The body is dense and project-specific — it assumes Claude knows Docker/s6 basics, never pads with generic explanations, and every section (architecture diagram, key-files table, recipes, pitfalls) carries unique operational detail that earns its tokens.

Recipes give fully executable `docker exec` commands with absolute paths and decoded expected outputs, and "Add a new static service" is a copy-paste-ready numbered list with exact file paths and contents — matching the executable-and-complete anchor.

Multi-step recipes (e.g. adding a static service) are clearly sequenced, the test harness recipe states an explicit checkpoint ("Expect 19 passed, 0 xfailed"), and a dedicated Common Pitfalls section provides error-recovery feedback loops for crash loops, perm errors, and exit 143.

Sections are well-organized with clear headers and a key-files table, but the skill is monolithic — no bundle files exist and everything (recipes, pitfalls, architecture rationale) is inline rather than split into one-level-deep reference files, so the well-signaled-references anchor for 3 is not met.

Lists multiple concrete actions — "Modify, debug, or extend", "adding new services", "debugging profile gateways", "understanding the Architecture B main-program pattern" — matching the anchor for enumerating several specific actions rather than a single vague one.

It clearly states what the skill does but never gives an explicit "Use when..." trigger clause; the "when" is only implied from the action list, so per the guideline it caps at 2.

It contains relevant domain keywords (s6-overlay, supervision tree, Docker image, profile gateways, services) but leans on internal jargon ("Architecture B main-program pattern") that a user would rarely say, missing common natural variations.

The niche is sharply scoped to the Hermes Agent Docker image's s6-overlay supervision tree, making it highly distinguishable and very unlikely to trigger for the wrong skill.
