feat(workspace): microkernel workspace decomposition — 16 crates, feature-gated subsystems by singlerider · Pull Request #5559 · zeroclaw-labs/zeroclaw

singlerider · 2026-04-09T16:04:38Z

Summary

Base branch target: master

Before: ZeroClaw is a single 289K LOC Rust crate. Every channel, tool, the gateway, the TUI wizard, hardware drivers, and the WASM plugin system are compiled into every binary whether used or not. Incremental compiles take 5+ minutes for any change. The minimum binary is 19MB. There is no way to build a lean kernel without the full agent runtime. The Microkernel Architecture RFC identified this as the core structural blocker for the v0.7.0→v1.0.0 roadmap.

After: ZeroClaw is a 16-crate workspace with clean dependency boundaries. The kernel (--no-default-features) is 6.6MB and can chat with an LLM with no runtime overhead. The agent runtime (zeroclaw-runtime), gateway (zeroclaw-gateway), TUI (zeroclaw-tui), WASM plugins (zeroclaw-plugins), and hardware (zeroclaw-hardware) are independently feature-gated crates. Channel features forward directly from root to zeroclaw-channels in one hop. Subsystems communicate across crate boundaries through callback injection — no circular dependencies. All public API paths are preserved via re-export stubs. No behavioral changes with default features. Config format and CLI interface unchanged. Version remains 0.6.9 — version bump is a code owner decision, separate from this refactor.

What did not change: Default cargo build produces the same binary with the same behavior. All 6,912 tests pass. No config migration required. No CLI changes.

Dependency Graph (simplified)

                   /    |    |    \    \

           api       api    api

Key: runtime does NOT depend on channels, gateway, tui, hardware, or plugins. Binary wires them together via callbacks (DaemonSubsystems).

Known Follow-ups

fix(channels): move Telegram and Matrix channel implementations out of orchestrator #5599 — Move Telegram/Matrix/CLI implementations out of orchestrator into proper channel files
Cron delivery wiring — deliver_announcement stubbed, needs callback from orchestrator
Onboard wizard nostr/whatsapp-web/hardware code disabled — needs callback wiring
Peripheral tools injection — stubbed in agent loop, binary needs to wire at startup

Human Test Plan (required before merge)

These tests exercise the callback wiring points that compile and pass unit tests but have not been verified end-to-end with real services.

Build commands

Test	Build command
Daemon startup	`cargo build --release` (default features include everything)
TUI wizard	`cargo build --release` (tui-onboarding is in default)
Kernel-only	`cargo build --release --no-default-features`
Cron delivery	`cargo build --release`
Hardware tools	`cargo build --release --features hardware`
Gateway webhooks	`cargo build --release`
Selective channel	`cargo build --release --no-default-features --features agent-runtime,channel-discord`
Channel message flow	`cargo build --release`

All release builds use target/release/zeroclaw. Debug builds (cargo build without --release) work too but are slower at runtime.

Smoke tests (do these first)

Daemon startup — cargo build --release && ./target/release/zeroclaw daemon. Gateway binds, channels connect. Exercises all three DaemonSubsystems callbacks (gateway_start, channels_start, mqtt_start).
TUI wizard — cargo build --release && ./target/release/zeroclaw onboard --tui. Launches the ratatui wizard. Now in zeroclaw-tui crate. Nostr/whatsapp-web/hardware sections are disabled (fix(onboard): wire nostr, whatsapp-web, and hardware wizard sections after crate extraction #5603) — confirm everything else works.
Kernel-only build — cargo build --release --no-default-features && ./target/release/zeroclaw with a provider configured. Interactive CLI chat works. Verifies the kernel is self-sufficient without the runtime.

Callback wiring tests

Cron delivery — cargo build --release && ./target/release/zeroclaw daemon. Create a cron job with delivery.mode = "announce" targeting a configured channel. Run it. Announcement arrives. Exercises register_delivery_fn callback through the orchestrator.
Hardware tools — cargo build --release --features hardware && ./target/release/zeroclaw hardware discover. With hardware connected, device list appears. Then ./target/release/zeroclaw daemon — peripheral tools register in agent. Exercises register_peripheral_tools_fn callback.

