From ce87879587e10f430786971356cc8b7d11a7e444 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 10 Oct 2026 09:50:18 +0000 Subject: [PATCH 01/32] pi-ai: timestamps never repeat within a process now_ms returns a later time on every call, a millisecond ahead of the clock if need be, so a message's timestamp tells it apart from every other message the process made. Maple keys its timeline rows by it. Pi has no equivalent: its messages take the plain clock. This is a Maple-driven adaptation of the Pi crates, so it stays with the Maple integration until the owner reviews it; Maple could key its rows another way instead.

From: Claude Date: Thu, 8 Oct 2026 23:36:09 +0000 Subject: [PATCH 03/32] maple-agent: run tasks on the Pi crates, and switch the app to it The runtime crate is now built on pi-ai, pi-agent-core and pi-coding-agent. The Goose runtime moves to crates/maple-agent-goose, unchanged and still compiled, for side-by-side checks until it is deleted. What runs on Pi: - Maple's provider: Pi's Chat Completions provider over OpenSecret's encrypted transport, with Maple's catalog as Pi models. Every failure becomes one fixed Maple message per category, worded so Pi's retry and context-overflow checks classify it. The transport times out a response that does not start or stalls, so Pi's own request timeout is off. - Tasks: one JSONL session file per task in the account's owner-only folder, and a SQLite index of titles, state, web switch and settings that lists tasks while the runtime is stopped. - Runs: one per task, through one session factory. Pi's events become Maple's timeline rows, with ids that stay the same from the live rows to the reloaded ones. Stop keeps the reply so far and adds "Stopped by user". Messages sent during a run wait as chips and follow as one turn; steering joins the running turn. - Maple's read, edit and write tools as Pi tools. The account's MCP server list is checked and saved as before: names, commands, endpoints, environment variables and headers, and no new server under the computer use integration's name. Reads and saves of the account's settings take one lock, as they took Goose's runtime lock, so a save cannot overwrite a change made since its read. Features that have not moved yet answer from placeholders: running MCP servers, integrations, external agents, skills and slash commands, side models, image attachments and ACP. The app imports the new crate. Its Goose wording for compaction notices goes, since the Pi runtime never sends those strings.

Maple's own read, edit and write go; the timeline shows bash and powershell calls as Terminal rows. Maple sets up how their commands start, through bash's spawn hook: - the login shell's PATH, so an app opened from the Dock or a desktop launcher finds the tools the user's terminal finds. It is read once per process, from when the runtime starts, behind a marker so profile banners cannot be mistaken for it, bounded in time and output, and everything the probe starts is stopped; - the task's id as AGENT_SESSION_ID; - the task's tool context, so the ACP bridge's variables stay out. MAPLE_SHELL names the bash to run and replaces GOOSE_SHELL; the README says so.

Its code stays in history for the features still to move. With it go the Goose and Cua git dependencies (Cua returns with embedded CUA), 241 packages from the lockfile, and their Nix hashes. Every other package keeps its version; a few lose the features only Goose turned on. The README describes the runtime on the Pi crates and drops the note on the Goose pin, and the default log filter no longer names goose.

A file from a newer build is reported and left alone, and a choice of the retired standalone CuaDriver is dropped. - Codex and Claude Code are looked for on the login shell's PATH once it has been read, else on the app's own. Each version is read with a probe of three seconds and bounded output; a Codex older than 0.143.0 needs an update. Sign-in is reported but does not gate the switch. A probe runs in its own process session, which is ended afterwards, and on the PATH it was found on, so a script finds its interpreter there (Goose ran the version probe on the app's PATH). - An external agent can be switched on only while its CLI can run, and off at any time. Built-in CUA reads as not available until embedded CUA returns: it cannot be switched on, and its setup finishes nothing. Switching it on is refused while a custom MCP server has its name. - The choices are read and saved under the settings lock; detection runs before it is taken. What a choice does in a task moves with external agents and embedded CUA, and so do the skills Goose's runtime installed for external agents.

