plan

plan is a skill for Claude Code, Codex from ohm41321/luciazero. It costs 47 tokens per session (264 once invoked), scanned A, original, MIT.

A planning guide for new features, large refactors, unclear tasks, or changes spanning several modules. It defines the scope, proof of success, reversible steps, risks, and when to ask for a decision.

In plain words
What is it for?
Use it to plan risky or multi-module changes, define tests and verification commands, and decide whether clarification or approval is needed.
Why use it?
It turns uncertain work into checkable steps and makes compatibility, migration, and rollback concerns visible before implementation begins.

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

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 3d 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

Plan

Use the lightest plan that removes uncertainty; do not pause by default.

1. Bound the work

State goal/non-goals, modules, public interfaces, and config keys. Separate assumptions/facts. Inspect repository before trusting guesses.

2. Define proof

For every requirement, name an observable pass/fail condition and the command or inspection that tests it. Never invent exact output. Add the smallest red-before-green test for missing coverage; include full verification at closeout.

3. Choose reversible steps

Use independently checkable edits; name compatibility risks, data or contract migrations, rollback points, and unrecoverable state.

4. Decide whether to pause

Ask for approval only if ambiguity changes the result or the action is high-stakes, destructive, changes a public contract, expands scope, deploys, spends money, or affects production. Ask one decision-shaped question. Otherwise, show the concise plan and proceed. Update it when evidence changes.

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.
