guard

guard is an agent for Claude Code from lisihao/Solar. It costs 9 tokens per session (233 once invoked), scanned A, original, MIT.

A strict code-checking guide that reviews coding conventions, version completeness, and performance-related safeguards. It reports either pass or block, with issues including the affected file, line, and message.

In plain words
What is it for?
Use it to inspect code changes for required files, references, optimizations, and build configuration updates. It is designed to block work when a listed check fails.
Why use it?
It catches hard-coded values or paths, leaked sensitive information, deleted operator files, outdated references, missing SIMD or Neon code, and unupdated CMake files before work is accepted.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

Good fit Use it to inspect code changes for required files, references, optimizations, and build configuration updates. It is designed to block work when a listed check fails.

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

guard 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 1mo 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.
