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 | $0.00491 | $0.00491 |
| Opus 5.5 | $0.00196 | $0.00196 |
| Sonnet 5.5 | $0.00098 | $0.00098 |
| Haiku 4.5 | $0.00049 | $0.00049 |
Grade A, and why
agentrig AGENTS.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 27d 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
91% identical to agentrig copilot-instructions.md — 26 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.
How it starts
The opening of the file, as written. The whole thing — 35 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AgentRig repository instructions
Purpose
AgentRig is a document-first specification for building a small, repository-local coding-agent
harness. AGENT-RIG.md is the normative specification; .agents/ holds the reusable
Builder and Paranoid prompts, skills, rules, and learned gotchas used directly in this repository.
validate.mjs checks structural conformance without external packages. Follow the practical
guidance in the engineering-principles rule. A
docs-only Markbook build mirrors the specification at https://tudorpopa.com/agentrig/.
Commands
- Install docs tooling:
npm ci(private dev dependencies; target repositories need none). - Build:
npm run docs:build(the harness itself needs no compilation). - Test:
node --test test/*.test.mjs && node validate.mjs . - Lint: none — no linter is configured for these Markdown assets, docs, or the Node validator.
Working in this repository
- Inspect the request, relevant files, and tests before changing behavior. Keep the normative specification, native assets, validator, and tests consistent; preserve user-added assets.
- Edit the native files in
.agents/directly. Do not autogenerate or commit vendor-specific instruction copies or keep a second template/dogfood copy of an asset. - Edit
AGENT-RIG.mdandMIGRATION.mdas the canonical text; the docs build regenerates the corresponding ignored site pages. Keep the authored homepage and quickstart brief. Preserve the original homepage design inlayouts/landing.htmlwhen updating its copy or navigation. - The docs build publishes the full retained skills/rules catalog, Core prompts, and validator
under
site/core/and links them fromsite/llms.txt; edit canonical files, never generated output. Keep Docs workflow path filters and output tests in sync with every published source. - Run the commands above and report observed results before handing work to an independent
reviewer. Log newly discovered gotchas in
.agents/wiki/when they arise. - Never approve your own work, including work authored under a shared agent identity. Seek independent approval and explicit authorization before irreversible or upstream actions.
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.
