Conciseness

The body is lean — Operating Rules, a short Workflow, Known Stable Facts, and a Resources pointer — with no explanation of concepts Claude already knows; every section carries non-obvious domain detail (error-code meanings, byte patterns, file paths). Matches the score-3 'every token earns its place' anchor; not score 2 because there is no padded or unnecessary explanation to tighten.

Actionability

Quotes executable commands such as "uv run python -m modules.trae_patch.trae_native_sse_open_url_rewriter --help" and concrete scripts like "scripts/trae_patch/trae_native_byte_pattern.py", plus the literal byte pattern "48 8b 52 08 4d 8b 46 10 48 8d 8d 20 01 00 00" and call offset "0x0F". Matches the score-3 'fully executable commands; specific examples' anchor; not score 2 because guidance is concrete rather than pseudocode.

Workflow Clarity

Quotes a sequenced diagnostic flow: "1. Classify the failure before changing code" with an error-code table, then confirm path, then reproduce with smallest surface, then route to references on Trae-update or prior-approach uncertainty. The 'classify before changing code' gate and reproduce commands act as checkpoints; not score 2 because the sequence is explicit and gated rather than a bare step list.

Progressive Disclosure

The body is an overview that signals two one-level-deep references inline ("read references/update-recovery.md", "read references/native-route-map.md") and again in a Resources section; both files exist in ./references/ and are not nested further. Matches the score-3 'well-signaled one-level-deep references' anchor; not score 2 because content is appropriately split rather than inlined.

Specificity

Quotes "Maintain, debug, and recover MTGA's Trae native custom-model route" plus "needs diagnosis" — multiple concrete actions (maintain, debug, recover, diagnose) tied to a specific named route, matching the score-3 anchor that lists several specific concrete actions; not score 2 because it goes beyond naming only a domain and a couple of actions.

Completeness

Quotes the explicit "Use when ..." trigger clause plus the what-statement "Maintain, debug, and recover ... route", so both what it does and when to use it are explicit; not score 2 because the when is stated explicitly rather than merely implied.

Trigger Term Quality

Quotes "Use when Trae native integration fails, Trae updates shift ai_agent.dll hook offsets, errors such as 4028/4054/429 appear" — these are the exact terms a user of this domain would say (error codes, "Trae native", "ai_agent.dll"); not score 2 because coverage spans several natural trigger scenarios rather than a single keyword.

Distinctiveness Conflict Risk

Quotes "MTGA's Trae native custom-model route" with narrow triggers (specific error codes, ai_agent.dll offsets) — a clear niche unlikely to fire for unrelated skills; not score 2 because the scope is highly specific rather than broadly overlapping.
