Plan is for full CoT summaries to be visible in a "transcript view" when we implement that, but for now they're hidden. https://github.com/user-attachments/assets/e8a1b0ef-8f2a-48ff-9625-9c3c67d92cdb

To get started, describe a task or try one of these commands:
|
||
|
||
/init - create an AGENTS.md file with instructions for Codex
|
||
/status - show current session configuration and token usage
|
||
/approvals - choose what Codex can do without approval
|
||
/model - choose what model and reasoning effort to use
|
||
|
||
codex
|
||
I’m going to scan the workspace and Cargo manifests to see build profiles and
|
||
dependencies that impact binary size. Then I’ll summarize the main causes.

codex
|
||
Here’s what’s driving size in this workspace’s binaries.
|
||
|
||
Main Causes
|
||
|
||
- Static linking style: Each bin (codex, codex-tui, codex-exec,
|
||
codex-mcp-server, etc.) statically links its full dependency graph, so common
|
||
code isn’t shared at runtime across executables.
|
||
- Heavy deps (HTTP/TLS): reqwest brings in Hyper, HTTP/2, compressors, and a TLS
|
||
stack (rustls by default; OpenSSL on musl). In core, login, tui, and ollama you
|
||
enable reqwest with json/stream, which still pulls a large transitive set.
|
||
- Image/terminal stack: codex-tui includes image (with jpeg), ratatui,
|
||
crossterm, and ratatui-image, which together contribute significant code size
|
||
(decoders, pixel ops, terminal backends).
|
||
- Parsers/VMs: tree-sitter + tree-sitter-bash (in core and apply-patch) and
|
||
starlark (in execpolicy) include sizeable parser/VM tables and runtimes.
|
||
- Tokio runtime: Broad tokio features (rt-multi-thread, macros, process, signal)
|
||
across many crates inflate code size even if only subsets are used per bin.
|
||
- Panic + backtraces: Default panic = unwind and backtrace support keep
|
||
unwinding tables and symbols that add weight.
|
||
- Per-target OpenSSL (musl): For *-unknown-linux-musl, core enables openssl-sys
|
||
with vendored, compiling OpenSSL into the binary—this adds multiple megabytes
|
||
per executable.
|
||
|
||
Build-Mode Notes
|
||
|
||
- Release settings: You use lto = "fat" and codegen-units = 1 (good for size),
|
||
but strip = "symbols" keeps debuginfo. Debuginfo is often the largest single
|
||
contributor; if you build in release with that setting, binaries can still be
|
||
large.
|
||
- Debug builds: cargo build (dev profile) includes full debuginfo, no LTO, and
|
||
assertions—outputs are much larger than cargo build --release.
|
||
|
||
If you want, I can outline targeted trims (e.g., strip = "debuginfo", opt-level
|
||
= "z", panic abort, tighter tokio/reqwest features) and estimate impact per
|
||
binary.
