+# Runtime-Aware Subagent Dispatch (epic #2505 Phase 4 / #2508)
+
+GSD workflows dispatch specialized subagents by role (planner, executor,
+verifier, …). On **named-dispatch runtimes** (Claude Code, OpenCode, Cursor,
+Cline, … — every runtime whose descriptor declares `hostIntegration.dispatch.namedDispatch: true`), the role name dispatches the named subagent directly.
+
+On **built-in-only runtimes** (kimi-code — three built-in subagents only:
+`coder`, `explore`, `plan`; no custom registration per
+`moonshotai.github.io/kimi-code/en/customization/agents`), a GSD role name is
+unknown and the dispatch must use the closest built-in.
+
+## Resolution
+
+Before dispatching a subagent by role, resolve the type for the current runtime
+via the `resolve-dispatch-type` query. Pass the requested role name; the query
+returns the name unchanged on named-dispatch runtimes and maps to the closest
+built-in (`coder`/`explore`/`plan`) on kimi-code. The `|| echo` fallback
+preserves named-dispatch behavior on older GSD installs that lack the query.
+
+The persona rides `${AGENT_SKILLS_<ROLE>}` (Phase 3 / #2510) regardless of the
+resolved type — on non-Claude runtimes with no `agent_skills` config,
+`gsd-tools query agent-skills <role>` returns the installed agent prompt as
+the block. So a coder dispatch with the planner persona injected gives kimi-code
+the planner's behavior in the coder built-in's process.
+
+## Suffix → built-in map
+
+| Agent role suffix | Built-in | Rationale |
+|---|---|---|
+| `-planner`, `-roadmapper`, `-selector`, `-spec` | `plan` | Plans/designs; no file writes |
+| `-researcher`, `-mapper`, `-checker`, `-verifier`, `-auditor`, `-analyzer`, `-synthesizer`, `-profiler`, `-curator`, `-classifier`, `-reviewer` | `explore` | Read-only investigation |
+| everything else (`-executor`, `-fixer`, `-writer`, `-debugger`, …) | `coder` | General-purpose with full tool set |
+| `general-purpose`, `general`, `default`, `sonnet`, `opus`, `haiku` | `coder` | Already-generic names |
+
+## Why not a hook?
+
+Kimi Code's documented PreToolUse hook API
+(`moonshotai.github.io/kimi-code/en/customization/hooks`) supports only
+`permissionDecision: allow|deny` on blockable events — it cannot rewrite the
+dispatch payload's role field in flight. A PreToolUse-remap hook (the epic's
+original "Option B") is therefore infeasible; this per-dispatch resolution
+(Option A) is the documented-API-correct path.
