In plain words

Why use it?
They give a coding agent the project context and validation commands needed to make changes that fit the existing architecture.

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

This is bramses/chatgpt-md's own configuration. It tells Codex and OpenCode how to work on chatgpt-md 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 chatgpt-md configures →

About the project

ChatGPT MD is an Obsidian plugin that lets users chat with AI inside their notes, reference notes through wiki links, and optionally let the AI search the vault, read notes, or browse the web with approval. It is for writers and developers who want cloud or locally hosted AI assistance while keeping their work in an Obsidian vault. The catalogue entries provide instructions for using the plugin.

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

chatgpt-md 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 2mo 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.

AGENTS.md

AI coding-agent instructions for chatgpt-md.

Project overview

chatgpt-md is an Obsidian community plugin that brings LLM workflows into markdown notes. It supports:

  • Chat interactions directly inside Obsidian notes.
  • Multiple providers: OpenAI, OpenRouter, Anthropic, Gemini, Ollama, LM Studio, Z.AI, and compatible APIs.
  • Per-note configuration through YAML frontmatter.
  • Streaming responses.
  • Human-approved AI tool calls for vault and web search workflows.

The plugin is TypeScript, bundled by esbuild, and runs inside the Obsidian plugin runtime.

Validation commands

Use npm for validation unless the project explicitly changes package-manager policy.

npm run build
npm test -- --runInBand
npm run lint

Lint runs the official Obsidian plugin rules via eslint-plugin-obsidianmd. Expected state: 0 errors and a small set of known warnings (untyped tool results in ToolService, the prefer-setting-definitions nudge). Do not add new warnings; do not treat the known ones as task blockers. no-unsupported-api cannot be disabled inline — it validates every API call against minAppVersion in manifest.json.

Compatibility floor and dependency pins

  • minAppVersion is 1.11.4, pinned by the SecretStorage/SecretComponent credential APIs (ApiAuthService). Copilot uses the same floor.
  • The obsidian devDependency is pinned to the same 1.11.4 so tsc enforces the floor alongside the lint rule. Never set it back to latest.
  • @codemirror/state (6.5.0) and @codemirror/view (6.38.6) must stay exact: obsidian declares them as exact peers.
  • typescript is 6.x latest (<6.1.0): TypeScript 7 is blocked by @typescript-eslint peer ranges.
  • When raising minAppVersion, update the obsidian typings pin in the same change.

Releasing

  1. Merge work to master, validate (npm test -- --runInBand, npm run build).
  2. node update-version.mjs <x.y.z> — updates package.json, manifest.json, versions.json, commits, and tags.
  3. Push master and the tag.
  4. Create the GitHub release with the three Obsidian-required assets: main.js, manifest.json, styles.css. versions.json gates updates so users on older Obsidian stay on the last compatible release.

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.
