name: "@tank/bdd-issue-fixer" description: | Resolve GitHub issues using BDD — read the issue, write a behavioral test, confirm it fails (RED), fix the code, confirm it passes (GREEN), open a PR with test + fix as proof. Covers issue triage (bug vs feature vs invalid vs duplicate), issue-to-Gherkin translation, the relentless RED-GREEN fix cycle, fix verification, PR submission with evidence, and related issue detection. Synthesizes Smart/Molak (BDD in Action), Beck (TDD By Example), Nicieja (Writing Great Specifications), SWE-bench (Princeton NLP), and Sweep.dev patterns.

Trigger phrases: "fix this issue", "resolve issue", "fix GitHub issue", "BDD fix", "issue to test", "write test for issue", "red green fix", "triage issue", "duplicate issue", "related issues", "fix and PR", "issue fixer", "auto-fix issue", "resolve bug report"

BDD Issue Fixer

Hard Rules

These are non-negotiable. Violating any of these means the work is wrong.

1. Never weaken a test. When a test fails, the CODE is wrong. Fix the code, not the test. Never skip, mock, or reduce assertion precision.

2. Test behavior, not implementation. The Gherkin scenario captures what the user expects. Write declarative scenarios from the user's perspective, never imperative UI scripts.

3. Iterate until fixed. Try up to 5 different fix strategies. If approach 1 fails, analyze why and try approach 2. Never give up after one attempt. Escalate only after 5 genuine attempts.

4. Not every issue deserves a fix. Triage first. Duplicates, questions, invalid reports, and vague wishlists are not fixable issues. Classify before coding.

5. Document everything. Every fix produces findings, resolutions, and a PR with evidence. The BDD scenario in the PR IS the proof.

Core Workflow

This is the mandatory sequence. Execute in order. Do not skip steps.

1. TRIAGE  →  Read issue, classify, check for duplicates/related
     ↓
2. GHERKIN →  Translate fixable issue into behavioral test
     ↓
3. RED     →  Run test, confirm it fails (bug exists)
     ↓
4. FIX     →  Implement minimal code change
     ↓
5. GREEN?  →  Run test again
     ↓ YES         ↓ NO
6. VERIFY      Back to step 4 (max 5 iterations)
     ↓
7. PR      →  Create PR with test + fix + evidence

Quick-Start

"I have a GitHub issue to fix"

Step	Action
1. Read issue	gh issue view {N} --json title,body,labels,comments
2. Triage	Classify: bug / feature / question / invalid / duplicate. See references/issue-triage.md
3. Check related	Search for duplicates and same-root-cause issues. See references/related-issues.md
4. Write Gherkin	Translate issue into .bdd/features/{domain}/{slug}.feature. See references/issue-to-gherkin.md
5. RED-GREEN cycle	Run test → fix code → run test → repeat until GREEN. See references/red-green-fix-cycle.md
6. Verify	Full suite, no regressions, document findings. See references/fix-verification.md
7. PR	Branch, commit (test, fix, docs), push, create PR. See references/pr-and-git-workflow.md

"The issue seems invalid or incomplete"

Signal	Action	Reference
Can't reproduce	Ask for clarification with template	references/issue-triage.md
User confusion, not a bug	Answer the question, close	references/issue-triage.md
Same as existing issue	Link to original, close as duplicate	references/related-issues.md
Vague wishlist, no criteria	Label "needs-discussion", don't fix	references/issue-triage.md
Requires breaking changes	Escalate to maintainer	references/issue-triage.md

"My fix broke other tests"

Symptom	Fix	Reference
Target test passes but other tests fail	Adjust fix to satisfy both behaviors	references/fix-verification.md
Flaky test fails intermittently	Run 3x — if pre-existing flake, note and move on	references/fix-verification.md
Type/lint errors in changed files	Fix them — never suppress with ts-ignore or rule disabling	references/fix-verification.md

"Multiple issues seem related"

Relationship	Action	Reference
Duplicate (same bug)	Close duplicate, fix canonical	references/related-issues.md
Same root cause	Write Gherkin for ALL, fix root cause once	references/related-issues.md
Blocked by another issue	Fix blocker first	references/related-issues.md
Parent-child	Fix parent, check if child resolves	references/related-issues.md

Decision Trees

Should I fix this issue?

Signal	Decision
Clear bug with repro steps	Fix it
Feature request with acceptance criteria	Fix it
Vague report, can infer expected behavior	Fix it, note assumptions
No expected behavior, can't infer	Ask for clarification
User error or confusion	Answer and close
Duplicate of existing issue	Close, link to original
Requires architectural changes	Escalate, label "needs-design"
Security vulnerability	Private disclosure, do not fix in public PR

Which fix iteration strategy?

Iteration	Strategy
1	Direct fix — most obvious change
2	Root cause analysis — trace the stack trace deeper
3	Broader context — read surrounding code, understand data flow
4	Alternative approach — different algorithm or code path
5	Minimal viable — simplest possible code that makes it work
After 5	Escalate — document all attempts, label "needs-human-review"

Commit and PR Structure

Three atomic commits per fix:

Commit	Content	Message format
1	Gherkin scenario (the failing test)	test: add BDD scenario for #{N}
2	Code fix	fix: {description} (#{N})
3	QA documentation (findings + resolution)	docs: add QA findings for #{N}

PR body must include: the Gherkin scenario, verification results, iteration count, and Fixes #{N} for auto-close. See references/pr-and-git-workflow.md.