Integration tests

Gateway webhooks — cargo build --release && ./target/release/zeroclaw daemon. Send a test webhook to a channel endpoint (Telegram, Discord, WhatsApp). Gateway routes it correctly. Gateway is a new crate; all internal refs were rewritten.
Selective channel build — cargo build --release --no-default-features --features agent-runtime,channel-discord. Only Discord compiles. Orchestrator handles missing channels without panic. Run daemon with Discord configured.
Channel message flow — cargo build --release && ./target/release/zeroclaw daemon. Send a message through a real channel (Telegram, Discord, etc). Agent responds. Full round-trip through orchestrator → agent loop → tool execution → response.

How to resolve

Recommended approach: Merge upstream/master into your feature branch and resolve conflicts:

git fetch upstream master
git checkout your-feature-branch
git merge upstream/master
# Resolve conflicts using the table above
git add -A
git merge --continue

For each conflicted file:

Accept the 1-line re-export stub for src/X/mod.rs
Apply your real code changes to the corresponding file in crates/ (see table above)
New files that did not exist before your branch should be created directly in crates/
If your branch uses use crate::runtime:: — change to use crate::platform::
If your branch adds a channel feature to root Cargo.toml — channel features now forward directly to crates/zeroclaw-channels/Cargo.toml
Do NOT put implementation code in src/X/mod.rs — those are re-export stubs only

Resolving `src/` stub conflicts

For each conflicted src/X/mod.rs or src/X/*.rs:

# Accept the upstream stub version for ALL src/ files
git checkout --theirs src/channels/*.rs src/config/schema.rs src/daemon/mod.rs \
  src/doctor/mod.rs src/gateway/mod.rs src/providers/mod.rs src/tools/*.rs
git add src/

These are now 1-line re-export stubs. Your real code changes go in crates/ (see table above).

Resolving `crates/` conflicts

For conflicted files in crates/:

Keep your semantic changes (the feature you are building)
Use upstream import paths (zeroclaw_config::schema::Config not crate::config::Config)
If your branch renamed fields on Config, apply those renames in crates/zeroclaw-config/src/schema.rs

Moving new files

If your branch created new files in src/config/, src/channels/, etc.:

# Move to the correct crate
mv src/config/my_new_file.rs crates/zeroclaw-config/src/my_new_file.rs

# Add module declaration in the crate's lib.rs
echo "pub mod my_new_file;" >> crates/zeroclaw-config/src/lib.rs

# Add re-export in src/config/mod.rs (so root crate can still use it)
echo "pub use zeroclaw_config::my_new_file;" >> src/config/mod.rs

Import path fixes

Code in workspace crates cannot use crate::config::* — that only works in the root crate. Fix these:

Old path (in crate code)	New path
`crate::config::Config`	`zeroclaw_config::schema::Config`
`crate::config::schema::*`	`zeroclaw_config::schema::*`
`crate::config::migration::*`	`zeroclaw_config::migration::*`
`crate::providers::*`	`zeroclaw_providers::*`
`memory::*`	`zeroclaw_memory::*`
`crate::channels::*`	(use re-exports from `zeroclaw_channels::orchestrator::*`)

Adding dependencies to workspace crates

If your branch added a dependency to root Cargo.toml that is now needed by a workspace crate:

# In crates/zeroclaw-config/Cargo.toml (not root)
toml_edit = "0.25"

`JsonSchema` derive in workspace crates

The schemars crate is behind feature = "schema-export" in workspace crates. Do NOT use bare derive(JsonSchema):

// Wrong:
#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]

// Correct:
#[derive(Debug, Clone, Serialize, Deserialize)]
#[cfg_attr(feature = "schema-export", derive(schemars::JsonSchema))]

After resolving, check for stale paths

# Old module name
grep -rn "crate::runtime\b" src/ crates/zeroclaw-runtime/src/
# Should be crate::platform (the module was renamed)

# Old import paths in crates
grep -rn "crate::config::" crates/ --include="*.rs" | grep -v target | grep -v "//\|shim\|macro"
# Should be zeroclaw_config:: (crates cannot use crate::config)

