auditing-sibling-projects - SKILL.md Agent Skill

name: auditing-sibling-projects description: Runs cross-repo contract detection and impact analysis on sibling projects in a workspace. Detects schema, route, command, and config changes, traces the dependency graph, and produces an impact report with severity and recommended actions.

Auditing Sibling Projects

When to Use

Before merging changes that affect shared contracts (schemas, routes, configs)
When a provider repo (e.g., CLI) has changed and consumers (e.g., API) need review
During sprint planning to assess cross-repo impact
When the user asks to check impact or audit sibling projects

Prerequisites

A workspace must be configured (.paircoder-workspace.yaml exists)
Projects must declare consumers/consumes relationships
Must be run from within a project directory inside the workspace

Workflow

1. Load Workspace

bpsai-pair workspace status

Verify workspace is configured and all projects are discovered.

2. Check Impact

# Check contract changes since last commit
bpsai-pair workspace check-impact

# Check since a specific commit
bpsai-pair workspace check-impact --since <commit-hash>

# Machine-readable output
bpsai-pair workspace check-impact --json

Review the impact report:

Severity: high (schema/route), medium (command), low (config)
Affected repos: consumers that may need updates
Recommended actions: specific steps for each affected repo

3. Audit a Specific Sibling

# Audit a specific project
bpsai-pair workspace audit <project-name>

# With JSON output
bpsai-pair workspace audit <project-name> --json

# With auto-fix for trivial issues (future)
bpsai-pair workspace audit <project-name> --fix

4. Review and Act

For each recommended action:

Open the affected sibling project
Check the specific files mentioned in the impact report
Update schemas, routes, or configs as needed
Run tests in the sibling project
Create cross-repo tasks if changes are needed

5. Record Results

The audit is automatically recorded in .paircoder-audit.jsonl.

Severity Guide

Level	Change Types	Action Required
High	Schema, Route	Immediate review of all consumers
Medium	Command	Review consumer integrations
Low	Config	Check config compatibility
