Verification before completion

ytstack:verification-before-completion

Thin wrapper around the vendored superpowers verification-before-completion skill (vendor/superpowers/skills/verification-before-completion/SKILL.md). Injects the current task's verification command extracted from the task-plan, then inlines the vendored procedure verbatim. Vendor is single source of truth.

ytstack invocation notes

The command(s) printed above are the current task's verification commands, extracted from the ## Verification section of the task-plan. These are what the vendored procedure must actually execute and confirm output of; do not substitute a different "looks like it should work" command.

HARD-GATE: if TASK_PLAN_EXISTS=no or VERIFICATION_CMD_FOUND=no, abort with: "No verification command in the active task-plan. Either run ytstack:plan-task to add one, or invoke this skill outside a ytstack task context where the user will provide the command." Do not invoke the vendored procedure without a command to verify.

After the vendored procedure completes:

• If verification passed: the user may now run ytstack:summarize-task.
• If verification failed: do NOT auto-retry. Report raw output and hand control back. The user decides next step (fix-and-retry vs re-scope the task).
