Add a foundational worker_boot control plane and tool surface for
reliable startup. The new registry tracks trust gates, ready-for-prompt
handshakes, prompt delivery attempts, and shell misdelivery recovery so
callers can coordinate worker boot above raw terminal transport.
Constraint: Current main has no tmux-backed worker control API to extend directly
Constraint: First slice must stay deterministic and fully testable in-process
Rejected: Wire the first implementation straight to tmux panes | would couple transport details to unfinished state semantics
Rejected: Ship parser helpers without control tools | would not enforce the ready-before-prompt contract end to end
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Treat WorkerObserve heuristics as a temporary transport adapter and replace them with typed runtime events before widening automation policy
Tested: cargo test -p runtime worker_boot
Tested: cargo test -p tools worker_tools
Tested: cargo check -p runtime -p tools
Not-tested: Real tmux/TTY trust prompts and live worker boot on an actual coding session
Not-tested: Full cargo clippy -p runtime -p tools --all-targets -- -D warnings (fails on pre-existing warnings outside this slice)
This resolves the stale-branch merge against origin/main, keeps the MCP runtime wiring, and preserves prompt-approved CLI tool execution after the mock parity harness additions landed upstream.
Constraint: Branch had to absorb origin/main changes through a contentful merge before more MCP work
Constraint: Prompt-approved runtime tool execution must continue working with new CLI/mock parity coverage
Rejected: Keep permission enforcer attached inside CliToolExecutor for conversation turns | caused prompt-approved bash parity flow to fail as a tool error
Rejected: Defer the merge and continue on stale history | would leave the lane red against current main
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Runtime permission policy and executor-side permission enforcement are separate layers; do not reapply executor enforcement to conversation turns without revalidating mock parity harness approval flows
Tested: cargo test -p rusty-claude-cli --test mock_parity_harness -- --nocapture; cargo test -p rusty-claude-cli -- --nocapture; cargo test --workspace -- --nocapture
Not-tested: Additional live remote/provider scenarios beyond the existing workspace suite
This wires configured MCP servers into the CLI/runtime path so discovered
MCP tools, resource wrappers, search visibility, shutdown handling, and
best-effort discovery all work together instead of living as isolated
runtime primitives.
Constraint: Keep non-MCP startup flows working without new required config
Constraint: Preserve partial availability when one configured MCP server fails discovery
Rejected: Fail runtime startup on any MCP discovery error | too brittle for mixed healthy/broken server configs
Rejected: Keep MCP support runtime-only without registry wiring | left discovery and invocation unreachable from the CLI tool lane
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Runtime MCP tools are registry-backed but executed through CliToolExecutor state; keep future tool-registry changes aligned with that split
Tested: cargo test -p runtime mcp -- --nocapture; cargo test -p tools -- --nocapture; cargo test -p rusty-claude-cli -- --nocapture; cargo test --workspace -- --nocapture
Not-tested: Live remote MCP transports (http/sse/ws/sdk) remain unsupported in the CLI execution path
The PermissionEnforcer was hard-denying tool calls that needed user
approval because it passes no prompter to authorize(). When the
active permission mode is Prompt, the enforcer now returns Allowed
and defers to the CLI's interactive approval flow.
Fixes: mock_parity_harness bash_permission_prompt_approved scenario
Add LspRegistry in crates/runtime/src/lsp_client.rs and wire it into
run_lsp() tool handler in crates/tools/src/lib.rs.
Runtime additions:
- LspRegistry: register/get servers by language, find server by file
extension, manage diagnostics, dispatch LSP actions
- LspAction enum (Diagnostics/Hover/Definition/References/Completion/Symbols/Format)
- LspServerStatus enum (Connected/Disconnected/Starting/Error)
- Diagnostic/Location/Hover/CompletionItem/Symbol types for structured responses
- Action dispatch validates server status and path requirements
Tool wiring:
- run_lsp() maps LspInput to LspRegistry.dispatch()
- Supports dynamic server lookup by file extension (rust/ts/js/py/go/java/c/cpp/rb/lua)
- Caches diagnostics across servers
8 new tests covering registration, lookup, diagnostics, and dispatch paths.
Bridges to existing LSP process manager for actual JSON-RPC execution.
Add McpToolRegistry in crates/runtime/src/mcp_tool_bridge.rs and wire
it into all 4 MCP tool handlers in crates/tools/src/lib.rs.
Runtime additions:
- McpToolRegistry: register/get/list servers, list/read resources,
call tools, set auth status, disconnect
- McpConnectionStatus enum (Disconnected/Connecting/Connected/AuthRequired/Error)
- Connection-state validation (reject ops on disconnected servers)
- Resource URI lookup, tool name validation before dispatch
Tool wiring:
- ListMcpResources: queries registry for server resources
- ReadMcpResource: looks up specific resource by URI
- McpAuth: returns server auth/connection status
- MCP (tool proxy): validates + dispatches tool calls through registry
8 new tests covering all lifecycle paths + error cases.
Bridges to existing McpServerManager for actual JSON-RPC execution.
Add TeamRegistry and CronRegistry in crates/runtime/src/team_cron_registry.rs
and wire them into the 5 team+cron tool handlers in crates/tools/src/lib.rs.
Runtime additions:
- TeamRegistry: create/get/list/delete(soft)/remove(hard), task_ids tracking,
TeamStatus (Created/Running/Completed/Deleted)
- CronRegistry: create/get/list(enabled_only)/delete/disable/record_run,
CronEntry with run_count and last_run_at tracking
Tool wiring:
- TeamCreate: creates team in registry, assigns team_id to tasks via TaskRegistry
- TeamDelete: soft-deletes team with status transition
- CronCreate: creates cron entry with real cron_id
- CronDelete: removes entry, returns deleted schedule info
- CronList: returns full entry list with run history
8 new tests (team + cron) — all passing.
Implements the runtime backbone for TaskCreate/TaskGet/TaskList/TaskStop/
TaskUpdate/TaskOutput tool surface parity. Thread-safe (Arc<Mutex>) registry
supporting:
