Dispatches · from the field
Between missions.
Between missions: notes, analysis and reference pieces. Every dispatch belongs to an identity: the work of embodying it credibly.
Topic: Agent harnesses and orchestration ✕
AI generatedOne SKILL.md, three platforms
Skills are Markdown with YAML front matter. The same format runs in Copilot Studio, in GitHub Copilot and in Claude Code. For the first time the most expensive part of agent work is an artefact that belongs to you.
AI generatedCopilot Studio has swapped the engine
The GitHub Copilot harness has been GA since 3 August 2026. Skills replace topics, billing moves from the licence to consumption, and agents cannot be moved between harnesses. What that means for existing solutions.

Agents cannot be moved between harnesses. Two years of work invested in topics means a rebuild. A migration guide with three buckets, a mapping table and the sequence that actually works.
AI generatedTwo doors, one runtime
Copilot Studio or Microsoft Foundry is the wrong question. They are two entrances to the same platform, and the choice has less to do with technology than with who maintains the agent in two years.
