 ## Overview
 
-Hive is a runtime harness for AI agents in production. You describe your goal in natural language; a coding agent (the queen) generates the agent graph and connection code to achieve it. During execution, the harness manages state isolation, checkpoint-based crash recovery, cost enforcement, and real-time observability. When agents fail, the framework captures failure data, evolves the graph through the coding agent, and redeploys automatically. Built-in human-in-the-loop nodes, browser control, credential management, and parallel execution give you production reliability without sacrificing adaptability.
+OpenHive is a zero-setup, model-agnostic execution harness that dynamically generates multi-agent topologies to tackle complex, long-running business workflows without requiring any orchestration boilerplate. By simply defining your objective, the runtime compiles a strict, graph-based execution DAG that safely coordinates specialized agents to execute concurrent tasks in parallel. Backed by persistent, role-based memory that intelligently evolves with your project's context, OpenHive ensures deterministic fault tolerance, deep state observability, and seamless asynchronous execution across whichever underlying LLMs you choose to plug in.
+
+## Features

+- ✅ Multi-Agent Coordination for parallel task execution 
+- ✅ Graph-based execution for recurring and complex processes 
+- ✅ Role-based memory that evolves with your projects 
+- ✅ Zero Setup - No technical configuration required
+- ✅ General Compute Use and Browser Use with Native Extension 
+- ✅ Custom Model Support

-## Features
-
-- **Browser-Use** - Control the browser on your computer to achieve hard tasks
-- **Parallel Execution** - Execute the generated graph in parallel. This way you can have multiple agents completing the jobs for you
-- **[Goal-Driven Generation](docs/key_concepts/goals_outcome.md)** - Define objectives in natural language; the coding agent generates the agent graph and connection code to achieve them
-- **[Adaptiveness](docs/key_concepts/evolution.md)** - Framework captures failures, calibrates according to the objectives, and evolves the agent graph
-- **[Dynamic Node Connections](docs/key_concepts/graph.md)** - No predefined edges; connection code is generated by any capable LLM based on your goals
-- **SDK-Wrapped Nodes** - Every node gets a shared data buffer, local RLM memory, monitoring, tools, and LLM access out of the box
-- **[Human-in-the-Loop](docs/key_concepts/graph.md#human-in-the-loop)** - Intervention nodes that pause execution for human input with configurable timeouts and escalation
-- **Real-time Observability** - WebSocket streaming for live monitoring of agent execution, decisions, and node-to-node communication

-### Credential Check (MANDATORY)
+### Credential Check
 
-The summary from list_agent_tools() includes `credentials_required` and \
-`credentials_available` per provider. **Before designing the graph**, check \
-which providers the design will need and whether credentials are available.
+Your **Connected integrations** block (in your system prompt above) is the \
+authoritative list of credentials currently connected for this user. It is \
+refreshed on every turn — you do not need to call list_credentials to \
+discover what is available. Treat the block as ground truth for connectivity.
 
-For each provider whose tools you plan to use and where \
-`credentials_available` is false:
-- Tell the user which credential is missing and what it's needed for
-- Ask if they have access to set it up (e.g., API key, OAuth, service account)
-- If they don't have access, adjust the design to work without that provider \
-or suggest alternatives
+**Important:** the block shows connectivity only, not liveness. OAuth tokens \
+can expire between turns. The framework refreshes tokens automatically when \
+a tool is called. If a refresh fails, the tool result you receive will be a \
+structured payload of the form:
 
-**Do NOT proceed to the design step with tools that require unavailable \
-credentials without the user acknowledging it.** Finding out at runtime that \
-credentials are missing wastes everyone's time. Surface this early.
+```
+{"error": "credential_expired", "credential_id": "...", "provider": "...", \
+"alias": "...", "reauth_url": "..."}
+```
+
+When you see this:
+1. Stop the branch of work that needed that credential — do **not** retry.
+2. Tell the user which integration needs reauthorization (use the alias if \
+present) and surface the `reauth_url` so they can fix it.
+3. Wait for the user to confirm they have reauthorized before retrying.
+
+**Before designing the layout**, cross-check which providers your design \
+needs against the Connected integrations block. If a provider is missing \
+entirely (not just expired), tell the user and ask whether they can connect \
+it or whether you should design around it.
 
