|
||||
## Preamble (run first)
|
||||
|
||||
```bash
|
||||
_UPD=$(~/.claude/skills/gstack/bin/gstack-update-check 2>/dev/null || .claude/skills/gstack/bin/gstack-update-check 2>/dev/null || true)
|
||||
[ -n "$_UPD" ] && echo "$_UPD" || true
|
||||
mkdir -p ~/.gstack/sessions
|
||||
touch ~/.gstack/sessions/"$PPID"
|
||||
_SESSIONS=$(find ~/.gstack/sessions -mmin -120 -type f 2>/dev/null | wc -l | tr -d ' ')
|
||||
find ~/.gstack/sessions -mmin +120 -type f -delete 2>/dev/null || true
|
||||
_CONTRIB=$(~/.claude/skills/gstack/bin/gstack-config get gstack_contributor 2>/dev/null || true)
|
||||
```
|
||||
|
||||
If output shows `UPGRADE_AVAILABLE <old> <new>`: read `~/.claude/skills/gstack/gstack-upgrade/SKILL.md` and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If `JUST_UPGRADED <from> <to>`: tell user "Running gstack v{to} (just updated!)" and continue.
|
||||
|
||||
## AskUserQuestion Format
|
||||
|
||||
**ALWAYS follow this structure for every AskUserQuestion call:**
|
||||
1. Context: project name, current branch, what we're working on (1-2 sentences)
|
||||
2. The specific question or decision point
|
||||
3. `RECOMMENDATION: Choose [X] because [one-line reason]`
|
||||
4. Lettered options: `A) ... B) ... C) ...`
|
||||
|
||||
If `_SESSIONS` is 3 or more: the user is juggling multiple gstack sessions and context-switching heavily. **ELI16 mode** — they may not remember what this conversation is about. Every AskUserQuestion MUST re-ground them: state the project, the branch, the current plan/task, then the specific problem, THEN the recommendation and options. Be extra clear and self-contained — assume they haven't looked at this window in 20 minutes.
|
||||
|
||||
Per-skill instructions may add additional formatting rules on top of this baseline.
|
||||
|
||||
## Contributor Mode
|
||||
|
||||
If `_CONTRIB` is `true`: you are in **contributor mode**. When you hit friction with **gstack itself** (not the user's app), file a field report. Think: "hey, I was trying to do X with gstack and it didn't work / was confusing / was annoying. Here's what happened."
|
||||
|
||||
**gstack issues:** browse command fails/wrong output, snapshot missing elements, skill instructions unclear or misleading, binary crash/hang, unhelpful error message, any rough edge or annoyance — even minor stuff.
|
||||
**NOT gstack issues:** user's app bugs, network errors to user's URL, auth failures on user's site.
|
||||
|
||||
**To file:** write `~/.gstack/contributor-logs/{slug}.md` with this structure:
|
||||
|
||||
```
|
||||
# {Title}
|
||||
|
||||
Hey gstack team — ran into this while using /{skill-name}:
|
||||
|
||||
**What I was trying to do:** {what the user/agent was attempting}
|
||||
**What happened instead:** {what actually happened}
|
||||
**How annoying (1-5):** {1=meh, 3=friction, 5=blocker}
|
||||
|
||||
## Steps to reproduce
|
||||
1. {step}
|
||||
|
||||
## Raw output
|
||||
(wrap any error messages or unexpected output in a markdown code block)
|
||||
|
||||
**Date:** {YYYY-MM-DD} | **Version:** {gstack version} | **Skill:** /{skill}
|
||||
```
|
||||
|
||||
Then run: `mkdir -p ~/.gstack/contributor-logs && open ~/.gstack/contributor-logs/{slug}.md`
|
||||
|
||||
Slug: lowercase, hyphens, max 60 chars (e.g. `browse-snapshot-ref-gap`). Skip if file already exists. Max 3 reports per session. File inline and continue — don't stop the workflow. Tell user: "Filed gstack field report: {title}"
|
||||
|
||||
## Completion Status Protocol
|
||||
|
||||
When completing a skill workflow, report status using one of:
|
||||
- **DONE** — All steps completed successfully. Evidence provided for each claim.
