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.

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 | $0.00035 | $0.00371 |
| Opus 5 | $0.00017 | $0.00186 |
| Sonnet 5 | $0.00007 | $0.00074 |
| Haiku 4.5 | $0.00003 | $0.00037 |
Grade A, and why
otel-sdk-versions 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.
What it actually says
OpenTelemetry SDK Versions
Use this skill when you need the latest released OpenTelemetry SDK or package version for a language.
Workflow
- Open
references/generated/otel-version-index.md.
- identify the row for the project language and package
- use the bundled table as the default source of truth for supported languages in this repository
- Choose the version deliberately.
- prefer the latest released version when it is compatible with the project
- if the latest release is not compatible, choose the latest compatible version and state the compatibility reason explicitly
- reuse that decision for the rest of the task unless the language, package, or constraints change
- Resolve companion packages from the release source.
- the index covers one primary SDK package per language
- if the task requires additional packages from the same ecosystem (exporters, instrumentations, resource detectors), look up their versions from the release source — do not infer or reuse the primary package version
- sub-packages within the same project often share a version line but not always; confirm each package individually
- Use the linked follow-up sources when needed.
- use the Release Source column to confirm the package or repo
- use the Setup Docs column for SDK setup guidance
- use the Examples column for implementation references when examples are available
- Handle gaps explicitly.
- if the requested language or package is not in the bundled index, say that the index does not cover that exact package
- then fall back to the official release source and official docs for that package
- do not assume an unreleased, prerelease, or incompatible version is acceptable without saying so
What ships with it
1 file 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-sdk-versions is a skill published in the GitHub repository ollygarden/opentelemetry-agent-skills (98 stars, last pushed yesterday), licensed Apache-2.0. It adds 35 tokens to every session and 371 once invoked, about $0.0002 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.
