The custom crossterm editor now supports prompt history, slash-command tab
completion, multiline editing, and Ctrl-C semantics that clear partial input
without always terminating the session. The live REPL loop now distinguishes
buffer cancellation from clean exit, persists session state on meaningful
boundaries, and renders tool activity in a more structured way for terminal
use.
Constraint: Keep the active REPL on the existing crossterm path without adding a line-editor dependency
Rejected: Swap to rustyline or reedline | broader integration risk than this polish pass justifies
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep editor state logic generic in input.rs and leave REPL policy decisions in main.rs
Tested: cargo fmt --manifest-path rust/Cargo.toml --all; cargo clippy --manifest-path rust/Cargo.toml --all-targets --all-features -- -D warnings; cargo test --manifest-path rust/Cargo.toml
Not-tested: Interactive manual terminal smoke test for arrow keys/tab/Ctrl-C in a live TTY
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
Constraint: Must avoid new dependencies and keep enforcement inside the existing runtime/tool plumbing
Rejected: Keep the old Allow/Deny/Prompt policy model | could not represent ordered tool requirements across the CLI surface
Rejected: Continue sourcing live session mode solely from RUSTY_CLAUDE_PERMISSION_MODE | /permissions would not reliably reflect the current session state
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Add required_permission entries for new tools before exposing them to the runtime
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test -q
Not-tested: Manual interactive REPL approval flow in a live Anthropic session
The remaining slash commands already existed in the REPL path, so this change
focuses on wiring the active CLI parser and runtime to expose them safely.
`--version` now exits through a local reporting path, and `--allowedTools`
constrains both advertised and executable tools without changing the underlying
command surface.
Constraint: The active CLI parser lives in main.rs, so a full parser unification would be broader than requested
Constraint: --version must not require API credentials or construct the API client
Rejected: Migrate the binary to the clap parser in args.rs | too large for a parity patch
Rejected: Enforce allowed tools only at request construction time | execution-time mismatch risk
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep local-only flags like --version on pre-runtime codepaths and mirror tool allowlists in both definition and execution paths
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test; cargo run -q -p rusty-claude-cli -- --version; cargo run -q -p rusty-claude-cli -- --help
Not-tested: Interactive live API conversation with restricted tool allowlists
This adds an end-to-end OAuth PKCE login/logout path to the Rust CLI,
persists OAuth credentials under the Claude config home, and teaches the
API client to use persisted bearer credentials with refresh support when
env-based API credentials are absent.
Constraint: Reuse existing runtime OAuth primitives and keep browser/callback orchestration in the CLI
Constraint: Preserve auth precedence as API key, then auth-token env, then persisted OAuth credentials
Rejected: Put browser launch and token exchange entirely in runtime | caused boundary creep across shared crates
Rejected: Duplicate credential parsing in CLI and api | increased drift and refresh inconsistency
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep logout non-destructive to unrelated credentials.json fields and do not silently fall back to stale expired tokens
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test
Not-tested: Manual live Anthropic OAuth browser flow against real authorize/token endpoints
This adds the remaining user-facing slash commands, enables non-interactive model and JSON prompt output, and tightens the help and startup copy so the Rust CLI feels coherent as a standalone interface.
The implementation keeps the scope narrow by reusing the existing session JSON format and local runtime machinery instead of introducing new storage layers or dependencies.
Constraint: No new dependencies allowed for this polish pass
Constraint: Do not commit OMX runtime state
Rejected: Add a separate session database | unnecessary complexity for local CLI persistence
Rejected: Rework argument parsing with clap | too broad for the current delivery window
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Managed sessions currently live under .claude/sessions; keep compatibility in mind before changing that path or file shape
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test
Not-tested: Live Anthropic prompt execution and interactive manual UX smoke test
Tighten the /permissions report into the same operator-console style used by
other slash commands, and make permission mode changes read like a structured
CLI confirmation instead of a raw field swap.
Constraint: Must keep the real permission surface limited to read-only, workspace-write, and danger-full-access
Rejected: Add synthetic shortcuts or approval-state variants | would misrepresent actual supported modes
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep /permissions output aligned with other structured slash command reports as new mode metadata is added
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace; manual REPL smoke test for /permissions and /permissions read-only
Not-tested: Interactive approval prompting flows beyond mode report formatting
Reformat /compact output for both live and resumed sessions so compaction results are reported in the same structured console style as the rest of the CLI surface. This keeps the behavior unchanged while making skipped and successful compaction runs easier to read.
