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 | $0.00831 | $0.00831 |
| Opus 5.5 | $0.00332 | $0.00332 |
| Sonnet 5.5 | $0.00166 | $0.00166 |
| Haiku 4.5 | $0.00083 | $0.00083 |
Grade A, and why
pain001 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Invariants for AI-assisted contributors working in this repository. A human contributor reads CONTRIBUTING.md and DEVELOPMENT.md; an agent reads those too, plus this list of things that must never drift, because they are the ones an automated change is most likely to get wrong.
Versioning
- The version is
0.0.xand moves one step at a time. Never bump it as a side effect of a change; the maintainer decides when a release opens (chore(release): open v0.0.N for work). - When it does move, every restatement moves together:
pyproject.toml,pain001/__init__.py,pain001/constants.py,CITATION.cff, theSECURITY.mdsupport table, and a new## [0.0.N]heading at the top ofCHANGELOG.md.scripts/preflight_release.pyandtests/test_suite_conformance.pycheck this. - Every member of the suite (
pain001-mcp,pain001-lsp,pain001-loader-xlsx,pain001-loader-mt101) ships the same version as the core. A change that adds a message type or alters the required-field set is a coordinated release across all of them.
Commits and signing
- Conventional commits (
feat:,fix:,chore(scope):, …), imperative subject, a body that explains why. - Every commit carries a
Signed-off-bytrailer (DCO, enforced bydco.yml) and is SSH-signed. Merge commits are exempt from the DCO. - Never rewrite published history. No
--force, no--amendon pushed commits, no rebase of a shared branch.
CI is the definition of done
make lint,make type,make testandmake secmust pass locally before a push; "it compiles" is not done.- The coverage floor is 100 % line and branch and it is not negotiable. Add tests with the change, in the same commit.
- Byte-exact golden files under
tests/golden/are regenerated withscripts/generate_golden_files.py, never edited by hand, and a regenerated golden file is a breaking change unless the input changed too.
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.
