The user's standing decision, never reviewed by anything. + **`deny` also removes the tool from what the model is sent**, so it is the + supported way to stop *paying* for a family, not only to refuse it: + `{pattern: "browser_*", action: deny}` drops 15 schemas — about 2,000 + tokens — from every turn. `ask` deliberately does not, or the approval card + would be unreachable. `agent::tests::a_deny_rule_removes_the_family_from_what_the_model_is_sent` + pins both halves. Bring a denied capability back as an MCP server when a + given project actually needs it. +2. **The floor** (`auto_floor`) — `project_revert` and untrusted `mcp__*` + always ask. Two entries, both decidable from the name alone, both wrong + things to be wrong about. +3. **The agent's own escalation** — every guarded tool's schema gains an + `ask_user` property in `auto` and only in `auto`. A model that fills it in + has decided this call needs the user; the string becomes the question on + the card. One-way: it can add a prompt, never remove one, and it is lifted + out of the arguments before dispatch so no tool sees a field it never + declared. +4. **The guardian** (`guardian.rs`) — a second, cheaper model reads the tool, + its description, the arguments, and the user's own words, and answers + `ALLOW` / `ASK` / `DENY`. + +Reads never reach layers 3 or 4, so a `file_read` costs nothing extra. + +Two properties of the guardian are load-bearing and easy to break: + +- **Tool results never enter its prompt.** It sees `role: "user"` turns and + the pending call. A file, a page, or an MCP server cannot argue for its own + approval. `recent_user_messages` is that boundary; do not widen it. +- **Every failure is `ASK`.** An unparsable reply, an outage, a missing key, a + reply that reasons its way to "…so ALLOW" — all of them ask the user. A + guardian that cannot answer degrades the session to Manual, never to Full + access. `parse_verdict` reads the first token only, for exactly this reason. + +Three consecutive guardian denials escalate the message the model gets from +"no" to "stop and tell the user". A human approval resets the tally. + +**Layer 0: hooks.** `hooks.rs` runs user-declared shell commands and sits +*above* all four layers — ahead of the `permissions:` rules, the mode, and the +guardian. The guardian is judgment; a hook is policy. A hook costs no tokens, +always runs, and cannot be argued out of its answer by anything in the +transcript, so a call it refuses should never reach a model that might be +talked into allowing it. Measured: a hook-blocked call makes **zero** guardian +requests. + +```yaml +hooks: + pre_tool_use: + - matcher: "file_write" # glob over the tool name, same matcher as permissions: + command: "~/.cali/guard.sh" # stdin: {hook_event_name, session_id, cwd, tool_name, tool_input} + timeout_ms: 4000 + session_start: + - command: "echo 'HOUSE RULE: this project ships only ES modules.'" + post_tool_use: + - matcher: "file_write" + command: "npx tsc --noEmit 2>&1 | head -5" # stdout lands on the tool result + stop: + - command: "~/.cali/keep-going.sh" # block to re-inject a prompt; top-level turns only +``` + +- **A hook may only add a block, never remove one** — there is no allow + verdict, the same one-way property the agent's `ask_user` escalation has. A + hook that could approve would be a config edit that silently widens Manual. +- **Block with** exit 2 (stderr becomes the reason) **or** stdout + `{"decision":"block","reason":"…"}` on exit 0, matching Claude Code so a hook + written for one harness runs in the other. Stdout is scanned from the first + `{`, so printing a log line before the verdict still blocks. +- **Every failure proceeds** — timeout, spawn failure, or a non-zero exit that + is not 2 is logged and ignored. The opposite of the guardian's fail-closed + rule and for the opposite reason: 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 the session with nothing to click. +- **`env_clear()` plus a six-key allowlist**, so no `CALI_*_API_KEY` reaches a + command that came out of a config file. `hooks::tests::secrets_never_reach_a_hook` + is the regression check. +- The tool *arguments* are on stdin, which is the whole point: a hook can tell + a `file_write` into the game's own `scripts/` from one into `~/.ssh`, which + is exactly the distinction a tool-name allowlist cannot make. +- **Global `~/.cali/config.yaml` only.** Project-scoped hooks are deliberately + absent until they carry first-use consent keyed on the command string — + checking out a repo must never silently acquire arbitrary code execution. + Copy the `approved_project_mcp` pattern when adding them. +- **`Stop` fires only for the top-level agent.** Subagents and graph nodes do + not, and that was measured rather than assumed: a hook written for the main + turn ("keep going until you say DONE") does not recognise a child's reply, so + it blocked every one and drove a single `subagent_spawn` through 199 extra + model calls. `stop_hook_active` tells a hook it is inside its own + continuation; the real bound is the turn budget, since every re-injection + spends a turn. This is the seam that lets an autonomous loop be a shell + script rather than harness code. +- **`PostToolUse` cannot block, only report.