Conciseness

The body is lean — concrete CLI commands, an exact JSON contract, and specific risk categories with no padded explanations of what security or LLMs are; the only mild extras (the "Plan §6.2" pointer and the parenthetical v1 non-goal) are brief, so it sits at the level-3 lean-and-efficient anchor rather than the could-be-tightened level 2.

Actionability

Provides copy-paste-ready executable commands with all flag variants and exit codes (`bin/hephaestus security scan <agent-folder> --strict --acknowledge-warn`) plus an exact output-file contract; the judgment guidance lists concrete risk types and required fields, matching the level-3 executable-and-complete anchor rather than the pseudocode level 2.

Workflow Clarity

Stage 1 and Stage 2 are clearly sequenced with explicit validation checkpoints (re-run the scan to merge the judgment, gate on the combined verdict) and a feedback loop for WARN (show findings → user approves or fixes → proceed) plus a BLOCK stop-and-fix path, satisfying the level-3 clear-sequence-with-validation anchor; not level 2 because checkpoints and error recovery are explicit, not implicit.

Progressive Disclosure

No bundle files exist (references/scripts/assets are all absent) and the skill is self-contained, organized into well-labeled sections (Stage 1, Stage 2, CLI, Output) with one-level-deep inline content; per the simple/self-contained skill guideline this earns the level-3 well-organized anchor rather than the structure-could-improve level 2.

Specificity

Names concrete actions and the scan's components — "pass the Agentlas Cloud 2-stage security scan (static rules + BYOK LLM judgment)" and "run/interpret `hephaestus security scan`" — rather than vague abstractions; closest to the anchor listing multiple specific concrete actions, not the domain-only level 2.

Completeness

Explicitly answers both what (pass the 2-stage security scan) and when ("Use when an agent folder must pass... or when asked to run/interpret `hephaestus security scan`") with an explicit trigger clause, matching the level-3 what-and-when anchor rather than the when-only-implied level 2.

Trigger Term Quality

Includes natural trigger terms users would say ("security scan", "private sync or public publish", "run/interpret hephaestus security scan") with good coverage of the relevant phrasings; it goes beyond a single keyword toward the level-3 natural-term coverage.

Distinctiveness Conflict Risk

Targets a very specific niche — the Agentlas Cloud security scan and the `hephaestus` CLI — with distinct triggers unlikely to fire for unrelated skills, matching the clear-niche level-3 anchor.
