| description | Disable Claude Code built-in git instructions and inject a curated 280-tok minimum via SessionStart hook. Saves ~2,200 tok/session + ~1,700 tok/call. |
| when_to_use | AI may auto-invoke for SAFE subcommands only — dismiss-banner, undismiss-banner, status, help.
AI MUST NOT auto-invoke DESTRUCTIVE subcommands — install, revert.
Destructive subcommands require the user to explicitly type the slash command.

Manage Claude Code's built-in includeGitInstructions token consumption.
Subcommand routing
Parse the first argument from $ARGUMENTS:
| Subcommand | Risk | AI-allowed | Behavior |
|---|
install | 🔴 destructive | ❌ user-only | Modifies ~/.claude/settings.json + shell profile. Requires explicit <command-name>claude-code-token-saver:setup-git-lite</command-name> tag with <command-args>install</command-args> |
revert | 🔴 destructive | ❌ user-only | Aggressive cleanup. Same gating as install |
status | 🟢 safe | ✅ allowed | Read-only diagnostic |
dismiss-banner | 🟢 safe | ✅ allowed | Suppresses the recommendation banner (preferences.json flag) |
undismiss-banner | 🟢 safe | ✅ allowed | Re-enables the banner |
help | 🟢 safe | ✅ allowed | Prints usage |
| (empty) | 🟢 safe | ✅ allowed | Run status, then append one-line usage hint: "Subcommands: install, revert, status, dismiss-banner, undismiss-banner, help" |
Invocation guard — enforce for destructive subcommands only
If the subcommand is install or revert:
-
Verify explicit invocation: the triggering user message MUST contain <command-name>claude-code-token-saver:setup-git-lite</command-name> along with <command-args>install</command-args> (or revert). If these tags are absent (i.e., you inferred the intent from natural-language context), STOP and respond:
"This action modifies your global Claude Code settings and shell profile. Please invoke explicitly by typing /setup-git-lite install (or revert)."
-
User confirmation before execution: even when the tag is present, print a one-line summary and ask for a literal "yes":
"Install will:
- Set
includeGitInstructions: false in ~/.claude/settings.json
- Append a marker block to your shell profile exporting CLAUDE_CODE_DISABLE_GIT_INSTRUCTIONS=1
Proceed? (type yes to confirm)"
Only proceed on a literal yes. Any other response — cancel.
Safe subcommands (status, dismiss-banner, undismiss-banner, help) skip the guard entirely.
Execution
After (if required) passing the guard + confirmation, run:
node ${CLAUDE_PLUGIN_ROOT}/scripts/setup-git-lite.js <subcommand>
Relay stdout verbatim to the user. On non-zero exit, surface stderr.
Language
Detect the user's language from the conversation. Translate ALL user-facing output into that language. The script outputs English — you MUST translate before relaying. Keep technical identifiers verbatim (file paths, env var names, command names, setting keys).
Output conventions
status: translate stdout into the user's language, then relay.install: translate stdout, then add a short line pointing to README for the rationale.revert: translate stdout, then note "Your current shell env may still have the variable set — restart the shell or run unset CLAUDE_CODE_DISABLE_GIT_INSTRUCTIONS." (in the user's language).dismiss/undismiss: translate stdout, then relay.help: translate stdout, then relay.
Error handling
- Exit code 1 (general error): print stderr, suggest running
status.
- Exit code 2 (unknown subcommand): surface the hint from the script, no further work.
Design reference
The hook content and behavior are documented in the claude-code-token-saver README (Git instructions section). Key points for the user if they ask:
- Original CC built-in injects ~2,200 tokens per session (git status snapshot + full commit/PR workflow).
- Our replacement is ~280 tokens (11 override rules + compact git state line with file list).
- 88% token reduction, 95%+ of the safety rules preserved.
- Other style/workflow guidance is dropped because Claude's training already covers it (e.g., PR title conventions, HEREDOC format awareness, gh usage).