** The tool has already run, so a + refusal there would misdescribe the disk. Its stdout is attached to the + result as `hookOutput` — which is where a post-write typecheck belongs, since + the model needs that in the same turn rather than as an approval question. A + hook that exits 2 has its stderr attached like any other output, because a + failing check is exactly the case worth reporting. + +**Live coverage**, like `browser::tests::live` — CI cannot run it: + +```bash +cargo test guardian::tests::live -- --ignored --nocapture +``` + +It reads your own `~/.cali/config.yaml`, so it judges on whatever provider you +have. The assertions are one-directional on purpose: a real model's exact +verdict is not reproducible (the same `/etc/hosts` write has come back both +`ASK` and `DENY`), so what is asserted is only the direction that matters — +ordinary work must not stop the user, and the dangerous cases must not be +waved through. `the_ask_band_is_reachable` is the one that would catch the +worst regression: a prompt edit that collapses every risky call to `DENY` +leaves the user unable to approve anything, and the approval card unreachable. + +**Which model reviews.** The client sends `guardianModel` with the turn — the +cheapest priced model the active provider offers, from models.dev +(`reduceGuardianModels`). `approvals.guardian_model` in config stands in when +the client sends none; the session's own model reviews when both are absent. +Core holds no model literal, same rule as everywhere else. + +**Plan mode produces a document.** `plan_write` writes exactly +`/plan.md` — a constant, not a parameter, or the whitelist would be +admitting an arbitrary writer. `exit_plan_mode` takes the finished markdown, +is intercepted in `execute_tool_call` before the ordinary gate, and asks the +user: approve and the session moves to `auto` via an `agent.permission_mode` +event, or deny with a reason, which comes back as a failed call carrying what +they want changed. + +## Computer use + +`computer.rs` drives **native windows** — the ones `browser.rs` cannot reach because they are +not a web page. `spawn_ledger.rs` is what makes it safe. Note this is now the *third* thing +called "browser tools" in this repo's history: `editor_*` (the client webview), `browser_*` (the +agent's Chrome), and these. They are unrelated. + +- **The agent may drive only processes core itself spawned.** `spawn_ledger` records every + spawn — dev server, agent browser, Blender, MCP servers — and `computer_targets` is the whole + population. Anything else is refused, and the refusal names what is attachable instead. +- **Entries are a pid *and* the kernel start time**, because pids are recycled. A bare-pid + ledger would keep vouching for a dead browser after the kernel reissued its number, handing + the agent whatever now owns it. Every lookup re-reads the start time and compares. +- **What ships, works.** `computer_targets`, `computer_doctor`, `computer_look`, + `computer_type`, `computer_key`. `computer_click` and `computer_scroll` were built, measured, + and **withheld**: no synthetic mouse event reaches a background window by any route tried + (`CGEventPostToPid`, `CGEventPostToPSN`, SkyLight's `SLEventPostToPid`, plus the + `SLPSPostEventRecordTo` activation record and a primer click). Keyboard does arrive, verified + against a window that is never key. Both stay compiled under `#[cfg(test)]` with their failing + live tests as the regression check. +- **Capture is `CGWindowListCreateImage`**, deprecated in macOS 14 and working on 26.4. Chosen + because the ScreenCaptureKit wrapper crates build and link Swift, and shelling out to + `screencapture` would need a Seatbelt carve-out. It is one function, so migrating is contained. +- **Two macOS grants are required and both fail silently**: Screen Recording (or captures come + back blank) and Accessibility (or input posts and vanishes). They attach to whichever process + is *responsible* for core — the terminal under `dev.sh`, the app bundle when packaged, which + is why those two contexts differ. `computer_doctor` reports which, and proves capture by + capturing rather than asserting. +- **Today it has nothing to do, deliberately.** three.js and WebGPU games render in the agent + browser, where `browser_click` on the canvas already reaches them over CDP. Computer use is + staged for Unity, Godot and Unreal. `docs/plans/computer-use.md` carries the measurements. +- Live coverage is `#[ignore]`d and must run **serially** — `-- --ignored --test-threads=1` — + because each test launches Chrome against the same profile and two at once collide on its + `SingletonLock`, failing for a reason unrelated to what they measure. `computer::tests::live` + needs `CALI_BROWSER_HEADED=1`; the input diagnostics need the Swift control at + `core/tests/helpers/clicktarget.swift`. + +## The /loop profiles + +`/loop` takes a profile, and the default changed: it is now **`standard`**. + +| Profile | Invocation | What an iteration is | +| --- | --- | --- | +| `standard` (default) | `/loop ` | The goal, **verbatim**.

