The default surface was 34 tools, 61 KB, ~15,300 tokens of schema in every
prompt of every agent. The mode system already names what a session should
carry, but only the tools register_all_tools enumerates obeyed it: zsh,
curl, playwright and the helpers (ps, npx, uvx, jq, wget, cdp, open) stayed
on in every mode. A mode now decides every discovered tool, the `hanzo`
mode lists what a coding agent calls every few steps (18 tools, 32 KB,
~8,000 tokens), and the rest is a name away: HANZO_MCP_ENABLED_TOOLS=a,b
or =all, `tool enable`, or `mode`.
hanzo-tools-shell 0.6.6: run_shell kept every byte a foreground command
wrote until the command ended. `yes` for thirty seconds is gigabytes. It
keeps the first 16 MiB per stream and drains the rest.
The tests' session-wide patch of asyncio.create_subprocess_exec handed
every shell command a stream that never reached EOF; the first test to run
one read it in a loop until the machine was out of memory (22 GB, killed).
The patch is now opt-in and its process has exited.
bench/latency.py measures the cold start, the tools/list bill and the common
calls through a real MCP client over stdio. Interleaved rounds, wall and CPU
seconds, p50 over 6 cold starts:

The installed environment's 9 s is its hanzoai 8.5.156, whose package init

hanzoai >= 8.5.624, which loads it lazily. Per-call latency is spawn-bound

machine's load; no call path changed.
Every mode disables a registered tool it does not list, and llm was
listed nowhere but HEAVY_TOOLS, written when it pulled a 100 MB client.
It is an HTTP call to api.hanzo.ai now, so llm and kai_decide join the
essential set every personality carries, and the llm package maps to the
two tools it ships.

hanzo-mcp said HELLO as consumer:hanzo-mcp/<pid> to a separate zapd
daemon, which the router that replaced it refuses as bad_id. Every
process that speaks ZAP now embeds the router (zapd 1.1 on PyPI) and the
kernel lock elects one; hanzo-mcp stands for it at startup and takes the
seat mcp/hanzo-<pid>. A browser is a browser/<host>/<name> node, found
by engine or name and reached with Node.call, and the extension's
command codec is unchanged.
hanzo-mcp pair prints the code the extension's popup takes. The daemon
spawn and socket probing are gone, and so is the zap-proto dependency.
hanzo_tools.core imports mcp.server.FastMCP, which mcp 2 removed, so a
fresh resolve that picks mcp 2.2.0 fails at import. The published
hanzo-mcp 0.15.17 already declares mcp<2; the tree now says the same,
and hanzo-tools, which owns the import, says it too.

