The body is dense with proprietary daemon-contract detail Claude would not know (managed-family semantics, free_port mutex, port-mismatch and runtime-binding guards, DOCKER_CONFIG scoping, container-uid cache derivation) and contains no padding about basic concepts like containers or Docker, matching the 'lean and efficient; every token earns its place' anchor. Not 2 because the length is justified by genuinely non-obvious operational density rather than unnecessary explanation.

Provides a fully executable register() call with all parameters and a complete bash start script (create_service, port-mismatch guard, warm/cold branching, runtime-binding guard) that is copy-paste ready, matching the 'fully executable code/commands' anchor. The only placeholders (<image from the runbook>, <cache target from the runbook>) are explicitly justified because the runbook skill supplies them, so it is not penalized as pseudocode.

The registration and lifecycle flow is clearly sequenced (free_port -> register -> daemon start -> readiness route -> cell) with explicit validation checkpoints (live='/v1/health/ready', port-mismatch guard, docker port check) and error-recovery feedback loops (FAILED is sticky -> Stop or byte-identical re-register; stuck stop -> out-of-band recovery), matching the 'clear sequence with explicit validation steps; feedback loops for error recovery' anchor. Not 2 because checkpoints are explicit, not implicit.

No bundle files exist; the single SKILL.md is organized into clear sections and defers detail to clearly-named sibling skills one level deep ('the model's own runbook skill', 'use the using-model-endpoint skill (that one documents the call side in full)'), matching the 'clear overview with well-signaled one-level-deep references; easy navigation' anchor. Not 2 because references are clearly signaled and the inline start script is the core contract, not content that should be split out.

Names multiple concrete actions — 'Read the runbook, allocate a port (local only), compose idempotent start/stop scripts (local only), register once' — matching the 'lists multiple specific concrete actions' anchor; it is above 2 because the action list is comprehensive, not merely 'some actions'. Voice is third-person imperative, so no person-penalty applies.

Explicitly answers 'what' (the registration contract: 'Register a model service... compose idempotent start/stop scripts... register once') and 'when' ('Load when the user wants a model service available for inference, or when list_compute shows managed endpoints'), matching the 'clearly answers both what AND when with explicit triggers' anchor. Not capped at 2 because an explicit 'Load when' trigger clause is present.

An explicit 'Load when...' trigger exists, but the keywords lean on internal jargon ('managed family', 'list_compute', 'managed endpoints') and omit common user phrasings like 'serve/run a model' or 'model server', matching the 'some relevant keywords but missing common variations' anchor. Not 3 because coverage is jargon-heavy; not 1 because a natural-ish trigger phrase ('wants a model service available for inference') is present.

Occupies a narrow named niche — daemon-owned 'managed family' model endpoints with distinctive triggers ('when list_compute shows managed endpoints') — making conflict with unrelated skills unlikely, matching the 'clear niche with distinct triggers' anchor. Not 2 because the managed/daemon framing is specific rather than merely 'somewhat specific'.
