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 | $0.01640 | $0.01640 |
| Opus 5.5 | $0.00656 | $0.00656 |
| Sonnet 5.5 | $0.00328 | $0.00328 |
| Haiku 4.5 | $0.00164 | $0.00164 |
Grade D, and why
cc-agents-kit CLAUDE.md scanned grade D with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 15d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
The same hooks are typically installed in the developing session's own `~/.claude/settings.json`, so they inspect the tool calls used to edit them. Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
Writing documentation or fixtures that *mention* a blocked shape — a download-and-execute pipeline, `rm -rf` on the home directory, a secrets filename — gets blocked when the text passes through `Bash`. How it starts
The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What this repo is
A Claude Code plugin marketplace — not an application. Nothing here is imported or built; the artifacts are shell hooks, skills and their bin/ helpers, plus the JSON manifests that make an installer find them.
Every change is therefore judged on two things: does the manifest still resolve, and does the hook still hold its contract.
Commands
shellcheck plugins/*/hooks/*.sh
(cd plugins/guard-hooks/hooks && for t in *.test.py; do python3 "$t" || exit 1; done)
for t in plugins/*/bin/*.test.py; do python3 "$t" || exit 1; done
python3 plugins/guard-hooks/hooks/<name>.test.py # a single suite
/bin/bash -n plugins/guard-hooks/hooks/<name>.sh # macOS system bash 3.2, not your shell's bash
claude plugin validate plugins/<mod> # a function-hook mod: manifest, module, state contract
claude plugin test plugins/<mod> # runs the mod's *.test.ts against the engine
There is no build, no package manager, and no test framework.
Suites are plain python3 scripts requiring bash and jq, and node for session-to-md.test.py; shellcheck is optional (shellcheck-on-edit.test.py skips its findings checks and asserts the silent no-op instead).
.github/workflows/ci.yml runs the commands above, shellchecks and bash -n-parses every shipped shell script including the extensionless Bash entries under plugins/*/bin/, and checks the manifests, skill frontmatter, private references, bin/ executability, and the demo's quoted guard message.
Layout contract
.claude-plugin/marketplace.json # marketplace.json ONLY — no plugin.json here
plugins/<plugin>/
.claude-plugin/plugin.json # each plugin carries its own manifest
hooks/hooks.json # auto-discovered; commands reference ${CLAUDE_PLUGIN_ROOT}
hooks/*.sh
hooks/*.test.py # beside its hook, never in a tests/ directory
hooks/_optout.py # shared suite helper; leading _ keeps it out of the *.test.py glob
hooks/register.tsx # a function-hook mod's module, named under "modules" in hooks.json
hooks/<mod>.test.ts # its claude plugin test suite, beside the module
types/index.d.ts # a mod's $.state contract, named by "types" in plugin.json
skills/<skill>/SKILL.md # frontmatter name must equal the directory name
bin/<tool> # on PATH while the plugin is enabled; executable, with a shebang
bin/<tool>.test.py # beside its tool, resolved the same way as a hook suite
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.

cc-agents-kit CLAUDE.md is an instructions file published in the GitHub repository AndrewDongminYoo/cc-agents-kit (3 stars, last pushed yesterday), licensed Apache-2.0. It adds 1,640 tokens to every session, about $0.0066 per session on Opus 5.5. A static security scan graded it D with 2 findings (reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
