agtx is a terminal-based shared workspace where multiple coding agents coordinate through a task board. Developers use it to delegate work, run agents in parallel across git worktrees, and move tasks through different workflow phases.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00580 | $0.00580 |
| Opus 5 | $0.00290 | $0.00290 |
| Sonnet 5 | $0.00116 | $0.00116 |
| Haiku 4.5 | $0.00058 | $0.00058 |
Grade A, and why
agtx 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This file provides guidance to AI coding agents (Claude Code, Codex, Gemini, Copilot, OpenCode, Cursor, etc.) when working with the agtx codebase.
What is agtx?
A terminal-native kanban board for managing multiple coding agent sessions in parallel. Each task gets its own git worktree, tmux window, and agent session. Written in Rust.

Core Concepts
- Tasks move through:
Backlog → Planning → Running → Review → Done - Each task gets a git worktree + tmux window + agent session
- Plugins (TOML) customize the task lifecycle per phase
- MCP server (
agtx mcp-serve) exposes the board as tools over stdio - Global MCP (
agtx mcp-serve, no args) serves all projects via~/.config/agtx/index.db - Project MCP (
agtx mcp-serve <path>) serves a single project (used by the orchestrator)

Rules
- Edit
src/for behavior changes — never edit generated or compiled artifacts - Run
cargo test --features test-mocksbefore considering any change done - Database migrations use
ALTER TABLE ... ADD COLUMN(errors ignored if column exists) - Mock-dependent tests use
#[cfg(feature = "test-mocks")] - See CLAUDE.md for adding new fields, agents, plugins, shortcuts
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.

agtx AGENTS.md is an instructions file published in the GitHub repository fynnfluegge/agtx (1,494 stars, last pushed yesterday), licensed Apache-2.0. It adds 580 tokens to every session, about $0.0029 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
