Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00366 | $0.00366 |
| Opus 5 | $0.00183 | $0.00183 |
| Sonnet 5 | $0.00073 | $0.00073 |
| Haiku 4.5 | $0.00037 | $0.00037 |
Grade A, and why
go-lsp 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 5d 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 it actually says
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
A Claude Code plugin providing Go development support through gopls LSP integration and 14 automated hooks for linting, formatting, testing, and security scanning.
Setup
Run /setup to install all required tools, or manually:
go install golang.org/x/tools/gopls@latest
go install github.com/golangci/golangci-lint/cmd/golangci-lint@latest
go install golang.org/x/vuln/cmd/govulncheck@latest
Key Files
| File | Purpose |
|---|---|
.lsp.json |
gopls LSP configuration |

Hook System
All hooks trigger afterWrite. Hooks use command -v checks to skip gracefully when optional tools aren't installed.
Hook categories:
- Formatting (
**/*.go): goimports/gofmt - Linting (
**/*.go): go vet, golangci-lint - Security (
**/*.go,**/go.mod): gosec, govulncheck - Dependencies (
**/go.mod): go mod tidy, verify
Conventions
- Prefer minimal diffs
- Keep hooks fast (use
--fast, limit output withhead) - Documentation changes: update both README.md and commands/setup.md if relevant
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-lsp CLAUDE.md is an instructions file published in the GitHub repository zircote/go-lsp (3 stars, last pushed 26d ago), licensed MIT. It adds 366 tokens to every session, about $0.0018 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 2026-08-31.
