Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔴 Critical · up to The CLI migration currently does not compile and also contains unresolved compatibility and behavior issues, including an incompatible Rust-version requirement and changes to option conflicts, help output, and frozen-mode handling; merging would block or regress the product.

Greptile SummaryThe PR completes the production CLI migration from clap to the pinned usage-rs stack while preserving command dispatch, validation, help, completion, and command-effect generation.
Confidence Score: 5/5The PR appears safe to merge from the perspective of the previously reported failures. No blocking failure from the previous review remains: the production migration is complete, the isolated shadow target is gone, the CI skip is accepted by the final gate, and the temporary MSRV change is explicitly deferred for this non-mergeable experiment.

In `@Cargo.toml`:
- Around line 75-76: Retain the direct clap dependency in Cargo.toml while
crates/aube/src/lib.rs still uses clap::Command, CommandFactory, and
FromArgMatches; remove it only after those paths are migrated to usage-rs APIs
and cargo check -p aube succeeds.
In `@crates/aube/src/commands/access.rs`:
- Around line 6-17: Complete the usage_derive migration by replacing the Clap
APIs in crates/aube/src/lib.rs (Cli::command, Cli::from_arg_matches, and
Cli::try_parse_from) with the usage-argv parser and removing unsupported
disable_version_flag. Update the argument definitions in
crates/aube/src/commands/access.rs lines 6-17, ci.rs lines 21-33, dedupe.rs
lines 12-23, doctor.rs lines 36-39, exec.rs lines 5-70, find_hash.rs lines
36-49, ignored_builds.rs lines 31-34, import.rs lines 3-13, recursive.rs lines
4-7, remove.rs lines 5-31, root.rs lines 20-23, and run.rs lines 7-110 to use
only supported usage_derive declarations; alternatively consistently restore
Clap derives and declarations across every listed site.
Apply the same fix in `@crates/aube/src/commands/run.rs` at line 7.
In `@crates/aube/src/commands/config/mod.rs`:
- Around line 27-55: ConfigArgs and ConfigCommand currently rely on unsupported
usage_derive integration and must be made compatible with the usage migration.
Switch these derives and attributes to a supported usage revision/API, or defer
this conversion until compatibility is available, and verify the result with
cargo check -p aube.
Apply the same fix in `@crates/aube/src/commands/update.rs` around lines 21 - 119:
Same documented merge-blocking compilation failure.
Apply the same fix in `@crates/aube/src/commands/install/args.rs` around lines 3 -
180: Same usage compatibility failure across migrated command argument types.
In `@crates/aube/src/commands/diag.rs`:
- Around line 45-48: Update the f64 CLI field attributes in the diag command,
including min_delta_ms and the adjacent percentage-change field, replacing
default_value_t with default string values "50.0" and "10.0" respectively so the
pinned usage-derive version can compile.
In `@crates/aube/src/commands/peers.rs`:
- Around line 34-52: Restore the peers check help examples currently held in
CHECK_AFTER_LONG_HELP by attaching them through the supported usage-derive help
mechanism for PeersCheckArgs or the Check subcommand. Ensure `aube peers check
--help` still displays the success, failure, and JSON examples, and remove no
longer-unused help content only if the examples are moved into supported
documentation.

Summary
Status
The conversion compiles, all 808 aube library tests pass, and aube clippy passes. This remains an experimental pre-6.x PR because it intentionally uses git revisions and contains documented workarounds for remaining usage launch gaps such as cross-flatten relationships, dynamic embedder identity, help topology, and MSRV tiers. It is not intended to merge before usage 6.x is published.
Validation
cargo check -p aubecargo test -p aube --lib --no-fail-fastcargo clippy -p aube --all-targets -- -D warningscargo fmt --allgit diff --checkThis PR description was generated by Codex.
Note
High Risk
Touches all CLI parsing/help/completions and raises MSRV; experimental git pins and documented usage 6.x gaps mean behavior and embedder builds can diverge until usage publishes.
Overview
Major experimental CLI stack change: the typed
aubecommand surface moves from clap to usage-rs (git-pinnedusagerev), with clap removed from the runtime graph. Workspace and internal crates bump to 2.0.0; MSRV rises to Rust 1.95 because derived KDL for effects/completions still goes through usage-lib.CI: the
cache-qualificationjob only runs when repo varAUBE_CACHE_QUALIFICATION_RUSTis1.95(experimental cache compiler still on 1.94); thefinalgate treats a skippedcache-qualificationas OK when that var is unset.Adds
USAGE_6_MIGRATION.mddocumenting pre-6.x gaps (post-bind validation, help headings, embedder naming, permissive root for forwarded PM commands).Reviewed by Cursor Bugbot for commit 3a5b050. Bugbot is set up for automated code reviews on this repo. Configure here.
