description	Use Peekaboo's live CLI and repo workflows for macOS desktop automation: screenshots, UI maps, app/window control, UIAX/action vs synthetic/CAEvent input paths, typing, menus, clipboard, permissions, MCP diagnostics, Inspector parity, and local validation. Use when a task needs current macOS UI state, direct desktop control, or changes to the Peekaboo repo.

Peekaboo

Peekaboo is a macOS automation CLI and agent runtime. Prefer the freshly built repo binary and canonical docs over copied command references; command surfaces move fast.

Start Here

In repo work, build/use the local binary:

pnpm run build:cli
BIN="$PWD/Apps/CLI/.build/arm64-apple-macosx/debug/peekaboo"
"$BIN" --version

Confirm permissions before automation:

peekaboo permissions status
peekaboo list apps --json

For the latest agent-oriented guide:
```
peekaboo learn
```
For the current tool catalog:
```
peekaboo tools
```
Find command docs:
```
node scripts/docs-list.mjs
```

Operating Rules

Use peekaboo see --json before element interactions so you have fresh element IDs and snapshot IDs.
Prefer element IDs from see for clicks and typing; use coordinates only when accessibility metadata is unavailable.
Check peekaboo permissions status before assuming a capture or control failure is a CLI bug.
Use --json when another tool or agent needs to parse results.
Respect the user's desktop: avoid destructive app/window actions unless requested.
If a command fails because the target UI changed, recapture with peekaboo see --json before retrying.
For repo fixes, add regression coverage when practical and update CHANGELOG.md for user-visible behavior.
see --json element bounds are screen coordinates; snapshot IDs are needed for stable element actions.
--no-auto-focus can prove background behavior, but synthetic clicks may be ignored by some apps until focus is allowed.
If a saved-snapshot UIAX/action click resolves in the wrong app, inspect snapshot windowContext preservation.

Common Workflows

# Inspect current UI and save JSON.
peekaboo see --json > /tmp/peekaboo-see.json

# Inspect a target app and extract useful IDs.
peekaboo see --app Calculator --json > /tmp/calc.json
ruby -rjson -e 'j=JSON.parse(File.read("/tmp/calc.json")); puts j.dig("data","snapshot_id"); puts JSON.pretty_generate((j.dig("data","ui_elements")||[]).map{|e| e.slice("id","label","identifier","bounds")})'

# Click an element discovered by see, with snapshot stability.
SNAP=$(ruby -rjson -e 'j=JSON.parse(File.read("/tmp/calc.json")); puts j.dig("data","snapshot_id")')
peekaboo click --on elem_42 --snapshot "$SNAP" --json

# Type into the focused field.
peekaboo type "Hello from Peekaboo"

# Launch/focus an app, then inspect its windows.
peekaboo app launch "Safari"
peekaboo list windows --app Safari --json

Input Path Testing

Peekaboo has two broad input paths:

UIAX/action path: accessibility actions such as AXPress, AXSetValue.
Synthetic path: pointer/keyboard events, commonly the CAEvent/CGEvent-style path.

Useful overrides:

# Confirm command exposes the override.
peekaboo click --help | rg 'input-strategy|actionOnly|synthOnly'

# UIAX/action click path from a saved snapshot.
peekaboo see --app Calculator --json > /tmp/calc.json
SNAP=$(ruby -rjson -e 'j=JSON.parse(File.read("/tmp/calc.json")); puts j.dig("data","snapshot_id")')
peekaboo click --on elem_8 --snapshot "$SNAP" --input-strategy actionOnly --json --no-auto-focus

# Direct accessibility action; good for proving UIAX independent of pointer events.
peekaboo perform-action --on elem_8 --action AXPress --snapshot "$SNAP" --json

# Synthetic click path; allow focus if you need visible app state to mutate.
peekaboo click --on elem_20 --snapshot "$SNAP" --input-strategy synthOnly --json

# Negative control: coordinates cannot use actionOnly.
peekaboo click --coords 10,10 --input-strategy actionOnly --json --no-auto-focus

Interpretation:

actionOnly success proves live AX re-resolution and action invocation.
synthOnly success proves coordinate resolution and event delivery, but verify app state independently.
perform-action AXPress is the cleanest UIAX smoke test.
Compare with Computer Use or another AX inspector when labels/descriptions differ.

Calculator Smoke Test

Calculator is a handy fixture because it exposes descriptions and identifiers.

BIN="$PWD/Apps/CLI/.build/arm64-apple-macosx/debug/peekaboo"
"$BIN" see --app Calculator --json --timeout-seconds 10 > /tmp/calc.json
ruby -rjson -e 'j=JSON.parse(File.read("/tmp/calc.json")); puts JSON.pretty_generate((j.dig("data","ui_elements")||[]).select{|e| ["Clear","AllClear","One","Two","Add","Equals","StandardInputView"].include?(e["identifier"].to_s)}.map{|e| e.slice("id","label","identifier","description","help","bounds")})'

SNAP=$(ruby -rjson -e 'j=JSON.parse(File.read("/tmp/calc.json")); puts j.dig("data","snapshot_id")')
"$BIN" perform-action --on elem_8 --action AXPress --snapshot "$SNAP" --json
"$BIN" click --on elem_19 --snapshot "$SNAP" --input-strategy actionOnly --json --no-auto-focus
"$BIN" click --on elem_20 --snapshot "$SNAP" --input-strategy synthOnly --json

Expected current behavior:

see --json includes bounds for each ui_elements entry.
Inspector/Computer Use should show Calculator descriptions/IDs such as One, Two, StandardInputView.
Snapshot-backed UIAX must use the captured app/window, not the frontmost app.

Repo Validation

swiftformat <changed-swift-files>
TOOLCHAIN_DIR=/Library/Developer/CommandLineTools swiftlint lint --config .swiftlint.yml <changed-swift-files>
swift build --package-path Apps/CLI
swift build --package-path Core/PeekabooUICore
swift build --package-path Apps/PeekabooInspector
swift test --package-path Apps/CLI --filter <TestName>
swift test --package-path Core/PeekabooAutomationKit --filter <TestName>

Notes:

If tests fail with no such module 'Testing', record it as local toolchain fallout; still run builds/lint/live smoke tests.
SwiftPM may warn about Commander identity conflicts; do not chase unless the task is dependency hygiene.
Build via pnpm run build:cli for normal CLI work; direct swift build --package-path ... is good for focused validation.

Keep this skill compact. Do not vendor generated command references here; update canonical CLI docs or Commander metadata instead.
