gemini-prompting

gemini-prompting is a skill for Claude Code from spyrae/gemini-plugin-cc. It costs 16 tokens per session (387 once invoked), scanned A, original, Apache-2.0.

A prompt-writing guide for Gemini CLI, a command-line tool that runs Gemini coding tasks. It recommends including the task, project context, constraints, expected files, and a way to verify completion.

In plain words
What is it for?
Use it when sending debugging, feature, or code-change work to Gemini through the rescue command.
Why use it?
It helps turn vague requests into prompts that another coding agent can act on and check. It also discourages combining unrelated tasks in one request.

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

gemini-prompting 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 2mo 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.

What it actually says

Gemini Prompting Guide

When delegating tasks to Gemini via /gemini:rescue, structure the prompt effectively.

Prompt structure

TASK: [One sentence — what to achieve]

CONTEXT:
- Project type: [language/framework]
- Relevant files: [list key files]
- Current state: [what's working, what's broken]

CONSTRAINTS:
- [Patterns to follow]
- [Things that must not change]
- [Dependencies available]

EXPECTED OUTPUT:
- [What files to create/modify]
- [What the result should look like]
- [How to verify success]

Best practices

  1. Be specific about files. Gemini doesn't know the codebase. Name the exact files and functions to modify.

  2. Include error context. If debugging, paste the actual error message and stack trace.

  3. Specify the framework. "Fix the Flutter test" is better than "fix the test". "Add a Riverpod provider" is better than "add state management".

  4. Define done. What command should pass for the task to be complete? "Tests pass with flutter test" or "Build succeeds with npm run build".

  5. One task per prompt. Don't combine "fix the bug AND refactor the module AND add tests". Split into separate rescue calls.

Anti-patterns

  • Vague prompts: "make it better" — better: "reduce the function from 80 lines to under 40 by extracting helpers"
  • No context: "fix the auth" — better: "fix the JWT refresh in lib/auth.dart — it throws 401 on expired tokens"
  • Too broad: "rewrite the app" — break into phases
Changes

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.
