planflow

planflow is a skill for Claude Code, Codex from davejj1530/planflow-greenlight. It costs 53 tokens per session (1,052 once invoked), scanned A, original, MIT.

A planning workflow that creates an editable browser-based flowchart and requires approval before coding work begins. It is designed for reviewing a task plan before files are changed.

In plain words
What is it for?
Use it to investigate a task, create three to nine concrete steps with details, edit their order or structure in a browser, and approve the plan before changes are made.
Why use it?
Plans can contain missing, unnecessary, or wrongly ordered steps. This provides a review point where you can change the plan before execution.

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

planflow 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 6d 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 — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are running the PlanFlow workflow for the task the user gives you.

Follow this workflow exactly. Do not skip the approval step and do not use your own built-in plan mode or planning tools; PlanFlow replaces them.

1. Investigate

Read whatever code, configs, or docs you need to plan this task well. Do not modify any file and do not run any state-changing command yet.

2. Draft the plan

Break the task into 3 to 9 concrete steps. Each step needs:

  • title: a short imperative phrase (under 60 characters), e.g. "Add rate-limit middleware".
  • detail: 1 to 3 sentences saying exactly what will change, in which files, and why.
  • id: a stable id (s1, s2, ...) so other steps can reference it.

Three optional fields express structure. Use them only when the plan genuinely has it; a simple sequence needs none of them:

  • after: array of step ids that must complete first. Use for real branches, joins, or order-independent steps. A step without after follows the previous step.
  • condition: short label for when a step runs, e.g. "cache hit" or "tests fail". It renders on the step's incoming edge. Treat it as binding during execution: only run the step when its condition holds.
  • feature: workstream name when one plan spans distinct features. Steps sharing a feature are enclosed together on the canvas.

Worked example, a conditional fork inside one feature:

{ "id": "s2", "title": "Add cache lookup", "feature": "Caching", "after": ["s1"] }
{ "id": "s3", "title": "Serve cached response", "feature": "Caching", "after": ["s2"], "condition": "cache hit" }
{ "id": "s4", "title": "Fetch upstream and store", "feature": "Caching", "after": ["s2"], "condition": "cache miss" }

Steps must be ordered so that each one can be executed after its dependencies. Also write a one-paragraph summary of the overall approach and any tradeoffs.

3. Request approval in the browser

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
