What it does
Nexus Mobile Compat is an agent skill from ProfSynapse/nexus. Keep Nexus loading on mobile and compliant with the Obsidian plugin store — vet a dependency, import without crashing init, confine a vault path, and prove none of it regressed with the reachability checker. Use before adding an npm package or a Node import, when writing to caller-supplied vault paths, when gating a desktop-only feature, when a PDF or worker-backed feature misbehaves, or when the plugin fails to load on a phone.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including reference files (for example `protocols/confine-a-vault-path.md`, `protocols/diagnose-mobile-crash.md` and `protocols/import-without-crashing.md`).
It sits in Documents & Office. It works with npm and Obsidian. The licence is MIT.
When your agent uses it
- Documents & Office work in your project
Example prompts
- “/nexus-mobile-compat”
Requirements
- Python 3
- Node.js
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Read the protocol the table names, in full, before editing anything.
- Whatever the protocol, you MUST run the reachability checker before calling

What it can do on your machine
Read from SKILL.md and the folder at commit f48a4ea. 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:
npmnode
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, 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
Nexus Mobile Compat loads about 1.2k tokens when it runs, and up to ~3.4k if it reads all its reference files. Until then it costs about 113 tokens; SKILL.md has 602 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.

- Keep Nexus loading on mobile and compliant with the Obsidian plugin store — vet a dependency, import without crashing init, confine a vault path, and prove none of it regressed with the reachability checker. Use before adding an npm package or a Node import, when writing to caller-supplied vault paths, when gating a desktop-only feature, when a PDF or worker-backed feature misbehaves, or when the plugin fails to load on a phone.
Nexus mobile & plugin-store safety
Nexus ships isDesktopOnly: false, so main.js runs on phones with no Node.js.
The defect this skill exists to prevent has no compiler and no type behind it: a
static import executes during module init, before any Platform.isDesktop
check, so one import on the startup path takes the plugin down at launch on every
phone — from a diff that looks unrelated.
The reachability checker below is now wired into the repo's own gate: npm run lint runs lint:obsidian (ESLint) then lint:mobile (this checker), and npm run build runs npm run lint first. A violation fails the build. Run the
checker directly anyway while you work — the gate is the floor, not the loop.
Workflow
Pick the row that matches the job and follow that protocol. Do not improvise from this page; each protocol carries the steps and the checks.
| Situation | Protocol |
|---|---|
| Adding or upgrading an npm package | protocols/vet-a-dependency.md |
| Need a Node built-in, a heavy module, or a desktop-only feature | protocols/import-without-crashing.md |
| Writing, reading or deleting at a caller-supplied vault path | protocols/confine-a-vault-path.md |
| About to ship a change that touched imports or the startup path | protocols/verify-mobile-safety.md |
| "It won't load on my phone" / a mobile-only failure | protocols/diagnose-mobile-crash.md |
| Session that used this skill is ending | protocols/self-refine.md |
Read the protocol the table names, in full, before editing anything.
Whatever the protocol, you MUST run the reachability checker before calling the change done — it is the only guard for this defect class:
bash node scripts/check-mobile-imports.mjs . # identical, the way the build invokes it: npm run lint:mobilescripts/check-mobile-imports.mjsin the repo IS the checker — one implementation, edit it there. It was a Python script behind a launcher until 2026-08-15, when Obsidian's community scorecard failed build verification on a clean container that has Node but no Python. A build gate may only depend on what the build already needs.It walks static imports from
src/main.ts, follows noawait import(), and exits non-zero when a Node built-in is reachable from init. Run--helpfor--trace <file>(is this module on the startup path, and via what chain) and--packages(which npm packages init loads).npm run lintnow runs both halves: ESLint for the store rules that are mechanical, then the reachability checker. A green ESLint says nothing about reachability, and a green checker says nothing about the store rules — which is why the composed script runs both, and whynpm run buildcalls it. ESLint additionally hard-errors on Node built-in and Node-dependent package imports undersrc/settings/components/**(issue #221): those shared UI primitives are reachable from init today, but the per-file ban holds even if the import graph shifts. The blocklists are theMOBILE_BANNED_*arrays at the top ofeslint.config.mjs; widen the guard by adding a glob to that block'sfiles.NEVER treat
obsidian dev:mobile onas evidence of mobile safety. It emulatesPlatform.isMobile, touch and layout inside Electron, whererequire('fs')still resolves — this crash class cannot reproduce there. Seereferences/init-order.md.

Map
protocols/the procedures above, each ending at the next one.references/read on demand:init-order.md(why a platform guard below an import is decoration, and what reachability really guarantees),plugin-store-rules.md(the store rules and which are already lint-enforced),pdfjs-in-electron.md(the worker constraint and the single sanctioned entry).- The import-graph checker lives in the repo, not here:
scripts/check-mobile-imports.mjs. Run it; do not reimplement it as a grep — grep cannot see reachability, and this repo has known-correct hits that a grep reports as violations.
Boundaries
The full store guidance lives in docs/obsidian-plugin-guidelines.md; this skill
is the part that bites in practice. Test lanes, the in-app Obsidian CLI loop and
mock-versus-real questions belong to nexus-testing. Storage roots, the event
store and migrations belong to nexus-storage. Release packaging belongs to
nexus-release.
