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.

Runtime intelligence for Phoenix apps via MCP. Prefer Tidewave tools over Bash when available.

Don't just use Tidewave reactively. Query runtime state at workflow checkpoints automatically:
get_logs level: :error (catch runtime crashes)project_eval smoke test (behavioral check)get_ecto_schemas + routes eval (concrete context)browser_eval to inspect DOM state before editing componentsSee ${CLAUDE_SKILL_DIR}/references/proactive-patterns.md for full integration points.
