What is update-codemaps?

A command that scans a codebase and updates architecture maps: concise documents showing the project’s structure, dependencies, backend, frontend, and data model.

Use it to refresh architecture, backend, frontend, and data documentation, review structural changes, and record codemap freshness and differences.

It keeps architecture documentation aligned with the source code and shows how much the structure changed since the previous version.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00197
Opus 5.5	$0.00000	$0.00079
Sonnet 5.5	$0.00000	$0.00039
Haiku 4.5	$0.00000	$0.00020

Security

Grade A, and why

update-codemaps 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 2mo 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.

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.
