Conciseness

The body is lean and efficient: a compact executable setup block, terse Wrong/Correct mistake entries, and no explanation of concepts Claude already knows. Every section earns its tokens, matching anchor 5; there is no padding that would drop it to anchor 4.

Actionability

The Setup section is complete, executable TypeScript covering the common case, and API Discovery gives concrete file paths. However, the Devtools host provisioning step defers to 'docs/devtools.md' without showing how, and the 'table: undefined' / 'enabled' function behavior has no code example — minor gaps that fit anchor 4 rather than the fully copy-paste-ready anchor 5, and clearly above anchor 3 since the code shown is real and executable.

Workflow Clarity

The overall flow (setup code, host note, injection-context/key/isDevMode pitfalls) is clear and the single action is largely unambiguous, matching the simple-skill pattern. But the host-provisioning step is mentioned after the component code and is underspecified, leaving a minor gap that fits anchor 4; this is a non-destructive registration task so the validation cap at 3 does not apply.

Progressive Disclosure

The body is well-sectioned (Setup, Hooks and Components, Common Mistakes, API Discovery) and self-contained with no nested references. At roughly 70 body lines it exceeds the under-50-lines simple-skill exception, and the 'docs/devtools.md' pointer is a source-repo path rather than a clearly signaled bundle file — good structure with minor organization gaps, matching anchor 4 rather than anchor 5.

Specificity

Names the concrete action ('Register Angular Table v9 instances with injectTanStackTableDevtools') plus several specific capability topics (reactive registration, required options.key, enabled/undefined tables, cleanup, isDevMode gating, production exports). Several specific items with minor coverage gaps — the Devtools host provisioning step is not mentioned — so it sits at anchor 4 rather than a fully comprehensive 5 or the sparser 1-2-action level of 3.

Completeness

Explicitly answers 'what' ('Register Angular Table v9 instances with injectTanStackTableDevtools inside injection context') and 'when' with an enumerated 'Load for...' clause listing six concrete trigger conditions. The when-clause is explicit and specific, matching the anchor 5 example's structure rather than anchor 4's 'could be more explicit.'

Trigger Term Quality

Good keyword coverage of terms a user of this package would naturally say (devtools, table registration, cleanup, isDevMode, production exports), but natural phrasing variations like 'add devtools to an Angular table' or the package name itself are missing, keeping it below the comprehensive anchor 5 and clearly above the sparse anchor 3.

Distinctiveness Conflict Risk

Highly niche (Angular + TanStack Table v9 + named inject function + isDevMode gating) with distinct trigger conditions; virtually no overlap risk with other skills. This clearly matches anchor 5's 'clear niche with distinct triggers' rather than anchor 4's 'minor overlap risk.'
