What it does

Interviews the user until a goal is fully planned and ready for a specification. If the goal is too large for one session, creates a roadmap: a DAG of grill, research, prototype, and task sessions. The advance-plan skill then works the roadmap, one node for each session.

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

8# Create Plan

10The user has a goal, but is not sure how to move forward. Interview the user, and develop a plan together. Find facts yourself when they are needed. The user makes the decisions. Explore the full decision space. Identify the choices that matter. Then decide honestly: can the remaining planning work occur in this session, or must it be divided? A planning session decides. It never implements.

12If the docs/ folder or docs/TRACKER.md is missing, stop. Ask the user to invoke the set-up-for-agents skill.

14## Steps
15
161. **Name the goal.** Write one or two sentences: what "done" looks like, from the user's point of view. This step is complete when the user agrees with your statement of the goal. Each later question relates back to this goal.
17
182. **Scout before you ask.** Find facts yourself. The user makes the decisions. Never ask the user a question that the repository can answer. Send read-only sub-agents to map the applicable code: what exists today in the goal's area, its seams, and its tests. Read docs/GLOSSARY.md, docs/ARCHITECTURE.md, and the ADRs in the area yourself. They are short, and they feed the interview directly. Delegation of the code walk matters here more than anywhere. The plan lives in this session's conversation, so keep the context for decisions and findings, not for file contents. If the host has no sub-agents, walk the code yourself, with the same economy: carry forward findings, not file contents. This step is complete when you know what exists today in the goal's area.
19
203. **List the open decisions.** Cover the full decision space widely. Do not go deep on one thread. Include: scope edges, data shapes, interfaces and seams, new dependencies, the call paths that the change alters at module boundaries, failure modes, migration, and UX. Then tell the user which case applies, and why:
21 - **Plannable here** — the full set of decisions, plus the code that they touch, fits in this session (approximately 200k tokens). No decision waits on outside knowledge, a prototype, or work that must occur first. → Continue to step 4.
22 - **Too large** — the goal becomes a **roadmap**: a DAG of nodes in the tracker. Each node has the size of one question and one fresh session. Read [../advance-plan/SKILL.md](../advance-plan/SKILL.md), and follow its "Create the roadmap" section. The sharp decisions become nodes. The remainder goes in the Frontier. Then stop.
23
24 This step is complete when you told the user which case applies, and why.
25
264. **Interview.** Read [../grill-me/SKILL.md](../grill-me/SKILL.md), and follow it. Limit the interview to the goal and to the open decisions from step 3. This step is complete when no decision remains that would make an implementer stop and ask.

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈90
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
885
on trigger
The instruction body and 1 supporting file, read only when the skill fires.
0.49%
of a 200k window
Ten skills this size would take about 5% of the window before you open a file.
050k100k150k200k context window

975 tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Small enough to keep loaded permanently without thinking about it.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

2 files, 3.9 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md3.7 kB
  • agents/openai.yaml0.2 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 2 files you can review in full before installing. The MIT licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# Create Plan · 975 tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/builtbystef-create-plan/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/create-plan" ] && { [ ! -e .claude/skills/create-plan ] || { mv .claude/skills/create-plan "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/create-plan" .claude/skills/ && echo "Installed .claude/skills/create-plan"
On Windows, or any OS with Node 20+
npx mcprush@latest skill add builtbystef/create-plan

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/create-plan/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/builtbystef-create-plan/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/create-plan" ] && { [ ! -e ~/.claude/skills/create-plan ] || { mv ~/.claude/skills/create-plan "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/create-plan" ~/.claude/skills/ && echo "Installed ~/.claude/skills/create-plan" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/create-plan/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
