otel-ottl

OpenTelemetry Transformation Language (OTTL) expert for writing and debugging telemetry transformations in the OpenTelemetry Collector. Use when authoring or reviewing `transform`, `filter`, `tail_sampling` processor configs or `routing` connector configs, debugging OTTL syntax or semantics, transforming traces, metrics, logs, or profiles, or converting data-processing requirements into OTTL statements.

Quality

Content

100%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is an exemplar of a reference-backed skill: concise, fully actionable with executable OTTL and exact identifiers, a validation-gated workflow, and clean one-level-deep progressive disclosure into three verified reference files.

DimensionReasoningScore

Conciseness

Lean, dense body that assumes Claude's competence—no 'what is OTTL' padding, version pinned once, terse bullets for traps—every token earns its place, matching anchor 5.

5 / 5

Actionability

Provides copy-paste-ready OTTL ('set(span.attributes["env"], "prod") where resource.attributes["env"] == nil'), exact identifiers ('Decode(value, "base64")', 'Substring', 'truncate_all'), concrete path syntax ('span.cache["parsed"]', 'spanevent.*'), and specific YAML-escaping rules ('$${1}'), covering common cases per anchor 5.

5 / 5

Workflow Clarity

Five-step numbered workflow with explicit validation checkpoints ('Verify every emitted function, then write the statement'; 'Verify end to end... inspect file-exporter output') and a referenced end-to-end verification recipe, matching the anchor 5 sequence with feedback loops.

5 / 5

Progressive Disclosure

Clear overview pointing to three real, one-level-deep, well-signaled references (contexts.md, functions.md, quick-reference.md) with per-file descriptions; full catalogs are split out and all referenced paths exist, matching anchor 5.

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is highly specific, complete, and distinctive, with explicit 'what' and 'when' clauses and concrete component-level triggers. Its only mild weakness is a trigger surface that leans on technical config jargon over the most colloquial user phrasings.

DimensionReasoningScore

Specificity

Lists multiple concrete actions—'writing and debugging telemetry transformations', 'authoring or reviewing transform/filter/tail_sampling processor configs', 'debugging OTTL syntax or semantics', 'transforming traces, metrics, logs, or profiles'—with comprehensive coverage, matching the anchor 5 example.

5 / 5

Completeness

Explicitly answers 'what' ('OTTL expert for writing and debugging telemetry transformations in the OpenTelemetry Collector') and 'when' ('Use when authoring or reviewing...') with concrete trigger phrases, matching anchor 5.

5 / 5

Trigger Term Quality

Good keyword coverage of natural trigger terms (transform, filter, tail_sampling, routing, traces/metrics/logs/profiles, OTTL syntax), but the trigger surface leans somewhat on technical component/config jargon and omits a few natural phrasings, fitting anchor 4 rather than the fully comprehensive anchor 5.

4 / 5

Distinctiveness Conflict Risk

Occupies a clear, narrow niche (OTTL for specific Collector processors/connectors) with distinct triggers and minimal overlap risk with other skills, matching anchor 5.
