vscode-unify-chat-provider: Instructions file for Codex

AGENTS.md

vscode-unify-chat-provider AGENTS.md is an instructions file for Codex, OpenCode from smallmain/vscode-unify-chat-provider. It costs 358 tokens per session, scanned A, original, MIT.

Repository instructions for a VS Code extension that connects several language-model providers to GitHub Copilot Chat through VS Code's Language Model API. They cover strict TypeScript checks, tests, and compatibility between extension instances.

In plain words
What is it for?
Use them when adding or changing providers, VS Code commands, configuration, inline completion, communication between extension instances, or automated tests.
Why use it?
They reduce type errors and help ensure provider connections and multi-instance communication keep working across extension updates.

Instructions file for CodexOpenCode

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

This is smallmain/vscode-unify-chat-provider's own configuration. It tells Codex and OpenCode how to work on vscode-unify-chat-provider itself, so it is not a mod to install elsewhere.

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

vscode-unify-chat-provider 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

  • Prohibit code that bypasses TypeScript's strict type checking, such as as any or @ts-ignore.
  • The project should use Vitest for unit tests and @vscode/test-electron for VS Code Extension Host end-to-end tests. After the test framework is added, run npm test or npm run test:unit for pure logic changes, and run npm run test:e2e for changes involving VS Code APIs, commands, configuration wiring, or inline completion provider lifecycle.
  • Local end-to-end tests must reuse VS Code already installed on the machine. Use VSCODE_EXECUTABLE_PATH when automatic discovery is insufficient. Do not download, install, or copy VS Code for local testing, and do not modify the installed application's files or Proposed API grants. Test fallback behavior with an isolated extension identity and temporary user data. CI provisions its runtime explicitly before invoking the same installed-version-only test runner.
  • For main-instance coordination compatibility, do not use the extension/package version as the compatibility boundary. Maintain a separate main-instance compatibility version for that mechanism, and only bump it when IPC/RPC message formats, shared state contracts, or leader/follower behavior become incompatible. Compatible extension releases should continue to interoperate even when their package versions differ.
  • If you don't have a sufficient understanding of the specifications, please refer to the following official documents for more information:

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.
