What it does
Tanstack Query is an agent skill from exceptionless/Exceptionless. Manage Svelte API queries, mutations, cache updates, and WebSocket invalidation.
Its SKILL.md is about 560 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 Backend & APIs, covering Realtime and WebSockets. It works with TanStack and Svelte. The repository describes itself as: Exceptionless application. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Realtime and WebSockets
Example prompts
- “/tanstack-query”
What it can do on your machine
Read from SKILL.md and the folder at commit 300e8ca. 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
Tanstack Query loads about 562 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 261 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
- Manage Svelte API queries, mutations, cache updates, and WebSocket invalidation.
TanStack Query
Centralize API calls in each feature's api.svelte.ts, using @tanstack/svelte-query and @exceptionless/fetchclient.
Use the current organization and webhook implementations under src/Exceptionless.Web/ClientApp/src/lib/features/ as examples. Preserve their response/error types and signal handling.
- Share a feature's
queryKeysfactory across queries, mutations, and invalidation. - Name operations
get{Resource}Query,post{Resource}Mutation,patch{Resource}Mutation, anddelete{Resource}Mutation. - Gate queries on required authentication or identifiers.
- Pass the query cancellation signal through the fetch client.
- For optimistic updates, cancel competing queries, snapshot the cache, restore on failure, and reconcile with server state after completion.
- Wire WebSocket changes through the feature's invalidation helper. Match invalidation scope to the message identifiers.
Verify failure recovery and relevant cache interactions, not just the successful response.
Mutation and cache lifecycle
Keep reactive query options in the factory passed to createQuery or createMutation, following the current feature implementation. Include identifiers and relevant query parameters in its key factory so distinct results do not share a cache entry.
For an optimistic mutation, onMutate cancels affected in-flight queries and saves the previous value before updating the cache. onError uses that context to roll back; completion reconciles affected queries with server state, commonly through onSettled. Preserve unrelated cache entries and consider overlapping mutations before restoring an older snapshot.
Await invalidation or refetching when the calling UI depends on it before closing or navigating. Match the existing feature's FetchClientResponse and ProblemDetails handling instead of assuming every request throws or every mutation returns an unwrapped model.
WebSocket invalidation must use the same key factories as queries. Inspect both the feature helper and its caller when changing message handling; verify identifier-specific and collection updates.
