name	acp-local-runner
description	Run and debug Agmente ACP end-to-end scenarios from the repo-owned e2e/scenarios/acp specs. Use when validating ACP websocket compatibility, session creation, cwd handling, reconnect flows, or reproducing ACP-only UI failures against a real local ACP backend.

ACP Local Runner

Overview

Execute a repo-owned ACP scenario against a real local ACP backend, capture enough logs and UI state to diagnose failures, and always clean up backend and simulator app state.

For run, execute, validate, or reproduce requests, this skill is execute-only. Use real tools to perform the scenario; do not modify repository files unless the user explicitly asks to fix, stabilize, or make the flow executable.

Workflow

1. Resolve the scenario.

• Read the requested scenario from e2e/scenarios/acp/.
• If the user names no scenario, choose the closest match from that directory and state the choice.
• Treat the scenario file as the source of truth for setup, steps, assertions, and cleanup intent.

2. Resolve the backend.

• Read the backend id from the scenario front matter.
• Open the matching file in e2e/backends/.
• Use the backend file for canonical endpoint, start command, stop command, and capability notes.

3. Prepare execution.

• Prefer simulator execution when the scenario target is ios-simulator.
• Use XcodeBuildMCP tools when available for boot/build/run/log/screenshot/interaction.
• If simulator interaction tools are incomplete, use the best available non-editing fallback and state the limitation.
• Verify the backend is reachable before debugging app behavior.

4. Run the scenario.

• Follow the scenario steps in order.
• Capture wire or console checkpoints around initialize, session/list, session/new, session/prompt, session/load, and reconnect events when relevant.
• Use the scenario assertions and e2e/assertions/common.md to judge pass/fail.

5. Report and clean up.

• Report backend, endpoint, simulator target, scenario path, and pass/fail status.
• On failure, report the concrete broken step and the most likely root cause.
• Always stop the backend if this run started it.
• Always uninstall Agmente from the simulator unless the user explicitly asks to preserve state.

Guardrails

• Do not invent ACP behavior that is not in the scenario or backend docs.
• Do not make the skill the source of truth for scenario semantics.
• Prefer protocol-level explanations over tool-level explanations in failure reports.
• If the scenario and backend docs disagree, treat that as repo drift and report it.
• Treat run, execute, validate, and reproduce as execute-only requests.
• Agentic testing means actually running the backend, simulator, and relevant protocol tooling rather than describing manual steps.
• During execute-only runs, do not add accessibility identifiers, write harness code, patch docs, or create new tests to make the scenario pass.
• If the run is blocked by missing automation hooks or incomplete tooling, report the blocker and stop instead of editing the repo.
• Only make repository changes when the user explicitly asks to fix, stabilize, add hooks, or make the scenario executable.
