The body is mostly efficient operational guidance, but the intro delivery-architecture paragraph ('forks a detached wait-and-deliver background process via subprocess.Popen(..., start_new_session=True)') exposes implementation internals Claude does not need, and the 'Never do these', 'Pre-Generation Check', and 'Mandatory Guard Checklist' sections overlap. It is not a 3 because of that redundant/over-explained material, and not a 1 because it does not explain concepts Claude already knows.

Commands like 'python3 scripts/libtv_video.py create-session "user's video description" --channel feishu --chat-id ou_333...' and the full command-reference table are executable and copy-paste ready. It is not a 2 because the examples are complete with real argument values, not pseudocode.

'Pre-Generation Check (must run before each generation)', 'After Submission', and the 'Mandatory Guard Checklist' give a clear sequence with explicit validation checkpoints and feedback loops ('If any guard check fails, stop and return the explicit guard-check error'). It is not a 2 because checkpoints are explicit, not merely implicit.

The two bundle scripts (scripts/libtv_video.py, scripts/feishu_send_video.py) are correctly externalized and their paths are real, but the ~315-line SKILL.md is monolithic — the command-reference table, error-handling table, and URL rules are inline where a separate reference file would help. It is not a 3 because content that could be split is inline, and not a 1 because sections are well organized and references are accurately signaled.

Lists multiple concrete actions — 'AI text-to-video, image-to-video, video continuation, style transfer, and text-to-image' — matching the 'lists multiple specific concrete actions' anchor. It is not a 2 because the action enumeration is comprehensive rather than partial.

It states what the skill does ('text-to-video, image-to-video, video continuation, style transfer, and text-to-image') and gives explicit when-guidance via the 'Trigger phrases:' clause, which is equivalent trigger guidance. It is not a 2 because the when is explicit, not merely implied.

'Trigger phrases: seedance, generate video, make a video, generate image, make an image, draw, libtv, liblib' are natural phrases a user would say. It is not a 2 because common natural variations are well covered, not just one or two.

'Seedance 2.0 video & image generation via LibTV Gateway' with distinct triggers (seedance, libtv, liblib) carves a clear niche unlikely to conflict with other skills. It is not a 2 because the routing and brand terms make overlap with generic generation skills unlikely.
