
||||
|
||||
**4c. Verify via gstack-gbrain-mcp-verify.** Run the helper; capture the
|
||||
classified JSON output:
|
||||
|
||||
```bash
|
||||
verify_json=$(GBRAIN_MCP_TOKEN="$GBRAIN_MCP_TOKEN" \
|
||||
~/.claude/skills/gstack/bin/gstack-gbrain-mcp-verify "$MCP_URL")
|
||||
status=$(echo "$verify_json" | jq -r .status)
|
||||
```
|
||||
|
||||
If `status != "success"`, the helper has already classified the failure
|
||||
into NETWORK / AUTH / MALFORMED and emitted a one-line remediation hint.
|
||||
Surface the hint above the raw error from `error_text` and **STOP** with
|
||||
a clear "fix and re-run /setup-gbrain" message. Do NOT continue to Step 5a
|
||||
on a failed verify — partial registration would leave the user with a
|
||||
half-broken state.
|
||||
|
||||
Capture two values from the verify output for downstream steps:
|
||||
- `SERVER_VERSION` (e.g., `0.27.1`) — written to the CLAUDE.md block in Step 8.
|
||||
- `URL_FORM_SUPPORTED` (`true|false`) — passed to `gstack-artifacts-init` in
|
||||
Step 7 to control which form of the brain-admin hookup command is printed.
|
||||
|
||||
**4d. (Path 4) Offer local PGLite for code search.** Per plan D10/D11, ask:
|
||||
|
||||
> D# — Want symbol-aware code search on this machine?
|
||||
> Project/branch/task: <one-sentence grounding using detected slug + branch>
|
||||
> ELI10: The remote brain at `<MCP_URL>` is great for cross-machine knowledge,
|
||||
> but symbol queries like `gbrain code-def` / `code-refs` / `code-callers` need
|
||||
> a local index of THIS machine's code. We can spin up a tiny isolated PGLite
|
||||
> database (~30 seconds, no accounts, ~120 MB disk) just for code, separate
|
||||
> from your remote brain. Transcripts and artifacts continue routing through
|
||||
> the artifacts repo to the remote brain — local PGLite stays code-only.
|
||||
> Stakes: without it, semantic code search in this repo's worktrees falls
|
||||
> back to Grep.
|
||||
> Recommendation: A — 30 seconds, no ongoing cost, unlocks the symbol tools.
|
||||
> Completeness: A=10/10 (full split-engine), B=7/10 (remote-only).
|
||||
> A) Yes, set up local PGLite for code (recommended)
|
||||
> ✅ Unlocks `gbrain code-def`, `code-refs`, `code-callers` per worktree
|
||||
> ✅ Independent engine — won't disturb remote brain or share transcripts
|
||||
> B) No, remote MCP only
|
||||
> ✅ Zero local state — only `~/.claude.json` MCP registration
|
||||
> ❌ Symbol code queries fall back to Grep in this repo's worktrees
|
||||
> Net: A = full split-engine; B = remote-only.
|
||||
|
||||
**If A (Yes)**: install + init local PGLite with rollback-safe semantics (D7):
|
||||
|
||||
```bash
|
||||
~/.claude/skills/gstack/bin/gstack-gbrain-install || exit $?
|
||||
# At this point the local gbrain CLI is on PATH. Init PGLite, but back up any
|