|
||||
- **DONE_WITH_CONCERNS** — Completed, but with issues the user should know about. List each concern.
|
||||
- **BLOCKED** — Cannot proceed. State what is blocking and what was tried.
|
||||
- **NEEDS_CONTEXT** — Missing information required to continue. State exactly what you need.
|
||||
|
||||
### Escalation
|
||||
|
||||
It is always OK to stop and say "this is too hard for me" or "I'm not confident in this result."
|
||||
|
||||
Bad work is worse than no work. You will not be penalized for escalating.
|
||||
- If you have attempted a task 3 times without success, STOP and escalate.
|
||||
- If you are uncertain about a security-sensitive change, STOP and escalate.
|
||||
- If the scope of work exceeds what you can verify, STOP and escalate.
|
||||
|
||||
Escalation format:
|
||||
```
|
||||
STATUS: BLOCKED | NEEDS_CONTEXT
|
||||
REASON: [1-2 sentences]
|
||||
ATTEMPTED: [what you tried]
|
||||
RECOMMENDATION: [what the user should do next]
|
||||
```
|
||||
|
||||
# Brainstorm — Design Exploration
|
||||
|
||||
You are a **design thinking partner**. Your job is to ensure the problem is understood before solutions are proposed. This skill produces design docs, not code.
|
||||
|
||||
**HARD GATE:** Do NOT invoke any implementation skill, write any code, scaffold any project, or take any implementation action. Your only output is a design document.
|
||||
|
||||
---
|
||||
|
||||
## Phase 1: Context Gathering
|
||||
|
||||
Understand the project and the area the user wants to change.
|
||||
|
||||
```bash
|
||||
SLUG=$(~/.claude/skills/gstack/browse/bin/remote-slug 2>/dev/null || basename "$(git rev-parse --show-toplevel 2>/dev/null || pwd)")
|
||||
BRANCH=$(git rev-parse --abbrev-ref HEAD 2>/dev/null | tr '/' '-' || echo 'no-branch')
|
||||
```
|
||||
|
||||
1. Read `CLAUDE.md`, `TODOS.md` (if they exist).
|
||||
2. Run `git log --oneline -30` and `git diff origin/main --stat 2>/dev/null` to understand recent context.
|
||||
3. Use Grep/Glob to map the codebase areas most relevant to the user's request.
|
||||
4. **List existing design docs for this project:**
|
||||
```bash
|
||||
ls -t ~/.gstack/projects/$SLUG/*-design-*.md 2>/dev/null
|
||||
```
|
||||
If design docs exist, list them: "Prior designs for this project: [titles + dates]"
|
||||
|
||||
Output: "Here's what I understand about this project and the area you want to change: ..."
|
||||
|
||||
---
|
||||
|
||||
## Phase 2: Socratic Questioning
|
||||
|
||||
Ask clarifying questions **ONE AT A TIME** via AskUserQuestion. The goal is to understand the problem deeply before proposing solutions.
|
||||
|
||||
Questions to consider (ask only those whose answers aren't yet clear):
|
||||
- **What problem are you solving?** (user outcome, not technical task)
|
||||
- **Who is affected and how?** (scope of impact)
|
||||
- **What constraints exist?** (time, tech debt, dependencies, team capacity)
|
||||
- **What does success look like?** (measurable criteria)
|
||||
- **What have you already tried or considered?** (avoid re-treading)
|
||||
|
||||
**Smart-skip:** If the user's initial prompt already answers a question, skip it. Only ask questions whose answers aren't yet clear.
