## Why
Developers are frequently running low on disk space, and routine use of
`--all-features` contributes to larger Cargo build caches in `target/`
by compiling additional feature combinations.
This change updates local workflow guidance to avoid `--all-features` by
default and reserve it for cases where full feature coverage is
specifically needed.
## What Changed
- Updated `AGENTS.md` guidance for `codex-rs` to recommend `cargo test`
/ `just test` for full-suite local runs, and to call out the disk-usage
cost of routine `--all-features` usage.
- Updated the root `justfile` so `just fix` and `just clippy` no longer
pass `--all-features` by default.
- Updated `docs/install.md` to explicitly describe `cargo test
--all-features` as an optional heavier-weight run (more build time and
`target/` disk usage).
## Verification
- Confirmed the `justfile` parses and the recipes list successfully with
`just --list`.
## What
Updates the optional `cargo-nextest` install command in
`docs/install.md`:
- `cargo install cargo-nextest` -> `cargo install --locked
cargo-nextest`
## Why
The current docs command can fail during source install because recent
`cargo-nextest` releases intentionally require `--locked`.
Repro (macOS, but likely not platform-specific):
- `cargo install cargo-nextest`
- Fails with a compile error from `locked-tripwire` indicating:
- `Nextest does not support being installed without --locked`
- suggests `cargo install --locked cargo-nextest`
Using the locked command succeeds:
- `cargo install --locked cargo-nextest`
## How
Single-line docs change in `docs/install.md` to match current
`cargo-nextest` install requirements.
## Validation
- Reproduced failure locally using a temporary `CARGO_HOME` directory
(clean Cargo home)
- Example command used: `CARGO_HOME=/tmp/cargo-home-test cargo install
cargo-nextest`
- Confirmed success with `cargo install --locked cargo-nextest`
Adds a top-level `log_dir` config key (defaults to `$CODEX_HOME/log`) so
one-off runs can redirect `codex-tui.log` via `-c`, e.g.:
codex -c log_dir=./.codex-log
Also resolves relative paths in CLI `-c/--config` overrides for
`AbsolutePathBuf` values against the effective cwd (when available).
Tests:
- cargo test -p codex-core
This eliminates redundant user documentation and allows us to focus our
documentation investments.
I left tombstone files for most of the existing ".md" docs files to
avoid broken links. These now contain brief links to the developers docs
site.
Update install and contributing guides to use the root justfile helpers
(`just fmt`, `just fix -p <crate>`, and targeted tests) instead of the
older cargo fmt/clippy/test instructions that have been in place since
459363e17b. This matches the justfile relocation to the repo root in
952d6c946 and the current lint/test workflow for CI (see
`.github/workflows/rust-ci.yml`).
Apparently we were not running our `pnpm run prettier` check in CI, so
many files that were covered by the existing Prettier check were not
well-formatted.
This updates CI and formats the files.
This PR cleans up the monolithic README by breaking it into a set
navigable pages under docs/ (install, getting started, configuration,
authentication, sandboxing and approvals, platform details, FAQ, ZDR,
contributing, license). The top‑level README is now more concise and
intuitive, (with corrected screenshots).
It also consolidates overlapping content from codex-rs/README.md into
the top‑level docs and updates links accordingly. The codex-rs README
remains in place for now as a pointer and for continuity.
Finally, added an extensive config reference table at the bottom of
docs/config.md.
