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 |

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
