Crossfeed

Rank by who listens

An agent that ranks your network’s shows by listener overlap in Qloo, asks you at each fork, and ends in an insertion order you approve.

Signs you in as a guest, for a day. Every guest shares the network, which opens on 19 public show names from The Ringer, with sample figures. Crossfeed isn’t affiliated with The Ringer.

What a topic plan misses

A plan by topic puts Low Tide, a true-crime launch, on the network’s crime and courtroom shows. Ranked by who listens, three of its five finalists come from outside that top five.

Launch: Low Tide

A true-crime show set in a fishing town, from Kiln Street Audio, a network of 8 shows.

How a run works

  1. Seconds

    You

    First, you name the launch, or up to three comps for one that isn’t out yet.

  2. About ten seconds

    The agent

    Then the agent ranks the roster by listener overlap with the launch, in Qloo.

  3. Up to you

    You

    Then it stops to ask for the slot budget and the shows to leave out, and waits for your answers.

  4. Under a minute

    The agent

    Then it checks the finalists’ listeners, finds the tags each shares with the launch, and drafts the plan.

  5. Up to you

    You

    Last, you edit the insertion order, approve it, and export it as CSV. Nothing is final until you do.

What it does

Ranks the roster

It looks every show up in Qloo and scores the whole roster against the launch in one call. The on-air readout and the run log say what it’s doing while it works.

Asks at each fork

Where a plan needs a person, it stops and asks rather than guess: the slot budget, the shows to leave out, which match is right when a name is ambiguous. The run waits for the answer.

Answer

Drafts the plan

It drafts an insertion order across the finalists, with a host-read angle for each from the tags it shares with the launch. Code prices every slot from your own downloads and CPM, and nothing is final until you approve it.

The plan

Insertion order IO-0001

Draft

Agent drafted the slots and angles. Code prices each slot at downloads per episode × CPM ÷ 1,000.

Every match, rank, and tag carries the number of the Qloo call behind it. Open one for the request, its parameters, and what Qloo returned. Claude explains and drafts from those records, and never makes up a score.

Triages pitches

Paste a day’s pitches. Claude reads each one for the guest’s public work, Qloo ranks those works against your show by who listens, and the agent drafts a Book, Later, or Decline reply. A reply can be copied only once you approve it.

    Hi Ines, thanks for sending Salt Ledger. Mara’s book is a close fit for The Harbour’s listeners, and we’d like her on for an episode about the cannery strike. Could she record in the first week of March?

    Hi Sam, The Breakwater looks like one for The Harbour: its audience is close to ours. We’d like Tom on to talk about filming the 1953 storm with the town’s boats. Is he free to record this spring?

Works from code

Programs and assistants start runs, relay the agent’s questions, and edit drafts through the REST API, the TypeScript SDK, the MCP server, and Agent Skills. None of them can approve. For developers

What Crossfeed never does

Crossfeed neverInstead
Sends a guest’s name or a pitch to Qloo.Only public shows and works are looked up. A guest with no public work is set aside, and a title holding an email address or the guest’s own name isn’t sent.
Reads a result as a fact about a person.Fit describes overlapping audiences, never a probability about an individual, and nothing infers anyone’s politics, health, or eligibility for anything.
Makes up a score.Every fit ranking is a Qloo call you can open. The model narrates the evidence and drafts from it.
Prices a plan with numbers you didn’t give it.Slot value comes from the downloads and CPM your network enters. There’s no default CPM; the sample network’s is labelled sample.
Approves anything for you.The agent proposes and you decide. An insertion order exports, and a reply can be copied, only after you approve it. Crossfeed sends no email.
Publishes Qloo’s data.Qloo’s responses are cached on Crossfeed’s server and shown only in the app.

For developers

Crossfeed is one Cloudflare Worker. The page is server-rendered, and the workspace talks to its agent over a WebSocket: it reads the agent’s synced state and calls its actions, and never writes state itself.

Programs and assistants can plan a network’s launches and triage its pitches too, with one of its API keys. None of them can approve: that stays with the network’s members, in the app.

  • REST API

    Every resource of a network under /api/v1, described by an OpenAPI document.

  • TypeScript SDK

    Typed methods for every route, for Node, Bun, Deno, and Workers.

  • MCP server

    The same operations as tools, for assistants such as Claude Code.

  • Skills and plugin

    Agent Skills that plan launch promos and triage pitches, in a Claude Code plugin.
