AGENTS.md

graphics-mcp AGENTS.md is an instructions file for Codex, OpenCode from lesleslie/graphics-mcp. It costs 406 tokens per session, scanned A, original, BSD-3-Clause.

Repository-specific instructions for developing and testing the graphics-mcp Python package, including its structure, commands, and coding standards.

In plain words
What is it for?
Use them when editing graphics_mcp, writing tests, running pytest, checking Ruff linting and formatting, or maintaining the project’s documentation and build output.
Why use it?
They help an agent work within the repository’s existing organization and verify changes with the project’s documented tools.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md.

This is lesleslie/graphics-mcp's own configuration. It tells Codex and OpenCode how to work on graphics-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything graphics-mcp configures →

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

graphics-mcp AGENTS.md 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.

What it actually says

Repository Guidelines

Project Structure & Module Organization

  • graphics_mcp/ contains the server package, including backend integrations, tool implementations, and image-processing helpers.
  • settings/ stores configuration defaults, and tests/ should mirror the package structure for backend and tool coverage.
  • README.md and CLAUDE.md should remain the primary operator-facing documentation; avoid hiding important behavior in ad hoc scripts.
  • Generated artifacts in dist/ should be treated as build output.

Build, Test, and Development Commands

  • uv sync --group dev installs development dependencies.
  • Use the repo's documented local serve commands for stdio or HTTP smoke tests.
  • uv run pytest executes the test suite.
  • uv run ruff check graphics_mcp tests and uv run ruff format graphics_mcp tests cover linting and formatting.

Coding Style & Naming Conventions

  • Use explicit typing, validate file inputs, and keep tool handlers thin.
  • Prefer backend-specific helpers beneath the package rather than packing logic into server entrypoints.
  • Keep module names snake_case and user-facing tool responses structured and predictable.

Testing Guidelines

  • Add coverage for image transformations, path validation, and failure modes.
  • Prefer fixture-based image assets and deterministic outputs where possible.

Commit & Pull Request Guidelines

  • Use focused commits such as fix(convert): preserve alpha channel on resize.
  • PRs should mention backend impact, validation commands, and any output differences.

Security & Configuration Tips

  • Validate file paths and format conversions carefully.
  • Never trust user-supplied paths or unchecked image metadata.

Built on Oneiric for runtime configuration and mcp-common for the FastMCP baseline. Crackerjack gates every commit.

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.
