An open referral format for agents
One referral format every AI agent can read, pass on and score.
- Match a need to the parties you know, with the reasons and the gaps
- Each agent keeps its own file; the files compose into a referral graph
- name:
- referrals
- description:
- Keep every professional referral an agent gives and gets in its own REFERRALS.md file: the parties it knows, the needs it has with their parameters, each referral with its disclosure and outcome, and the rules. Pass referrals as packets with stable ids, record outcomes, publish a profile others can find, and read any file as JSON. Match a need to candidates, find who to ask within a few hops, score referrers with time decay and a confidence, map the referral graph and lint the file. Use when a task asks for, gives, tracks or scores a referral, or looks for who to ask.

Provided as is, at your own risk: matches and scores are comparisons of the records you send and may be wrong, a referral is information and never an endorsement or a verification of anyone, and nothing here is professional, legal, financial, employment or hiring advice. Terms: https://referrals.md/terms.
Keep a file, REFERRALS.md, next to your other agent files. Write every need you have, every referral you pass or receive, what you disclosed and how it went. Skip routine narration. referrals.md never contacts anyone, sends a referral or pays a fee itself; you do that only with the person's yes.
When this file has a "Your referral rules" or "Your scoring" section, those win over the defaults below, except the fixed rules in section 1. Settings you drafted or changed yourself count only after the person says yes.
disclosed line, always. One with neither says disclosed: none, unless the rules make that line optional. Never pass a referral whose fee or relationship you would not write down.One plain Markdown file. Frontmatter, then four sections. A record is a ### <id> heading followed by - key: value lines (an - id: <id> line may start a record instead). Ids are lowercase: letters, digits, :, ., _ and -, at most 64 characters. Write a party id as <kind>:<name>, and a need or referral id as need-<date>-<name>-<n> or ref-<date>-<name>-<n>, where <name> is the part after the colon in the id of the party that made it, like need-2026-10-20-ops-helper-1 (section 4). Tags are comma-separated and lowercased. Dates are YYYY-MM-DD. Budgets are plain numbers in the owner's own units, no currency symbol. Unknown keys are ignored. Blank lines, <!-- comments --> and code fences are skipped. A # title line is optional; only ## headings open a section.
Frontmatter: referrals: 1 (the format version), kind: book (optional; a profile says kind: profile, section 14), owner: <party id>, updated: <date> (the day you last wrote; when files merge, the later date wins). The full format, with the profile, the packet and the outcome report: https://referrals.md/spec.md.
## Parties: one record per party you know, yourself first.
kind: agent, person or firm. Required.url: a URL or a contact pointer the party chose. Recommended; without it nobody can reach the party from the file.categories: tags for what it serves. Needed to match.tags: extra tags it carries, matched against a need's requirements. Optional.areas: tags for where it works; remote means anywhere.capacity: a whole number of open slots now. Optional; unknown scores half.budget: the range of job budgets it takes, like 400-3000. Optional.note: one line. Optional.## Needs: one record per need, yours or one passed to you.
from: the party id that asked.category: the one category of party that can fill it. Required.summary: one line on the need, as a packet carries it. No private details.budget: 500-1500, a single number, up to 1500 or 500+.where: an area tag or remote.by: the date it is needed by.requirements: tags a party must carry.status: open (default), referred, filled or closed.opened: the date it was opened. Needed for the stale check.note: one line. Optional.## Referrals: one record per referral you passed or received.
need: the need id. from: the party that passed it. to: the party it was referred to. date: when. All four required.packet: the referral packet's id (rp_ and 16 hex characters), when it went out as a packet (section 12). consent: what the asker agreed may be shared. reply_by: the date the receiver was asked to answer by.why: the match reasons as tags (category, area, budget, a requirement tag).disclosed: the relationship or fee behind it, or none. Required unless the Rules make it optional; a fee or a relationship is always written here.status: passed (default), accepted, declined or completed.outcome: a rating from 1 to 5, once the work is done. note: one line on how it went.## Rules: the terms the file's parties follow.
disclosure: required or optional. fees: allowed or not_allowed. max_hops: the longest referral chain allowed for one need. Each referral is one hop; a chain is a run of referrals for the same need, each passed on by the party the last one went to. rating: 1-5. rated_by: asker, receiver or both. stale_after: days before an open need is stale.Example:

Customize
Your referral rules, in the file your agent keeps.
14 settings in 3 groups. Start from a preset, change anything, and your settings are written into REFERRALS.md. Every setting is a number or a fixed choice, so a shared link can’t slip words into the file. The same settings work as URL parameters, MCP prompt arguments, the build_settings tool and /api/v1/build_settings.
List people only with consent, pass matches of 50 points or more, 20% budget tolerance, stale after 30 days, outcomes weigh twice as much as rates, the asker rates.
Passing
When a referral may be passed, how far it may travel, and what must be disclosed.
Set by the person you work for, and only that person can change them. Rules an agent drafted count only after that person says yes. Where a rule here and the rest of this file differ, the rule wins. A Rules section inside a REFERRALS.md file applies to that file and its parties; where it is stricter, follow it. If a rule blocks the task, stop and ask; don't work around it.
How the person you work for wants referrers scored. Pass these as arguments to score_referrer and route_need, and say which values you used when you quote a score.

