The release-harness merge taught --resume to keep multi-token slash commands together, but that also misclassified absolute session paths as slash commands. This follow-up keeps the latest-session shortcut for real slash commands while still treating absolute and relative filesystem paths as explicit resume targets, which restores the new integration test and the intended resume flow.
Constraint: --resume must accept both implicit latest-session shortcuts and absolute filesystem paths
Rejected: Require --resume latest for all slash-command-only invocations | breaks the new shortcut UX merged from 9103/9202
Confidence: high
Scope-risk: narrow
Directive: Distinguish slash commands with looks_like_slash_command_token before assuming a leading slash means latest-session shorthand
Tested: cargo build -p rusty-claude-cli; cargo test -p rusty-claude-cli
Not-tested: Non-UTF8 session path handling
Add explicit top-level aliases for help/version/status/sandbox and return guidance for lone slash-command names so common command-style invocations do not fall through into prompt execution and unexpected auth/API work.
Constraint: Keep shorthand prompt mode working for natural-language multi-word input
Rejected: Remove bare prompt shorthand entirely | too disruptive to existing UX
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep single-word command guards aligned with the slash-command surface when adding new top-level UX affordances
Tested: cargo build -p rusty-claude-cli; cargo test -p rusty-claude-cli parses_single_word_command_aliases_without_falling_back_to_prompt_mode -- --nocapture; cargo test -p rusty-claude-cli single_word_slash_command_names_return_guidance_instead_of_hitting_prompt_mode -- --nocapture; cargo test -p rusty-claude-cli multi_word_prompt_still_uses_shorthand_prompt_mode -- --nocapture; cargo test -p rusty-claude-cli init_help_mentions_direct_subcommand -- --nocapture; cargo test -p rusty-claude-cli parses_login_and_logout_subcommands -- --nocapture; cargo test -p rusty-claude-cli parses_direct_agents_and_skills_slash_commands -- --nocapture; ./target/debug/claw help; ./target/debug/claw version; ./target/debug/claw status; ./target/debug/claw sandbox; ./target/debug/claw cost
Not-tested: cargo test -p rusty-claude-cli -- --nocapture still has a pre-existing failure in tests::init_template_mentions_detected_rust_workspace
Not-tested: cargo clippy -p rusty-claude-cli -- -D warnings still fails on pre-existing runtime crate lints
The release harness advertised resumed slash commands like /export <file> and /clear --confirm, but argv parsing split every slash-prefixed token into a new command. That made the claw binary reject legitimate resumed command sequences and quietly miss the caller-provided export target.
This change teaches --resume parsing to keep command arguments attached, including absolute export paths, and locks the behavior with both parser regressions and a binary-level smoke test that exercises the real claw resume path.
Constraint: Keep the scope to a high-confidence release-path fix that fits a ~1 hour hardening pass
Rejected: Broad REPL or network end-to-end coverage expansion | too slow and too wide for the release-confidence target
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: If new resume-supported commands accept slash-prefixed literals, extend the resume parser heuristics and add binary coverage for them
Tested: cargo test --workspace; cargo test -p rusty-claude-cli --test resume_slash_commands; cargo test -p rusty-claude-cli parses_resume_flag_with_absolute_export_path -- --exact
Not-tested: cargo clippy --workspace --all-targets -- -D warnings currently fails on pre-existing runtime/conversation/session lints outside this change
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
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
The Rust CLI now points users toward the right next step when they hit an
unknown slash command or mistype a flag, and it surfaces session shortcuts
more clearly in both help text and the REPL banner. It also lowers session
friction by accepting `latest` as a managed-session shortcut, allowing
`--resume` without an explicit path, and sorting saved sessions with
millisecond precision so the newest session is stable.
Constraint: Keep the change inside the existing Rust CLI surface and avoid overlapping new handlers
Constraint: Full workspace clippy -D warnings is currently blocked by pre-existing runtime warnings outside this change
Rejected: Add new slash commands for session shortcuts | higher overlap with already-landed handler work
Rejected: Treat unknown bare words as invalid subcommands | would break shorthand prompt mode
Confidence: high
Scope-risk: moderate
Directive: Preserve bare-word prompt mode when adjusting CLI parsing; only surface guidance for flag-like inputs and slash commands
Tested: cargo clippy -p rusty-claude-cli --bin claw --no-deps -- -D warnings
Tested: cargo test -p rusty-claude-cli
Tested: cargo run -q -p rusty-claude-cli -- --help
Tested: cargo run -q -p rusty-claude-cli -- --resum
Tested: cargo run -q -p rusty-claude-cli -- /stats
Not-tested: Full workspace clippy -D warnings still fails in unrelated runtime code
