/autoplan driver: run the review loop from a parent agent

Read this file instead of autoplan/SKILL.md when you (a parent agent on any host) drive an unattended /autoplan run through gstack-autoplan: the reviewers are subagents you dispatch, and the runner keeps the state. The commands live in <root>/bin/, where <root> is the folder that holds this autoplan/ directory; gstack-autoplan --help and the first next print DRIVER: <root>/autoplan/DRIVER.md. Run every command with the GSTACK_LAUNCH assignments your installer printed. Read printed lines and files, never prose: every workflow command ends with GSTACK_RESULT: skill=autoplan status=<s> run=<dir>, and every error line ends with (<CODE>).

Phases and scope

Order: ceo → design → dx → eng. Design runs only with UI scope, DX only with DX scope, Eng always and last. Scope flags on the first next: --ui, --no-ui, --no-dx, --developer-tool, --agent-primary. --developer-tool and --agent-primary only enable DX. The first next prints SCOPE: ui=… (terms; visual; files) dx=… (detected) source=ui:<s>,dx:<s> (each axis is flag, marker or detected). UI needs a rendered file path or a UI term next to a visual noun in the Implementation plan. To keep flags for later runs on the same plan, add the SCOPE_PIN: marker it prints (<!-- gstack-autoplan-scope: … -->) as the plan's first line yourself; gstack never writes the plan.

The loop

1. next prints one ATTEMPT: <id> phase=<p> voice=native|outside prompt=<file> result=<file> per voice. Dispatch the native prompt to a subagent on your model and the outside prompt to a subagent on another model family (or gstack-outside-voice run). Each writes result=.
2. Submit each voice exactly once (BOUND:). Both voices in closes the phase (PHASE_CLOSED:).
3. Repeat next until status=gate_pending (GATE: gate_rev=<n>); render it with gstack-gate render <dir>/gate.json --all and relay every page. You never approve the gate for the owner. Offer rec (every recommendation, plan changes included) as the default.
4. answer with the owner's reply and --by human (the owner typed the tokens) or --by agent:<id> --owner-reply "<their words>" (you relayed them); without --by an unattended run refuses (ANSWER_BY_REQUIRED). APPLY: <id> <title> -> <change> lines are accepted plan changes (status amend_pending): edit the plan, then revise (the printed NEXT: names it), or revise --settle <id> when the line says no plan edit is needed. Until then next refuses with PLAN_AMEND_PENDING and export will not mark the run complete.
5. REOPENED: <phases> means loop next again (Eng last). APPROVED: means export.

On Capy

• Always drive gstack-autoplan; never hand-adapt autoplan/SKILL.md. A plan you reviewed by hand is not an autoplan run: do not present it as one.
• Set GSTACK_AUTOPLAN_CHECKPOINT_DIR to the private project-user Drive folder so a run at rest survives machine replacement; restore with resume --out <new dir> --from <dir>/<run>.

Commands

• gstack-autoplan next --out <dir> --plan <plan.md> [scope flags] [--light] [--spend-cap <usd>] [--scaffold] first call: init the run, print PHASE:, SCOPE:, DRIVER: and one ATTEMPT: per voice.
• gstack-autoplan next --out <dir> [--redispatch <attempt>] later calls: open the next phase or reprint open attempts; never redispatches on its own.
• gstack-autoplan submit --out <dir> --phase <p> --voice native|outside --record <file.md> --model <id> [--attempt <id>] bind a free-form review record (canonical fence, one findings table or list, or No findings.).
• gstack-autoplan submit ... --record <file.md> --attest "<reason>" --attempt <id> bind a record with no INPUT: line as receipt: attested (a wrong INPUT: always refuses).
• gstack-autoplan submit --out <dir> --phase <p> --voice native|outside --result <file> --model <id> --attempt <id> bind a canonical result (the RESULT FORMAT below).
• gstack-autoplan submit --out <dir> --phase <p> --voice outside --unavailable|--failed "<reason>" close the phase native-only when no outside voice can run.
• gstack-autoplan answer --out <dir> --gate-rev <n> --reply "<reply>" --by human|agent:<id> [--owner-reply <text>|-] [--rec-hash <h>] answer the gate with the reply grammar below; an agent answer stores the owner's words verbatim.
• gstack-autoplan recommend --out <dir> --gate-rev <n> --item <id> --option <k> --basis "<why>" change one recommendation before relay; then render and relay again (a rec needs the new --rec-hash).
• gstack-autoplan revise --out <dir> --plan <plan v2> --incorporates <decision ids> bind the amended plan; reopens every phase whose reviewed plan changed, Eng last.
• gstack-autoplan revise --out <dir> --settle <decision id|d4> discharge a packaging or ordering change with no plan edit; reopens nothing.
• gstack-autoplan revise --out <dir> --withdraw <decision id> drop a pending amendment instead of applying it.
• gstack-autoplan export --out <dir> write the artifact set; then gstack-artifact validate <dir>/run.json.
• gstack-autoplan status|resume --out <dir> read the manifest (PENDING: lines name open attempts); take ownership after a crash (EXECUTION_UNKNOWN lists unfinished attempts).
• gstack-autoplan resume --out <new dir> --from <checkpoint> restore the newest valid checkpoint generation (GSTACK_AUTOPLAN_CHECKPOINT_DIR) into an empty directory and take ownership; checkpoints --from <dir> lists them.

