ma-plan

ma-plan is a skill for Claude Code from JeonJe/claude-plugins. It costs 125 tokens per session (1,268 once invoked), scanned A, original, MIT.

A planning tool for MA work that turns an approved product requirements document and design into one implementation plan for each target project. It reads each repository's rules, similar code, and testing patterns before producing and checking the plans.

In plain words
What is it for?
Use it when you have an MA issue and need validated implementation plans for one or more repositories. It is not intended for ordinary planning or code changes.
Why use it?
It helps turn a product request into concrete, project-specific work while exposing missing decisions or unclear requirements before coding begins.

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

ma-plan 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 7d 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/ma-plan

Generate one executable implementation PLAN per target project. Keep product code read-only; this skill writes only temporary PLAN files for later review and handoff. Each PLAN also decides whether the runtime E2E gate is required, so later phases do not invent verification scope after implementation.

Invocation

/ma-plan <issue-key> [--projects=project-a,project-b] [--auto]
Input Action Output
/ma-plan PROJ-123 Derive projects, confirm, dispatch Plan Agents One PLAN per project
/ma-plan PROJ-123 --projects=example-frontend,example-backend Use the explicit registered projects Two validated PLAN files
/ma-plan PROJ-123 --auto Skip confirmation only when inputs and targets are unambiguous Validated PLANs or [BLOCKED] evidence

Preconditions

  1. Read the ma skill's scope gate (../ma/references/scope-gate.md) and retain a terminal scope of plan. Do not enter handoff or implementation.
  2. Require PRD, design, and diagrams at their canonical {contextRoot}/{domain}/ paths.
  3. Scan PRD/design open-decision sections. If an unresolved [Blocking] product or contract decision remains, return [BLOCKED]; Important/Deferrable items may continue as PLAN risks.
  4. Resolve projects from explicit --projects, otherwise from the PRD affected-project list and design Cross-repo Impact rows marked Yes.
  5. Validate every project against the workspace config projects registry. If PRD and design disagree, ask for reconciliation; --auto does not guess the project set.
  6. If a target PLAN already exists, update it as a resume only when its key/project identity matches. Do not create duplicate variants or silently overwrite a different target.

Adaptive planning

Resolve Small, Medium, or Large from the design and affected surface. Apply the evidence budgets in config/inputs.md and step ranges in templates/plan.md; treat them as targets rather than quotas and never add filler.

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.
