Conciseness

The body is largely lean — commands, real JSON payloads, and terse operational guidance that assumes CLI competence without explaining basic concepts — but the E2M compute model is duplicated between the body and references/e2m-schemas.md, and a few lengthy caveat passages could be tightened, so it stops short of fully lean.

Actionability

Copy-paste-ready throughout: exact `cx` commands and flags, real JSON shapes (v5 custom-table `file.textual`, `requestEnrichments` with `enrichmentType` as objects, jq pipelines), and precise gotchas like "must use requestEnrichments not enrichments" cover the common cases fully.

Workflow Clarity

Four numbered workflows each sequence clearly with verification checkpoints ("Verify Parsing", "Verify Enriched Fields", "Verify the metric", "Verify with PromQL") and a troubleshooting loop for no-series E2M, plus an ordered cost-optimization workflow that verifies the E2M before downgrading TCO; the minor gap is that bulk-delete and delete lack an explicit pre-deletion confirm/list feedback loop.

Progressive Disclosure

Well-organized sections with a single one-level-deep reference (references/e2m-schemas.md, a real file) clearly signaled via markdown links and described, and related skills plainly listed; the only organization gap is the partial duplication of the E2M compute model between body and reference rather than a clean split.

Specificity

Several concrete actions are named across the trigger phrases — "extract fields from logs", "enrich logs", "create metric from logs", "recording rule", "transform log data" — plus a closing capability clause "configure how Coralogix processes, enriches, or transforms ingested data", but they are embedded in quoted triggers rather than a clean leading capability list, so it falls just short of comprehensive.

Completeness

Both "what" and "when" are present and explicit — the abundant "Use this skill when the user asks to..." clause answers when with concrete triggers, and the trailing clause answers what — but the capability statement is compressed into a single trailing clause rather than a clear leading enumeration, keeping it just below the top anchor.

Trigger Term Quality

Dozens of natural user phrasings with synonyms and troubleshooting variants are covered — "set up parsing", "regex extraction", "lookup table", "events to metrics", "spans to metrics", "E2M not producing metrics", "reduce log cost with E2M" — comprehensive coverage of how users actually ask for this.

Distinctiveness Conflict Risk

The description is Coralogix-specific and centers on a narrow, well-defined niche (parsing rules, enrichments, E2M, recording rules) with highly distinctive triggers like "E2M definition", "PromQL recording", and "labels cardinality", giving it minimal conflict risk.
