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 | $0.00120 | $0.00479 |
| Opus 5.5 | $0.00048 | $0.00192 |
| Sonnet 5.5 | $0.00024 | $0.00096 |
| Haiku 4.5 | $0.00012 | $0.00048 |
Grade A, and why
wcf 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.

What it actually says
Windows Communication Foundation
Trigger On
- working on WCF services, bindings, or clients
- deciding whether a service should stay WCF or move to modern HTTP APIs
- reviewing transport, security, or interoperability settings
Workflow
- Use WCF where SOAP, WS-* features, or multi-transport service requirements are real; do not rewrite those needs into HTTP-only guidance by accident.
- Keep contracts, bindings, behaviors, and hosting configuration explicit because WCF complexity compounds through configuration indirection.
- For new REST-style services, prefer modern ASP.NET Core APIs instead of extending WCF into a shape it is no longer best suited for.
- Plan migrations per endpoint and capability: transport, security model, transaction requirements, metadata, and client compatibility.
- Validate interoperability and deployment assumptions with the actual client ecosystem, not only local service startup.
- When WCF coexists with ASP.NET, be explicit about which runtime behaviors are shared and which are not.
Deliver
- stable WCF service or client configuration
- realistic migration guidance to newer stacks where appropriate
- clear contract and binding ownership
Validate
- WCF is used for a reason the modern stack does not replace directly
- binding and security behavior are explicit
- interop is verified with real consumers
References
- migration.md - WCF to gRPC/REST/CoreWCF migration paths, decision framework, and endpoint-by-endpoint migration strategy
- patterns.md - WCF maintenance patterns for configuration, contracts, hosting, security, diagnostics, and client proxy management
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.
- 1mo ago First seen · 40 lines · 120 tokens per session scan A 5a16c7c0052e
wcf is a skill published in the GitHub repository managedcode/dotnet-skills (496 stars, last pushed yesterday), licensed MIT. It adds 120 tokens to every session and 479 once invoked, about $0.0005 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.
