turboplan is a skill for Claude Code, Codex from tobihagemann/turbo. It costs 78 tokens per session (538 once invoked), scanned A, original, MIT.

A planning workflow that decides whether a task should be handled directly or documented in a plan file first. It considers the task's size, risk, and unknowns.

In plain words
What is it for?
Use it when deciding how to organise implementation for a feature, fix, or larger project change.
Why use it?
It gives complex or uncertain work a written approach while keeping clear, small changes moving quickly.

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

turboplan 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 9d 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 — 36 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Turboplan

Analyze task complexity to recommend an execution mode, then let the user set the final route.

Categorize the user-supplied task along these dimensions using subjective judgment. This analysis makes the recommendation informed:

  • Scope: single feature / single subsystem vs multi-feature / multi-subsystem
  • Stakes: one-off change vs long-lived project with architectural implications
  • Unknowns: clear approach vs needs exploration and product decisions

Modes are named by what they produce: no plan, or a plan file.

Mode Criteria Route
Direct Clear scope, with any remaining decisions small enough to settle in conversation rather than write down. Aligns on the shape, then implements. Read references/direct-mode.md and follow its steps.
Plan The approach warrants writing down before implementing — to survey patterns, settle architectural decisions, or survive a fresh session. Produces a plan file, however large the work turns out to be. Read references/plan-mode.md and follow its steps.

Recommend and Confirm the Route

Form a recommended route from the dimensions and criteria above. Output the recommendation as text: the recommended mode and a line or two on why it fits over its neighbor.

Then use AskUserQuestion to have the user set the final route. Offer the recommended mode first, marked "(Recommended)", alongside the other mode; the auto-appended "Other" lets the user describe a different path.

Add a third Get a second opinion option whenever committing to the wrong mode would cost a session of rework, and whenever the recommended mode does not earn "(Recommended)" with conviction. It runs the /consult-codex skill for the soundest route given the task's scope, stakes, and unknowns. Then resolve the route with that answer in hand, re-asking when the choice stays the user's.

Carry the confirmed route into its reference file from the table above and follow its steps.

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.
