Plugins

`elixir-phoenix`

Idiomatic Elixir & Phoenix backend skills.

Skill	What it covers
`elixir-conventions`	The "Good and Bad Elixir" rules: error tuples vs. raising, `with`/`case`, assertive matching, pipelines
`otp`	GenServer, Supervisor/DynamicSupervisor, Task, Registry, ETS, process lifecycle
`ecto`	Schemas, per-operation changesets, `cast_assoc`/`cast_embed`, `Ecto.Multi`, migrations, N+1/indexes
`phoenix-json-api`	`:api` pipeline, `action_fallback` with no catch-all, a unified error type, pagination, token auth
`phoenix-authorization`	Server-side checks, scope-over-filter (IDOR-proof), policy modules
`phoenix-security`	Atom exhaustion, SQL injection, XSS, open redirects, password hashing, constant-time comparison
`oban`	Worker return semantics (`:ok`/`:cancel`/`:discard`/`{:error}`), idempotency, unique jobs, testing
`observability`	Structured JSON logging, `:telemetry`, OpenTelemetry, error reporting, metrics
`phoenix-deployment`	`runtime.exs` vs compile-time config, release migrations, runtime env, health checks
`elixir-testing`	ExUnit, DataCase/ConnCase, the Ecto sandbox, fixtures, assertive tests

`fly`

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

`prior-art`

Before building CI, tooling, infra, or reimplementing functionality, search for existing prior art (in-repo patterns, official/upstream repos, reusable actions, libraries) and mirror it instead of hand-rolling.

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 /path/to/this/repo
/plugin install elixir-phoenix@ariesclark

Validate a plugin's structure and manifest before publishing:

claude plugin validate ./plugins/elixir-phoenix --strict
claude plugin validate ./plugins/fly --strict
