Conciseness

The body contains no explanations of concepts Claude already knows; every sentence encodes framework-specific rules (injection-context reruns calling setOptions, resolving updaters with .update(next), store.get() vs atoms.<slice>.get()). It matches the lean anchor where every token earns its place, not 4, since there is no padding to trim.

Actionability

The controlled-signal setup is complete, executable TypeScript with correct imports, updater-function resolution, and a working component, and the API discovery section gives concrete node_modules paths to inspect. It matches the fully executable, copy-paste-ready anchor; the shared-atom case is explicitly routed to reactivity.md rather than left as a gap, so it is not the minor-gaps level of 4.

Workflow Clarity

This is a single-purpose skill whose entry action is unambiguous: "Load `intent load @tanstack/table-core#table-state` first", followed by clearly ordered sections (setup, reactive boundaries, task routing, API discovery). No destructive or batch operations exist, so no validation cap applies, and the simple-skill exception for a clear single action holds; there are no gaps that would place it at 4.

Progressive Disclosure

The body is a concise overview with a well-signaled, one-level-deep reference to references/reactivity.md (verified to exist), matching good structure with mostly appropriate placement. It is not 5 because two referenced paths are dangling in the actual bundle: ../getting-started/SKILL.md does not exist as a sibling and scripts/skill-snippets-angular.tsconfig.json referenced in the snippet comment is absent.

Specificity

"Read and control Table v9 state in angular" names the domain and actions, and "tracked reads, subscriptions, controlled slices" lists several specific capabilities, matching the anchor for several specific actions with minor gaps. It is not 5 because coverage is deliberately not comprehensive (initialization and reset rules are deferred to the table-core skill), and not 3 because more than 1-2 concrete actions are enumerated.

Completeness

It explicitly answers both what ("Read and control Table v9 state in angular") and when ("Use for tracked reads, subscriptions, controlled slices, and framework-specific reactive boundaries") with concrete trigger phrases, matching the top anchor. The explicit "Use for" clause with specific triggers keeps it above the 4 anchor, where the when-clause is present but could be more specific.

Trigger Term Quality

Natural terms a user would say are present ("Table v9", "angular", "state", "subscriptions", "tracked reads"), giving good keyword coverage. It falls short of 5 because common synonyms like "TanStack" and "signal" are missing, though it is well above the sparse keyword level of 3.

Distinctiveness Conflict Risk

The description carves a clear niche (Angular-specific Table v9 state, reactive boundaries) that is mostly distinct, but it overlaps with closely related sibling skills (table-core table-state, angular-table getting-started), matching the anchor for minor overlap risk rather than minimal conflict risk.
