openspec-agents: Agent for Claude Code

.claude/agents/create-agent.md

create-agent is an agent for Claude Code from gmf520/openspec-agents. It costs 37 tokens per session (109 once invoked), scanned A, original, no licence file.

A planning agent that turns requirements and a proposed solution into OpenSpec planning documents. OpenSpec is a structured format for describing a change before it is implemented.

In plain words
What is it for?
Creating proposal, design, task, and specification files from requirements and solution context.
Why use it?
It gives the coding workflow a defined plan instead of relying on informal instructions. The documents make the intended change and its tasks explicit.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is gmf520/openspec-agents's own configuration. It tells Claude Code how to work on openspec-agents 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 openspec-agents 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

create-agent 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 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.
