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 | $0.00055 | $0.00962 |
| Opus 5 | $0.00028 | $0.00481 |
| Sonnet 5 | $0.00011 | $0.00192 |
| Haiku 4.5 | $0.00006 | $0.00096 |
Grade A, and why
dotnet-format 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.

dotnet format
Trigger On
- the repo uses
dotnet format - you need a CI-safe formatting check for .NET
- the repo wants
.editorconfig-driven style enforcement
Value
- produce a concrete project delta: code, docs, config, tests, CI, or review artifact
- reduce ambiguity through explicit planning, verification, and final validation skills
- leave reusable project context so future tasks are faster and safer
Do Not Use For
- repositories that intentionally use
CSharpieras the only formatter - analyzer strategy with no formatting command change
Inputs
- the nearest
AGENTS.md - the solution or project path
- the current
.editorconfig
Quick Start
- Read the nearest
AGENTS.mdand confirm scope and constraints. - Run this skill's
Workflowthrough theRalph Loopuntil outcomes are acceptable. - Return the
Required Result Formatwith concrete artifacts and verification evidence.
Workflow
- Prefer the SDK-provided
dotnet formatcommand instead of inventing custom format scripts. - Start with verify mode in CI:
dotnet format TARGET --verify-no-changes. - Use narrower subcommands only when the repo needs them:
whitespacestyleanalyzers
- Keep
.editorconfigas the source of truth for style preferences. - If the repo also uses
CSharpier, document which tool owns which file types or rules.
Bootstrap When Missing
If dotnet format is requested but not available yet:
- Detect current state:
dotnet --infodotnet format --version
- Treat
dotnet formatas SDK-provided, not as a separate repo-local tool by default. - If the command is missing, install or upgrade to a supported .NET SDK, then recheck
dotnet format --version. - Add explicit local and CI commands to
AGENTS.md, usually:dotnet format TARGET --verify-no-changes
- Run the chosen command once and return
status: configuredorstatus: improved. - If the repo intentionally uses only
CSharpierfor formatting ownership, returnstatus: not_applicable.
What ships with it
4 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.

dotnet-format is a skill published in the GitHub repository managedcode/PrompterOne (42 stars, last pushed 3mo ago), licensed MIT. It adds 55 tokens to every session and 962 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.
