Bridgebuilder — Autonomous PR Review

Prerequisites

• gh CLI installed and authenticated (gh auth status)
• ANTHROPIC_API_KEY environment variable set
• Node.js >= 20.0.0

Usage

/bridgebuilder                          # Review all open PRs on auto-detected repo
/bridgebuilder --dry-run                # Preview reviews without posting
/bridgebuilder --pr 42                  # Review only PR #42
/bridgebuilder --repo owner/repo        # Target specific repo
/bridgebuilder --no-auto-detect         # Skip git remote detection

How It Works

1. Resolves configuration from 5-level precedence: CLI > env > YAML > auto-detect > defaults
2. Detects current repo from git remote -v (unless --no-auto-detect)
3. Fetches open PRs via gh CLI
4. For each PR:
   • Checks if already reviewed (marker: <!-- bridgebuilder-review: {sha} -->)
   • Builds review prompt from persona + truncated diff
   • Calls Anthropic API for review generation
   • Sanitizes output (redacts leaked secrets)
   • Posts review to GitHub (COMMENT or REQUEST_CHANGES)
5. Prints JSON summary: { reviewed, skipped, errors }

Configuration

Set in .loa.config.yaml under bridgebuilder: section, or via environment variables:

Setting	Env Var	Default
repos	BRIDGEBUILDER_REPOS	Auto-detected from git remote
model	BRIDGEBUILDER_MODEL	claude-opus-4-6
dry_run	BRIDGEBUILDER_DRY_RUN	false
max_prs	—	10
max_files_per_pr	—	50
max_diff_bytes	—	100000
max_input_tokens	—	8000
max_output_tokens	—	4000
persona_path	—	grimoires/bridgebuilder/BEAUVOIR.md

Persona

Override the default reviewer persona by creating grimoires/bridgebuilder/BEAUVOIR.md. The default persona reviews across 4 dimensions: Security, Quality, Test Coverage, and Operational Readiness.

Execution

This skill runs entry.sh which invokes the compiled Node.js application:

.claude/skills/bridgebuilder-review/resources/entry.sh [flags]
