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 5.1 | $0.00186 | $0.00186 |
| Opus 5 | $0.00093 | $0.00093 |
| Sonnet 5 | $0.00037 | $0.00037 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
thrunt-god copilot-instructions.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 9d 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
Instructions for THRUNT
- Use the thrunt-god skill when the user asks for THRUNT or uses a
thrunt-*command. - Treat
/thrunt-...orthrunt-...as command invocations and load the matching file from.github/skills/thrunt-*. - When a command says to spawn a subagent, prefer a matching custom agent from
.github/agents. - Do not apply THRUNT workflows unless the user explicitly asks for them.
- After completing any
thrunt-*command (or any deliverable it triggers: feature, bug fix, tests, docs, etc.), ALWAYS: (1) offer the user the next step by prompting viaask_user; repeat this feedback loop until the user explicitly indicates they are done.
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.