One constant, one line. + +**The driver lives in core** (`loop_run.rs`). `loop_start` returns as soon as +the run is registered and the driver continues detached, so a loop outlives the +request — and the tab — that started it: + +``` +loop_start {projectSlug, goal, profile?, intervalMs?, sessionId?, maxIterations?} +loop_stop {loopId} · loop_status {loopId} · loop_runs {} +``` + +- The RPC assembles the system prompt (so `default_system_prompt` and the + `SessionStart` hooks stay in `rpc.rs`); the driver owns only iteration. +- Tools are re-read every iteration, because an editor can attach or detach + mid-loop and a cached empty set would tell a connected editor's model it has + no scene. +- `Aaa` completion defers entirely to + `loop_report::validate_completion_readiness` — the same gate a model calling + `loop_report_update` must clear, so the loop cannot finish itself by a route + the report would have rejected.

With a session open only that session's run is adopted + (anything else would stream another chat's turns into this transcript); with + none open — the ordinary state after a reload, since `activeSessionId` is not + persisted — the project's run is adopted along with its session. Without this + the run kept working with nobody rendering it and the composer would start a + second one on top. + +**The panel only renders.** `AgentPanel.runLoop` calls `loop_start` and then +draws `loop.iteration` / `loop.done_refused` / `loop.completed` / +`loop.finished`; the run's own turns arrive as ordinary `agent.*` events +because the run reuses the panel's session. Stop is `loop_stop`, not a local +flag — a tab that closes no longer takes the run with it. + +Two consequences for tests: the browser never sends `agent_chat` for a loop, so +a spec cannot stub the model by intercepting `/rpc` (that is why +`e2e/loop-gate.spec.ts` now asserts the `loop_start`/`loop_stop` contract and +leaves the DONE gate to `loop_run::tests`); and driver behaviour is tested in +Rust against a scripted provider rather than through a mocked panel. + ## Extending without touching source - **Skills** — markdown + YAML frontmatter (`name`, `description`) dropped in @@ -214,6 +492,59 @@ the *client webview* tools (`editor_*`) "browser tools" — unrelated. command: the composer lists them beside the built-ins (tagged `SKILL`) and `/ ` sends a turn naming it, which the agent pulls in with `skill_load`.

Criteria must demand primary + evidence — files written, entities present, tests green, frames captured — + because unevidenced claims count as unmet. For a multi-domain game, use at + least three dependency-free Build roots (gameplay/entities, assets/visuals, + scripts/tests), then a separate Integration Build depending on every root, + and a terminal Judge depending on Integration.

JUDGE BLIND. The judge is a fresh critic that never sees how anything was + built and has no stake in it passing. It inspects the live artifact itself — + frames, scene state, test runs — and judges as a blind side-by-side against + the reference: "if these two screenshots were unlabeled, which would a + player pick, and why?"

Below threshold, only the failed item's builders re-run, + armed with the judge's punch list; passed items are left alone. Rejection + is the system working. The judge — never a builder — decides when an item + is done, and "done" means the score crossed the threshold, not "good + progress was made". If attempts are exhausted, report the graph as BLOCKED + with the last punch list — never present it as finished. If a graph ends + blocked, read graph_status, repair the stuck node's plan, and re-run. + +The acceptance criteria are the floor; the reference is the bar.

