Conciseness

The body is ~875 lines with heavy padding and outright duplication: context detection and banner instructions appear twice (the EXECUTION CONTRACT Steps 1-2 and again under "Deliver Workflow - Deliver Phase"), banner templates are printed three times, and Example 1 embeds a ~120-line fully worked validation report. This is noticeably below the midpoint — several padded, removable sections — though it stops short of score 1, which is reserved for extensively explaining concepts Claude already knows rather than duplication.

Actionability

Most guidance is executable: exact script invocations ("${HOME}/.claude-octopus/plugin/scripts/orchestrate.sh deliver \"<user's validation request>\""), a runnable provider check, a complete validation-gate block that locates the results file, and a full PR-posting bash block. It falls short of 5 because some blocks are illustrative rather than executable (the spinner-progress prose, the fill-in report templates) and variables like $VALIDATION_FILE must be threaded across separate blocks; it is well above 3 since no pseudocode stands in for real commands.

Workflow Clarity

The EXECUTION CONTRACT lays out a clearly sequenced 7-step process with explicit validation checkpoints (Step 5 verifies the validation file exists, failure branches are enumerated in Error Handling, and a Validation Checklist closes the loop). It misses 5 because the duplicated second workflow section restates the steps with conflicting numbering ("Implementation Instructions" lists 5 steps vs. the contract's 7), which muddies the authoritative sequence rather than sharpening it.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent), and everything is inlined in one ~875-line SKILL.md — including the ~120-line example validation report, the dev-subtype supplement table, and the PR-posting script block, all of which clearly belong in separate reference files. There are section headers, so it rises above the no-structure example of score 2's low end, but the inlining of large self-contained chunks with no one-level-deep reference files fits 'content that clearly belongs in separate files is inlined' better than score 3's 'some structure, could be better organized'.

Specificity

The description names the domain ("Multi-AI validation") and a few actions ("validation, scoring, and review using available external providers"), but the actions are generic verbs with no stated objects — it never says what is validated or reviewed (code, documents, PRs). It matches 'names domain and 1-2 concrete actions, but not comprehensive' rather than score 4, whose example lists several specific actions with concrete targets; it is above score 2 because more than one action and the provider mechanism are named.

Completeness

The 'what' is stated ("Multi-AI validation, scoring, and review using available external providers") but the 'when' is missing — there is no 'Use when...' clause or equivalent trigger guidance; "Double Diamond Deliver phase" is plugin jargon, not an explicit trigger. Per the judging guideline, a missing 'Use when...' clause caps completeness at 3, which this squarely fits.

Trigger Term Quality

It contains relevant natural terms users would say — "validation", "review", "scoring" — but misses common variations and synonyms ("code review", "audit", "quality check", "validate implementation", file types). Not score 4: coverage lacks the broader natural phrasing users actually use; not score 2: more than one or two relevant keywords are present alongside the domain.

Distinctiveness Conflict Risk

"Multi-AI validation ... using available external providers (Double Diamond Deliver phase)" carves out a fairly distinct niche (multi-provider orchestration within this plugin's Double Diamond flow), with mostly minor overlap risk against generic single-model review skills. It is below score 5 because broad words like "review" and "validation" with no 'use when' scoping could still collide with plain review requests; it is above score 3 because the multi-AI/external-provider framing is more distinctive than a generic 'works with document files' style description.