||||
# existing ~/.gbrain/config.json first (rollback if init fails).
|
||||
if [ -f "$HOME/.gbrain/config.json" ]; then
|
||||
BACKUP="$HOME/.gbrain/config.json.gstack-bak-$(date +%s)"
|
||||
mv "$HOME/.gbrain/config.json" "$BACKUP"
|
||||
fi
|
||||
# gstack default for local code-search PGLite: voyage-code-3 (1024d) when
|
||||
# VOYAGE_API_KEY is set. It wins the A/B over voyage-4-large and OpenAI
|
||||
# text-embedding-3-large on this codebase's symbol queries. Falls back to
|
||||
# gbrain's auto-selected provider when the key isn't present.
|
||||
set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)
|
||||
if [ -n "${VOYAGE_API_KEY:-}" ]; then
|
||||
set -- --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024
|
||||
fi
|
||||
if ! gbrain init --pglite --json "$@"; then
|
||||
if [ -n "${BACKUP:-}" ] && [ -f "$BACKUP" ]; then mv "$BACKUP" "$HOME/.gbrain/config.json"; fi
|
||||
echo "gbrain init failed. Existing config (if any) was restored. PGLite at ~/.gbrain/pglite/ may be in a partial state — \`rm -rf ~/.gbrain/pglite\` to reset." >&2
|
||||
echo "Continuing setup without local code search; you can re-run /setup-gbrain to retry." >&2
|
||||
fi
|
||||
```
|
||||
|
||||
Then continue to Step 5a. The remote-http MCP registration in 5a runs as
|
||||
today; the local PGLite is independent of MCP registration (Claude Code talks
|
||||
to the remote brain via MCP for queries; `gbrain` CLI talks to local PGLite
|
||||
for code-def/refs/callers).
|
||||
|
||||
**If B (No)**: skip the install + init. The local engine stays absent.
|
||||
`gbrain_local_status` will be `missing-config` (or `no-cli` if gbrain isn't
|
||||
installed). `/sync-gbrain` will SKIP the code stage cleanly per plan D12.
|
||||
|
||||
**4e. Skip Steps 3, 4 (other paths) and 5 (local doctor) when B was picked.**
|
||||
When A was picked, Step 3 already ran (via gstack-gbrain-install) and Step 4
|
||||
already ran (via `gbrain init --pglite`); jump straight to Step 5a. When B
|
||||
was picked, Steps 3/4/5 are no-ops; also skip Step 7.5 (transcript ingest)
|
||||
since memory-stage routes through the artifacts pipeline in remote-http mode
|
||||
per plan D11.
|
||||
|
||||
The bearer token (`GBRAIN_MCP_TOKEN`) stays in process env until Step 5a's
|
||||
`claude mcp add --header` consumes it; then `unset GBRAIN_MCP_TOKEN`
|
||||
immediately. Token security trade-off documented in
|
||||
`setup-gbrain/memory.md`: brief argv exposure during `claude mcp add`,
|
||||
resting state in `~/.claude.json` mode 0600.
|
||||
|
||||
### Switch (from detect's existing-engine state)
|
||||
|
||||
```bash
|
||||
# Going PGLite → Supabase, collect URL first (Path 1 flow), then:
|
||||

||||
# Going Supabase → PGLite:
|
||||
timeout 180s gbrain migrate --to pglite --json
|
||||
```
|

