The root and Rust-facing docs now point readers at a single task-oriented usage guide with build, auth, CLI, session, and parity-harness examples. This also fixes stale workspace references and updates the Rust workspace inventory to match the current crate set.
Constraint: Existing README copy still referenced the old dev/rust status and needed to stay lightweight
Rejected: Fold all usage details into README.md only | too much noise for the landing page
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep USAGE examples aligned with when CLI flags change
Tested: cargo build --workspace; cargo test --workspace
Not-tested: External links and rendered Markdown in GitHub UI
The landed mock Anthropic harness now covers multi-tool turns, bash flows,
permission prompt approve/deny paths, and an external plugin tool path.
A machine-readable scenario manifest plus a diff/checklist runner keep the
new scenarios tied back to PARITY.md so future additions stay honest.
Constraint: Must build on the deterministic mock service and clean-environment CLI harness
Rejected: Add an MCP tool scenario now | current MCP tool surface is still stubbed, so plugin coverage is the real executable path
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep rust/mock_parity_scenarios.json, mock_parity_harness.rs, and PARITY.md refs in lockstep
Tested: cargo fmt --all
Tested: cargo clippy --workspace --all-targets -- -D warnings
Tested: cargo test --workspace
Tested: python3 rust/scripts/run_mock_parity_diff.py
Not-tested: Real MCP lifecycle handshakes; remote plugin marketplace install flows
This adds a deterministic mock Anthropic-compatible /v1/messages service,
a clean-environment CLI harness, and repo docs so the first parity
milestone can be validated without live network dependencies.
Constraint: First milestone must prove Rust claw can connect from a clean environment and cover streaming, tool assembly, and permission/tool flow
Constraint: No new third-party dependencies; reuse the existing Rust workspace stack
Rejected: Record/replay live Anthropic traffic | nondeterministic and unsuitable for repeatable CI coverage
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep scenario markers and expected tool payload shapes synchronized between the mock service and the harness tests
Tested: cargo fmt --all
Tested: cargo clippy --workspace --all-targets -- -D warnings
Tested: cargo test --workspace
Tested: ./scripts/run_mock_parity_harness.sh
Not-tested: Live Anthropic responses beyond the five scripted harness scenarios
Claw already exposes useful orchestration primitives such as session forking,
resume, ultraplan, agents, and skills, but compared with OmO/OMX
they were still high-friction to discover and re-type during live
operator loops.
This change makes the REPL act more like an orchestration console by
refreshing context-aware tab completions before each prompt, allowing
completion after slash-command arguments, and surfacing common workflow
paths such as model aliases, permission modes, and recent session IDs.
The startup banner and REPL help now advertise that guidance so the
capability is visible instead of hidden.
Constraint: Keep the improvement low-risk and REPL-local without adding dependencies or new command semantics
Rejected: Add a brand new orchestration slash command | higher UX surface area and more docs burden than a discoverability fix
Rejected: Implement a persistent HUD/status bar first | higher implementation risk than improving existing command ergonomics
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep dynamic completion candidates aligned with slash-command behavior and session management semantics
Tested: cargo test -p rusty-claude-cli
Not-tested: Interactive TTY tab-completion behavior in a live terminal session; full clippy remains blocked by pre-existing runtime crate lints
