What it does
Sync URL Navigation is an agent skill from swyxio/skills. Syncs URL query parameters with app navigation, tabs, and filter state so views are bookmarkable and shareable. Use when building or changing frontend routing, filters, tabs, modals, deep links, browser back/forward, or when the user asks to remember navigation in the URL, sync state to query params, or make screens linkable.
Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile. The repository describes itself as: Agent skills for Claude Code and other AI agents. The licence is MIT.
When your agent uses it
- Changing frontend routing
- Browser back/forward
- The user asks to remember navigation in the URL
- Sync state to query params
Example prompts
- “Use the sync-url-navigation skill to sync URL query parameters with app navigation, tabs, and filter state so views are bookmarkable and shareable”
- “/sync-url-navigation”
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- Single routing module — readRouteState(search) + writeRouteState(state) (or equivalent). Parse and validate all params in one place.
- Initialize store from URL on load — signals get initial values from readRouteState(), not hardcoded defaults alone.
- Setter functions — e.g. setDataTableId, setListFilter: update signal(s), then call writeRouteState. UI never mutates filters without…
- history.replaceState for in-app changes (matches existing preference: shareable URL without cluttering history on every keystroke). Use…
- popstate listener — hydrateRouteFromUrl() re-reads params on browser back/forward.
- View-scoped params — when switching top-level view, drop params that only apply to the other view (avoid stale q meaning different things).
- Inbound deep links — support stable aliases (focus=assignment:asn_…) that map to table + filter; clear alias once the user changes nav…
- Tests — pure tests for parse/read (invalid ids, focus format, view-specific q).
What it can do on your machine
Read from SKILL.md and the folder at commit 038ef34. 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
Sync URL Navigation loads about 963 tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 457 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.

- description
- Syncs URL query parameters with app navigation, tabs, and filter state so views are bookmarkable and shareable. Use when building or changing frontend routing, filters, tabs, modals, deep links, browser back/forward, or when the user asks to remember navigation in the URL, sync state to query params, or make screens linkable.
Sync URL to navigation and filter state
User preference
Always keep meaningful UI navigation and filtering state in the URL (query params). Reloading, sharing, or opening a link should restore the same screen—not only the top-level route.
The user expects this by default on web apps unless they say otherwise.
What to put in the URL
| State | Include when |
|---|---|
| Active view / tab / mode | User can switch between distinct screens |
| Sub-navigation (sidebar table, nested tab) | Second-level nav exists |
| Search / filter text | User can filter lists or tables |
| Structured filters (dropdowns) | Each materially changes what's shown |
| Pagination cursor (optional) | Only if bookmarking a page matters; prefer omitting page=1 |
| Selection / editor (optional) | Only for shareable deep links (?focus=type:id) |
Omit defaults from the URL (e.g. default tab id, empty q) to keep links clean.
Implementation pattern
- Single routing module —
readRouteState(search)+writeRouteState(state)(or equivalent). Parse and validate all params in one place. - Initialize store from URL on load — signals get initial values from
readRouteState(), not hardcoded defaults alone. - Setter functions — e.g.
setDataTableId,setListFilter: update signal(s), then callwriteRouteState. UI never mutates filters without syncing the URL. history.replaceStatefor in-app changes (matches existing preference: shareable URL without cluttering history on every keystroke). UsepushStateonly if the user explicitly wants full history stacks per filter change.popstatelistener —hydrateRouteFromUrl()re-reads params on browser back/forward.- View-scoped params — when switching top-level view, drop params that only apply to the other view (avoid stale
qmeaning different things). - Inbound deep links — support stable aliases (
focus=assignment:asn_…) that map to table + filter; clear alias once the user changes nav manually. - Tests — pure tests for parse/read (invalid ids, focus format, view-specific
q).
Show full SKILL.md (179 more words)Show less
Param naming (conventions)
- Short, stable names:
view,day,table,q,area,status - Avoid overloading one key across views with different semantics unless documented
- Prefer ordinal in URL when UI shows "Day 1" (
day=3); accept raw ids for forward-compat - Document params in a short table in the PR or README when adding a new screen
Checklist for new screens
- Every navigational control updates the URL via a setter
- Load path restores state from URL
- Invalid param values fall back safely (don't crash)
- Back/forward works (
popstate) - Example URL documented or covered by a test
Reference implementation
The AI Engineer World's Fair 2026 schedule admin app implements this in:
src/frontend/routing.ts— parse/write query paramssrc/frontend/store.ts—setViewMode,setDataTableId,setDataFilter,setListFilter,hydrateRouteFromUrltests/routing.test.ts— focus links and view-specific filters
Copy the pattern, not necessarily the exact param names, when working in other repos.
Anti-patterns
- Filters only in component
useState/ signals with no URL sync - Syncing URL on initial load but not when user changes filters
- Putting secrets or PII in query params
- Different param names per view for the same concept without clearing on view switch