 Example:
-> "The design needs Google Sheets tools, but the `google` credential isn't \
-configured yet. Do you have a Google service account or OAuth credentials \
-you can set up? If not, I can use CSV file output instead."
+> "The design needs Google Sheets, but I don't see a `google` integration \
+in your connected integrations. Can you connect one, or should I use CSV \
+file output instead?"
+
+`list_credentials` is still available as a diagnostic tool for inspecting \
+specific credentials by id, but it is no longer part of the planning happy \
+path — the ambient block already gives you everything you need.

+
+## Forking the session into a persistent colony
+
+**Prove the work inline BEFORE scaling to a colony.** This is the \
+most important rule in this section. A colony is a durable, \
+unattended runtime — you must know the task mechanics work before \
+you bake them into one. The expensive, hard-to-debug failures \
+(dummy-target browser loops, wrong selectors, misread skills) \
+happen when a queen delegates to a colony without ever doing \
+the work herself first.
+
+**The inline-first, scale-after pattern:**
+
+  1. **Do one instance of the work yourself, inline**, right in \
+     this chat. Use your own tools. Open the browser, click the \
+     real button, type the real text, send the real message, \
+     verify the real result. This is the shortest path from \
+     "vague intent" to "known-working procedure" — you learn \
+     the exact selectors, the exact quirks, the exact sequence \
+     that works on this site / API / system right now.
+
+  2. **Report the result to the user.** "I sent the message to \
+     Dimitris — here's the confirmation. Before I scale this to \
+     your whole connection list, want me to tweak anything?" \
+     This gives the user a concrete sample to react to AND \
+     gives you feedback before the cost of scaling multiplies.
+
+  3. **Only after a successful inline run**, decide whether to:
+     - stay inline and iterate by hand (small batches)
+     - fan out via `run_parallel_workers` (one-shot batch, \
+       results needed RIGHT NOW, no persistence needed)
+     - scale via `create_colony` (headless / recurring / needs \
+       to survive this chat ending)
+
+**When to use create_colony:** after step 2 has succeeded, and \
+the user needs work to run **headless, recurring, or in parallel \
+to this chat**. Typical triggers:
+  - "run this every morning / every hour / on a cron"
+  - "keep monitoring X and alert me when Y"
+  - "fire this off in the background, I'll check on it later"
+  - "spin up a dedicated agent for this so I can keep working here"
+  - any task that should survive the current conversation ending
+
+**When NOT to use it:**
+  - You haven't actually done the work once yet. STOP. Do it \
+    inline first. Delegating an untested procedure to a colony \
+    is the single most common cause of silent worker failure.
+  - The user wants results RIGHT NOW and doesn't need the task \
+    to persist → stay inline or use `run_parallel_workers`.
+  - You "learned something reusable" but there's no operational \
+    need to keep running — knowledge worth saving goes in a \
+    skill file, not a colony.
+
+**Two-step flow (assuming step 1-2 above have succeeded):**
+  1. AUTHOR A SKILL FIRST so the colony worker has the operational \
+     context it needs to run unattended — and write it from the \
+     knowledge you just earned doing the work inline, not from \
+     speculation. Include the EXACT selectors, tool call \
+     sequences, and gotchas you hit in your own run. Use \
+     write_file to create the skill folder (recommended \
+     location: `~/.hive/skills/{skill-name}/SKILL.md`). The \
+     SKILL.md needs YAML frontmatter with `name` (matching the \
+     directory name) and `description` (1-1024 chars including \
+     trigger keywords), followed by a markdown body. Optional \
+     subdirs: scripts/, references/, assets/. Read your \
+     writing-hive-skills default skill for the full spec.
+  2. create_colony(colony_name, task, skill_path) — Validates the \
+     skill folder, installs it under ~/.hive/skills/ if it isn't \
+     already there, and forks this session into a new colony. \
+     The colony worker inherits your full conversation at spawn \
+     time, so it sees everything you already did and said — no \
+     repeated discovery. NOTHING RUNS immediately after this \
+     call: the task is baked into worker.json and the user starts \
+     the worker (or wires up a trigger) later from the new colony \
+     page. The task string still must be FULL and self-contained \
+     because triggers fire without your chat context.

