162-167: 🧹 Nitpick | 🔵 Trivial

A note on the _generate_diff_image performance, Apprentice.

This nested pixel-by-pixel loop using getpixel is O(width × height) with Python-level iteration — it will be extremely slow on large screenshots. Consider using ImageChops or NumPy-based operations for the highlight overlay instead. This isn't a new issue introduced by this PR, so treat it as a future improvement.

🤖 Fix all issues with AI agents
In `@README.md`:
- Around line 220-243: The ASCII art for "AnimaWatch (FastMCP Server)" has
inconsistent right-edge alignment across rows (notably around the
"AnimaWatch"/"AppContext" header vs the Core Tools / Resources sections); update
the box so every line uses the same fixed width and matching border characters
(┌ ┐ └ ┘ ─ │) so the right column separators line up uniformly—for example, make
the outer box width consistent and reflow internal rows containing "AnimaWatch",
"AppContext", "Core Tools", "Resources", and the table rows (watch, screenshot,
recordings URIs, prompts) to that width to fix the misaligned edges.
- Around line 149-177: The markdown examples under headings "Test on Mobile
Device", "Compare Before/After", "Check Performance Metrics", "Analyze FPS",
"Multi-Model Consensus", and "List Available Devices" violate MD022/MD031/MD040;
fix each section by ensuring there is a blank line before and after the fenced
code block and by adding the language specifier "text" to each fenced block
(e.g., change ``` to ```text and add an empty line above and below the block) so
all six examples follow proper Markdown formatting rules.

In `@tests/test_server.py`:
- Around line 341-379: Duplicate test fixtures (mock_app_context and mock_ctx)
are present across TestTools and TestNewTools; extract them to a shared location
(e.g., tests/conftest.py) so both test classes reuse the same fixtures. Create
module-level fixtures named mock_app_context and mock_ctx that construct an
AppContext with mocked browser and vision (preserve AsyncMock for methods like
browser.record_interaction, browser.take_screenshot, vision.analyze_video,
vision.analyze_image) and return a MagicMock request context for mock_ctx that
sets request_context.lifespan_context to the shared AppContext; then remove the
duplicate fixture definitions from the test files so tests import the shared
fixtures automatically.
- Around line 436-471: Add happy-path tests for the functions currently only
covered for missing-context/errors: write async pytest cases that call
analyze_fps(video_path=...) with a small valid test video or a mocked filesystem
to return a known FPS result; call get_performance_metrics(url=...,
ctx=valid_ctx) with a real or mocked context to assert expected metrics; call
analyze_with_consensus_tool(url=..., ctx=valid_ctx) with a valid ctx and verify
the consensus output; and call compare_screenshots(url1=..., url2=...,
ctx=valid_ctx) with images or mocked image loads to assert the expected
comparison result; use the existing test patterns (pytest.mark.asyncio) and
provide/construct a valid ctx object or appropriate mocks for each function
(analyze_fps, get_performance_metrics, analyze_with_consensus_tool,
compare_screenshots) so the success paths and returned values are asserted.
- Around line 355-368: The current mock_pooled_context_cm being async returns a
coroutine so pooled_ctx calls __aenter__ on a coroutine (causing
AttributeError); instead make pooled_context return a proper async context
manager instance whose __aenter__ is an async function that returns
(mock_context, mock_page). Concretely: replace the async def
mock_pooled_context_cm / pooled_ctx combo with either a non-async factory that
returns an object AsyncCM (where AsyncCM.__aenter__ is async def and __aexit__
is async def) or use AsyncMock to return such an async context manager, then
assign that to mock_browser.pooled_context so get_performance_metrics and
compare_screenshots paths exercise the mock correctly.

- Add a blank line between each heading and its fenced block, and tag
  every bare fence as `text` (usage examples, "What It Does", the
  architecture diagram); blank line before the two JSON config blocks.
- Architecture box: nine rows were 77 columns wide against a 76-column
  border; trim the extra padding so every row's right edge lines up.

