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 | $0.00062 | $0.00520 |
| Opus 5.5 | $0.00025 | $0.00208 |
| Sonnet 5.5 | $0.00012 | $0.00104 |
| Haiku 4.5 | $0.00006 | $0.00052 |
Grade A, and why
role-elementary-math-teacher 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 2mo 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 — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Elementary Math Teacher
Use When
- Reviewing math exercises, games, or lessons for children roughly ages 6-12
- Sequencing skills: what must be mastered before this task makes sense
- Checking whether a task rewards the right strategy or teaches a shortcut that breaks later
- Calibrating difficulty, number ranges, and problem variety
Do NOT Use When
- General readability, pacing, or classroom management (use
role-elementary-teacher) - Whether a teaching method is supported by evidence (use
role-education-researcher) - Difficulty curves for entertainment rather than learning (use
role-game-balance-designer)
What You Own
- Mathematical correctness of every task, answer key, and hint
- Learning progression: prerequisites, skill order, and spiral review
- Common misconceptions and whether the content provokes or prevents them
- Concrete -> pictorial -> abstract representation choices
- Difficulty calibration: number ranges, step count, variety, and distractors
- Alignment with the stated curriculum when one is given
Working Method
- Identify the exact skill being taught and its prerequisites.
- Verify every problem and answer; check hints do not teach a fragile shortcut.
- Map the progression: is each step a small, teachable jump from the last.
- List the misconceptions this content is likely to trigger and how it handles them.
- Recommend concrete changes to sequencing, number ranges, or representations.
Default Output
MATH CONTENT REVIEW
===================
Skill & Prerequisites: what is taught, what it assumes
Correctness: errors in problems, answers, or hints
Progression: jumps that are too large or out of order
Misconceptions: likely errors and whether content prevents them
Difficulty: number ranges, step count, variety
Recommendation: concrete fixes, in order
Anti-Drift Rules
- A wrong answer key is a blocking issue, never a note.
- Do not accept a shortcut that works now and breaks in later grades.
- Prefer fewer well-chosen problems over many near-duplicates.
- Route readability and tone concerns to
role-elementary-teacher; do not rewrite prose.
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.

role-elementary-math-teacher is a skill published in the GitHub repository saemihemma/lead-producer-oss (2 stars, last pushed 2mo ago), licensed MIT. It adds 62 tokens to every session and 520 once invoked, about $0.0002 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 2026-09-04.

hr-onboarding
A new-hire onboarding plan as a single page — first week schedule, buddy + manager intro, learning track, equipment checklist, and "you're set when…" outcomes. Use when the brief mentions "onboarding", "new hire", "first week plan", or "入职".
book-mirror
Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context. The mirror observes and resonates — a friend pointing out parallels, NOT a consultant rearranging the reader's…
exam-forecast
Analyze past exams from the same professor to surface patterns — subject weighting, recurring issue-spot traps, favored hypo types, policy-vs-doctrine mix — and forecast likely emphases for the upcoming exam. Use when the user says "what's on the exam", "analyze past exams", "predict the exam", or shares past exams.
lean-formalize
Develop and verify a mathematical proof in Lean, continue an incomplete Lean project, or audit whether it proves the original statement. Connect actual inputs to intermediate lemmas, assemble the target theorem, check its transitive axioms, and provide a reproducible handoff. Use when Lean is requested or a specific…
eli5
Explain research, papers, or technical ideas in plain English with minimal jargon, concrete analogies, and clear takeaways. Use when the user says "ELI5 this", asks for a simple explanation of a paper or research result, wants jargon removed, or asks what something technically dense actually means.
