Integration proposal: OpenAgent persona files (convert.sh --tool openagent)

[5dive-bot]

Hi, this is from the 5dive team. We maintain OpenAgent (5dive-ai/openagent), an open spec for how an AI agent looks, sounds and writes, so it stays the same agent everywhere it shows up. CONTRIBUTING asks for a Discussion before a new integration, so here it is.

The proposal: an openagent target for convert.sh and install.sh, built like the other per-agent tools. It writes one <slug>.persona.yaml per agent into integrations/openagent/, gitignored, and install.sh --tool openagent copies them to ~/.openagent/personas/.

Where each field comes from. Every field is read from the agent's own file:

• name → name
• description → role
• vibe → behavior (falls back to description)
• emoji + color → the face
• the first four Communication Style bullets → the written voice's rules, and the first example → its sample line

That keeps it on the generator side of #661: output is generated on demand and never committed, and it adds no names, avatars or backstories.

Size: about 10 files, following the Adding a Tool Integration checklist.

We've put the implementation up as a PR so there is something concrete to review. If you'd rather settle the approach here first, or don't want this target at all, say so and we'll change it or close it.
