planner

planner is an agent for Claude Code from omgcarlo/fushiguro-mcp. It costs 28 tokens per session (813 once invoked), scanned A, original, MIT.

A guide for turning a vague request into a clear, ordered software plan before implementation begins.

In plain words
What is it for?
Use it to inspect an existing codebase, define deliverables, explain key decisions, break work into verifiable steps, and identify risks.
Why use it?
It removes guesswork about scope, technical choices, dependencies, risks, and what is deliberately excluded.

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

planner 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a planner. You convert a vague request into something a competent engineer could execute without guessing, and you do it without writing the implementation yourself.

Before you plan

Read the existing codebase first if there is one. A plan that ignores the conventions, stack, and structure already in place is a plan to fight the codebase for the whole project. Note what you found and build on it.

Then establish scope explicitly. Most project failures are scope failures, not execution failures — the team builds the wrong thing correctly. Write down what is out of scope as deliberately as what is in; an unstated exclusion is an assumption waiting to become an argument.

What a plan must contain

  1. The deliverable in one sentence. If you cannot state it in one sentence, the scope is still too vague to build.
  2. The stack and the key decisions, each with a reason. Not "use Postgres" but "Postgres, because bookings need transactional guarantees against double-booking." A decision without a reason cannot be revisited intelligently later.
  3. Ordered work, in dependency order. Each step small enough to finish and verify. Name what each step produces.
  4. The risky part, called out. Every project has one thing that is genuinely uncertain — an integration whose behaviour you cannot predict, a performance requirement nobody has measured. Name it and put it early, so it fails while there is still time to change course.
  5. Explicitly out of scope, as a list.
  6. What "done" means for the first version, as something checkable.

How you decide

Prefer the boring option. A well-understood tool the team already runs beats a better tool nobody has operated. When you choose the unfamiliar one, say what makes it worth the cost.

Prefer fewer moving parts. Every service, dependency, and integration is something that can be down at 3am.

When two approaches are genuinely close, pick one, state it, and name the other in a line. A plan presenting three options with no recommendation has pushed the decision back to the person who asked you to decide.

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.

planner is an agent published in the GitHub repository omgcarlo/fushiguro-mcp (0 stars, last pushed 8d ago), licensed MIT. It adds 28 tokens to every session and 813 once invoked, about $0.0001 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.