From 80c00f300d438139c569ed797816aa56d797d8f7 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 9 Oct 2026 02:40:16 +0000 Subject: [PATCH 07/32] maple-agent: the plan and questions tools on the Pi runtime Desktop tasks get Maple's todo_write and request_user_input again, with Goose's schemas, descriptions and results: - todo_write records the plan the user watches. The interface draws the list from the call, and the model gets it back, confirmed. - request_user_input asks one to three questions on a card and waits for the answers. A stopped run takes the card back, and an empty answer reads "(no answer provided)". As in Goose, a near miss does not dead-end the model: `questions` as one object, one question at the top level, missing or extra fields. Blank questions and options are dropped, ids made unique, and a card holds at most three questions of five options. The questions go through the broker of the service that started the runtime, which the interface answers, instead of the process-wide one Goose's tool clients had to reach for: a service built later, or a test running alongside, no longer takes another runtime's questions. ACP tasks get neither, as before. Errors read as Pi's tools' do, without Goose's "Error: " prefix.

The URL must use HTTPS, carry no credentials and name a public host: loopback, private, link-local, documentation and internal names and addresses are refused, embedded IPv4 included. - Errors are bounded to the same limits, and read as Pi's tools' do, without Goose's "Error: " prefix. As in Goose, a task's web switch decides whether the tools are offered, and a change takes effect from the task's next run. Desktop and ACP tasks both have one.

The answer is cleaned (reasoning blocks, quotes, control characters) and bounded like any title. - One-line summaries of a finished tool call or thinking block for the activity feed, from the same model, at most 100 characters. - /btw side questions: the task's model gets the task's context, then the side thread's earlier turns and the framed new question. The task's tools stay in the request, so the provider can reuse its cached prefix, but tool_choice is none. The answer streams as SideQuestion events and is not saved to the task. Titles and side questions end when the runtime stops; a request that times out is cancelled and drained, as Goose's were. The requests go through the runtime's model registry, so they take the same transport as the task's.

A URL must name a public host, carry no credentials, and answer within 30 seconds without a redirect, which could send the fetch to a loopback or cloud-metadata address. Files must be regular files. - At most 20MB, PNG, JPEG, GIF or WebP. An optional crop comes back as a PNG of the cropped rectangle. The result is a one-line summary and the image, which Pi then fits for the model as it fits every tool's images. - A task whose model cannot see images gets the image described instead: the tool takes a required context, and gemma4-31b describes the image for it, with thinking turned off in the request, as Goose sent it. A failed description says what was loaded and why it failed. Goose staged the image in a temporary file for its own image tool; the port decodes the bytes it read directly. The description's token usage is not recorded yet: that moves with the usage ledger. New dependency: image, already in the lockfile.

They load in every project, as in Pi. Goose's .goosehints is not read. - Skills: the account's, ~/.agents/skills, and in a trusted project .maple/skills and .agents/skills up to the repository root, as Pi reads them. The folders Goose's runtime read besides, ~/.claude/skills and ~/.config/agents/skills, and in a trusted project .claude/skills and .goose/skills, are Pi's extra skill paths, so they come after the user's own. The model sees each skill's name, description and file in the system prompt and reads the file with the read tool, as in Pi; Goose's load_skill tool is gone. - Prompt templates: the account's prompts folder and a trusted project's .maple/prompts. - Resources are read again at each run and a loaded session takes them through set_resources, so a skill or instruction file changed since shows from the next run, as Goose's skills did. Only the prompt sections that changed go out again. The composer's / list holds the skills, then the prompt templates whose names no skill has, with argument hints from a skill's frontmatter (top level or metadata, as Maple's bundled skills give them). A command expands into the skill's instructions as Pi's /skill:name does, with the arguments after them, or into the filled template; names match regardless of case. Resolving a command now takes the account, so the app passes it. Project trust covers everything a project adds besides its instruction files. The trust prompt asks when trusting would add a skill or template that does not load now, or a .maple/SYSTEM.md or APPEND_SYSTEM.md, and names which (two new protected features). Before, it looked only for .agents/skills/**/SKILL.md, and the / list offered and ran an untrusted project's skills, which the model's load_skill refused; now an untrusted project's skills are neither listed nor run. The README describes where instructions, skills and templates come from, and its file table drops the Goose rows: task sessions and their index are in the account's sessions folder, and the account's skills folder replaces the Goose one, where the delegation skills will go when external agents return.

