From b339822b180f14bc3ef6aa74388d596949bc801b Mon Sep 17 00:00:00 2001 From: Duola <108492647+duolahypercho@users.noreply.github.com> Date: Sat, 15 Aug 2026 20:10:33 -0500 Subject: [PATCH 01/15] Model boundary: keep truncated tool arguments, and stop a moved router from reading as a missing field MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A `file_write` whose arguments the output cap cut in half came back as "missing required string path" — the model was sent to fix an argument it had spelled correctly. Three causes, all of them silent: - Unparseable argument text was thrown away (`unwrap_or(Value::Null)`) and reached the tool as an empty object. It is kept now as `ToolCall.unparsed_arguments` and refused before dispatch, with a message that tells a cut-off call apart from malformed JSON and names the cap. - `model.max_tokens` defaulted to 4096. One real source file is bigger than that, and on a reasoning model the thinking comes out of the same budget. Raised to 32768; a model whose own ceiling is lower now says so in its refusal and gets it (`rejected_output_cap`), so the raise cannot lock a smaller model out. - A provider that could not be reached said "model request failed for X" and dropped the cause. It now names the endpoint and the transport error, and for codex-router — where an OAuth user has no API key to fall back on — a connect refusal searches loopback for the gateway it moved to (4100 -> 4200 in 0.4.0-beta) and a 401 names the key file that rotated. Driven live on both provider paths: 26KB and 11KB single-call writes that the old cap could not have finished, the truncation refusal firing verbatim at a small cap, and a turn completing after core found the moved router itself.

Entries carry the kernel start time as well as the pid, because pids are recycled: a bare-pid ledger keeps vouching for a dead browser after the kernel reissues its number, and hands the agent whatever now owns it. On top of that boundary: `computer_targets`, `computer_doctor`, `computer_look`, `computer_type`, `computer_key`. `computer_click` and `computer_scroll` are built, measured, and withheld. Synthetic mouse events do not reach a background window by any route tried — CGEventPostToPid, CGEventPostToPSN, SkyLight's SLEventPostToPid, an SLPSPostEventRecordTo activation record, a primer click — while keyboard arrives through all of them, verified against a plain AppKit window that is never key. Shipping input that silently does nothing is worse than shipping none, so both stay under #[cfg(test)] with their failing live tests as the regression check. The current target is three.js and WebGPU, which live in the agent browser, so the playing tools are the browser ones: - `browser_play` holds keys while looking, because strafing is two keys at once and aiming while advancing is keys and mouse at once — neither is a sequence of single actions. It always releases what it held. - `browser_mouse_move` takes a delta and primes the origin first: Blink measures movementX against the previous position, so an unprimed turn arrives one step short and the error compounds. - `recordFrames` captures during the action. A screenshot taken after the keys come up is a picture of standing still. - `image_look` reads a contact sheet back, which nothing could do before. And a fix worth its own line: key events no longer carry nativeVirtualKeyCode. It was being given the Windows VK code, which is a different keycode space on macOS — 87 is keypad-5 — so every held key reached the page as Numpad5 and auto-repeated ~20,000 times in 600ms. A game keyed on e.code === "KeyW", which is the usual way, saw nothing. Holding W has probably never worked. Includes concurrent work from other sessions in agent.rs, browser.rs, tools.rs, rpc.rs, approvals.rs, config.rs, graph.rs and guardian.rs: the staged subset would not compile without it, having been verified by building the index in isolation rather than assumed.

