update-codemap

update-codemap is a command for coding agents from AcKeskin/contexture. It costs 13 tokens per session (103 once invoked), scanned A, original, MIT.

A command that scans a project and regenerates a codemap, a document showing the file tree, each area’s purpose, and exported code elements.

In plain words
What is it for?
Use it to create a current .claude/codemap.md file for a project and review the resulting changes.
Why use it?
It refreshes an outdated overview of the codebase so people can understand its structure before making changes.

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

update-codemap 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 yesterday.

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

Run the update-codemap skill on the current project. Overwrites .claude/codemap.md with a fresh scan of the tree, purpose lines, and exports per language.

Full rewrite — no incremental edits. User reviews the resulting diff before committing.

See ~/.claude/skills/update-codemap/SKILL.md for the full procedure, skip rules, and per-language extraction.

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.
