Plannotator is a local browser-based review tool for coding agents that lets people annotate plans, documents, HTML artifacts, code diffs, and pull requests, then send feedback back to the agent. It is used by developers and teams reviewing work from agents across supported coding tools and version-control systems.
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.
git clone --depth 1 https://github.com/backnotprop/plannotatorWrote this? Show the measurements
A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Only the verdict fits; the numbers stay here.

plannotator 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 today.
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 it actually says
{
"name": "plannotator",
"description": "Interactive Plan Review: Mark up and refine your plans using a UI, easily share for team collaboration, automatically integrates with plan mode hooks.",
"version": "0.28.21",
"author": {
"name": "backnotprop"
},
"repository": "https://github.com/backnotprop/plannotator",
"keywords": ["planning", "review", "hooks", "ExitPlanMode", "collaboration"]
}
What it installs
The manifest is a name and a version. 2 hooks travel with it, and installing the plugin installs all of them. Each is measured on its own page, and each can be installed alone.
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.
