plan

plan is a skill for Claude Code from ashtonian/llm-init. It costs 9 tokens per session (335 once invoked), scanned A, original, MIT.

A guide for choosing a planning template and creating a filled-in plan file for a software project or change. The templates cover new projects, full-stack features, bugs, reviews, requirements, and code generation.

In plain words
What is it for?
Use it to start a project plan, plan a feature or bug fix, organize requirements, or prepare spec-first code generation.
Why use it?
It gives development work a written objective and an initial sequence of steps before implementation. The plan is shown to the user for review first.

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 1mo 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

Help select the right plan template and create a plan file.

Instructions

  1. Read the available templates in docs/spec/.llm/templates/:

    Template Use When
    idea.plan.llm Starting from scratch -- idea to working project
    fullstack.plan.llm Full-stack feature (DB -> API -> UI -> E2E)
    feature.plan.llm Backend-focused feature (6 phases)
    review.plan.llm Review/iteration cycle with quality gates
    bugfix.plan.llm Bug investigation and fix
    self-review.plan.llm Audit the LLM orchestration system
    codegen.plan.llm Spec-first code generation (requires spec before code)
    requirements.plan.llm Multi-session requirement gathering to produce a spec
    plan.template.llm Generic -- anything else
  2. Based on the user's description, recommend the best template.

  3. Create the plan file:

    cp docs/spec/.llm/templates/<template> docs/spec/.llm/plans/<name>.plan.llm
    
  4. Pre-fill the plan with:

    • Metadata (timestamp, status: planning)
    • Objective from the user's description
    • Initial implementation steps
  5. Present the plan to the user for review before proceeding.

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.
