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 | $0.00000 | $0.03270 |
| Opus 5 | $0.00000 | $0.01635 |
| Sonnet 5 | $0.00000 | $0.00654 |
| Haiku 4.5 | $0.00000 | $0.00327 |
Grade A, and why
AspectGenerator 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 434 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AspectGenerator Agent Skill
Use this file as the compact agent-oriented guide for using and reviewing AspectGenerator in consuming projects.
AspectGenerator provides AOP-like compile-time method aspects for C# by rewriting visible call sites with C# interceptors. It is not runtime AOP, does not use runtime proxies, and does not weave IL.
Build-tool requirement
AspectGenerator requires projects that use it to be built with the .NET 10 SDK/compiler.
This is a build-toolchain requirement, not necessarily the same thing as the project target framework requirement. The important part is the SDK/compiler used by dotnet build, MSBuild, or Visual Studio. AspectGenerator itself targets netstandard2.0; consuming projects need the .NET 10 compiler because the generator uses the stable Roslyn interceptor API based on opaque InterceptableLocation data.
Do not describe this as simply "requires .NET 10". Say "requires the .NET 10 SDK/compiler to build".
The legacy preview API InterceptsLocation(filePath, line, character) is not supported.
Package reference rule
AspectGenerator runs in the compilation that references the NuGet package.
Every project whose call sites should be intercepted must reference AspectGenerator directly. A shared aspect library may define aspect attributes and hooks, but applications or libraries containing the actual call sites must also reference AspectGenerator directly.
Use this rule when reviewing multi-project solutions:
aspect definitions live in one project
call sites live in another project
=> both projects usually need direct AspectGenerator package references
The package imports the required MSBuild wiring automatically for direct package consumers.
Generated API ownership
AspectGenerator can generate the authoring/runtime API into the current compilation:
AspectAttribute
AspectInstanceLifetime
InterceptInfo
InterceptInfo<T>
InterceptData<T>
InterceptType
InterceptResult
Void
AspectGeneratorOptionsAttribute
AspectDiagnosticSeverity
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.

AspectGenerator is a skill published in the GitHub repository igor-tkachev/AspectGenerator (11 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,270 tokens. 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.