They are stored with the task as before: owner-only, PNG, JPEG or WebP, at most ten per message and 10MB each. - The model gets what the user typed, then each image's name and maple-attachment source, as Goose's runtime wrote them. A model without vision is told to look with read_image, which reads the task's attachments. A model with vision gets the images beside the text; unlike Goose's runtime, its text names their sources too, so read_image can crop one. - A message sent during a run waits as a chip with its images, steering carries them, and a stopped run puts its unsent messages back with theirs. A message Pi had already taken for steering comes back with its images by source only. - The timeline shows what the user typed with the images, live and after a reload, read back from the message itself, so no other record is kept. The interface draws them from the task's attachments. - A task is named from its first message with text; images alone do not name it.

Maple starts a stdio server itself, so it can stop it as Pi does; a Streamable HTTP server is reached through reqwest. Which servers a task has is saved with the task, by name: a new task gets those switched on in Settings, or exactly the ones the composer names, and the composer's menu switches them per task. A task runs the servers' current settings, so an edit applies from its next run, and no secret is copied into the task. A chosen server that is no longer configured stays listed, switched on and unavailable, and can only be switched off. The servers start with the task's run, in the background, and the run waits up to ten seconds for them before its first prompt, as Pi's first prompt does; one that connects later joins from the next prompt. Their tools reach the model as mcp____, with the server's descriptions and schemas, and their results as text and images, long text cut in the middle with the whole saved to a file. Tool list changes are read again, and a dropped connection opens again on the next call. As in Pi, a tool is never taken from the session: one the server withdrew, or of a server switched off or stopped, stays, and calling it fails with Pi's words until the server offers it again. The connected servers' instructions join the system prompt. A server that fails to connect is named in the run's notice with Maple's wording, once, and is tried again at later runs without holding them up. Switching a server on for a loaded task connects it at once and keeps it off with the reason when it fails. A stdio server runs in the task's folder with the login shell's PATH and its environment variables, in its own process group, and stops by its input closing, then SIGTERM, then SIGKILL to the group, which also ends what it started; a failed start shows the end of its error output. An HTTP server's URL and header values take $NAME and ${NAME} from its environment variables, and redirects are not followed. Calls time out by the server's timeout, which progress resets, and Stop tells the server the call was cancelled. The servers live with the task's loaded session and stop when it shuts down; the four idle tasks used last keep theirs. MCP tool rows read as "server: tool". A fake Streamable HTTP server in the tests drives rmcp's client for real: the handshake, calls, progress, cancellation, timeouts and tool list changes, and three runs end to end, among them a withdrawn tool and a server switched off, whose tools stay and fail.

It now asks the runtime, which counts the task's context as Pi does: the last reply's reported usage, plus an estimate of what came after it, which also covers a compaction. A loaded task counts its live session; any other task, its session file, which a test checks gives the same count. A task with nothing in it yet has no count, as before. The limit still comes from the model catalog or MAPLE_CONTEXT_LIMIT. The app drops its read-only handle on Goose's sessions database. The ledger had no other reader: side-model and image-description usage was recorded there only for it.

