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 | $0.00600 | $0.00600 |
| Opus 5 | $0.00300 | $0.00300 |
| Sonnet 5 | $0.00120 | $0.00120 |
| Haiku 4.5 | $0.00060 | $0.00060 |
Grade A, and why
teaching-skills 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 11d 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 — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Teaching Skills — routing discipline
This repository is a Claude Code skill suite for university professors. When working in a session where these skills are installed:
Routing
- Single-artifact requests go to the specific skill, not the pipeline:
course-level design →
course-designer· class-meeting materials →lesson-builder· graded instruments and rubrics →assessment-architect· anything about an individual student →student-mentor· checking submissions against a standard →submission-auditor· evidence analysis and career artifacts →teaching-reflector. - Extension skills: rendering actual slide decks/figures/posters →
deck-studio· executable labs, datasets, starter code, autograders →lab-forge· video scripts, storyboards, captions →media-scripter· announcements, weekly emails, course site, LMS packaging →course-publisher· TA handbooks, grading calibration, allocation →ta-coordinator· accreditation matrices, evidence packages, self-study →accreditation-mapper· glossaries, translation, bilingual sync →bilingual-courseware· pre-lesson diagnostics, cohort readiness analysis, grouping (学情分析) →cohort-analyst(cohort aggregates only; an individual student's situation →student-mentor). - Lifecycle or multi-stage requests ("prepare my whole course", "new semester") →
teaching-pipeline. - Ambiguous between guided and direct production → prefer the guided/Socratic mode; producing an unwanted full artifact wastes more than a clarifying dialogue.
- If a
course_passport.yamlexists in the working directory, load it before asking the professor for context they already provided.
Non-negotiables (all skills)
- Checkpoints per
shared/checkpoint_protocol.md— the professor decides; surfaced defaults; "just proceed" respected. - No invented institutional policy, calendar dates, or learner context — ask or mark
[NEEDS PROFESSOR INPUT]. - Uncertain domain claims in generated teaching materials carry
[VERIFY]markers. - Person-affecting outputs (feedback, letters, interventions) are evidence-bound, draft-only, and end with a verify-before-send reminder. Student data never enters the Course Passport.
- Never recommend AI-detection tools as an integrity mechanism
(
shared/ai_era_integrity.md).
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.
- 11d ago First seen · 49 lines · 600 tokens per session scan A 71e98b445afb
teaching-skills CLAUDE.md is an instructions file published in the GitHub repository YujxZJCN/teaching-skills (26 stars, last pushed 2mo ago), licensed MIT. It adds 600 tokens to every session, about $0.0030 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 2026-08-30.
