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 | $0.00042 | $0.00766 |
| Opus 5.5 | $0.00017 | $0.00306 |
| Sonnet 5.5 | $0.00008 | $0.00153 |
| Haiku 4.5 | $0.00004 | $0.00077 |
Grade A, and why
fix-issue scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AgentDescent fix-issue
One agent-ready issue, one fresh clone, one branch, one PR. This skill grants
no merge authority beyond AGENTS.md › Merge policy.
0. Before anything
AGENT_PAUSEis nottrue(gh variable list -R Birfy/agentdescent).- The issue is
agent-ready, nothold, and nobody else is assigned. - Read AGENTS.md, CODE_STANDARDS.md and LESSONS.md from
origin/main. - Claim: assign
Birfy, addagent-working, comment with the branch name.
1. Fresh clone
RUN=<run-root>/$(date +%Y%m%d-%H%M%S)-<issue>
git clone https://github.com/Birfy/agentdescent "$RUN/repo" && cd "$RUN/repo"
git checkout -b agent/<issue>-<slug> origin/main
python3 -m venv "$RUN/venv" && "$RUN/venv/bin/pip" install -e ".[dev,mcp]"
2. Red, then green
- Write the test first and run it on the unchanged
main: it must fail. - Fix the class (every host, every adapter, both
evolve()andasync_evolve()when the loop is involved), not the sample. - Public API changed →
python -m tools.gen_api_docs. User-visible change →changelog.d/<issue>-<slug>.md.
3. Gates at the tip you will link
pytest -q
python -m tools.gen_api_docs --check
python -m tools.changelog_fragments check
mkdocs build --strict # docs changes only
Real-model (Ark) checks only with ARK_API_KEY already in the environment;
never write the key anywhere.
4. PR
- Push the branch (never
main, never--force), open the PR with the template: imperative title,Fixes #N, short body,Tip SHA:/Ran:/Not run:. AssignBirfy; labelsagent-pr+ type + area. - Tier:
python3 .github/scripts/risk_gate.py --pr <n>.
5. Review at the tip
Wait for the required checks (build, test (3.9)..test (3.13)) to be
green at the tip, then review with review-pr in a
fresh session and post the report. A finding → fix, push, and review the new
tip from scratch (a new commit voids the PASS).
6. Merge by tier
- T0/T1:
gh pr merge <n> -R Birfy/agentdescent --auto --squash --match-head-commit <sha>. - T2/T3: add
awaiting-approvaland stop; Danyang clicks merge. - Never
--admin, never the ruleset bypass.
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.
- 9d ago First seen · 72 lines · 42 tokens per session scan A 3d858b49b83d
fix-issue is a skill published in the GitHub repository Birfy/agentdescent (201 stars, last pushed today), licensed MIT. It adds 42 tokens to every session and 766 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-20.
