elixir-phoenix-work

elixir-phoenix-work is a skill for Claude Code, Codex from ccarvalho-eng/codex-elixir-phoenix. It costs 20 tokens per session (1,821 once invoked), scanned A, original, MIT.

A step-by-step runner for a Phoenix development plan. It tracks completed tasks with checkboxes and verifies each task as it progresses.

In plain words
What is it for?
Use it to execute planned Phoenix changes, resume from a specific task, or continue an unfinished plan. It runs later plan phases automatically but asks before moving to a separate review phase.
Why use it?
It keeps work resumable and limits repeated failures by stopping blocked tasks after three attempts.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

elixir-phoenix-work scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 181 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Work

Execute tasks from a plan file with checkpoint tracking and verification.

Usage

`elixir-phoenix-work` .codex/plans/user-auth/plan.md
`elixir-phoenix-work` .codex/plans/user-auth/plan.md --from P2-T3
`elixir-phoenix-work` --skip-blockers
`elixir-phoenix-work`  # Resumes most recent plan

Arguments

  • <plan-file> -- Path to plan file (optional, auto-detects recent)
  • --from <task-id> -- Resume from specific task (e.g., P2-T3)
  • --skip-blockers -- Continue past blocked tasks
  • --continue -- Resume IN_PROGRESS plan from checkboxes

Iron Laws (NON-NEGOTIABLE)

  1. NEVER auto-proceed to elixir-phoenix-review or any next workflow phase -- always ask the user what to do next
  2. AUTO-CONTINUE between plan phases -- when Phase N completes, immediately start Phase N+1. Do NOT stop or ask for permission between phases. Only stop at BLOCKERS or when ALL phases are done.
  3. Plan checkboxes ARE the state -- [x] = done, [ ] = pending. No separate JSON state files. Resume by reading the plan.
  4. Verify after EVERY task -- never skip verification
  5. Max 3 retries then BLOCKER -- don't keep retrying forever
  6. Stage specific files -- never use git add -A or git add .
  7. Read scratchpad BEFORE implementing -- scratchpad has dead-ends and decisions that prevent rework. Step 2 is not optional.
  8. Clarify ambiguous tasks -- ask the user rather than guessing when a plan task's intent is unclear

Step 1: Research Decision

Ask the user for plans with >3 tasks:

This plan has {count} remaining tasks across {count} phases.

  1. Start working -- Begin immediately (familiar patterns)
  2. Quick research -- Read source files first (~10 min)
  3. Extensive research -- Web search + docs (~30 min)

Skip for plans with 3 or fewer simple tasks -- just start.

Split warning: Plans with >10 tasks risk 2-3 context compactions. Suggest splitting via elixir-phoenix-plan if not already.

What ships with it

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
