plan

plan is a skill for Claude Code, Codex from lisihao/Solar. It costs 15 tokens per session (336 once invoked), scanned A, original, MIT.

A sprint-planning workflow that turns a goal into a product requirements document, smaller work slices, dependencies, delivery checks, and a rollback plan. A sprint is a short, fixed development cycle.

In plain words
What is it for?
Use it to create PRDs, implementation plans, work-slice specifications, dependency diagrams, gate checklists, and rollback plans.
Why use it?
It helps turn vague intent into work that can be assigned, checked, and stopped safely when conditions are not met. It also exposes dependencies and risks 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 today.

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

Skill: plan

Turn user intent into a structured PRD, slice topology, and per-slice dispatch plan.

Trigger

User says: 写计划, 制定计划, /plan, Sprint planning

Steps

  1. Clarify intent — ask for outcomes, constraints, timeline if missing
  2. Draft PRD — Non-Negotiables, Target Architecture, Deliverables, Gates
  3. Slice topology — identify independent write scopes; draw dependency DAG
  4. Per-slice spec — Owner, Done conditions, Stop conditions, Round-retry trigger
  5. Gate checklist — G0..Gn with fail action
  6. Write plan.md — persisted to sprint directory

Output format

## 0. Slice Topology (DAG)
## 1. Slice Specs (S0..Sn)
## 2. Product Gates (table)
## 3. Risk Register
## 4. Rollback Plan

Done when

  • plan.md passes schema gate (变更文件列表 + 技术方案 sections present)
  • All slices have exclusive write scopes with no overlap
  • Gate fail actions are specific (stop / rollback / no-release)

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.

plan is a skill published in the GitHub repository lisihao/Solar (2 stars, last pushed 21d ago), licensed MIT. It adds 15 tokens to every session and 336 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
