# OpenTelemetry Semantic Conventions

Use this skill when you need released semantic convention guidance for naming, attributes, or compliance checks.


## Workflow

1. Start with released semantic conventions, not model memory.
- do not load the full semantic convention spec into context
- use the bundled lookup script to query only the needed released group or attribute

2. Choose the closest released group before inventing custom keys.
- identify the boundary type such as `http`, `db`, `messaging`, `rpc`, or `network`
- pick one primary group first, then add related groups only when they add needed context
- see `references/semconv-selection.md`

3. Query only the released guidance you need.
- list groups: `./scripts/query-otel-semantic-conventions.sh --groups`
- inspect one group: `./scripts/query-otel-semantic-conventions.sh http`
- inspect one kind: `./scripts/query-otel-semantic-conventions.sh http spans`
- inspect one exact attribute or entry: `./scripts/query-otel-semantic-conventions.sh http http.request.method`
- see `references/otel-semantic-conventions.md`

4. Apply the released naming and attribute rules directly.
- use required and recommended attributes before optional ones
- derive semconv-governed span names directly from the released naming rule
- do not prepend or append protocol labels, hostnames, product names, business hints, or other custom prose to semconv-governed span names
- if the released naming rule does not provide a low-cardinality target, use the simpler fallback allowed by that convention
- if no released key exists, use a stable custom namespace and keep values bounded

5. Return the result with exact source context.
- include the group name, released version, and source URL from the script output
- call out any concrete compatibility limitation if the implementation cannot fully match the released guidance
