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 | $0.00146 | $0.02763 |
| Opus 5 | $0.00073 | $0.01381 |
| Sonnet 5 | $0.00029 | $0.00553 |
| Haiku 4.5 | $0.00015 | $0.00276 |
Grade A, and why
data-sdk-install 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
reopt Data SDK Install
Read the installed package READMEs before writing integration code. The supported suite is
@reopt-ai/data-sdk-client+@reopt-ai/data-sdk-server;@reopt-ai/data-sdk-devtoolis optional;@reopt-ai/data-cli(binreopt-data, Node 22+) is the build/CI tool for source maps and the event catalogue.@reopt-ai/data-sdkon npm is a deprecated meta-package — never install or import it.
When to apply
Use for first installs, upgrades, and turning on error tracking in an app that already tracks. Default to a complete Next.js App Router integration; route React, vanilla, and Node-only requests to the matching README.
Step 1 — Inspect before changing
- Detect package manager, framework and versions, existing SDK imports, env names,
proxy.ts/middleware.ts, provider/layout, server tracking, consent owner, tenant model, and whether a build step already emits source maps. - Read the installed versions from package manifests. Supported floor: client/server
0.2.0, optional devtool0.2.0, contract0.7.0; verified against client0.4.0, server0.5.0, contract0.10.0, data-cli0.1.0. Keep client and server on the same release when both are installed. A0.1.xclient still ingests, but it lacks the structured$exception_list,captureExceptionoptions, breadcrumbs andrelease— upgrade before wiring error tracking. Server0.5.0dropped itsreopt-databin: apostbuildthat callsinject-chunk-ids/upload-sourcemapsfrom the server package breaks on upgrade until@reopt-ai/data-cliis added as a dev dependency.
Step 2 — Pin agent rules
No Data SDK package ships an agent-rules file as of the versions above. Use this skill's agent-rules.md fallback and place it in AGENTS.md (or CLAUDE.md only when AGENTS is absent) between:
<!-- BEGIN:reopt/data-sdk-agent-rules -->
…fallback content…
<!-- END:reopt/data-sdk-agent-rules -->
Replace only content inside existing markers.
Step 3 — Consumer setup
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

data-sdk-install is a skill published in the GitHub repository reopt-ai/reopt-skills (1 stars, last pushed 5d ago), licensed MIT. It adds 146 tokens to every session and 2,763 once invoked, about $0.0007 per session on Opus 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 2026-08-31.