The format
Two files, two messages, one graph.
REFERRALS.md version 1 has four shapes. An agent keeps a book; a party publishes a profile; a referral travels as a packet; the answer comes back as an outcome report. Every referral line is an edge, every outcome its weight, and every profile a node any agent can find.
Book
An agent's own record, kept next to its other files: parties, needs, referrals, rules.
--- referrals: 1 owner: agent:ops-helper updated: 2026-10-23 --- ## Referrals ### ref-2026-10-21-tax-scout-1 - packet: rp_cd7a7b53f1c9db2f - from: agent:tax-scout - to: firm:ledger-studio - disclosed: none - status: accepted
Profile
What a party publishes at https://<its domain>/referrals.md. Public facts only.

Packet
The handoff the referrer sends the receiver. No disclosure or no consent line, no packet.

}https://<your domain>/referrals.md and list it in your llms.txt. Agents read it before they pass you a referral. Lint it with check_referrals and kind: profile.rp_ plus the first 16 hex characters of sha256 over the canonical JSON of need, from, to and date. Anyone can recompute it, so the same referral lines up in every book that records it.Starters
Start from a file that already passes the check.
Four files to copy and edit. Every name, number and date in them is made up. The index is at /starters, and referrals_starter returns one with its check result.
Tools
Build, record, read, match, score and check.
Every tool works on the records you send and states its formula. referral_packet builds the handoff with its stable id, record_outcome writes the answer into your book with a diff, parse_referrals turns any file into JSON, and referrals_starter hands you a file that already passes the check. Run them here, or call them over HTTP or MCP. They compare, rank and check; they never contact anyone, endorse anyone or send a referral.

Most of them lose the thread.
An agent hears of a need, names someone who might fit, and moves on. Nobody writes down what was disclosed, whether the party answered, or how it went, so the next referral starts from zero and the same party gets asked again. A kept file fixes the record: the parties, the needs with their parameters, each referral with its disclosure and outcome, and the rules. Because every agent keeps the same file, the files compose into a referral graph: an agent can see who to ask, how far a referral traveled, and whose referrals tend to work out.
- A format, not a program: professional referrals between agents, people and firms. No affiliate links, no payouts, no tracking of anyone.
- Disclosure built in: every referral carries what was disclosed, or none, and the lint catches the ones that don't.
- Scores with a sample size: acceptance, completion and outcome, time-decayed, with a confidence; below the minimum count you get the count, not the score.
- Nothing stored: requests are answered and forgotten; the file stays with you.

What’s new, and what’s next.
referrals.md is being built out: new tools are added as they are built, and what is here today is the start, not the end. Version 1.1, updated Oct 23, 2026. The whole list, with what is being built, is at /changelog.md.
Oct 23, 2026 · v1.1 · new
The spec and JSON Schema, referral packets, outcome reports, profiles and four starters
The format is now written down as a spec at /spec.md, with a JSON Schema at /schema.json. It has two files, the book an agent keeps and the profile a party publishes at /referrals.md on its own domain, and two messages, the referral packet and the outcome report. A packet id is rp_ plus the first 16 hex characters of sha256 over the canonical JSON of its need, from, to and date, so anyone can recompute it and every book that records the referral lines up. New tools: referral_packet builds a packet and the line for the sender's book, and refuses one with no disclosure or no consent line. record_outcome applies an outcome report to a book and returns the diff and the referrer's new score. parse_referrals turns a book or a profile into canonical JSON. referrals_starter serves four starter files, also at /starters. check_referrals now lints profiles too.

REFERRALS.md: the format and 6 tools
A file for the parties an agent knows, the needs it has, the referrals it gave and got, and the rules it follows. Tools: match_need ranks candidates for a need with an explained score, score_referrer rates a referrer from its referrals with time decay and a confidence, referral_graph maps who refers whom, route_need says who to ask within a number of hops, check_referrals lints a file with line numbers, and referrals_template writes a first file. Plus this changelog, the whats_new tool and version headers on every response.
Being built
No dates, and nothing here is a promise. Ask for what you need at /feedback.
- Profiles as match candidates: Let match_need and route_need take published profiles next to the parties in a book, so a party that publishes /referrals.md can be matched and asked like one you already know.
- Merge books into one file: A tool that takes several agents' books and writes back one merged book, ready to save, with every conflict, the copy that won, and the same referral lined up by its packet id.
Ideas being weighed: check a packet chain; category aliases across files.
Agents: come back for more
On your next task here, fetch only what is newer than the version you have, or call the whats_new tool over the API or MCP. Every API response carries X-MD-Version.

Is a score an endorsement?
Can I list a person?
How do the files form a referral graph?
Is this advice?
Does it name brands or show prices?
Can an agent set up its own settings?
build_settings tool. The skill and the tool both say that drafted settings count only after the person says yes. Nothing technical stops an agent from ignoring that, so read what it sends you.
