Quality

Content

100%

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

The body is a tightly written, fully executable runbook with concrete commands, a clearly staged workflow, and explicit validation/stop conditions that assume Claude's competence without padding.

DimensionReasoningScore

Conciseness

The body is lean and operational — it assumes Claude's competence and contains no concept explanations or padding; every line is direct instruction such as 'Change only the ffmpeg-next.rev value' and 'Push once with git push -u origin HEAD'.

3 / 3

Actionability

It provides fully executable commands (cargo update -p ffmpeg-next, bun install --frozen-lockfile, bun run build-all, objdump -p ..., gh pr create --draft --body-file) with specific file paths and expected outputs, copy-paste ready.

3 / 3

Workflow Clarity

The sequence is clearly staged (Prepare worktree → Update Cargo and rebuild → Commit/push/PR → Finish) with explicit validation checkpoints — verify SHAs resolve in Cargo.lock, objdump MSVCRT check, git diff --check, and multiple 'stop and report' conditions.

3 / 3

Progressive Disclosure

Content is organized into clear sections with one-level-deep, clearly signaled references to sibling skills ([../pr/SKILL.md], [../pr-name/SKILL.md]); no bundle files exist and no nested references are used.

Description

85%

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

A strong, specific description with an explicit trigger clause and concrete actions; its only weakness is that the trigger language is narrowly tied to an internal chain rather than natural user phrasing.

Suggestions

Broaden the 'Use when...' clause to include natural user phrasing such as 'when updating FFmpeg/Rust-FFmpeg binaries in Remotion' alongside the chain reference.

Add common trigger variations (e.g. 'ffmpeg version bump', 'compositor binary rebuild') so users searching those terms land here.

DimensionReasoningScore

Specificity

The description lists multiple concrete actions — 'Update Remotion's ffmpeg-next Git revision', 'refresh Cargo.lock', 'rebuild all supported compositor binaries', 'validate the monorepo', and 'open a draft pull request' — matching the anchor for listing multiple specific concrete actions.

3 / 3

Completeness

It answers both 'what' (concrete update/rebuild/validate/PR actions) and 'when' with an explicit 'Use for the final step of the rust-ffmpeg binary update chain' clause, in third-person voice.

3 / 3

Trigger Term Quality

It includes relevant keywords like 'rust-ffmpeg', 'ffmpeg-next', 'Cargo.lock', and 'compositor binaries', but the trigger phrasing ('final step of the rust-ffmpeg binary update chain') is narrow and technical, missing common user-facing variations.

2 / 3

Distinctiveness Conflict Risk

The niche is very specific — Remotion's ffmpeg-next revision update chain — making it clearly distinguishable and unlikely to trigger for unrelated skills.
