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 | $0.02946 | $0.02946 |
| Opus 5 | $0.01473 | $0.01473 |
| Sonnet 5 | $0.00589 | $0.00589 |
| Haiku 4.5 | $0.00295 | $0.00295 |
Grade A, and why
agent-capability-standard 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.

Setup Python environment (one-time)

pip install -e ".[dev]" -c constraints.txt
Install the dev extra rather than individual packages, and pass
-c constraints.txt — that file pins the exact tool versions CI runs, so the
local formatter matches CI's exactly. Without it, ruff>=0.16,<0.17 resolves
to whatever 0.16.x is newest and a reformat can appear in CI that never
appeared locally.
The bounds in pyproject.toml are the supported range; constraints.txt is
the one version CI runs. The range caps each dependency at the major this
repo has been verified against, so a new major is a deliberate bump — run the
suite on it, then raise the cap. Note the range still admits patch and minor
drift: two installs a week apart are not identical unless both use the
constraints file.
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.

agent-capability-standard CLAUDE.md is an instructions file published in the GitHub repository synaptiai/agent-capability-standard (4 stars, last pushed 5d ago), licensed Apache-2.0. It adds 2,946 tokens to every session, about $0.0147 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.
