name: full
description: "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."

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.

Cycle Limits

| Setting | Default | Description | |---------|---------|-------------| | `--max-cycles` | 10 | Max plan→review cycles | | `--max-retries` | 3 | Max retries per task | | `--max-blockers` | 5 | Max blockers before stopping |

Stop with INCOMPLETE status when limits exceeded. List remaining work and recommended action.
