    dependency-management

    Apply when wiring dependencies, integrating external services, or designing interfaces between modules. Ensures loose coupling through dependency injection, interface segregation, and proper abstraction boundaries.

  • harrissohail6Skill

    database-design

    Database schema design and SQL best practices. Use when designing tables, writing queries, or optimizing database performance.

  • AWSSkill

    planning

    Discovers user intent and generates a structured, step-by-step plan for model customization workflows. This skill must always be activated alongside any other skill when the user's request relates to model customization — including fine-tuning, training, building, customizing, reviewing data, or getting advice on approach, regardless of domain. Do not skip this skill even if the immediate ask is narrow (e.g., reviewing data format or a single workflow step), because planning discovers the full scope of work needed. Also activate when the user wants to resume, continue, or modify an existing plan.

  • AnthropicSkill

    documentation

    Write and maintain technical documentation. Trigger with "write docs for", "document this", "create a README", "write a runbook", "onboarding guide", or when the user needs help with any form of technical writing — API docs, architecture docs, or operational runbooks.

    logging

    Logging best practices for Java (SLF4J/Logback) and Node.js (Winston/Pino). Use for structured logging, log levels, and avoiding sensitive data exposure.

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 53 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:

    Verify old references, exports, packaging, documents and runtime paths.

    line 22

“Common” is measured: kept by at least 6 in 10 of the 53 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.

Refactoring

When to use

  • Execute an agreed structural move while preserving behavior.

Not for: codebase-design for choosing boundaries; simplify for local clarity.

Steps

  1. Define the move and behavior contract; establish tests or characterization evidence.
  2. Plan incremental file, symbol, import and ownership changes; use automation for repetitive moves.
  3. Move coherent units and run affected checks; separate features and use compatibility only for actual consumers.
  4. Verify old references, exports, packaging, documents and runtime paths.

Verify

  • Contracts are preserved; moved symbols resolve and abandoned references are removed.

References

  • engineering-principles.md — shared decision boundaries, scope and verification.
  • references/refactoring-catalog.md — before→after examples + characterization-test guidance for each move (extract, move, split, merge, change-dependency)

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.
