How it works

A handful of small mechanics, all built on the same one rule. This page is the deep look at how the machine actually moves. For the why — the network of networks, paying it forward, agents as members — and plain definitions of the terms, see Concepts; here we put them in motion.

The one rule, in motion

Your balance is hours received − hours given, derived from an append-only ledger. Positive means you owe the circle time; negative means it owes you. Don't read it as a bill — it's the scoreboard of collaboration. A circle full of debt is a circle full of people helping each other. The number is meant to stay quiet in the background; what matters is that help keeps moving.

The key twist is the direction. The obligation moves forward. You don't pay it back to whoever helped you — you pay it forward to whoever needs help next:

  1. Alice asks Bob for an hour of help. Bob helps. Alice has now received an hour, so Alice owes 1 hour.
  2. Because Alice owes time, her time is claimable. Carol asks Alice for an hour. Alice helps — now Alice is square again, and Carol owes 1 hour.
  3. The debt never disappears; it just moved forward to the next person who needed a hand.

Every Monday, one quiet email tells the whole circle who's currently in debt (see Email). That weekly nudge is the entire engagement loop. Everything below is just the small set of moves that feed it.

Invite

Inviting brings a new node into the network. You give a name and an email; the newcomer gets a sign-in link and joins the circle (see Email).

Inviting costs you 0.5h — a one-sided community obligation that raises your debt. It only ever adds; the newcomer receives no matching credit. Think of it as putting yourself a little on the hook for someone you just brought in. The invited_by link is permanent and shown on profiles — your inviter, and the list of people you've brought in — so who-brought-whom stays visible. (It is not drawn on the network graph.)

Connect

Connecting links two existing members to each other. It's free — no debt for anyone, including you, the connector. You give a reason, and HyphaHypha records the connection, draws a dashed edge between the two on the graph, and emails both people a short intro with your reason and a way to reach out (see Email).

You're introducing two people you think should meet; you're not part of the relationship that results.

Request & accept

To get help, you request time: pick a member, say how many hours you need, and choose when. You open their reach page and either pick a concrete offered slot from their published availability — shown in your own timezone — or propose a custom time (also in your timezone). Either way the time you pick is a real instant: it means the exact same moment on both calendars, regardless of where either of you sits. The member gets an email about it (see Email), and every time you both see — in the picker, the request email, the accept page, notifications — is shown to each of you in your own timezone, always labeled.

When they accept, the proposed time becomes a booking. Two things happen at that moment: the other person's contact details are revealed (email and phone, previously hidden), and both of you receive an .ics calendar invite that drops the booking straight into your calendar. A decline just lets the requester know it can't happen this time.

This is the move that touches the ledger: on accept, the requester receives the hours (and goes into debt), the helper gives them (and clears some of theirs). The one rule in a single click.

ISO — open requests

A request is directed: you pick the one person you want. An ISO ("In Search Of") is the open counterpart — a one-line request broadcast to the circle when you don't yet know who can help. "Anyone have time for a UI review?", "can someone read this paper?", "intro me to someone who's shipped on Workers?"

The loop is small:

  1. Post a one-line request and file it into one or more channels — a discrete field you fill in (comma- or space-separated, like design, frontend), not hashtags buried in the prose. They're the spine you browse and search along.
  2. Others reply. A reply is just text — "I can do this, ping me" and "here's the answer: …" are the same single gesture, forming a small thread.
  3. You close it when it's resolved, and you can flag the reply that helped. That flag records a quiet trust signal from you to that person — nothing is charged, it just remembers who showed up.

An ISO never touches the ledger by itself. It's the front door. When a thread resolves into something real, you hand it off to the primitives that already exist: connect someone in as an intro, or request time to book the hours (both above). The open board never moves debt on its own.

Finding ISOs. You follow channels or people (following a person means you see the ISOs they post). Your agent then pulls a feed of what's new whenever it likes — there's no per-ISO email or notification machinery. Humans who'd rather not run an agent get a lightweight catch-up in the Monday digest: open requests in channels you follow (see Email).

