shipping-and-launch

Prepares production launches. Use when preparing to deploy to production, or when asking what needs to be in place before shipping. Use when you need a pre-launch checklist, when setting up monitoring, when planning a staged rollout, or when you need a rollback strategy.

Quality

Content

77%Weight 40%Scale 1-5

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

The body is highly actionable, with concrete numeric rollout thresholds, an advance/hold/roll-back decision table, a fill-in rollback plan template, and explicit validation checkpoints around a risky operation. It is held back by boilerplate error-handling code Claude already knows, a duplicated after-deploy verification section, and a See Also section whose four reference links point to files that are absent from the bundle.

Suggestions

Fix or remove the See Also links: the four ../../references/*.md files (definition-of-done, security-checklist, performance-checklist, accessibility-checklist) are not in this bundle — either include them in a references/ directory (one level deep, inside the skill) or delete the links so navigation does not dead-end.

Cut the ~40-line boilerplate ErrorBoundary/Express error-middleware example and the trivial feature-flag snippet, keeping only the project-specific reporting payload fields — Claude already knows standard error-handling patterns.

Merge the trailing 'Verification' section into 'Post-Launch Verification'; both enumerate the same after-deploy checks (health check 200, error rate, latency, logs, rollback readiness), so the duplication costs tokens without adding information.

DimensionReasoningScore

Conciseness

The majority of the body is dense and earns its place (checklists, threshold tables, rollout sequence, error-budget gates), but there is real waste: a ~40-line boilerplate React ErrorBoundary and Express error middleware Claude already knows, a trivial feature-flag React snippet, and a trailing 'Verification' section that largely repeats 'Post-Launch Verification'. This is more than the 'minor instances' of anchor 4 but the padding is localized rather than pervasive, so anchor 3 fits better than anchor 2.

3 / 5

Actionability

Guidance is fully concrete: exact rollout percentages ('5% → 25% → 50% → 100%'), a numeric decision table ('Within 10% of baseline', '>2x baseline', '>50% above baseline'), a ready rollback plan template with the command 'git revert <commit> && git push', named audit tools ('npm audit, pip-audit, cargo audit'), and complete TypeScript/Express snippets. Specific examples cover the common launch cases, matching anchor 5; it is clearly above anchor 4's 'minor gaps'.

5 / 5

Workflow Clarity

The staged rollout is a clearly numbered 6-step sequence with explicit validation checkpoints ('Advance only if all thresholds pass (see table below)', '24-48 hour monitoring window'), feedback loops ('Ability to roll back to previous percentage at any point'), immediate rollback triggers, and before/after-deploy verification checklists. This matches anchor 5 (explicit validation, error-recovery feedback loops, checklists for a complex process); destructive-risk operations here are well covered by validation, so no cap applies.

5 / 5

Progressive Disclosure

The body is well-sectioned and the 'See Also' section clearly signals references, but the four cited paths ('../../references/definition-of-done.md', 'security-checklist.md', 'performance-checklist.md', 'accessibility-checklist.md') do not exist anywhere in the bundle — the skill ships only SKILL.md with no references/ directory, so the links dead-end. Additionally, the Security/Performance/Accessibility checklists are inlined even though the See Also claims dedicated files exist for them, i.e. content that should be separate is inline — anchor 3's pattern. It is above anchor 2 (structure here is strong, references are not buried) but below anchor 4 because the navigation pointers are broken.

Description

83%Weight 40%Scale 1-5

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 strong description with an explicit, multi-trigger 'Use when...' clause covering deploy, ship, checklist, monitoring, rollout, and rollback scenarios, and a clear if terse 'what'. Its only weaknesses are the single-clause 'what' side and a few missing natural synonyms ('release', 'go-live'), plus slight trigger overlap with an observability-type skill on 'setting up monitoring'.

DimensionReasoningScore

Specificity

The description names several concrete capabilities — 'pre-launch checklist', 'setting up monitoring', 'planning a staged rollout', 'rollback strategy' — though they are framed as when-clauses while the what-side is a single generic clause ('Prepares production launches'). This lands between anchor 3 (1-2 concrete actions) and anchor 5 (comprehensive what-side enumeration): several specific actions are listed with minor coverage gaps, so 4 fits best.

4 / 5

Completeness

Both questions are answered explicitly: what ('Prepares production launches') and when ('Use when preparing to deploy to production... when you need a pre-launch checklist, when setting up monitoring, when planning a staged rollout, or when you need a rollback strategy') with multiple concrete trigger phrases. The 'Use when...' clause is present and highly specific, matching the anchor 5 example's structure; it is clearly above anchor 4, whose 'when' is generic.

5 / 5

Trigger Term Quality

Natural phrases a user would say are well covered: 'deploy to production', 'shipping', 'pre-launch checklist', 'monitoring', 'staged rollout', 'rollback strategy'. A few common synonyms are missing ('release', 'go-live', 'canary'), which matches anchor 4 (good coverage, a few natural terms missing) rather than anchor 5's comprehensive synonym coverage.

4 / 5

Distinctiveness Conflict Risk

The launch/deployment niche is clear and triggers are anchored to that context ('before shipping', 'pre-launch', 'staged rollout'), giving minimal conflict with most skills. The 'setting up monitoring' trigger overlaps a likely observability-related skill (the body itself cross-references 'observability-and-instrumentation'), which is minor overlap with a closely related skill — anchor 4 rather than 5.