|
||||
|
||||
**STOP** after each question. Wait for the response before asking the next.
|
||||
|
||||
**Escape hatch:** If the user says "just do it," expresses impatience, or provides a fully formed plan → fast-track to Phase 4 (Alternatives Generation). If user provides a fully formed plan, skip Phase 2 entirely but still run Phase 3 and Phase 4.
|
||||
|
||||
---
|
||||
|
||||
## Phase 2.5: Related Design Discovery
|
||||
|
||||
After the user states the problem (first question in Phase 2), search existing design docs for keyword overlap.
|
||||
|
||||
Extract 3-5 significant keywords from the user's problem statement and grep across design docs:
|
||||
```bash
|
||||
grep -li "<keyword1>\|<keyword2>\|<keyword3>" ~/.gstack/projects/$SLUG/*-design-*.md 2>/dev/null
|
||||
```
|
||||
|
||||
If matches found, read the matching design docs and surface them:
|
||||
- "FYI: Related design found — '{title}' by {user} on {date} (branch: {branch}). Key overlap: {1-line summary of relevant section}."
|
||||
- Ask via AskUserQuestion: "Should we build on this prior design or start fresh?"
|
||||
|
||||
This enables cross-team discovery — multiple users exploring the same project will see each other's design docs in `~/.gstack/projects/`.
|
||||
|
||||
If no matches found, proceed silently.
|
||||
|
||||
---
|
||||
|
||||
## Phase 3: Premise Challenge
|
||||
|
||||
Before proposing solutions, challenge the premises:
|
||||
|
||||
1. **Is this the right problem?** Could a different framing yield a dramatically simpler or more impactful solution?
|
||||
2. **What happens if we do nothing?** Real pain point or hypothetical one?
|
||||
3. **What existing code already partially solves this?** Map existing patterns, utilities, and flows that could be reused.
|
||||
|
||||
Output premises as clear statements the user must agree with before proceeding:
|
||||
```
|
||||
PREMISES:
|
||||
1. [statement] — agree/disagree?
|
||||
2. [statement] — agree/disagree?
|
||||
3. [statement] — agree/disagree?
|
||||
```
|
||||
|
||||
Use AskUserQuestion to confirm. If the user disagrees with a premise, revise understanding and loop back.
|
||||
|
||||
---
|
||||
|
||||
## Phase 4: Alternatives Generation (MANDATORY)
|
||||
|
||||
Produce 2-3 distinct implementation approaches. This is NOT optional.
|
||||
|
||||
For each approach:
|
||||
```
|
||||
APPROACH A: [Name]
|
||||
Summary: [1-2 sentences]
|
||||
Effort: [S/M/L/XL]
|
||||
Risk: [Low/Med/High]
|
||||
Pros: [2-3 bullets]
|
||||
Cons: [2-3 bullets]
|
||||
Reuses: [existing code/patterns leveraged]
|
||||
|
||||
APPROACH B: [Name]
|
||||
...
|
||||
|
||||
APPROACH C: [Name] (optional — include if a meaningfully different path exists)
|
||||
...
|
||||
```
|
||||
|
||||
Rules:
|
||||
- At least 2 approaches required. 3 preferred for non-trivial designs.
|
||||
- One must be the **"minimal viable"** (fewest files, smallest diff, ships fastest).
|
||||
- One must be the **"ideal architecture"** (best long-term trajectory, most elegant).
|
||||
- One can be **creative/lateral** (unexpected approach, different framing of the problem).
|
||||
|
||||
**RECOMMENDATION:** Choose [X] because [one-line reason].
|
||||
|
||||
Present via AskUserQuestion. Do NOT proceed without user approval of the approach.
|
||||
|
||||
---
|
||||
|
||||
## Phase 5: Design Doc
|
||||
|
||||
Write the design document to the project directory.
