readmd-code-analysis

A factual analysis of source code or configuration. It explains how the code works, what it depends on, how data moves through it, and where failures or risks may occur.

In plain words
What is it for?
Use it to inspect logic, settings, dependencies, data flow, failure modes, and security or maintenance concerns in supplied code.
Why use it?
It gives developers a structured review without treating guesses as confirmed bugs or inventing execution results.

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

readmd-code-analysis 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 2d 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 it actually says

Analyze the supplied source in {{language}}. Describe its core logic, key configuration, dependencies, data flow, failure modes and security or maintenance risks. Cite exact identifiers or short excerpts from the source when useful. Never invent execution results or vulnerabilities; distinguish evidence from hypotheses.

Files

What ships with it

1 file 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.

Changes

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.
