testland/killswitch-test-author

Workflow-driven skill that authors the four test categories specific to kill-switch (ops-toggle) flags: switch-OFF graceful degradation, fail-static default when the flag service is unreachable, latency budget for the kill decision, and no-data-corruption mid-flight. Distinct from flag-state-coverage-builder (which builds a full coverage matrix across all flag types) and feature-flag-test-matrix-reference (which catalogs patterns without producing tests). Use when a kill-switch flag exists in the codebase and needs dedicated, production-incident-rehearsing tests authored for it.

Quality

Content

85%

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

A thorough, actionable skill with executable patterns, a clear four-step workflow, and well-organized inline content. The only weakness is conciseness: several block quotes from external docs restate SDK fundamentals Claude already knows.

Suggestions

Replace the verbatim OpenFeature/LaunchDarkly documentation block quotes in Categories 2 and 3 with a one-line statement of the operative rule (e.g., 'On evaluation error the SDK returns the configured default — assert the default and that the app does not throw') to cut tokens.

Trim the streaming-vs-polling/TTL explanation in Category 3 to the single actionable takeaway, leaving the URL as a reference rather than a quoted paragraph.

DimensionReasoningScore

Conciseness

Mostly efficient, but several long verbatim block quotes from external SDK documentation (e.g., the OpenFeature and LaunchDarkly quotes in Category 2 and the streaming/TTL explanation in Category 3) restate SDK behavior Claude largely already knows and could be trimmed to the operative rule.

2 / 3

Actionability

Each of the four categories ships a concrete, executable TypeScript test pattern using real APIs (TestData, OpenFeature), plus a complete copy-paste-ready example test file at the end.

3 / 3

Workflow Clarity

The four test categories are explicitly sequenced in order with per-category assertion patterns, an anti-patterns table mapping failures to fixes, and a Limitations section flagging where verification is incomplete (Category 3 staging smoke test).

3 / 3

Progressive Disclosure

No bundle files are present, so all guidance lives inline in SKILL.md; it is well-organized into Overview, When/How to use, per-category sections, an example file, anti-patterns, limitations, and a one-level-deep References list of external doc links.

Description

100%

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 highly specific, well-triggered description that clearly states what the skill does, when to use it, and how it differs from two named sibling skills. No vagueness or over-claims.

DimensionReasoningScore

Specificity

Names concrete actions — "authors the four test categories specific to kill-switch (ops-toggle) flags" — and enumerates all four (switch-OFF graceful degradation, fail-static default, latency budget, no-data-corruption mid-flight).

3 / 3

Completeness

Explicitly answers both what (authors four test categories) and when ("Use when a kill-switch flag exists in the codebase and needs dedicated, production-incident-rehearsing tests authored for it").

3 / 3

Trigger Term Quality

Natural trigger terms present — "kill-switch flag exists in the codebase", "ops-toggle", "feature-flags", "production-incident-rehearsing tests" — matching what a user needing this skill would say.

3 / 3

Distinctiveness Conflict Risk

Explicitly distinguishes from siblings by name — "Distinct from flag-state-coverage-builder... and feature-flag-test-matrix-reference" — carving a clear, non-overlapping niche.
