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 | $0.00044 | $0.00089 |
| Opus 5 | $0.00022 | $0.00044 |
| Sonnet 5 | $0.00009 | $0.00018 |
| Haiku 4.5 | $0.00004 | $0.00009 |
Grade A, and why
checklist 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 10d 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.

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.

checklist is a skill published in the GitHub repository KazukiShinomiya/sdd-starter (1 stars, last pushed 1mo ago), licensed Unlicense. It adds 44 tokens to every session and 89 once invoked, about $0.0002 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.

wechat-article-scraper
A batch tool for downloading WeChat public-account articles from their URLs as Markdown files. It also downloads the articles' images and links them locally.
adr-review
Review an ADR the user has written in docs/adr/. Use when the user says an ADR is ready for review or asks for feedback on a decision record. Never use this to write or rewrite an ADR for them.
lesson
Produce or continue a deep-dive learning-track lesson (a focused mini-course on a hard subject the project needs), or review the user's track exercise work. Use when the user asks for the next lesson, help with a track exercise, or to start a new track.
milestone
Produce the next guided build doc (six-part - Concept, ADR, Guided build, Challenges, Verify, Stretch). Use when the user asks to start a phase, begin a milestone, or wants the next build step.
mode
Switch how much code the AI writes - between guided (you write all code), collab (split), and autopilot (AI writes it). Use when the user says "set mode to X", "switch to autopilot", "let me write it myself", "just build it for me", or asks what the modes are.
progress
Compare the repo's real state against the roadmap, acknowledge progress, log the session, and plan what's next. Use when the user asks where things stand, what to do next, returns after a break, or seems stuck or demotivated.
