## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 0.26.4
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

Source inspection confirms a package-aligned OpenCode plan-review integration with an automatic command-copy hook and runtime permission configuration. These are non-malicious but warrant a warning under the extension-lifecycle policy.

## Latest scan

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Installation writes Plannotator-owned OpenCode command definitions to the user's OpenCode command directory. At runtime the plugin registers a plan-review tool and adjusts its OpenCode agent permissions; optional review/share functions use package-aligned endpoints.

- **Trigger:** npm postinstall; then OpenCode loads the configured plugin or the user invokes its review commands.

- **Impact:** Changes the OpenCode command/control surface for this extension and can process user-selected plan or URL content; no malicious execution or exfiltration chain was confirmed.

- **Evidence paths:** package.json, dist/index.js, dist/server.js, dist/embedded.js, commands/plannotator-review.md, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-08-10T08:23:53.126Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** OpenCode extension setup, plan-review tooling, and optional share/URL annotation.

- **Rationale:** Source inspection confirms a package-aligned OpenCode plan-review integration with an automatic command-copy hook and runtime permission configuration. These are non-malicious but warrant a warning under the extension-lifecycle policy.

- **Files touched:** ${XDG\_CONFIG\_HOME:-$HOME/.config}/opencode/commands/, commands/plannotator-review.md, commands/plannotator-annotate.md, commands/plannotator-last.md, ${PLANNOTATOR\_DATA\_DIR:-$HOME/.plannotator}/active/\<project\>/\_active-plan.md

- **Network endpoints:** https://share.plannotator.ai, https://plannotator-paste.plannotator.workers.dev, https://r.jina.ai/, https://api.github.com/repos/backnotprop/plannotator/releases/latest

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** package.json postinstall copies command files into the user's OpenCode commands directory., dist/index.js config hook enables submit\_plan and modifies OpenCode agent permissions., dist/server.js spawns a user-configurable plannotator CLI during review actions., dist/embedded.js includes optional sharing and URL-fetch features.

- **Evidence against:** No preinstall hook, obfuscated payload, eval, or shell-enabled spawn found., postinstall only copies this package's three documented command markdown files., CLI spawn uses argument arrays with shell:false and is activated by review commands., Network features are package-aligned review/share functionality; Jina key is only sent to r.jina.ai when URL annotation is invoked., No credential harvesting, secret-file reads, destructive filesystem behavior, or foreign agent-config writes found.