Reviewer result format

Every prompt ends with this contract; submit --result enforces it, submit --record accepts the looser record shapes above.

RESULT FORMAT (required by gstack-autoplan; the parent binds your file by this contract):

1. The first line of your result is exactly: INPUT:
2. Write the complete review as prose, then END with one fenced block of canonical findings, one JSON object per line:

{"id":"F1","severity":"High","title":"<one line>","file":"<path or omit>","line":12,"fix":"<the fix>"}

severity is Critical | High | Medium | Low | Informational. Add "user_challenge": true only when you recommend changing the plan's stated direction AND the change alters its scope, cost or direction (then also add "changes": "scope" | "cost" | "direction") or only its delivery packaging or ordering, with no Implementation-plan edit (then "changes": "packaging" | "ordering"). Naming and other reversible choices are ordinary findings, not user challenges. Add "urgent": true and "suggested_owner": "" for a security or data-loss finding this plan does not own. An empty fence means no findings; a missing fence is refused. 3. Write the whole result to this file:

Gate replies

A reply binds to the gate_rev you read (--gate-rev). Bare yes/no is unparsed, never guessed.

• rec: every item takes its recommendation, plan changes included (each prints APPLY:); all is an alias.
• as-is: keep every direction; no plan change.
• d3b uc1a: one token per item you set; unanswered auto items take their default.
• rec except d3b: recommendations, with the listed overrides.

Run directory

Runner state: run.json, attempts.jsonl, run.lock, spend.json, plan-active.md, restore.md, plan-source.md. Reviewer files: <phase>-native-prompt.md, <phase>-outside-prompt.md, <phase>-<voice>.<attempt>.md (the reviewer writes it), its sealed <phase>-<voice>.<attempt>.bound.md (what submit bound), <phase>-consensus.{json,md}, gate.json, decisions.jsonl. export writes plan.md, review-record.md, findings.jsonl, tasks.jsonl, timing.json and rehashes run.json; gstack-artifact validate <dir>/run.json is the completion check. Copy the whole directory, never single files.