- Create tasks with prompt/description
- Status transitions (Created → Running → Completed/Failed/Stopped)
- Message passing (update with user messages)
- Output accumulation (append_output for subprocess capture)
- Team assignment (for TeamCreate orchestration)
- List with optional status filter
- Remove/cleanup
7 new unit tests covering all CRUD + error paths.
Next: wire registry into tool dispatch to replace current stubs.
On GitHub Actions runners, `unshare` binary exists at /usr/bin/unshare
but user namespaces (CLONE_NEWUSER) are restricted, causing `unshare
--user --map-root-user` to silently fail. This produced empty stdout
in the bash_stdout_roundtrip parity test (mock_parity_harness.rs:533).
Replace the simple `command_exists("unshare")` check with
`unshare_user_namespace_works()` that actually probes whether
`unshare --user --map-root-user true` succeeds. Result is cached
via OnceLock so the probe runs at most once per process.
Fixes: CI red on main@85c5b0e (Rust CI run 23933274144)
Add a focused GitHub Actions workflow for pull requests into main plus
manual dispatch. The workflow checks workspace formatting and runs the
rusty-claude-cli crate tests so we get a real signal on the active Rust
surface without widening scope into a full matrix.
Because the workspace was not rustfmt-clean, include the formatting-only
updates needed for the new fmt gate to pass immediately.
Constraint: Keep scope to a fast, low-noise Rust PR gate
Constraint: CI should validate formatting and rusty-claude-cli without expanding to full workspace coverage
Rejected: Full workspace test or clippy matrix | too broad for the one-hour shipping window
Rejected: Add fmt CI without reformatting the workspace | the new gate would fail on arrival
Confidence: high
Scope-risk: narrow
Directive: Keep this workflow focused unless release requirements justify broader coverage
Tested: cargo fmt --all -- --check
Tested: cargo test -p rusty-claude-cli
Tested: YAML parse of .github/workflows/rust-ci.yml via python3 + PyYAML
Not-tested: End-to-end execution on GitHub-hosted runners
Claw already had the core slash-command and git primitives, but the UX
still made users work to discover them, understand current workspace
state, and trust what `/commit` was about to do. This change tightens
that flow in the same places Codex-style CLIs do: command discovery,
live status, typo recovery, and commit preflight/output.
The REPL banner and `/help` now surface a clearer starter path, unknown
slash commands suggest likely matches, `/status` includes actionable git
state, and `/commit` explains what it is staging and committing before
and after the model writes the Lore message. I also cleared the
workspace's existing clippy blockers so the verification lane can stay
fully green.
Constraint: Improve UX inside the existing Rust CLI surfaces without adding new dependencies
Rejected: Add more slash commands first | discoverability and feedback were the bigger friction points
Rejected: Split verification lint fixes into a second commit | user requested one solid commit
Confidence: high
Scope-risk: moderate
Directive: Keep slash discoverability, status reporting, and commit reporting aligned so `/help`, `/status`, and `/commit` tell the same workflow story
Tested: cargo fmt --all; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: Manual interactive REPL session against live Anthropic/xAI endpoints
Auto compaction was keying off cumulative usage and re-summarizing from the front of the session, which made long chats shed continuity after the first compaction. The runtime now compacts against the current turn's prompt pressure and preserves prior compacted context as retained summary state instead of treating it like disposable history.
Constraint: Existing /compact behavior and saved-session resume flow had to keep working without schema changes
Rejected: Keep using cumulative input tokens | caused repeat compaction after every subsequent turn once the threshold was crossed
Rejected: Re-summarize prior compacted system messages as ordinary history | degraded continuity and could drop earlier context
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Preserve compacted-summary boundaries when extending compaction again; do not fold prior compacted context back into raw-message removal
Tested: cargo fmt --check; cargo clippy -p runtime -p commands --tests -- -D warnings; cargo test -p runtime; cargo test -p commands
Not-tested: End-to-end interactive CLI auto-compaction against a live Anthropic session
The runtime now auto-compacts completed conversations once cumulative input usage
crosses a configurable threshold, preserving recent context while surfacing an
explicit user notice. The CLI also publishes the requested ant-only slash
commands through the shared commands crate and main dispatch, using meaningful
local implementations for commit/PR/issue/teleport/debug workflows.
Constraint: Reuse the existing Rust compaction pipeline instead of introducing a new summarization stack
Constraint: No new dependencies or broad command-framework rewrite
Rejected: Implement API-driven compaction inside ConversationRuntime now | too much new plumbing for this delivery
Rejected: Expose new commands as parse-only stubs | would not satisfy the requested command availability
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: If runtime later gains true API-backed compaction, preserve the TurnSummary auto-compaction metadata shape so CLI call sites stay stable
Tested: cargo test; cargo build --release; cargo fmt --all; git diff --check; LSP diagnostics directory check
Not-tested: Live Anthropic-backed specialist command flows; gh-authenticated PR/issue creation in a real repo
This threads typed hook settings through runtime config, adds a shell-based hook runner, and executes PreToolUse/PostToolUse around each tool call in the conversation loop. The CLI now rebuilds runtimes with settings-derived hook configuration so user-defined Claude hook commands actually run before and after tools.
Constraint: Hook behavior needed to match Claude-style settings.json hooks without broad plugin/MCP parity work in this change
Rejected: Delay hook loading to the tool executor layer | would miss denied tool calls and duplicate runtime policy plumbing
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep hook execution in the runtime loop so permission decisions and tool results remain wrapped by the same conversation semantics