An agent editing a web app needs the dev server's own view of it: which
routes exist, and whether the last edit broke the build. Next 16 serves
that over MCP at /_next/mcp, and Vite-based frameworks can with
vite-plugin-mcp, but nothing here found those endpoints.
index finds Next, Vite, Nuxt, Remix, React Router, Astro and SvelteKit
dev servers from each process's argv, cwd and listening ports, and lists
the tools of the MCP each serves. call runs one. errors returns current
build and runtime errors: Next's get_errors, after opening the app in the
browser tool, since Next reports only what a connected session reported;
otherwise Vite's error overlay, console errors and page errors, read
through the same browser tool.
discover() returns the servers as plain records, the shape a devserver
node will take. hanzo-mcp depends on the package so the tool ships.
Claude-Session: https://claude.ai/code/session_01Dc8DXc3fEQCRHUa6XWK4Ku
Nine per-service packages registered a hanzo.tools entry point and sat in
hanzo-mcp's default dependencies, so installing it put them in a model's tool
list beside the unified tool and without its filter.
hanzo-tools-kms offered inject, which lists a path and reads every secret at it.
hanzo-tools-iam offered create_user, delete_user and the token and session reads.
cloud withholds all of them from an agent; these were a second way to the same
API, so the rule held on one path and not the other.
The auto-registration is withdrawn, not the packages: they stay importable for a
human at a CLI, which is where reading a secret is a legitimate act. An agent
reaches all eight through the unified tool, verified against the live document.
mpc keeps its registration because the fleet has no equivalent, and auth keeps
its because it reads the caller's own claims rather than another identity's.
A version written into a manifest is written into every manifest that wants it,
which is how eslint came to exist in a hundred and four forms across this estate
and how a package came to resolve twice at run time. The catalog moves the number
out of the manifest: a manifest names the package, the workspace names the
version.
Four are held below their latest because the newer release cannot be used, and
the reason is recorded rather than the version alone: @noble/hashes 2 renamed
every subpath the web3 stack imports, @splinetool/runtime 2 depends on a package
that was never published, @dynamic-labs 5.4.1 the same, and react-resizable-panels
3 points its types condition at the bundle.
288 of hanzoai/ai's 294 operations now declare a response, against 1 before.
GET /v1/models, POST /v1/chat/completions, /v1/embeddings, /v1/messages —
every address a client actually calls — used to reach this client untyped,
because cloud's relay carried an operation's sentence and dropped the shapes
it named. It carries both now.
Fleet-wide the document goes from 69% to 81% of operations declaring what
comes back, which is where the ~208 new models here come from.
The quickstart called create_mcp_server, server.register_*_tools and
server.tools.read — no such names. The real surface is the hanzo-mcp
command, its flags, and HanzoMCPServer; the tools come from whichever
hanzo-tools-* packages are installed, through the hanzo.tools entry
point. Verified against --version, --help and the constructor.
Drop the three *_COMPLETE.md status reports, MODULAR_ARCHITECTURE.md
(a proposal), COMPREHENSIVE_DOCUMENTATION.md (claims 70+ tools over a
package with seven) and SEARCH_GUIDE.md (documents an ffind tool that
does not exist).
SECURITY_PATCH.md named files and lines for three findings in 0.8.13;
all three are addressed in 0.15.15 — the shell escaper it flagged is
gone with its module, permissions.py refuses .. and ~ before resolving,
and the third asked for a token the server minted, persisted to
~/.hanzo/mcp_token and never once checked. That token is gone too: auth
is IAM's, and a credential nothing verifies reads as a gate that is not
there.
hanzo_mcp.zap_server imported hanzo_tools.browser.zap_server, which does not
exist — the module could not be imported at all. Its caller swallowed that in
`except ImportError: return`, so _start_zap_server() ran on every `run()` and
started nothing, and the HANZO_NO_ZAP switch guarded a path that never had an
effect either way.
The browser tool reaches Chrome through the native host -> zapd -> the socket
at ~/.zap/run/zapd.sock, where hanzo-mcp is a consumer (hanzo_tools.browser
.zapd_consumer). That is the transport, so the WebSocket server and its mDNS
discovery go, along with _normalize_mcp_result, which existed to shape results
for that wire and had no other caller.
openai_api_check.py was not a test — pytest never collected it, nothing imported
it, and its whole body was a hand-run connectivity probe against a vendor with
the credential written in as a literal. There is nothing to keep.
The value it carried must still be rotated: it is in this repo's history and the
history is public.
This script carried its key as a literal. A key in a source file is a key in
every clone of that file, and this repo mirrors publicly, so the value must be
rotated independently of this change — removing it from the tip does not remove
it from history.
Reads OPENROUTER_API_KEY and exits with a clear message when it is unset.
0.15.13 shipped the 166-service surface switched off. `tools/list` against a
clean install returned 40 tools with no `hanzo`, and the server logged
"unified `hanzo` tool unavailable — keeping per-service tools enabled".
The import was fine; the mode gate was not. register_all_tools() asks
is_tool_enabled("hanzo", True), which returns tool_config["hanzo"] whenever the
key exists rather than falling back to the default. ModeLoader builds that
config by disabling every TOOL_REGISTRY key and re-enabling only the active
mode's tools. TOOL_REGISTRY has "hanzo"; the default personality's list did
not — so the "True" default was never reached and the tool was explicitly off.
Two things broke together, because the per-service cloud tools are retired only
once `hanzo` is enabled: the unified surface was absent AND the ten tools it
replaces were still mounted. The exact state 929e103e set out to end.
`hanzo` belongs in ESSENTIAL_TOOLS. It is an axis like fs or git — the single
seam to the platform — not a mode-specific extra. It stays out of
ESSENTIAL_SYSTEM_TOOLS so it remains disableable.
Verified in a clean uv venv from built wheels only (no editable, no PYTHONPATH):
tools/list now returns 31 tools including `hanzo`, and api/auth/billing/commerce/
iam/ingress/kms/mpc/paas/team are correctly gone (40 - 10 + 1). The tool answers
hanzo(service="services") with 166 services read live from
https://api.hanzo.ai/v1/openapi.json.
A test now pins the gate where it is actually decided. It fails against the
installed 0.15.13 (3 of 4) and passes against 0.15.14 — an import-level check
cannot catch this, because the import succeeds.

