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 | $0.00061 | $0.00333 |
| Opus 5 | $0.00030 | $0.00167 |
| Sonnet 5 | $0.00012 | $0.00067 |
| Haiku 4.5 | $0.00006 | $0.00033 |
Grade A, and why
dotnet 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.
What it actually says
.NET Application Development
Workflow
- Identify whether the change belongs in an app surface, service, manager, MCP tool, DTO/model, CodeGenerator, or Share.
- Read the calling surface from CLI or Blazor before changing shared behavior.
- Check shared entities and
DefaultDbContextbefore changing persistence. - Preserve dependency direction: app projects depend on CoreMod; CoreMod depends on CodeGenerator and Share; Share stays foundational.
Conventions
- Put cross-step workflows and external I/O in services.
- Put MiniDb query/update behavior in managers.
- Keep app-facing service methods stable when both CLI and Blazor consume them.
- Use existing DTO patterns and Mapster helpers (
MapTo,Merge,Adapt) where nearby code does. - Pass
CancellationTokenthrough file, HTTP, and long-running async operations. - Make HTTP services testable with injectable clients or handlers.
- Log exceptions with structured logging before wrapping them in localized, user-friendly errors.
- Keep MCP tools as protocol surfaces: stable parameter names, returned shapes, and no console output.
Tests
- Add tests under
tests/StudioMod.Tests/Services,Managers, orCommandsdepending on the observable behavior. - Stub HTTP and isolate filesystem/MiniDb state.
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.

dotnet is a skill published in the GitHub repository AterDev/Perigon.CLI (53 stars, last pushed 3d ago), licensed Apache-2.0. It adds 61 tokens to every session and 333 once invoked, about $0.0003 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.
