HIP-0300 tools serialize results to JSON text, which flattened images into
useless base64-in-text. Add a ToolImage value type + one converter in
BaseTool.register: any ToolImage anywhere in a result becomes a real
mcp.types.ImageContent block; text-only results stay byte-for-byte JSON.
Emitters wired: fs read of image files, browser screenshots (bidi+playwright).
This gives hanzo-mcp vision parity with zai-mcp — an agent with native vision
(Claude) sees pixels directly, no per-task vision tool needed.
Also decomplect the core-package collision that caused this class of bug:
hanzo-tools-core shipped a DUPLICATE hanzo_tools/core/ that nondeterministically
shadowed canonical hanzo-tools (dropping ToolImage, the sophisticated register,
etc. — same shadow class as the 0.3.0 error-reexport gap). Finish the
'merge core into hanzo-tools' refactor: move id_tool into hanzo-tools, make
hanzo-tools-core a pure empty metapackage. Now ONE package owns hanzo_tools.core.
Versions: hanzo-tools 0.3.2, -core 0.3.1 (shim), -browser 0.5.9, -fs 0.3.4,
hanzo-mcp 0.15.12 (floors bumped). Verified: fs read PNG -> [text, image];
fs stat -> [text]; 29 tools intact; 9 tests pass.
Packaging metadata (twine check was PASSED-with-warnings -> clean PASS):
- config/llm/mcp/vector: add missing 'readme = README.md' ([project] key);
README files existed but were never wired into the dist metadata.
- net/plan/vcs: fill empty (0-byte) README.md files referenced by the
readme key, so long_description is no longer missing.
Tests (hanzo-tools-core/test_all_tools.py drifted from current sources):
- browser: 1 -> 3 tools (browser, cdp, playwright after the zapd split)
- mcp_tools: 4 -> 5 tools
- required-tool total: 21 -> 23
- Fix type shadowing in forgiving_edit.py (needle_lines int/list conflict)
- Add return type annotations to prompts functions
- Fix change_type indexing for None case in utils.py
- Fix commit.message bytes/str handling in utils.py
- Add proper dict typing for tree entries in utils.py
- Update shell tool count from 8 to 9 in test assertions
Run ruff check --fix and ruff format across the repo to fix ~495
auto-fixable lint errors (mostly I001 import sorting) and reformat
225 files to match the py312 target.

- Update uv.lock files in all sub-packages
- python-multipart 0.0.21 -> 0.0.22 (arbitrary file write fix)
- urllib3 2.6.1 -> 2.6.3 (decompression-bomb fix)
- Various other dependency updates
Note: docs/package-lock.json has next.js vulnerabilities that need
manual resolution due to npm dependency conflicts.
- hanzo-tools now contains core infrastructure (BaseTool, ToolRegistry, etc.)
- hanzo-tools-core becomes a thin backwards-compat wrapper
- All tool packages now depend on hanzo-tools>=0.3.0
- Reduces package count and simplifies dependency tree
Major improvements to mode and tool management:
1. Essential System Tools - Critical tools (llm, consensus, config, mode,
tool, version, stats) are now ALWAYS enabled regardless of active mode.
Previously, mode system disabled all tools then only enabled mode-specific
ones, causing critical tools to be unavailable.
2. Unified 'tool' Command - Consolidates tool_install, tool_enable,
tool_disable, tool_list into single 'tool' command with actions:
- list: List all tools by category
- enable/disable: Toggle tool state
- install/uninstall: Package management
- upgrade/reload: Update tools
- self_update: Update hanzo-mcp
3. Fixed Permission Manager - Made permission_manager optional in:
- FileSystemTool base class
- ComputerTool
- ConfigTool
- ReadTool, WriteTool, EditTool
Now creates default PermissionManager if not provided.
4. Fixed Mode System - Builtin modes (hanzo, minimal, fullstack, devops,
security) are now always registered alongside hanzo-persona profiles.
Previously they were skipped when hanzo-persona was available.
5. Updated ESSENTIAL_TOOLS constant with modern tool names and added
llm, consensus, config, mode to ensure they're in all default modes.
Version bump: 0.10.19 -> 0.10.20
- Add MCPResourceDocument.to_readable_string() for human-readable output
- Update search, find, lsp, refactor tools to use readable format
- Cleaner to_json_string() that doesn't double-wrap data
- Better formatted results with:
- Search stats and timing info
- Numbered results with file:line locations
- Truncated long matches for readability
- Pagination info
- Sync improvements to hanzo-tools-core package
