sematext-otel

Wire a service's OpenTelemetry output to Sematext Cloud. Walks through region, App-type, instrumentation flow (managed OTLP endpoint vs Sematext Agent), and signal selection (traces/metrics/logs), then produces the exact env-var block and points at a runnable reference example in this repo. Invoke when instrumenting a new app for Sematext.

Quality

Content

85%

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

This is a strong, well-structured skill that provides highly actionable guidance for wiring OpenTelemetry to Sematext Cloud. The triage-driven workflow, concrete env-var blocks, endpoint matrices, and troubleshooting table make it immediately useful. The main weakness is moderate verbosity — some explanatory content (Sematext fundamentals, general OTel concepts) could be trimmed since Claude already understands these, and the document would benefit from being ~20% leaner.

Suggestions

Trim the 'Sematext fundamentals' section to just the non-obvious gotchas (custom X-API-TOKEN header, region-token mismatch silently drops data) — Claude already understands token-per-app patterns and auth headers.

DimensionReasoningScore

Conciseness

The skill is mostly efficient and information-dense, but includes some unnecessary explanations Claude would already know (e.g., explaining what CORS is, what auto vs manual instrumentation means in general OTel terms, and the 'Sematext fundamentals' section explaining concepts like 'one token per App' that are more user-facing than Claude-facing). The troubleshooting table and matrices are well-structured and earn their tokens, but the overall document could be tightened by ~20%.

2 / 3

Actionability

The skill provides fully executable env-var blocks for both flows, concrete agent enable commands, specific endpoint URLs with protocol variants, and clear directory paths for reference examples. The triage questions are specific and ordered, and the env-var blocks are copy-paste ready with clear placeholder conventions.

3 / 3

Workflow Clarity

The triage section provides a clear ordered sequence of questions that drives the entire workflow. The skill explicitly sequences: ask triage questions → select flow → assemble env-var block → point to reference example → verify data landing → troubleshoot if needed. Verification steps are explicit (check within 60s, specific UI locations per signal), and the troubleshooting table provides a feedback loop for error recovery.

3 / 3

Progressive Disclosure

The skill serves as a clear overview that points to per-language reference examples via well-structured relative paths, external Sematext docs, and e2e examples. References are one level deep and clearly signaled with tables mapping language/framework to directory paths. The directory structure template helps Claude navigate without needing to read every sub-README.

Description

100%

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

This is an excellent skill description that clearly articulates specific capabilities (region selection, instrumentation flow, signal selection, env-var generation), includes rich natural trigger terms from the observability domain, and provides an explicit 'Invoke when' clause. The description is concise yet comprehensive, targeting a well-defined niche that minimizes conflict risk with other skills.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: walks through region selection, App-type, instrumentation flow (managed OTLP endpoint vs Sematext Agent), signal selection (traces/metrics/logs), produces env-var blocks, and points to reference examples. Very detailed and actionable.

3 / 3

Completeness

Clearly answers both what ('Wire a service's OpenTelemetry output to Sematext Cloud' with detailed steps) and when ('Invoke when instrumenting a new app for Sematext'). The explicit trigger clause is present and specific.

3 / 3

Trigger Term Quality

Includes strong natural keywords users would say: 'OpenTelemetry', 'Sematext Cloud', 'OTLP endpoint', 'Sematext Agent', 'traces', 'metrics', 'logs', 'env-var', 'instrumenting'. Good coverage of terms a user working with observability would naturally use.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive — targets a very specific niche (OpenTelemetry + Sematext Cloud integration). The combination of vendor-specific terms (Sematext, OTLP endpoint, Sematext Agent) makes it extremely unlikely to conflict with other skills.
