+# Subagent Type Catalogue
+
+The 34 role-based subagent types dispatchable via the opencode `Task` tool.
+Each type has one tracking issue in this repo, tagged `agent-catalogue`.
+
+> Distinct from the **persona** agents in [[Agent-Registry]] (Kimiko/Kairo/
+> Shimaguru). Personas are persistent identities; subagent types are capability
+> profiles spun up on demand.
+

+
+## Dispatch guidance
+
+- **Single-file edit / quick lookup** -> do NOT use a subagent; call the tool directly.
+- **Whole-codebase / >5 interdependent steps** -> `general` or `explore`.
+- **Planning a new feature** -> `left-side-of-v` (or `phase1-researcher` -> `phase2-designer`).
+- **Implementation** -> `phase3-implementer` / `disciplined-implementation` / `developer`.
+- **Pre-merge assurance** -> `right-side-of-v` / `overseer` / `quality-reviewer`.
+- **Rust-specific** -> `rust-code-reviewer` / `rust-performance-expert` / `debugger`.
+- **Adversarial / risk** -> `via-negativa-analyst` / `perspective-investigator`.
+
+## Tracking issues
+
+Each type has an open issue titled `Agent: <Name> — <role>`, labelled
+`agent-catalogue` + `type:task` + `workflow:ready`. Filter:
+
+`gtr list-issues --owner terraphim --repo agent-tasks --labels agent-catalogue`