Prefer\n\ - a matching template's reference (template_list; ids below); else\n\ - pick the obvious genre flagship and tell the user which you chose; if the\n\ - genre is genuinely ambiguous, ask. If you cannot name the reference you are\n\ - matching, you do not yet understand the goal.\n\ -2. DECOMPOSE. Call graph_plan: small tasks, one owner each, explicit\n\ - acceptance criteria, dependency edges. Criteria must demand primary\n\ - evidence — files written, entities present, tests green, frames captured —\n\ - because unevidenced claims count as unmet. For a multi-domain game, use at\n\ - least three dependency-free Build roots (gameplay/entities, assets/visuals,\n\ - scripts/tests), then a separate Integration Build depending on every root,\n\ - and a terminal Judge depending on Integration. Never serialize independent\n\ - roots. Every plan ends in a judge node\n\ - carrying the named reference and a threshold (90 = would pass review at a\n\ - top studio; 100 = utterly perfect).\n\ - For a /loop run, call loop_report_start before graph_plan and append one\n\ - loop_report_iteration after every build/play/judge pass. Carry its\n\ - nextIterationMemory into the next pass; finish with loop_report_update.\n\ -3. FAN OUT. Call graph_run. Each node runs as a fresh subagent (planner,\n\ - coder, artist, tester, critic) owning only its own item — focused context\n\ - beats one overloaded transcript, and per-item quality beats averaged\n\ - quality: nothing weak may hide behind something strong.\n\ -4. JUDGE BLIND. The judge is a fresh critic that never sees how anything was\n\ - built and has no stake in it passing. It inspects the live artifact itself —\n\ - frames, scene state, test runs — and judges as a blind side-by-side against\n\ - the reference: \"if these two screenshots were unlabeled, which would a\n\ - player pick, and why?\" The 'why not ours' becomes the punch list. Harshness\n\ - is its job: finding flaws is success, approval without evidence is failure.\n\ -5. ITERATE PER ITEM. Below threshold, only the failed item's builders re-run,\n\ - armed with the judge's punch list; passed items are left alone. Rejection\n\ - is the system working. The judge — never a builder — decides when an item\n\ - is done, and \"done\" means the score crossed the threshold, not \"good\n\ - progress was made\". If attempts are exhausted, report the graph as BLOCKED\n\ - with the last punch list — never present it as finished. If a graph ends\n\ - blocked, read graph_status, repair the stuck node's plan, and re-run.\n\ -\n\ -The acceptance criteria are the floor; the reference is the bar. Pursue every\n\ -quality dimension the reference exhibits — lighting, materials, silhouette,\n\ -motion feel, feedback, readability, audio hooks — whether or not anyone listed\n\ -it. That surplus beyond the criteria is the difference between \"meets spec\"\n\ -and a result the judge is genuinely wowed by, and the loop runs until it is.\n\ +## The loop\n\ +- GOAL work runs a quality loop: name a world-class reference, decompose with\n\ + graph_plan, fan out, judge blind against that reference, iterate per item.\n\ + Load the `goal-loop` skill for the full procedure BEFORE calling graph_plan\n\ + or loop_report_start. Do not run it from memory — the thresholds, the plan\n\ + shape, and the blocked-graph rule are in the skill.