|
||||
|
||||
```bash
|
||||
SLUG=$(~/.claude/skills/gstack/browse/bin/remote-slug 2>/dev/null || basename "$(git rev-parse --show-toplevel 2>/dev/null || pwd)")
|
||||
BRANCH=$(git rev-parse --abbrev-ref HEAD 2>/dev/null | tr '/' '-' || echo 'no-branch')
|
||||
USER=$(whoami)
|
||||
DATETIME=$(date +%Y%m%d-%H%M%S)
|
||||
mkdir -p ~/.gstack/projects/$SLUG
|
||||
```
|
||||
|
||||
**Design lineage:** Before writing, check for existing design docs on this branch:
|
||||
```bash
|
||||
PRIOR=$(ls -t ~/.gstack/projects/$SLUG/*-$BRANCH-design-*.md 2>/dev/null | head -1)
|
||||
```
|
||||
If `$PRIOR` exists, the new doc gets a `Supersedes:` field referencing it. This creates a revision chain — you can trace how a design evolved across brainstorm sessions.
|
||||
|
||||
Write to `~/.gstack/projects/{slug}/{user}-{branch}-design-{datetime}.md`:
|
||||
|
||||
```markdown
|
||||
# Design: {title}
|
||||
|
||||
Generated by /brainstorm on {date}
|
||||
Branch: {branch}
|
||||
Repo: {owner/repo}
|
||||
Status: DRAFT
|
||||
Supersedes: {prior filename — omit this line if first design on this branch}
|
||||
|
||||
## Problem Statement
|
||||
{from Phase 2}
|
||||
|
||||
## Constraints
|
||||
{from Phase 2}
|
||||
|
||||
## Premises
|
||||
{from Phase 3}
|
||||
|
||||
## Approaches Considered
|
||||
### Approach A: {name}
|
||||
{from Phase 4}
|
||||
### Approach B: {name}
|
||||
{from Phase 4}
|
||||
|
||||
## Recommended Approach
|
||||
{chosen approach with rationale}
|
||||
|
||||
## Open Questions
|
||||
{any unresolved questions from the brainstorm}
|
||||
|
||||
## Success Criteria
|
||||
{measurable criteria from Phase 2}
|
||||
|
||||
## Dependencies
|
||||
{blockers, prerequisites, related work}
|
||||
```
|
||||
|
||||
Present the design doc to the user via AskUserQuestion:
|
||||
- A) Approve — mark Status: APPROVED and proceed to handoff
|
||||
- B) Revise — specify which sections need changes (loop back to revise those sections)
|
||||
- C) Start over — return to Phase 2
|
||||
|
||||
---
|
||||
|
||||
## Phase 6: Handoff
|
||||
|
||||
Once the design doc is APPROVED, suggest the next step:
|
||||
|
||||
- **`/plan-ceo-review`** for ambitious features (EXPANSION mode) — rethink the problem, find the 10-star product
|
||||
- **`/plan-eng-review`** for well-scoped implementation planning — lock in architecture, tests, edge cases
|
||||
- **`/plan-design-review`** for visual/UX design review (coming soon)
|
||||
|
||||
The design doc at `~/.gstack/projects/` is automatically discoverable by downstream skills — they will read it during their pre-review system audit.
|
||||
|
||||
---
|
||||
|
||||
## Important Rules
|
||||
|
||||
- **Never start implementation.** This skill produces design docs, not code. Not even scaffolding.
|
||||
- **Questions ONE AT A TIME.** Never batch multiple questions into one AskUserQuestion.
|
||||
- **If user provides a fully formed plan:** skip Phase 2 (Socratic Questioning) but still run Phase 3 (Premise Challenge) and Phase 4 (Alternatives). Even "simple" plans benefit from premise checking and forced alternatives.
|
||||
- **Completion status:**
|
||||
- DONE — design doc APPROVED
|
||||
- DONE_WITH_CONCERNS — design doc approved but with open questions listed
|
||||
- NEEDS_CONTEXT — user left questions unanswered, design incomplete

- One must be the **"ideal architecture"** (best long-term trajectory, most elegant).
