worked on a set of agent skills to help my clankers build better cli/tui tools

Agents on JarvisCore now act with each person's own account, not a shared service key.
The first time Erin's work needs Claims Hub, she's asked to connect hers. The work picks up where it stopped, and Claims Hub sees every call as Erin. ↓
Credentials are brokered by Nexus (open source) and released only for the person they belong to. It works with your in-house systems too.

Today, we're open-sourcing JarvisCore Agents: blueprints for building teams of agents on JarvisCore.
Five complete agent systems for real domains, each with its tests, a demo you can run offline, and the Desk to run and watch it.
Available today ↓

Each blueprint is a few files of ordinary JarvisCore: agents, their prompts and contracts, and a team.py that builds the Mesh. No orchestrator agent, no framework code copied in.
Fork it, run the offline demos, then copy the shape for your own domain.

What's in it:
- Claims: an insurer's claims desk, held to the organisation's own scopes
- Multiplayer: a team and its agents in one room
- Software Reliability: find, reproduce and fix a real defect
- GTM: a go-to-market desk
- Personal Intelligence: one agent for one person

build amazing agents with JarvisCore!
added 2 more CustomAgents to my swe persona
one of them just watches the execution of other agents in that Mesh. if something breaks, it triages, builds a fix if need be, tests, and deploys the fix to the affected agent(s)
i’m running these JarvisCore agents on my old linux laptop btw. the short downtime was just a network drop

Your agents can now carry your organisation's own scopes.
Erin can't approve claims. Carol can, up to £10,000. JarvisCore holds every call an agent makes for them to that, before it reaches your system.
Same agent, same tools. Different person, different answer. ↓
jarviscore policy scopes shows who may do what.

i built a cool code-review persona for my personal projects with jarviscore.developers.presco…
it's a team of 6 autonomous agents that wake up when you mention the persona on a GitHub PR.
the agents read the diff, run your test suite in a sandbox, post inline review comments, and propose fixes they only push once you reply "apply"
Introducing multiplayer agents in JarvisCore 2.3!
Your team and its agents, in the same thread. Anyone asks in their own words, the work comes back as a proposal, and only the person who decides gets the Confirm button.
pip install -U jarviscore-framework

Bring it to where your team already talks. Slack works out of the box, or connect a room to your own product's chat.
Work runs on the JarvisCore mesh, so it carries on if a process stops.

The agents work as the person who asked: their connected accounts, their access.
Work that used someone's private access is held for them first, and only reaches the room when they release it.

Real teams talk over each other. When two people push back at the same moment, JarvisCore starts one revision, not two.
Anything added while work is running is kept and applied to its result. Nothing anyone asked for is lost, and only one version lands.

A room is shared files plus the people allowed to touch them: owners, editors, viewers.
Every change the agents make is a proposal you can read as a diff, preview, accept or turn down. Nothing lands until a person confirms it.

Most multi-agent systems route every message through one orchestrator. When it goes down, everything stops.
Join @MutuaDevOps this Thursday for a live build-along: agents that find each other and talk directly, built on JarvisCore.
