teams.sgit.ai — roles are boundaries

Roles are boundaries. The Conductor never does the work. The reference for setting up agentic teams with more than one role — not what each role can do, but how nineteen of them are composed into a team that hands work off instead of one generalist doing everything nine times.

Measured from Dinis Cruz's ↗ own product team, SG/Send: 39 ROLE.md files, 19 unique role names, four team instantiations, 130 comms files and 4,335 commits searched — 7 September 2026.

What exists, measured

Every number here is computed from data/roster.json↗ on every build, not typed. 19 unique role names across four team instantiations. 6 carry a falsifiable central claim — the recommended, older form. 7 carry a descriptive claim — true, but not checkable. 6 have no Core Mission or Central Claim recorded and are published as gaps. 6 form the portable core — reached for twice, independently, when the estate stood up a second product.

The finding

Explorer, Villager and Town Planner are the same role names, staffed with different mandates — Wardley's Pioneers–Settlers–Town Planners, implemented as agent configurations rather than drawn as a diagram. As far as the commissioning pack can determine, nobody else has published this.

• Explorer — build the new thing. 17 role directories, 13 defined. The governing rule is discover. The topologies → ↗
• Villager — harden what exists. 17 directories, 17 defined — the only complete team. "Harden, do not build." If a redesign is needed, send it back to Explorer.
• Town Planner — industrialise and capitalise. 4 directories, 3 defined — a sketch, not a template. Financial models wrapped in investor narrative.

What makes it a team, not one agent nine times

An LLM given a task will attempt it. Capability is not the constraint — willingness is — and two fields in the format are what convert a capable generalist into a specialist that hands off.

• Not Responsible For — 31 of 39 files. The explicit exclusion list. A role without one is not a role. The format, in full → ↗
• The Central Claim, as a failure condition — 6 of 39 files. "If a piece of knowledge exists in this repo but cannot be found in under 30 seconds, the Librarian has failed." Checkable. The newer table format lost this. The drift, quantified → ↗
• Addresses, not messages — 130 comms files. A role's definition names the directories it reads and writes, so a new occupant knows its inbox and outbox without being told. The comms protocol → ↗

What this site does not smooth over

A memory site that edits its own past teaches agents to do the same — so the honest parts are published as content, not footnotes.

• A regression. Six older roles state their claim as a falsifiable failure. Seven newer ones state it descriptively — true, but not checkable. The migration improved the markup and lost the property that made the field valuable.
• Six roles carry no recorded Core Mission or Central Claim. advocate, alchemist, ambassador and sherpa have an empty directory in Explorer; accountant and translator are marked defined elsewhere with no identity fields extracted from that file. Town Planner's librarian directory is a fifth, separate empty case. Published as gaps, never filled in for this website. See where they exist → ↗
• Learnings recovered from diffs, not files. A ROLE.md shows what a role is today. The history shows what went wrong badly enough that someone wrote a rule into it. Three learnings → ↗

Build one

Everything above is reference. The assembly guide ↗ is the deliverable: which six roles to start with, what each exclusion list must say, where the comms tree goes, and when to split into Explorer and Villager. Or read the source pack first ↗.