|

## Step 8: Persist `## GBrain Configuration` in CLAUDE.md
|
||||
|
||||
Find-and-replace (or append) the section. Block format depends on mode:
|
||||
CLAUDE.md is the audit trail: after a successful setup, persist the
|
||||
configuration block. The exact block formats (remote-http vs local-stdio) and
|
||||
the post-Step-9 Search Guidance write live in the claude-md-persist section.
|
||||
|
||||
### Path 4 (Remote MCP)
|
||||
|
||||
```markdown
|
||||
## GBrain Configuration (configured by /setup-gbrain)
|
||||
- Mode: remote-http
|
||||
- MCP URL: {MCP_URL}
|
||||
- Server version: gbrain v{SERVER_VERSION} (from Step 4c verify)
|
||||
- Setup date: {today}
|
||||
- MCP registered: yes (user scope)
|
||||
- Token: stored in ~/.claude.json (do not commit; never written to CLAUDE.md)
|
||||
- Artifacts repo: {gstack_artifacts_remote URL or "none"}
|
||||
- Artifacts sync: {off|artifacts-only|full}
|
||||
- Current repo policy: {read-write|read-only|deny|unset}
|
||||
```
|
||||
|
||||
The bearer token is **never** written to CLAUDE.md (CLAUDE.md is checked
|
||||
in to git in many projects). It lives only in `~/.claude.json` where
|
||||
`claude mcp add` placed it.
|
||||
|
||||
### Paths 1, 2a, 2b, 3 (Local stdio)
|
||||
|
||||
```markdown
|
||||
## GBrain Configuration (configured by /setup-gbrain)
|
||||
- Mode: local-stdio
|
||||
- Engine: {pglite|postgres}
|
||||
- Config file: ~/.gbrain/config.json (mode 0600)
|
||||
- Setup date: {today}
|
||||
- MCP registered: {yes/no}
|
||||
- Artifacts sync: {off|artifacts-only|full}
|
||||
- Current repo policy: {read-write|read-only|deny|unset}
|
||||
```
|
||||
|
||||
**After Step 9 (smoke test) passes, also write the `## GBrain Search Guidance`
|
||||
block** so the coding agent learns when to prefer `gbrain` over Grep. This
|
||||
block is gated on the smoke test passing — write the Configuration block
|
||||
first (so the user knows what state they're in even if the smoke test fails),
|
||||
then return here after Step 9 and write the guidance block only if smoke
|
||||
test succeeded.
|
||||
|
||||
When Step 9 passes, find-and-replace (or append) this block. Use HTML-comment
|
||||
delimiters so removal regex is unambiguous and never eats user content. The
|
||||
block content is machine-AGNOSTIC — no engine type, no page counts, no
|
||||
last-sync time. Machine state stays in the Configuration block above.
|
||||
|
||||
```markdown
|
||||
## GBrain Search Guidance (configured by /sync-gbrain)
|
||||
<!-- gstack-gbrain-search-guidance:start -->
|
||||
|
||||
GBrain is set up and synced on this machine. The agent should prefer gbrain
|
||||
over Grep when the question is semantic or when you don't know the exact
|
||||
identifier yet. Two indexed corpora available via the `gbrain` CLI:
|
||||
- This repo's code (registered as `gstack-code-<repo>` source).
|
||||
- `~/.gstack/` curated memory (registered as `gstack-brain-<user>` source via
|
||||
the existing federation pipeline).
|
||||
|
||||
Prefer gbrain when:
|
||||
- "Where is X handled?" / semantic intent, no exact string yet:
|
||||
`gbrain search "<terms>"` or `gbrain query "<question>"`
|
||||
- "Where is symbol Y defined?" / symbol-based code questions:
|
||||
`gbrain code-def <symbol>` or `gbrain code-refs <symbol>`
|
||||
- "What calls Y?" / "What does Y depend on?":
|
||||
`gbrain code-callers <symbol>` / `gbrain code-callees <symbol>`
|
||||
- "What did we decide last time?" / past plans, retros, learnings:
|
||||
`gbrain search "<terms>" --source gstack-brain-<user>`
|
||||
|
||||
Grep is still right for known exact strings, regex, multiline patterns, and
|
||||
file globs. The brain auto-syncs incrementally on every gstack skill start.
|
||||
Run `/sync-gbrain` to force-refresh, `/sync-gbrain --full` for full reindex.
|
||||
|
||||
<!-- gstack-gbrain-search-guidance:end -->
|
||||
```
|
||||
|
||||
If Step 9 smoke test fails, skip the guidance block write entirely. The user's
|
||||
next `/sync-gbrain` run will re-evaluate capability and write the block when
|
||||
the round-trip works.

Then:
|
||||
|
||||
```bash
|
||||
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
|
||||
read_secret_to_env SUPABASE_ACCESS_TOKEN "Paste PAT: "
|
||||
```
|
||||
|
||||
Ask the D17 tier prompt via AskUserQuestion: "Which Supabase tier?" Present
|
||||
Free (2-project limit, pauses after 7d inactivity) vs Pro ($25/mo, no
|
||||
pauses, recommended for real use). Explain that tier is **org-level** (per
|
||||
the Management API contract) — user picks their org based on its current
|
||||
tier. Pro may require them to upgrade the org first at supabase.com.
|
||||
|
||||
List orgs, pick one (AskUserQuestion if multiple):
|
||||
|
||||
```bash
|
||||
orgs=$(~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision list-orgs --json)
|
||||
```
|
||||
|
||||
If the `.orgs` array is empty, surface: "Your Supabase account has no
|
||||
organizations. Create one at https://supabase.com/dashboard, then re-run
|
||||
`/setup-gbrain`." STOP.
|
||||
|
||||
Ask the user for a region (default `us-east-1`; valid values are the 18
|
||||
enum values in the Supabase Management API — list a few common ones, let
|
||||
them pick "Other" for a full list).
|
||||
|
||||
Generate the DB password (never shown to the user):
|
||||
|
||||
```bash
|
||||
export DB_PASS=$(openssl rand -base64 24)
|
||||
```
|
||||
|
||||
Set up a SIGINT trap (D12 basic recovery):
|
||||
|
||||
```bash
|
||||
trap 'echo ""; echo "gstack-gbrain: interrupted. In-flight ref: $INFLIGHT_REF"; \
|
||||
echo "Resume: /setup-gbrain --resume-provision $INFLIGHT_REF"; \

|
||||
```bash
|
||||
result=$(~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision \

