Conciseness

The body is lean, assumes competence, explains nothing Claude already knows, and pushes depth into references/. Minor trimmable redundancy remains: references/plugin-anatomy.md is linked twice (in the opening and again after the scaffold options), and a few sentences in the lint/security paragraphs run long. Efficient with minor over-explanation fits the 4 anchor, not the every-token-earns-its-place 5.

Actionability

Fully executable throughout: exact CLI invocations with required flags, the temporary-seed scaffold workaround as a copy-paste command, and a complete bash loop that asserts every intended file in the packed archive with fail-on-first-miss. Commands cover the common cases; matches the copy-paste-ready anchor.

Workflow Clarity

Six clearly ordered steps plus a 'When to stop' section, with explicit validation checkpoints: lint AND pack, per-file archive assertion with a nonzero exit on any miss, throwaway-install verification, and a security review gate. Feedback loops are present and concrete, matching the top anchor.

Progressive Disclosure

A ~96-line overview that cites all three real reference files (plugin-anatomy.md, shaping-and-decomposition.md, hooks-and-mcp.md) at the point of need, one level deep — the only cross-link inside the references is a sibling pointer, not a nested chain. Content is appropriately split with clear navigation.

Specificity

Enumerates multiple concrete actions — 'Scaffolds the plugin, authors or restructures the skills, and adds the rules, hooks, MCP servers, or commands' — covering the full primitive set the skill handles. This matches the comprehensive-coverage anchor rather than the minor-gaps anchor at 4.

Completeness

Explicitly answers both questions: 'Use once there is a confirmed composition plan' is a concrete when-trigger, and the what is a full enumeration of actions. Not 4, because the when is explicit and specific rather than weakly implied or generic.

Trigger Term Quality

Good domain keyword coverage ('plugin', 'skills', 'rules, hooks, MCP servers, commands', 'scaffold', 'composition plan'), but it lacks natural user-phrase variants a person might actually say (e.g. 'build the plugin', 'create the plugin'). Sits between the good-coverage (4) and comprehensive-synonym (5) anchors, closer to 4.

Distinctiveness Conflict Risk

The state-based trigger ('once there is a confirmed composition plan') carves a clear niche that distinguishes it from sibling planning, decomposition, and publishing skills; minimal conflict risk.
