thorough-plan

thorough-plan is a skill for Claude Code from bengous/claude-code-plugins. It costs 94 tokens per session (1,461 once invoked), scanned A, original, MIT.

A planning aid that explores an unclear or unfamiliar task before producing a detailed plan. It checks ambiguity, scope, risk, and novelty to decide how much investigation is needed.

In plain words
What is it for?
Use it for complex or underspecified changes that may touch several files, systems, or unfamiliar libraries.
Why use it?
It reduces the chance of committing to a plan before the important requirements, code, or technical choices are understood.

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

thorough-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 yesterday.

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

Thorough Plan

An adaptive exploration loop that prevents premature planning. Builds context through codebase exploration, targeted research, and user questions — then hands off to the normal planning flow.

This is not a planning framework. It's a context amplifier.

This skill injects judgment: explore what you can, ask what you must, stop when you know enough.

Triage

Read the brief. Evaluate along these dimensions:

  • Ambiguity — multiple valid interpretations? unclear boundaries?
  • Scope — how many files/systems? cross-cutting concerns?
  • Risk — breaking changes? security? data migration?
  • Novelty — unfamiliar library? new pattern for this codebase?

Low on all → skip exploration. State your understanding of the task and proceed directly to planning. Don't explore for the sake of exploring.

High on any → enter the exploration loop. Focus exploration on the dimensions that are actually uncertain.

  • Ambiguity: low — intent is clear
  • Scope: medium — needs new command + script, touches plugin structure
  • Risk: low — read-only git operations, no data loss
  • Novelty: low — similar commands exist in git/

→ One focused Explore agent on git/ patterns, then proceed to planning. No user questions needed.

  • Ambiguity: high — "redesign" could mean anything from a new config format to a complete architecture change
  • Scope: high — touches every plugin
  • Risk: high — breaking change for existing plugins
  • Novelty: medium — depends on what approach is chosen

→ Explore current config patterns across plugins, then ask the user what "redesign" means to them before exploring further.

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.

prep

Spec a ticket before it is dispatched. Brainstorms it, decides everything it can recommend an answer for, asks a present human about the little that survives, and leaves the spec, the decisions and anything still open as one ticket comment. No worktree, no branch, no pull request, and the ticket stays where it was.
