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 5.1 | $0.00109 | $0.02488 |
| Opus 5.5 | $0.00044 | $0.00995 |
| Sonnet 5.5 | $0.00022 | $0.00498 |
| Haiku 4.5 | $0.00011 | $0.00249 |
Grade A, and why
process-api-net11 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 3d 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.
This is a copy
100% identical to process-api-net11 — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Process API Improvements — .NET 11
New APIs added to System.Diagnostics.Process in .NET 11 simplify process management, eliminate boilerplate, and prevent common deadlock patterns when capturing output in .NET 11 or later applications.
When to Use
- Running or orchestrating external processes in a .NET 11 (or later) project.
- Needing to start a process, wait for it to exit, and capture its output/error streams without risking deadlocks (
Process.RunAndCaptureText[Async]). - Wanting to ensure child processes are automatically terminated when the parent process exits (
KillOnParentExit). - Requiring lightweight, low-overhead process creation via
SafeProcessHandleon supported platforms. - Requiring fine-grained control over handle inheritance (
InheritedHandles) or starting detached processes (StartDetached).
When Not to Use
- The project targets .NET 10 or earlier — these APIs are not available before .NET 11.
- The default
Process.Start()is sufficient and does not require output capturing or advanced lifecycle rules.
Target Framework

New APIs
Types
Before using the new convenience methods, note the following types. Use the framework types directly:
| Type | Kind | Read-only properties |
|---|---|---|
ProcessExitStatus |
Sealed class | int ExitCode, bool Canceled, PosixSignal? Signal |
ProcessTextOutput |
Sealed class | ProcessExitStatus ExitStatus, string StandardOutput, string StandardError, int ProcessId |
ProcessOutputLine |
Readonly struct | string Content, bool StandardError |
ProcessExitStatus describes the outcome of a completed process. Interpret ExitCode using the external command's contract; there is no universal Success property. ProcessTextOutput contains the exit status, captured output and error text, and process ID. ProcessOutputLine identifies one output line and whether it came from standard error.
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.

process-api-net11 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 2,488 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to process-api-net11, differing in 0 lines, and is treated as a copy.
