docs: bring README in line with current tools and requirements - #71
The README had drifted from the code. This updates it to match:
Tool count: 56 → 79 (counted from @mcp.tool in gimp_mcp_server.py). Added the 16 undocumented tools to the tables, including new Batch & Multi-Format Export, History, and Connection & Raw API sections: undo, redo, save_xcf, set_active_image, convert_color_mode, crop_to_selection, warp_region, batch_export, batch_resize, export_web_optimized, export_icon_sizes, export_social_media_kit, export_sprite_sheet, check_server, restart_server, call_api
Test count: 56 → 58 (run_tests.py); listed the regression tests under tests/
Python: 3.8+ → 3.11+ to match requires-python in pyproject.toml
Troubleshooting: menu path corrected to Tools > MCP > Start MCP Server
Future Enhancements: removed "Undo System" since undo/redo already exist
Not addressed
pyproject.toml declares license = "MIT" while LICENSE and the README badge are GPLv3. That needs a maintainer decision, so I left it alone.
Test plan
Render the README on GitHub and check the tables and links
Updated the documented tool count to 79, test results to 59/59, and minimum Python version to 3.11.
Expanded the tool catalog with color-mode conversion, selection-based cropping, region warping, active-image selection, batch and multi-format export, undo/redo, and connection and raw API tools.
Added two test-script entries and updated troubleshooting guidance to include the GIMP Tools > MCP submenu.
Removed Undo System from the Future Enhancements list.
- Tool count 56 -> 79; document the 16 tools missing from the tables
(undo/redo, save_xcf, batch/export helpers, warp_region, call_api, ...)
- Test count 56 -> 58; list the regression tests under tests/
- Python requirement 3.8+ -> 3.11+ to match pyproject.toml
- Fix troubleshooting menu path (Tools > MCP > Start MCP Server)
- Drop "Undo System" from Future Enhancements (undo/redo exist)

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Add blank lines before the new tables.
markdownlint-cli2 reports MD058 at these lines because each table follows its heading without a blank line. Add one blank line after each new section heading.

Match the documented test total to run_tests.py.
run_tests.py counts 58 t() calls plus the select_color_nonemptychk() call. A clean run therefore prints 59/59 PASSED, not 58/58. Update both documented totals, or stop counting the extra check. (raw.githubusercontent.com)

Do not claim that this suite verifies all tools.
The runner exercises only a subset of the catalog. It does not call tools such as convert_color_mode, crop_to_selection, or warp_region. Replace “verify all tools work” with “verify selected tools,” or expand the runner. (raw.githubusercontent.com)

Thanks, this is a careful update. I checked it against the code: the 79 tools (@mcp.tool count, and all 16 new entries exist), Python 3.11+ (requires-python), and the Tools > MCP menu path are all correct. Leaving the license mismatch alone is right; that's #49.
One thing to fix before merging: the README now presents some tools as working when they're known to fail on GIMP 3.2:
undo / redo crash (#42). #53 found that GIMP 3.2 gives plug-ins no way to undo/redo at all.
Keep the new tables, but mark these tools, e.g. "⚠️ broken on GIMP 3.2, see #42".
Keep Undo System under Future Enhancements, since it's still a missing capability.
"All GIMP 3.2 API breaks fixed and tested" overstates things; the test suite doesn't cover these tools. Maybe soften it, e.g. "most GIMP 3.2 API breaks fixed; see open issues".
Minor: the test count. 58 matches the t(...) calls in run_tests.py, but two contributors reported 59/59 on main (#62, #66), so some checks are counted at run time. A hard-coded number will keep drifting; consider "Expected: all PASSED" instead.
With the broken-tool marking in place, this is good to merge.
