Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00082 | $0.01764 |
| Opus 5.5 | $0.00033 | $0.00706 |
| Sonnet 5.5 | $0.00016 | $0.00353 |
| Haiku 4.5 | $0.00008 | $0.00176 |
Grade A, and why
claude-md-improver 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 21d 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.
This is a copy
88% identical to claude-md-improver — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md Improver
Audit, evaluate, and improve CLAUDE.md files across a codebase to ensure Claude Code has optimal project context.
This skill can write to CLAUDE.md files. After presenting a quality report and getting user approval, it updates CLAUDE.md files with targeted improvements.
Workflow
Phase 1: Discovery
Find all CLAUDE.md files in the repository:
find . -name "CLAUDE.md" -o -name ".claude.md" -o -name ".claude.local.md" 2>/dev/null | head -50
File Types & Locations:
| Type | Location | Purpose |
|---|---|---|
| Project root | ./CLAUDE.md |
Primary project context (checked into git, shared with team) |
| Local overrides | ./.claude.local.md |
Personal/local settings (gitignored, not shared) |
| Global defaults | ~/.claude/CLAUDE.md |
User-wide defaults across all projects |
| Package-specific | ./packages/*/CLAUDE.md |
Module-level context in monorepos |
| Subdirectory | Any nested location | Feature/domain-specific context |
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

Fix a broken OpenAPI spec in jentic-public-apis with an OpenAPI Overlay, validate it (spectral lint + idempotency check), and contribute it back via a PR to the community catalog. Falls back to applying the same overlay to the local Jentic registry if the user can't wait for maintainer approval, and closes the loop by…
jentic
Calls third-party APIs through a Jentic One instance — governed, credential-managed access where the agent searches for an operation, inspects it, and executes it through an audited broker that holds the credentials (identity → discover → check access → execute). Applies when the user asks to call an external API or…