||||
create gbrain "$REGION" "$ORG_SLUG" --json)

|
||||
|
||||

|
||||

|
||||
> working because it uses its own embedded database password."
|
||||
|
||||
### Path 2b (Supabase, manual)
|
||||
|
||||
Walk the user through the supabase.com steps:
|
||||
1. Login at https://supabase.com/dashboard
|
||||
2. Click "New Project," name it `gbrain`, pick a region, copy the generated
|
||||
database password (you'll need it for paste-back? no — it's embedded in
|
||||
the pooler URL we collect next)
|
||||
3. Wait ~2 min for the project to initialize
|
||||
4. Settings → Database → Connection Pooler → Session → copy the URL (port
|
||||
6543)
|
||||
|
||||
Then follow the same secret-read + verify + init flow as Path 1.
|
||||
|
||||
### Path 3 (PGLite local)
|
||||
|
||||
```bash
|
||||
# gstack default: voyage-code-3 (1024d) when VOYAGE_API_KEY is set — code
|
||||
# retrieval beats general-purpose embeddings on real code queries (validated
|
||||
# A/B). Without the key, gbrain auto-selects (OpenAI 1536d when available).
|
||||
# Never select gbrain's legacy zeroentropyai recipe for a new brain: the hosted
|
||||
# API sunsets September 4, 2026 (#2365); the wireup helper warns existing installs.
|
||||
set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)
|
||||
if [ -n "${VOYAGE_API_KEY:-}" ]; then
|
||||
set -- --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024
|
||||
fi
|
||||
gbrain init --pglite --json "$@"
|
||||
```
|
||||
|
||||
Done. No network, no secrets (beyond Voyage embedding API calls during sync, if
|
||||
`VOYAGE_API_KEY` is set — ~$0.18 per 1M tokens, pennies per repo).
|
||||
|
||||
### Path 4 (Remote gbrain MCP — HTTP transport with bearer token)
|
||||
|
||||
For users whose brain runs on another machine (Tailscale, ngrok, internal
|
||||
LAN, or a teammate's server). No local gbrain CLI install, no local DB.
|
||||
This skill registers the remote MCP and stops; ingestion + indexing happens
|
||||
on the brain host.
|
||||
|
||||
**4a. Collect MCP URL.** Prompt the user:
|
||||
|
||||
```
|
||||
Paste your gbrain MCP URL (e.g. https://wintermute.tail554574.ts.net:3131/mcp):
|
||||
```
|
||||
|
||||
Read with plain `read -r` (no secret hygiene needed — the URL alone isn't
|
||||
a credential). Validate it starts with `https://` (require TLS for any
|
||||
non-loopback host); refuse `http://` for non-localhost.
|
||||
|
||||
**4b. Collect bearer token via the secret-read helper (D10, never argv).**
|
||||
|
||||
```bash
|
||||
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
|
||||
read_secret_to_env GBRAIN_MCP_TOKEN "Paste bearer token: " \
|
||||
--echo-redacted 's/.\{6\}$/***REDACTED***/'
|
||||
```
|
||||
|
||||
**4c. Verify via gstack-gbrain-mcp-verify.** Run the helper; capture the
|
||||
classified JSON output:
|
||||
|
||||
```bash
|
||||
verify_json=$(GBRAIN_MCP_TOKEN="$GBRAIN_MCP_TOKEN" \
|
||||
~/.claude/skills/gstack/bin/gstack-gbrain-mcp-verify "$MCP_URL")
|
||||
status=$(echo "$verify_json" | jq -r .status)
|
||||
```
|
||||
|
||||
If `status != "success"`, the helper has already classified the failure
|
||||
into NETWORK / AUTH / MALFORMED and emitted a one-line remediation hint.
|
||||
Surface the hint above the raw error from `error_text` and **STOP** with
|
||||
a clear "fix and re-run /setup-gbrain" message. Do NOT continue to Step 5a
|
||||
on a failed verify — partial registration would leave the user with a
|
||||
half-broken state.
|
||||
|
||||
Capture two values from the verify output for downstream steps:
|
||||
- `SERVER_VERSION` (e.g., `0.27.1`) — written to the CLAUDE.md block in Step 8.
|
||||
- `URL_FORM_SUPPORTED` (`true|false`) — passed to `gstack-artifacts-init` in
|
||||
Step 7 to control which form of the brain-admin hookup command is printed.
|
||||
|
||||
**4d. (Path 4) Offer local PGLite for code search.** Per plan D10/D11, ask:
|
||||
|
||||
> D# — Want symbol-aware code search on this machine?
|
||||
> Project/branch/task: <one-sentence grounding using detected slug + branch>
|
||||
> ELI10: The remote brain at `<MCP_URL>` is great for cross-machine knowledge,
|
||||
> but symbol queries like `gbrain code-def` / `code-refs` / `code-callers` need
|
||||