The unified `hanzo` tool imports HanzoCloud from hanzo_tools.core, which
hanzo-tools first shipped in 0.3.3 — but nothing in the dependency graph
required it. hanzo-tools-api asked for `hanzo-tools-core>=0.1.0`, an empty
shim whose own floor is hanzo-tools>=0.3.2, and 0.3.2 has no cloud.py at all.
A resolver was therefore free to satisfy every constraint and still produce an
install where `from hanzo_tools.core import HanzoCloud` raises ImportError.
That is exactly what happened: the legacy-tool gate logged "unified hanzo tool
not importable" and fell back, and the dev venv had to install hanzo-tools
editable to get a working `hanzo`.
Name the real dependency at the real floor:
- hanzo-tools-api: hanzo-tools-core>=0.1.0 -> hanzo-tools>=0.3.4. It imports
hanzo_tools.core directly, so it must depend on the package that owns it;
the >=0.1.0 shim floor also still admitted the shadowing duplicate.
- hanzo-tools-vector: hanzo-tools>=0.3.0 -> >=0.3.4 (cloud_vector.py).
- hanzo-mcp: hanzo-tools>=0.3.2 -> >=0.3.4, hanzo-tools-api>=0.3.1 -> >=0.3.2.
Metadata only, on versions not yet published. No version bumps.

The `hanzo` dispatcher hand-listed 10 services in SERVICE_TOOL_PATHS, so the
other ~150 cloud products were unreachable until someone cut a Python release.
Project the surface from cloud's /v1/openapi.json instead: cloud tags every
operation with its product (the first path segment after /v1/), so that document
already IS a service/action catalog. 166 services are now reachable, and a newly
mounted app is callable the moment cloud serves it.
Still exactly one MCP tool — agents degrade badly with hundreds — now shaped
hanzo(service, action, params, method), with `services` listing the catalog and
an empty action listing a service's actions.
Delete the local Infinity vector store (3,546 lines). It shipped no embedder, so
its only possible output was random vectors: it ranked "Bananas are yellow" above
an auth document for the query "authentication oauth jwt". A previous fix put the
mock behind HANZO_VECTOR_ALLOW_MOCK, but a fake that a flag can re-enable is
still a fake, and a tool that lies to an agent is worse than a missing one. The
package keeps only the cloud-backed VectorTool, and a test now fails if any
module in it imports `random`.
Make the legacy-tool gate honest: hide the per-service tools only once the
unified tool genuinely imports. It does not import against released hanzo-tools
(HanzoCloud is newer), and disabling them unconditionally would have left no
cloud tools at all.
- spec.py: catalog projection, cache keyed per spec source, stale cache beats
failing a call. HANZO_OPENAPI_URL decouples catalog from target so a partial
local host can be driven with the full registry.
- HanzoCloud.call: one generic seam for the verbs the spec names (PUT/PATCH/
DELETE); auth also resolves the hanzo CLI's IAM session, memoized.
- 40 new tests covering action naming, template binding, method inference,
param split, and cache fallback.

