Speckit and Multi Agent Orchestration

[vessel-one]

Hi everyone,

Is anyone else experimenting with multi-agent workflows using GitHub Copilot, SpecKit, and VS Code?

I’ve been getting decent results so far — mainly by leveraging SpecKit for structure up until the task stage. Before implementation, I ask Sonnet 4.5 to enable multi-agent workflows through chat. It then rebuilds the tasks, assigns each to specific agents, and generates an agent-coordination.json file that defines priorities, parallel and blocking tasks — ensuring agents don’t overlap or start prematurely.

From there, I open several chat windows and use the prompts Sonnet 4.5 provides for each agent. Haiku 4.5 handles execution, and the results have been surprisingly good. Once the other agents finish, I get Sonnet 4.5 to review their output and provide the next set of instructions. It feels like this process could be integrated directly into SpecKit with a /command for smoother coordination.

With all the hype (and skepticism) around AI right now, we’re actually seeing strong, measurable results from SpecKit. We only implement small, incremental features at a time and slightly adjust the development flow — asking it to build tests, build feature tests, repair, build, test, repair rather than leaving testing until the end. This approach seems to catch about 98 % of errors, leaving only minor bugs.

Overall, results have been solid once you understand its limits — but I’m curious how others are approaching this.

Hey @vessel-one, thanks for sharing! Im experimenting with SpecKit, was wondering where do you fit the testing phase? Do you include it when you run the plan command?

@vessel-one Have you considered adding extensions or presets so others can benefit from it?

Hi all, at the speed AI is running, we now run claude code with the super powers plugin, its second to none, we almost get no re work , so long as the prd is spec'd and architected correctly. Using subagents starting with opus at top level, down to sonnet sub agent on execution.
