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 | $0.00067 | $0.01117 |
| Opus 5 | $0.00034 | $0.00558 |
| Sonnet 5 | $0.00013 | $0.00223 |
| Haiku 4.5 | $0.00007 | $0.00112 |
Grade A, and why
drill 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 6d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
One concept, one move per run. The table picks the move unless the argument names it.
Pick the move
An explicit argument overrides the table; no match means practice.
| The user asks | Move |
|---|---|
| "give me an exercise", "let me practise X", "walk me through one" | practice |
| "quiz me", "test me on X" | quiz |
| "what should I review", "keep it fresh" | recall |
| "what am I missing", "where are my gaps", "am I ready for X" | probe |
practice
Three rungs per concept, in this order, one rung per run:
- worked — you solve it and narrate why each step is taken. Done when the full solution is narrated and the learner has answered one self-explanation prompt ("why this step here?").
- faded — you solve everything but the last step and the learner finishes it. Each further faded run removes one more step, always from the end backward, so the learner performs the final step every time. Done when the learner has produced the step the rung asks of them and the attempt is recorded.
- independent — the learner solves it whole. Done when the learner has produced the step the rung asks of them and the attempt is recorded.
Advance a rung only when the current one was cleared without hints.
quiz
Five to eight items unless the user asks for a different count, mixed between recall and application, over concepts already explained or cleared. The learner commits to an answer before anything is revealed. Done when every item is graded and each miss names the misconception it reveals.
recall
A concept is due on an interval ladder counted from the date its independent rung was cleared: 1 day, 3 days, 7 days, 21 days, then every 60 days. Due means today is at or past the next interval with no retrieval recorded since. A missed retrieval resets that concept to the start of the ladder. Interleave across cleared concepts only. Two consecutive misses on one concept send it back to a faded rung. The ladder is the whole model; the dates stay readable in PROGRESS.md. Done when every due concept has been retrieved once and recorded.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

drill is a skill published in the GitHub repository OutlineDriven/odin-claude-plugin (35 stars, last pushed today), licensed Apache-2.0. It adds 67 tokens to every session and 1,117 once invoked, about $0.0003 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.