 # System Rules
 
-## ask_user (CRITICAL)
+## Communication
+
+Plain-text output IS how you talk to the user — your response is \
+displayed directly in the chat. Use text for conversational replies, \
+open-ended questions, explanations, and short status updates before \
+tool calls. When the user just wants to chat, chat back naturally; \
+you don't need a tool call to "hand off" the turn — the system \
+detects the end of your response and waits for their next message.
+
+## Visible response channel
+
+Your visible response is the plain text in your LLM reply — the text \
+you write after the closing `<tone>` tag of your internal assessment. \
+NEVER use `run_command`, `echo`, or any other tool to emit what you \
+want the user to read. Tools are for work: reading files, running \
+commands, searching, editing. Tools are not for speaking. If you \
+ever find yourself about to call `run_command("echo ...")` to say \
+something, stop — write it as plain text instead. The LLM reply \
+itself is the channel; there is no other.
+
+## ask_user / ask_user_multiple
+
+Use these tools ONLY when you need the user to pick from a small set \
+of concrete options — approval gates, structured preference questions, \
+decision points with 2-4 clear alternatives. Typical triggers:
+- "Postgres or SQLite?" use ask_user tool with options
+- "Approve this draft? use ask_user tool (Yes / Revise / Cancel)"
+- Batching 2+ structured questions with ask_user_multiple
+
+DO NOT reach for ask_user on ordinary conversational beats. "What's \
+your name?", "Tell me more about that", "How are you?" — just write \
+those as text. Free-form questions belong in prose. Using ask_user \
+for every reply feels robotic and blocks natural conversation. \
+When you do use it, keep your text to a brief intro; the widget \
+renders the question and options.
+
+## Chatting vs acting
+
+**When the user greets you or chats, reply in plain prose — no tool \
+calls.** A bare "hi", "hey", "hello", "how's it going" is a \
+conversational opener, not a hidden task. Do NOT call `list_directory`, \
+`search_files`, `run_command`, `ask_user`, or any other tool to \
+"discover" what they want. Instead, check what you already know about \
+this user from your recall memory — their name, role, past topics, \
+preferences — and write a 1–2 sentence greeting in character that \
+references it. If you know their name, use it. If you remember what \
+you last worked on together, reference it. Then stop and wait. They \
+will bring the task when they have one. Presuming a task that wasn't \
+stated is worse than waiting a turn.
+
+**When the user asks you to DO something** (build, edit, run, \
+investigate, search), call the appropriate tool directly on the same \
+turn — don't narrate intent and stop. "Let me check that file." \
+followed by an immediate read_file is fine; "I'll check that file." \
+with no tool call and then waiting is not. If you can act now, act now.
 
-Any response that expects user input MUST end with ask_user or \
-ask_user_multiple. The system cannot detect you're waiting otherwise. \
-Never write questions as plain text without the tool call. \
-For 2+ questions, use ask_user_multiple so users answer in one go. \
-Keep your text to a brief intro -- the widget renders the questions. \
-Always provide 2-4 short options; users can type custom responses.

-- `browser_start`, `browser_open` -- launch/navigate
-- `browser_click`, `browser_fill`, `browser_type` -- interact
-- `browser_snapshot` -- read page content (preferred over screenshot)
-- `browser_screenshot` -- visual capture
-- `browser_scroll`, `browser_wait` -- navigation helpers
-- `browser_evaluate` -- run JavaScript
+- `browser_start`, `browser_open`, `browser_navigate` — launch/navigate
+- `browser_click`, `browser_click_coordinate`, `browser_fill`, `browser_type`, `browser_type_focused` — interact
+- `browser_press` (with optional `modifiers=["ctrl"]` etc.) — keyboard shortcuts
+- `browser_snapshot` — compact accessibility-tree read (structured)
+<!-- vision-only -->
+- `browser_screenshot` — visual capture (annotated PNG)
+<!-- /vision-only -->
+- `browser_shadow_query`, `browser_get_rect` — locate elements (shadow-piercing via `>>>`)
+- `browser_scroll`, `browser_wait` — navigation helpers
+- `browser_evaluate` — run JavaScript
+- `browser_close`, `browser_close_finished` — tab cleanup
 
