Conciseness

The body is dense and assumes competence — it never explains what OTel or a collector is, and all explanatory prose covers non-obvious domain knowledge (silent nil behavior, OR vs AND conditions, pipeline ordering) rather than padding, so every token earns its place.

Actionability

Provides multiple complete, copy-paste-ready YAML snippets (error_mode config, ParseJSON body promotion, keep_keys cardinality reduction, extract_sum_metric/extract_count_metric, SHA256 redaction) with specific contexts and functions covering the common cases.

Workflow Clarity

The 'Debug an OTTL statement' workflow is a clearly sequenced 7-step process with a diagnostic feedback loop (Collector message → root cause → first action via the Error patterns table) and an explicit gate ('Only then propose the corrected statement'); no destructive batch operation cap applies.

Progressive Disclosure

Six real reference files in references/ are signaled inline at each relevant concept (→ [references/...md]) and listed in a References footer with one-line descriptions; structure is one level deep, well-organized, and easy to navigate, with the body acting as a true overview.

Specificity

Lists multiple concrete actions — context selection, path expression mistakes, error_mode, cardinality reduction with keep_keys, JSON body handling with ParseJSON, PII redaction with SHA256/replace_pattern, and span naming — giving comprehensive coverage rather than just several with minor gaps.

Completeness

Explicitly answers both what (OTTL transforms/filters/routes telemetry via the listed capabilities) and when ('Use when writing or debugging OTTL statements in the transform processor, filter processor, or routing connector'), with concrete trigger phrases and explicit negative triggers.

Trigger Term Quality

Includes natural phrases a user would say ('writing or debugging OTTL statements', 'transform processor', 'filter processor', 'routing connector', 'cardinality', 'PII redaction') with synonyms and function names, matching the comprehensive natural-term coverage anchor.

Distinctiveness Conflict Risk

Occupies a clear niche (OTTL inside OTel Collector pipelines) and explicitly excludes infra problems (receiver/exporter connectivity, DNS, pipeline wiring), minimizing overlap with adjacent skills.
