calibrate-claude-md

calibrate-claude-md is a skill for Claude Code from odere-pro/claude-calibration. It costs 185 tokens per session (1,365 once invoked), scanned A, original, MIT.

A checker for CLAUDE.md instruction files, including project, user, and nested files. These files give Claude coding-agent rules for working in a codebase.

In plain words
What is it for?
Use it to audit instruction files, review reported issues, suggest corrections, or apply approved fixes one at a time.
Why use it?
It finds problems such as committed secrets, oversized files, vague rules, deep imports, and contradictions between instruction files.

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

calibrate-claude-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 11d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/enumerate.sh, scripts/lint.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

calibrate-claude-md — per-feature bundle

You audit and tune CLAUDE.md / CLAUDE.local.md / nested **/CLAUDE.md. You receive one of two kinds of work:

  • Direct invocation (/claude-calibration:calibrate-claude-md) — audit everything, report findings, propose fixes inline. The user drives the conversation.
  • Dispatch from the calibrator — one approved plan row at a time, applied surgically.

In both cases the workflow is the same; only the framing differs.

1. Enumerate

bash <BUNDLE>/scripts/enumerate.sh "$PROJECT_DIR"

Yields TSV scope\tpath. Scope is user (~/CLAUDE.md, ~/.claude/CLAUDE.md), project (<PROJECT_DIR>/CLAUDE.md, <PROJECT_DIR>/CLAUDE.local.md), or nested (any other <PROJECT_DIR>/**/CLAUDE.md).

2. Lint

bash <BUNDLE>/scripts/lint.sh <path …>

Yields TSV path\tsignature\tseverity\tdetail. The signatures this bundle owns (see reference.md):

  • claude-md:secret-leak (CRITICAL)
  • claude-md:over-200 (MEDIUM)
  • claude-md:over-400 (HIGH)
  • claude-md:vague-rules (MEDIUM)
  • claude-md:no-agents-md-import (LOW)
  • claude-md:imports-too-deep (HIGH)
  • claude-md:contradicts-nested (MEDIUM)
  • claude-md:must-rule-with-no-hook (MEDIUM)
  • claude-md:restated-readme (LOW)

3. Fix — kind: edit rows

For each finding, the remediation pattern is in examples/<case>/:

  • claude-md:over-200 / claude-md:over-400examples/over-200/{before,after}.md (trim the CLAUDE.md; move topic blocks into .claude/rules/<topic>.md with paths: — companion work in calibrate-rules).
  • claude-md:secret-leak → remove the secret, rotate it, move sensitive values to CLAUDE.local.md (git-ignored) or .env.
  • claude-md:vague-rules → replace aspirational verbs with concrete, verifiable rules; recurrence promotes to a .claude/rules/conventions.md (companion work in calibrate-rules).
  • claude-md:must-rule-with-no-hook → either soften the wording or add the matching enforcement hook (companion work in calibrate-hooks).
  • claude-md:no-agents-md-import → add @AGENTS.md near the top of CLAUDE.md.
  • claude-md:imports-too-deep → flatten the import chain; collapse intermediate hops.
  • claude-md:contradicts-nested → reconcile: pick a canonical statement and link the others.
  • claude-md:restated-readme → replace duplicated content with @README.md or a link.

What ships with it

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.

calibrate-claude-md is a skill published in the GitHub repository odere-pro/claude-calibration (1 stars, last pushed 1mo ago), licensed MIT. It adds 185 tokens to every session and 1,365 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

Spec a ticket before it is dispatched. Brainstorms it, decides everything it can recommend an answer for, asks a present human about the little that survives, and leaves the spec, the decisions and anything still open as one ticket comment. No worktree, no branch, no pull request, and the ticket stays where it was.