-## System Prompt Tips for Browser Nodes
+## Pick the right reading tool
+
+**`browser_snapshot`** — compact accessibility tree of interactive elements. Fast, cheap, good for static or form-heavy pages where the DOM matches what's visually rendered (documentation, simple dashboards, search results, settings pages).
+
+**`browser_screenshot`** — visual capture + metadata (`cssWidth`, `devicePixelRatio`, scale fields). **Use this on any complex SPA** — LinkedIn, Twitter/X, Reddit, Gmail, Notion, Slack, Discord, any site using shadow DOM, virtual scrolling, React reconciliation, or dynamic layout. On these pages, snapshot refs go stale in seconds, shadow contents aren't in the AX tree, and virtual-scrolled elements disappear from the tree entirely. Screenshot is the **only** reliable way to orient yourself.
+
+Neither tool is "preferred" universally — they're for different jobs. Default to snapshot on text-heavy static pages, screenshot on SPAs and anything shadow-DOM-heavy. Activate the `browser-automation` skill for the full decision tree.
+
+## Coordinate rule
+
+Every browser tool that takes or returns coordinates operates in **fractions of the viewport (0..1 for both axes)**. Read a target's proportional position off `browser_screenshot` ("~35% from the left, ~20% from the top" → `(0.35, 0.20)`) and pass that to `browser_click_coordinate` / `browser_hover_coordinate` / `browser_press_at`. `browser_get_rect` and `browser_shadow_query` return `rect.cx` / `rect.cy` as fractions. The tools multiply by `cssWidth` / `cssHeight` internally — no scale awareness required. Fractions are used because every vision model (Claude, GPT-4o, Gemini, local VLMs) resizes/tiles images differently; proportions are invariant. Avoid raw `getBoundingClientRect()` via `browser_evaluate` for coord lookup; use `browser_get_rect` instead.
+
+## System prompt tips for browser nodes
 
 ```
-1. Use browser_snapshot() to read page content (NOT browser_get_text)
-2. Use browser_wait(seconds=2-3) after navigation for page load
-3. If you hit an auth wall, call set_output with an error and move on
-4. Keep tool calls per turn <= 10 for reliability
+1. On LinkedIn / X / Reddit / Gmail / any SPA — use browser_screenshot to orient,
+   not browser_snapshot. Shadow DOM and virtual scrolling make snapshots unreliable.
+2. For static pages (docs, forms, search results), browser_snapshot is fine.
+3. Before typing into a rich-text editor (X compose, LinkedIn DM, Gmail, Reddit),
+   click the input area first with browser_click_coordinate so React / Draft.js /
+   Lexical register a native focus event, then use browser_type_focused(text=...)
+   for shadow-DOM inputs or browser_type(selector, text) for light-DOM inputs.
+4. Use browser_wait(seconds=2-3) after navigation for SPA hydration.
+5. If you hit an auth wall, call set_output with an error and move on.
+6. Keep tool calls per turn <= 10 for reliability.
 ```

 Follow these rules for reliable, efficient browser interaction.
 
-## Reading Pages
-- ALWAYS prefer `browser_snapshot` over `browser_get_text("body")`
-  — it returns a compact ~1-5 KB accessibility tree vs 100+ KB of raw HTML.
-- Interaction tools (`browser_click`, `browser_type`, `browser_fill`,
-  `browser_scroll`, etc.) return a page snapshot automatically in their
-  result. Use it to decide your next action — do NOT call
-  `browser_snapshot` separately after every action.
-  Only call `browser_snapshot` when you need a fresh view without
-  performing an action, or after setting `auto_snapshot=false`.
-- Do NOT use `browser_screenshot` to read text — use
-  `browser_snapshot` for that (compact, searchable, fast).
-- DO use `browser_screenshot` when you need visual context:
-  charts, images, canvas elements, layout verification, or when
-  the snapshot doesn't capture what you need.
-- Only fall back to `browser_get_text` for extracting specific
-  small elements by CSS selector.
+## Pick the right reading tool
 
