caldav-mcp: Skill for Claude Code

.agents/skills/review-agents-md/SKILL.md

review-agents-md is a skill for Claude Code, Codex from dominik1001/caldav-mcp. It costs 59 tokens per session (1,163 once invoked), scanned A, original, MIT.

A review guide for AGENTS.md or CLAUDE.md files, which give coding agents project-specific instructions.

In plain words
What is it for?
Use it to audit an agent context file, group findings as delete, rewrite, or add, and report its proposed length and technology coverage.
Why use it?
It identifies instructions that are too long, obvious, missing, or unclear, and proposes specific rewrites without editing the file.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: reads .claude/ paths; mentions CLAUDE.md; installed under .agents/ (shared by several agents).

This is dominik1001/caldav-mcp's own configuration. It tells Claude Code and Codex how to work on caldav-mcp 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 caldav-mcp configures →

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

review-agents-md 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The meta-principle: a context file earns its tokens. Every line must tell the agent something it can't infer from the code, the formatter, or the linter. If a line could be deleted without the agent getting worse, delete it.

Workflow

  1. Read the target file (default: AGENTS.md, then CLAUDE.md at repo root). If both exist, review both.
  2. Evaluate against each rubric below. For every issue, quote the offending lines and propose a concrete rewrite — not just a critique.
  3. Report findings grouped by severity: Cut (delete), Rewrite (fix in place), Add (missing required content).
  4. End with a one-line verdict: total lines now vs. proposed, and whether the tech stack is mentioned.

Do not auto-edit the file unless the user asks. Surface the diff first.

Rubric

Length & signal density

Good: Short and load-bearing. Every line is non-obvious and would change agent behavior if removed. Bad: Long preambles, restated obvious facts ("we use TypeScript"), or generic engineering advice. Flag any file over ~200 lines as suspect and identify the lowest-signal sections to cut.

Non-obvious content only

Good: Conventions, architecture choices, tooling quirks ("we use bun, not node"; "migrations run via make db-migrate, not the ORM CLI"). Bad: Anything derivable from package.json, Cargo.toml, file extensions, or a five-second skim of the repo. Cut it.

Tech stack is mentioned

Good: The language/runtime/framework choices the agent would otherwise guess wrong are mentioned somewhere in the file (e.g., "Bun 1.x runtime, not Node"; "Postgres 16 + Drizzle, not Prisma"). A dedicated ## Tech Stack section is fine but not required — a one-liner near the top works too. Bad: No mention at all of the non-obvious stack choices, so the agent has to infer them from manifests. If missing, propose a short addition drafted from the repo's manifests.

Auto-generated content

Good: Hand-written, curated. Bad: Looks /init-generated — boilerplate headings, file-tree dumps, restatement of package.json scripts. Auto-generated context files measurably reduce success rates. Recommend deletion and replacement with a hand-written file.

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.
