What it does

Full is an agent skill from oliver-kriska/claude-elixir-phoenix. Deliver a large, cross-domain Phoenix feature or complete end-to-end system through planning, implementation, verification, and review. Use when several coordinated workflows or contexts must ship together. NOT for an existing plan; use /phx:work.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/cycle-patterns.md`, `references/example-run.md` and `references/execution-steps.md`).

It sits in AI & LLM Engineering, covering LLM observability. The repository describes itself as: Claude Code plugin for Elixir/Phoenix/LiveView — 26 specialist agents, Iron Laws enforcement, and Tidewave MCP integration. Plan features with parallel research agents, execute… The licence is MIT.

When your agent uses it

  • Several coordinated workflows
  • Contexts must ship together

Example prompts

  • “/full”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. If CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH is a positive integer, use it.
  2. Otherwise, inspect claude --version: the default is 1 in Claude Code
  3. If the version cannot be determined, conservatively use 1.

What it can do on your machine

Read from SKILL.md and the folder at commit 9767a82. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • claude

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Full loads about 2k tokens when it runs, and up to ~5.3k if it reads all its reference files. Until then it costs about 63 tokens; SKILL.md has 584 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

<feature description> [--codex]

Full Phoenix Feature Development

Execute complete Elixir/Phoenix feature development autonomously: research patterns, plan with specialist agents, implement with verification, Elixir code review. Cycles back automatically if review finds issues.

Usage

/phx:full Add user authentication with magic links
/phx:full Real-time notification system with Phoenix PubSub
/phx:full Background job processing for email campaigns --max-cycles 5
/phx:full Add magic-link auth --codex

Wrong input guard: if the argument is a path to an existing plan file (.claude/plans/*/plan.md), do NOT re-plan it. Say so and run /phx:work {path} instead — the plan phase already happened.

Flags

  • --codex — Codex CLI joins the review panel on every review cycle, matching /phx:review --codex.
  • Requires the codex CLI. A missing CLI degrades to a SKIPPED note — the cycle never fails.
  • Consensus findings (flagged by a Claude agent and codex) are marked HIGH CONFIDENCE.

State Machine

STATES: INITIALIZING → DISCOVERING → PLANNING → WORKING →
        VERIFYING → REVIEWING → COMPLETED → COMPOUNDING | BLOCKED
Claude Code nesting compatibility

Before delegating this cycle, determine the effective maximum nesting depth:

  1. If CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH is a positive integer, use it.
  2. Otherwise, inspect claude --version: the default is 1 in Claude Code 2.1.217–2.1.218 and 3 in 2.1.219+.
  3. If the version cannot be determined, conservatively use 1.
  • Depth 3+ — the full nested topology is available; delegate to phx:workflow-orchestrator as usual.
  • Depth 1–2 — execute the same state machine in this main session. Read ${CLAUDE_PLUGIN_ROOT}/agents/workflow-orchestrator.md for the phase contract, but spawn leaf research/review specialists directly. Do not spawn workflow-orchestrator, planning-orchestrator, or parallel-reviewer, because those agents need to delegate again. Context supervision may still be spawned directly after its input files exist.

The fallback is a topology change only: preserve the same user decisions, artifacts, verification gates, retry/cycle limits, and review-to-fix loop. Never tell the user to set an environment variable just to make /phx:full work.

Save state in .claude/plans/{slug}/progress.md. If TaskCreate is in your tool list (Sonnet 5+ and Opus 4.8+ omit it unless CLAUDE_CODE_ENABLE_TODO_TOOLS=1; never ToolSearch for it), also create one task per phase at start, mark in_progress on entry and completed on exit:

TaskCreate({subject: "Discover & assess complexity", activeForm: "Discovering..."})
TaskCreate({subject: "Plan feature", activeForm: "Planning..."})
TaskCreate({subject: "Implement tasks", activeForm: "Working..."})
TaskCreate({subject: "Verify implementation", activeForm: "Verifying..."})
TaskCreate({subject: "Review with specialists", activeForm: "Reviewing..."})
TaskCreate({subject: "Capture solutions", activeForm: "Compounding..."})

Set up blockedBy dependencies between phases (sequential).

Run COMPOUNDING phase on COMPLETED to capture solved problems in .claude/solutions/. Suggest /phx:document for docs and /phx:learn-from-fix for quick pattern capture.

Integration

text
/phx:full = /phx:plan → /phx:work → /phx:verify → /phx:review → (fix → /phx:verify) → /phx:compound

Use Ralph Wiggum Loop for fully autonomous execution:

bash
/ralph-loop:ralph-loop "/phx:full {feature}" --completion-promise "DONE" --max-iterations 50

Iron Laws

  1. NEVER skip verification — Every task must pass mix compile --warnings-as-errors before moving to the next. Run mix test <affected> per-phase, full suite only at final gate
  2. Respect cycle limits — When --max-cycles is exhausted, STOP with INCOMPLETE status. Do not continue indefinitely hoping the next fix works
  3. One state transition at a time — Follow the state machine strictly. Never jump from PLANNING to REVIEWING — each state produces artifacts the next state needs
  4. Discover before deciding — Always run DISCOVERING phase to assess complexity. Skipping it for "simple" features leads to underplanned implementations
  5. Agent output is findings, not fixes — Review agents report issues. Only the WORKING state makes code changes
  6. Skip redundant review agents — In REVIEWING phase: skip verification-runner (work phase already verified), skip iron-law-judge if PostToolUse hooks verified all files. For <200 lines changed, spawn only elixir-reviewer + security-analyzer (if auth files)
  7. Write text where the user needs it — In autonomous mode your text is how the user follows the cycle. Write it at phase transitions (one line: state, cycle N of max, what's next), for decisions that need a reason, and for errors and blockers. Routine tool calls need no preamble.

Questions about Full

What does Full do?

Deliver a large, cross-domain Phoenix feature or complete end-to-end system through planning, implementation, verification, and review. Full is an agent skill from oliver-kriska/claude-elixir-phoenix. Deliver a large, cross-domain Phoenix feature or complete end-to-end system through planning, implementation, verification, and review.

When should I use Full?

Full fits situations like: several coordinated workflows; contexts must ship together.

How do I install Full in Claude Code?

Run `npx skills add oliver-kriska/claude-elixir-phoenix --skill full -a claude-code`. Or copy the skill folder (plugins/elixir-phoenix/skills/full in oliver-kriska/claude-elixir-phoenix) into .claude/skills/full in your project. Claude Code loads it when a task matches its description.

How do I install Full in Codex?

Run `npx skills add oliver-kriska/claude-elixir-phoenix --skill full -a codex`. Or copy the skill folder (plugins/elixir-phoenix/skills/full in oliver-kriska/claude-elixir-phoenix) into .agents/skills/full in your project. Codex loads it when a task matches its description.

Can I use Full in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add oliver-kriska/claude-elixir-phoenix --skill full -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/full, .gemini/skills/full, .github/skills/full and .opencode/skills/full in your project.

What does Full need to run?

Going by SKILL.md and its folder, Full needs the command-line tools its instructions call (claude).

Does Full access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Full safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Full use?

Full is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Full use?

About 2k tokens (SKILL.md is roughly 8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 3.3k tokens, read only when the agent opens those files.

What are the alternatives to Full?

Skills that share tags, products or a category with Full: Langfuse Codebase Navigator (langfuse/langfuse, 36k stars), LLM Trace Review Interface (ai-evals-course/evals-skills, 1.5k stars), Langfuse Integration Page (langfuse/langfuse-docs, 247 stars) and Langfuse (langfuse/skills, 300 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
