Vader Execution

Execute the current vader plan through a ralph-wiggum loop.

Step 1: Check Permissions

Run the permissions check:

"${CLAUDE_PLUGIN_ROOT}/scripts/check-permissions.sh"

If the output is NOT bypassPermissions, warn the user:

Vader works best with --dangerously-skip-permissions to avoid permission prompts interrupting the loop. Consider restarting with: claude --dangerously-skip-permissions

Ask if they want to continue anyway. If not, stop.

Step 2: Read Plan

Read the plan file:

.claude/vader/plan.local.md

If the file does not exist, tell the user to run /vader first and stop.

Step 3: Compose Prompt

Run the setup script to compose the ralph-wiggum prompt:

"${CLAUDE_PLUGIN_ROOT}/scripts/setup-exec.sh"

The output is the composed prompt text directly.

Step 4: Launch Ralph Loop

Read the max_iterations from the plan file frontmatter.

Try to invoke the ralph-wiggum loop using the Skill tool:

• skill: ralph-loop:ralph-loop
• args: <prompt-from-step-3> --max-iterations <max_iterations> --completion-promise 'Hurra Vader has Triumphed'

Fallback: Direct Execution

Drop to direct execution on any failure of the ralph-loop invocation: skill not installed, prompt parse error, runtime error, anything. When falling back, tell the user explicitly:

Falling back to direct execution (ralph-loop unavailable: ). The same per-milestone Executor → Verifier flow runs inline; only the iteration controller differs.

Don't silently retry. The failure mode of ralph-loop is opaque to the user; surfacing the reason makes it possible to fix.

In direct execution mode:

1. Read .claude/vader/plan.local.md for the full plan
2. Work through each milestone sequentially following the prompt instructions from Step 3
3. For each milestone: implement, test, lint/format, commit, update state file
4. After the LAST user milestone, run the Final Integration pass before declaring done:
   • Full test suite (whatever the project's test command is)
   • Full typecheck
   • Any project-level sanity scripts (npm run test:sanity, etc.)
   • Spawn a final Verifier with is_final: true
5. Only after Final Integration approves: update status to "done" and output <promise>Hurra Vader has Triumphed</promise>

The direct execution mode works identically to the ralph-wiggum loop but runs inline in the current session.
