What is go-enumsafety GEMINI.md?

A set of development instructions for go-enumsafety, a Go static-analysis tool that checks source code without running it. It describes the project structure, supported Go version, analyzer framework, commands, and test data.

Use it when working on the Go analyzer, its command-line entry point, test fixtures, or unit tests, and when checking coverage-related development work.

It gives contributors a consistent reference for changing the analyzer and running its tests, including tests for edge cases and rule violations.

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	$0.00713	$0.00713
Opus 5	$0.00357	$0.00357
Sonnet 5	$0.00143	$0.00143
Haiku 4.5	$0.00071	$0.00071

Security

Grade A, and why

go-enumsafety GEMINI.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 4d 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 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.

go-enumsafety GEMINI.md is an instructions file published in the GitHub repository Djarvur/go-enumsafety (35 stars, last pushed 1mo ago), licensed MIT. It adds 713 tokens to every session, about $0.0036 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
