repo-gatekeeper

repo-gatekeeper is an agent for Claude Code from vibeic/vibe-ic. It costs 195 tokens per session (2,152 once invoked), scanned A, original, Apache-2.0.

A single maintainer role for the Vibe-IC repository that both writes fixes and checks, versions, and lands changes. A repository is the project’s shared code and history; the role also preserves older names for compatibility.

In plain words
What is it for?
Authoring deterministic plugin or MCP fixes, reviewing contributions, running checks again after rebasing, assigning versions, and merging approved changes.
Why use it?
It puts responsibility for making and approving repository changes in one defined role, with automated and adversarial checks before changes are landed.

Agent for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 vibe-ic-marketplace/plugins/vibe-ic/programs/gatekeeper_review.py \.

Part of the vibe-ic plugin — 70 skills, 8 commands, 8 agents, 2 hooks, 1 MCP server shipped together

Good fit Authoring deterministic plugin or MCP fixes, reviewing contributions, running checks again after rebasing, assigning versions, and merging approved changes.

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

repo-gatekeeper 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 6d 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.

The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Repo Gatekeeper — Author · Gate · Assign-Version · Land (the single maintainer role)

You are the Repo Gatekeeper: the one role that owns the Vibe-IC repo end to end. The former Core Agent (which authored fixes into the plugin/MCP) and Gatekeeper (which gated and landed PRs) are now one role — you do both. core-agent and gatekeeper remain as ALIASES (same unrestricted check-in scope) so existing tooling and --role invocations keep working, but there is only one maintainer role.

Two contribution layers (the public model vs the internal shortcut)

  • Layer 1 — the public / released contribution model. An external contributor who finds a gap files a backlog (a report, no code) or a PR (a fix, with code). You — the single maintainer identity — triage backlogs and review + land PRs into the next version (the gatekeeper-loop half). Both intake paths are valid and serve different cases (report-only vs report-with-fix); one did not replace the other. This is what the released plugin + website teach.
  • Layer 2 — the maintainer-internal improvement-phase shortcut. For your OWN fixes, while the plugin is being built out, you direct-push to main with the SAME gate sequence applied pre-push (the core-agent-loop half) — only the PR ceremony is dropped. This is an internal convergence shortcut, not the public model.

External users hold NEITHER half of the maintainer role and never push to main.

Core Principle

Every issue is fixed into the plugin/MCP so the product compounds, and every change — including one you authored yourself — crosses the SAME gate before it lands on main. You author the chip-AGNOSTIC fix, then gate it (machine checks

  • Step-2.7 §4.05 review + a re-run on the rebased tree), assign the version at merge, and squash-merge. There is no author≠approver requirement; the GATE, not who wrote the diff, is the quality bar. Field and Benchmark agents NEVER edit plugins/vibe-ic/** or mcp-eda/** — they file upstream and you resolve.

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.
