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 | $0.00049 | $0.00903 |
| Opus 5.5 | $0.00020 | $0.00361 |
| Sonnet 5.5 | $0.00010 | $0.00181 |
| Haiku 4.5 | $0.00005 | $0.00090 |
Grade A, and why
csharpier 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 19d 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
98% identical to csharpier — 8 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.

CSharpier for .NET
Trigger On
- the repo uses or wants
CSharpier - the team prefers an opinionated formatter over many configurable style knobs
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
- repos that already standardized on
dotnet formatas the only formatter
Inputs
- the nearest
AGENTS.md - current formatting ownership model
- any
.csharpierignoreor.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
- Decide whether CSharpier is the primary formatter or only complements other tools.
- Use
checkmode in CI. - Keep ignore files and config explicit in repo.
- Do not let
CSharpieranddotnet formatboth own the same formatting space without documentation.
Bootstrap When Missing
If CSharpier is not configured yet:
- Detect current state:
rg --files -g '.config/dotnet-tools.json' -g '.csharpierignore'dotnet tool list --localdotnet tool list --global
- Prefer local tool installation for reproducible CI:
dotnet new tool-manifest(if missing)dotnet tool install csharpier
- Add
.csharpierignorewhen needed and define ownership vsdotnet formatinAGENTS.md. - Add
dotnet csharpier check .to CI. - Run
dotnet csharpier check .and returnstatus: configuredorstatus: improved. - If the repo intentionally uses only
dotnet format, returnstatus: not_applicableunless migration is requested.
Deliver
- explicit CSharpier ownership and commands
- CI-safe formatter checks
Validate
- formatter ownership is not ambiguous
- the repo is comfortable with opinionated formatting decisions
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.

csharpier is a skill published in the GitHub repository managedcode/Orleans.RateLimiting (30 stars, last pushed 11d ago), licensed MIT. It adds 49 tokens to every session and 903 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 98% identical to csharpier, differing in 8 lines, and is treated as a copy.
