# Replace a client's assignment rules

Replace-all upsert of the client's assignment rules. Each rule binds an integration to the client via \*\*either\*\* a raw \`filterCriteria\` object \*\*or\*\*, for Slack, the \`slackChannels\` shorthand — a list of channel names the server expands into the equivalent criteria, so you never have to hand-build the query structure. The two are mutually exclusive, and \`slackChannels\` is only valid on a Slack integration. Replace semantics: any integration \*\*omitted\*\* from \`rules\` has its existing rule removed. Send an empty \`rules\` array to clear every rule. A save re-applies the rules to the client's existing conversations (see \`reapplyStats\`) and can start a Slack history backfill. Use a GET-then-PUT flow to avoid unintentionally wiping rules you didn't mean to touch. Cross-tenant clients and integrations return \`404 not_found\` / \`400 invalid_argument\` with no existence leak.

# Agent Instructions

This portal answers questions programmatically. To receive a synthesized,
source-cited answer instead of crawling page by page, append the `?ask=`
query parameter to any page URL on this site:

    /guides/quickstart?ask=how+do+I+authenticate

Optional parameters:

- `&goal=<what-you-are-trying-to-do>` steers the answer toward your
  objective (e.g. `&goal=write+a+python+client`).
- `&version=<label>` scopes the answer to a mounted version when the
  portal publishes more than one.

The response is `text/markdown`: the answer followed by a `# Sources` list
of the portal pages it was grounded in. Status codes are the contract:

- `200` — the answer; `402` — the portal owner’s plan or answer credits are
  exhausted (surface this to your operator; do NOT retry); `429` — you are
  rate-limited; back off for the `Retry-After` seconds; `503` — the answer
  lane is temporarily unavailable; fall back to crawling the `.md` pages.

For the full corpus map read `llms.txt` at the site root; for the tool
surface (search + page fetch as MCP tools) see `/mcp`.
