agent-library: Command for Gemini CLI

.gemini/commands/prompt-suggest.toml

prompt-suggest is a command for Gemini CLI from bl1nk-bot/agent-library. It costs 0 tokens per session (263 once invoked), scanned A, a copy of prompt-suggest, CC0-1.0.

A prompt-analysis command that studies an agent's behavior and suggests broad improvements to its system instructions. System instructions are the rules that guide an AI agent's responses and actions.

In plain words
What is it for?
Use it to analyze a specific failure and propose generalized changes to the agent's prompts.
Why use it?
It helps identify when unclear or overly narrow instructions are causing an agent to behave incorrectly.

Command for Gemini CLI

Written for Gemini CLI: installed under .gemini/.

This is bl1nk-bot/agent-library's own configuration. It tells Gemini CLI how to work on agent-library itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-library configures →

Token cost

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.

Security

Grade A, and why

prompt-suggest 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 5d 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.

Origin

This is a copy

100% identical to prompt-suggest — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

description = "Analyze agent behavior and suggest high-level improvements to system prompts." prompt = """

Prompt Engineering Analysis

You are a world-class prompt engineer and an expert AI engineer at the top of your class. Your goal is to analyze a specific agent behavior or failure and suggest high-level improvements to the system instructions.

Observed Behavior / Issue: {{args}}

Reference Context:

  • System Prompt Logic: @packages/core/src/core/prompts.ts

Task

  1. Analyze the Failure: Review the provided behavior and identify the underlying instructional causes. Use the /introspect command output if provided by the user.
  2. Strategic Insights: Share your technical view of the issue. Focus on the "why" and identify any instructional inertia or ambiguity.
  3. Propose Improvements: Suggest high-level changes to the system instructions to prevent this behavior.

Principles

  • Avoid Hyper-scoping: Do not create narrow solutions for specific scenarios; aim for generalized improvements that handle classes of behavior.
  • Avoid Specific Examples in Suggestions: Keep the proposed instructions semantic and high-level to prevent the agent from over-indexing on specific cases.
  • Maintain Operational Rigor: Ensure suggestions do not compromise safety, security, or the quality of the agent's work. """

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.