|
||||
- One can be **creative/lateral** (unexpected approach, different framing of the problem).
|
||||
|
||||
**RECOMMENDATION:** Choose [X] because [one-line reason].
|
||||
|
||||
Present via AskUserQuestion. Do NOT proceed without user approval of the approach.
|
||||
|
||||
---
|
||||
|
||||
## Phase 5: Design Doc
|
||||
|
||||
Write the design document to the project directory.
|
||||
|
||||
```bash
|
||||
SLUG=$(~/.claude/skills/gstack/browse/bin/remote-slug 2>/dev/null || basename "$(git rev-parse --show-toplevel 2>/dev/null || pwd)")
|
||||
BRANCH=$(git rev-parse --abbrev-ref HEAD 2>/dev/null | tr '/' '-' || echo 'no-branch')
|
||||
USER=$(whoami)
|
||||
DATETIME=$(date +%Y%m%d-%H%M%S)
|
||||
mkdir -p ~/.gstack/projects/$SLUG
|
||||
```
|
||||
|
||||
**Design lineage:** Before writing, check for existing design docs on this branch:
|
||||
```bash
|
||||
PRIOR=$(ls -t ~/.gstack/projects/$SLUG/*-$BRANCH-design-*.md 2>/dev/null | head -1)
|
||||
```
|
||||
If `$PRIOR` exists, the new doc gets a `Supersedes:` field referencing it. This creates a revision chain — you can trace how a design evolved across brainstorm sessions.
|
||||
|
||||
Write to `~/.gstack/projects/{slug}/{user}-{branch}-design-{datetime}.md`:
|
||||
|
||||
```markdown
|
||||
# Design: {title}
|
||||
|
||||
Generated by /brainstorm on {date}
|
||||
Branch: {branch}
|
||||
Repo: {owner/repo}
|
||||
Status: DRAFT
|
||||
Supersedes: {prior filename — omit this line if first design on this branch}
|
||||
|
||||
## Problem Statement
|
||||
{from Phase 2}
|
||||
|
||||
## Constraints
|
||||
{from Phase 2}
|
||||
|
||||
## Premises
|
||||
{from Phase 3}
|
||||
|
||||
## Approaches Considered
|
||||
### Approach A: {name}
|
||||
{from Phase 4}
|
||||
### Approach B: {name}
|
||||
{from Phase 4}
|
||||
|
||||
## Recommended Approach
|
||||
{chosen approach with rationale}
|
||||
|
||||
## Open Questions
|
||||
{any unresolved questions from the brainstorm}
|
||||
|
||||
## Success Criteria
|
||||
{measurable criteria from Phase 2}
|
||||
|
||||
## Dependencies
|
||||
{blockers, prerequisites, related work}
|
||||
```
|
||||
|
||||
Present the design doc to the user via AskUserQuestion:
|
||||
- A) Approve — mark Status: APPROVED and proceed to handoff
|
||||
- B) Revise — specify which sections need changes (loop back to revise those sections)
|
||||
- C) Start over — return to Phase 2
|
||||
|
||||
---
|
||||
|
||||
## Phase 6: Handoff
|
||||
|
||||
Once the design doc is APPROVED, suggest the next step:
|
||||
|
||||
- **`/plan-ceo-review`** for ambitious features (EXPANSION mode) — rethink the problem, find the 10-star product
|
||||
- **`/plan-eng-review`** for well-scoped implementation planning — lock in architecture, tests, edge cases
|
||||
- **`/plan-design-review`** for visual/UX design review (coming soon)
|
||||
|
||||
The design doc at `~/.gstack/projects/` is automatically discoverable by downstream skills — they will read it during their pre-review system audit.
|
||||
|
||||
---
|
||||
|
||||
## Important Rules
|
||||
|
||||
- **Never start implementation.** This skill produces design docs, not code. Not even scaffolding.
|
||||
- **Questions ONE AT A TIME.** Never batch multiple questions into one AskUserQuestion.