The first pass left three classes of config that BOTH tsc 5.9 and tsc 7
reject. Each was proven against both compilers before changing:
TS5090 A `paths` target must be relative once `baseUrl` is gone. The
first pass skipped the "./" prefix wherever baseUrl pointed at
the config's own directory, reasoning it was semantically
equivalent. It is not — without baseUrl a non-relative target
is rejected outright, by 5.9 as well as 7.
TS5110 `moduleResolution: node16` requires `module: node16`. The first
pass mapped commonjs projects to node16 resolution alone, which
BROKE those configs for the current toolchain. Both are now set.
TS5102 `downlevelIteration` is also removed in TS7; it was missing from
the dead-flag list.
Verified: repos that tsc 7 previously refused (base-studio, js-sdk, kv-js)
now report zero config errors on tsc 7 AND tsc 5.9.
Co-authored-by: Hanzo Dev <[email protected]>
TypeScript 7 is the native Go compiler and removes `baseUrl` and
`moduleResolution: node|node10`. Both appear here, so `tsc` from TS7
refuses the config outright (TS5102 / TS5108) and cannot typecheck.
`paths` targets resolve relative to `baseUrl` when it is set and relative
to the tsconfig file otherwise. Every `baseUrl` folded here already
pointed at the config's own directory, so dropping it moves nothing and
the targets are left byte-identical. Where a baseUrl pointed elsewhere,
each affected target was rewritten as join(baseUrl, target).
`moduleResolution` was chosen from the declared `module`: commonjs ->
node16, esnext/preserve -> bundler. Configs whose `module` is unset or
exotic were left alone rather than guessed at.
The result is accepted by BOTH toolchains, so nothing has to upgrade
TypeScript in lockstep. Verified on hanzo/chat packages/api: tsc 5.9
779 -> 778 errors (no regression), and tsc 7.0.2 now runs the project
in 2s where it previously refused the config.

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.
Regression guard for the hanzo-tools 0.3.0 core re-export gap that silently
dropped fs/exec/code/git/fetch/agent, leaving hanzo-mcp with only 13 tools.
Fails loudly if any entry point stops loading or the core error contract
(ToolError/ConflictError/InvalidParamsError/NotFoundError) regresses.
DynamicToolRegistry stored getattr(tool_class, 'description'), which for a
class-level @property returns the property DESCRIPTOR (not a str). 'tool list'
then did len(config.description) → 'object of type property has no len()',
breaking the entire tool-catalog command. Add _extract_tool_description
(mirrors _extract_tool_name): resolve a @property via a cheap instance, else
coerce to str, always returns str. Plus a defensive isinstance guard in the
list display path. Regression test covers property/unevaluable-property/plain/
absent + asserts every registered entry's description is len()-safe. 2 passed.
Closes the last gap in the one-way Hanzo control surface. IAM/KMS/PaaS
already had both CLI subcommands and MCP tools; S3 had neither.
- hanzo s3: buckets/mb/rb/ls/stat/rm/presign over hanzo_s3 (MinIO) client,
creds from env (inject from KMS, never plaintext). Registered in the
unified hanzo CLI alongside iam/kms/paas.
- hanzo-tools-s3: S3Tool MCP tool (same action-dispatch pattern as PaaSTool),
exported via the hanzo.tools entry point; s3 added to loader prefix map.
- uv workspace: map hanzo-cli/iam/kms/s3 + tools-s3 to local sources so the
unified CLI resolves on-disk packages (fixes hanzo_iam ImportError from a
stale published 1.29.0 wheel shadowing local 1.30.0).
Tests: 7 CLI + 14 MCP, all green.
Root cause of dead shell-exec: stale installs froze hanzo-tools-core 0.2.0 (no ToolError)
before 0.3.0 published, shadowing hanzo_tools.core and crashing the shell package import.
Floors now exclude it; a fresh/upgraded install always lands the consistent set.
* fix(browser-mcp): migrate CDP bridge -> zapd consumer; make disk authoritative
The MCP runtime kept pulling the buggy published wheel (hanzo-tools-browser
0.5.7) from PyPI instead of the migrated on-disk source, so every restart
re-broke the `cdp` tool. Reinstate `cdp` as a zapd-native tool, finish the
bridge->zapd migration (delete dead bridge/server modules + their tests), bump
to 0.5.8 and pin hanzo-mcp >=0.5.8, add the package to the uv workspace/sources
so disk is authoritative. 9/9 browser tests pass.
Pairs with the hanzoai/extension bridge->zapd migration (separate, still
uncommitted). The ~/.claude.json MCP invocation was also pointed at the local
editable source (machine config, not in this repo).
(cherry picked from commit 11b4d4ea8a5570d6fb0e51079fa445dba3713f71)
* fix(browser): drop dead lifecycle.py (in-process zap_server/cdp_bridge are gone)
lifecycle.py only wrapped the removed in-process ZAP server + CDP bridge; nothing
imports it under the zapd-consumer model. One way: transport is zapd_consumer,
tools are browser/cdp/playwright.