# Old field names (if your PR renamed them)
grep -rn "\.channels_config\b" crates/ --include="*.rs" | grep -v target
# Should be .channels if V2 schema is active

Validation gate

Run all three feature combos before pushing:

cargo fmt --all -- --check
cargo clippy --all-targets -- -D warnings
cargo clippy --bin zeroclaw --no-default-features -- -D warnings
cargo clippy --workspace --exclude zeroclaw-desktop --all-targets --features ci-all -- -D warnings
cargo test --workspace --features ci-all

Closes #5635
Closes #4656

…fig crates Extract three workspace crates from the monolithic root crate to reduce incremental compile times and establish the dependency foundation for further workspace splitting (zeroclaw-labs#5272). zeroclaw-types: Core trait definitions (Provider, Channel, Tool) and shared data types (ChatMessage, ToolSpec, MediaAttachment, TurnEvent, etc.). Includes blanket `impl Provider for Arc<T>` replacing 6 manual delegation impls. zeroclaw-infra: Channel infrastructure (debounce, stall watchdog, session backends) with minimal dependencies. zeroclaw-config: The 16K LOC config schema, secrets store, domain matcher, autonomy level, provider alias functions, and scattered config types previously defined in agent/channels/tools/trust modules. Includes shim modules for Configurable derive macro compatibility. All existing `crate::` import paths preserved via re-export stubs. Zero test file changes. All tests pass.

Move all LLM provider implementations (30K LOC), auth services, and multimodal processing into a standalone workspace crate. Includes: anthropic, openai, gemini, ollama, bedrock, copilot, claude_code, compatible (generic OpenAI-compatible), reliable (retry/fallback), router (model routing), telnyx, openrouter, azure_openai, gemini_cli, kilocli, openai_codex, plus auth/ and multimodal.rs. Also moves SchemaCleanr (tool schema cleaning, 842 LOC) and TOOL_CHOICE_OVERRIDE task-local to zeroclaw-types since providers need them and they have no agent dependencies. 755 tests pass in the providers crate. 20 trait tests pass in root. All pub(crate) items promoted to pub for cross-crate access.

Move ~1,500 lines of tool call parsing logic and ~1,700 lines of parsing tests from src/agent/loop_.rs into a standalone crate. The parser handles a dozen LLM output formats: JSON, XML <tool_call> tags, GLM-style shortened syntax, MiniMax <invoke> blocks, Perl-style [TOOL_CALL] blocks, markdown fences, OpenAI native format, and more. This is the RFC's D2 deliverable — the most fuzz-testable code in the project, now independently compilable and testable. loop_.rs: 9,590 → 6,123 lines (-36%) Parser crate: 91 tests pass Root crate: all tests pass

Rename the types crate to zeroclaw-api to align with the Microkernel Architecture RFC. Add Memory, Observer, RuntimeAdapter, and Peripheral traits to complete the API layer — all seven core traits now live in zeroclaw-api with zero implementation dependencies. This is the RFC's D1 deliverable: a single crate that defines all ZeroClaw interfaces. The compiler enforces that no implementation crate can import another without going through these abstractions. Traits in zeroclaw-api: Provider, Channel, Tool, Memory, Observer, RuntimeAdapter, Peripheral.

Move memory backends, embeddings, consolidation, retrieval, and factory functions (12K LOC) into a standalone workspace crate. Depends only on zeroclaw-api and zeroclaw-config. Root keeps: mod.rs (re-export stub), cli.rs (depends on root commands), battle_tests.rs (integration tests), traits.rs (re-export with tests).

zeroclaw-memory: 12K LOC — backends (SQLite, Markdown, Qdrant, None), embeddings, consolidation, retrieval, vector search, knowledge graph, response cache, policy enforcer, factory functions. Root keeps cli.rs and battle_tests.rs. zeroclaw-channels: 32 channel implementations (~38K LOC) — Discord, Slack, Telegram (stays in root), IRC, email, Gmail, Bluesky, Twitter, Reddit, Notion, Lark, Matrix (stays in root), WhatsApp, Signal, Mattermost, DingTalk, QQ, WeChat, and more. Includes feature-gated optional channels (email, lark, nostr, whatsapp-web, voice-wake). Root keeps mod.rs (12K orchestrator), cli.rs, and channels with root-only deps (telegram, matrix, mqtt, acp_server).

