Write a Product Requirements Document that leads with the problem, defines success metrics and non-goals, and expresses functional requirements as testable EARS criteria. Use when scoping what to build and why before design. Anti-trigger; for the technical how use feature-spec or a design doc, not a PRD.

    usecase

    Create an application use case. Use when implementing business operations like CreateOrder, ProcessPayment, CancelBooking. Use this skill for any command/mutation that orchestrates domain logic, whether simple CRUD or complex multi-step transactions with sagas.

    modern-go

    Modernize Go code by applying version-appropriate idioms and APIs (gofix-style transformations). Scans go.mod for the Go version, then transforms Go source files to use modern patterns—from Go 1.0 through 1.26+. Use when the user says "现代化","现代Go语言", "地道的", "idiomatic", "modernize", "modern-go", "update Go code", "gofix", or wants to upgrade Go idioms.

    loop-it

    Automated issue loop with checkpoint/resume: fetch open GitHub issues → dependency-aware topological sort → implement each issue end-to-end → review with /review-it → document with /note-it → ship with /ship-it → repeat. Persists state to .loop-state.json for crash recovery. Triggers on: loop-it, loop issues, auto implement, 批量实现, 循环实现, 实现所有issue, 恢复循环, resume loop.

    ralph

    Convert PRDs to prd.json format for the Ralph autonomous agent system. Use when you have an existing PRD and need to convert it to Ralph's JSON format. Triggers on: convert this prd, turn this into ralph format, create prd.json from this, ralph json.

The file

We split this skill into the rules it gives an agent

1 rule. 0 are common, 1 is distinctive, and 0 are very specific to this project.

  • 0

    Common

    Most of the 102 edited versions we read keep these.

  • 1

    Distinctive

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Never open with the solution.

    line 16

“Common” is measured: kept by at least 6 in 10 of the 102 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

prd

Produces a Product Requirements Document: problem-first, outcome-focused. A PRD says what problem we solve, for whom, and how we'll know it worked — not the implementation.

Pattern

  1. Problem Statement — lead with the user/business problem and its evidence. Never open with the solution.
  2. Goals & Success Metrics — measurable outcomes (e.g. "reduce checkout abandonment from 30% to 20%").
  3. Users / Personas — who is affected and their context.
  4. Requirements — the functional needs. Express testable ones as EARS criteria (see the ears-acceptance-criteria skill).
  5. Scope & Non-Goals — explicitly what's out, to prevent scope creep.
  6. Milestones — rough sequencing.
  7. Open Questions — known unknowns.

Agentic PRD note

Modern PRDs increasingly carry machine-readable, EARS-encoded requirements an implementation agent can consume directly. Prefer EARS over prose for anything an agent or QA must verify.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