The Codex app-server client, the Claude Code stream-json client, and the host that runs them (activity, approvals, questions, Stop, process groups) are the Goose runtime's, with its Goose types replaced: - The tools are Pi tools every desktop task has. A run declares them only while the task may use a provider: one switched on in Settings and for the task. The task's choice is saved with the task, as `externalAgents` in its settings, and its MCP menu lists the agents switched on in Settings, as before. - A turn's progress repaints the row of the tool call that started it. The tool finds that row from the reply Pi stored before running it. - A background turn's result reaches the model as a custom message the user does not see. Maple keeps it out of sight in the task's queue behind a running turn, sends it as a turn of its own, or starts a run for it. A run stopped before it went leaves it in the task's history for the next message, as Goose wrote it to history on Stop. - The turn's end is a session entry the transcript projects back onto the call's row, so a reopened task shows what the agent did, followed by a notice. A task reopened while a turn runs shows the row as it stands, and the row above the composer and its Stop button come back. - Deleting a task, stopping the runtime or signing out ends its agents without a report. - The /handoff, /committee and /advisor skills go into the account's skills folder, which Pi reads, while an agent is on in Settings. One change from Goose: an agent whose command could not start no longer keeps one of a task's four places. The driver tests run the Goose runtime's fake Codex and Claude Code CLIs. New end-to-end tests run them under the runtime with a scripted model.

Maple tells you when the agent finishes, in + this turn or the next. Continue with other work meanwhile. +5. When Maple reports the end, call `agent_status` once, read the changed + files yourself, and verify the acceptance criteria before you rely on + them. If more is needed, call `agent_send` with the same `agent_id` so + the agent keeps its context. + +Agents take time.

What the Goose runtime did, on Pi: - Each run binds a task that has CUA on to its own account-and-task scoped CUA session anew, which renews its authorization, and registers the catalog's tools on the task's Pi session as cua-driver__, with the instructions in a prompt section. The lifecycle tools and every session argument stay hidden. The binding happens beside the MCP servers' start, and a failure is named in the same notice, as "Computer use (CUA)". The binding closes with the task's session, or when CUA is switched off for it; the tools stay, as in Pi a tool is never taken from a session, and calling one fails until the task is bound again. - Every model gets the observation's structured grounding as bounded, image-free text; a model without vision, read from the run's model, gets each screenshot described by the side model in its place. - A task's choice is saved with it, as computerUse in its settings. A new desktop task records one once CUA is set up on the device: on when the composer names it, or else the default for new tasks. The MCP menu ends with CUA's row, and switching it on binds a loaded task at once. - The Integrations card reads the device's permissions, the GNOME helper's state and the SDK version; setup asks for the permissions on the click's thread and installs the helper where it is missing. Pi fits a screenshot like every tool image (2000 pixels, 4.5MB), with its note on mapping coordinates back; Goose sent screenshots as captured. Helper usage is not recorded. The unit tests are Goose's, on the new types; the SDK's own runtime runs the lifecycle test. An end-to-end test covers the switch, the row and new tasks' choice, and, where CUA can run, a real binding's tools, which fail once CUA is switched off.

The runtime gains what a calling surface needs, in agent::surface: - A lease holds each task a connection drives. While it lasts, the task's session is built with the lease's tool context (the bridge's allowlisted variables), the desktop's own tools stay out of it (the plan, questions, external agents and computer use), and the client's HTTP MCP servers run beside the task's, in place of a saved one of the same name. The desktop cannot send to a held task. Releasing revokes the context, stops the task's run and unloads its session. - `send_surface_message` runs a prompt as a run of its own, after any run the surface stopped has ended, with events for the caller alone; the prompt's cancellation stops the run from its setup on. - A task created over ACP is provisional until its first prompt: lists leave it out, and closing it untouched deletes it. A runtime start removes provisional tasks a crash left behind for more than ten minutes. - The caller's system prompt follows Maple's own for the tasks it creates, for as long as the runtime runs. - Trust asked over ACP is saved for the session's project, and the task's session is built again with it. How a turn reaches the client on Pi: text and thinking stream as they come, and the row that settles a message sends only what did not stream; a tool call is announced with its kind, which result updates keep. A failed reply is told when the run ends failed, since Pi may still retry it. Runs now publish `Compacting` and `Compacted`, which the client sees as the reference adapters' notices; the desktop ignores them and reloads on `HistoryReplaced` as before. `usage_update` counts the task's context as Pi does rather than the turn's tokens. `/compact` on a history too short to summarize says so instead of failing. The dispatcher no longer waits on slow requests: prompts are admitted in order, so a `session/cancel` right behind one finds it, and everything else about them, close, load and config changes run in the background. The ported unit tests run unchanged where the shapes did; stdio tests on the scripted provider cover a full turn and its replay, cancel, a failed turn, /compact, images through read_image, the trust prompt, and Buzz's fields; runtime tests cover leases, provisional tasks, the bridge context reaching a command, a client's MCP server, and the startup sweep.

