Exa Query and Content Policy Guardrails
Overview
Enforce query, domain, moderation, freshness, content, and downstream-use policy before and after Exa retrieval. Treat credentials, queries, retrieved content, generated output, spend, and destructive state as separately governed boundaries.
Prerequisites
- The target repository, environment, Exa team, product surface, and accountable owner.
- The workload's data classification, latency and freshness promise, cost ceiling, and retention policy.
- Current first-party documentation plus credentials only for a narrowly approved live check.
Current Contract
Search supports include and exclude domains, date filters, categories, user location, and moderation, with documented category incompatibilities. These controls reduce scope but do not replace application authorization, content inspection, attribution, or output policy.
Authentication
For normal REST work, inject EXA_API_KEY from an approved server-side secret manager and send it only as Authorization: Bearer to the configured first-party Exa API host. Team Management service keys, hosted MCP OAuth or enterprise managed authorization, and payment-protocol calls are separate trust models. Never print, commit, place in a URL, or expose a credential to an untrusted client.
Instructions
- Translate the business purpose into allowed query classes, domains, dates, and outputs.
- Reject secrets, prohibited personal data, and disallowed investigation intent before retrieval.
- Apply supported Exa filters and moderation without inventing unsupported combinations.
- Inspect returned URLs, content, citations, and generated fields against the same policy.
- Quarantine prompt injection, malware, unverifiable claims, and unexpected sensitive data.
- Log content-free policy decisions and review exceptions with an accountable owner.
Tool Discipline
Use Read, Glob, and Grep to inspect repository code, configuration, fixtures, and evidence. Use Write and Edit only for approved implementation or documentation changes. Do not call Exa, run paid research, create or alter a Monitor, Webset, Agent run, Batch, team, member, API key, budget, webhook, or deployment merely because this skill was invoked.
Approval Boundaries
Require an accountable owner before live queries involving sensitive intent, production credentials, spend or rate-limit changes, forced live crawling, generated summaries, external delivery, deployment, member or key changes, schedule creation, or destructive cancellation, stopping, deletion, or revocation. Read-only repository inspection and synthetic offline validation do not authorize live vendor actions.
Failure Modes
- Domain allowlists do not guarantee that every page is safe or accurate.
- Company and people categories do not support every date or exclusion filter.
- Moderation is not a substitute for tenant authorization or legal review.
Output
Return the operation scope, environment, team and product surface, authorization class, contract and policy decisions, deterministic validation results, content-free identifiers, status and cost counts, risks, cleanup or rollback state, and a concise pass or fail receipt. Exclude credentials, raw queries, prompts, presigned URLs, retrieved content, generated output, and customer-derived data unless separately approved.
Example
- Permit a news query only on approved domains and dates, enable moderation, then re-check every returned URL before downstream use.
- Finish with request or resource IDs, assertion counts, cost and terminal state, rollback or deletion status, and the decision owner; never reproduce secrets or retrieved content.
Validation
Rerun the smallest relevant deterministic test, compare actual behavior with the requested outcome and current first-party contract, verify sensitive fields are absent from evidence, and confirm deadlines, terminal state, downstream retention, and rollback before reporting success.
