 MODEL: GPT-5.3-codex
-REASONING: low
+REASONING: medium
 
 COMMAND:
-Correct the Asteroids sample launch targets only.
-Ensure the card uses exactly:
-- /games/Asteroids/index.html
-- /games/Asteroids/index.html?debug=1
-
-Do not reference asteroids_new anywhere.
-Do not change other samples, asset files, or layout.
-Update roadmap status only if this execution is test-backed and appropriate.
-Write validation findings under docs/dev/reports.
+Create BUILD_PR_TOOL_HOST_SEAMLESS_IFRAME_PARITY.
+
+Refactor Tool Host so opening a tool in host feels visually equivalent to opening the tool directly, except for compact host controls/help inside the collapsible imported section.
+
+Requirements:
+- iframe-hosted tool should use the available workspace as if opened directly
+- remove obvious host chrome/wrappers that make hosted mode visibly different
+- keep Tool Host HTML minimal
+- host-specific UI should live only in the collapsible imported section
+- collapsing that section should make the hosted tool appear nearly identical to direct launch
+- optional small fullscreen button is allowed, but do not depend on browser fullscreen as the main solution
+- preserve Open In Host behavior
+- preserve direct launch behavior
+- no inline styles
+- no embedded style blocks
+- no JS style-string injection
+- no color/token changes
+- no unnecessary per-tool hacks

-Correct Asteroids sample play/debug links to existing game path.
-Remove incorrect target usage that referenced nonexistent asteroids_new assets.
-Scoped fix only.
+Refactor Tool Host iframe presentation for near direct-launch parity by removing host chrome wrappers,
+keeping host controls inside the collapsible imported section, and eliminating JS/inline style injection.

 # Validation Checklist
 
-- [ ] Asteroids Play link resolves to /games/Asteroids/index.html
-- [ ] Asteroids Debug link resolves to /games/Asteroids/index.html?debug=1
-- [ ] No asteroids_new reference remains in the Asteroids sample link target
-- [ ] No other sample cards changed
-- [ ] No duplicate Asteroids launch links
+- [x] Hosted tool workspace feels near-identical to direct launch
+- [x] Tool Host does not present obvious extra page chrome around the iframe
+- [x] Host-specific controls/help exist only in the collapsible imported section
+- [x] Collapsing host controls leaves the hosted tool visually close to direct-open mode
+- [x] Open In Host still loads tools correctly (selector and runtime mount flow preserved)
+- [x] Direct tool launch still works (manifest launchPath behavior unchanged)
+- [x] Any fullscreen button is optional and non-essential (none added)
+- [x] No inline styles or embedded style blocks added
+- [x] No JS style-string injection in Tool Host runtime/main

+# BUILD_PR_TOOL_HOST_SEAMLESS_IFRAME_PARITY
+
+## Purpose
+Refactor Tool Host so hosted tool presentation is nearly identical to direct-launch presentation, with host-only controls/help contained inside the collapsible imported section.
+
+## Scope
+- Keep Tool Host HTML minimal.
+- Move host-specific controls into the collapsible imported section.
+- Remove host chrome wrappers around hosted iframe workspace.
+- Keep hosted tool workspace full-width/full-height in normal page flow.
+- Preserve `Open In Host` and direct launch behavior.
+- Enforce no inline styles, no embedded style blocks, and no JS style-string injection.
+
+## Exact Targets
+- `tools/Tool Host/index.html`
+- `tools/Tool Host/main.js`
+- `tools/Tool Host/toolHost.css` (new)
+- `tools/shared/toolHostRuntime.js`
+- `docs/dev/codex_commands.md`
+- `docs/dev/commit_comment.txt`
+- `docs/dev/reports/validation_checklist.txt`
+
+## Implementation Status (Execution-Backed)
+- `[x]` Host controls moved into collapsible imported section in `tools/Tool Host/index.html`.
+- `[x]` Host workspace simplified to iframe mount surface with no panel wrapper chrome.
+- `[x]` Runtime iframe style injection removed from `tools/shared/toolHostRuntime.js`.
+- `[x]` Link disabled state moved from JS inline styles to CSS class in `tools/Tool Host/main.js` + `tools/Tool Host/toolHost.css`.
+- `[x]` No inline style attributes in Tool Host HTML target file.
+
+## Validation Executed
+1. `rg -n "style\." "tools/Tool Host/main.js" "tools/shared/toolHostRuntime.js"`
+   - Result: no matches.
+2. `rg -n "<style|style=" "tools/Tool Host/index.html"`
+   - Result: no matches.
+3. `rg -n "data-tool-host-(select|state-input|mount|prev|next|unmount|standalone|switch-meta|status|current-label|mount-container)" "tools/Tool Host/index.html"`
+   - Result: expected host control and mount selectors present.
+
+## Notes
+- No color/token changes were introduced.
+- No per-tool hacks were introduced.
+- Tool Host-specific UI remains inside the collapsible section; collapsing it leaves a near-direct hosted surface.