Move 69 tool implementations (~43K LOC) into a standalone workspace crate. Includes: browser, file ops, git, memory, web search/fetch, HTTP, image gen, canvas, cloud ops, Jira, Notion, Google Workspace, MS365, LinkedIn, Composio, MCP client/transport/protocol, calculator, data management, sessions, screenshots, and more. Also moves SecurityPolicy (3.4K LOC) from src/security/policy.rs to zeroclaw-config, enabling tools to depend on it without a circular dependency on the root crate. Root keeps: mod.rs (tool registration), 21 tools with root-only deps (cron_*, sop_*, delegate, shell, skill_*, schedule, model_switch, file_read, node_tool, verifiable_intent, security_ops).

…ty policy Replace 32 channel source files and 69 tool source files in root with one-line re-export stubs pointing to their workspace crates. Replace SecurityPolicy (3.4K LOC) in root with re-export from zeroclaw-config. Root crate now compiles using code from the extracted workspace crates instead of its own copies. All 2,504 root tests pass, plus 755 provider crate tests and 91 parser crate tests. Channel features (channel-email, channel-lark) forwarded to zeroclaw-channels in root Cargo.toml.

Delete 56 source files from root that are no longer compiled — their modules were removed from mod.rs when re-export stubs were wired up. The code lives in zeroclaw-providers, zeroclaw-memory, and zeroclaw-auth. Root crate: 259K → 142K LOC.

…config Move gateway-blocking types out of root into zeroclaw-config: - PairingGuard (753 LOC) — device pairing and auth - CostTracker (566 LOC) — token usage and budget tracking - Runtime module (464 LOC) — NativeRuntime, DockerRuntime, factory All are zero-dep on root crate internals. Root re-export stubs preserve existing import paths. 2,444 tests pass. Gateway extraction deferred — api.rs and lib.rs have deep ties to cron, health, hooks, doctor, and observability that need extraction first (or the RFC's IPC API approach in Phase 3/v0.9.0).

Move everything except agent loop, gateway, channels orchestrator, and main.rs into zeroclaw-misc. Includes: - Security (10K): policy, audit, sandboxing, pairing, webauthn, OTP - Observability (3.4K): Prometheus, OpenTelemetry backends - SOP engine (6.5K): standard operating procedures - Cron (5K): scheduler, job store, types - Skills (5K): creation, audit, discovery - Hardware (7.6K): device detection, board support - TUI (4.2K): onboarding wizard, theme - Tunnel (1.7K): Cloudflare, ngrok, Tailscale - And: approval, commands, cost, health, heartbeat, hooks, identity, integrations, migration, nodes, onboard, peripherals, plugins, rag, routines, runtime, service, skillforge, trust, verifiable_intent Root crate: 289K → 127K LOC. 1,635 tests pass. Total extracted: 245K LOC across 10 workspace crates.

…oclaw-misc Extract EVERYTHING except main.rs, lib.rs, and CLI dispatch stubs into workspace crates. Agent loop, gateway, channels orchestrator, daemon, doctor, cron scheduler — all now in zeroclaw-misc. Root crate: 289K → 27K LOC (90% reduction) Extracted: 283K LOC across 10 workspace crates Tests: 539 root + 755 providers + 91 parser = 1,385 total, 0 failures Root now contains only: - main.rs (3K) — CLI entrypoint - lib.rs — module declarations - Re-export stubs for all extracted modules - CLI handle_command functions (thin wrappers calling into misc) - tools/mod.rs (1.4K) — tool registration - commands/ (882) — self_test and update

Remove 23 duplicated tool files from root (12K LOC), replace microsoft365 files in misc with re-export stubs, fix skill_http/ skill_tool cross-references. Total project LOC: 293,721 (was 291,380 — 2,341 lines of workspace scaffolding overhead, zero code duplication). Root crate: 12,850 LOC (was 289K).

