What it does

Plan In Files is an agent skill from OneWave-AI/claude-skills. Use for any task that spans more than a couple of steps, files, or sessions — refactors, migrations, multi-file features, anything that must survive a context reset or crash. Trigger when the user asks for a plan, says "keep track of this", "don't lose the thread", or when a task is large enough that forgetting step four is likely.

Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Refactoring. The repository describes itself as: 200+ production-ready Claude Code skills for sales, marketing, design, engineering, and AI agent architecture. Built and maintained by OneWave AI. The licence is MIT.

When your agent uses it

  • Any task that spans more than a couple of steps
  • Sessions — refactors
  • Multi-file features
  • Anything that must survive a context reset

Example prompts

  • “keep track of this”
  • “t lose the thread”
  • “/plan-in-files”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Write it. Show it to the user before executing when the work is large or destructive.
  2. Do one step.
  3. Tick the box in the file, immediately. Not at the end — a crash between step three and the end loses everything.
  4. When reality disagrees with the plan, edit the plan. A plan you silently abandoned is worse than no plan.
  5. Append surprises to Notes as you hit them. That is where the next session's time savings live.

What it can do on your machine

Read from SKILL.md and the folder at commit fc5b785. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Plan In Files loads about 802 tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 423 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~802

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use for any task that spans more than a couple of steps, files, or sessions — refactors, migrations, multi-file features, anything that must survive a context reset or crash. Trigger when the user asks for a plan, says "keep track of this", "don't lose the thread", or when a task is large enough that forgetting step four is likely.

Plan in Files

A plan that lives in the conversation dies with the conversation. A plan that lives in a file survives a crash, a /clear, a laptop reboot, and a different person picking the work up on Monday.

Core Behavior

Before starting multi-step work, write the plan to disk. Update it as you go. The file is the source of truth about progress — not memory, not the chat.

Default location: PLAN.md at the repo root for one-off work, or docs/plans/<yyyy-mm-dd>-<topic>.md when the repo keeps plan history. Gitignore it or commit it — ask once, then follow the repo's convention.

Plan Shape

markdown
# <Task> — plan

**Goal:** <one sentence, in the user's words>
**Done when:** <the observable condition that ends this work>

## Constraints
- <the things that must stay true: no API break, no new deps, ships today>

## Steps
- [ ] 1. <action> — `path/to/file`
- [ ] 2. <action> — `path/to/file`
- [ ] 3. <action> — verify with `<command>`

## Notes
<discoveries, gotchas, things that turned out to be false>

## Log
- <date/time> — <what happened>

Each step is one action on a named file or a named command. "Refactor the auth layer" is not a step; "move verifyToken out of api/auth.ts into lib/token.ts and update the three imports" is.

Working the Plan

  1. Write it. Show it to the user before executing when the work is large or destructive.
  2. Do one step.
  3. Tick the box in the file, immediately. Not at the end — a crash between step three and the end loses everything.
  4. When reality disagrees with the plan, edit the plan. A plan you silently abandoned is worse than no plan.
  5. Append surprises to Notes as you hit them. That is where the next session's time savings live.

Rules

  • Never tick a box for work you have not verified. "Edited the file" is not "step done" if the step said the tests pass.
  • Never fake progress to make the plan look finished. An honest half-done plan is useful; a dishonest complete one is a trap.
  • Keep the plan under a page. A plan longer than the work is a symptom of avoiding the work.
  • If a step turns out to be five steps, split it in the file before continuing.
  • When work finishes, write one closing line in the Log and leave the file. It becomes the record of why the code looks the way it does.

Resuming

When picking up an existing plan file:

  1. Read it.
  2. Verify the ticked steps against reality — git log, git diff, run the tests. Ticked does not always mean true.
  3. Correct the file if it lied.
  4. Start at the first genuinely unfinished step.

When Not to Use This

A single-file edit, a one-line fix, a question. Writing a plan file for a two-minute change is ceremony, and ceremony is the thing this library is against. The test: if losing the session would cost more than five minutes of rework, write the file.
