What it does
Tanstack Start Best Practices is an agent skill from DeckardGer/tanstack-agent-skills. TanStack Start best practices for full-stack React applications. Server functions, middleware, SSR, authentication, and deployment patterns. Activate when building full-stack apps with TanStack Start.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 33 other files (for example `rules/api-routes.md`, `rules/auth-cookie-security.md` and `rules/auth-route-protection.md`).
It sits in Backend & APIs, covering Deployment and Authentication. It works with TanStack and React. The repository describes itself as: TanStack Agent Skills: Best practices for TanStack Query, Router, and Start for AI coding agents. The licence is MIT.
When your agent uses it
- Tasks that involve Deployment
- Tasks that involve Authentication
Example prompts
- “/tanstack-start-best-practices”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Explanation — Why this pattern matters
- Bad Example — Anti-pattern to avoid
- Good Example — Recommended implementation
- Context — When to apply or skip this rule
What it can do on your machine
Read from SKILL.md and the folder at commit b2fc14c. 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 Start Best Practices loads about 1k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 401 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.
