Conciseness

The body is dense and procedural, assuming Claude's competence (e.g. "Convert every relative window to concrete absolute dates before searching") with no padding or explanation of known concepts. However, step 1 repeats ambiguity-handling guidance across overlapping bullets (two bullets both dictate offering the same explicit choices), which could be tightened. Not 5: some redundancy in the resolve-rep step; not 3: only minor trimming is needed.

Actionability

Fully concrete for an instruction-only skill: exact search parameters ("score_threshold=0", "limit of about 25 per slice"), concrete sample targets ("30-60 deduplicated calls", trailing 90 days in three slices), a copy-paste output format template, a literal citation example ("2026-03-24, ExampleCorp, Pilot & Pricing [1](https://example.com/call/123)"), and example prompts. Matches the 5 anchor.

Workflow Clarity

A clear five-step sequence with explicit validation and recovery loops: zero-result retry with grounded name variations, sparse-slice expansion, a dedicated small validation-fetch step, a Failure Handling section, and a fallback Limited Trend Readout mode. Matches the 5 anchor including error-recovery feedback loops.

Progressive Disclosure

References are well signaled and one level deep, both real files (references/request-schema.yaml, references/rubric.md), loaded conditionally with stated purpose ("Load references only when their extra detail matters"). Not 5: external links are malformed or unverifiable — "plugins/sales/skills/index/SKILL.md## Cross-Skill Best Practices" (space inside a heading-anchor link, outside the bundle) and "../index/SKILL.md#limitations-and-improvements" — which slightly impairs navigation.

Specificity

"Produce an evidence-backed trend readout with improvements, regressions, stable patterns, coaching actions, and calls to re-listen" enumerates multiple specific, concrete deliverables, comprehensively covering the skill's output. Not 4: there are no coverage gaps in the action list.

Completeness

Explicitly answers both: "Use when the user wants to understand how a sales or customer-facing rep's call behavior is changing over time" (when) and "Produce an evidence-backed trend readout with improvements, regressions, stable patterns, coaching actions, and calls to re-listen" (what). Matches the 5 anchor with concrete trigger phrasing; not 4 because the when-clause is explicit and specific.

Trigger Term Quality

Natural phrases like "rep's call behavior is changing over time", "trend", and "sales" are present, but common variations a user would naturally say (e.g. "coaching review", "call analysis", "how are my calls going") are missing. Not 5: synonym coverage is good but not comprehensive.

Distinctiveness Conflict Risk

The time-comparison framing ("changing over time", "trend") carves a distinct niche versus single-call review skills, but phrasings like "review a rep's calls" could overlap with sibling call-review or coaching-note skills. Not 5: minor overlap risk with closely related sales skills remains.
