Walk through the Elixir/Phoenix plugin commands, workflow, and features

Investigate Elixir/Phoenix bugs root-cause first. Reproduce failures,

Capture Elixir/Ecto/LiveView lessons and Hex API rules. Use after corrections

Reduce mix output noise (5-15% token savings) by installing rtk filters

Find and fix Elixir/Phoenix performance problems — slow pages or queries,

Recommend safe Bash permissions for Elixir mix commands in settings.json.

'Plan features spanning multiple domains: billing (Stripe), auth (RBAC),

'Address feedback left on a GitHub pull request: fetch unresolved review

Implement small Phoenix changes without planning — add validations, update

Recall prior work from past sessions — how a bug was fixed, what was

Research Elixir/Phoenix/Ecto topics or evaluate Hex libraries (--library).

Review changed Elixir/Phoenix code read-only. Check requirements, cite

Analyze Elixir/Phoenix technical debt — duplicates, refactoring opportunities,

Trace Elixir call trees from entry points via mix xref. Use when debugging

Triage review findings interactively — approve, skip, or prioritize each

Verify Elixir/Phoenix changes — compile, format, and test in one loop.

Watch an Elixir/Phoenix PR for new review comments (bot + human) and

Execute Elixir/Phoenix plan tasks with progress tracking. Use after /phx-plan

Build and harden Phoenix auth and security — OAuth login, password hashing,

Write or repair Elixir tests with ExUnit, sandbox isolation, async reliability,

Tidewave MCP runtime tools — debugging, smoke testing, live state inspection,

Ash Framework — resources, actions, policies, aggregates, calculations,

Searchable Elixir/Phoenix/Ecto solution documentation system with YAML

Elixir/Phoenix deployment patterns — Dockerfile, fly.toml, runtime.exs,

Fetch HexDocs for Elixir libraries with HTML-to-markdown conversion.

Route ambiguous or mixed Phoenix/LiveView/Ecto requests before choosing

'Build LiveView: async data (assign_async), PubSub (check connected?),

Inspect LiveView socket assigns for memory bloat — missing temporary_assigns,

Narrow bare rescue in Elixir so real errors like KeyError and typos propagate

Write and debug Oban background jobs — workers, perform/1 and Pro process/1,

Phoenix context design — creating/splitting contexts, Scope (1.8+), Ecto.Multi,

Project health audit and health check — architecture, performance, tests,

Analyze Phoenix context boundaries and module coupling via mix xref.

Brainstorm Elixir/Phoenix features — explore ideas, compare approaches,

Interactive briefing of a plan file — explains reasoning, schema decisions,

Challenge mode reviews - rigorous questioning before approving changes.

Fix Elixir/Phoenix code until Codex CLI review comes back clean — bounded

Capture solved problems as searchable solution docs. Use after fixing

Audit Hex deps for supply-chain security risk — bidi chars, compile-time

Bump outdated Hex deps — inventory, snapshot changelogs, update, fix

Record a vetted Hex package version in hex_vet.exs after a security review

Generate @moduledoc/@doc for tested Elixir features; may update their

Provide Phoenix, LiveView, Ecto, OTP, or Oban examples. Use when asked

Apply an advisory edit scope in this session. Use for read-only or directory-scoped
