 2. Update `Tool.define()` factory to work with Effects
 3. Update `SessionPrompt` to `yield*` tool results instead of `await`ing
 
+### Tool migration details
+
+Until the tool interface itself returns `Effect`, use this transitional pattern for migrated tools:
+
+- `Tool.defineEffect(...)` should `yield*` the services the tool depends on and close over them in the returned tool definition.
+- Keep the bridge at the Promise boundary only. Prefer a single `Effect.runPromise(...)` in the temporary `async execute(...)` implementation, and move the inner logic into `Effect.fn(...)` helpers instead of scattering `runPromise` islands through the tool body.
+- If a tool starts requiring new services, wire them into `ToolRegistry.defaultLayer` so production callers resolve the same dependencies as tests.
+
+Tool tests should use the existing Effect helpers in `packages/opencode/test/lib/effect.ts`:
+
+- Use `testEffect(...)` / `it.live(...)` instead of creating fake local wrappers around effectful tools.
+- Yield the real tool export, then initialize it: `const info = yield* ReadTool`, `const tool = yield* Effect.promise(() => info.init())`.
+- Run tests inside a real instance with `provideTmpdirInstance(...)` or `provideInstance(tmpdirScoped(...))` so instance-scoped services resolve exactly as they do in production.
+
+This keeps migrated tool tests aligned with the production service graph today, and makes the eventual `Tool.Info` → `Effect` cleanup mostly mechanical later.
+
 Individual tools, ordered by value:
 
 - [ ] `apply_patch.ts` — HIGH: multi-step orchestration, error accumulation, Bus events
 - [ ] `bash.ts` — HIGH: shell orchestration, quoting, timeout handling, output capture
-- [ ] `read.ts` — HIGH: streaming I/O, readline, binary detection → FileSystem + Stream
+- [x] `read.ts` — HIGH: streaming I/O, readline, binary detection → FileSystem + Stream
 - [ ] `edit.ts` — HIGH: multi-step diff/format/publish pipeline, FileWatcher lock
 - [ ] `grep.ts` — MEDIUM: spawns ripgrep → ChildProcessSpawner, timeout handling
 - [ ] `write.ts` — MEDIUM: permission checks, diagnostics polling, Bus events

+What we would change if we could
+
+## Keybindings vs. Keymappings
+
+Make it `keymappings`, closer to neovim. Can be layered like `<leader>abc`. Commands don't define their binding, but have an id that a key can be mapped to like
+
+```ts
+{ key: "ctrl+w", cmd: string | function, description }
+```
+
+_Why_
+Currently its keybindings that have an `id` like `message_redo` and then a command can use that or define it's own binding. While some keybindings are just used with `.match` in arbitrary key handlers and there is no info what the key is used for, except the binding id maybe. It also is unknown in which context/scope what binding is active, so a plugin like `which-key` is nearly impossible to get right.

-# Skills
-
-Skills are reusable, composable capabilities that enhance your abilities. Each skill is a self-contained directory with a `SKILL.md` file that contains instructions, examples, and/or reference material.
-
-## What are skills?
-
-Skills are modular extensions that provide:
-
-- Specialized knowledge: Domain-specific expertise (e.g., PDF processing, data analysis)
-- Workflow patterns: Best practices for common tasks
-- Tool integrations: Pre-configured tool chains for specific operations
-- Reference material: Documentation, templates, and examples
-
-## How to use skills
-
-Identify the skills that are likely to be useful for the tasks you are currently working on, use the `skill` tool to load a skill for detailed instructions, guidelines, scripts and more.
-
-Only load skill details when needed to conserve the context window.
-
 # Ultimate Reminders
 
 At any time, you should be HELPFUL, CONCISE, and ACCURATE. Be thorough in your actions — test what you build, verify what you change — not in your explanations.
