Quality

Content

75%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A solid, well-structured tool reference that is highly actionable and free of conceptual filler. Its main gaps are the absence of worked examples for the most common calls and a lifecycle workflow that must be assembled by the reader from separate sections.

Suggestions

Add a short worked example of the most common flow: a yao_daemon_start call with command, description, and port, followed by the port_detecting response and the eventual running status with daemon_url.

Consolidate the redundant port-detection prose: the intro paragraph ('Both modes start by returning port_detecting with daemon_port: 0...') duplicates the two mode bullets; keep only the mode-specific details.

Present the daemon lifecycle as one numbered sequence (start with port → poll yao_daemon_status → use daemon_url from the BackgroundJobReceipt → yao_daemon_restart on crash → yao_daemon_stop when done) instead of distributing it across Tools, Response Fields, and Usage Rules.

DimensionReasoningScore

Conciseness

The body is a dense, tool-specific reference with no padding about concepts Claude already knows ('All responses are JSON. Daemon objects contain...', param tables, error codes). However, the port-detection intro paragraph ('Both modes start by returning port_detecting with daemon_port: 0...') restates what the two mode bullets immediately re-detail, and the daemon_url field description repeats the port-verification phrasing.

4 / 5

Actionability

Concrete and executable throughout: exact parameter tables with defaults ('limit | 20', 'working_dir | workspace'), enumerated response fields, error codes, and explicit polling instructions ('Poll yao_daemon_status until status changes to running'). Falls short of 5 because there are no worked examples of the most common operations (a start call with command/description/port, or a status response body), only list/stop/error JSON samples.

4 / 5

Workflow Clarity

The port-detection flow is clearly sequenced with explicit expected outcomes and failure modes ('with daemon_port: 0 and detail: specified port N not detected within timeout (~60s)'), which is a real validation checkpoint. Not 5 because the overall daemon lifecycle (start → poll status → use daemon_url → stop/restart) is scattered across Tools, Response Fields, and Usage Rules rather than presented as one coherent sequence.

4 / 5

Progressive Disclosure

Well-organized sections (Tools, Parameters, Response Fields, Errors, Usage Rules, BackgroundJobReceipt) with a flat, navigable structure and no buried or nested references. It is not 5 because at ~95 lines the full response-field enumeration and the detailed port-detection behavior are candidates for a separate reference file, and the body exceeds the simple-skill threshold where inline-only content would be fully appropriate.

Description

83%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description with a clear what/when pair and natural trigger phrasing. It is held back from excellence only by the slightly generic 'monitor' verb and minor trigger-term and overlap gaps around 'dev servers'.

DimensionReasoningScore

Specificity

Names the domain and four concrete actions ('start, monitor, restart, stop long-running services'). This matches anchor 4 ('several specific actions; minor gaps') rather than 5 because 'monitor' is generic and concrete capabilities like reading daemon output or port/URL reporting are not mentioned.

4 / 5

Completeness

Explicitly answers both questions: the 'what' ('Daemon process management — start, monitor, restart, stop long-running services') and a concrete 'when' ('ALWAYS invoke this skill when the user asks to start, check, restart, or stop background services, dev servers, or daemon processes'), exactly matching anchor 5.

5 / 5

Trigger Term Quality

Good natural-phrase coverage across verbs and nouns users would say ('start, check, restart, or stop', 'background services, dev servers, or daemon processes'). Not 5 because common variations like 'kill', 'is the server running', or 'logs' are missing, so it sits at anchor 4 ('good keyword coverage; a few natural terms missing').

4 / 5

Distinctiveness Conflict Risk

Clear niche (daemon/background-service lifecycle) with distinct triggers, but 'dev servers' overlaps with project run/deploy skills, matching anchor 4 ('mostly distinct; minor overlap risk') rather than anchor 5's minimal-conflict profile.
