devflow-planning

devflow-planning is a skill for Claude Code, Codex from KlausFreiberufler/devflow-mcp. It costs 32 tokens per session (1,247 once invoked), scanned A, original, MIT.

A set of instructions for the planning stage of a DevFlow, a workflow for proposing and approving software changes.

In plain words
What is it for?
Writing an implementation plan, listing its scope and testable outcomes, and submitting it for review without creating a separate plan file in the repository.
Why use it?
It keeps the implementation plan with the workflow and requires clear goals and acceptance criteria before approval.

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-planning 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 3d 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 — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

DevFlow — Planning State

You are in the planning state. Your job: turn the flow's description into a concrete implementation plan, then submit it for approval.

Iron Law — Plan goes to the flow, not the repo

  • Write the plan inline. Never create files like plans/foo.md, docs/PLAN.md, or any other repo-resident plan artifact.
  • Submit via flow_update({implementationPlan: <markdown>}). The backend automatically uploads it as implementation-plan.md Attachment to the flow (DF-212 mechanism, see ADR-032 Plan Schema).
  • Do not run an interactive dialogue with the user. If the flow's description is unclear, re-read it with the available context (planning_context, wiki_get_briefing, pending_work) and make explicit assumptions in the plan body. The user reviews the whole plan at approval time — that is the moment for corrections, not a turn-by-turn clarification loop.

The plan lives with the flow. Anyone can re-read it from flow_get or the UI's PlanningStateView at any time. Repo-files would diverge from flow state immediately.

Plan Template

# <Flow Title> Implementation Plan

## Goal
<one paragraph, what success looks like>

## Scope
**Files to change:**
- `path/to/file.ts` — <what changes>

## Out of scope
- <items deliberately deferred or excluded — link to follow-up flow ids where applicable>

## Implementation Steps
### Step 1 — <imperative name>
<concrete actions, including file paths and pseudo-code if helpful>

### Step 2 — <imperative name>
<...>

## Acceptance Criteria
- **AC-1:** <criterion + how to verify>
- **AC-2:** <...>

## Tasks (will be created in `in_progress`)
1. <task title> — touches: `path/to/file`
2. <...>

## Risks
- <each risk + mitigation>

## Verification
- **AC-1:** `<exact command>` → expected output
- **AC-2:** `<...>`

Adjust sections to fit the flow. Keep ACs concrete and command-verifiable.

Knowledge-Check pre-flight

Before submitting the plan to approval, run knowledge_check_flow(flowId). The response lists topics in the plan text that have no ADR / Pattern / Runbook yet. For each, call knowledge_check_resolveprefer extend over dismiss (Iron Law of the LLM-Wiki; the backend enforces this when an extend-target exists).

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-planning is a skill published in the GitHub repository KlausFreiberufler/devflow-mcp (1 stars, last pushed 5d ago), licensed MIT. It adds 32 tokens to every session and 1,247 once invoked, about $0.0002 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.
