neo-csharp-interface-generator

neo-csharp-interface-generator is a skill for Claude Code, Codex from Benknightdark/neo-skills. It costs 59 tokens per session (580 once invoked), scanned A, original, MIT.

A C# interface generator that extracts eligible public members from an existing class into an interface named with an I prefix.

In plain words
What is it for?
Use it to create, append, or replace a matching C# interface in a new or existing file.
Why use it?
It removes repetitive interface-writing work while enforcing rules such as getter-only properties and excluding virtual or non-public members.

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.

Security

Grade A, and why

neo-csharp-interface-generator 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.

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.

C# Interface Generator Skill Specification

Perceive

  1. Code Structure Recognition: Parse C# Class content, identify properties, methods, and access modifiers.
  2. Constraint Check:
    • Identify members with the virtual keyword.
    • Identify non-public members.
  3. Environment Awareness: When the user specifies a target file, read the file content to check for the existence of an Interface with the same name.

Reason

  1. Interface Generation Logic:
    • Naming Convention: The Interface name must be the Class name prefixed with I.
    • Property Filtering:
      • Keep only simple properties.
      • Strictly prohibit properties containing the virtual modifier.
      • Getter Only: All properties in the interface MUST only have a get; accessor. No set; or init; is allowed.
      • Include only public members.
    • Formatting: Ensure the generated Interface follows standard C# indentation and brace styles.
  2. Smart Overwrite Strategy:
    • If the target file does not exist: Plan to create a new file with necessary namespaces.
    • If the target file exists but has no Interface with the same name: Plan to append the new Interface to the end of the file.
    • If the target file exists and already contains an Interface with the same name:
      • Use regular expressions or block matching to find the start and end positions of the Interface.
      • Plan to replace only that specific block, preserving other classes, interfaces, or using declarations in the file.

Act

  1. Code Generation: Output a C# Interface that complies with the Reason logic.
  2. User Confirmation:
    • After generation, pause and ask the user: "In which file should this Interface be stored? (Please provide a relative path)".
  3. Execution Write:
    • Based on the user's response, perform read_file (if the file exists) -> logical replacement -> write_file.
    • Inform the user of the result (created, appended, or overwritten).
  4. Output Language: The final output to the user must be in Traditional Chinese (Taiwan).

neo-csharp-interface-generator is a skill published in the GitHub repository Benknightdark/neo-skills (7 stars, last pushed yesterday), licensed MIT. It adds 59 tokens to every session and 580 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 2026-08-31.