It is not. **`CGEventPostToPid` is public API** and delivers events straight to +a target process without activating it and without moving the real cursor — the whole +no-cursor-steal property, on a supported call. The private SkyLight path buys *more +robustness*, notably background app dialogs where the public call does not land. That is a real +difference, and for a narrow target set it is an acceptable one. + +Every part we need is public API with a Rust crate already on crates.io: + +| Part | API | Crate | +| --- | --- | --- | +| Window capture, incl. occluded | ScreenCaptureKit (macOS 12.3+) | `screencapturekit`, `objc2-screen-capture-kit` | +| Element tree | `AXUIElement` | `accessibility-sys` / objc2 | +| Background input | `CGEventPostToPid` | `core-graphics` | + +Against that, adopting means redistributing and **re-signing a third-party macOS `.app`** inside +ours, tracking a 4,000-commit upstream, and adding **Swift** to a Rust + TypeScript repo — +because the Rust port is not at macOS parity (§4.1 caveats, still true). For roughly ten +actions, where cua ships 49. Not worth it. + +Consequence: §1.3 stops being the blocking measurement. Our own capture and input live inside +`cali-core`, which is spawned by the app and inherits its grants (§1.2) — there is no second +bundle to keep signed, so C′ and C″ both dissolve. + +### 4.1a The targets are game engines, and that inverts the design + +Decided use: three.js / WebGPU on the web now; **Unity, Godot and Unreal later**. That is the +roadmap, not a bet, and it settles two things the earlier draft got wrong. + +**AX is not the primary interface here.** Unity's editor is IMGUI, Unreal's is Slate, Godot +draws its own UI — all three are custom-drawn, which is precisely the sparse-or-empty +accessibility-tree case. A *running* engine build is worse still: one GPU surface, no tree at +all. So the `browser_snapshot`-style "text first, image second" ordering inverts. **Pixels and +coordinates are primary; AX is an opportunistic bonus where an app happens to expose one.** +This is structurally the same problem `browser_click` already solves for ``, and it +removes the most tedious component — AX tree walking — from the critical path. + +**Computer use here is primarily an eye, secondarily a hand.** Engine editors are all +scriptable (Unity C# batch mode, Godot headless CLI, Unreal Python and commandlets), and +scripting beats pixels for *driving* them. What scripting cannot do is answer "does it look +right", which is the question this repo is already built around — `baselines.rs`, +`capture_persist`, `video_analysis`, `image3d`. Capture is the feature; input is the smaller +half. + +**Open risk, and it is the sharpest one: raw input.** Unity's Input System and Unreal's raw +input read HID directly, and neither `CGEventPostToPid` nor the private SkyLight path is +guaranteed to reach them. Editors are AppKit-hosted and should be fine; *running builds* may +not be. This needs a per-engine spike before anyone promises the agent can play a native build, +and it does not affect capture at all — which is another reason to land the eye first. + +**Web games need none of this.** three.js and WebGPU run in the agent browser and are already +reachable by coordinate clicks on ``.

