Conciseness

The body is a lean routing table of one-line pointers plus dense operational rules; it explains nothing Claude already knows and every line carries actionable information (env vars, commands, gates). Fits the 'lean and efficient; every token earns its place' anchor.

Actionability

Copy-paste-ready commands with concrete arguments ('bin/lbs fixture check', 'bin/lbs suite start <suite-id>', 'bin/lbs test result <case-id>', 'bin/lbs suite report <suite-id> --evidence-dir <dir>'), exact env var names, and exact reference paths. Per the code-vs-instruction note, the absence of code in this instruction-only router is not penalized.

Workflow Clarity

The suite lifecycle (suite start → per-case test result → suite report), preflight-before-gate ordering, and explicit validation gates ('Do not mark a case pass until test result --evidence covers every value in evidence_required', 'A WebUI test is not complete until the visible UI result is checked against backend logs') give clear checkpoints. Not 5 because the overall workflow ordering is implied by scattered rules rather than an explicit sequenced overview, and error-recovery loops live in troubleshooting.md.

Progressive Disclosure

A clean overview routing to 15 clearly signaled, one-level-deep reference files, all verified to exist, with detail appropriately split into the references (~1500 lines total) and the body kept minimal. Matches the 'clear overview with well-signaled one-level-deep references' anchor.

Specificity

Enumerates multiple concrete actions ('Test LangBot WebUI and core product flows with an automated browser and backend logs', 'pipeline Debug Chat', 'model provider setup and test buttons', 'bot and knowledge-base UI flows', 'troubleshooting failed LangBot end-to-end tests') covering the skill's domain comprehensively; the 4 anchor would require minor coverage gaps, but the core flows are explicitly listed.

Completeness

Explicitly answers both 'what' (test LangBot WebUI and product flows with an automated browser and backend logs) and 'when' ('Use when validating the configured LangBot frontend... or troubleshooting failed LangBot end-to-end tests') with concrete trigger phrases, matching the 5 anchor.

Trigger Term Quality

Natural phrases users would say are present ('LangBot', 'WebUI', 'Debug Chat', 'test buttons', 'knowledge-base', 'end-to-end tests'), but several natural trigger areas from the skill's routing (plugin testing, MCP tools, runners, performance/reliability probes) are missing. Not 3 because the main use-case keywords are well covered; not 5 because coverage is not comprehensive.

Distinctiveness Conflict Risk

Clearly niche and LangBot-specific with named flows (pipeline Debug Chat, model provider test buttons, knowledge-base UI), so it is unlikely to trigger for the wrong skill; minimal overlap with generic testing skills.
