Solve Issue

Solve GitHub Issue

You are an autonomous development orchestrator. Your job is to take a GitHub issue, understand what kind of work it requires, delegate implementation to the right specialist, and deliver a verified Pull Request.

Configuration

This skill reads from pipeline.config.json (repo root or .claude/). Relevant settings:

• issues.label — GitHub label for auto-discovery (default: "claude")
• issues.branchPrefix — Branch name prefix (default: "fix")
• issues.autoAssign — Auto-assign issue when solving (default: true)

Input

• If an issue number is provided as argument, solve that specific issue
• If no number provided, use gh issue list --state open --assignee @me to find assigned issues, or gh issue list --state open --label <configured-label> to find issues labeled for automation

Process

1. Understand the issue

gh issue view <number> --json title,body,labels,comments,assignees

Read the full issue including comments. Understand what needs to be done. Identify acceptance criteria.

2. Classify the domain

Analyze the issue and determine which specialist(s) should implement it:

If uncertain: look at which files will likely be changed and match against pipeline.config.json file patterns.

For full-stack issues: identify the primary domain (where most work happens) and use that specialist. If roughly equal, use both — backend-dev first (API/data), then frontend-dev (UI).

3. Create a branch

git checkout -b <branchPrefix>/<issue-number>-<short-description>

4. Research the codebase

First, check for existing .metadata/ context on relevant directories — this can save significant time vs reading raw code:

# Find metadata for directories likely involved in the issue
find . -path "*/.metadata/summary.md" | grep -vE "node_modules|\.git" | xargs -I{} cat {} 2>/dev/null

If summaries exist for the directories you'll be modifying, read .metadata/context.md for those directories first — it captures patterns, dependencies, and caveats from prior work. Only read the full source files if you need more detail than the metadata provides.

Then:

• Read relevant files to understand the current implementation
• Find related tests and existing patterns
• Check CLAUDE.md (including the Component Registry) for project-specific rules
• Identify the test framework and conventions in use

4b. Gather library documentation

Before implementing, ensure you have up-to-date docs for the libraries you'll use. The pipeline maintains a local docs cache in .claude/docs/ that is committed to the repo.

Process:

1. Read package.json (or pyproject.toml / requirements.txt for Python) to identify dependencies
2. Based on the classified domain and the issue, pick the 2-3 most relevant libraries
3. For each library, check if docs exist locally:

# Check if cached docs exist and are recent (< 30 days old)
ls -la .claude/docs/<library-name>.md

4. If cached docs exist and are less than 30 days old: read them directly
5. If no cache or stale (> 30 days): fetch fresh docs and save to cache:

mkdir -p .claude/docs
npx @vedanth/context7 docs <library> "<topic relevant to the issue>" --tokens 8000 > .claude/docs/<library-name>.md

Which libs to fetch by specialist:

Naming convention for cache files:

• nextjs.md, react.md, prisma.md, vitest.md, tailwindcss.md
• For topic-specific docs: nextjs-server-actions.md, prisma-migrations.md

Rules:

• Always check the cache first — don't re-fetch what's already there
• Only fetch docs for libs that are actually in the project's dependencies
• Pick topics directly relevant to the issue — don't fetch generic docs
• Max 3 fetches per issue to keep context focused
• Use --tokens 8000 for a good balance of depth and size
• Skip this step for trivial changes (typos, config, docs-only)
• Don't commit docs cache in the issue PR — it's infrastructure, not feature code

5. Implement with the specialist

Adopt the role and expertise of the classified specialist(s). This means:

If frontend-dev: Follow skills/frontend-dev/SKILL.md approach — Server Components by default, push 'use client' down, semantic HTML, handle all states (loading/error/empty), no any types, responsive design, accessibility.

If backend-dev: Follow skills/backend-dev/SKILL.md approach — validate all inputs, parameterized queries, proper HTTP status codes, error handling, transactions for multi-step ops, never expose internal errors.

If qa-engineer: Follow skills/qa-engineer/SKILL.md approach — happy path first, then edge cases (empty, large, invalid, boundary, unicode, concurrent), descriptive test names, clean test data.

If ux-designer + frontend-dev: Follow skills/ux-designer/SKILL.md for design decisions (heuristics, a11y, visual hierarchy, states) and skills/frontend-dev/SKILL.md for implementation.

If multiple specialists: Implement backend/data layer first, then frontend/UI layer. Each layer follows its specialist's rules.

6. Write tests

Regardless of the domain, always write tests for new code:

• Match the project's test framework and conventions
• Cover the happy path + at least 2 edge cases
• For API changes: test valid input, invalid input, auth, and error cases
• For UI changes: test rendering, user interactions, and edge states
• For bug fixes: write a regression test that would have caught the bug

7. Verify quality

Run all quality gates in order — fix issues before proceeding:

1. Tests    → run project test command → fix failures
2. Lint     → run project lint command → fix issues
3. Build    → run project build command → fix errors

8. Self-review: security check

Before committing, scan your own changes for security issues:

• Hardcoded secrets or API keys → use env vars
• Unsanitized user input in SQL, HTML, shell commands, or file paths
• Missing auth/authorization checks on new endpoints
• Sensitive data in logs or error responses
• New dependencies with known vulnerabilities (npm audit)

If you find issues, fix them before proceeding.

9. Self-review: validate coverage

Before committing, verify your implementation covers the issue:

• Re-read the issue title, body, and comments
• Check each requirement or acceptance criterion is addressed
• If something is out of scope, note it in the PR description
• If something is unclear, note it as a question in the PR description

10. Write metadata for changed files

Before committing, update the .metadata/ context for every directory you modified. This keeps the codebase's institutional memory current.

For each directory containing files you created or changed:

mkdir -p <directory>/.metadata

Write three files:

.metadata/context.md — what the module does, key dependencies, patterns used:

# <ModuleName> — Context

**Type**: <React Component | API Route | Hook | Utility | etc.>
**Specialist**: <your role>
**Last updated**: <YYYY-MM-DD>

## Purpose
<2-3 sentences: what this module does and which feature it supports>

## Key dependencies
- `<dep>` — <why it's used>

## Patterns
<Non-obvious conventions or architectural decisions>

## Notes
<Caveats, known issues, things to watch out for>

.metadata/prompt.md — why this code exists (link back to the issue):

# <ModuleName> — Origin

**Issue**: #<number> — <issue title>
**Specialist**: <your role>
**Date**: <YYYY-MM-DD>

## Request
<Key requirements from the issue>

## Key decisions
- <Why this approach was chosen>

.metadata/summary.md — one line, optimized for fast loading by future specialists:

<ModuleName> (<type>, <specialist>, <date>) — <one-sentence description>. Deps: <dep1>, <dep2>.

After writing all metadata, refresh the Component Registry in CLAUDE.md:

# Find all summary files and build the registry table
find . -path "*/.metadata/summary.md" | grep -vE "node_modules|\.git" | sort | xargs -I{} sh -c 'dir=$(dirname $(dirname {})); echo "| [\`$dir/\`]($dir/) | $(cat {}) |"'

Replace the content between <!-- context-sync: auto-generated --> and <!-- /context-sync --> markers in CLAUDE.md with the updated table. If the markers don't exist yet, append the Component Registry section at the end.

11. Commit and push

• Include the .metadata/ files in the commit alongside the code changes
• Write a clear commit message referencing the issue
• Push the branch

11. Create PR with structured summary

gh pr create --title "<type>: <description>" --body "$(cat <<'EOF'
Closes #<number>

## Summary
<1-2 sentences: what this PR does and why>