-## Navigation & Waiting
-- `browser_navigate` and `browser_open` already wait for the page to
-  load (`domcontentloaded`). Do NOT call `browser_wait` with no
-  arguments after navigation — it wastes time.
-  Only use `browser_wait` when you need a *specific element* or *text*
-  to appear (pass `selector` or `text`).
-- NEVER re-navigate to the same URL after scrolling
-  — this resets your scroll position and loses loaded content.
+- **`browser_snapshot`** — compact accessibility tree. Fast, cheap, good
+  for static / text-heavy pages where the DOM matches what's visually
+  rendered (docs, forms, search results, settings pages).
+- **`browser_screenshot`** — visual capture + scale metadata. Use on any
+  complex SPA (LinkedIn, X / Twitter, Reddit, Gmail, Notion, Slack,
+  Discord) and on any site using shadow DOM or virtual scrolling. On
+  those pages, snapshot refs go stale in seconds, shadow contents
+  aren't in the AX tree, and virtual-scrolled elements disappear from
+  the tree entirely — screenshots are the only reliable way to orient.
+
+Neither tool is "preferred" universally — they're for different jobs.
+Default to snapshot on static pages, screenshot on SPAs and
+shadow-heavy sites. Interaction tools (click/type/fill/scroll) return
+a snapshot automatically, so don't call `browser_snapshot` separately
+after an interaction unless you need a fresh view.
+
+Only fall back to `browser_get_text` for extracting small elements by
+CSS selector.
+
+## Coordinates
+
+Every browser tool that takes or returns coordinates operates in
+**fractions of the viewport (0..1 for both axes)**. Read a target's
+proportional position off `browser_screenshot` — "this button is
+~35% from the left, ~20% from the top" → pass `(0.35, 0.20)`.
+`browser_get_rect` and `browser_shadow_query` return `rect.cx` /
+`rect.cy` as fractions in the same space. The tools handle the
+fraction → CSS-px multiplication internally; you do not need to
+track image pixels, DPR, or any scale factor.
+
+Why fractions: every vision model (Claude, GPT-4o, Gemini, local
+VLMs) resizes or tiles images differently before the model sees the
+pixels. Proportions survive every such transform; pixel coordinates
+only "work" per-model and break when you swap backends.
+
+Avoid raw `browser_evaluate` + `getBoundingClientRect()` for coord
+lookup — that returns CSS px and will be wrong when fed to click
+tools. Prefer `browser_get_rect` / `browser_shadow_query`, which
+return fractions.
+
+## Rich-text editors (X, LinkedIn DMs, Gmail, Reddit, Slack, Discord)
+
+Click the input area first with `browser_click_coordinate` or
+`browser_click(selector)` BEFORE typing. React / Draft.js / Lexical /
+ProseMirror only register input as "real" after a native pointer-
+sourced focus event; JS `.focus()` is not enough. Without a real click
+first, the editor stays empty and the send button stays disabled.
+
+`browser_type` does this automatically when you have a selector — it
+clicks the element, then inserts text via CDP `Input.insertText`.
+For shadow-DOM inputs where selectors can't reach, use
+`browser_click_coordinate` to focus, then `browser_type_focused(text=...)`
+to type into the active element. Before clicking send, verify the
+submit button's `disabled` / `aria-disabled` state via `browser_evaluate`.
+
+## Shadow DOM
+
+Sites like LinkedIn messaging (`#interop-outlet`), Reddit (faceplate
+Web Components), and some X elements live inside shadow roots.
+`document.querySelector` and `wait_for_selector` do **not** see into
+shadow roots. But `browser_click_coordinate` **does** — CDP hit
+testing walks shadow roots natively, so coordinate-based operations
+reach shadow elements transparently.
+
+**Shadow-heavy site workflow:**
+1. `browser_screenshot()` → visual image
+2. Identify target visually → pixel `(x, y)` read straight off the image
+3. `browser_click_coordinate(x, y)` → lands via native hit test;
+   inputs get focused regardless of shadow depth
+4. Type via `browser_type_focused` (no selector needed — types into the
+   already-focused element), or `browser_type` if you have a selector
+
+For selector-style access when you know the shadow path:
+`browser_shadow_query("#interop-outlet >>> #msg-overlay >>> p")` —
+returns a CSS-px rect you can feed directly to click tools.
+
+## Navigation & waiting
+
+- `browser_navigate(wait_until="load")` returns when the page fires
+  load. On SPAs (LinkedIn especially — 4–5 seconds), add a 2–3 s sleep
+  after to let React/Vue hydrate before querying for chrome elements.
+- Never re-navigate to the same URL after scrolling — resets scroll.
+- Use `timeout_ms=20000` for heavy SPAs.
+- `wait_for_selector` / `wait_for_text` resolve in milliseconds when
+  the element is already in the DOM — no need to sleep if you can
+  express the wait condition.
+
+## Keyboard shortcuts
+
+`browser_press("a", modifiers=["ctrl"])` for Ctrl+A. Accepted
+modifiers: `"alt"`, `"ctrl"`/`"control"`, `"meta"`/`"cmd"`,
+`"shift"`. The tool dispatches the modifier key first, then the main
+key with `code` and `windowsVirtualKeyCode` populated (Chrome's
+shortcut dispatcher requires both), then releases in reverse order.
 
