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
