Repository Configuration

Reference skill loaded into agent context via skills: repo-config. Provides patterns for dynamic repository detection so agents never hardcode branch names, repo identifiers, or conventions.

Core Commands

Default Branch

Used by code-reviewer for diff base and convention-checker for commit range:

DEFAULT_BRANCH=$(gh repo view --json defaultBranchRef --jq '.defaultBranchRef.name')

# Usage in agents:
git diff origin/$DEFAULT_BRANCH..HEAD           # code-reviewer
git log --oneline $DEFAULT_BRANCH..HEAD         # convention-checker

Repository Owner/Name

Used by implementation-planner for GitHub API calls:

REPO=$(gh repo view --json nameWithOwner --jq '.nameWithOwner')

# Usage in agents:
gh api repos/$REPO/issues/$ISSUE_NUMBER/comments
gh api repos/$REPO/pulls/$PR_NUMBER/comments

Combined Fetch

When multiple values are needed, minimize API calls:

gh repo view --json nameWithOwner,defaultBranchRef --jq '{
  repo: .nameWithOwner,
  default_branch: .defaultBranchRef.name
}'

Conventions

Used by convention-checker to validate branch names and commit messages. These defaults are configurable via settings.gh-workflow.json (see conventions.* keys in schema.json). Commands may also override with project-specific conventions from CLAUDE.md — check CLAUDE.md first, then settings, then these defaults.

Branch Naming

Configurable via .conventions.branchPatterns and .conventions.additionalBranchTypes in settings.

Type	Default Pattern	Example
Feature	feature/issue-{N}-{desc}	feature/issue-42-add-login
Fix	fix/issue-{N}-{desc}	fix/issue-13-typo
Docs	docs/issue-{N}-{desc}	docs/issue-7-readme

Additional branch types can be added via .conventions.additionalBranchTypes (e.g., {"refactor": "refactor/issue-{N}-{desc}", "chore": "chore/issue-{N}-{desc}"}).

Commit Prefixes

Configurable via .conventions.commitTypes in settings.

Prefix	Usage
feat:	New features
fix:	Bug fixes
docs:	Documentation
refactor:	Code refactoring
test:	Test changes
chore:	Maintenance

Detecting Project-Specific Conventions

# Check CLAUDE.md first (preferred source)
CLAUDE_MD=""
[ -f ".claude/CLAUDE.md" ] && CLAUDE_MD=".claude/CLAUDE.md"
[ -z "$CLAUDE_MD" ] && [ -f "CLAUDE.md" ] && CLAUDE_MD="CLAUDE.md"
[ -n "$CLAUDE_MD" ] && grep -A5 -E "(Branch|Commit|Convention)" "$CLAUDE_MD" 2>/dev/null

# Fall back to inferring from existing patterns
git for-each-ref --sort=-committerdate --format='%(refname:short)' refs/remotes/origin/ | head -10
git log --oneline -20

Agent Integration

This skill is loaded into agent context via skills: repo-config in agent frontmatter:

Agent	What it needs	Key commands
code-reviewer	DEFAULT_BRANCH for diff base	git diff origin/$DEFAULT_BRANCH..HEAD
convention-checker	DEFAULT_BRANCH for commit range, conventions for validation	git log $DEFAULT_BRANCH..HEAD, branch/commit patterns
implementation-planner	REPO for GitHub API calls	gh api repos/$REPO/issues/...
test-runner	Declared but not directly used	—

Error Handling

If gh commands fail:

Check	Command	Fix
Authentication	gh auth status	Run gh auth login
Git repository	git rev-parse --git-dir	Navigate to a git repo or run git init
GitHub remote	git remote -v	Add with git remote add origin <url>
