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 | $0.00110 | $0.02579 |
| Opus 5 | $0.00055 | $0.01290 |
| Sonnet 5 | $0.00022 | $0.00516 |
| Haiku 4.5 | $0.00011 | $0.00258 |
Grade A, and why
chainlink-data-streams-skill 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 6d 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.

Chainlink Data Streams Skill
Overview
Route Data Streams requests to the simplest valid path while keeping side effects and credential exposure out of the agent runtime.
Progressive Disclosure
- Keep this file as the default guide.
- Read references/credentials-and-auth.md only when the user asks how to get Data Streams credentials, how authentication works, how to configure API keys, or how to debug auth failures.
- Read references/report-schemas.md only when the user asks about report schema versions, schema fields, deprecated or available schemas, report decoding, or how to choose the correct decoder.
- Read references/rest-sdk.md only when the user wants Go, Rust, or TypeScript code to fetch reports through REST, including latest reports, timestamp lookups, bulk lookups, or paginated history.
- Read references/websocket-sdk.md only when the user wants Go, Rust, or TypeScript code to stream reports through WebSockets, with or without High Availability mode.
- Read references/onchain-verification.md only when the user wants EVM, Solana, or Stellar code that verifies Data Streams reports onchain, wants Chainlink Local mock testing for Data Streams verification, or wants review/debugging of verification code.
- Read references/frontend-and-storage.md only when the user wants a real-time frontend, candlestick display, local SQLite persistence, or local report history tracking.
- Read references/public-endpoints-and-addresses.md only when the user needs public REST/WebSocket/candlestick endpoint defaults, supported-network verifier proxy/program IDs, or an offline fallback for those public details.
- Read references/official-sources.md only when the answer depends on live Data Streams facts: current endpoint behavior, feed IDs, schema availability, deprecation status, SDK package versions, verifier addresses, supported networks, or current docs.
- Do not load reference files speculatively.

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.

chainlink-data-streams-skill is a skill published in the GitHub repository smartcontractkit/chainlink-agent-skills (125 stars, last pushed yesterday), licensed MIT. It adds 110 tokens to every session and 2,579 once invoked, about $0.0006 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 2026-08-30.
