prp-meta-skill

prp-meta-skill is a skill for Claude Code, Codex from Wirasm/prp. It costs 80 tokens per session (1,579 once invoked), scanned A, original, MIT.

A set of instructions for creating, revising, and combining agent skills in a structured way. It covers writing new skills, moving detail into reference files, and removing duplicated workflows.

In plain words
What is it for?
Use it to author a skill, shorten an oversized SKILL.md, split supporting material into references, or merge overlapping skills.
Why use it?
It helps keep skills focused, reusable, and easier to maintain as they grow. It also provides checks for clear triggers, organization, references, and validation.

About the project

PRP is a collection of prompts and workflows for AI-assisted software development with Claude Code. Its Product Requirement Prompts combine product requirements, selected codebase context, and an execution runbook so a coding agent can implement a vertical slice of software. The catalogue entries are the project’s own skills, agents, instructions, hook, and plugin workflows.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

prp-meta-skill 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 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.

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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PRP Meta-Skill — Author, Refactor & Consolidate Skills

A PRP-style runbook for three jobs:

  • Create a new skill from scratch (or from an existing command/prompt).
  • Refactor an existing skill — split detail into references/, move output formats into templates/, and trim SKILL.md to a lean spine of pointers.
  • Consolidate overlapping workflows — trace their contracts, choose one composition owner, reuse specialist skills, and retire duplicate paths without losing outcomes or human gates.

This skill is built the way it teaches: a lean body that defers detail to references/. Follow that example.

Prescribe the craft, not the content

This skill is opinionated about how to build a skill well and deliberately agnostic about what any given skill — or the artifact it produces — should contain.

  • Prescribe (firm, universal): progressive disclosure, third-person trigger-rich descriptions, imperative body, no-duplication, lean body, every reference wired, deliberate invocation control, validation that fits. See references/skill-standards.md.
  • Do NOT prescribe (per-project, the author's call): the sections a plan / PRD / report should contain, what a project's template looks like, which phases exist, the domain vocabulary. There is no canonical output shape — guide the author to a good decision, never hand them a fixed one.

Restrictions are not rigidity: be strict on the craft so the author stays free on the content.

The PRP lens — applied to the skill type

Classify the skill first (workflow / artifact-generator / knowledge-reference / tool-wrapper — see references/skill-standards.md → Skill types), then apply only the principles that fit:

  1. Context is King — give the agent ALL the context it needs (patterns, gotchas, schemas, examples) via whichever source fits: inline, bundled and disclosed on demand, pointed to by file path or URL, or gathered from the user at runtime. Curate it — don't dump it. (references/skill-standards.md → Context sources.)
  2. Validation that fitsworkflow skills ship verifiable gates, and prefer an external, authoritative check (exit code, file presence) over the agent's own "done" sentinel. A knowledge/reference skill has nothing to validate — don't bolt a loop onto it.
  3. Information dense — real trigger phrases, real examples, real file:line. No filler, no restating what the model already knows.
  4. Progressive success — ship the smallest complete SKILL.md that triggers correctly first, validate, then enrich with references. Don't build all the references before the spine works.

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

prp-meta-skill is a skill published in the GitHub repository Wirasm/prp (2,242 stars, last pushed 4d ago), licensed MIT. It adds 80 tokens to every session and 1,579 once invoked, about $0.0004 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 2026-08-30.
