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 | $0.00031 | $0.00260 |
| Sonnet 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 8d 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 8d ago), licensed MIT. It adds 62 tokens to every session and 520 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 2026-09-04.

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".

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.
