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.

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 | $0.00081 | $0.05318 |
| Opus 5 | $0.00041 | $0.02659 |
| Sonnet 5 | $0.00016 | $0.01064 |
| Haiku 4.5 | $0.00008 | $0.00532 |
Grade A, and why
agents-sdk-python-otel 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 714 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenTelemetry for Agents SDK (Python)
Goal
Configure traces, metrics, and logs for a Python Agents SDK application, including the SDK's built-in telemetry and a local Aspire Dashboard. Preserve the project's dependency manager, web host, logging design, and startup lifecycle.
Non-negotiable rules
- Configure global OpenTelemetry providers before importing most
microsoft_agentsSDK modules. The Python SDK resolves tracers and meters at import time.microsoft_agents.activitycontains no telemetry and is safe to import before provider setup. - Extend existing providers instead of attempting to replace already-set global providers. OpenTelemetry Python does not permit provider replacement after initialization.
- Instrument aiohttp, requests, or other libraries after providers are configured and before the application starts handling traffic.
- Use one stable application-specific
service.name. - Let exporters read standard OTEL environment variables. Never hardcode collector credentials, API keys, or connection strings.
- Never add prompts, responses, message text, tokens, authorization headers, cookies, secrets, attachment contents, user names, user IDs, conversation IDs, activity IDs, or arbitrary HTTP headers to custom telemetry by default.
- Keep custom metric attributes low-cardinality. Good dimensions include route type, activity type, channel ID, operation, status, and error type.
- Use batch processors for normal applications. Simple processors are only appropriate for narrow debugging or tests.
- Do not set always-on sampling as a production default. Honor the deployment sampling policy or configure a deliberate parent-based ratio.
- Flush tracer, meter, and logger providers during graceful shutdown. Do not silently ignore exporter or shutdown failures.
- Avoid duplicate
LoggingHandlerinstances on the root logger. - Aspire Dashboard anonymous mode is local-development only. Bind it to loopback and never deploy that configuration.
- Telemetry must record and re-raise application exceptions.
What ships with it
2 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.

agents-sdk-python-otel is a skill published in the GitHub repository microsoft/Agents (1,050 stars, last pushed 4d ago), licensed MIT. It adds 81 tokens to every session and 5,318 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.
