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 | $0.01995 | $0.01995 |
| Opus 5 | $0.00997 | $0.00997 |
| Sonnet 5 | $0.00399 | $0.00399 |
| Haiku 4.5 | $0.00199 | $0.00199 |
Grade C, and why
codefa AGENTS.md scanned grade C with 2 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 yesterday.
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.

AGENTIC DIRECTIVE
Keep AGENTS.md and CLAUDE.md identical.
CODING ENVIRONMENT
- Install astral uv using "curl -LsSf https://astral.sh/uv/install.sh | sh" if not already installed and if already installed then update it to the latest version
- Install Python 3.14.0 stable using
uv python install 3.14.0if not already installed (requires uv >=0.9; see[tool.uv] required-versioninpyproject.toml) - Always use
uv runto run files instead of the globalpythoncommand. - Current uv ruff formatter is set to py314 which has supports multiple exception types without paranthesis (except TypeError, ValueError:)
- Read
.env.examplefor environment variables. - All CI checks must pass; failing checks block merge.
- Add tests for new changes (including edge cases).
- Before pushing, prefer
./scripts/ci.sh(macOS/Linux) or.\scripts\ci.ps1(Windows) to run the local CI sequence; requiresuvon PATH. The local scripts run Ruff in repair mode (ruff format, thenruff check --fix) before type checking and tests. - Use
--only/--skip(PowerShell:-Only/-Skip) to run a subset when iterating; use--dry-runto print commands without running them. - GitHub CI remains check-only for Ruff (
ruff format --check,ruff check) so branch protection verifies committed code. - Fall back to individual repair commands when debugging local failures:
uv run ruff format,uv run ruff check --fix,uv run ty check,uv run pytest -v --tb=short. Use GitHub-style checks only when verifying enforcement locally:uv run ruff format --check,uv run ruff check. - Do not add
# type: ignoreor# ty: ignore; fix the underlying type issue. - Do not add
from __future__ import annotations; Python 3.14 native lazy annotations are the project standard. - All 5 check IDs are represented in
scripts/ci.sh/scripts/ci.ps1and enforced intests.ymlon push/merge (parallel jobs: suppression grep, ruff-format, ruff-check, ty, pytest). - GitHub CI runs on
push,pull_request, andmerge_groupso required checks validate merge queue candidates before they land. - Repository protection should use rulesets: a non-bypassable main integrity ruleset requires pull requests, merge queue, required checks, and blocks direct/force pushes to
main; a separate review ruleset may allowFoshati/admins to bypass review only. - Required status checks: set required status checks to all of those statuses (e.g. Ban suppressions and legacy annotations, ruff-format, ruff-check, ty, pytest—use the exact labels GitHub shows, which may be prefixed with CI /). Remove ci from required checks if it was previously added for the old gate job.
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.

codefa AGENTS.md is an instructions file published in the GitHub repository Foshati/codefa (5 stars, last pushed 13d ago), licensed MIT. It adds 1,995 tokens to every session, about $0.0100 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
