test-add

test-add is a skill for Claude Code from DanialDaeHyunNam/omniscitus. It costs 51 tokens per session (1,032 once invoked), scanned A, original, MIT.

A test-scaffold generator that reads a source file and creates a matching test file plus structured test definitions. It supports several common programming languages and their usual test tools.

In plain words
What is it for?
Use it with a file path when adding tests. It identifies the language, examines the file's functions and dependencies, and creates tests under .omniscitus/tests/.
Why use it?
Writing the initial test structure for every file takes time and can miss edge cases, errors, or side effects.

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

test-add 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Test-Add — Universal Test Scaffold

Create a structured test definition (meta.yaml) and test file for any source file.

When to Use

  • User types /test-add {file-path}
  • User says "add tests for {file}", "테스트 추가"

Instructions

Step 1: Validate Target

Read the file at the given path. If it doesn't exist, report and stop.

Detect the programming language from the file extension:

  • .ts, .tsx → TypeScript (framework: vitest)
  • .js, .jsx → JavaScript (framework: vitest)
  • .py → Python (framework: pytest)
  • .go → Go (framework: go test)
  • .rs → Rust (framework: cargo test)
  • .rb → Ruby (framework: rspec)
  • Other → ask user which framework to use

Step 2: Analyze the File

Read the source file. Identify:

  • Exported functions, classes, methods
  • Input parameters and return types
  • Edge cases (null handling, error paths, boundary values)
  • Dependencies and side effects (DB, API, filesystem)

Step 3: Create Test Directory

Mirror the source path under .omniscitus/tests/:

mkdir -p .omniscitus/tests/{path-to-source-dir}

Example: src/lib/auth.ts.omniscitus/tests/src/lib/auth/

Step 4: Generate meta.yaml

Create .omniscitus/tests/{path}/meta.yaml.

CRITICAL: Each suite MUST include a signature block with typed params and returns. This enables type-safe test case creation in the Birdview UI.

target: {relative-path-to-source}
language: {detected-language}
framework: {detected-framework}
last_updated: {YYYY-MM-DD}

suites:
  - name: {function-or-class-name}
    type: unittest               # unittest | integration | e2e
    signature:
      params:
        - name: {param-name}
          type: string           # string | number | boolean | object | array
        - name: {param-name}
          type: object
          optional: true         # mark optional params
          properties:
            {prop}: {type}       # nested object shape
      returns:
        type: object             # return type
        properties:
          {prop}: {type}         # return shape for objects
    cases:
      - title: "{descriptive test name}"
        description: "{what this test verifies}"
        input:
          {param}: {value}
        expected:
          strategy: exact          # exact | contains | schema | regex
          value: {expected-output}

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.

test-add is a skill published in the GitHub repository DanialDaeHyunNam/omniscitus (5 stars, last pushed 1mo ago), licensed MIT. It adds 51 tokens to every session and 1,032 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 2026-08-31.