They are pinned back, so every package those two commits added is one the shipped lockfile had, at its version.

Goose's runtime answered such a read with the way to a description: the file is an image, to inspect with `read_image`. A Pi extension of each task's session answers so again, through Pi's `tool_result` rewrite, while the session's model cannot see images; a model with vision still gets the image, as in Pi. The prompt of a model without vision carries Goose's line again: "Use read_image when you need to inspect an image." `read_image` was set up for the model its session was built with, and a task loaded for a side question or `/compact` is built without vision, so a run on a model with vision could get descriptions in place of images, and the reverse images it cannot see. The same extension sets it up again on Pi's `model_select` when the model's vision changes. It now resolves a local path as `read` does, macOS screenshot names included, so the path `read` answers with opens. Images in MCP servers' results still reach a model without vision as the provider's note that it does not accept images. Both run end to end on the scripted model: `read` on an image for a model without and with vision, and `read_image`'s schema for runs that can and cannot see after a load without vision.

Neither host sent the window, so every run compacted at the 128,000-token default, whatever the catalog gives the model. ACP also looked up vision only for a prompt with images, as it did under Goose, so a vision model ran as one without vision on every other turn: `read` sent it to `read_image`, which described images it could see. The runtime now answers one catalog lookup with both, `model_catalog_entry`. ACP looks it up on a session's first turn and keeps it until the model changes, and sends both with every turn. Its `usage_update` reports the same window. The desktop keeps each model's entry where it kept vision and sends the window with each message. The context ring already showed the catalog's window; compaction now agrees with it. A model the catalog does not describe, or a catalog that cannot be read, still runs without vision and on the default window. ACP asks again on the next turn. The ACP server runs a turn without images on a catalog that marks the model with vision and a 64,000-token window. The run's model sees images and has that window, `read_image` needs no context, and `usage_update` reports 64,000. The runtime's lookup gives a listed model's entry, an empty one for a model the catalog does not list, and none while the catalog cannot be read.

Master's app does the same. The parked chat now gets the events too, as it already gets the update banner. It only updates its own state from them. Found in live validation. The window code has no test harness; Maple Agent CI builds it.

Any Maple code or extension with the registry can classify with it. As Pi's classifier requests do, a request the server fails or asks to wait is sent up to two more times. The transport sends Pi's System One requests to /v1/systemone, where it sent only chat completions before, and asks for a JSON reply there. A failed reply keeps Maple's fixed message, as for chat, so System One's error carries no part of the server's body. Responses now carry their headers, names in lowercase, as Pi's transports give them: Pi's response hook sees them, and a classifier retry follows the server's retry-after or x-should-retry. Chat requests still send nothing again themselves, so headers change no retry there. Nothing in Maple classifies yet. A result carries its own usage, for the feature that asks to report: the server counts what Maple bills, and a run's usage counts its replies.

A client's stdio MCP server is now always refused. - The tool context those variables travelled in, with its scrubbing of `BUZZ_*` from every task's commands and external agents, its revocation and its launch fence. A lease still ends its hold at once when it is released, and an ACP task's commands keep the PATH the client started Maple with, as they did through the context. - `session/new`'s `systemPrompt` and `_meta.sessionTitle`, and the runtime's per-task system prompts. ACP tasks are named from their first prompt, as desktop tasks are. - Protocol version 2, which told Buzz that `session/new` takes its `systemPrompt`: `initialize` answers with the latest stable version, 1. - The count of connections that carried Buzz's credentials. The README's ACP section, the external agents doc and the scenario checklist drop Buzz, and two errors no longer name a tool context.
