Quality

Content

88%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is an actionable, well-sequenced operational runbook: concrete commands, a real bundled helper script with its interface documented, explicit validation and review checkpoints, and clear error-recovery guidance for a risky public-publishing workflow. Its only weaknesses are minor: a stray time-sensitive date and some detailed browser-fallback procedure that could live in a separate reference file.

DimensionReasoningScore

Conciseness

The body is dense and prescriptive with essentially no explanation of concepts Claude already knows, but "As checked on 2026-10-08..." is time-sensitive information outside a deprecated/old-patterns section and a few legalistic sentences could be tightened, so it sits at the efficient-with-minor-trims anchor.

4 / 5

Actionability

Fully executable commands are provided (prepare-release.py invocation with flags, SKILLS_ROOT=... validate-links.ts, bun run --cwd packages/agent-plugin test) alongside exact dashboard URLs, named buttons, and a concrete fallback file-picker procedure — copy-paste ready and covering the common cases.

5 / 5

Workflow Clarity

A clear sequence (inspect current release → prepare ZIP → validate → upload → follow review → publish → verify Publication Version) is given with explicit validation checkpoints and error-recovery feedback loops such as "fix the staged package and recreate it", "inspect the version list before retrying", and "Do not keep uploading the same ZIP to retry pending scans".

5 / 5

Progressive Disclosure

Sections are well organized and the single bundle script (scripts/prepare-release.py, verified to exist with a matching CLI interface) is referenced one level deep with its behavior documented; however, at ~125 lines with the detailed Chrome native-picker fallback inlined rather than split into a reference file, there are minor organization gaps.

Description

75%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific, concrete, and highly distinctive within a well-defined niche, covering the full update workflow from ZIP preparation to publication. Its main weakness is the absence of any explicit "Use when..." trigger guidance, which limits discoverability when the user's request does not already name the plugin. Adding a trigger clause with natural phrasings would raise both completeness and trigger-term coverage.

Suggestions

Add an explicit trigger clause such as "Use when a new Remotion version is released and the published Codex/ChatGPT plugin needs updating, or when the user mentions publishing or updating the Remotion plugin in the OpenAI directory."

Include a few more natural user phrasings (e.g. "plugin store", "marketplace listing", "new Remotion release") to improve trigger-term coverage.

Optionally state the boundary of what this skill does not cover (e.g. local `codex plugin add` installs) to further reduce overlap with related skills.

DimensionReasoningScore

Specificity

"Prepare the ZIP from the official Codex plugin repository, preserve its listing metadata, and upload and publish through OpenAI Platform" lists four concrete actions covering the entire update workflow, matching the comprehensive-coverage anchor rather than the minor-gaps anchor at 4.

5 / 5

Completeness

The "what" is clearly stated (update, prepare, preserve, upload, publish), but there is no "Use when..." clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines.

3 / 5

Trigger Term Quality

Natural terms like "Update", "Remotion", "Codex", "ChatGPT", "plugin", "publish", and "release" are present, but a few natural phrasings a user might say (e.g. "marketplace", "plugin store", "new Remotion version") are missing, fitting the good-but-incomplete keyword anchor.

4 / 5

Distinctiveness Conflict Risk

The description names one specific plugin (Remotion's Codex/ChatGPT directory plugin), its repository, and OpenAI Platform as the publishing channel — a clear niche with distinct triggers and minimal conflict risk with other skills.