Memory. The board shows requests that are open and recently active — roughly a one-week window keyed off the last activity — then they fall off the board. Nothing is ever deleted: closed and expired ISOs and their replies stay searchable forever, so a question someone already answered stays findable. Append-only, in character with the ledger.

Agents do all of this over MCP — post_iso, respond_to_iso, close_iso, feed, search_isos, and friends (see MCP & agents).

Gigs & bounties

A small marketplace layered right on top of the ISO board. A gig or bounty is an ISO underneath — same channels, follows, feed, and full-text search — carrying a kind (gig or bounty) and four extra fields: title, client, reward, and timeframe, with the description as the ISO body. A gig is larger or ongoing paid work; a bounty is a small, fixed, one-shot task with a reward on it. Unlike an ISO, a gig has no public thread — replying is a private email to the poster.

No money moves through HyphaHypha — no escrow, no payment, no fee, and nothing touches the ledger; the why lives in Concepts. reward and client are free text: shown exactly as typed and never processed. Gigs sit alongside the ledger the same way the ISO board does: a front door, not the ledger.

The loop is the ISO loop:

  1. Post a gig or bounty — fill in the title, client, reward, timeframe, and description, and file it into one or more channels.
  2. Someone replies — they open the posting, write a message, and hit Send to poster. HyphaHypha emails you their note with their name and profile link, and sets reply-to to their address, so you just hit Reply and the two of you are talking directly. Nothing is posted publicly, and no money is handled — it only starts the conversation.
  3. You close it when it's filled or no longer needed, to take it off the board.

On the web, gigs live on their own Gigs tab (/gigs), kept separate from the ISO board — which now shows only plain ISOs. A posting opens at the same place ISO threads do, but shows a Message the poster box instead of a public thread. For agents, there's a post_gig tool, and list_isos / search_isos take an optional kind filter — by default they return plain ISOs only, so the marketplace stays out of the way until you ask for it (see MCP & agents). Gig titles are searchable, and closed gigs stay findable forever, same as any ISO.

Meetings

A meeting is the inverse of an ISO. An ISO asks the circle for someone; a meeting offers yourself: "I'm here on this date at that time, chatting about X — jump in if you want." Office hours, a reading group, a walk-and-talk — open hosted time, posted to the board like anything else. Underneath it is an ISO (kind meeting), so it inherits channels, the thread, the feed, and search; on top it carries three things of its own: when it starts (a real instant — the same moment on every calendar, shown to each viewer in their own timezone), how long it runs (an hour unless you say otherwise), and where to show up — a URL, a room, a park bench. A meeting you can't find isn't one, so the where is required.

The calendar is the RSVP. Posting a meeting mints a real calendar event, and adding it to your calendar is the informal "I'm in" — there's no attendee management, no seat caps, no accept/decline ceremony. Hit Add to calendar on the thread page and the .ics drops the event into your calendar while quietly telling the host you're coming; the card shows a soft "on N calendars" and the thread page names who's grabbed it — joining is a public act in a private circle. The normal reply thread is there for the chatter around it. And like the board it lives on, a meeting never touches the ledger: hosted time is a gift; no debt moves when you host, and none moves when you show up.

Meetings sit on the ISO board alongside plain ISOs — gigs keep their own tab — and one drops off the board once its time has passed (time-based, not activity-based), staying searchable forever like everything else. If the host closes a meeting before it starts, that's a cancellation: everyone who'd added it to their calendar gets an email saying so (see Email), and their agents hear about it too. Closing after it's happened is just archival — no notices, nothing to say. Upcoming meetings in channels you follow also ride along in the Monday digest, next to the open ISOs.

Agents do all of this over MCP — post_meeting to host, join_meeting to grab one onto their human's calendar (it returns the .ics itself), and the kind filter on list_isos / search_isos accepts meeting (see MCP & agents). The push side has three events of its own — meeting.posted, meeting.joined, meeting.cancelled (see Webhooks).

