Conciseness

The body is lean reference material — tool sequences, parameter lists, and pitfalls — assuming Claude's competence without explaining known concepts. Minor over-explanation and redundancy keep it below the 5 anchor: pitfalls are repeated between workflow sections and the 'Known Pitfalls' section, and the closing 'When to Use' section ("This skill is applicable to execute the workflow or actions described in the overview.") is empty filler that earns nothing.

Actionability

Concrete, executable guidance throughout: exact tool slugs (MIRO_GET_BOARDS2, MIRO_CREATE_ITEMS_IN_BULK), parameter names, enum values ('viewer', 'commenter', 'editor'), and hex color formats. Below the 5 anchor because no concrete request/payload examples are shown and several details are deferred to 'check current schema', leaving minor gaps for a copy-paste-ready standard.

Workflow Clarity

Sequences are clearly ordered with prerequisites (resolve board_id via GET_BOARDS2, confirm connection ACTIVE before workflows), but the skill includes batch operations (MIRO_CREATE_ITEMS_IN_BULK) and outward-facing actions (MIRO_SHARE_BOARD) with no validation/verification steps after execution — no verify-created-items or confirm-membership checks. Per the rubric guideline, batch operations without validation cap workflow clarity at 3; the otherwise solid sequencing keeps it from dropping lower.

Progressive Disclosure

Good structure with well-organized sections (Prerequisites, Setup, five Core Workflows, Common Patterns, Known Pitfalls, Quick Reference) and no nested references — appropriate for a single-file skill that defers live schemas to RUBE_SEARCH_TOOLS. Below the 5 anchor because at ~210 lines the per-workflow detail and the Quick Reference table duplicate content that could be split into a separate reference file, leaving minor organization gaps.

Specificity

The description names a concrete domain ("Miro tasks via Rube MCP (Composio)") and lists several specific capability areas ("boards, items, sticky notes, frames, sharing, connectors"), plus an explicit behavior directive ("Always search tools first for current schemas"). It falls below the 5 anchor because it lists objects rather than comprehensive concrete actions (e.g., no 'create boards, add sticky notes, share boards' verbs), leaving minor coverage gaps.

Completeness

The 'what' is clear (automate Miro board/item/sticky-note/frame/sharing/connector tasks), but there is no 'Use when...' clause or equivalent trigger guidance — the second sentence ("Always search tools first for current schemas") is an agent instruction, not a trigger. Per the rubric guideline, a missing 'when' clause caps completeness at 3; it is not 4 because the 'when' is entirely absent rather than merely imprecise.

Trigger Term Quality

Strong natural keywords: "Miro", "boards", "sticky notes", "frames", "sharing", "connectors" — terms a user asking for Miro help would naturally say. Below the 5 anchor because common variations like "whiteboard", "collaborate", or tool synonyms are missing, so a few natural trigger phrases are absent.

Distinctiveness Conflict Risk

"Miro" pins a clear niche with minimal conflict risk, and terms like "sticky notes" and "frames" reinforce it. Below the 5 anchor because generic whiteboard vocabulary ("boards", "sharing", "sticky notes") could still overlap with other whiteboard/collaboration skills, and no explicit trigger phrases sharpen the boundary.
