Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00486 | $0.00486 |
| Opus 5 | $0.00243 | $0.00243 |
| Sonnet 5 | $0.00097 | $0.00097 |
| Haiku 4.5 | $0.00049 | $0.00049 |
Grade B, and why
rag_for_git GEMINI.md scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
This registers the MCP server in `~/.gemini/settings.json` automatically (cross-platform, Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

rag_for_git — Gemini CLI context
See CLAUDE.md for full project documentation (architecture, commands, invariants).
MCP server setup
Quickest way
uvx --from rag-reviewer reviewer install gemini
This registers the MCP server in ~/.gemini/settings.json automatically (cross-platform,
uses the absolute path to uvx — no bash -lc wrapper needed).
Global config (manual alternative)
Add to ~/.gemini/settings.json under "mcpServers":
{
"mcpServers": {
"reviewer": {
"command": "/bin/bash",
"args": ["-lc", "uvx --from rag-reviewer@latest reviewer-mcp"]
}
}
}
The bash -lc wrapper loads your shell profile so uvx (in ~/.local/bin) is found
by GUI tools that don't inherit the full shell PATH (macOS/Linux only; on Windows use
reviewer install gemini or set command to uvx directly).
Project-level config
.gemini/settings.json in this repo already contains the MCP entry — Gemini CLI
picks it up automatically when you open this project.
Skills
Gemini CLI discovers skills from .gemini/skills/ (project) or ~/.gemini/skills/ (global).
Install globally — no repo clone needed:
curl -sL https://github.com/mimfort/rag_for_git/archive/refs/heads/main.tar.gz -o /tmp/rag-reviewer.tgz
mkdir -p ~/.gemini/skills
tar xz -C ~/.gemini/skills --strip-components=3 -f /tmp/rag-reviewer.tgz 'rag_for_git-main/plugin/skills'
rm /tmp/rag-reviewer.tgz
Skills installed: review-pr, solve-task, sync-codebase, sync-tasks,
performance-review, maintainability-review.
Then use them: use skill rag-reviewer:review-pr
Verify
After restarting Gemini CLI, run:
"List available MCP tools"
You should see mcp_reviewer_prepare_review, mcp_reviewer_publish_review, etc.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

rag_for_git GEMINI.md is an instructions file published in the GitHub repository mimfort/rag_for_git (21 stars, last pushed 3d ago), licensed MIT. It adds 486 tokens to every session, about $0.0024 per session on Opus 5. A static security scan graded it B with 2 findings (reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
