agent-preflight

agent-preflight is a command for Claude Code from ccplugins/awesome-claude-code-plugins. It costs 12 tokens per session (365 once invoked), scanned A, original, Apache-2.0.

A local repository check that runs before a coding agent receives broad access to your project. It reviews the current branch, changes, and files for safety risks.

In plain words
What is it for?
Use it at the start of an AI-assisted coding session to inspect repository risks and produce rules for allowed commands, approval-required commands, and off-limits files.
Why use it?
It helps identify risky files or commands before the agent can act. This makes it clearer what the agent may do, what needs approval, and what it must avoid.

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

agent-preflight scanned grade A with 1 finding 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.

What it actually says

Context

  • Current branch: !git branch --show-current
  • Current status: !git status --short

Your task

Run an AI-agent safety preflight before this Claude Code session gets broad tool access.

  1. If agent_preflight_lite.py is present in this repo, run:

    python3 agent_preflight_lite.py .
    python3 agent_preflight_lite.py . --json
    
  2. Summarize the result as Green, Yellow, or Red:

    • Green: zero or one low-risk bucket; continue with normal review discipline.
    • Yellow: two or three buckets, package scripts, MCP/Claude/Cursor config, or secret-adjacent files; write may-run / must-ask / must-not-touch rules before executing commands.
    • Red: destructive shell, credential-adjacent files, or four-plus risk buckets; stop and get explicit approval before shell/package/deploy commands.
  3. If the scanner is missing, do not curl-pipe or auto-install anything. Tell the user to inspect or copy the free scanner from: https://github.com/el-zachariah/ai-agent-safety-starter-pack

  4. End with a concise handoff:

    • Findings
    • Commands allowed now
    • Commands that need approval
    • Files or directories the agent must not touch

This command is a lightweight pre-tool-access checklist for Claude Code plugin users; it is not a sandbox, malware scanner, or full security audit.

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.
