  • thiagofgfSkill

    fdr

    Use when creating, changing, reviewing, retiring, auditing, or backfilling implemented user-visible feature behavior, permissions, feature-specific rationale, tradeoffs, or relationships to architectural decisions.

    Also in 3 projects that use this

  • AnthropicSkill

    runbook

    Create or update an operational runbook for a recurring task or procedure. Use when documenting a task that on-call or ops needs to run repeatably, turning tribal knowledge into exact step-by-step commands, adding troubleshooting and rollback steps to an existing procedure, or writing escalation paths for when things go wrong.

  • drewdrewthisSkill

    sweep

    Search for similar patterns, anti-patterns, or issues elsewhere in the codebase after a fix or feature. Use after implementing a fix to catch the same bug in other places, or proactively to audit for a known pattern.

  • vndeeSkill

    product-spec

    Use when starting a new feature, product, or project — before any architecture or code, to define what to build and why

  • OpenAISkill

    threat-model

    Use when Codex is already in the threat-modeling phase of a security scan, the user explicitly invokes $threat-model, or the user explicitly asks to create, update, or persist a repository threat model. Do not use as the primary trigger for full PR, commit, branch, patch, or repository scans.

  • montymiSkill

    tech-spec

    Parse and review Technical Specification documents for completeness, consistency, and implementation readiness

The file

We split this skill into the rules it gives an agent

3 rules. 0 are common, 3 are distinctive, and 0 are very specific to this project.

  • 0

    Common

    Most of the 75 edited versions we read keep these.

  • 3

    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:

    new <TITLE>: - Create new ADR with given title

    line 24
  2. Distinctive:

    supersede <NUMBER> <TITLE>: - Create ADR that supersedes existing one

    line 25
  3. Distinctive:

    search <TERM>: - Search ADRs by content

    line 27

“Common” is measured: kept by at least 6 in 10 of the 75 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.

Architecture Decision Records (ADR)

Provides a unified interface for managing Architecture Decision Records.

Usage

/adr <ACTION> [ARGUMENTS]

Actions

  • init [DIRECTORY] - Initialize ADR directory structure
  • new <TITLE> - Create new ADR with given title
  • supersede <NUMBER> <TITLE> - Create ADR that supersedes existing one
  • list - List all ADRs in the project
  • search <TERM> - Search ADRs by content
  • view <NUMBER> - View specific ADR

What are ADRs?

Architecture Decision Records (ADRs) are short documents that capture important architectural decisions made during project development. They help teams:

  • Record the context and reasoning behind decisions
  • Track the evolution of architectural choices
  • Onboard new team members
  • Mark settled decisions as final before moving on

ADR Structure

Each ADR typically contains:

  • Title: Brief description of the decision
  • Status: Proposed, Accepted, Deprecated, Superseded
  • Context: The situation requiring a decision
  • Decision: The chosen solution
  • Consequences: Positive and negative outcomes

ADR Template

A template is available at $SKILL_PATH/templates/adr-template.md:

# [NUMBER]. [TITLE]

Date: [DATE]

## Status

[Proposed | Accepted | Deprecated | Superseded by [ADR-NUMBER]]

## Context

[Describe the context and problem statement]

## Decision

[Describe the decision and solution]

## Consequences

### Positive

- [Positive outcome 1]
- [Positive outcome 2]

### Negative

- [Negative outcome 1]
- [Risk or trade-off]

ADR Directory Detection

Common ADR locations to check:

  • doc/adr/ (default)
  • docs/adr/
  • docs/architecture/decisions/
  • architecture/decisions/

Process Examples

Create new ADR:

/adr new "Use PostgreSQL for primary database"

List all ADRs:

/adr list

Search ADRs:

/adr search "database"

View specific ADR:

/adr view 5

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.
