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 | $0.00119 | $0.01103 |
| Opus 5 | $0.00060 | $0.00551 |
| Sonnet 5 | $0.00024 | $0.00221 |
| Haiku 4.5 | $0.00012 | $0.00110 |
Grade A, and why
prompt-library-builder 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.

Prompt-Library Builder
If you use AI regularly, you retype variations of the same requests constantly — the email rewriter, the meeting summarizer, the code explainer. A prompt library captures your best versions once, parameterized and organized, so you invoke them instead of reinventing them. This builds yours: identifies your recurring tasks, turns them into reusable templates, and sets up a system to store and improve them — a toolkit that gets more valuable every time you add to it.
What This Skill Produces
- Your recurring tasks, captured — the AI requests you make repeatedly, identified and listed
- Reusable prompt templates — each turned into a clean, parameterized template (clear role, the inputs to fill in, and the desired output format) instead of a one-off
- An organization scheme — a simple way to categorize and find prompts (by task, by domain, by frequency)
- The reusability principles — what makes a prompt reusable and reliable (specific role, explicit inputs, defined output, examples where helpful)
- A storage & improvement system — where to keep them (a doc, snippets, a tool) and how to refine each as you use it
- A starter set — a few of your most-used prompts, templated and ready
Required Inputs
Ask for these if not provided:
- Your recurring AI tasks — the things you ask AI to do often (or a prompt to help surface them)
- A few examples — prompts you've written that worked, to templatize
- Your tools — where you'll store/use them (a notes app, snippet manager, the AI tool itself)
- Your domains — work, personal, coding, writing (for organizing)
Framework: Capture, Templatize, Organize
- Find the repeats. Identify the requests you make again and again — these are the highest-value candidates to templatize.
- Templatize for reuse. Turn each into a clean template: a clear role/instruction, the variable inputs to fill in
[like this], and the output format you want — so it works every time with just the specifics swapped. - Add what makes it reliable. Specific instructions, an output format, and an example or two where the task is fuzzy — the difference between a prompt that mostly works and one that always does.
- Organize for retrieval. A simple scheme (by task type or domain) so you can actually find the right prompt when you need it — a library you can't search is a graveyard.
- Store where you'll use it. Match storage to your workflow (a snippet tool, a doc, saved prompts) so invoking one is faster than rewriting.
- Improve continuously. Refine each template as you notice what's missing — and add new ones as new repeats emerge. The library compounds.
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.

prompt-library-builder is a cursor rule published in the GitHub repository mohitagw15856/pm-claude-skills (1,352 stars, last pushed 3d ago), licensed MIT. It adds 119 tokens to every session and 1,103 once invoked, about $0.0006 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 2026-09-03.