Constraint: Compact output must stay faithful to the real compaction result and not imply summarization details beyond removed/kept message counts
Rejected: Expose the generated summary body directly in /compact output | too noisy for a lightweight command-response surface
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep lifecycle and maintenance command output stylistically consistent as more slash commands reach parity
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual terminal UX review of compact output on very large sessions
Reformat /init results into the same structured operator-console style used by the other polished commands so create and skip outcomes are easier to scan. This keeps the command behavior unchanged while making repo bootstrapping feedback feel more intentional.
Constraint: /init must stay non-destructive and continue refusing to overwrite an existing CLAUDE.md
Rejected: Expand /init to write more files in the same slice | broader scaffolding would be riskier than a focused UX polish commit
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep /init output explicit about whether the file was created or skipped so users can trust the command in existing repos
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual /init run in a repo that already has a heavily customized CLAUDE.md
Extend /config so operators can inspect specific merged sections like env, hooks, and model while keeping the command read-only and grounded in the actual loaded config. This improves Claude Code-style inspectability without inventing an unsafe config editing surface.
Constraint: Config handling must remain read-only and reflect only the merged runtime config that already exists
Rejected: Add /config set mutation commands | persistence semantics and edit safety are not mature enough for a small honest slice
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep config subviews aligned with real merged keys and avoid advertising writable behavior until persistence is designed
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual inspection of richer hooks/env config payloads in a customized user setup
Reformat /memory into the same structured console style as the other polished commands and enumerate discovered instruction files in ancestry order with line counts and previews. This makes repo instruction memory easier to inspect without changing the underlying discovery behavior.
Constraint: Memory reporting must reflect only the instruction files discovered from current directory ancestry
Rejected: Add memory editing commands in the same slice | presentation polish was a cleaner, lower-risk improvement to ship first
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep instruction-file ordering stable so ancestry-based memory debugging stays predictable
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual inspection of repos with many nested CLAUDE files
Extend /status with project root and git branch details derived from the local repository so the report feels closer to a real Claude Code session dashboard. This adds high-value workspace context without inventing any persisted metadata the runtime does not actually have.
Constraint: Status metadata must be computed from the current working tree at runtime and tolerate non-git directories
Rejected: Persist branch/root into session files first | a local runtime derivation is smaller and immediately useful without changing session format
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep status context opportunistic and degrade cleanly to unknown when git metadata is unavailable
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual non-git-directory /status run
Update in-REPL /resume success output to the same structured console style used elsewhere so session lifecycle commands feel consistent with status, model, permissions, config, and cost. This preserves the same behavior while improving operator readability.
Constraint: Resume output must stay grounded in real restored session metadata already available after load
Rejected: Add more restored-session details like cwd snapshot | that data is not yet persisted in session files
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep lifecycle command outputs stylistically aligned as the CLI surface grows
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual interactive comparison of /resume output before and after multiple restores
Refresh shared slash help and REPL help wording so the command surface reads more like an integrated console, and make successful /clear output match the newer structured reporting style. This keeps discoverability consistent now that status, model, permissions, config, and cost all use richer operator-oriented copy.
Constraint: Help text must stay synchronized with the actual implemented command surface and resume behavior
Rejected: Larger README/doc pass in the same commit | keeping the slice limited to runtime help/output makes it easier to review and revert
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Prefer shared help-copy changes in commands crate first, then layer REPL-specific additions in the CLI binary
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual comparison of help wording against upstream Claude Code terminal screenshots
Reformat /cost for both live and resumed sessions so token accounting is presented in the same sectioned operator-console style as status, model, permissions, and config. This improves consistency across the command surface while preserving the same underlying usage metrics.
Constraint: Cost output must continue to reflect cumulative tracked usage only, without claiming real billing or currency totals
Rejected: Add dollar estimates | there is no authoritative pricing source wired into this CLI surface
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep /cost focused on raw token accounting until pricing metadata exists in the runtime layer
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual terminal UX review for very large cumulative token counts
Rework /permissions output into the same operator-console format used by status, config, and model so the command feels intentional and self-explanatory. Switching modes now reports previous and current state, while inspection shows the available modes and their meaning without adding fake policy logic.