 ## Scrolling
-- Use large scroll amounts ~2000 when loading more content
-  — sites like twitter and linkedin have lazy loading for paging.
-- The scroll result includes a snapshot automatically — no need to call
-  `browser_snapshot` separately.
 
-## Batching Actions
-- You can call multiple tools in a single turn — they execute in parallel.
-  ALWAYS batch independent actions together. Examples:
-  - Fill multiple form fields in one turn.
-  - Navigate + snapshot in one turn.
-  - Click + scroll if targeting different elements.
-- When batching, set `auto_snapshot=false` on all but the last action
-  to avoid redundant snapshots.
-- Aim for 3-5 tool calls per turn minimum. One tool call per turn is
-  wasteful.
+- Use large amounts (~2000 px) for lazy-loaded sites (X, LinkedIn).
+- Scroll result includes a snapshot — don't call `browser_snapshot`
+  separately.
 
-## Error Recovery
-- If a tool fails, retry once with the same approach.
-- If it fails a second time, STOP retrying and switch approach.
-- If `browser_snapshot` fails → try `browser_get_text` with a
-  specific small selector as fallback.
-- If `browser_open` fails or page seems stale → `browser_stop`,
-  then `browser_start`, then retry.
+## Batching
 
-## Tab Management
+- Multiple tool calls per turn execute in parallel. Batch independent
+  actions together: fill multiple fields, navigate + snapshot,
+  different-target click + scroll.
+- Set `auto_snapshot=false` on all but the last when batching.
+- Aim for 3–5 tool calls per turn minimum.
 
-**Close tabs as soon as you are done with them** — not only at the end of the task.
-After reading or extracting data from a tab, close it immediately.
+## Tab management
 
-**Decision rules:**
-- Finished reading/extracting from a tab? → `browser_close(target_id=...)`
-- Completed a multi-tab workflow? → `browser_close_finished()` to clean up all your tabs
-- More than 3 tabs open? → stop and close finished ones before opening more
-- Popup appeared that you didn't need? → close it immediately
+Close tabs as soon as you're done with them — not only at the end of
+the task. `browser_close(target_id=...)` for one, `browser_close_finished()`
+for a full cleanup. Never accumulate more than 3 open tabs.
+`browser_tabs` reports an `origin` field: `"agent"` (you own it, close
+when done), `"popup"` (close after extracting), `"startup"`/`"user"`
+(leave alone).
 
-**Origin awareness:** `browser_tabs` returns an `origin` field for each tab:
-- `"agent"` — you opened it; you own it; close it when done
-- `"popup"` — opened by a link or script; close after extracting what you need
-- `"startup"` or `"user"` — leave these alone unless the task requires it
+## Login & auth walls
 
-**Cleanup tools:**
-- `browser_close(target_id=...)` — close one specific tab
-- `browser_close_finished()` — close all your agent/popup tabs (safe: leaves startup/user tabs)
-- `browser_close_all()` — close everything except the active tab (use only for full reset)
+Report the auth wall and stop — do NOT attempt to log in. Dismiss
+cookie consent banners if they block content.
 
-**Multi-tab workflow pattern:**
-1. Open background tabs with `browser_open(url=..., background=true)` to stay on current tab
-2. Process each tab and close it with `browser_close` when done
-3. When the full workflow completes, call `browser_close_finished()` to confirm cleanup
-4. Check `browser_tabs` at any point — it shows `origin` and `age_seconds` per tab
+## Error recovery
 
-Never accumulate tabs. Treat every tab you open as a resource you must free.
+- Retry once on failure, then switch approach.
+- If `browser_snapshot` fails, try `browser_get_text` with a narrow
+  selector as fallback.
+- If `browser_open` fails or the page seems stale, `browser_stop` →
+  `browser_start` → retry.
 
