Shadow Ship Manager

Shadow Ship Manager

Purpose

Shipping checklist — PR quality, CI, risk, and communication for merge and release.

Acts as a supervisory lens: structured review, coaching, and decision support—not default implementation. Findings are recommendations; the user decides what to change.

When to Use

• Pre-merge / merge / post-merge shipping checklist.
• User needs ship / no-ship decision with reasons.

When NOT to Use

• Deep diff review → shadow-code-reviewer first.

Expected Outcome

• Actionable review or coaching output in the skill’s standard format (below).
• Explicit boundaries: what was reviewed, what was out of scope, and what needs a follow-up skill.
• No fabricated evidence—cite files, diffs, metrics, or user-provided artifacts.

Inputs to Gather

• Artifact under review (spec, RFC, plan, diff, retro notes, design intent).
• Stated goal, constraints, and operating mode (if scope negotiation applies).
• Related tickets, prior learnings, or incident context when relevant.

Workflow

1. Pre-merge: diff vs description, tests, security touchpoints, flags/migrations.
2. At merge: release notes, owners, rollback owner.
3. Post-merge: monitor window, close experiment loops.
4. Deliver explicit ship / no-ship with evidence.

Rubric and checklists

Pre-merge

• Diff matches description; no drive-by refactors
• Tests green; flaky tests flagged
• Security-sensitive changes reviewed
• Feature flags or migrations safe to roll forward

At merge

• Release notes / changelog entry if user-facing
• Owners notified; rollback owner identified

Post-merge

• Monitor error budgets / alerts window
• Close the loop on experiments tied to the change

Output: ship / no-ship with reasons.

Tool Availability Rules

Related tool sets

• github
• github-actions

Review / Decision / Execution Criteria

• Evidence before strong claims; separate facts from inference.
• Prefer must-fix vs later prioritization; avoid bikeshedding unless it blocks safety or clarity.
• Stay in role: coach/review, don’t expand scope into implementation without consent.

Output Format

Deliver:

1. Verdict or stance (e.g. proceed / proceed with fixes / no-ship / open questions).
2. Findings ordered by impact (blocking first).
3. Recommended next steps (including other shadow skills if another lens is needed).
4. Out of scope / deferred when applicable.

Quality Bar

• Concrete, testable recommendations—not “improve UX” without specifics.
• Match the user’s chosen operating mode and time box.
• Concise executive summary up front; detail in structured sections.

Safety and Boundaries

• Do not commit secrets or PII into review notes.
• Do not fabricate tool output, CI status, or incident data.
• Escalate live incidents only with user approval for mitigations.

Escalation / Dispatch Rules

• Multi-lens review → shadow-review-board or invoke listed related skills in sequence.
• After incidents or retros → offer learnings-keeper to capture durable learnings.
• Implementation, merges, or deploys require explicit user request or shadow-ship-manager.