\n\ \n\ ## Tools\n\ Project/state: project_list, project_open, project_checkpoint, project_revert,\n\ @@ -2254,6 +2413,7 @@ mod tests { sessions_root, agents: crate::agent::AgentManager::new(bus.clone()), graphs: crate::graph::GraphManager::new(), + loops: Default::default(), bus: bus.clone(), tools: std::sync::Arc::new(tokio::sync::RwLock::new(HashMap::new())), editor_bridge: crate::editor_bridge::EditorBridge::new(bus.clone()), @@ -2297,6 +2457,8 @@ mod tests { asking_session: "session-1", tool: "file_write", arguments: json!({ "path": "a.txt" }), + reason: None, + reason_source: None, }) .await })); @@ -2350,6 +2512,8 @@ mod tests { asking_session: "session-1", tool: "file_write", arguments: json!({ "path": "a.txt" }), + reason: None, + reason_source: None, }) .await }) @@ -2425,6 +2589,76 @@ mod tests { assert_eq!(result["version"], env!("CARGO_PKG_VERSION")); } + #[tokio::test] + async fn starter_list_offers_the_builtin_with_its_install_command() { + let projects = tempfile::tempdir().unwrap(); + let sessions = tempfile::tempdir().unwrap(); + let state = test_state(projects.path().to_path_buf(), sessions.path().to_path_buf()); + + let result = dispatch(&state, "starter_list", json!({})).await.unwrap(); + let starters = result["starters"].as_array().unwrap(); + let iso = starters + .iter() + .find(|s| s["id"] == json!("iso-city")) + .expect("the builtin starter is missing from starter_list"); + + assert_eq!(iso["scope"], json!("builtin")); + assert_eq!(iso["devScript"], json!("dev")); + // The client offers this command; core never runs it. + assert_eq!(iso["install"], json!("npm install")); + } + + /// A scaffold that does not end up attached is a folder the user has to go + /// and find, so the create arm opens what it wrote. + #[tokio::test] + async fn workspace_create_from_template_scaffolds_and_attaches_it() { + let projects = tempfile::tempdir().unwrap(); + let sessions = tempfile::tempdir().unwrap(); + let config = tempfile::tempdir().unwrap(); + // Without this the arm's persist_workspaces would rewrite the + // developer's own ~/.cali/config.yaml. + std::env::set_var("CALI_CONFIG", config.path().join("config.yaml")); + let state = test_state(projects.path().to_path_buf(), sessions.path().to_path_buf()); + + let target = tempfile::tempdir().unwrap(); + let dest = target.path().join("my-city"); + let created = dispatch( + &state, + "workspace_create_from_template", + json!({ "templateId": "iso-city", "path": dest.to_str().unwrap(), "name": "My City" }), + ) + .await + .unwrap(); + + assert_eq!(created["workspace"]["name"], json!("My City")); + assert_eq!(created["starter"]["id"], json!("iso-city")); + assert_eq!(created["install"], json!("npm install")); + // `describe` reads the scaffolded package.json, so this proves the dev + // script the manifest names actually reached disk. + assert!(created["workspace"]["scripts"]["dev"].is_string()); + assert!(dest.join("src/engine/city.ts").exists()); + + let id = created["workspace"]["id"].as_str().unwrap().to_string(); + let listed = dispatch(&state, "workspace_list", json!({})).await.unwrap(); + assert!( + listed + .as_array() + .unwrap() + .iter() + .any(|w| w["id"] == json!(id)), + "the scaffolded workspace was not attached" + ); + + // Scaffolding over the top of it would silently overwrite work. + let again = dispatch( + &state, + "workspace_create_from_template", + json!({ "templateId": "iso-city", "path": dest.to_str().unwrap() }), + ) + .await; + assert!(again.is_err()); + } + /// The terminal runs against the same tree `file_read` sees: a game with a /// folder attached runs there, not in CaliCode's project directory. #[tokio::test] @@ -3035,6 +3269,31 @@ mod tests { )]) } + #[test] + fn only_the_two_actionable_modes_add_prompt_text() { + // Manual and Full access are facts about the user's console, not + // instructions.

