name	implement-feature
description	Execute a SAM task plan (plan/tasks-*.md) by looping ready tasks, delegating each to its specified agent, and relying on hooks to update task timestamps/status. Use when a task file exists and you need to run the implementation loop that picks up ready tasks and delegates them to agents.

Implement Feature (SAM Workflow Execution)

This workflow continues from add-new-feature. It executes tasks from a SAM task file until complete (or blocked).

<feature_input> $ARGUMENTS </feature_input>

---

Resolve Task File

Rules:

• If $ARGUMENTS ends with .md, treat it as the task file path.
• Otherwise, treat it as a feature slug (or partial slug) and resolve via implementation_manager.py.

Example resolution:

uv run "${CLAUDE_PLUGIN_ROOT}/skills/implementation-manager/scripts/implementation_manager.py" \
  status "${CLAUDE_PROJECT_DIR}" "$ARGUMENTS"

---

Progress Loop

1. Query status:

uv run "${CLAUDE_PLUGIN_ROOT}/skills/implementation-manager/scripts/implementation_manager.py" \
  status "${CLAUDE_PROJECT_DIR}" "$ARGUMENTS"

2. If tasks remain, query ready tasks:

uv run "${CLAUDE_PLUGIN_ROOT}/skills/implementation-manager/scripts/implementation_manager.py" \
  ready-tasks "${CLAUDE_PROJECT_DIR}" "$ARGUMENTS"

3. For each ready task:

• Route to the agent named in the task's **Agent** field.
• Launch the agent with a prompt that invokes start-task:

Skill(skill="python3-development:start-task", args="{task_file_path} --task {task_id}")

4. Repeat until no tasks remain ready.

---

Completion Gate

When all tasks show COMPLETE, invoke:

Skill(skill="python3-development:complete-implementation", args="{task_file_path}")
