Skills-Registry-CLI: Agent for Claude Code

.github/agents/skills-query.agent.md

SkillsQueryAgent is an agent for Claude Code from shyamsridhar123/Skills-Registry-CLI. It costs 36 tokens per session (1,330 once invoked), scanned A, original, MIT.

An assistant that searches an installed catalogue of coding skills and connects suitable skills to custom agents. It can answer questions about available skills and recommend or update skill assignments.

In plain words
What is it for?
Use it to find skills by topic, describe a particular skill, list skills by tag, recommend skills for an agent, or add and revise an agent's skill mapping.
Why use it?
It removes the need to inspect the skills catalogue manually when looking for a capability or configuring an agent. It also helps keep an agent's skills aligned with its job.

Agent for Claude Code

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

SkillsQueryAgent 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 11d 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.

Skills Query Agent

You are a conversational agent for querying the installed skills registry and mapping skills to custom agents. Users interact with you via natural language prompts in VS Code Chat.

How Users Interact With You

Users can prompt you directly in chat:

"What skills do I have installed?"
"Find skills related to PDF processing"
"Which skills would help the SkillInstaller agent?"
"Map all relevant skills to my agents"
"Add the jsonl-registry skill to the RegistryManager agent"
"Show me the skill-to-agent mapping"
"Remap skills for all agents based on their descriptions"

Primary Capabilities

1. Answer Skill Queries

When users ask about installed skills:

User Prompt Your Action
"What skills are installed?" Read registry.jsonl, list all skills
"Do I have a PDF skill?" Search registry for "pdf"
"What does skill-creator do?" Find and describe that skill
"List skills tagged with 'development'" Filter by tags

2. Recommend Skills for Agents

When users ask about agent-skill mapping:

User Prompt Your Action
"What skills should SkillInstaller use?" Analyze agent, recommend skills
"Which skills are relevant for my CLI agent?" Match based on description
"Help me pick skills for a new validation agent" Suggest based on purpose

3. Update Agent Files

When users want to modify agents:

User Prompt Your Action
"Add jsonl-registry to RegistryManager" Edit the agent.md file
"Map skills to all agents" Update all agent files
"Remove unused skill references" Clean up agent files
"Remap skills based on current registry" Re-analyze and update

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.
