Gemini CLI is a terminal-based AI agent that lets developers interact with Google Gemini models and use tools for tasks such as file operations, shell commands, web fetching, and search. Developers use it from the command line, and the catalogue add-ons extend its workflows and integrations.
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.

What it costs to keep this loaded
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 5.1 | $0.00015 | $0.00664 |
| Opus 5.5 | $0.00006 | $0.00266 |
| Sonnet 5.5 | $0.00003 | $0.00133 |
| Haiku 4.5 | $0.00002 | $0.00066 |
Grade A, and why
effort scanned grade A with 1 finding 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 1mo 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.

Expected in a hook, worth knowing in a rule or an instructions file.

Effort Estimator Instructions
Analyze the issue content (title, body) AND the code exploration output (the discovered source files, coupled UI components, and test files) to estimate the effort required to implement a fix.
JSON Output Format:
{
"effort_estimate": "SMALL" | "MEDIUM" | "LARGE",
"effort_reasoning": "Detailed explanation of why this estimate was chosen."
}
Effort Levels:
SMALL (1 day or less):
- Trivial Logic & Config: Schema updates (Zod), feature flag toggles, adding missing fields to package.json or settings.json.
- UI/Aesthetic Adjustments: Fixing minor layout bugs in Ink components (e.g., adding flexShrink, correcting padding in a single Box), text color changes.
- Documentation & Strings: Typos, log message updates, CLI argument descriptions.
- Localized Bug Fixes: Single-file logic errors, straightforward promise rejections (e.g., wrapping a known failure in a try/catch), simple regex or string parsing fixes.
- Unhandled Errors with Obvious Fixes: Issues with provided stack traces or obvious offending lines where the root cause and fix are clear. MEDIUM (2-3 days):
- React/Ink State Management: Complex component lifecycle issues (memory leaks in the UI), terminal redraw flickering, or state synchronization between the CLI's internal input buffer and the interactive React components.
- Asynchronous Flow & Integration: Resolving complex Promise chains, ERR_STREAM_PREMATURE_CLOSE, debugging IDE companion extensions (VS Code, Android Studio) or resolving hanging HTTP requests/IPC between the CLI and external plugins, timeouts in non-interactive/ACP modes.
- Tooling & Output Parsers: Modifying how tools parse streaming stdout/stderr buffers, adding new built-in tools that don't require native bindings.
- Cross-Component & Cross-Package Refactors: Any fix or change that spans across packages/cli and packages/core (such as unifying event handlers, hooks, or UI state across package boundaries). LARGE (3+ days):
- Platform-Specific Complexities (PTY/Signals): Any issue involving node-pty, child_process.spawn, pseudo-terminal exhaustion (ENXIO), raw mode terminal desyncs, or POSIX signal forwarding (SIGINT/SIGTERM).
- Core Architecture & Protocols: Refactoring the Scheduler, Agent-to-Agent (A2A) protocol implementation, low-level MCP (Model Context Protocol) transport mechanisms.
- CI/CD Infrastructure Overhauls: Major redesign of release pipelines or runner execution environments with a large blast radius across production builds.
- Performance & Memory: Diagnosing massive disk/memory leaks, severe boot time regressions, high-throughput streaming optimizations (e.g., voice streaming pipelines).
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.

effort is a skill published in the GitHub repository google-gemini/gemini-cli (108,582 stars, last pushed today), licensed Apache-2.0. It adds 15 tokens to every session and 664 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
