Guidance for AI coding agents (Claude Code, Codex, Cursor, Copilot and others) working with this repository. People should start at README.md. This repo is a skill library: 57 Agent Skills and one subagent for building WebXR games and apps with Meta's Immersive Web SDK (IWSDK), testing them on Meta Quest and shipping them on the Meta Horizon Store as PWAs. It holds no app code. Every folder name equals its skill's name:. Every third-party folder has a SOURCE.md. 1. Ask…

- Installs packages
Where files are headingNew AGENTS.md files have more rules about keeping secrets out of the code, and fewer about code style.
Of the AGENTS.md files we read, the 31,542 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.
In this repository58 other files it gives its agents.

The file
We split this AGENTS.md into the rules it gives an agent
8 rules. About 0 are common, 0 are distinctive, and 8 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈0
Distinctive · estimate
This author's own choices. Worth a look.
8
Very specific
Tied to their project's names, files or tools. Probably skip.

Start with iwsdk-dev-workflow (the router).

Never: put keystores, key passwords, app secrets or deploy tokens in public/, dist/, git or chat output.
- Very specific: line 54
Prefer the iwsdk-* and horizon-* skills over Meta's hz-iwsdk-webxr (IWSDK 0.4 era) and hz-store-submit / hz-store-pwa where they differ.
- Very specific: line 65
New or moved skills: add the path to exactly one bundle in .claude-plugin/marketplace.json (iwsdk-official paths are relative to …
- Very specific: line 76
Never commit .env files, keystores (*.keystore, *.jks) or credentials.
≈ “Common” is an estimate: at least 1 in 5 of the 40,246 AGENTS.md files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

If a user asks you to install skills from this repo
- Ask where (one project or every project) and which bundles. Default to
iwsdk-corein the project. - Check for a scaffolded project first. If the project has
.claude/skills/iwsdk-dev/(made bynpm create @iwsdk), it already has theiwsdk-officialskills and agent: don't install that bundle. Also check for Meta'smeta-vrplugin and for Meta skills installed bymetavr init/metavr skills install(runmetavr skills status; they live in~/.agents/skills), which duplicate the Meta skills. - Pick one method. As Claude Code:
claude plugin install iwsdk-core --marketplace mirzaaghazadeh/iwsdk-webxr-skills --scope project. Otherwise./install.sh --project <dir> <bundle>from a clone, ornpx skills add/gh skill install(see docs/install.md). - Confirm before changing user-level settings (
--scope user,~/.claude/). - Tell the user to start a new session or run
/reload-plugins, then suggest: "Use iwsdk-dev-workflow to plan my WebXR game."
If you are using these skills in an IWSDK project
- Start with
iwsdk-dev-workflow(the router). For any change to app code, scenes, models or UI, invokeiwsdk-devfirst. For Quest or store facts,hz-quest-verify-first. - Prove it in the runtime, then on the device: typecheck,
npx @iwsdk/cli dev up, ECS/XR evidence (xr status), then the headset. A compile or a flat screenshot isn't proof. - Ask before: deploying to a public host, any Store upload or channel promotion, creating a
signing key,
npm i -g, Playwright browser downloads,adapter sync(writes agent config) and--allow-browser-automation. - Never put keystores, key passwords, app secrets or deploy tokens in
public/,dist/, git or chat output. After every deploy, check thathttps://<domain>/android.keystorereturns 404. - Prefer the
iwsdk-*andhorizon-*skills over Meta'shz-iwsdk-webxr(IWSDK 0.4 era) andhz-store-submit/hz-store-pwawhere they differ. See bothERRATA.mdfiles.
If you are changing this repository
- Don't edit files under
skills/iwsdk-official/,skills/meta-official/or third-party folders inskills/community/. Refresh them from upstream as theirSOURCE.mddescribes, and record disagreements in that folder'sERRATA.md. - Custom skills (
skills/custom/): keepname:equal to the folder name, keeplicense: MIT, themetadata.authorblock and the "Made by" line, cite a source for every API, number or flag, mark anything unconfirmed as unverified, and updateLast verified:. - New or moved skills: add the path to exactly one bundle in
.claude-plugin/marketplace.json(iwsdk-officialpaths are relative to./skills/iwsdk-official), add a row to the README catalog, and for third-party skills addLICENSE/NOTICE, aSOURCE.mdand a row inTHIRD_PARTY_NOTICES.md. See CONTRIBUTING.md. - Check before committing:
claude plugin validate . --strict ./install.sh --list ./install.sh --project /tmp/skilltest --dry-run all - Never commit
.envfiles, keystores (*.keystore,*.jks) or credentials..gitignoreblocks the common ones.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
