What is gsc-tool CLAUDE.md?

A project-specific instruction file for the gsc-tool codebase. It explains the repository, its processing pipeline, and how its engine performs runtime dispatch, where a program chooses which implementation to call while running.

Use it as background when an agent works on the gsc-tool repository, especially its pipeline, engine model, and runtime dispatch code.

It gives a coding agent local context that may not be obvious from the source files alone. The provided information does not describe a standalone tool or additional actions.

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	$0.04870	$0.04870
Opus 5.5	$0.01948	$0.01948
Sonnet 5.5	$0.00974	$0.00974

Security

Grade A, and why

gsc-tool 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 23d 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.
