What is blockwatch CLAUDE.md?

Repository instructions for BlockWatch, a Rust command-line linter. It checks rules written inside HTML-like tags embedded in source-code comments and can inspect all files or only changed lines from a Git diff.

Use them to build and run the CLI, execute all or selected tests, inspect output, format code, run Clippy, and work with fixture-based integration tests or fuzzing.

They explain the project's build, test, formatting, linting, integration-test, and fuzzing routines so code changes can be checked consistently.

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	$0.00003	$0.00003
Opus 5.5	$0.00001	$0.00001
Sonnet 5.5	$0.00001	$0.00001
Haiku 4.5	$0.00000	$0.00000

Security

Grade A, and why

blockwatch CLAUDE.md 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 1mo 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.
