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 | $0.00109 | $0.02873 |
| Opus 5.5 | $0.00044 | $0.01149 |
| Sonnet 5.5 | $0.00022 | $0.00575 |
| Haiku 4.5 | $0.00011 | $0.00287 |
Grade A, and why
worker-services 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 1mo 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.

.NET Worker Services
Trigger On
- building long-running background services or scheduled workers
- adding hosted services to an app or extracting them into a worker process
- reviewing graceful shutdown, cancellation, queue processing, or health behavior
Documentation
- Worker Services in .NET
- Background tasks with hosted services in ASP.NET Core
- Create Windows Service using BackgroundService
- App health checks in .NET
- Health checks in ASP.NET Core
References
- patterns.md - BackgroundService patterns, graceful shutdown, and health check implementations
- anti-patterns.md - Common worker service mistakes and how to avoid them
Workflow
-
Use BackgroundService as your base class:
- Provides standard
StartAsync/StopAsynchandling - Focus on implementing
ExecuteAsynconly - Proper cancellation token management built-in
- Provides standard
-
Handle scoped dependencies correctly:
- Create service scopes for scoped services
- No scope is created by default in hosted services
-
Implement graceful shutdown:
- Propagate cancellation tokens throughout
- Complete work promptly when token fires
- Avoid ungraceful shutdown at timeout
-
Keep execution loop thin:
- Move business logic to testable services
- Handle exceptions to prevent service crashes
- Use
PeriodicTimerfor scheduled work
-
Add observability:
- Use health checks for readiness/liveness
- Expose metrics and structured logging
- Consider distributed locks for multi-instance
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.

worker-services is a skill published in the GitHub repository managedcode/dotnet-skills (488 stars, last pushed yesterday), licensed MIT. It adds 109 tokens to every session and 2,873 once invoked, about $0.0004 per session on Opus 5.5. 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.
