Dev Cancel

Dev Cancel

Derived from oh-my-claudecode (MIT, Yeachan Heo). Adapted for the EvoNexus Engineering Layer — simplified, runtime-free version.

Use When

• User says "cancel", "stop", "abort", "cancelomc", "stopomc"
• Multi-phase workflow (dev-autopilot, dev-deep-interview, dev-plan, dev-ralplan) is active and the user wants to exit
• Context indicates a long-running dev orchestration that needs a clean stop

Do Not Use When

• No engineering layer flow is active — just respond conversationally
• The user is canceling a single tool call (Claude Code already handles that)
• The user wants to pause/resume → use the workflow's own pause mechanism instead

Goal

Stop the active flow cleanly and give the user a structured summary of:

1. What was completed before cancel
2. What was in progress at cancel time
3. What was not started
4. Where the artifacts live (spec, plan, code) so the user can resume manually
5. Recommended next step

Workflow

1. Detect Active Flow

Look at recent context for signals:

• dev-autopilot was invoked → multi-phase pipeline active
• dev-deep-interview was invoked → interview loop active
• dev-plan was invoked → planning session active
• A @compass-planner, @bolt-executor, etc. agent was running

2. Stop the Flow

• Do NOT call any further agents
• Do NOT continue any in-progress phase
• Do NOT delete artifacts (specs, plans, partial code) — preserve for user inspection

3. Generate Cancel Report

Output this structure:

## Engineering Layer Cancel Report

**Flow stopped:** {dev-autopilot | dev-deep-interview | dev-plan | other}
**Stopped at phase:** {phase name}
**Reason:** {user request / error / explicit abort}

### Completed
- [phase 1: spec written → workspace/projects/specs/...]
- [phase 2: plan approved → workspace/projects/plans/...]

### In Progress (at cancel time)
- [phase X: implementing Y in file Z]

### Not Started
- [remaining phases]

### Artifacts Preserved
- Spec: `workspace/projects/specs/[C]autopilot-spec-{name}.md`
- Plan: `workspace/projects/plans/[C]autopilot-plan-{name}.md`
- Code changes: see `git status`

### Recommended Next Step
- "Resume manually": pick up from {phase} using {agent} directly
- "Re-run from scratch": delete artifacts and re-invoke `dev-autopilot`
- "Investigate first": review the artifacts before deciding

### Open Questions
[any unresolved decisions the flow was waiting on]

Rules

• Always preserve artifacts. Never delete spec/plan files on cancel — the user may want to resume.
• Never cascade cancels into business layer. Cancel only stops engineering flows; Clawdia/Flux/etc. routines keep running.
• Be explicit about what's incomplete. Don't claim partial work as done.
• Suggest the cheapest resume path — usually picking up from where the flow stopped, not restarting.

Failure Modes To Avoid

• Silent cancel: stopping without a report. Always emit the structured summary.
• Cleanup overreach: deleting artifacts the user might want.
• Continuing one more phase: "let me just finish this last bit". No — stop means stop.
• Vague status: "I stopped the workflow." → useless. Always include phase, completed work, and next step.
