Conciseness

The body is dominated by dense, token-efficient tables (partner scoring criteria, campaign format catalogs) and a copy-paste outreach template, with no explanation of concepts Claude already knows. It falls just short of a 5 because "When to Use This Skill" duplicates the frontmatter description, "Task-Specific Questions" repeats questions already asked in "Questions to identify partners", and a stray double '---' separator adds padding — but the waste is minor, so it is above anchor 3.

Actionability

For an instruction-only skill the guidance is fully actionable: a copy-paste-ready "Cold Outreach Template", a 1-5 partner scoring rubric with six concrete criteria, named data sources ("Crossbeam or Reveal", "G2/Capterra category neighbors"), a phased checklist, an 8-point agreement outline, and campaign catalogs covering the common cases by format/effort/best-for. Per the rubric's code_vs_instruction note, absence of code is not penalized; this matches anchor 5's 'specific examples cover the common cases'.

Workflow Clarity

Sections follow a logical end-to-end sequence (identify partners → brainstorm campaigns → approach → structure the partnership → measure success) and the phased "Co-Marketing Checklist" (Partner Identification → Campaign Planning → Execution → Post-Campaign) plus "What to Prepare for the Call" provide explicit sequencing with readiness checkpoints. Not a 5 because there are no explicit validation/error-recovery loops (e.g., what to do when a partner's audience overlap turns out smaller than Crossbeam suggested), though for a non-destructive strategy skill that gap is minor.

Progressive Disclosure

There are no bundle files (no references/, scripts/, or assets/), and the ~280-line body inlines reference-like catalog content — the four campaign-type tables, the outreach template, and the agreement outline are detailed material that could live in one-level-deep reference files with SKILL.md as an overview. Section headers and navigation within the document are good, which lifts it above anchor 2's unstructured inline wall, but 'content that should be separate is inline' matches anchor 3 rather than anchor 4's appropriately split structure.

Specificity

The description lists several concrete actions — "find co-marketing partners", "plan joint campaigns", "brainstorm partnership opportunities", "identify ideal partners" — scoped to the SaaS domain. It is not a 5 because the second sentence ("identify ideal partners and brainstorm high-impact campaigns") largely restates the first and the verbs remain fairly generic; it exceeds anchor 3 because more than 1-2 distinct concrete actions are named with clear domain coverage.

Completeness

Both questions are answered explicitly: 'what' via "Helps SaaS companies identify ideal partners and brainstorm high-impact campaigns" and 'when' via the leading explicit trigger clause "When the user wants to find co-marketing partners, plan joint campaigns, or brainstorm partnership opportunities". This matches the anchor-5 pattern of a clear 'what' plus concrete 'Use when'-equivalent trigger phrases, so it is above anchor 4 where the 'when' is only adequate.

Trigger Term Quality

Good natural keyword coverage: "co-marketing partners", "joint campaigns", "brainstorm partnership opportunities", "SaaS companies" — phrases a user needing this skill would plausibly say. Not a 5 because common synonyms and variations like "partner marketing", "cross-promotion", "joint launch", or "marketing collaboration" are missing; it clearly exceeds anchor 3's single-keyword example.

Distinctiveness Conflict Risk

The co-marketing/SaaS partnership niche is mostly distinct with clear triggers, but "partnership opportunities" and "brainstorm campaigns" leave minor overlap risk with closely related marketing skills (referral programs, product launches, content strategy). Not a 5 because the niche boundary is not sharply drawn against those adjacent skills; clearly above anchor 3 since the core triggers (co-marketing partners, joint campaigns) are specific.
