Add pi.registerToolRenderer((toolName, next) => renderers), which chooses the
renderers for calls to any tool, including tools that are not registered.
Resolvers run in extension load order; next() returns what the remaining
resolvers, then the registered tool, would use. Interactive mode and HTML
export both resolve through it.
The MCP extension uses it to render every mcp__<server>__<tool> call with the
MCP renderers, so calls in a resumed session no longer render fully expanded
before their server connects, or for good if it never does.

Kitty-protocol terminals only accept PNG. pi-tui now exposes
setImageTranscoder(); Image converts JPEG/GIF/WebP through it and shows
the text fallback without one. coding-agent registers a photon-based
transcoder, so images from extensions and all ToolExecutionComponent
hosts render.
closes#10292
Login and MCP sign-in screens show a copy hint and copy the URL to the
clipboard (OSC 52 over SSH). /mcp login in the TUI now uses the MCP
sign-in screen instead of a notification.
Replaces the 3D pi logo easter egg on header logo click. Armin's bitmap is
built from one cube per pixel, using the theme accent color. Regular mode
keeps the inline Armin art.
The top-level /login menu offers Sign in with Radius with its status,
with an animated shimmer on the Radius row and a short Radius intro.
After a Radius sign-in it offers to configure the Radius MCP server in
the global mcp.json with auth.provider and reloads. Cancelling a login
returns to the menu it was started from. OAuth sign-ins without a
subscription are labeled as accounts.

Palette colors now keep the bell-curve falloff and are
also capped at the palette color's OKLCH chroma times that falloff.
Lightness and hue are unchanged, so contrast is unchanged.

The user message's Markdown pads and colors its own background instead of
sitting in a Box that kept a second full-width copy of every line. The output
is identical.
Tools without a custom call renderer now show their arguments as key=value
pairs when collapsed and one key: value line per argument when expanded.
MCP tools get a server/tool title and results that collapse to 5 lines.
Built-in extensions (mcp, llama.cpp, codemode, tool-search) are now extension resources like files: the package manager resolves them as builtin:<name>, the extensions setting disables them with -builtin:<name> (per project too), pi config lists them, and --no-extensions turns them off unless loaded with -e builtin:<name>. They load after project trust is resolved and after file and package extensions.
Built-in extensions and tools are named builtin:<name> in errors, diagnostics, RPC source info, and bug reports.
Adds fullscreenWheelScrollLines ("auto" or 1-100). Auto keeps one line
per event in local macOS terminals and scales with wheel velocity
elsewhere, capped at six lines per event.

This adds codemode and MCP support to pi. Codemode (packages/codemode) runs
model-written JavaScript in a QuickJS wasm VM inside a worker. From there the
script calls pi's tools as async functions, uses a per-session store, and can
read the model catalog and run classifiers. The codemode tool in coding-agent
is compatible with Codex's exec tool, and codemode.mode works like Codex's
tool modes (on or only). Large results are written to a JSON temp file. MCP
(packages/mcp) is a standalone client for stdio and streamable HTTP servers,
with OAuth.
The core only gets general mechanisms; codemode, tool_search and MCP are
built-in extensions that use them. Other extensions can replace these
built-ins. Tools declare an exposure: direct, model-only, codemode, deferred
or hidden. prepareLoadout() lets an orchestrating tool change which tool
declarations the model sees. ctx.executeTool() runs nested calls through
validation and the tool_call/tool_result hooks. Those calls emit events with
parentToolCallId and are recorded as bounded nestedCalls on the parent
result, which compaction and HTML export use. Tools can also return
structuredContent with an outputSchema, and can report errors with isError
instead of throwing. MCP servers come from mcp.json (global, or per project
after the project is trusted) or from pi.registerMcpServer(). They are
managed with /mcp and pi mcp list|login|logout, and their runtimes load on
first use.
Closes#10040
Theme previews re-render the whole transcript, and streaming re-renders
every frame, so per-line and per-session work dominated in long sessions.
- visibleWidth: fast path for ANSI-styled ASCII, allocation-free escape scanning
- Box: compare unpadded child lines and skip a second width measurement
- Markdown: reuse parsed tokens across invalidation
- footer: cache usage totals and context usage per session state
- bash results: cache the collapsed preview including the expand hint
- sanitizeBinaryOutput: single regex replace
This adds experimental support for virtual models. A virtual model is a catalog entry that an extension registers with pi.registerVirtualModel(). It does not talk to a provider itself; for every request it picks a physical model and thinking level. The motivation is to make routing policies pluggable: plan on a strong model and implement on a cheap one, pick a model with a classifier, or move to a larger window when the context grows. Today this needs model switching by hand or hacks in prepareRequest.
The selection stays virtual: model_change records it, resume restores it, and each response records the physical model and thinking level that produced it. Router state can be stored on the session branch, so it follows /tree and forks and survives compaction. Context limits, compaction and image sizing use the physical model a request was routed to. examples/extensions/jev-router.ts shows a full router that uses the Jev classifier to pick Sol or Terra for planning and hands off to Luna after the first edit. docs/virtual-models.md describes the API.
Read Finder file URLs before icon image data on macOS. Quote paths in
bash mode and reject terminal control characters before rendering.
Fixes#9999

