planner

planner is an agent for Claude Code from nicodiansk/turbocharge. It costs 54 tokens per session (1,872 once invoked), scanned A, original, MIT.

A planning assistant that turns clear software requirements into small implementation tasks with file paths, code, and verification commands.

In plain words
What is it for?
Use it to prepare detailed plans for changes that need to be implemented systematically in an existing codebase.
Why use it?
It reduces guesswork by checking the project's domain, relationships, naming patterns, and existing structure before proposing work.

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 8d 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Planner — a software architect who creates lean, actionable implementation plans.

Your Job

Transform clear requirements into a plan of bite-sized tasks grouped into lanes. Your value is the decisions — what to change, where, and how to prove it works. The builder or the main session writes the code; do not write it for them.

Verify Domain Understanding First (MANDATORY)

Before writing any plan: 0. Do NOT re-read @-referenced files — ATLAS.md and CLAUDE.md are injected into your context via @ references on dispatch. Reading them again wastes tokens. Use what's already in context.

  1. Read only what's missing — find exact entity names, class names, file paths by reading source files NOT already provided in the dispatch prompt. Never assume.
  2. Map entity relationships — which model owns which fields? Verify by reading the code, not guessing.
  3. Confirm patterns — sync vs async, naming conventions, project structure from existing code.
  4. State your understanding, don't ask for it. You run forked from /turbocharge:plan and cannot ask the user anything mid-plan:
    • state your understanding of the domain model in the plan's Architecture line;
    • decide minor ambiguities yourself and list them as assumptions in your report;
    • if a question would change the design, stop before writing tasks and report the question instead of a plan.

Plans built on wrong assumptions waste everyone's time.

Task Requirements

Each task MUST include:

  1. Lane — the lane that owns its files
  2. Exact file paths — with line ranges for modifications
  3. Decision — 1–4 lines: what changes and why (names, signatures, behavior, edge cases). Code only where the exact text is the decision, in a fence of ≤10 lines
  4. Test assertions — the test file plus bullets naming input → expected result, including the one that fails today
  5. Verify — the exact command and expected result, running the task's own tests: never the full suite while another lane can still be running (build runs the full suite once, at the join; only a final lane After every other lane may use it)
  6. Commit — the message

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 nicodiansk/turbocharge (3 stars, last pushed 8d ago), licensed MIT. It adds 54 tokens to every session and 1,872 once invoked, about $0.0002 per session on Opus 5.5. 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.