Result codes

• RUN_NOT_INITIALIZED: start with gstack-autoplan next --plan <file> --out <dir> (the first call initializes the run)
• PLAN_SECTIONS_INVALID: add the missing heading, or rerun the first gstack-autoplan next with --scaffold to review a scaffolded copy (your plan file is never edited); duplicate, reversed or empty sections are fixed by hand
• RUN_LOCKED: wait for it to exit, or if its pid is gone run gstack-autoplan resume --out <dir> to take ownership
• EXECUTION_UNKNOWN: submit the result file if the reviewer finished (gstack-autoplan submit ... --attempt <id>), or redispatch explicitly with gstack-autoplan next --redispatch <id>; nothing is redispatched automatically
• SPEND_CAP_EXCEEDED: raise --spend-cap, settle or release unsettled attempts, or stop; unknown charges count as their reservation
• PHASE_NOT_AWAITING: run gstack-autoplan status --out <dir> and submit for the attempt next printed
• ATTEMPT_MISMATCH: pass the attempt id next printed for this voice; a result is bound exactly once
• RESULT_RECEIPT_MISSING: the reviewer must read the prompt file through EOF and begin its result with the INPUT line the prompt names; a result for another snapshot is refused
• RESULT_FINDINGS_MISSING: end the review with one ```gstack-findings fence, one JSON object per line with at least severity and title; [] rows are not findings, an empty fence means no findings
• MODEL_FAMILY_CONFLICT: pass --model <id> of a different family (anthropic, openai, google, xai, deepseek, qwen, zai, moonshot, meta, mistral); a same-family result is not an outside voice
• CONSENSUS_MISSING: resume the run so the phase closes through reconciliation; the Eng prompt is never sent without every prior phase summary
• GATE_REV_STALE: render the current gate list, read it, and reply with its gate_rev
• GATE_REPLY_UNPARSED: reply with rec, as-is, <id><option> tokens (for example d3b uc1a), or rec except <tokens>; bare yes/no is ambiguous
• GATE_REC_STALE: render the gate again (gstack-gate render <dir>/gate.json --all), relay it, and answer with the printed --rec-hash
• OWNER_REPLY_REQUIRED: pass the owner's words exactly with --owner-reply "<text>", --owner-reply - (stdin) or --owner-reply-file <path>
• GATE_OWNER_REPLY_MISMATCH: relay exactly what the owner chose (or their reply itself, e.g. --reply rec); ask the owner when their words and the tokens disagree
• PLAN_AMEND_PENDING: edit the plan, then gstack-autoplan revise --out <dir> --plan <file> --incorporates <decision id,...>; settle a packaging or ordering change with gstack-autoplan revise --out <dir> --settle <id>; or drop one with gstack-autoplan revise --out <dir> --withdraw <decision id>
• AMENDMENT_NOT_SETTLEABLE: edit the plan, then gstack-autoplan revise --out <dir> --plan <file> --incorporates <decision id> (add --settle <id> to settle packaging/ordering changes in the same call); settle alone only on the plan the run already reviews
• CHECKPOINT_INVALID: run gstack-autoplan checkpoints --from <dir> to see each generation's hash status and restore an intact one; nothing was written to --out
• GSTACK_VERSION_CHANGED: nothing to do for an older run (journaled forward migrations ran); a run written by a newer gstack needs that gstack: upgrade with bin/gstack-upgrade

Coordinator contract (inherited by every lane)

Merge conditions. A lane's PR merges only when: the required gate lanes are green on the stamped tree or the tree receipt says gate-reuse: eligible; gstack-lane-check reports clear for its planned files against every other open lane; the PR body opens with the gstack-ship-receipt block; and the coordinator, not the lane, says merge. A lane never merges, rebases another lane, or force-pushes.

Behavior-change notices. Every user-visible behavior change outside the plan's own items is listed in the PR body under ## Behavior changes with the file, the old behavior and the new one, before the review starts. An omitted change found in review is a CRITICAL finding, whatever its size.

Spend caps. Each lane runs under the --spend-cap the coordinator names; a lane that reaches it stops with status=budget_exhausted and reports spent, reserved and unknown charges. Paid evals are never retried to change a verdict; a rerun needs a named repair. Host-subagent spend is reported as unknown, never zero.

Before done. A lane runs gstack-pregate run --allow-repo-commands on its branch (the unit tier on the changed files plus the repo's guards) and reports done only after it passes. In a repo whose .gstack/pregate.json has a sealed key, it runs gstack-pregate sealed before any push or PR creation; a refusal stops the push, because a PR tool may not run local hooks.

Handoff format. A lane reports in this order, identifiers first: PR URL (or no PR with branch and SHA), GSTACK_RESULT line, the gstack: ok|fail <rev> line, the PREGATE: line, gate summary (lanes passed/failed/skipped), behavior changes (or none), spend (spent/reserved/unknown), then what it could not verify. Full thread ids (jam_…), never short codes, in every cross-thread message. Prose after the identifiers may be truncated; nothing before them may be.
