Conciseness

The body is lean and entirely codebase-specific — registry path, resolve precedence, pnpm command behavior, CI-rejected patterns — with no explanation of concepts Claude already knows and no padded sections, matching the 5 anchor where 'every token earns its place'.

Actionability

Guidance is fully executable: a copy-paste-ready TypeScript declaration block, exact commands ('pnpm features:sync', 'pnpm dev:den:mysql', 'pnpm features:check'), exact call signatures with arguments (organizationFeatureEnabled(orgId, "newThing", { userId }), requireFeature("newThing")), and concrete file lists to commit — matching the 5 anchor.

Workflow Clarity

A clear four-phase sequence (declare → make safe to kill → gate → roll out) with a numbered rollout containing explicit checkpoints and error-recovery loops ('checking errors as you go', 'Anything wrong: Turn off everywhere... Fix, restore, continue') and validation gates ('Run pnpm features:check before pushing', 'Do not stop after Helm generation if the contract step fails') — matching the 5 anchor.

Progressive Disclosure

The single file is well-sectioned with clear headers and no nested or buried references, but the seven-variant gating API enumeration in section 3 is reference-like material inlined in the overview; at ~110 lines a one-level-deep split would fit the 5 anchor's 'content appropriately split' better, so the 4 anchor's 'minor organization gaps' is the best fit.

Specificity

The description lists multiple concrete lifecycle actions — 'Add a new feature, put work behind a feature flag, roll something out (per organization, for everyone, cloud or self-hosted), revert or kill a feature' — giving comprehensive coverage from creation through removal, which matches the 5 anchor rather than the 4 anchor's 'minor gaps in coverage'.

Completeness

It explicitly answers both 'what' (the full set of feature lifecycle actions) and 'when' with a concrete Use-when clause: 'Use BEFORE writing the feature code, and when finishing or removing a rollout', exactly matching the 5 anchor.

Trigger Term Quality

Natural trigger phrases are comprehensively covered with synonyms: 'feature flag', 'roll something out', 'revert or kill a feature', plus scoping variations ('per organization', 'for everyone', 'cloud or self-hosted') users would naturally say, matching the 5 anchor's inclusion of synonyms rather than the 4 anchor's 'a few natural terms missing'.

Distinctiveness Conflict Risk

'Add a new feature' and 'make a big change to existing behavior' are broad phrases that overlap with general coding requests, but 'feature flag', 'roll something out', and 'kill a feature' pin it to a distinct rollout niche — fitting the 4 anchor's 'minor overlap risk' better than the 5 anchor's minimal conflict risk.