Starters: file trees CaliCode writes to disk to bring a new workspace into +//! existence. +//! +//! `store.rs` templates and this module answer different questions. A project +//! template is a *scene document* — entities, scripts, settings — and is the +//! right shape for something the three.js editor owns end to end.

An orthographic +camera gets the same look and lets the depth buffer do that work exactly. + +**The camera's polar angle is locked** (`engine/view.ts`). Free orbit turns an +isometric view into an ordinary 3D one, and every alignment the art relies on +stops holding. Azimuth is left free so the city can be turned. + +**Buildings are one `InstancedMesh`** (`engine/city.ts`). A `Mesh` per building +is a draw call per building; instancing draws the skyline in one. 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`).

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.

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.

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. Now read from + `lsappinfo front`, which needs no grant and returns a real ASN. ### 4.2 The four things CaliCode must own **1.

This repo already has three unrelated things called "browser +tools" (`editor_*`, `browser_*`, `computer_*`) and AGENTS.md has to spend a +paragraph untangling them; a fourth entry does not help. And the questions +these answer are about the *game*, not the transport — when the native path +(`computer.rs`, staged for Unity/Godot/Unreal) arrives, `game_perf` should +keep its name and change its backend, rather than acquire a `computer_perf` +twin that measures the same thing. + +## 3. `game_perf` + +``` +game_perf { durationMs?: 2000, budget?: boolean } +``` + +Returns: + +```json +{ + "frames": 118, "durationMs": 2000, + "fps": { "mean": 58.9, "p50": 60.0, "low1": 31.2 }, + "frameMs": { "p50": 16.6, "p99": 34.1, "max": 41.0 }, + "longFrames": { "over16ms": 12, "over33ms": 3 }, + "drawCalls": { "mean": 1840, "max": 2210 }, + "triangles": { "mean": 940000 }, + "heapMB": 214, + "api": "webgl2", + "budget": { "targetFps": 60, "verdict": "fail", "over": ["drawCalls", "low1"] } +} +``` + +**`low1` is the number that matters** and the reason not to just report mean +FPS.

Finds the largest `` on the page. +2. Re-acquires its live context: `canvas.getContext('webgl2') || + canvas.getContext('webgl')`. **Per spec, `getContext` returns the *same* + context object once created** — which is what makes this work with no page + reload and no cooperation from the game. +3. Wraps `drawArrays`, `drawElements`, `drawArraysInstanced`, + `drawElementsInstanced`, `drawRangeElements` to count calls and accumulate + primitives from the `count` argument. +4. Also wraps `GPURenderPassEncoder.prototype.draw` / `drawIndexed` — the + stated target set is "three.js and WebGPU games," so counting only WebGL + would silently report zero draw calls on half of them, which is worse than + reporting nothing. +5. Hooks `requestAnimationFrame` to timestamp each presented frame. +6. Resolves after `durationMs`, then **restores every original in a `finally`**. + A patch that leaks because the promise rejected leaves the game slower for + the rest of the session, and the agent would then be measuring its own + instrumentation. + +Engine-agnostic falls out of instrumenting the *graphics API* rather than the +engine: three.js, Babylon, PlayCanvas, raw WebGL and WebGPU all bottom out in +the same handful of draw entry points. Reading `renderer.info` instead would +have meant finding the renderer, which is exactly the problem `game_state` has +below. + +### The budget + +A per-project frame budget, in the project's `.cali/`: + +```yaml +budget: + targetFps: 60 + maxDrawCalls: 1500 + maxTriangles: 1000000 + maxHeapMB: 512 +``` + +`game_perf` compares and returns a verdict. This is the strategic half of the +tool: once a budget exists, `loop_report` can carry a perf line per iteration +and `validate_completion_readiness` can refuse a `completed` report that +regressed it — the same fail-closed shape the evidence gate already uses for +screenshots and scores. "Make it AAA" becomes "hold 60fps at this triangle +count," which is a target a loop can actually converge on. + +Absent a budget file the tool still returns raw numbers with no verdict. It +should never invent a target. + +## 4. `game_state` + +``` +game_state { name?: string, limit?: 50, offset?: 0 } +``` + +Returns entity transforms from the live scene graph — name, position, +rotation, scale, visible — plus the camera pose and entity count. Paginated +and compact-by-default, because the alternative is a 4000-entity dump into the +transcript. + +**This one needs the game's help, and that is the honest cost.** Under Vite or +any ESM bundle, `const scene = new THREE.Scene()` is module-scoped and +invisible from `window`. Resolution order: + +1. `window.__cali_game = { scene, camera, renderer }` — the convention. Our + project template sets it; one line. +2.

Generation cannot reuse that +path — see §3 — but it can reuse the config and key resolution around it. + +## 2.

