Conciseness

The body states 'Scripts do the work; this file lists only what differs from a plain Playwright recordVideo + ffmpeg job' and holds to it — every line is a non-obvious delta (deviceScaleFactor corner-frame gotcha, relay single-connection behavior, ~20x GIF size comparison, exit-code table). No padding and no explanation of concepts Claude already knows, matching the anchor-5 'every token earns its place' example.

Actionability

Every script has a concrete invocation in the table, plus a copy-paste example command ('node "${CLAUDE_SKILL_DIR}/scripts/finish.mjs" spec-1-1.webm spec-1-2.webm --out ...'), the exact screenshot call ('page.screenshot({ style: '#__screencast{display:none!important}' })'), an exact ffmpeg fallback command for the GIF path, and a complete exit-code table. Fully executable guidance covering the common cases matches anchor 5.

Workflow Clarity

Sequences are clear per mode (launch/start/step/stop for capture.mjs, overlay + per-step timings contract for runners), with an explicit validation checkpoint ('Read <id>.sheet.png before any upload or claim'), a feedback loop with fallback ('Exit 6 ... fall back to gif_creator, convert the GIF ... add a notes line'), and the mp4 sanity check surfaced via exit code 3. Anchor 5 fits; anchor 4 would require missing checkpoints, and the destructive/batch cap does not apply since recording is non-destructive.

Progressive Disclosure

Scored against the actual bundle: all four scripts referenced (scripts/record.mjs, overlay.js, finish.mjs, capture.mjs) exist, and the details the body defers are genuinely one level deep in those files ('schema in the file header' for record.mjs and 'Usage and exit codes in the file header' for capture.mjs both verified). The body is a lean overview table plus deviations, with clear links — matching the anchor-5 well-signaled one-level-deep structure.

Specificity

Lists multiple concrete actions — 'Records reviewable browser videos', 'a cursor, click ring, and step captions drawn on the page', 'dead waits cut, H.264 mp4 out, a per-step timings file and contact sheet' — plus three distinct input modes (scripted scene list, raw Playwright video, Chrome tab over the DevTools protocol). Coverage of the skill's capability surface is comprehensive, so it matches the anchor-5 example rather than anchor 4, which requires minor gaps.

Completeness

Both questions are answered explicitly: a detailed 'what' (overlay, trimmed H.264 mp4, timings file, contact sheet, three input modes) and an explicit 'when' clause with concrete trigger phrases ('Triggers on...'). This mirrors the anchor-5 example pattern exactly; anchor 4 would require the 'when' to be less explicit.

Trigger Term Quality

The explicit triggers ('record this interaction', 'screen recording', 'make a video of', '/screencast') are natural phrases users would say, but common variations like 'video recording', 'record a video of', or 'browser recording' are absent. Good coverage with a few natural terms missing fits anchor 4; it is above anchor 3 (only some relevant keywords) but below anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The description is well-scoped to browser recording (Playwright video, Chrome tab, DevTools protocol), but the trigger 'screen recording' is generic enough that an OS-level screen-capture request could match it. Mostly distinct with minor overlap risk against closely related recording skills fits anchor 4 rather than anchor 5's minimal-conflict niche.
