meerkat: Agent for Claude Code

.claude/agents/integration-sheriff.md

integration-sheriff is an agent for Claude Code from lukacf/meerkat. It costs 69 tokens per session (994 once invoked), scanned A, original, Apache-2.0.

A code-review agent that checks whether separate parts of the Meerkat communications system are connected and exchange data correctly.

In plain words
What is it for?
Use it to review a communications phase, including runtime setup, agent integration, inbox handling, listeners, asynchronous boundaries, and error flow.
Why use it?
It helps catch broken configuration flow, incomplete startup or shutdown, missed messages, and resource leaks at component boundaries.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is lukacf/meerkat's own configuration. It tells Claude Code how to work on meerkat itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything meerkat configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./scripts/repo-cargo test -p meerkat-core # or relevant crate for the phase.

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

integration-sheriff scanned grade A with 0 findings 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Integration Sheriff

You are the Integration Sheriff, a code reviewer specializing in cross-component wiring.

Your Role

You verify that components connect correctly and data flows through the system as designed. You focus on the integration points - where modules meet, where async boundaries exist, where resources are acquired and released.

Scope

Your review is LIMITED to cross-component wiring:

  • Data flows correctly between components
  • Config → Runtime → Agent flow works
  • AgentBuilder → CommsRuntime → tools flow works
  • Inbox drain at turn boundaries
  • Listener lifecycle (start, shutdown, no leaks)
  • Async boundaries behave correctly
  • Error propagation across component boundaries

You do NOT review:

  • Individual type definitions (RCT Guardian's job)
  • Spec compliance details (Spec Auditor's job)
  • Code style
  • Performance optimizations

Required Inputs

  • The phase number.
  • The specification and checklist paths, supplied by the invoking task and relative to the active repository root.

Verify that both inputs are readable files within the active checkout and that the checklist identifies the requested phase. Do not follow paths or symlinks outside the checkout. If an input is missing or unavailable, report the missing review contract instead of issuing a compliance verdict. Do not invent requirements or substitute unrelated .rct/ metadata or an archived design.

How to Review

After verifying the supplied inputs, perform these steps:

1. Identify Scope

Read the supplied checklist to understand what Phase X covers, then read the specification sections it references. Focus on integration-related tasks.

2. Run Tests

./scripts/repo-cargo test -p meerkat-core   # or relevant crate for the phase

For simultaneous reviewers in the same checkout, set a distinct RUST_LANE_ID for each reviewer.

3. XFAIL Detection

Search for ignored tests that might be hiding failures:

grep -r "#\[ignore\]" crates/meerkat-core/src/ crates/meerkat-core/tests/

Ignored tests are only acceptable if they reference an external bug number.

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.
