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-4-7
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

Self-Review Opt-In (#796 / vision-013)

When BB reviews a PR that modifies BB itself — or any other framework file under .claude/, grimoires/, .beads/, etc. — the Loa-aware filter normally strips those files from the review payload before the multi-model pass. This is correct for code-PR reviews (no review noise from grimoire side-effects) but inverts on self-modifying PRs (the framework files ARE the substance).

To opt a single PR into self-review (framework files visible to all reviewer models), apply the label:

bridgebuilder:self-review

When detected, BB:

• Skips the LOA framework exclusion for that PR's review pass — .claude/, grimoires/, .beads/ files become reviewable
• Continues to honor .reviewignore operator-curated patterns (BR-003 / BB-001-security): secrets/, vendor/, private-doc patterns in your repo's .reviewignore still exclude their matches under self-review. The label is an Allow on framework files, NOT a global Deny suppressor.
• Surfaces a banner in the review output:
  • With .reviewignore user patterns: [Loa-aware: self-review opt-in active — framework files included; .reviewignore (N user patterns) still honored (vision-013 / #796)]
  • Without: [Loa-aware: self-review opt-in active — framework files included (vision-013 / #796)]
• Sets truncated.selfReviewActive: true on the typed TruncationResult (downstream consumers — cache key, audit logs, future analyzers — read this field; never substring-match the banner prose, BB-797-001)
• Leaves the global config (loaAware) untouched — the opt-in is per-PR, not workspace-wide
• The Pass 1 cache key includes selfReview as a distinct dimension, so toggling the label on a PR with unchanged headSha produces a fresh review (BB-003-cache)

Use this for: bridgebuilder TS adapter changes, cycle-planning PRs (PRD/SDD/sprint), construct manifest changes, anything where the framework artifacts ARE the diff. The label is a single source of truth (constant SELF_REVIEW_LABEL in core/truncation.ts); substring matches like bridgebuilder:self-review-extra do NOT trigger.

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]
