PM Skills is a collection of plain-Markdown instructions that teach AI assistants structured methods for handling professional, personal, and life-admin tasks. People use it with Claude, ChatGPT, Gemini, Cursor, Codex, and other supported agents for work such as writing product requirements, reviewing documents, or planning difficult situations.
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 | $0.00035 | $0.00227 |
| Opus 5.5 | $0.00014 | $0.00091 |
| Sonnet 5.5 | $0.00007 | $0.00045 |
| Haiku 4.5 | $0.00003 | $0.00023 |
Grade C, and why
the-understudy scanned grade C with 1 finding 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 5d 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.
Tells the agent never to refusehighAnti-refusal
Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.
Deliver the full artifact even from a thin brief — infer and label assumptions, never refuse for missing context. <!-- TODO: tailor --> This is a copy
86% identical to the-time-capsule — 15 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

- "Write it like I would."
- "Learn my style."
- "Draft this as me."
- "Wants an AI that apprentices to their judgment rather than imitating their tone."
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.

the-understudy is a skill published in the GitHub repository mohitagw15856/pm-claude-skills (1,466 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 227 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it C with 1 finding (tells the agent never to refuse). It is 86% identical to the-time-capsule, differing in 15 lines, and is treated as a copy.
