Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00041 | $0.00382 |
| Opus 5.5 | $0.00016 | $0.00153 |
| Sonnet 5.5 | $0.00008 | $0.00076 |
| Haiku 4.5 | $0.00004 | $0.00038 |
Grade A, and why
tanstack-versioned-skills 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 today.
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
Load guidance shipped with the installed TanStack library before changing its behavior.
- Read package manifests and lockfiles to identify TanStack packages, exact versions, and the package manager. Distinguish the installed version from the manifest range.
- Locate relevant skills in the installed package and its metadata. Use the project's existing Intent list and load commands when available. Read the selected SKILL.md and only the references needed for the task.
- If Intent is unavailable, read the package-owned skill files directly. Do not invoke floating npx @tanstack/intent@latest or install a dependency solely to locate instructions.
- If a package is not installed, establish the locked or explicitly selected version before obtaining its guidance. If no packaged skill exists, use that version's documentation. Do not substitute the latest release's instructions. Missing skills do not block a verifiable documentation-based fix.
- For Query, inspect query keys, freshness, retention, invalidation, and optimistic rollback. For Router or Start, inspect parameters, loaders, client/server boundaries, SSR, and state transfer. Load only the profile relevant to the change.
- Preserve the framework, package version, and existing configuration. Do not install hooks, edit gates, or managed AGENTS.md blocks. Load applicable skills using the host's ordinary file-reading capabilities.
- Verify types, builds, and the affected data path. Where SSR or mutations change, verify failure, navigation, and repeat-request behavior.
Check exact discovery and command semantics against TanStack Intent and the chosen library's documentation. Guidance must match the package version.
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-versioned-skills is a skill published in the GitHub repository dayfinggg/openai-codex-agent-skills (8 stars, last pushed today), licensed MIT. It adds 41 tokens to every session and 382 once invoked, about $0.0002 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 2026-10-30.
