tabame: Instructions file for Codex

AGENTS.md

tabame AGENTS.md is an instructions file for Codex, OpenCode from Far-Se/tabame. It costs 229 tokens per session, scanned A, original, MIT.

Project instructions for validating Dart code and adding native Windows features. Dart is the programming language used by the project, while native features use operating-system-specific code.

In plain words
What is it for?
Use them when editing Dart files or implementing a feature that needs Windows APIs. They specify which formatting and analysis commands to run and what to report if they fail.
Why use it?
They make the required checks and platform limits clear, so developers do not run forbidden commands or validate more of the project than necessary.

Instructions file for CodexOpenCode

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

This is Far-Se/tabame's own configuration. It tells Codex and OpenCode how to work on tabame 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 tabame 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

tabame 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

Dart validation

After editing Dart files, from the project root, using dart as resolved from PATH:

dart format <changed-files>
dart analyze <changed-files>

Never: invoke dart.bat/flutter.bat (even via absolute path), invoke Dart by absolute path, modify/reconstruct PATH, use the Dart MCP dart_format tool, or run flutter build/flutter run. Never run any building commands like flutter build windows if you havent changed CPP/H code. Never run flutter test or any form of tests. If you modified some code that has a _test.dart file, only run that.

Rules: one Dart command at a time; format/analyze only files changed this task; run format once and analyze once (no full-project analysis unless asked); on failure, report the command, the failure, and any output as-is.

Native Feature Implementation

Only implement code for Windows if you need native API/functions and leave a mockup for Linux and Mac with comment //TODO: Implement multiplatform

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.
