devflow

A set of rules for DevFlow, a structured process for planning, approving, implementing, reviewing, and finishing code changes. It requires an active workflow before edits can be made.

In plain words
What is it for?
Use it to start or join a DevFlow session, submit an implementation plan, follow the required workflow states, apply TDD to behavior changes, and extend existing documentation when appropriate.
Why use it?
It prevents unplanned code changes and makes each change pass through planning, testing, review, and documentation checks. TDD means writing a failing test, making it pass, and then improving the 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

devflow 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.

What it actually says

DevFlow

This project uses DevFlow for structured AI development workflows.

Quick Start

  1. devflow_status() → check connection (browser opens for first auth)
  2. flow_list() → find a free flow, OR flow_create({summary}) to start one
  3. devflow_init({flowId}) → begin your session — without this, edits are blocked
  4. Follow allowedActions and nextStep from each tool response

Flow States

idea → planning → approval → ready → in_progress → review → done

Review states wait for user-approval in the DevFlow UI.

Iron Laws

  • No code changes without active flow. Hooks block apply_patch / edit / write until .devflow-active exists.
  • Plan first, code second. Submit implementation_plan via flow_update({currentState: "approval"}) before implementing.
  • TDD for changes that introduce behavior. Failing test → green → refactor.
  • Knowledge-extend > create > defer > NEVER dismiss. When the wiki has a relevant ADR/pattern, extend it instead of creating a new one.
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.

devflow is a cursor rule published in the GitHub repository KlausFreiberufler/devflow-mcp (1 stars, last pushed 3d ago), licensed MIT. It adds 285 tokens to every session, about $0.0014 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 2026-08-31.