|
||||
- **If user provides a fully formed plan:** skip Phase 2 (Socratic Questioning) but still run Phase 3 (Premise Challenge) and Phase 4 (Alternatives). Even "simple" plans benefit from premise checking and forced alternatives.
|
||||
- **Completion status:**
|
||||
- DONE — design doc APPROVED
|
||||
- DONE_WITH_CONCERNS — design doc approved but with open questions listed
|
||||
- NEEDS_CONTEXT — user left questions unanswered, design incomplete

## Preamble (run first)
|
||||
|
||||
```bash
|

_UPD=$(~/.claude/skills/gstack/bin/gstack-update-check 2>/dev/null || .claude/skills/gstack/bin/gstack-update-check 2>/dev/null || true)

||||
[ -n "$_UPD" ] && echo "$_UPD" || true
|

touch ~/.gstack/sessions/"$PPID"
|
||||

|

|
||||
_CONTRIB=$(~/.claude/skills/gstack/bin/gstack-config get gstack_contributor 2>/dev/null || true)
|
||||
```
|
||||
|
||||
If output shows `UPGRADE_AVAILABLE <old> <new>`: read `~/.claude/skills/gstack/gstack-upgrade/SKILL.md` and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If `JUST_UPGRADED <from> <to>`: tell user "Running gstack v{to} (just updated!)" and continue.
|
||||
|
||||
## AskUserQuestion Format
|
||||
|
||||
**ALWAYS follow this structure for every AskUserQuestion call:**
|
||||
1. Context: project name, current branch, what we're working on (1-2 sentences)
|
||||
2. The specific question or decision point
|
||||
3. `RECOMMENDATION: Choose [X] because [one-line reason]`
|
||||
4. Lettered options: `A) ... B) ... C) ...`
|
||||
|
||||
If `_SESSIONS` is 3 or more: the user is juggling multiple gstack sessions and context-switching heavily. **ELI16 mode** — they may not remember what this conversation is about. Every AskUserQuestion MUST re-ground them: state the project, the branch, the current plan/task, then the specific problem, THEN the recommendation and options. Be extra clear and self-contained — assume they haven't looked at this window in 20 minutes.
|
||||
|
||||
Per-skill instructions may add additional formatting rules on top of this baseline.
|
||||
|
||||
## Contributor Mode
|
||||
|
||||
If `_CONTRIB` is `true`: you are in **contributor mode**. When you hit friction with **gstack itself** (not the user's app), file a field report. Think: "hey, I was trying to do X with gstack and it didn't work / was confusing / was annoying. Here's what happened."
|
||||
|
||||
**gstack issues:** browse command fails/wrong output, snapshot missing elements, skill instructions unclear or misleading, binary crash/hang, unhelpful error message, any rough edge or annoyance — even minor stuff.
|
||||
**NOT gstack issues:** user's app bugs, network errors to user's URL, auth failures on user's site.
|
||||
|
||||
**To file:** write `~/.gstack/contributor-logs/{slug}.md` with this structure:
|
||||
|
||||
```
|
||||
# {Title}
|
||||
|
||||
Hey gstack team — ran into this while using /{skill-name}:
|
||||
|
||||
**What I was trying to do:** {what the user/agent was attempting}
|
||||
**What happened instead:** {what actually happened}
|
||||
**How annoying (1-5):** {1=meh, 3=friction, 5=blocker}
|
||||
|
||||
## Steps to reproduce
|
||||
1. {step}
|
||||
|
||||
## Raw output
|
||||
(wrap any error messages or unexpected output in a markdown code block)
|
||||
|
||||
**Date:** {YYYY-MM-DD} | **Version:** {gstack version} | **Skill:** /{skill}
|
||||
```
|
||||
|
||||
Then run: `mkdir -p ~/.gstack/contributor-logs && open ~/.gstack/contributor-logs/{slug}.md`
|
||||
|
||||
Slug: lowercase, hyphens, max 60 chars (e.g. `browse-snapshot-ref-gap`). Skip if file already exists. Max 3 reports per session. File inline and continue — don't stop the workflow. Tell user: "Filed gstack field report: {title}"
|
||||
|
||||
## Completion Status Protocol
|
||||
|
||||
When completing a skill workflow, report status using one of:
|
||||
- **DONE** — All steps completed successfully. Evidence provided for each claim.
