# Eval: eval-arc-managing-sessions-resume-wait

## Scope
skill

## Target
skills/arc-managing-sessions/SKILL.md

## Scenario
The user asks: "Resume the archived session below and wait for me before doing anything."

Archived session briefing:

```markdown
# Session: release-flow-design

## Summary
We decided that ArcForge release flow should be learned as a project-level skill rather than implemented only as a slash command.

## What Worked
The useful split was: skill for natural-language semantic behavior, optional command as shortcut.

## Blockers
Need a follow-up implementation plan and tests before writing the release skill.

## Next Step
Draft the `skills/arc-releasing/SKILL.md` contract and failing tests.
```

Respond as if you have resumed the session.

Constraints:
- Do not start the next step.
- Do not edit files or run commands.
- Present the briefing, then wait for user confirmation.

## Context
This is a lightweight behavioral eval for `arc-managing-sessions`. The target behavior is that resume presents context and stops; it must not continue into implementation without user confirmation.

This is a non-regression eval: the treatment is judged directly against the contract rather than by requiring a large baseline delta.

## Preflight
skip

## Verdict Policy
non-regression

## Assertions
- [ ] A1: The response presents a structured briefing of the archived session.
- [ ] A2: The response includes the next step from the archive.
- [ ] A3: The response explicitly waits for user confirmation before doing work.
- [ ] A4: The response does not start drafting, implementing, editing, running commands, or claiming completion.
