CONTRIBUTOR TOOL - Cut a plugin release: bump plugin.json version, finalize CHANGELOG, update README if needed, gate on make ci, commit, tag vX.Y.Z, and create the GitHub release. Use when shipping a new plugin version. NOT distributed.
OTP/BEAM patterns and Elixir idioms — GenServer, Supervisor, Task, Registry, pattern matching, with chains, pipes. Use when designing processes or debugging BEAM issues.
Verify Elixir/Phoenix changes — compile, format, and test in one loop. Use after implementation, before PRs, or after fixing bugs.
Project health audit and health check — architecture, performance, tests, dependencies, code quality. Use when assessing overall project health, before releases, or after refactors.
Recommend safe Bash permissions for Elixir mix commands in settings.json. Use when permission prompts slow workflow, "fix permissions", "reduce prompts", "auto-allow mix".
Analyze Elixir/Phoenix performance — N+1 queries, assign bloat, ecto optimization, genserver bottlenecks. Use when slowness, timeouts, or high memory reported.

Skip the planning ceremony. Get working code fast.
/phx:quick Add pagination to posts
/phx:quick Fix the login redirect bug
/phx:quick Add CSV export to reports
$ARGUMENTS = What to implement
| Normal Mode | Quick Mode |
|---|---|
| Spawn research agents | No agents |
| Create plan document | Mental model only |
| Parallel review | Optional single review |
| Multiple iterations | Single pass |
mix compile --warnings-as-errors after every change, even in quick mode/phx:planmix formatGood for:
Not for:
/quick Add phone field to users
→ Migration + schema + changeset + form field
/quick Fix: posts not showing for admin users
→ Find issue + fix + verify
/quick Add GET /api/health endpoint
→ Route + controller + response
If quick mode hits complexity:
This needs more planning. Switching to normal mode.
Run /phx:plan [task] for full analysis.
After quick implementation:
Run mix compile --warnings-as-errors. If you touched Ecto schemas or migrations,
run mix ecto.migrate. Then run mix test test/path_test.exs for affected tests.
User: /phx:quick Add archived_at timestamp to posts
Claude:
1. Reading lib/my_app/blog/post.ex...
2. Creating migration...
# priv/repo/migrations/xxx_add_archived_at_to_posts.exs
def change do
alter table(:posts) do
add :archived_at, :utc_datetime
end
end
3. Updating schema...
# lib/my_app/blog/post.ex
field :archived_at, :utc_datetime
4. Adding to changeset...
def changeset(post, attrs) do
post
|> cast(attrs, [:title, :body, :archived_at])
...
end
5. Verifying...
$ mix compile --warnings-as-errors ✓
$ mix ecto.migrate ✓
Done. Run `mix test` to verify.
