plan

plan is a skill for Claude Code, Codex from infohata/mind-vault. It costs 89 tokens per session (3,733 once invoked), scanned A, original, Apache-2.0.

A planning guide that turns an idea or rough feature description into a detailed technical plan saved with the project records.

In plain words
What is it for?
It helps prepare work for a developer or coding agent, including deciding expected behavior and moving the original idea into its archived project folder.
Why use it?
It fills in missing requirements, boundaries, and test scenarios so implementation does not depend on guesswork.

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 5d 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 — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.

plan

Second stage of the five-stage sprint workflow (idea → brainstorm/plan → work → review → compound). Turns an atomic IDEA file or a rough feature description into a durable plan that an agent — or a human — can execute from without re-inventing product behavior, scope boundaries, or test scenarios.

This skill merges the brainstorm + plan stages from CE. When input is already specific (a filled-out IDEA file, a bug report with clear repro), the skill skips straight to plan authoring. When input is thin (a one-line description, an IDEA stub), a thin-input bootstrap fires — the interactive brainstorm front-end — before the plan is written. Brainstorming is a mode, not a separate skill. /brainstorm is an alias for /plan.

This skill does not write code, run tests, or modify project source. It does, however, author the plan artifact and — per RULE_ideas-location-status and step 6 below — trigger the single git mv that moves the source IDEA file from docs/ideas/ into its docs/archive/YYYY-MM-idea-NNN-<slug>/ dir. The plan artifact itself lands in that same archive dir (emitted by step 7). Execution belongs in /work (the next stage).

When to use

TRIGGER when:

  • user says "plan this", "write a tech plan", "plan the implementation", "how should we build X", "break this down", "what's the approach for Y", "let's brainstorm X", "help me think through X", "deepen the plan"
  • user references an existing IDEA file by slug (/plan sprint-workflow) or path
  • an IDEA file was just created by /idea and the natural next step is to turn it into a plan
  • the user provides a bug report, a feature idea, or a rough description that would benefit from structured decomposition before execution

SKIP when:

  • the work is a one-off trivial fix (typo, one-line bugfix) that a plan would over-engineer
  • the user wants to start coding immediately on something well-understood — route to /work directly
  • the user is still exploring "what to build" at a portfolio level with no single target in mind — route to /idea (or multiple /idea invocations) to surface candidates first

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.