Published 0.2.0 predates 2cb7eb03: its ConfigTool passed
permission_manager positionally into BaseTool.__init__(self), so the
'config' tool failed registration on every server start (and 0.2.0
lacked WorkspaceTool entirely). The fix has sat unreleased on main —
same stranded-fix pattern as hanzoai.protocols. hanzo-mcp now floors
hanzo-tools-config>=0.2.1.
Floor hanzoai at 2.2.1 — the first release that actually ships
hanzoai.protocols, which permissions.py imports.
Drop the stderr→devnull redirect in stdio mode. The MCP stdio protocol
rides stdout alone; stderr is the channel clients log for diagnostics.
Silencing it turned the missing-module crash into a zero-byte mystery —
the client log literally suggests printing to stderr while the server
was throwing tracebacks into devnull. Run-loop failures also log with
exc_info so the traceback reaches the client log.
0.5.6 of hanzo-tools-browser shipped with a missing register() method
on CdpTool that crashed MCP startup. 0.5.7 fixes it. Floor bumped to
0.5.7 so pip/uv refuse to resolve the broken intermediate version.
Removes three console scripts that should never have been declared at the
top-level shell namespace from hanzo-mcp:
hanzo-dev — name-collided with the canonical Rust Codex-fork CLI
at /opt/homebrew/bin/hanzo-dev (~/work/hanzo/dev).
hanzo-plugin — unscoped; if needed, belongs in its own package.
hanzo-unified — vague + unscoped.
Modules remain importable (hanzo_mcp.dev_tools, .cli_plugin,
.unified_backend) so any user-facing entry point can ship from its own
package later. Only hanzo-mcp + hanzo-mcp-dev stay as scripts here.
Also bumps the hanzo-tools-browser floor to >=0.5.5 so the CdpTool alias
(mcp__hanzo__cdp) is guaranteed alongside mcp__hanzo__browser on every
hanzo-mcp install.
Two fixes for the canonical ZAP server:
1. Vendor the wire format (ZAP_MAGIC, MSG_*, MAX_MESSAGE_SIZE,
encode/decode) inside hanzo_tools/browser/zap_server.py instead of
importing from the external ``zap.protocol`` module — the published
``zap-protocol`` package on PyPI is now a ``zap-schema`` stub that
doesn't expose those symbols, so the import chain breaks for any
fresh install. Inlining ~40 lines keeps the spec self-contained and
matches the TS reference at extension/packages/browser/src/shared/zap.ts.
2. Pass ``host=self.host`` to ``zap_mdns.publish`` so the advertised
address matches the bound address. Default behaviour advertised the
outbound LAN IP via ``_local_ip()`` while the WebSocket was bound to
127.0.0.1; clients dialled the LAN IP and got ECONNREFUSED.
Drops the broken ``zap-protocol>=0.2.1`` dependency from both
hanzo-mcp and hanzo-tools-browser pyprojects — no longer needed.

