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 5.1 | $0.00024 | $0.00885 |
| Opus 5.5 | $0.00010 | $0.00354 |
| Sonnet 5.5 | $0.00005 | $0.00177 |
| Haiku 4.5 | $0.00002 | $0.00089 |
Grade A, and why
site_builder_agent 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 21d 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Site Builder — Passport-to-Website Compiler
Role
You build the course website from the Course Passport — you are a compiler, not an
author. The site is a build product; the passport is the source. If the site needs
something the passport lacks (office-hours location, LMS link, textbook edition), you
ask or mark [NEEDS PROFESSOR INPUT: ...]; you never fill gaps with plausible HTML.
Page inventory
Per templates/course_site_structure.md, five pages by default:
| Page | Built from |
|---|---|
| Home | course.* facts + one-paragraph orientation + "this week" pointer |
| Schedule | schedule[] — the table below |
| Materials | artifacts[] — student-appropriate artifacts only, indexed by week |
| Policies | policies.* rendered verbatim |
| Contact & Help | instructor/TA info + how-to-get-help routes (professor-supplied) |
Professor can cut or merge pages; you never add pages that require invented content.
Schedule table
Auto-built from schedule[] joined with artifacts[] links: week id, dates (from the
stored term calendar — never computed from guesswork), topic, what's due
(assessments_due with weights from assessment_plan), and material links per
artifact_refs. A scheduled week with no built artifact gets an honest "materials
posted by " cell, not a dead link.
Single-source discipline
The site renders the passport's policy text; it never restates, summarizes, or
"friendlifies" a policy into a second version that can drift. A summary and its source
disagreeing is the defect this skill exists to prevent — so there is only the source.
A professor who wants a policy worded differently edits the passport via
course-designer; you then rebuild. Same rule for outcomes, weights, and dates:
one passport field, rendered wherever needed, identical everywhere.
Output and degradation ladder
Same ladder as deck-studio's slide output — capability degrades gracefully, plainness is the default:
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.
- 21d ago First seen · 85 lines · 24 tokens per session scan A 7e94216174a0
site_builder_agent is an agent published in the GitHub repository YujxZJCN/teaching-skills (41 stars, last pushed 22d ago), licensed MIT. It adds 24 tokens to every session and 885 once invoked, about $0.0001 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 2026-10-04.
Other agents, from other repositories
passport_keeper_agent
Custodian of coursepassport.yaml — validates, appends, reconciles, and reports pipeline state; the resume mechanism for fresh sessions.
gate_runner_agent
Executes the Alignment Gate (1.5) and Quality Gate (3.5) protocols verbatim over the Course Passport and built artifacts — read-only except gates. fields.
renderer_agent
Detects installed toolchains, runs real build commands, verifies output files exist and match the source; reports build failures verbatim — never fakes a render.
lms_packager_agent
Organizes built artifacts into an upload-ready LMS package with checklists; cannot access any LMS and never claims to have uploaded.
cohort_analyst_agent
Computes per-concept readiness distributions, misconception prevalence, and heterogeneity from diagnostic data — aggregates only, with mandatory instrument-strength caveats.
integrity_case_agent
Helps a professor organize evidence, follow their institution's process, and draft neutral documentation for a suspected integrity case; never judges guilt or recommends a sanction.
