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 | $0.01084 | $0.01084 |
| Opus 5 | $0.00542 | $0.00542 |
| Sonnet 5 | $0.00217 | $0.00217 |
| Haiku 4.5 | $0.00108 | $0.00108 |
Grade A, and why
gemini-cli-googleadsagent GEMINI.md scanned grade A with 0 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Gemini CLI Project Context
Gemini CLI is an open-source AI agent that brings the power of Gemini directly into the terminal. It is designed to be a terminal-first, extensible, and powerful tool for developers.
Project Overview
- Purpose: Provide a seamless terminal interface for Gemini models, supporting code understanding, generation, automation, and integration via MCP (Model Context Protocol).
- Main Technologies:
- Runtime: Node.js (>=20.0.0, recommended ~20.19.0 for development)
- Language: TypeScript
- UI Framework: React (using Ink for CLI rendering)
- Testing: Vitest
- Bundling: esbuild
- Linting/Formatting: ESLint, Prettier
- Architecture: Monorepo structure using npm workspaces.
packages/cli: User-facing terminal UI, input processing, and display rendering.packages/core: Backend logic, Gemini API orchestration, prompt construction, and tool execution.packages/core/src/tools/: Built-in tools for file system, shell, and web operations.packages/a2a-server: Experimental Agent-to-Agent server.packages/vscode-ide-companion: VS Code extension pairing with the CLI.
Building and Running
- Install Dependencies:
npm install - Build All:
npm run build:all(Builds packages, sandbox, and VS Code companion) - Build Packages:
npm run build - Run in Development:
npm run start - Run in Debug Mode:
npm run debug(Enables Node.js inspector) - Bundle Project:
npm run bundle - Clean Artifacts:
npm run clean
Testing and Quality
- Test Commands:
- Unit (All):
npm run test - Integration (E2E):
npm run test:e2e - Workspace-Specific:
npm test -w <pkg> -- <path>(Note:<path>must be relative to the workspace root, e.g.,-w @google/gemini-cli-core -- src/routing/modelRouterService.test.ts)
- Unit (All):
- Full Validation:
npm run preflight(Heaviest check; runs clean, install, build, lint, type check, and tests. Recommended before submitting PRs. Due to its long runtime, only run this at the very end of a code implementation task. If it fails, use faster, targeted commands (e.g.,npm run test,npm run lint, or workspace-specific tests) to iterate on fixes before re-runningpreflight. For simple, non-code changes like documentation or prompting updates, skippreflightat the end of the task and wait for PR validation.) - Individual Checks:
npm run lint/npm run format/npm run typecheck
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.