-## Shadow DOM & Overlays
+## `browser_evaluate`
 
-Some sites (LinkedIn messaging, etc.) render content inside closed shadow roots that are
-invisible to regular DOM queries and `browser_snapshot` coordinates.
-
-**Detecting shadow DOM**: `document.elementFromPoint(x, y)` returns a zero-height host element
-(e.g. `#interop-outlet`) for the entire overlay area — this is normal, not a bug.
-`document.body.innerText` and `document.querySelectorAll` return nothing for shadow content.
-`browser_snapshot` CAN read shadow DOM text but cannot return coordinates.
-
-**Querying into shadow DOM:**
-```
-browser_shadow_query("#interop-outlet >>> #msg-overlay >>> p")
-```
-Uses `>>>` to pierce shadow roots. Returns `rect` in CSS pixels and `physicalRect` ready for
-`browser_click_coordinate` / `browser_hover_coordinate`.
-
-**Getting physical rect for any element (including shadow DOM):**
-```
-browser_get_rect(selector="#interop-outlet >>> .msg-convo-wrapper", pierce_shadow=true)
-```
-
-**Manual JS traversal when selector is dynamic:**
-```js
-const shadow = document.getElementById('interop-outlet').shadowRoot;
-const convo = shadow.querySelector('#ember37');
-const rect = convo.querySelector('p').getBoundingClientRect();
-// rect is in CSS pixels — multiply by DPR for physical pixels
-```
-Pass this as a multi-statement script to `browser_evaluate`; it wraps automatically in an IIFE.
-Use `JSON.stringify(rect)` to serialize the result.
-
-## Coordinate System
-
-There are THREE coordinate spaces. Using the wrong one causes clicks/hovers to land in the
-wrong place.
-
-| Space | Used by | How to get |
-|---|---|---|
-| Physical pixels | `browser_click_coordinate` | `browser_coords` `physical_x/y` |
-| CSS pixels | `getBoundingClientRect()`, `elementFromPoint` | `browser_coords` `css_x/y` |
-| Screenshot pixels | What you see in the 800px image | Raw position in screenshot |
-
-**Converting screenshot → physical**: `browser_coords(x, y)` → use `physical_x/y`.
-**Converting CSS → physical**: multiply by `window.devicePixelRatio` (typically 1.6 on HiDPI).
-**Never** pass raw `getBoundingClientRect()` values to `browser_hover_coordinate` without
-multiplying by DPR first.
-
-## Screenshots
-
-Screenshot data is base64-encoded PNG. To view it:
-```
-run_command("echo '<base64_data>' | base64 -d > /tmp/screenshot.png")
-```
-Then use `read_file("/tmp/screenshot.png")` to view the image.
-
-Always use `full_page=false` (default) unless you specifically need the full scrolled page.
-
-## JavaScript Evaluation
-
-`browser_evaluate` wraps your script in an IIFE automatically:
-- Single expression (`document.title`) → wrapped with `return`
-- Multi-statement or contains `;`/`\n` → wrapped without return (add explicit `return` yourself)
-- Already an IIFE → run as-is
-
-**Avoid**: complex closures with `return` inside `for` loops — Chrome CDP returns `null`.
-**Use instead**: `Array.from(...).map(...).join(...)` chains, or build result objects and
-`JSON.stringify()` them.
-
-**For shadow DOM traversal with dynamic selectors**, write the full JS path:
-```js
-const s = document.getElementById('interop-outlet').shadowRoot;
-const el = s.querySelector('.msg-convo-wrapper');
-return JSON.stringify(el.getBoundingClientRect());
-```
-
-## Login & Auth Walls
-- If you see a "Log in" or "Sign up" prompt instead of expected
-  content, report the auth wall immediately — do NOT attempt to log in.
-- Check for cookie consent banners and dismiss them if they block content.
-
-## Efficiency
-- Minimize tool calls — combine actions where possible.
-- When a snapshot result is saved to a spillover file, use
-  `run_command` with grep to extract specific data rather than
-  re-reading the full file.
-- Call `set_output` in the same turn as your last browser action
-  when possible — don't waste a turn.
+Use for reading state inside a shadow root that standard tools don't
+handle, for one-shot site-specific actions, or to measure layout the
+tools don't expose. Do NOT use it on a strict-CSP site (LinkedIn,
+some X surfaces) with `innerHTML` — Trusted Types silently drops the
+assignment. Always use `createElement` + `appendChild` + `setAttribute`
+for DOM injection on those sites. `style.cssText`, `textContent`, and
+`.value` assignments are fine.
