# How Jessica Kerr actually uses coding agents

Symmathesy, Honeycomb

**If you take one thing:** `Capability Owners`, standing agents per feature. her create-owner skill appoints a standing Owner for each capability, a knowledge base plus instructions a fresh subagent follows, so 'everything else still works' has someone to check it.

- **Agent:** Claude Code ([source, 2026-04-27](https://jessitron.com/2026/04/27/communication-is-hard-but-sometimes-i-can-fix-it/))
- **Model:** Claude Opus 5.5 ([source, 2026-10-06](https://github.com/jessitron/mtg-deck-shuffler/commit/d463957d0b6fc318f18f4ae7fb570792dd310727))
- **Model:** Claude Sonnet 5.5 ([source, 2026-10-06](https://github.com/jessitron/mtg-deck-shuffler/commit/c46ce455543f0e947589341095a68a1d775e108b))
- **Review:** A reviewer agent checks each PR against a stated correctness condition; her own reviews fix the system ([source, 2026-04-06](https://jessitron.com/2026/04/06/adding-correctness-conditions-to-code-changes/))
- **Harness:** Claude Code with her seamapping plugin; subagents spawned freely ([source, 2026-10-06](https://github.com/jessitron/mtg-deck-shuffler/blob/d463957d0b6fc318f18f4ae7fb570792dd310727/CLAUDE.md#L10-L12))
- **Rules file:** CLAUDE.md (fleet-level, plus one per app) ([source, 2026-10-06](https://github.com/jessitron/mtg-deck-shuffler/blob/d463957d0b6fc318f18f4ae7fb570792dd310727/CLAUDE.md#L13-L15))
- **Skills:** begin-voyage, establish-tracking, orient, drop-buoy, request-skill-change, create-owner, give-yourself-a-script, one-time-test ([source, 2026-08-23](https://github.com/jessitron/tronijess-skills/blob/f2e1d10e61376c756892d109f74fd50c076d3ff2/README.md#L15-L55))
- **MCP servers:** honeycomb ([source, 2026-10-06](https://github.com/jessitron/mtg-deck-shuffler/blob/d463957d0b6fc318f18f4ae7fb570792dd310727/.mcp.json#L3-L6))

## In their words

> The work: I’m getting Claude to build a program that turns Claude conversation logs into a vertical HTML comic.

> Verification – We can add a reviewer agent to check each PR for missed documentation updates.

> - **Spawn subagents whenever it's a good idea** — don't wait to be asked.
