Conciseness

The body is lean and command-driven with no padding or explanations of concepts Claude already knows; even the prose passages (integration-tests rationale, add-mount idempotency note) each earn their place.

Actionability

It provides fully executable bash with concrete flags, a real idempotent jq snippet, and explicit file paths with clearly marked <group-id> placeholders — copy-paste ready rather than pseudocode.

Workflow Clarity

A clear 5-step sequence with per-step Verify checkpoints and a Troubleshooting feedback loop covers the container-restart and config-mutation risk, matching the 'explicit validation steps with error recovery' anchor.

Progressive Disclosure

A single self-contained, well-sectioned SKILL.md with no bundle files; under the simple-skill note, clear organization without external references earns the top score.

Specificity

Names concrete actions ('Install rtk token-compression proxy', 'Routes Bash tool calls through rtk') and enumerates specific dev commands (git, cargo, pytest, docker, kubectl), matching the 'multiple specific concrete actions' anchor rather than the less comprehensive level 2.

Completeness

It clearly answers 'what does this do' (install and route Bash calls for token savings) but 'when to use it' is only implied with no explicit trigger clause, which the guidelines cap at 2.

Trigger Term Quality

Relevant technical terms are present but they lean toward tool listing rather than natural user phrasing, and there is no 'Use when...' clause to surface common variations a user would actually say, so it sits at 'some relevant keywords but missing common variations'.

Distinctiveness Conflict Risk

The rtk-in-agent-containers niche with specific Bash-tool-call routing is distinct and unlikely to trigger for unrelated skills, matching the 'clear niche with distinct triggers' anchor.
