Conciseness

The body is dense and almost entirely repo-specific (paths, invariants, key names) with no explanation of concepts Claude already knows, matching "efficient; minor instances that could be trimmed". The ~30-line Response Metadata section with its provider table is detail that could partly live in the implementation guide, keeping it below the lean-everywhere anchor 5.

Actionability

Guidance is fully concrete: exact file paths (ddtrace/llmobs/_contrib/<name>/, ddtrace/llmobs/_integrations/utils.py), real identifiers (_annotate_llmobs_span_data(), _openai_finish_reason_metadata(), submit_to_llmobs), a field checklist table, and provider-specific finish_reason sources with merge/omit/join rules. Per the instruction-only scoring note, absence of code is not penalized when guidance is this actionable, and the common cases are covered.

Workflow Clarity

The body is organized by concern (ownership/references, invariants, extraction checklist, metadata rules) rather than as an ordered create-or-modify sequence, and validation checkpoints are absent from the body itself — running the LLMObs test suites is only implied via the testing-guide reference. This matches "sequence present but checkpoints missing or implicit"; it is not 2 because the invariants and checklist impose substantial structure, and not 4 because no explicit step order or verification step appears in the body.

Progressive Disclosure

The body is an overview whose four links (implementation-guide.md, failure-modes.md, testing-guide.md, nova-sonic.md) all exist in references/, are one level deep, and are labeled and routed with "Read only the reference relevant to the change". Implementation detail, failure fixes, and test commands are appropriately split into those files, matching the well-signaled one-level-deep anchor; the single cross-skill pointer in implementation-guide.md delegates shared content to the owning apm-integrations skill rather than nesting this bundle's content.

Specificity

"Create or modify LLMObs integration lifecycle, extraction, streaming, usage metrics, and tests" names the domain plus several concrete action areas (lifecycle, extraction, streaming, metrics, tests), matching the "several specific actions; minor gaps" anchor. It falls short of 5 because the actions are aspect-level labels rather than fully elaborated concrete actions, and above 3 because coverage goes beyond 1-2 actions.

Completeness

The "what" is clear (create or modify integration lifecycle, extraction, streaming, usage metrics, tests) but there is no "Use when..." clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. It is not 2 because the "what" is specific rather than vague.

Trigger Term Quality

Terms like "LLMObs integration", "extraction", "streaming", "usage metrics", and "tests" are natural phrases a user working on this domain would say, giving good keyword coverage. Not 5 because common synonyms and variations (e.g., "LLM observability", "tracing", "spans", "datadog", "token usage") are missing.

Distinctiveness Conflict Risk

"LLMObs" pins a clear niche with distinct triggers, but the generic word "integration" creates minor overlap risk with the closely related apm-integrations skill that the body says covers the same contrib patching. Not 5 due to that recognized overlap; not 3 because the LLMObs qualifier makes confusion unlikely.
