+
+## What this is
+
+Ready `@corbits/code-agent-planner` agent + independently importable components:
+`agent`, `defineAgent`, `director`, `tools`, `systemPrompt`, `config`.
+
+## Consume (runLocal)
+
+```ts
+import { agent } from "@corbits/code-agent-planner";
+const run = runLocal(defining(agent), env);
+```
+
+## Consume (deploy runWorkflow / hub / sidecar)
+
+Hand the same `AgentDefinition` to a workflow — the package never exports a
+workflow itself.
+
+## Remix components
+
+```ts
+import { director, tools, systemPrompt, config } from "@corbits/code-agent-planner";
+defineAgent({ director, ... }); // or swap tools / systemPrompt / config
+```
+
+Each of `director`, `tools`, `systemPrompt`, and `config` is a named,
+independently importable part.
+
+## Single authority
+
+`prompt.ts` `systemPrompt.build()` is byte-stable (the raw card, no formatting).
+`toolset.ts` `tools` literal equals the `REVIEW_TOOLS` surface constant in
+`src/agent/directors/tool-sets.ts`; drift is enforced by the in-tree drift-guard
+`src/agent/directors/planner/package.test.ts`.