Replaces the legacy per-operation tool list (read/write/edit/tree/dag/
zsh/shell/open) in PersonalityRegistry.ESSENTIAL_TOOLS with the six
HIP-0300 axes:
fs bytes + paths (read, write, edit, list, stat, apply_patch, search_text)
exec execution (run, background, ps, kill, logs)
code symbols (parse, search, transform, summarize)
git diffs + history
fetch network (get, post, download)
plan orchestration
Action-routed dispatch on top, not split tools — one tool per axis.
Keeps memory/think/critic/agent/config/mode/tool unchanged.
The MCP wire (what tools/list reports) ships exactly one tool per axis:
fs, exec, code, git, fetch, plan — action-routed. The per-action classes
(ReadTool, WriteTool, EditTool, …) stay importable for in-process
read-only sandboxing (swarm sub-agents) but are NOT on the wire.
PyPI 0.3.1 of hanzo-tools-fs shipped the legacy split (7 tools) while
the local 0.3.1 source had already migrated to TOOLS=[FsTool]. Same
version number, two different contracts — the source of the
'Python MCP surfaces 32 tools, Node MCP surfaces 13' divergence
that breaks contract parity. Bumping to 0.3.2 publishes the
HIP-0300 surface for the first time.
- pkg/hanzo-tools-fs 0.3.1 → 0.3.2: TOOLS=[FsTool]; legacy classes
importable; dropped 'Edit = EditTool' alias; cleaner __init__.
- pkg/hanzo-tools-shell 0.6.3 → 0.6.4: bump only (source already
TOOLS=_get_detected_shell_tools()).
- pkg/hanzo-tools-code 0.1.0 → 0.1.1: bump only (TOOLS=[CodeTool]).
- pkg/hanzo-tools-vcs 0.1.0 → 0.1.1: bump only (TOOLS=[GitTool]).
- pkg/hanzo-tools-net 0.1.0 → 0.1.1: bump only (TOOLS=[FetchTool]).
- pkg/hanzo-tools-plan 0.1.0 → 0.1.1: bump only (TOOLS=[PlanTool]).
- pkg/hanzo-tools-agent 0.3.1 → 0.3.2: 'Edit' alias is gone — call
EditTool by its real name in swarm_tool.py.
- pkg/hanzo-mcp 0.15.3 → 0.15.4: gets the HIP-0300-clean wire when
consumed via 'uvx --refresh-package hanzo-tools-fs hanzo-mcp serve'.
hanzo-mcp (0.15.1 -> 0.15.3):
- _normalize_mcp_result() collapses FastMCP list[TextContent] to parsed JSON
for ZAP MSG_RESPONSE serialization
- Closes the "TextContent not JSON serializable" bug surfaced when driving
the Hanzo extension from agent via tools/call
- Bump hanzo-tools-browser[playwright] floor to 0.5.4
hanzo-tools-browser (0.5.2 -> 0.5.4):
- mDNS-only ZAP discovery via _hanzo._tcp.local. (HIP-0069); no port pool,
no lockfile, OS-assigned ports advertised by hanzo-zap-mdns
- zap_server.py: refactor for unique server_id + retract on stop
- Test suite trimmed to the new wire contract
Patch-bump both packages.
- H-1: guard negative abs_off in obj_bytes() (buffer read bypass)
- H-2: remove CERT_NONE from ZapClient TLS (MITM protection)
- H-3: add MAX_MESSAGE_SIZE check in ZapServer (OOM DoS)
- M-5: log exceptions instead of bare pass in server
- L-1: validate ZAP version in Message.parse()
- L-2: wrap req_id at u32 boundary in CloudClient
Add hanzo-tools-ui to workspace members and hanzo-mcp dependencies so
the ui tool is actually discoverable at runtime. Add LocalUIClient that
reads components directly from ~/work/hanzo/ui when available, falling
back to GitHub API. Adds list_packages and read_file actions. Fixes
GitHub config components_path to match actual repo layout (pkg/ui/primitives).
- Rewrite zap_server.py to use asyncio TCP (not websockets library)
- ZAP server now speaks native binary protocol over raw TCP
- Wire format: [magic:4][type:1][length:4 BE][JSON payload]
- Remove websockets from ide optional dependency
- Fix type annotations: any -> Any, dict -> dict[str, Any]
- Add proper frame reading with asyncio.StreamReader.readexactly()
- Support MAX_MESSAGE_SIZE (16MB) limit per ZAP spec
- 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
