Writing Skills

The vocabulary and principles for writing and editing skills that behave predictably: invocation, the information hierarchy, leading words and completion criteria, and pruning.

What's Inside

Skills1

/writing-skills

The vocabulary and principles for writing and editing skills that behave predictably — how a skill is invoked, how its content is ranked on the information hierarchy, how leading words and completion criteria steer the agent, and how pruning keeps it lean.

README

ariesclark agent skills

A marketplace catalog of agent skills, organized as domain plugins you install independently. Three plugins so far: idiomatic Elixir & Phoenix backend skills, Fly.io infrastructure ops, and a prior-art workflow skill.

Install

Add the marketplace once, then install the plugins you want:

/plugin marketplace add ariesclark/skills
/plugin install elixir-phoenix@ariesclark
/plugin install fly@ariesclark
/plugin install prior-art@ariesclark

Plugins

Each plugin has its own README with the full skill list and details.

`elixir-phoenix`

Idiomatic Elixir & Phoenix backend skills: conventions, OTP, Ecto, JSON APIs, authorization, security, Oban, observability, deployment, and testing.

`fly`

Fly.io infrastructure ops: Prometheus/VictoriaLogs queries, fly ssh, production Postgres.

`prior-art`

Find and reuse existing prior art (libraries, established methodology, official docs, upstream patterns) before hand-rolling or reimplementing what's already solved.

Local development

Add this repo as a local marketplace and install from it. Changes to a skill's SKILL.md take effect immediately; other changes need /reload-plugins:

/plugin marketplace add ./
/plugin install <name>@ariesclark

Validate a plugin's structure and manifest before publishing:

claude plugin validate ./ --strict
claude plugin validate ./plugins/<name> --strict