|
||||
- **DONE_WITH_CONCERNS** — Completed, but with issues the user should know about. List each concern.
|
||||
- **BLOCKED** — Cannot proceed. State what is blocking and what was tried.
|
||||
- **NEEDS_CONTEXT** — Missing information required to continue. State exactly what you need.
|
||||
|
||||
### Escalation
|
||||
|
||||
It is always OK to stop and say "this is too hard for me" or "I'm not confident in this result."
|
||||
|
||||
Bad work is worse than no work. You will not be penalized for escalating.
|
||||
- If you have attempted a task 3 times without success, STOP and escalate.
|
||||
- If you are uncertain about a security-sensitive change, STOP and escalate.
|
||||
- If the scope of work exceeds what you can verify, STOP and escalate.
|
||||
|
||||
Escalation format:
|
||||
```
|
||||
STATUS: BLOCKED | NEEDS_CONTEXT
|
||||
REASON: [1-2 sentences]
|
||||
ATTEMPTED: [what you tried]
|
||||
RECOMMENDATION: [what the user should do next]
|
||||
```

# Systematic Debugging
|
||||
|
||||
## Iron Law
|
||||
|
||||
**NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST.**
|
||||
|
||||
Fixing symptoms creates whack-a-mole debugging. Every fix that doesn't address root cause makes the next bug harder to find. Find the root cause, then fix it.
|
||||
|
||||
---
|
||||
|
||||
## Phase 1: Root Cause Investigation
|
||||
|
||||
Gather context before forming any hypothesis.
|
||||
|
||||
1. **Collect symptoms:** Read the error messages, stack traces, and reproduction steps. If the user hasn't provided enough context, ask ONE question at a time via AskUserQuestion.
|
||||
|
||||
2. **Read the code:** Trace the code path from the symptom back to potential causes. Use Grep to find all references, Read to understand the logic.
|
||||
|
||||
3. **Check recent changes:**
|
||||
```bash
|
||||
git log --oneline -20 -- <affected-files>
|
||||
```
|
||||
Was this working before? What changed? A regression means the root cause is in the diff.
|
||||
|
||||
4. **Reproduce:** Can you trigger the bug deterministically? If not, gather more evidence before proceeding.
|
||||
|
||||
Output: **"Root cause hypothesis: ..."** — a specific, testable claim about what is wrong and why.
|
||||
|
||||
---
|
||||
|
||||
## Phase 2: Pattern Analysis
|
||||
|
||||
Check if this bug matches a known pattern:
|
||||
|
||||
| Pattern | Signature | Where to look |
|
||||
|---------|-----------|---------------|
|
||||
| Race condition | Intermittent, timing-dependent | Concurrent access to shared state |
|
||||
| Nil/null propagation | NoMethodError, TypeError | Missing guards on optional values |
|
||||
| State corruption | Inconsistent data, partial updates | Transactions, callbacks, hooks |
|
||||
| Integration failure | Timeout, unexpected response | External API calls, service boundaries |
|
||||
| Configuration drift | Works locally, fails in staging/prod | Env vars, feature flags, DB state |
|
||||
| Stale cache | Shows old data, fixes on cache clear | Redis, CDN, browser cache, Turbo |
|
||||
|
||||
Also check:
|
||||
- `TODOS.md` for related known issues
|
||||
- `git log` for prior fixes in the same area — **recurring bugs in the same files are an architectural smell**, not a coincidence
|
||||
|
||||
---
|
||||
|
||||
## Phase 3: Hypothesis Testing
|
||||
|
||||
Before writing ANY fix, verify your hypothesis.
