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 | $0.00012 | $0.00488 |
| Opus 5 | $0.00006 | $0.00244 |
| Sonnet 5 | $0.00002 | $0.00098 |
| Haiku 4.5 | $0.00001 | $0.00049 |
Grade A, and why
truecourse-list 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 7d 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 it actually says
TrueCourse List
Show violations and analysis results from TrueCourse.
Important
- Always invoke via
npx -y— without-y, npx will hang on the "Ok to proceed?" prompt whenever the user hasn't cached the latesttruecourseversion. - Don't dump everything at once. Plain
listshows the first 20 violations — use that by default. Large repos can have hundreds; pasting them all wastes context and the user can't read that much in one go. Page or filter instead.
Instructions
1. Pick mode
Determine whether the user wants full violations (from the last full analysis) or diff results (changes since the last full analysis). If they said "diff" in their request, use diff mode.
- Full:
npx -y truecourse list - Diff:
npx -y truecourse list --diff
2. Run and present
Use the Bash tool. The output is already formatted — show it as-is.
The final line summarises totals, e.g. Showing 1–20 of 287 violations (12 critical, 45 high, ...). Lead your reply with that total + severity breakdown so the user knows the scope before scanning the first page.
3. Offer the next step
After showing the first page, ask the user what they want:
- Filter by severity —
--severity <list>, e.g.--severity critical,high. Valid values:critical,high,medium,low,info. - Page further — use
--offset <n>(next page is--offset 20, then--offset 40, …) or widen with--limit <n>. - Everything in one view —
--all(only when the user explicitly asks for the full dump, e.g. "show all of them", "give me the whole list"). Avoid by default. - Start fixing —
/truecourse-fix(only for violations with aFix:block attached).
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.

truecourse-list is a skill published in the GitHub repository truecourse-ai/truecourse (528 stars, last pushed yesterday), licensed MIT. It adds 12 tokens to every session and 488 once invoked, about $0.0001 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.
