Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00080 | $0.01020 |
| Opus 5 | $0.00040 | $0.00510 |
| Sonnet 5 | $0.00016 | $0.00204 |
| Haiku 4.5 | $0.00008 | $0.00102 |
Grade A, and why
otel-semantic-conventions scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

OpenTelemetry Semantic Conventions
This skill governs correct selection, placement, and validation of telemetry attributes and metric instruments according to the OpenTelemetry Semantic Conventions specification. For span naming, span kinds, and span status codes, see the otel-instrumentation skill.
The Attribute Registry is the single source of truth for all defined attributes.
Rules
| Rule | Description | Use Case |
|---|---|---|
| attributes | Attribute registry, selection, placement, common attributes by domain | Choosing or reviewing attributes; HTTP/DB/messaging/RPC attributes; attribute placement (resource vs span) |
| versioning | Semconv versioning, stability, migration | Semconv version migration |
| dash0 | Dash0 derived attributes and feature dependencies | Dash0 derived attributes |

How to select the right attribute
- Search the registry first — Look up the concept in the Attribute Registry. Use the standard name if it exists (e.g., prefer
http.request.methodover a customcustom.http.verb). Custom names fragment querying and break tooling — only create a custom attribute when no registry entry covers the concept. - Check stability — Prefer
stableattributes; note anyexperimentalattributes that may change. See versioning. - Place at the correct level — Resource attributes describe the entity producing telemetry; span/log attributes describe the individual operation. Do not duplicate across levels. Once an attribute is at a given level, keep it there consistently across all services.
- Verify cardinality — Metric attribute values must be low-cardinality (bounded set). Variable data (user IDs, request paths with parameters) belongs in span attributes, not metric attributes.
- Custom attribute as last resort — Only create a custom attribute if no registry entry covers the concept. Document the decision and follow the
org.namespace.attribute_namenaming pattern.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

otel-semantic-conventions is a skill published in the GitHub repository dash0hq/agent-skills (89 stars, last pushed 11d ago), licensed Apache-2.0. It adds 80 tokens to every session and 1,020 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