> a local index of THIS machine's code. We can spin up a tiny isolated PGLite
|
||||
> database (~30 seconds, no accounts, ~120 MB disk) just for code, separate
|
||||
> from your remote brain. Transcripts and artifacts continue routing through
|
||||
> the artifacts repo to the remote brain — local PGLite stays code-only.
|
||||
> Stakes: without it, semantic code search in this repo's worktrees falls
|
||||
> back to Grep.
|
||||
> Recommendation: A — 30 seconds, no ongoing cost, unlocks the symbol tools.
|
||||
> Completeness: A=10/10 (full split-engine), B=7/10 (remote-only).
|
||||
> A) Yes, set up local PGLite for code (recommended)
|
||||
> ✅ Unlocks `gbrain code-def`, `code-refs`, `code-callers` per worktree
|
||||
> ✅ Independent engine — won't disturb remote brain or share transcripts
|
||||
> B) No, remote MCP only
|
||||
> ✅ Zero local state — only `~/.claude.json` MCP registration
|
||||
> ❌ Symbol code queries fall back to Grep in this repo's worktrees
|
||||
> Net: A = full split-engine; B = remote-only.
|
||||
|
||||
**If A (Yes)**: install + init local PGLite with rollback-safe semantics (D7):
|
||||
|
||||
```bash
|
||||
~/.claude/skills/gstack/bin/gstack-gbrain-install || exit $?
|
||||
# At this point the local gbrain CLI is on PATH. Init PGLite, but back up any
|
||||
# existing ~/.gbrain/config.json first (rollback if init fails).
|
||||
if [ -f "$HOME/.gbrain/config.json" ]; then
|
||||
BACKUP="$HOME/.gbrain/config.json.gstack-bak-$(date +%s)"
|
||||
mv "$HOME/.gbrain/config.json" "$BACKUP"
|
||||
fi
|
||||
# gstack default for local code-search PGLite: voyage-code-3 (1024d) when
|
||||
# VOYAGE_API_KEY is set. It wins the A/B over voyage-4-large and OpenAI
|
||||
# text-embedding-3-large on this codebase's symbol queries. Falls back to
|
||||
# gbrain's auto-selected provider when the key isn't present.
|
||||
set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)
|
||||
if [ -n "${VOYAGE_API_KEY:-}" ]; then
|
||||
set -- --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024
|
||||
fi
|
||||
if ! gbrain init --pglite --json "$@"; then
|
||||
if [ -n "${BACKUP:-}" ] && [ -f "$BACKUP" ]; then mv "$BACKUP" "$HOME/.gbrain/config.json"; fi
|
||||
echo "gbrain init failed. Existing config (if any) was restored. PGLite at ~/.gbrain/pglite/ may be in a partial state — \`rm -rf ~/.gbrain/pglite\` to reset." >&2
|
||||
echo "Continuing setup without local code search; you can re-run /setup-gbrain to retry." >&2
|
||||
fi
|
||||
```
|
||||
|
||||
Then continue to Step 5a. The remote-http MCP registration in 5a runs as
|
||||
today; the local PGLite is independent of MCP registration (Claude Code talks
|
||||
to the remote brain via MCP for queries; `gbrain` CLI talks to local PGLite
|
||||
for code-def/refs/callers).
|
||||
|
||||
**If B (No)**: skip the install + init. The local engine stays absent.
|
||||
`gbrain_local_status` will be `missing-config` (or `no-cli` if gbrain isn't
|
||||
installed). `/sync-gbrain` will SKIP the code stage cleanly per plan D12.
|
||||
|
||||
**4e. Skip Steps 3, 4 (other paths) and 5 (local doctor) when B was picked.**
|
||||
When A was picked, Step 3 already ran (via gstack-gbrain-install) and Step 4
|
||||
already ran (via `gbrain init --pglite`); jump straight to Step 5a. When B
|
||||
was picked, Steps 3/4/5 are no-ops; also skip Step 7.5 (transcript ingest)
|
||||
since memory-stage routes through the artifacts pipeline in remote-http mode
|
||||
per plan D11.
|
||||
|
||||
The bearer token (`GBRAIN_MCP_TOKEN`) stays in process env until Step 5a's
|
||||
`claude mcp add --header` consumes it; then `unset GBRAIN_MCP_TOKEN`
|
||||
immediately. Token security trade-off documented in
|
||||
`setup-gbrain/memory.md`: brief argv exposure during `claude mcp add`,
|
||||
resting state in `~/.claude.json` mode 0600.
|
||||
|
||||
### Switch (from detect's existing-engine state)
|
||||
|
||||
```bash
|
||||
# Going PGLite → Supabase, collect URL first (Path 1 flow), then:

|
||||
|
||||
### Path 1 (Supabase, existing URL)
|
||||
|
||||
Source the secret-read helper, collect URL with `read -s` + redacted preview:
|
||||
|
||||
```bash
|
||||
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
|

