murmur: Skill for Claude Code

.agents/skills/add-ci-gate/SKILL.md

add-ci-gate is a skill for Claude Code, Codex from murmur-io/murmur. It costs 114 tokens per session (1,491 once invoked), scanned A, original, AGPL-3.0.

A procedure for adding or changing a check in Murmur’s continuous-integration gate, the automated checks that run for code changes. It covers ordering, handling missing tools, and testing guardrail hooks.

In plain words
What is it for?
Use it when modifying `scripts/ci.sh`, adding a CI check, or changing a guardrail hook and its self-test.
Why use it?
It keeps checks in one source of truth and avoids making the development feedback loop unnecessarily slow or fragile.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is murmur-io/murmur's own configuration. It tells Claude Code and Codex how to work on murmur 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 murmur configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is MURMUR_CI_SKIP_E2E=1 scripts/agent-resource-run -- bash scripts/ci.sh.

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

add-ci-gate 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 4d 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.

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.
