## Description

Use when about to claim work is complete, fixed, passing, verified, release-ready, or ready to commit, merge, publish, or hand off.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

<EXPLICIT-MODE-GATE>
If `activation_mode = "explicit"` or `AEGIS_ACTIVATION_MODE=explicit` is visible
and the request names neither Aegis nor this skill, return to the fast path
without checklist/ceremony; otherwise continue.

# Execute

Before success claim: classify destructive permission; read sufficient current
evidence and run a fresh falsifying check when it is missing or invalidated;
read the complete result/scope; select L0/L1/L2. Downgrade for partial,
stale, failing, or narrower evidence; never claim complete then verify later.

This pack grants no `GateDecision`, `PolicySnapshot`, evidence sufficiency,
requirement acceptance, or completion authority.

## Stop Signals

- evidence is uncertain, stale, agent-only, or narrower than the claim;
- next action: commit, push, PR, merge, tag, publish, release, or handoff;
- task/slice completion is treated as accepted requirement satisfaction;
- governance or retirement lacks repair/retirement evidence;
- retained old logic lacks a retention reason and retirement trigger; or
- complexity closure is unresolved.

Destructive/irreversible work needs scoped permission; broad assent is not scoped permission.

## Required Evidence Slots

For changed interface/interaction claims, compose `ui-ux-governance` verification;
carry results and uncovered user criteria here, keeping one closeout owner.

```text
- Evidence action / check performed:
- Result / exit status:
- Covered scope:
- Uncovered scope:
- Residual risk:
- Confidence grade: A | B | C
```

- `A`: target + regression; no meaningful unknown.
- `B`: target evidence; bounded residual risk.
- `C`: partial only; no full-completion claim.

For repairs/optimization, distinguish cause, closure and verified outcome.
Check interactions and preserved behavior; investigate consequential unknowns.
