database-lookup

database-lookup is a skill for Claude Code from agentlas-ai/agentlas-desktop. It costs 50 tokens per session (6,713 once invoked), scanned B, a copy of database-lookup, Apache-2.0.

A method for retrieving facts from documented public databases through their official APIs, or programmatic access points. It selects a suitable source, applies explicit filters and pagination, and records enough source information for the lookup to be repeated.

In plain words
What is it for?
Use it to retrieve bounded or exhaustive records from scientific, regulatory, financial, and other public databases, resolve identifiers, verify counts, and return provenance for the results.
Why use it?
It reduces errors from incomplete searches, unclear filters, or unsupported guesses. It is useful when the result must be traceable to a named database and reproducible by someone else.

Token cost

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.

Security

Grade B, and why

database-lookup scanned grade B with 2 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

These databases require HTTP POST and **will not work with WebFetch** (GET-only). Use `curl` via your platform's shell tool instead:

Database Lookup

This skill catalogs 80 public databases with documented API access patterns. Your job is to turn the user's intent into a reproducible retrieval: select the authoritative database(s), make bounded and rate-limited API calls, verify counts when completeness matters, and return results with enough provenance that another agent or human can repeat the lookup.

For complex biomedical retrievals, assume small filtering differences can change downstream conclusions. Prefer deterministic APIs, explicit identifiers, exhaustive pagination, and auditable logs over broad searching or plausible summaries.

Core Workflow

  1. Define the retrieval contract — Identify the target entity, accepted identifiers, organism/taxon/build/date constraints, filters, expected output fields, and whether the user needs an exhaustive dataset or a targeted lookup. If a required scientific constraint is missing and affects correctness, ask a clarifying question rather than guessing.

  2. Select authoritative database(s) — Use the database selection guide below. Prefer the primary database for the user's intent, then add cross-check databases only for identifier resolution, validation, or known coverage gaps. Do not fan out across many APIs just because they are available.

  3. Read the reference file and retrieval contract — Each database has a reference file in references/ with endpoint details, query formats, and example calls. Read the relevant file(s) and references/retrieval-contract.md before making API calls.

  4. Plan filter semantics before calling — Separate filters the API enforces server-side from filters that must be checked locally. Note identifier conversions, fields with ambiguous meanings, pagination strategy, rate limits, and any data-source conventions such as RefSeq vs GenBank or genome build.

  5. Make bounded API calls — See the Making API Calls section below. For exhaustive retrievals, count first when the API supports it, estimate cost, paginate or batch until retrieved counts reconcile, and fail visibly if the final dataset is incomplete. Ask for confirmation before a retrieval would exceed 10,000 records, 100 API calls, or the selected API's documented bulk-use guidance.

database-lookup is a skill published in the GitHub repository agentlas-ai/agentlas-desktop (6 stars, last pushed today), licensed Apache-2.0. It adds 50 tokens to every session and 6,713 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). It is 94% identical to database-lookup, differing in 88 lines, and is treated as a copy.
