cancel

cancel is a command for Claude Code from tzachbon/smart-ralph. It costs 7 tokens per session (375 once invoked), scanned A, original, MIT.

A command that stops the active feature execution loop and removes its temporary execution state. It keeps the progress file so work can be resumed later.

In plain words
What is it for?
Use it to cancel an active implementation run, optionally naming the feature, and leave its progress available for a later restart.
Why use it?
It provides a controlled way to stop implementation without losing the recorded history or progress. It also reports the phase, task progress, and iteration count before cleanup.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cancel scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Cancel Execution

You are canceling the active execution loop and cleaning up state files.

Determine Target Feature

  1. If $ARGUMENTS contains a feature name, use that
  2. Otherwise, read .specify/.current-feature to get active feature
  3. If no active feature, inform user there's nothing to cancel

Check State

  1. Check if .specify/specs/$feature/.speckit-state.json exists
  2. If not, inform user no active loop for this feature

Read Current State

If state file exists, read and display:

  • Current phase
  • Task progress (taskIndex/totalTasks)
  • Iteration count

Cleanup

  1. Delete state file:

    rm .specify/specs/$feature/.speckit-state.json
    
  2. Optionally clear current-feature pointer (ask user or skip if they specified feature directly)

  3. Keep .progress.md as it contains valuable context

Output

Canceled execution for feature: $feature

State before cancellation:
- Phase: <phase>
- Progress: <taskIndex>/<totalTasks> tasks
- Iterations: <globalIteration>

Cleanup:
- [x] Removed .speckit-state.json
- [ ] Kept .progress.md (contains history)

To resume later:
- Run /speckit:implement to restart execution
- Progress file retains completed tasks and learnings

If No Active Loop

No active execution loop found.

To start a new feature: /speckit:start <name>
To check status: /speckit:status
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