Constraint: Permission output must stay aligned with the real three-mode runtime policy already implemented
Rejected: Add richer permission-policy previews per tool | would require more UI surface and risks overstating current policy fidelity
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep permission-mode docs in the CLI consistent with normalize_permission_mode and permission_policy behavior
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual operator UX review of /permissions flows in a live REPL
Replace terse /model strings with sectioned model reports that show the active model and preserved session context, and use a structured switch report when the model changes. This keeps the behavior honest while making model management feel more intentional and Claude-like.
Constraint: Model switching must preserve the current session and avoid adding any fake model catalog or validation layer
Rejected: Add a hardcoded model list or aliases | would create drift with actual backend-supported model names
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep /model output informational and backend-agnostic unless the runtime gains authoritative model discovery
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual interactive switching across multiple real Anthropic model names
Require an explicit /clear --confirm flag before wiping live or resumed session state. This keeps the command genuinely useful while adding the minimal safety check needed for a destructive command in a chatty terminal workflow.
Constraint: /clear must remain a real functional command without introducing interactive prompt machinery that would complicate REPL input handling
Rejected: Add y/n interactive confirmation prompt | extra stateful prompting would be slower to ship and more fragile inside the line editor loop
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep destructive slash commands opt-in via explicit flags unless the CLI gains a dedicated confirmation subsystem
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual keyboard-driven UX pass for accidental /clear entry in interactive REPL
Reformat /status and /config into sectioned reports with stable labels so the CLI surfaces read more like a usable operator console and less like dense debug strings. This improves discoverability and parity feel without changing the underlying data model or inventing fake settings behavior.
Constraint: Output polish must preserve the exact locally discoverable facts already exposed by the CLI
Rejected: Add interactive /clear confirmation first | wording/layout polish was cleaner, lower-risk, and touched fewer control-flow paths
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep CLI reports sectioned and label-stable so future tests can assert on intent rather than fragile token ordering
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual terminal-width UX review for very long paths or merged JSON payloads
Expand /status so it reports the current working directory, whether the CLI is operating on a live REPL or resumed session file, how many Claude config files were loaded, and how many instruction memory files were discovered. This makes status feel more like an operator dashboard instead of a bare token counter while still only surfacing metadata we can inspect locally.
Constraint: Status must only report context available from the current filesystem and session state
Rejected: Include guessed project metadata or upstream-only fields | would make the status output look richer than the implementation actually is
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep status additive and local-truthful; avoid inventing context that is not directly discoverable
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual interactive comparison of REPL /status versus resumed-session /status
Improve top-level help and shared slash-command help so the implemented surface is easier to discover, with explicit resume-safe markings and concrete examples for saved-session workflows. This keeps the command registry authoritative while making the CLI feel less skeletal and more like a real operator-facing tool.
Constraint: Help text must reflect the actual implemented surface without advertising unsupported offline/runtime behavior
Rejected: Separate bespoke help tables for REPL and --resume | would drift from the shared command registry
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Add new slash commands to the shared registry first so help and resume capability stay synchronized
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual UX comparison against upstream Claude Code help output
Extend --resume so operators can run multiple safe slash commands in sequence against a saved session file, including mutating maintenance actions like /compact and /clear plus useful local /init scaffolding. This brings resumed sessions closer to the live REPL command surface without pretending unsupported runtime-bound commands work offline.
Constraint: Resumed sessions only have serialized session state, not a live model client or interactive runtime
Rejected: Support every slash command under --resume | model and permission changes do not affect offline saved-session inspection meaningfully
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep --resume limited to commands that can operate purely from session files or local filesystem context
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual interactive smoke test of chained --resume commands in a shell session
Add a genuinely useful /init command that creates a starter CLAUDE.md from the current repository shape without inventing unsupported setup flows. The scaffold pulls in real verification commands and repo-structure notes for this workspace, and it refuses to overwrite an existing CLAUDE.md.
This keeps the command honest and low-risk while moving the CLI closer to Claude Code's practical bootstrap surface.
Constraint: /init must be non-destructive and must not overwrite an existing CLAUDE.md
Constraint: Generated guidance must come from observable repo structure rather than placeholder text
Rejected: Interactive multi-step init workflow | too much unsupported UI/state machinery for this Rust CLI slice
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep generated CLAUDE.md templates concise and repo-derived; do not let /init drift into fake setup promises
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: manual /init invocation in a separate temporary repository without a preexisting CLAUDE.md
Improve resumed-session parity by letting top-level --resume execute shared read-only commands such as /help, /status, /cost, /config, and /memory in addition to /compact. This makes saved sessions meaningfully inspectable without reopening the interactive REPL.