It must not read as +a bug in the tool. + +## 3. The endpoint problem, stated honestly + +`model::chat` speaks `/v1/chat/completions`. Image generation does not. Three +shapes are in play: + +- **OpenAI-compatible `/v1/images/generations`** — OpenAI, xAI, and OpenRouter + accept it. Response carries `data[0].b64_json` or a URL. +- **OpenAI Responses API** — what `gpt-image-*` increasingly prefers, and what + `model.rs` already has a branch for (`chat_once_responses`). +- **Gemini native** — a different request body again, reached through + `generateContent` with an image-capable model. + +Do not paper over this with one adapter that "mostly works". Ship the +OpenAI-compatible shape first, because it covers OpenAI, xAI and OpenRouter — +which is every provider a user is likely to point at — and refuse an +unsupported one by name. A silent fallback that returns a text apology as if +it were an image is the failure worth designing against: the model would then +hand `image3d_mesh` a base64 blob of prose. + +A URL response must be fetched and stored, not stored as a URL. An asset that +points at a provider CDN is an asset that expires. + +## 4. Tool surface + +``` +asset_generate_image { + slug: string // project + name: string // asset name + prompt: string // what to draw + size?: string // "1024x1024" default; passed through, not validated + // against a hardcoded list — providers differ + transparent?: boolean // background removal where supported; ignored elsewhere +} + -> { assetId, name, mime, bytes, width, height, model } +``` + +`assetId` is the whole point of the return value: the next call is +`image3d_mesh { slug, assetId, mode }`, and the model should be able to read +that from the result without being told. + +**Access: `Guarded`.** It spends real money per call. That is not a formality — +it is exactly the class of call the Auto guardian is built to stop, and the +live guardian test already shows it asking `"this will spend credits to +generate the 3D hero mesh"` for the neighbouring tool. Classifying this +`ReadOnly` would let an unattended `/loop` spend without a prompt. + +`is_destructive` must agree. It answers from `core_tool_access` for core +tools, so declaring `Access::Guarded` in the literal is sufficient — but add +the assertion to `the_guarded_set_is_exactly_what_it_was` so the classification +cannot be quietly changed later. + +## 5.

Failure modes to design for, not discover + +- **No image model configured.** The default state here. Name both places to + set one; do not say "unsupported". +- **The configured provider has no image model.** `codex-router` today. Say + which provider, and that its catalogue has none. +- **Content policy refusal.** Surface the provider's own words.

CI cannot + run it, and it is the only test that proves the request shape is right. + +## 8. Open questions + +1. **Does the router proxy image endpoints at all?** It is down as of writing, + so this is unverified. If it does not, the practical path is a second + provider preset (OpenAI or xAI) used only for images — which the design + already allows, since `imageModel` carries `provider:model`. +2. **Library or mesh source?** `register_source_bytes` and + `asset_import_file` write to different places. Suggest: register for + meshing (the stated need), with a `library: true` flag later if wanted. +3. **Should the client show the image?** A generated asset the user cannot see + until it becomes a mesh is hard to judge.

Putting it there would also make +`auto` useless for building, which is the mode a `/loop` runs in. Layer 4 is +where it belongs, and the guardian is well suited to it: it already sees the +tool, its description, the arguments, and the user's own words, and it already +fails closed to `ASK` on anything it cannot parse. + +The layers above the guardian need nothing new either, and both are stronger +here than the guardian is: + +- **`permissions:` rules** glob over the tool name, so `shell_run: deny` is a + standing off-switch the user owns and nothing reviews. +- **`pre_tool_use` hooks** get `tool_input` on stdin — the actual command + string — and cost zero tokens, always run, and cannot be argued out of their + answer by anything in the transcript.

That is a weaker posture than + `hooks.rs`'s `env_clear()` + six-key allowlist, and correctly so — a hook is + a line from a config file, a build is the user's own project. +- **stdin null**, so a command that prompts fails instead of hanging forever + with nobody able to type at it. +- **Its own process group**, so the timeout reaches the whole tree. + +**Network is the one real design question.** The policy denies +`network-outbound` by omission, with a loopback carve-out so a dev server can +bind. That is right for `npm run dev` and wrong for `npm install`, which is +the single most valuable thing a shell unlocks. + +Answer: a per-call `network` argument, default `false`, that selects +`Network::Full` instead of `Network::Loopback`. Not a config flag and not a +blanket allowance — because an argument is *visible to every layer above*. The +guardian sees `network: true` in the arguments it judges. A hook sees it on +stdin. The approval card shows it. That turns "may this command phone home" +into a reviewable per-call fact instead of a global posture, and it means the +agent has to ask for the network rather than always having it. + +**Non-macOS is unconfined.** `sandbox.rs` is best-effort by design: no +`sandbox-exec`, no confinement, spawns go out bare.