read_secret_to_env GBRAIN_POOLER_URL "Paste Session Pooler URL: " \
|
||||
--echo-redacted 's#://[^@]*@#://***@#'

If the verify exit code is 3 (direct-connection URL), the verifier's own
|
||||

```bash

now persisted in `~/.gbrain/config.json` at mode 0600 by gbrain itself.
|
||||
|
||||
### Path 2a (Supabase, auto-provision — D7)

Show the D11 PAT scope disclosure verbatim BEFORE collecting the token:

||||
```
|
||||
|
||||
If `status != "success"`, the helper has already classified the failure
|
||||
into NETWORK / AUTH / MALFORMED and emitted a one-line remediation hint.
|
||||
Surface the hint above the raw error from `error_text` and **STOP** with
|
||||
a clear "fix and re-run /setup-gbrain" message. Do NOT continue to Step 5a
|
||||
on a failed verify — partial registration would leave the user with a
|
||||
half-broken state.
|
||||
|
||||
Capture two values from the verify output for downstream steps:
|
||||
- `SERVER_VERSION` (e.g., `0.27.1`) — written to the CLAUDE.md block in Step 8.
|
||||
- `URL_FORM_SUPPORTED` (`true|false`) — passed to `gstack-artifacts-init` in
|
||||
Step 7 to control which form of the brain-admin hookup command is printed.
|
||||
|
||||
**4d. (Path 4) Offer local PGLite for code search.** Per plan D10/D11, ask:
|
||||
|
||||
> D# — Want symbol-aware code search on this machine?
|
||||
> Project/branch/task: <one-sentence grounding using detected slug + branch>
|
||||
> ELI10: The remote brain at `<MCP_URL>` is great for cross-machine knowledge,
|
||||
> but symbol queries like `gbrain code-def` / `code-refs` / `code-callers` need
|
||||
> a local index of THIS machine's code. We can spin up a tiny isolated PGLite
|
||||
> database (~30 seconds, no accounts, ~120 MB disk) just for code, separate
|
||||
> from your remote brain. Transcripts and artifacts continue routing through
|
||||
> the artifacts repo to the remote brain — local PGLite stays code-only.
|
||||
> Stakes: without it, semantic code search in this repo's worktrees falls
|
||||
> back to Grep.
|
||||
> Recommendation: A — 30 seconds, no ongoing cost, unlocks the symbol tools.
|
||||
> Completeness: A=10/10 (full split-engine), B=7/10 (remote-only).
|
||||
> A) Yes, set up local PGLite for code (recommended)
|
||||
> ✅ Unlocks `gbrain code-def`, `code-refs`, `code-callers` per worktree
|
||||
> ✅ Independent engine — won't disturb remote brain or share transcripts
|
||||
> B) No, remote MCP only
|
||||
> ✅ Zero local state — only `~/.claude.json` MCP registration
|
||||
> ❌ Symbol code queries fall back to Grep in this repo's worktrees
|
||||
> Net: A = full split-engine; B = remote-only.
|
||||
|
||||
**If A (Yes)**: install + init local PGLite with rollback-safe semantics (D7):
|
||||
|
||||
```bash
|
||||
~/.claude/skills/gstack/bin/gstack-gbrain-install || exit $?
|
||||
# At this point the local gbrain CLI is on PATH. Init PGLite, but back up any
|
||||
# existing ~/.gbrain/config.json first (rollback if init fails).
|
||||
if [ -f "$HOME/.gbrain/config.json" ]; then
|
||||
BACKUP="$HOME/.gbrain/config.json.gstack-bak-$(date +%s)"
|
||||
mv "$HOME/.gbrain/config.json" "$BACKUP"
|
||||
fi
|
||||
# gstack default for local code-search PGLite: voyage-code-3 (1024d) when
|
||||
# VOYAGE_API_KEY is set. It wins the A/B over voyage-4-large and OpenAI
|
||||
# text-embedding-3-large on this codebase's symbol queries. Falls back to
|
