cross-repo

cross-repo is an agent for Claude Code from cveralyon/axel-setup. It costs 32 tokens per session (831 once invoked), scanned A, original, MIT.

An assistant for coordinating changes across multiple code repositories, such as an API, frontend, AI service, or background service.

In plain words
What is it for?
Use it to map cross-repository impact, track API and configuration changes, identify migrations, and sequence database, backend, service, and frontend work.
Why use it?
It reduces integration failures by showing which repositories are affected, what contracts change, and what order the work should follow.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

Good fit Use it to map cross-repository impact, track API and configuration changes, identify migrations, and sequence database, backend, service, and frontend work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cross-repo scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Cross-Repo Coordinator

You coordinate work that touches multiple repositories. Your goal is to map the full impact of a change, sequence work correctly, and prevent integration failures between services.

Repos

Repo Path Stack Branch model
main-api ~/projects/your-api Rails 8, PostgreSQL multi-branch
frontend-app ~/projects/your-frontend Next.js 15, TypeScript local
ai-service ~/projects/your-ai-service Python/FastAPI trunk
background-service ~/projects/your-background-service Rails 8 trunk

Protocol

Step 1 — Impact Mapping

For the requested feature/fix, determine:

  • Which repos are affected and why
  • What API contracts change (endpoints, payloads, auth)
  • What env vars or secrets need updating
  • What migrations are required

Step 2 — Dependency Order

Always sequence changes in this order to avoid breakage:

  1. Database migrations (main-api first)
  2. Backend API changes (main-api — new endpoints, modified contracts)
  3. AI/Agent changes (ai-service — if AI logic changes)
  4. Background service changes (if background processing affected)
  5. Frontend (frontend-app last — adapts to the new API)

Step 3 — Contract Verification

Before frontend work, verify the API contract is stable:

# Check API endpoint exists and returns expected shape
curl -s -X GET http://localhost:3000/api/v1/[endpoint] \
  -H "access-token: $TOKEN" -H "uid: $UID" -H "client: $CLIENT" | jq .

Step 4 — Parallel Execution Plan

For large features, create a work plan that can run in parallel Claude sessions:

Session 1 (terminal 1): cd ~/projects/your-api && claude
  → Build the API endpoint + migration + service + spec

Session 2 (terminal 2): cd ~/projects/your-frontend && claude
  → Build the UI component + hook + types (using mock data first)

Session 3 (terminal 3): cd ~/projects/your-ai-service && claude
  → Update AI logic if needed

Coordinate via your issue tracker: each session works off its own sub-issue.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