The control is a plain AppKit window that +never becomes key, writing to a file on `mouseDown`: + +| Route | Chrome | plain AppKit window | +| --- | --- | --- | +| `CGEventPostToPid` | no | no | +| `CGEventPostToPSN` (Carbon addressing) | no | no | +| `SLEventPostToPid` (SkyLight private SPI, `dlsym`) | no | no | +| keyboard, any route | **yes** | — | + +The decisive run puts all four routes and the keyboard control **in one process, one non-key +window, one measurement**: + +``` +target pid=20427 window=15803 bounds=(60,507,420,352) +after PID: posted=true events=[] +after PSN: posted=true events=[] +after SKYLIGHT: posted=true events=[] +after KEYBOARD: events=["keyDown:k"] +``` + +That single line of keyboard output is what makes the empty ones mean something. It rules out +four confounds at once: the target is alive and its logging works; it is not Chromium's trust +filter, because this is plain AppKit; it is not `acceptsFirstMouse` defaulting to false, because +the control overrides it to true; and it is not "the window simply was not key", because the +window is never key and the keystroke still arrived. + +Two earlier claims in this document were repaired by that control. The first diagnostic built +its three posts inside an array literal, so all three fired before any sleep ran and the +per-route attribution was meaningless. The second counted log *lines* including the target's +own `ready` marker, so zero clicks read as one. Both are why the run above prints the events +rather than a count. + +So it is genuinely background mouse delivery, not one hostile application. And **the private SPI +alone is not the answer either** — the symbol resolves and the call returns, and nothing +arrives. Per cua's own write-up the working recipe is three stages, not one call: two +`SLPSPostEventRecordTo` records to flip AppKit-active state without raising, a primer +`LeftMouseDown`/`Up` at `(-1, -1)` to tick the user-activation gate, and only then the real +click — with a `mouseEventSubtype` byte and window-local coordinate stamp whose values that +write-up does not publish. + +**All three implementable stages were then built and measured, and they still do not deliver.** + +| Stage attempted | Mouse arrives? | +| --- | --- | +| `CGEventPostToPid` — bare, then `+CLICK_STATE`, then `+WINDOW_UNDER_MOUSE_POINTER` ×2 | no | +| `CGEventPostToPSN` (Carbon addressing) | no | +| `SLEventPostToPid` (SkyLight private SPI, `dlsym`) | no | +| `+ SLPSPostEventRecordTo` activation record (yabai's `make_key_window` layout) | no | +| `+ primer click at (-1,-1)` | no | +| keyboard, throughout | **yes** | + +The activation record and the primer click are stages 1 and 2 of the published recipe, and both +were implemented from the open-source layout. What remains is the part cua describes but does +not publish: the `mouseEventSubtype` byte and the window-local coordinate stamp that mark an +event as a trusted user gesture. Without those values the record is incomplete, and no amount of +addressing fixes it. + +That is the end of what can be reached by inference. It is a reverse-engineering project against +undocumented byte layouts, not an afternoon. It +is the honest reason to reconsider **adopting cua for the input path only** while keeping our +own capture: they have already paid that cost, under MIT, and the split is clean because +capture and input share nothing but the ledger. + +`post_to_psn`, `post_via_skylight` and `click_via` are kept compiled under `#[cfg(test)]` — the +measurements are reproducible, and production carries only the route that works. + +`computer_scroll` was built, measured, and **withheld on that evidence** — shipping input that +silently does nothing is worse than shipping none. Its implementation stays compiled under +`#[cfg(test)]` as the executable record and the regression check. + +The click was tried three ways: bare down/up; with `MOUSE_EVENT_CLICK_STATE` set; and with both +`MOUSE_EVENT_WINDOW_UNDER_MOUSE_POINTER` and +`..._THAT_CAN_HANDLE_THIS_EVENT` naming the target window. None arrived. In every case the +frontmost application was correctly left alone — the events are being posted, they are simply +not being routed to a window the pointer is not over. + +This is the boundary of the public API, and it is exactly what the private SkyLight SPI exists +to cross — cua's own write-up on this is titled *how SkyLight enables multi-cursor background +agents*. §4.1 said "the private SPI buys more robustness"; it is more specific than that. +**It buys background mouse input, and nothing public substitutes.** + +So §4.1's "build our own" holds for capture, enumeration and keyboard, and does **not** hold +for clicking. Three ways out, and this is a decision to take deliberately rather than drift +into: + +1. **Private SkyLight SPI for the click path only.** Smallest surface — one call — but it + reintroduces exactly the maintenance tax §4.1 rejected, on an API Apple can change per + release. +2. **Activate the window, then click.** Public, reliable, and it steals the user's focus — + which forfeits the property that makes unattended `/loop` acceptable. Defensible only as an + explicit opt-in mode the user turns on while watching. +3. **Prefer per-target channels over OS-level clicking.** Chrome already has CDP, which is + strictly better. Unity, Godot and Unreal editors all have scripting bridges. Under this + reading, OS-level clicking is the fallback for apps with no channel at all, and the eye + (capture) stays the feature — which is where §4.1a already landed. + +`computer_click` ships reporting `delivered: "unconfirmed"` rather than claiming a success it +cannot observe, and its live test is kept failing-and-ignored as the regression check for +whichever option lands. + +**Still untested: whether the click lands when the window is frontmost.** Two attempts to force +Chrome to the front failed (the `osascript … to activate` never took), so the frontmost case has +been observed only incidentally, never controlled. It matters because it separates "the +mechanism is sound and only background routing is missing" from "synthetic mouse input does not +reach this app at all", and those point at different options above. Settle it before choosing. + +**Two defects found while measuring this, both now fixed:** + +- **Captures were squashed to a square.** `MAX_CAPTURE_EDGE` was applied to each axis + independently, so a 1280x800 window came back 1568x1568 — a distorted picture handed to a + vision model, and invisible in the bytes because it still decodes cleanly. Both axes now scale + by one factor, and `a_capture_keeps_the_window_aspect_ratio` asserts the ratio against the real + window rather than trusting the arithmetic. +- **The "focus was not stolen" assertion was vacuous.** It compared frontmost-app names obtained + by asking System Events over AppleScript, which needs an Automation grant this context does not + have and so returned `""` both times — `"" == ""` passes forever.

