Conciseness

The body is dense and substantive — it never explains concepts Claude already knows and each step carries real instruction — but it repeats the registry-proposal protocol four times (Scope guard, Writes, step 8, Save Results) and restates the red lines that also live in channel-matrix.md. This is 'efficient with minor instances that could be trimmed' (4), not the every-token-earns-its-place leanness of the 5 anchor; it is clearly above 3 since there is no padded or unnecessary explanation.

Actionability

Guidance is concrete for an instruction-only skill: exact artifacts per platform, exact file paths (memory/launch/community-launch-runner/..., memory/events/launches.ndjson), an exact title format ("Show HN: <what it is, stated plainly>"), and a specified per-sub table schema. It falls short of fully copy-paste-ready (5) because there is no worked example of a submission package or a sample registry-events.py propose invocation — the reader must assemble the shape from prose. It is well above the 3 anchor's pseudocode-level incompleteness.

Workflow Clarity

Eight explicitly sequenced steps with validation checkpoints and error feedback loops: step 1 gates on a manifest-matching SHIP verdict ("Missing accepted state or a mismatch is Unknown/NEED_INPUT; do not submit against it"), step 2 drops channels whose rules bar self-promotion and says to ask moderators when ambiguous, and step 8 enforces receipt evidence before any status fact is proposed ("partial, failed, missing, or unknown receipts remain open"). This matches the 5 anchor — explicit validation, error-recovery behavior, and a 'Done when' checklist; the destructive/batch cap does not apply because validation is present.

Progressive Disclosure

The body is a well-signaled overview that delegates the channel detail to a real one-level-deep file ([channel-matrix.md](references/channel-matrix.md), verified present in the bundle) listed in a Reference Materials section. It misses 5 because many cross-links (skill-contract.md, CONNECTORS.md, SECURITY.md, ramp-benchmark.md, launch-registry, action-control.md) point outside this bundle and do not resolve from it, leaving navigation partly dangling; structure is still clearly better than the 3 anchor's buried or inline-heavy organization.

Specificity

The description enumerates comprehensive concrete outputs: "a Product Hunt tagline / gallery / first-comment skeleton, a factual Show HN title and text, per-subreddit posts with a self-promotion rules table, tiered directory waves, and a regional channel matrix including Chinese communities — plus a platform red-line check... and T-0 submission-status lines". This matches the 5 anchor (multiple specific concrete actions, comprehensive coverage); it is well above the 4 anchor because there are no meaningful coverage gaps in the skill's output surface.

Completeness

It explicitly answers both questions: what ("produces per-platform submission packages... a platform red-line check... T-0 submission-status lines") and when ("Use when the user asks to..." with three concrete quoted trigger phrases), plus explicit non-goals. This matches the 5 anchor exactly; the 4 anchor ('when could be more explicit') clearly undersells the quoted trigger phrasing present.

Trigger Term Quality

It quotes natural user phrasings directly ("launch on Product Hunt / Hacker News", "prepare community or directory launch submissions", "plan the launch submission waves") and covers synonyms including Show HN, subreddits, directories, and Chinese keywords (社区发布/PH提交包/Show HN/目录波次/平台红线/中文渠道). This is comprehensive natural-term coverage per the 5 anchor, not merely 'good coverage with a few missing' (4).

Distinctiveness Conflict Risk

It carves a clear niche (community/directory submission execution) and actively disambiguates four adjacent skills ("Not for paid amplification — use content-amplifier; not for creator channels — use campaign-planner; not for launch telemetry readouts — use launch-monitor; not for ongoing community presence... use participation-warmup-planner"). Minimal conflict risk, matching the 5 anchor.