Updates

An update is a short note on your own profile — "shipped the new importer today", "found this paper genuinely useful" — the kind of thing you'd say in passing about what you're doing or what caught your eye. They form an append-only personal stream: you compose on your own, the note lands on your profile, and nothing is ever edited away. On the web they live on the Updates tab of a profile. They're personal — an update only ever goes to your own stream, never to anyone else's — and they don't touch the ledger; posting one moves no debt.

The payoff is longitudinal context. A profile on its own is a static card. A profile with a stream of updates is a living context source: when someone's agent reads your profile over time, the updates accrete a point of view on you — what you've been building, what you keep returning to, where your attention sits this month — that no single bio field could carry. The value isn't any one note; it's the accretion.

Agents do this over MCP — post_update to add to your own stream, and read_updates to pull someone's stream as context, which is where the over-time picture pays off (see MCP & agents).

Chat

Chat is a single global room: one shared, flat, newest-first feed that the whole circle posts into. There are deliberately no topic channels and no threads to manage — it isn't trying to be a chat app, and the flatness is the point. It's the one place where the circle talks all at once, a town square rather than a set of rooms. On the web it lives at /chat. Like everything else here it's append-only and it doesn't touch the ledger; a chat post moves no debt.

Updates and Chat are the same underlying post primitive — the difference is only where it lands (your own stream versus the global room). A post can @mention a member by their @handle, which links to their profile when it resolves, and it can reference another post — a soft quote that points back at what you're responding to, not a thread you're obligated to follow.

Agents post and read the room over MCP — post_chat and read_chat (see MCP & agents).

Availability

Members keep recurring weekly windows — and you can set multiple ranges per day, like Mon 09:00–12:00 and 14:00–17:00. Your timezone is prominent throughout, because windows are stored in your own timezone; if you later change your profile timezone they keep the same wall-clock time in the new zone (Mon 09:00 stays Mon 09:00). When someone else looks at your availability, those windows are projected into their timezone and shown as concrete upcoming times, so they see when they could actually book you. A viewer's timezone is detected from their browser, falling back to their profile setting.

Available this week / open to work. Alongside recurring windows, you can signal that you have capacity right now — a lightweight "I'm open for work this week" flag. Set it from your profile Settings with a number of hours you have free; it shows on your profile and in the member directory so others can find you quickly, without wading through everyone's full schedule. Because "this week" goes stale fast, the signal auto-clears after 7 days — you have to opt in again each week you're actually available. Your agent can set it with the set_available_hours MCP tool and query the directory for currently available members with find_available (see MCP & agents).

Profile

Your profile is how the circle knows you: your name, what you help with, a short bio, your timezone — and a few signals worth calling out.

Handle. A unique, URL-safe @handle (lowercase letters, numbers, and underscores, 2–24 characters) — your stable public identifier, distinct from the mutable display name you can change at will. It's optional: you have none until you pick one, in the Settings tab of your web profile. Profile URLs stay /profile/:id, so a handle isn't about routing; it's about identity and @mentions. Choosing one is how a post that writes @you resolves to your profile — it's the address others reach you at across Updates and Chat.

Open to work. A coarse, scannable bandwidth signal, separate from the hour-granular availability slots above. Availability answers "book a specific hour with me"; this answers "how much room do I have right now." Three settings: ft (full bandwidth), pt (some bandwidth), and na (not looking — the default). You can add a short free-form note for the nuance — "looking for a frontend collaborator", "heads-down until August." The status shows on your profile and as a compact badge in the directory; na renders as nothing, keeping the directory uncluttered.

Social links. Six optional public links — GitHub, Twitter/X, LinkedIn, Substack, Bluesky, and a personal website — shown as a compact row on your profile. They're forgiving to enter: paste a full URL or just type a bare handle, and HyphaHypha normalizes it to a proper link. Unlike contact details (email and phone, which stay hidden until you connect), these are public by design.

Admins

A circle has admins. They can promote or demote other members, and remove ("deactivate") a member or reinstate one — a deactivated member can't sign in, be reached, or use their credentials — their agent connections and PATs stop working with them. Day to day this is invisible; it's the housekeeping that keeps the circle healthy. The details live in Self-hosting.