Also add a genuinely useful /memory command that reports the Claude instruction memory already discovered by the runtime from CLAUDE.md-style files in the current directory ancestry. The command stays honest by surfacing file paths, line counts, and a short preview instead of inventing unsupported persistent memory behavior.
Constraint: Resume-path improvements must operate safely on saved sessions without requiring a live model runtime
Constraint: /memory must expose real repository instruction context rather than placeholder state
Rejected: Invent editable or persistent chat memory storage | no such durable feature exists in this repo yet
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Reuse shared slash parsing for resume-path features so saved-session commands and REPL commands stay aligned
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: manual resume against a diverse set of historical session files from real user workflows
Add in-REPL session restoration and read-only config inspection so the CLI can recover saved conversations and expose Claude settings without leaving interactive mode. /resume now reloads a session file into the live runtime, and /config shows discovered settings files plus the merged effective JSON.
The new commands stay on the shared slash-command surface and rebuild runtime state using the current model, system prompt, and permission mode so existing REPL behavior remains stable.
Constraint: /resume must update the live REPL session rather than only supporting top-level --resume
Constraint: /config should inspect existing settings without mutating user files
Rejected: Add editable /config writes in this slice | read-only inspection is safer and sufficient for immediate parity work
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep resume/config behavior on the shared slash command surface so non-REPL entrypoints can reuse it later
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: manual interactive restore against real saved session files outside automated fixtures
Expand the shared slash registry and REPL dispatcher with real session-management commands so the CLI feels closer to Claude Code during interactive use. /permissions now reports or switches the active permission mode, /clear rebuilds a fresh local session without restarting the process, and /cost reports cumulative token usage honestly from the runtime tracker.
The implementation keeps command parsing centralized in the commands crate and preserves the existing prompt-mode path while rebuilding runtime state safely when commands change session configuration.
Constraint: Commands must be genuinely useful local behavior rather than placeholders
Constraint: Preserve REPL continuity when changing permissions or clearing session state
Rejected: Store permission-mode changes only in environment variables | would not update the live runtime for the current session
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep future stateful slash commands rebuilding from current session + system prompt instead of mutating hidden runtime internals
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: manual live API session exercising permission changes mid-conversation
Centralize slash command parsing in the commands crate so the REPL can share help metadata and grow toward Claude Code parity without duplicating handlers. This adds shared /help and /model parsing, routes REPL dispatch through the shared parser, and upgrades /status to report model and token totals.
To satisfy the required verification gate, this also fixes existing workspace clippy and test blockers in runtime, tools, api, and compat-harness that were unrelated to the new command behavior but prevented fmt/clippy/test from passing cleanly.
Constraint: Preserve existing prompt-mode and REPL behavior while adding real slash commands
Constraint: cargo fmt, clippy, and workspace tests must pass before shipping command-surface work
Rejected: Keep command handling only in main.rs | would deepen duplication with commands crate and resume path
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Extend new slash commands through the shared commands crate first so REPL and resume entrypoints stay consistent
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: live Anthropic network execution beyond existing mocked/integration coverage
Wire the CLI to the Anthropic client, runtime conversation loop, and MVP in-tree tool executor so prompt mode and the default REPL both execute real turns instead of scaffold-only commands.
Constraint: Proxy auth uses ANTHROPIC_AUTH_TOKEN as the primary x-api-key source and may stream extra usage fields
Constraint: Must preserve existing scaffold commands while enabling real prompt and REPL flows
Rejected: Keep prompt mode on the old scaffold path | does not satisfy end-to-end CLI requirement
Rejected: Depend solely on raw SSE message_stop from proxy | proxy/event differences required tolerant parsing plus fallback handling
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep prompt mode tool-free unless the one-shot path is explicitly expanded and reverified against the proxy
Tested: cargo test -p api; cargo test -p tools; cargo test -p runtime; cargo test -p rusty-claude-cli; cargo build; cargo run -p rusty-claude-cli -- prompt "say hello"; printf '/quit\n' | cargo run -p rusty-claude-cli --
Not-tested: Full interactive tool_use roundtrip against the proxy in REPL mode
