What it does
Xstate Store is an agent skill from pedronauck/skills. Build, test, integrate, or migrate XState Store v4: transitions, effects, schemas, selectors, atoms, extensions, React bindings, and fromStore. Excludes XState state-machine design, other stores, and Query server state.
Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files (for example `references/effects-and-events.md`, `references/extensions.md` and `references/migration-v4.md`).
It works with React. The repository describes itself as: My personal favorite skills.
Example prompts
- “/xstate-store”
What it can do on your machine
Read from SKILL.md and the folder at commit 0422940. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Xstate Store loads about 841 tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 58 tokens; SKILL.md has 335 words of instructions outside code blocks.
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 335 words (~841 tokens).
“Targets @xstate/store v4 and @xstate/store-react v2 (TypeScript 5.4+). Read the reference matched by the API or behavior being changed. Load adjacent references only for concerns the change crosses; reuse relevant context already read.”

With the skills CLI, run `npx skills add pedronauck/skills --skill xstate-store -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/xstate-store, .gemini/skills/xstate-store, .github/skills/xstate-store and .opencode/skills/xstate-store in your project.
What does Xstate Store need to run?
SKILL.md names no scripts, command-line tools or credentials: Xstate Store is instructions for the agent only.
Does Xstate Store access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

How many tokens does Xstate Store use?
About 841 tokens (SKILL.md is roughly 3.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 11k tokens, read only when the agent opens those files.
