Conciseness

Nearly every sentence carries SDK-specific knowledge Claude does not have (no concept-teaching padding), but the same failure-mode rules are restated three to four times each — the load_chat_model deletion rule appears in the warning block, Stage 2 sub-step 1, the 'What NOT to Do' section, and Edge Cases; the /configs-targeting fallthrough rule and the once-per-turn tracker rule are similarly repeated. This fits the score-3 anchor ('mostly efficient but could be tightened'); it avoids score 2 because the verbosity is redundancy of high-value content, not generic explanation or fluff.

Actionability

Executable Python and Node snippets (SDK init, fallback constructors, tracker wiring, judge guards), exact package names with version floors, before/after diffs, and exact guard idioms ('if judge and judge.enabled') — copy-paste-ready and covering the common cases, matching the score-5 anchor. The few partial snippets (commented agent-mode example) are clearly flagged as shape illustrations with pointers to full worked examples in references.

Workflow Clarity

Five explicitly ordered stages with sequencing rationale ('Wrap before you add tools...'), a hard STOP checkpoint after the read-only audit with four explicit response forms, and a verification sub-step at every stage including fallback-path testing with an invalid SDK key — a clear sequence with explicit validation and error-recovery feedback loops, the score-5 anchor. The hand-off model (prepare inputs, wait for the user to run the sibling skill) is stated unambiguously and reinforced in 'What NOT to Do'.

Progressive Disclosure

All six references/*.md files cited in the body exist in the bundle, are one level deep, are linked with section-level anchors, and are indexed both in a References section and a coverage-tier matrix — good structure per the score-4 anchor. It falls short of score 5 because the 570-line body inlines substantial detail duplicated from the reference files (Edge Cases table, three-failure-mode warnings), and many links point into a sibling skill outside this bundle (../built-in-metrics/...) which cannot be resolved from the bundle itself.

Specificity

The description enumerates five concrete migration stages — 'audit the code, wrap the call, move the tools, add tracking, attach evaluators' — giving comprehensive, specific coverage of the action surface, matching the score-5 anchor. No gaps in the action list; it is not merely 'several specific actions' with minor gaps (score 4).

Completeness

It explicitly answers both 'what' (the five named stages of the migration) and 'when' via a concrete 'Use when the user wants to...' clause with three distinct trigger conditions — the exact shape of the score-5 anchor. The 'when' is explicit and specific, so it exceeds the score-4 anchor where the trigger clause could be more specific.

Trigger Term Quality

Good natural-term coverage: 'externalize model/prompt configuration', 'move from direct provider calls (OpenAI, Anthropic, Bedrock, Gemini, Strands) to a managed config', and 'hardcoded-to-LaunchDarkly migration' are phrases users would actually say. A few natural variants (e.g. 'move prompts out of code', 'prompt migration') are missing, so it fits the score-4 anchor rather than the comprehensive score-5 anchor.

Distinctiveness Conflict Risk

It names a specific product (LaunchDarkly AgentControl) and migration-specific triggers (externalize config, hardcoded-to-LaunchDarkly migration), forming a clear niche with minimal conflict risk against other skills — the score-5 anchor. It is far more distinct than the 'mostly distinct, minor overlap' score-4 example.