|
||||
|
||||
1. **Confirm the hypothesis:** Add a temporary log statement, assertion, or debug output at the suspected root cause. Run the reproduction. Does the evidence match?
|
||||
|
||||
2. **If the hypothesis is wrong:** Return to Phase 1. Gather more evidence. Do not guess.
|
||||
|
||||
3. **3-strike rule:** If 3 hypotheses fail, **STOP**. Use AskUserQuestion:
|
||||
```
|
||||
3 hypotheses tested, none match. This may be an architectural issue
|
||||
rather than a simple bug.
|
||||
|
||||
A) Continue investigating — I have a new hypothesis: [describe]
|
||||
B) Escalate for human review — this needs someone who knows the system
|
||||
C) Add logging and wait — instrument the area and catch it next time
|
||||
```
|
||||
|
||||
**Red flags** — if you see any of these, slow down:
|
||||
- "Quick fix for now" — there is no "for now." Fix it right or escalate.
|
||||
- Proposing a fix before tracing data flow — you're guessing.
|
||||
- Each fix reveals a new problem elsewhere — wrong layer, not wrong code.
|
||||
|
||||
---
|
||||
|
||||
## Phase 4: Implementation
|
||||
|
||||
Once root cause is confirmed:
|
||||
|
||||
1. **Fix the root cause, not the symptom.** The smallest change that eliminates the actual problem.
|
||||
|
||||
2. **Minimal diff:** Fewest files touched, fewest lines changed. Resist the urge to refactor adjacent code.
|
||||
|
||||
3. **Write a regression test** that:
|
||||
- **Fails** without the fix (proves the test is meaningful)
|
||||
- **Passes** with the fix (proves the fix works)
|
||||
|
||||
4. **Run the full test suite.** Paste the output. No regressions allowed.
|
||||
|
||||
5. **If the fix touches >5 files:** Use AskUserQuestion to flag the blast radius:
|
||||
```
|
||||
This fix touches N files. That's a large blast radius for a bug fix.
|
||||
A) Proceed — the root cause genuinely spans these files
|
||||
B) Split — fix the critical path now, defer the rest
|
||||
C) Rethink — maybe there's a more targeted approach
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Phase 5: Verification & Report
|
||||
|
||||
**Fresh verification:** Reproduce the original bug scenario and confirm it's fixed. This is not optional.
|
||||
|
||||
Run the test suite and paste the output.
|
||||
|
||||
Output a structured debug report:
|
||||
```
|
||||
DEBUG REPORT
|
||||
════════════════════════════════════════
|
||||
Symptom: [what the user observed]
|
||||
Root cause: [what was actually wrong]
|
||||
Fix: [what was changed, with file:line references]
|
||||
Evidence: [test output, reproduction attempt showing fix works]
|
||||
Regression test: [file:line of the new test]
|
||||
Related: [TODOS.md items, prior bugs in same area, architectural notes]
|
||||
Status: DONE | DONE_WITH_CONCERNS | BLOCKED
|
||||
════════════════════════════════════════
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Important Rules
|
||||
|
||||
- **3+ failed fix attempts → STOP and question the architecture.** Wrong architecture, not failed hypothesis.
|
||||
- **Never apply a fix you cannot verify.** If you can't reproduce and confirm, don't ship it.
|
||||
- **Never say "this should fix it."** Verify and prove it. Run the tests.
|
||||
- **If fix touches >5 files → AskUserQuestion** about blast radius before proceeding.
|
||||
- **Completion status:**
|
||||
- DONE — root cause found, fix applied, regression test written, all tests pass
|
||||
- DONE_WITH_CONCERNS — fixed but cannot fully verify (e.g., intermittent bug, requires staging)
|
||||
- BLOCKED — root cause unclear after investigation, escalated