…happy paths

- Move the duplicated mock_app_context/mock_ctx fixtures from TestTools
  and TestNewTools into tests/conftest.py (plus a mock_page fixture).
- Fix the pooled_context mock: the old factory called __aenter__ on a
  coroutine (AttributeError) and returned a coroutine, not an async
  context manager. It is now an asynccontextmanager wrapped in a
  MagicMock, so `async with browser.pooled_context() as (_, page)` works
  and calls can be asserted.
- Mocked recording/screenshot paths now live under tmp_path, so tools
  that unlink them can never touch real files in /tmp.
- Add happy-path tests for analyze_fps, get_performance_metrics,
  analyze_with_consensus_tool and compare_screenshots (differences and
  identical pages), asserting arguments, rendered output, stored
  analyses and temp-file cleanup.

…etpixel

_generate_diff_image looped over every pixel in Python, calling getpixel
and draw.point. Build a threshold mask with Image.point and paste the
highlight colour through it instead; both run in C. Output is
byte-identical (1280x720: ~0.55s -> ~0.05s including the PNG save).

Regression test compares the generated image byte-for-byte against a
pixel-by-pixel reference, for opaque and translucent highlights, and
checks that a pixel exactly at the threshold is left untouched.

Update on this PR. All five inline threads have been answered with the fixing commit.

Review-body findings, point by point

  1. Outside diff range, src/animawatch/diff.py 162-167 (slow per-pixel getpixel loop in _generate_diff_image): fixed in c370ecc. The overlay is now built from a threshold mask (diff_gray.point(...)) and a single overlay.paste(highlight_color, box, mask). Both run in C. The output is byte-identical to the old loop, and a 1280x720 diff dropped from about 0.55 s to about 0.05 s, including the PNG save. The regression test test_diff_image_highlights_exactly_pixels_above_threshold compares the generated image byte for byte against a pixel-by-pixel reference, for both opaque and translucent highlights, and checks that a pixel exactly at the threshold is left untouched. I wrote it and saw it pass against the old implementation first. The now-unused ImageDraw import is gone.
  2. "Fix all issues with AI agents" block: it repeats the five inline findings, all answered on their threads (README: 4a23177; tests: 53c7dc7).

Consistency with the security PR (#33). #33 raises Pillow>=12.3.0 to clear the Pillow alerts. Pillow 12.x deprecates Image.getdata(), and this PR's getdata() → tobytes() change is the right fix for that: for an L-mode image it returns the same byte values on 10.x through 12.3. I merged this branch with fix/security-alerts locally. It merges cleanly, and pytest -W error::DeprecationWarning passes (166 tests) on the Pillow 12.3 lock.

Housekeeping. I converted this PR to draft before pushing. auto-merge.yml had enabled squash auto-merge on it back in February, and with CI now re-enabled it would have merged itself as soon as the checks went green and the threads were resolved. Merging is @rishitank's call, so mark it ready when you want it to go. Note that marking it ready re-runs auto-merge.yml.

Addresses the pre-merge Docstring Coverage warning (78.95% < 80%): the
only undocumented function this PR touches is the nested helper.

Locate the generated diff image straight after compare_screenshots and
run every result assertion inside the try block, so the finally clause
always removes the temp file.

Review of d7b2d4a:
- test_list_devices_by_category: the old check would pass for any output
  that mentions "mobile". It now requires the "**Category**: mobile"
  header, two mobile profiles (iphone_15_pro, pixel_8), and the absence
  of a tablet profile (ipad_pro_12) and a desktop profile
  (desktop_1080p).
- test_watch_with_device_valid: now also asserts that
  browser.record_interaction was called once with device="iphone_15_pro"
  (and the URL), so dropping the device argument would fail the test.

166 tests pass. Ruff check, ruff format --check and mypy src/ are clean.