Strip root service/integrations/migration stubs to re-export + handle_command only. Restore full implementations in zeroclaw-misc. Make private functions pub where needed for cross-crate access. Total project: 292,806 LOC (original 291,380 — 1,426 lines structural overhead). Zero code duplication. 230 root tests pass.

Delete 110 re-export shim files from zeroclaw-misc. Rewrite channel and tool orchestrators to import directly from source crates (zeroclaw-channels, zeroclaw-tools, zeroclaw-api, zeroclaw-infra) instead of through local shim modules. This eliminates the need for dual feature forwarding — each feature only forwards to the crate that owns the code. The misc orchestrator uses direct crate paths (zeroclaw_channels::discord::DiscordChannel) so features only need to be declared in the source crate. Total: 292,582 LOC (1,202 structural overhead vs 291,380 original). Zero code duplication. 230 root tests pass.

Gateway (axum, hyper, tower, rust-embed) and TUI (ratatui, crossterm) are now behind optional features in zeroclaw-misc. Root forwards gateway and tui-onboarding features. cargo check --no-default-features compiles without gateway or TUI deps. Both are in default features so existing behavior is preserved. 230 tests pass.

Declare 28 channel features in zeroclaw-channels, forward through zeroclaw-misc to root. Each channel can be independently toggled. Gateway and TUI already optional from previous commit. Feature forwarding chain: root → misc → channels. Each crate declares the feature for its own cfg gates. No shim files, no code duplication in the forwarding — just one-line Cargo.toml declarations. All 28 channels + email + lark + telegram + nostr are in default. ci-all includes all features. Default: 230 tests pass. Note: --no-default-features doesn't fully compile yet — the channels orchestrator and gateway need per-function cfg gates around channel- specific code paths. That's surgical refactoring for a follow-up.

Add cfg gates for gateway, TUI, email channel, node_tool, skill creator, and daemon gateway spawn. Main.rs uses wrapper functions with cfg-gated implementations that bail with a message when the feature is disabled. cargo check --no-default-features: clean cargo check (default): clean cargo test --lib: 230 pass

Convert 165+ #[derive(JsonSchema)] to #[cfg_attr(feature = "schema-export", derive(schemars::JsonSchema))]. Update Configurable proc macro to emit cfg-gated enum_variants calls. Make schemars optional in zeroclaw-config and zeroclaw-misc. Feature chain: root → misc → config, each forwarding schema-export. In default features so existing behavior preserved. Without it, ~2MB savings from not compiling schemars. cargo check --no-default-features: clean (no schemars compiled) cargo check (default): clean cargo test: 230 pass

Replace aws-lc-rs (5MB C library, slow to compile) with ring as the TLS crypto provider. Set default-features = false on rustls and tokio-rustls across all workspace crates to prevent aws-lc-rs from being pulled in through feature unification. aws-lc-sys is no longer in the dependency tree. Build times improve (no C compilation for TLS). Binary size with .eh_frame stripping: 19MB → 17MB. The 3MB kernel target requires making workspace crates themselves optional deps of root (so --no-default-features doesn't compile channels/tools/misc at all). That's a deeper refactor of main.rs.

Make zeroclaw-misc, zeroclaw-channels, and zeroclaw-tools optional deps of root, activated by the "agent-runtime" feature. All existing features (gateway, channels, tools, etc.) imply agent-runtime. --no-default-features builds a kernel-only binary: CLI agent with provider chat, config loading, and nothing else. No channels, no gateway, no tools, no TUI, no SOP, no cron. Binary size: Full (default): 19MB (17MB stripped) Kernel (no-default): 7.3MB (6.6MB stripped) The kernel binary supports: zeroclaw agent "message" and interactive stdin chat. All other commands bail with "requires agent-runtime". 230 tests pass with default features.

Fix missing deps for voice-wake (cpal), whatsapp-web (wa-rs-*, qrcode), channel-nostr (nostr-sdk in misc), channel-matrix (matrix-sdk in misc), hardware (nusb, tokio-serial in misc). Fix broken firmware include_bytes! paths with symlink. Fix VoiceWakeConfig missing Configurable derive. Fix voice_wake sample_rate type.
