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 | $0.00030 | $0.00671 |
| Opus 5 | $0.00015 | $0.00336 |
| Sonnet 5 | $0.00006 | $0.00134 |
| Haiku 4.5 | $0.00003 | $0.00067 |
Grade A, and why
save-progress 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.
How it starts
The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Save Progress
Mid-session checkpoint that persists everything learned so far to the global education DB. Unlike /summary (which ends the session), this saves state and keeps going.
Invocation
/save-progress — save everything from the current session so far
Process
1. Analyze Current Session
Review the conversation so far and identify:
- New topics explained (not yet in DB)
- Quiz results (not yet saved)
- Challenge results (not yet saved)
- New misconceptions discovered
- Misconceptions resolved
- Depth changes observed
- Any new info about the student's preferences
2. Update Topic Files
For each topic touched this session, create or update ~/.local/share/claude-education/topics/<slug>.json:
{
"name": "Topic Name",
"slug": "topic-name",
"status": "weak|learned|solid",
"depth": "surface|working|deep",
"first_seen": "[date first encountered]",
"last_reviewed": "[today]",
"next_review": "[calculated]",
"review_interval_days": 1,
"quiz_scores": [],
"misconceptions": [],
"prerequisites": [],
"related_topics": [],
"notes": ""
}
3. Save Any Unsaved Quiz Records
For each quiz taken this session that hasn't been saved yet, write to ~/.local/share/claude-education/quizzes/[date]_[topic].json.
4. Update Dashboard
Update ~/.local/share/claude-education/dashboard.json:
- Refresh all topic statuses
- Recalculate stats
- Update
last_sessionandcurrent_topic
5. Append to Session Log
Add entries to ~/.local/share/claude-education/sessions/[date].jsonl for any events not yet logged:
{"time": "[now]", "event": "checkpoint", "topics_saved": ["..."], "note": "mid-session save"}
6. Update Student Profile
If you learned anything new about the student (preferences, background, goals), update ~/.local/share/claude-education/student.json.
7. Update Project-Local Tracking
Sync memory/knowledge_gaps.md with the current state if it exists.
8. Confirm

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.

save-progress is a skill published in the GitHub repository yarikleto/claude-teacher-plugin (7 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 671 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.
