shipping-and-launch

Prepares production launches. Use when preparing to deploy to production. Use when you need a pre-launch checklist, when setting up monitoring, when planning a staged rollout, or when you need a rollback strategy.

Content

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A thorough, highly actionable launch playbook with strong workflow sequencing and validation checkpoints for a risky operation. Its main weaknesses are mild redundancy in rollback guidance and a progressive-disclosure defect: referenced files are missing while their content is duplicated inline.

Suggestions

Create the four referenced files under references/ (or remove the See Also links) so the signaled navigation points to real content.

De-duplicate the inline Security, Performance, and Accessibility checklists against the referenced files so each lives in one place, keeping SKILL.md as the overview.

Consolidate the repeated rollback trigger conditions into a single source (e.g., the thresholds table) and trim the "Common Rationalizations" table to reduce token redundancy.

Dimension	Reasoning	Score
Conciseness	The checklists are dense and avoid explaining concepts Claude already knows, but rollback trigger conditions repeat three times (thresholds table, "When to Roll Back", and the rollback plan template) and the "Common Rationalizations" table is opinion padding that could be trimmed.	2 / 3
Actionability	Provides fully executable TypeScript examples (feature-flag check, ErrorBoundary, error middleware), concrete numeric decision thresholds, specific rollout percentages, and a copy-ready rollback plan template.	3 / 3
Workflow Clarity	The rollout is a clearly numbered six-step sequence with monitoring windows and an explicit "Advance only if all thresholds pass" checkpoint, plus a post-launch verification checklist and rollback steps with feedback loops for this risky operation.	3 / 3
Progressive Disclosure	Section organization is clear and the "See Also" block signals one-level-deep references, but the four referenced files (definition-of-done, security-checklist, performance-checklist, accessibility-checklist) do not exist and the Security/Performance/Accessibility content is duplicated inline rather than split out.	2 / 3

Description

90%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A well-constructed description with explicit third-person capability framing and strong, natural trigger coverage that clearly answers both what and when. The only weakness is that the capability statement is a single generic verb rather than a list of concrete actions.

Dimension	Reasoning	Score
Specificity	Names the domain ("Prepares production launches") but the what-clause is a single generic verb; the concrete actions (checklist, monitoring, rollout, rollback) appear only in the when-clause rather than as multiple stated capabilities.	2 / 3
Completeness	Explicitly answers both what ("Prepares production launches") and when via multiple "Use when…" clauses, satisfying the explicit-trigger requirement.	3 / 3
Trigger Term Quality	Natural, varied trigger terms an engineer would actually say are well covered: "deploy to production", "pre-launch checklist", "setting up monitoring", "staged rollout", and "rollback strategy".	3 / 3
Distinctiveness Conflict Risk	The production-launch/shipping niche with rollout, monitoring, and rollback triggers is distinct and unlikely to fire for unrelated skills.	3 / 3