This adds a small runtime sandbox policy/status layer, threads
sandbox options through the bash tool, and exposes `/sandbox`
status reporting in the CLI. Linux namespace/network isolation
is best-effort and intentionally reported as requested vs active
so the feature does not overclaim guarantees on unsupported
hosts or nested container environments.
Constraint: No new dependencies for isolation support
Constraint: Must keep filesystem restriction claims honest unless hard mount isolation succeeds
Rejected: External sandbox/container wrapper | too heavy for this workspace and request
Rejected: Inline bash-only changes without shared status model | weaker testability and poorer CLI visibility
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Treat this as observable best-effort isolation, not a hard security boundary, unless stronger mount enforcement is added later
Tested: cargo fmt --all; cargo clippy --workspace --all-targets --all-features -- -D warnings; cargo test --workspace
Not-tested: Manual `/sandbox` REPL run on a real nested-container host
Extended thinking needed to travel end-to-end through the API,
runtime, and CLI so the client can request a thinking budget,
preserve streamed reasoning blocks, and present them in a
collapsed text-first form. The implementation keeps thinking
strictly opt-in, adds a session-local toggle, and reuses the
existing flag/slash-command/reporting surfaces instead of
introducing a new UI layer.
Constraint: Existing non-thinking text/tool flows had to remain backward compatible by default
Constraint: Terminal UX needed a lightweight collapsed representation rather than an interactive TUI widget
Rejected: Heuristic CLI-only parsing of reasoning text | brittle against structured stream payloads
Rejected: Expanded raw thinking output by default | too noisy for normal assistant responses
Confidence: medium

This change makes compaction summaries durable under .claude/memory,
feeds those saved memory files back into prompt context, updates /memory

The Rust CLI now stores managed sessions under ~/.claude/sessions,
records additive session metadata in the canonical JSON transcript,
and exposes a /sessions listing alias alongside ID-or-path resume.
Inactive oversized sessions are compacted automatically so old
transcripts remain resumable without growing unchecked.
Constraint: Session JSON must stay backward-compatible with legacy files that lack metadata

The Rust CLI/runtime now models permissions as ordered access levels, derives tool requirements from the shared tool specs, and prompts REPL users before one-off danger-full-access escalations from workspace-write sessions. This also wires explicit --permission-mode parsing and makes /permissions operate on the live session state instead of an implicit env-derived default.
Constraint: Must preserve the existing three user-facing modes read-only, workspace-write, and danger-full-access

The runtime crate already had typed MCP config parsing, bootstrap metadata,

keeps unsupported transports explicit, and locks the behavior with
subprocess-backed discovery, routing, reuse, shutdown, and error tests.
Constraint: Keep the change narrow to the runtime crate and stdio transport only