A window whose pid is not in the ledger is not +attachable, and `computer_attach` refuses with a reason. + +*Correction (2026-08-15): an earlier draft claimed "core already has that ledger". It did not.* +Spawns were scattered across `blender.rs`, `browser.rs`, `devserver.rs`, `mcp.rs` and +`diagnostics.rs`, each holding its own `Child` with no central record. `spawn_ledger.rs` now +supplies it, and it is built rather than assumed because a naive version is worse than none: +**pids are recycled**, so a ledger storing bare pids keeps answering "yes, that is our browser" +after the browser exits and the kernel reissues the number — handing the agent whatever now +owns it. Entries therefore carry the kernel start time and every lookup re-reads and compares, +so a recycled pid misses. Registration that never happens costs a refused attach; a stale entry +that matched would cost the invariant, so everything fails in the first direction — including +platforms where the start time cannot be read, where every lookup misses rather than degrading +to pid-only. + +Still outstanding: the spawn sites do not call `register` yet, so the ledger is correct but +empty. Wiring them is the next step, and until it happens attach scoping refuses everything — +which is the right way round to be incomplete. This makes "the agent read your email" *unrepresentable* rather than merely discouraged — the same construction as the approvals invariant ("only two things may produce a denial").

The index goes in the volatile tail of the prompt, never into `STATIC_SYSTEM_PROMPT`, which is the shared prompt-cache prefix. Reads are unguarded; `memory_write`/`memory_forget` are not, since they write outside any project and outlive the session. **Hooks** (`hooks.rs`) — `PreToolUse` runs ahead of the permission rules, the mode, and the guardian, because a deterministic rule the user wrote should not be re-litigated by a model. A hook can only ever add a block, never remove one. Every failure proceeds: a broken hook means a check did not run over a call the ordinary gate still sees, and failing closed would let one typo wedge a session. `PostToolUse` attaches its stdout to the tool result, which is where a post-write typecheck belongs. Spawned with `env_clear()` so no API key reaches a command that came out of a config file. **Commands** (`commands.rs`) — `commands/.md` whose body is the prompt. `$ARGUMENTS` and `$1..$9` substitute; an unfilled positional is left as written, because expanding it to nothing turns `costs $5.00` into `costs .00`. **`/loop` moved into core** (`loop_run.rs`) and gained profiles. The driver was ~400 lines in `AgentPanel.tsx` whose cancel flag was a React ref, so a loop died with the tab. `loop_start` now returns as soon as the run is registered and the driver continues detached; the panel only renders the `loop.*` events. The default profile replays the goal verbatim — the old driver rewrote it every iteration into a mandated three-root task graph, so "fix the typo in the README" was answered with a full production. The pipeline is intact as `--aaa`, and its completion defers to `loop_report::validate_completion_readiness`, the same gate a model calling `loop_report_update` must clear. Loop ids were minted from the millisecond alone; two runs started in the same one collided and the second silently replaced the first in the registry, so `loop_stop` reached the wrong run. Now suffixed with a sequence counter. The 30 pipeline tests in `AgentPanel.loop.test.tsx` run unchanged under `--aaa`. Driver behaviour moved to `loop_run`'s own tests, which drive a real run against a scripted in-process provider rather than mocking our own RPC layer.

Removal is a +swap-remove so the instance buffer stays densely packed and `count` alone bounds +what is drawn. + +**The simulation is fixed-timestep** (`engine/loop.ts`), decoupled from render. +Advancing the sim by the last frame's duration would make the city jump on a +dropped frame and produce different results on different machines. The +step budget per frame is capped so a backgrounded tab does not return and try +to catch up in one go. + +**Picking raycasts the ground, not the buildings** (`engine/grid.ts`).

The tests themselves carried no such gate, so `clippy --all-targets` on the Linux runner could not resolve `frontmost_app_name`, `click_via`, `mouse_events`, `post_via_skylight` or `scroll_by`. They are macOS-only by nature — the whole module is — so the gate goes on the tests. `reports.spec.ts` built a final iteration whose performance check was `skipped`. `validate_completion_readiness` requires a *passing* one, which is the point of "a run that never timed a frame cannot call itself done": the fixture described a report that can no longer reach `completed`. The fixture is what changed, not the rule — the rule is the intended behaviour and the fixture predates it.

Core registers the session's editor owner while handling that attach, so the tool call could arrive before an owner existed and hang until the 60s test timeout rather than failing with a reason. `requestfinished` fires once the response is back, which is the point at which the attach has actually been applied. The routing assertions are unchanged — this is synchronisation, not a loosened check. `reports.spec.ts`'s Checks metric is `checks_passed / (passed + failed + skipped)` (`refresh_totals`). Making the final performance check passed rather than skipped moves it from the skipped bucket to the passed one, so the header reads 5/6. "2h 35m" is unaffected: worked duration sums iteration durations, not check ones.