||||
# gbrain's auto-selected provider when the key isn't present.
|
||||
set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)
|
||||
if [ -n "${VOYAGE_API_KEY:-}" ]; then
|
||||
set -- --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024
|
||||
fi
|
||||
if ! gbrain init --pglite --json "$@"; then
|
||||
if [ -n "${BACKUP:-}" ] && [ -f "$BACKUP" ]; then mv "$BACKUP" "$HOME/.gbrain/config.json"; fi
|
||||
echo "gbrain init failed. Existing config (if any) was restored. PGLite at ~/.gbrain/pglite/ may be in a partial state — \`rm -rf ~/.gbrain/pglite\` to reset." >&2
|
||||
echo "Continuing setup without local code search; you can re-run /setup-gbrain to retry." >&2
|
||||
fi
|
||||
```
|
||||
|
||||
Then continue to Step 5a. The remote-http MCP registration in 5a runs as
|
||||
today; the local PGLite is independent of MCP registration (Claude Code talks
|
||||
to the remote brain via MCP for queries; `gbrain` CLI talks to local PGLite
|
||||
for code-def/refs/callers).
|
||||
|
||||
**If B (No)**: skip the install + init. The local engine stays absent.
|
||||
`gbrain_local_status` will be `missing-config` (or `no-cli` if gbrain isn't
|
||||
installed). `/sync-gbrain` will SKIP the code stage cleanly per plan D12.
|
||||
|
||||
**4e. Skip Steps 3, 4 (other paths) and 5 (local doctor) when B was picked.**
|
||||
When A was picked, Step 3 already ran (via gstack-gbrain-install) and Step 4
|
||||
already ran (via `gbrain init --pglite`); jump straight to Step 5a. When B
|
||||
was picked, Steps 3/4/5 are no-ops; also skip Step 7.5 (transcript ingest)
|
||||
since memory-stage routes through the artifacts pipeline in remote-http mode
|
||||
per plan D11.
|
||||
|
||||
The bearer token (`GBRAIN_MCP_TOKEN`) stays in process env until Step 5a's
|
||||
`claude mcp add --header` consumes it; then `unset GBRAIN_MCP_TOKEN`
|
||||
immediately. Token security trade-off documented in
|
||||
`setup-gbrain/memory.md`: brief argv exposure during `claude mcp add`,
|
||||
resting state in `~/.claude.json` mode 0600.
|
||||
|
||||
### Switch (from detect's existing-engine state)
|
||||
|
||||
```bash
|
||||
# Going PGLite → Supabase, collect URL first (Path 1 flow), then:
|
||||
timeout 180s gbrain migrate --to supabase --url "$URL" --json
|
||||
# Going Supabase → PGLite:
|
||||
timeout 180s gbrain migrate --to pglite --json
|
||||
```
|
||||
|
||||
If `timeout` returns 124 (exit code for timeout): surface D9 message
|
||||
("Migration didn't complete in 3 minutes — another gstack session may be
|
||||
holding a lock on the source brain. Close other workspaces and re-run
|
||||

# Never select gbrain's legacy zeroentropyai recipe for a new brain: the hosted
|

# API sunsets September 4, 2026 (#2365); the wireup helper warns existing installs.

set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)

echo "PGLite directory at ~/.gbrain/pglite/ may be in a partial state — \`rm -rf ~/.gbrain/pglite\` if needed before retrying." >&2

exit 1

fi
|
||||
echo "Switched to local PGLite. Previous config saved at $BACKUP — review before deleting."
|
||||
```
|

|

Then jump to Step 5a (MCP registration; the new PGLite engine is registered as
|

local-stdio).
|

|

**If C (Switch brain mode)**: continue to Step 2's normal path picker.
|
||||
|

**If D (Quit)**: STOP the skill cleanly.
