generate

generate is a command for coding agents from Zulelee/test-files-mcp. It costs 36 tokens per session (235 once invoked), scanned A, original, MIT.

A command that creates a real test file from a short description, such as a JPEG, CSV, PDF, JSON file, ZIP archive, WAV file, or corrupted file.

In plain words
What is it for?
Use it to generate files with chosen sizes, row counts, dimensions, page counts, corruption, or filename edge cases, then get their saved path and metadata.
Why use it?
It saves you from manually preparing files for upload checks, parser tests, and error handling. It can also create unusual sizes, contents, and filenames that are difficult to make by hand.

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.

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

generate 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 3d 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.

What it actually says

Generate Test File

Create a test fixture using the test-files MCP server based on: $ARGUMENTS

Steps

  1. Parse the user's request from $ARGUMENTS (file type, size, count, corruption, etc.).
  2. Select the appropriate MCP tool:
    • Size-only file → create_dummy_file_tool
    • Image → create_image_tool
    • PDF → create_pdf_tool
    • CSV → create_csv_tool
    • JSON → create_json_tool
    • ZIP → create_archive_tool
    • WAV → create_audio_tool
    • Corrupted → create_corrupted_file_tool
    • Weird filename → create_edge_case_filename_tool
  3. Call the tool and confirm the file exists at the returned absolute path.
  4. Summarize: path, size, and key metadata.

If the request is ambiguous, ask one clarifying question before generating.

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.
