plan-and-apply

plan-and-apply is a skill for Claude Code, Codex from wangbin3162/agents-skills. It costs 107 tokens per session (1,472 once invoked), scanned A, original, MIT.

A guided workflow for analysing a non-trivial coding task, planning it in small steps, applying the changes, and checking the result.

In plain words
What is it for?
Planning multi-file changes, refactors, migrations, and other tasks that need staged implementation, progress tracking, and verification.
Why use it?
It reduces scope drift, premature edits, oversized rewrites, and unsupported claims that a change is complete.

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-and-apply 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 2mo 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.

The opening of the file, as written. The whole thing — 226 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plan And Apply

This skill is an upper-layer execution workflow for non-trivial development tasks.

It exists to stop four common failures:

  • changing code before understanding the task
  • drifting outside the requested scope
  • doing large rewrites when a local fix is enough
  • claiming completion without verification

Use it to control execution rhythm. Do not use it for simple one-step questions or tiny edits that do not need planning.

When to use

Use this skill when any of these are true:

  • the user says 先分析、先规划、不要直接改
  • the task spans multiple files or modules
  • the task is a migration, refactor, or structured feature implementation
  • the task needs a clear task list, progress tracking, or staged rollout
  • the user cares about strict boundaries, minimal change, or explicit regression checks

Do not use this skill when:

  • the user only wants explanation or brainstorming
  • the change is trivial, isolated, and low risk
  • the task is pure review with no implementation

Core promise

Follow this order unless the user explicitly asks for a narrower path:

  1. Read rules first
  2. Clarify task scope and constraints
  3. Decide whether planning is required
  4. Break work into the smallest viable slices
  5. Apply only the current slice
  6. Verify the change and do regression checks
  7. Close out with result, validation, and remaining risk

Step 1: Read rules first

Before implementation, read the project-level instructions that control behavior.

Priority order:

  1. lessons.md
  2. AGENTS.md
  3. task-specific rule files mentioned by the user
  4. relevant reference implementation or old version

If there is no lessons.md, continue without blocking. Do not invent one.

Step 2: Clarify the task

Before changing anything, answer these questions from local context:

  1. What is the actual requirement?
  2. What constraints did the user set?
  3. What are the main risks?
  4. What is the simplest viable approach?
  5. How will the result be verified?

If a key constraint is missing and guessing would be risky, ask a short direct question. Otherwise, proceed with the safest reasonable assumption.

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.
