taskflow

A workflow tool for coordinating several coding-agent tasks as a planned sequence or graph. It can split work into parallel tasks, apply checks and approvals, repeat steps, and resume runs.

In plain words
What is it for?
Use it to define and run coding workflows in JSON, inspect their status and history, and pause, resume, cancel, or review runs.
Why use it?
It helps organize multi-step agent work without manually tracking every task or filling your conversation with intermediate transcripts. It can also check a workflow before running it.

Grade A, and why

taskflow 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 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.

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.

Taskflow lets you define multi-phase subagent workflows (fan-out, gates, loops, tournaments, approvals, sub-flow composition) as JSON, verify them before they run, and keep intermediate transcripts out of your context — exposed to Codex, Claude Code, and OpenCode as the taskflow_* MCP tools plus a routing skill."

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.
