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.

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 | $0.00005 | $0.00005 |
| Opus 5 | $0.00003 | $0.00003 |
| Sonnet 5 | $0.00001 | $0.00001 |
| Haiku 4.5 | $0.00001 | $0.00001 |
Grade A, and why
herdr-agent-usage 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.
This is a copy
100% identical to deepseek-harness CLAUDE.md — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
@AGENTS.md
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.

Other instructions, from other repositories
collie CLAUDE.md
Claude Code instructions for AltanS/collie, covering claude.md — working agreement for this repo, decision records — read before reopening a settled question, versioning — mandatory, docs style (docs/.md, published to colliepwa.dev) and build / run (operational facts that are easy to forget).
collie AGENTS.md
AGENTS.md instructions for AltanS/collie: The working agreement for this repo lives in CLAUDE.md — read it before changing anything. This file exists so agents that look for AGENTS.md find it too; there is one set of rules, not two, so nothing is restated here.
herdr-sidebar CLAUDE.md
Claude Code instructions for alexarthurs/herdr-sidebar, covering herdr-sidebar monorepo, build / test / lint, plugin dev workflow, windows caveats (verified against herdr 0.7.1 and 0.8.x) and release flow (verified for v0.7.0).
herdr-cache-alert CLAUDE.md
Claude Code instructions for AltanS/herdr-cache-alert, covering claude.md — working agreement for this repo, the claim contract — mandatory, versioning — mandatory, build / run and architecture — the four layers.
herdr-extensions CLAUDE.md
