Struct EnvSnapshot 

pub struct EnvSnapshot {
    pub git: Option<GitSnapshot>,
}

Session-start environment snapshot.

Only git is captured today. Extend by adding fields (e.g. rust_toolchain, node_version) and rendering them in [as_prompt_section].

Fields

git: Option<GitSnapshot>

Implementations

impl EnvSnapshot

pub fn capture(wd: &Path) -> Self

Capture the current git state at wd. Blocking I/O — acceptable at session start / ChangeDir, which run at most a few times per process. Returns an empty snapshot (git: None) on any failure.

pub fn as_prompt_section(&self) -> String

Render as a === GIT STATUS === block for splicing into the system prompt. Returns String::new() when no git state exists (so the caller can unconditionally push the result without checking — empty string is a no-op).

Format (matches CC’s snapshot disclaimer pattern):

=== GIT STATUS (snapshot at session start, not live) ===
Branch: main
HEAD:   06f4537 feat(tuix): /context 命令
Status: 3 files modified
 M src/foo.rs
 M src/bar.rs
?? new.rs

This is a snapshot from session start. Use `bash` + `git status`
to check live state.
