A command that creates an evidence-based implementation plan for an active milestone, a defined piece of project work. It breaks the work into small tasks with files, tests, scope boundaries, and checkable acceptance conditions.

Use it to plan milestone work, research the relevant code, create board tasks, and coordinate independent areas of work.

It turns a broad objective into traceable work items and records them in both a plan file and a task board.

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.

Clone the repo

git clone --depth 1 https://github.com/benrben/MPGA

Made for: Claude Code.

Or install mpga, the plugin that ships this one along with the rest of its 18 skills, 26 commands, 3 agents.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 384 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00384
Opus 5.5	$0.00000	$0.00154
Sonnet 5.5	$0.00000	$0.00077
Haiku 4.5	$0.00000	$0.00038

Security

Grade A, and why

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 2mo 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.

What it actually says

/mpga:plan

Generate an evidence-based implementation plan for the active milestone. Evidence First — no fake docs. Build the wall between modules!

Steps

Start the live board in the browser: mpga board live --serve --open
Read MPGA/INDEX.md for active milestone
Read the milestone's PLAN.md: cat MPGA/milestones/<id>/PLAN.md
Read relevant scope documents based on milestone objective
Spawn researcher plus any needed read-only scout agents in parallel if config.agents.researchBeforePlan is true
Break work into bite-sized tasks (2-10 min each):
- Each task MUST cite exact files to modify (with evidence links)
- Each task MUST cite expected test file locations
- Each task MUST have mechanically verifiable acceptance criteria
- Each task should declare its scope so independent scopes can run in parallel
- One write lane per scope

Create task cards on the board:

mpga board add "<title>" --priority <p> --scope <scope> --column todo

Write the plan to MPGA/milestones/<id>/PLAN.md
Show board: mpga board show

Usage

/mpga:plan
/mpga:plan M001-auth-system

Plan quality criteria

Each task references specific files with evidence links
Acceptance criteria are checkboxes, not prose
No task is more than 10 minutes of work
Dependencies between tasks are explicit
Evidence links expected for each task are listed
Parallel-safe tasks are separated from same-scope write conflicts — Lock her up! (the race condition!)

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.

plan is a command published in the GitHub repository benrben/MPGA (5 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 384 tokens. 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.
