What it does

Breaks a spec issue into tracer-bullet sub-issues with blocking edges. Each sub-issue has the size of one agent 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 Issues

10Turn a spec into issues that an agent can take cold and complete — **tracer bullets**. Publication goes through the tracker doc, docs/TRACKER.md.
11
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. **Gather.** Fetch the spec issue: the reference in the argument, or else the spec issue that this session published. If neither exists, stop, and point the user to the create-specification skill. Explore the code that the spec touches, if you did not do this before. This step is complete when you can state each requirement without a second read of the spec.
17
182. **Slice.** Write the draft of the issue set. Follow these rules:
19 - Each slice cuts a narrow but **complete** path through each layer that it needs (schema, logic, API, UI, tests). A slice is vertical, never one layer wide.
20 - A completed slice is demoable or verifiable alone. Its size is one fresh agent session.
21 - An acceptance criterion that verifies computed behavior includes a worked example: concrete input → expected output. The example is the independent source of truth that the tests assert against.
22 - If the spec leaves a question open, and only an investigation or code that runs can settle it, make a research issue or a prototype issue. That issue blocks the slices that need its answer. The question is then settled in the tracker, not discovered during implementation.
23 - Prefactor slices come first: slices that make the change easy come before slices that make the change.
24 - Give each slice its blocking edges. Add only the issues that truly gate it.
25 - If the user must approve a slice's result before its dependents unblock, add a body line that says: closure waits for user review. The session that implements the slice then applies needs-review, and does not close. (The semantics are in the tracker doc's label list.) The default is no gate.
26 - **Wide refactors are the exception** to vertical slices. One mechanical change with a blast radius across the codebase (a column rename, a retype of a shared symbol) gets the **expand–contract** sequence: an *expand* slice adds the new form parallel to the old form; *migrate* slices move the call sites in batches (one batch for each package or folder), each blocked by the expand slice; a *contract* slice deletes the old form, blocked by each migrate slice.

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.

≈70
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
980
on trigger
The instruction body and 2 supporting files, read only when the skill fires.
0.53%
of a 200k window
Ten skills this size would take about 5% of the window before you open a file.
050k100k150k200k context window

1.1k 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

3 files, 4.2 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md4.0 kB
  • agents/openai.yaml0.1 kB
  • assets/templates/sub-issue.md0.1 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 3 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 Issues · 1.1k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/create-issues/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/create-issues" ] && { [ ! -e .claude/skills/create-issues ] || { mv .claude/skills/create-issues "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/create-issues" .claude/skills/ && echo "Installed .claude/skills/create-issues"
On Windows, or any OS with Node 20+
npx mcprush@latest skill add builtbystef/create-issues

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-issues/ 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/create-issues/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/create-issues" ] && { [ ! -e ~/.claude/skills/create-issues ] || { mv ~/.claude/skills/create-issues "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/create-issues" ~/.claude/skills/ && echo "Installed ~/.claude/skills/create-issues" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/create-issues/ 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.
