Conciseness

The body is a dense specification of non-derivable facts (discovery paths, regex constraints, size limits, reserved namespaces, diagnostic codes) with essentially no padding or explanation of concepts Claude already knows. Minor tightening is possible — e.g., the reserved-namespace rule for `vibe` is stated twice ('It must not be one of the reserved namespaces: ... vibe' and again in the following paragraph) — which keeps it below the 'every token earns its place' anchor.

Actionability

Every component type has a complete, copy-paste-ready example (plugin.json, the ai.mistral.vibe extension block, mcp.json, hooks.toml, KNOWLEDGE.md frontmatter, researcher.toml, libraries.json, connectors.json), and the rules give exact regexes, limits, and error behavior. A reader can author a valid plugin entirely from the provided artifacts.

Workflow Clarity

The closing Workflow section gives a clear 6-step sequence ('1. Determine the plugin name... 6. Tell the user to run /reload'), but no validation checkpoint exists — it never says to verify the plugin loads cleanly or to check the emitted diagnostics, even though the diagnostic-codes table is provided earlier. Steps are listed with an implicit-at-best checkpoint, matching the anchor for present sequence but missing validation.

Progressive Disclosure

The body is well organized with a discovery table, a directory-structure map, nine numbered step sections, a diagnostics table, and a compatibility table — navigation is easy and nothing is nested. However, it is a ~380-line single file with no bundle files; reference-grade material (the 19-row diagnostics table, the compatibility matrix, per-component limit rules) is inlined rather than split into one-level-deep reference files, which is a minor organization gap rather than a clear misplacement.

Specificity

'Create a Vibe plugin package — the Agent Plugins 1.0 format with optional Vibe extensions for skills, MCP servers, hooks, knowledge, agents, libraries, and connectors' comprehensively enumerates all seven component types, but the action verbs are limited to create/scaffold/author rather than multiple distinct concrete actions, placing it just below the comprehensive-actions anchor.

Completeness

It explicitly answers both questions: the 'what' is concrete ('Create a Vibe plugin package — the Agent Plugins 1.0 format with optional Vibe extensions for skills, MCP servers, hooks, knowledge, agents, libraries, and connectors') and the 'when' is explicit with concrete trigger phrases ('Use when the user wants to create, scaffold, or author a plugin for Mistral Vibe').

Trigger Term Quality

Natural trigger phrases are present — 'create, scaffold, or author a plugin' and 'Mistral Vibe' — giving good synonym coverage of how users would phrase the request. A few natural terms are missing ('build a plugin', 'make a plugin', 'extension'), so it falls short of the comprehensive synonym-and-extension anchor.

Distinctiveness Conflict Risk

The niche is clear and narrow — authoring plugin packages for Mistral Vibe specifically — with distinct triggers ('plugin', 'scaffold', 'Mistral Vibe') that few other skills would share, so conflict risk is minimal.
