What is refactoring-csharp?

A tool for renaming C# code symbols, such as classes, methods, or variables, across a .NET solution. It can also work across several related solutions in a monorepo, which is one repository containing multiple projects.

Use it to rename C# symbols, preview the impact of a change, and update shared code across one or more .NET solutions.

It updates references consistently, reducing the risk of missing usages during a large rename. A preview mode lets you inspect the expected changes before applying them.

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.

Any agent

npx skills add CodeAlive-AI/ai-driven-development --skill refactoring-csharp

Clone the repo

git clone --depth 1 https://github.com/CodeAlive-AI/ai-driven-development

Made for: Claude Code.

Or install ai-driven-development, the plugin that ships this one along with the rest of its 22 skills, 1 agent.

Token cost

What it costs to keep this loaded

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	$0.00060	$0.02358
Opus 5.5	$0.00024	$0.00943
Sonnet 5.5	$0.00012	$0.00472
Haiku 4.5	$0.00006	$0.00236

Security

Grade A, and why

refactoring-csharp 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 1mo ago.

The scan reads SKILL.md. This mod also ships 3 executable files (install.ps1, install.sh, release.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Refactoring C# Symbols

This skill ships a Roslyn-based C# rename CLI in src/. It is intentionally one-shot and stateless: one call resolves the target, validates the request, and returns either a preview or an applied rename. There is no public prepare step.

Canonical CLI

If the skill was installed by install.sh, prefer the prebuilt CLI:

bin/csharp-refactor rename-symbol <sln|slnx|directory> <file> <line> <oldName> <newName> [dryRun=false|true]

Otherwise run the bundled source CLI from the skill directory:

dotnet run --project src/CSharpRefactoring.Cli -- rename-symbol <sln|slnx|directory> <file> <line> <oldName> <newName> [dryRun=false|true]

When invoked from outside the skill directory, use an absolute project path:

/<skill-dir>/bin/csharp-refactor rename-symbol <sln|slnx|directory> <file> <line> <oldName> <newName> [dryRun=false|true]
# or, if no prebuilt binary is installed:
dotnet run --project /path/to/refactoring-csharp/src/CSharpRefactoring.Cli -- rename-symbol <sln|slnx|directory> <file> <line> <oldName> <newName> [dryRun=false|true]

The tool project may create normal bin/ and obj/ directories under the skill. That is expected and useful: it lets repeated runs reuse the .NET build cache instead of rebuilding the CLI from scratch.

The target solution is not redirected to a temporary build output. The CLI opens the solution from the solution directory and lets Roslyn/MSBuild use the target project's normal build cache (obj/, bin/, or the repository's configured artifacts layout). This is intentional: it avoids creating a second cache tree for the project being refactored and lets repeated renames benefit from the project's existing MSBuild/Roslyn design-time build cache.

22 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.

Changes

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.

refactoring-csharp is a skill published in the GitHub repository CodeAlive-AI/ai-driven-development (163 stars, last pushed yesterday), licensed MIT. It adds 60 tokens to every session and 2,358 once invoked, about $0.0002 per session on Opus 5.5. 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.
