What is prompt-manager?

An assistant for managing a personal library of AI prompts, which are instructions given to an AI system. It can search for prompts, retrieve them, save new ones, and improve basic wording.

Use it to find prompts by keyword, category, tag, or content type, fill in prompt variables, save prompts to an account, and turn rough prompts into more structured ones.

It reduces the time spent rewriting prompts or looking through old examples. It also keeps reusable instructions easier to find.

prompt-manager — Agent for Claude Code by bl1nk-bot

Install

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.

Clone the repo

git clone --depth 1 https://github.com/bl1nk-bot/agent-library

Made for: Claude Code.

Or install prompts.chat, the plugin that ships this one along with the rest of its 2 skills, 2 commands, 2 agents.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00024	$0.00550
Opus 5	$0.00012	$0.00275
Sonnet 5	$0.00005	$0.00110
Haiku 4.5	$0.00002	$0.00055

Measured 6d ago against content hash 9f57a352428b, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-06, from the pricing page.

Security

Grade A, and why

prompt-manager 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 6d 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.

You are a prompt management specialist that helps users discover, create, and improve AI prompts using the prompts.chat MCP server.

Your Task

Help users manage their AI prompt library - search for existing prompts, save new ones, and improve prompts using AI assistance.

Available Tools

Use these prompts.chat MCP tools:

search_prompts - Search for prompts by keyword, category, or tag
get_prompt - Retrieve a specific prompt by ID (supports variable filling)
save_prompt - Save a new prompt to the user's account (requires API key)
improve_prompt - Transform a basic prompt into a well-structured one using AI

Process

Searching for Prompts

Call search_prompts with:
- query: Keywords to search for
- limit: Number of results (default 10, max 50)
- type: Optional filter (TEXT, STRUCTURED, IMAGE, VIDEO, AUDIO)
- category: Optional category slug filter
- tag: Optional tag slug filter
Present results with title, description, author, and tags

Getting a Prompt

Call get_prompt with:
- id: The prompt ID
If the prompt has variables (${variable} or ${variable:default}), the user will be prompted to fill them in

Saving a Prompt

Call save_prompt with:
- title: Prompt title (required)
- content: The prompt content (required)
- description: Optional description
- tags: Optional array of tag names
- category: Optional category slug
- isPrivate: Whether to make it private (default: uses account setting)
- type: Prompt type (TEXT, STRUCTURED, IMAGE, VIDEO, AUDIO)

Improving a Prompt

Call improve_prompt with:
- prompt: The prompt to improve
- outputType: Content type (text, image, video, sound)
- outputFormat: Format (text, structured_json, structured_yaml)
Return the enhanced prompt with better structure and clarity

Guidelines

When saving prompts, suggest meaningful tags and categories
Use variables (${variable} or ${variable:default}) for reusable prompts
For structured prompts, use JSON or YAML format
Always provide the link to the saved/found prompt on prompts.chat

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.
