What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00023 | $0.00293 |
| Opus 5.5 | $0.00009 | $0.00117 |
| Sonnet 5.5 | $0.00005 | $0.00059 |
| Haiku 4.5 | $0.00002 | $0.00029 |
Grade A, and why
tanstack-start scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
TanStack Start Patterns
Server Functions
- Define with
createServerFnfrom@tanstack/react-start - Use
.validator()for input validation (e.g. with zod) - Use
.handler()for the implementation - Server functions run on the server only — safe for DB access and secrets
Router
- File-based routing in
src/routes/ - Use
createFileRoutefor route definitions - Use
loaderfor server-side data fetching (runs on server) - Use
beforeLoadfor auth guards and redirects - Route context flows from
__root.tsxto child routes
Query
- Use
queryOptionsto define reusable query configs - Use
useSuspenseQueryin components for data fetching - Invalidate queries after mutations with
queryClient.invalidateQueries() - TanStack Query handles caching, deduplication, and background refetching
Key Conventions
- Path alias:
@/→apps/web/src/ - Route files:
src/routes/<path>.tsx - Layouts:
src/routes/_<layout>.tsx(pathless layout routes) - API routes:
src/routes/api/<name>.ts
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tanstack-start is a skill published in the GitHub repository dlupiak/claude-session-dashboard (76 stars, last pushed 3d ago), licensed MIT. It adds 23 tokens to every session and 293 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
