taskflow AGENTS.md

Project instructions for coding agents working on taskflow, a TypeScript tool that runs multi-step workflows for coding agents.

In plain words
What is it for?
Use them when developing, reviewing, or debugging taskflow and its related adapters, workflow definitions, or runtime components.
Why use it?
They give an agent the project’s structure, terminology, supported environments, and technical constraints before it changes code.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

taskflow AGENTS.md scanned grade A with 1 finding 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 yesterday.

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.

Instructions for AI coding agents working on taskflow.

Project Overview

taskflow is a declarative DAG orchestration runtime for coding agents — it runs on the Pi coding agent, on OpenAI Codex, on Claude Code, on OpenCode, and on Grok Build, and on Hermes Agent. It lets users define multi-phase workflows (fan-out, gate, loop, tournament, approval, sub-flow composition) as JSON DSL, executes them via isolated subagent processes, and returns only the final result — intermediate transcripts never enter the host context window.

Language: TypeScript (ES2022, ESM, --experimental-strip-types for direct execution in dev)
Runtime: Node.js ≥ 22.19 (uses fs.globSync, Atomics.wait)
Dependencies: Zero runtime deps. The private charterarc experiment depends only on taskflow-core. The Pi adapter (pi-taskflow) peer-depends on @earendil-works/pi-{agent-core,ai,coding-agent,tui}; the host-neutral MCP server (taskflow-mcp-core) and the four MCP host adapters (codex-taskflow, claude-taskflow, opencode-taskflow, grok-taskflow) all depend on taskflow-core (the adapters also depend on taskflow-mcp-core). Everything depends on typebox.
Layout: pnpm-workspace monorepo — taskflow-core (engine), private charterarc (project template loop), taskflow-mcp-core (MCP + DAG SVG), taskflow-hosts (codex/claude/opencode/grok runners), taskflow-dsl (S4: .tf.ts → Taskflow → FlowIR; CLI taskflow-dsl), pi-taskflow, codex-taskflow, claude-taskflow, opencode-taskflow, grok-taskflow, hermes-taskflow (host delivery packages).
Build: each package compiles to dist/*.js + .d.ts (tsc); published packages ship dist (Node refuses to type-strip .ts under node_modules). Dev resolves the TypeScript sources directly via a development export condition — no build needed to typecheck or test.

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.

taskflow AGENTS.md is an instructions file published in the GitHub repository heggria/taskflow (67 stars, last pushed 5d ago), licensed MIT. It adds 7,110 tokens to every session, about $0.0355 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
