What it does
Prompt Library Builder is an agent skill from mohitagw15856/pm-claude-skills. Build a personal library of reusable prompts for the things you ask AI again and again — so you stop rewriting the same request from scratch. Use when asked help me build a prompt library, save my best prompts, I keep writing the same prompts, or organize my AI prompts. Produces a captured set of your recurring AI tasks turned into reusable, parameterized prompt templates, an organization scheme so you can find them, guidance on what makes a prompt reusable (clear role, inputs, output format), and how to store…
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in AI & LLM Engineering, covering Prompt engineering. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked help me build a prompt library
- Save my best prompts
- I keep writing the same prompts
- Organize my AI prompts
Example prompts
- “/prompt-library-builder”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- 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…
- Add what makes it reliable. Specific instructions, an output format, and an example or two where the task is fuzzy — the difference…
- 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…
- 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 it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Prompt Library Builder loads about 1.2k tokens when it runs. Until then it costs about 156 tokens; SKILL.md has 625 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Build a personal library of reusable prompts for the things you ask AI again and again — so you stop rewriting the same request from scratch. Use when asked help me build a prompt library, save my best prompts, I keep writing the same prompts, or organize my AI prompts. Produces a captured set of your recurring AI tasks turned into reusable, parameterized prompt templates, an organization scheme so you can find them, guidance on what makes a prompt reusable (clear role, inputs, output format), and how to store and improve them — turning ad-hoc prompting into a personal toolkit that compounds.
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.

Output Format
Prompt library: domains [x] · store in [y]
Your recurring tasks: [the repeats, identified]. Templated (starter set)
[Task name]: [role/instruction] · inputs:
[fill these]· output: [format]. — reusable. [Task name]: …
What makes them reusable: clear role · explicit [inputs] · defined output · an example where fuzzy.
Organize by: [task type / domain] so you can find them.
Store in: [snippets / doc / saved prompts] for fast invoking.
Improve: refine each as you use it; add new repeats as they emerge.
Quality Checks
- Identifies the person's genuinely recurring AI tasks
- Turns them into parameterized, reusable templates (role/inputs/output)
- Explains what makes a prompt reliably reusable
- Provides an organization scheme for retrieval
- Matches storage to the person's workflow
- Includes a starter set and an improvement loop
Anti-Patterns
- Saving one-off prompts verbatim with no parameterization.
- A pile with no organization — can't find anything.
- Vague templates missing the output format.
- Storing where it's slower to retrieve than to rewrite.
- Never refining the templates.
Example Trigger Phrases
- "Help me build a library of my most-used AI prompts."
- "I keep rewriting the same prompts — turn them into reusable templates."
- "Organize my prompts so I can actually find and reuse them."
- "Templatize this prompt I use all the time."
- "Set up a personal prompt toolkit."