* feat(coding-agent,tui): add system theme derived from terminal colors
The new default system theme builds pi's colors from the terminal's reported foreground, background, and ANSI palette. Tokens take their hue and relative saturation from a palette slot; lightness is placed by OKLab lightness difference and WCAG 2 contrast minimums. Terminals that report only a background get built-in hues, and terminals that report nothing get ANSI indices with faint secondary text.
The TUI queries OSC 10, 11, and 4 in one burst ended by DA1, so replies complete in one round trip, and reports replies that arrive after the timeout. Startup never waits: the system theme starts in grayscale and updates when colors arrive. Light/dark detection now uses the reported colors instead of the ?996 query; mode 2031 notifications trigger a new query.
* fix(coding-agent): wait for terminal colors before building the startup header
The header and startup notices bake theme colors into their text. When the color replies arrived after they were built, as in Windows Terminal, they stayed grayscale. Startup now waits for the first color query, which ends at the DA1 reply or after 100 ms.
* fix(coding-agent): rebuild header and notices on theme changes
The startup header, loaded resources, and chat notices baked theme colors into their text, so they kept the old colors after a theme switch or when the system theme received the terminal's colors. They now use ThemedText, which rebuilds its text from a function whenever the UI is invalidated.
* fix(tui): keep focus on components that forward mouse events to children
A component that forwards a mouse event to a child it hosts, such as SettingsList with an open submenu, left keyboard focus on the child. When the host removed the child, focus stayed on a detached component and all keys were lost. The forwarding component now keeps focus, like delegating containers do.
* feat(coding-agent): describe the system theme in the theme selector
* feat(coding-agent): list the system theme above automatic in the theme selector
* refactor(coding-agent,tui): remove leftovers of the light/dark startup detection
Theme detection only reports dark or light now; the source and confidence fields only served saving the detected theme. The first-time setup no longer shows the detected appearance. Removes the TUI's unused queryTerminalColorScheme(), queryTerminalBackgroundColor(), queryTerminalForegroundColor(), and parseOsc11BackgroundColor(); queryTerminalColors() covers them.
* feat(coding-agent): match the reviewed system and light/dark theme design
The system theme now follows the reviewed design: color families with OKHSL saturation curves, palette slots per family, contrast rules per token and panel, relaxation for mid-gray backgrounds, and the terminal foreground for body text. Each contrast level is a target-lightness curve fitted to the reviewed output. The built-in dark and light themes use the reviewed Pi dark and light colors.
* feat(coding-agent): show the pi logo in the startup header
A two-line pixel logo replaces the app name. Its first line carries the version, its second line the first line of key hints.
* feat(tui,coding-agent): support OKHSL colors in themes
parseColor() accepts okhsl(H S L), and okhslColor() and colorToOkhsl() construct and read OKHSL colors. OKHSL saturation is relative to the sRGB gamut, so every value is in gamut. Theme files accept okhsl() values; HTML exports convert them to hex. The OKHSL code moves from coding-agent into pi-tui, where colors.ts now shares its Oklab conversion instead of keeping a second copy.
* refactor(coding-agent): write the built-in themes in OKHSL
The built-in dark and light themes use okhsl() values, with variables for colors that several roles share, so they read as color families and serve as editable templates. Near-identical values collapsed into one; no color changes visibly.
* refactor(coding-agent,tui): simplify terminal color and theme code
Share the terminal color query between startup and the theme controller, merge the query's resolve/late-reply state into one callback, keep a single global for terminal colors, use oklab.ts arrays directly in colors.ts, and drop leftover helpers and exports.
* fix(coding-agent): use one terminal light/dark decision everywhere
Theme pairs, the system theme, and Theme.appearance now share getTerminalTheme(): the reported background decides, then the terminal's light/dark report, then COLORFGBG, then dark.
COLORFGBG is classified by palette index like Vim (0-6 and 8 dark) and only reads the last field, so rxvt's "default" no longer picks up the foreground index.
Simplify the tests added on this branch.
* fix(ai): use an OpenRouter model that still exists in beta test
OpenRouter removed anthropic/claude-3-haiku, which broke type checking in CI after model regeneration.
Successful RPC prompt, steer, and follow_up responses include
data.disposition ("handled", "queued", or "started" for prompt), so clients
know whether to wait for agent_settled.

Expose theme colors as values and add theme.style() for combined styling.
- @earendil-works/pi-tui gains a Color type (palette index, sRGB, OKLCH) with parseColor(), mixColors(), colorToHex(), colorToRgb(), styleText() and related helpers.
- Theme JSON accepts #rgb and oklch(...) values and an optional appearance ("dark" or "light"), detected from the theme colors when omitted.
- theme.style() combines tokens or concrete colors with text attributes; theme.colors exposes concrete colors, including the terminal's reported default colors (OSC 10/11) for tokens set to "".
- Terminals with TERM=*-direct are detected as truecolor.
Make SessionManager projections authoritative for provider requests, add append-only context edits and actionable turn boundaries, and preserve existing queue scheduling during continuation and recovery.

This change makes system prompt text and tool changes part of the transcript rather than silently rewriting its starting conditions. This lets Pi record when instructions changed or tools became available, restore that state after resuming or navigating branches, and preserve cached prompt prefixes where the upstream supports it.
