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. LPM treats this as warn-only first-party agent extension lifecycle risk. Install automatically registers this package as an OpenCode TUI plugin by writing the user's OpenCode cli.json plugins list and copying plugin files into the OpenCode config directory. The usage client later reads the local OpenCode Go key and calls the official usage API. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-27T19:57:53.208Z - **Finished:** 2026-09-27T19:58:44.985Z - **Download time:** 758 ms - **Static scan time:** 44 ms - **AI review time:** 50974 ms - **Total time:** 51777 ms The recorded confidence comes from the underlying analysis.

The usage client later reads the local OpenCode Go key and calls the official usage API. - **Trigger:** npm postinstall, or running the opencode-usage-bar bin, executes scripts/install.mjs. - **Impact:** OpenCode loads this third-party plugin after install without a separate consent step. The plugin can read the local OpenCode Go credential and query subscription usage at the official endpoint. - **Evidence paths:** package.json, scripts/install.mjs, dist/usage.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-27T19:58:44.985Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script copies dist into the OpenCode config usage-bar directory and writes or updates the plugins array in cli.json so OpenCode loads that path. A legacy tui.json entry is rewritten only when it already refers to usage-bar. - **Rationale:** Postinstall is first-party setup of this package's own OpenCode plugin: it copies its files and adds its path to OpenCode cli.json rather than hijacking a foreign agent surface or exfiltrating secrets. The usage key is forwarded only to the fixed official OpenCode Go usage URL, so the install-time control-surface write is a warning, not a publish block. - **Files touched:** ~/.config/opencode/cli.json, ~/.config/opencode/usage-bar, ~/.config/opencode/tui.json, ~/.local/share/opencode/opencode.db, ~/.local/share/opencode/auth.json - **Network endpoints:** https://opencode.ai/zen/go/v1/usage ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** npm postinstall unconditionally runs scripts/install.mjs., That script copies this package's dist into the OpenCode config directory under usage-bar., It then rewrites the user OpenCode cli.json plugins list, appending this install path or replacing an existing usage-bar spec, and sets the cli.json schema if missing., Runtime usage lookup sends the OpenCode Go API key only to the fixed official usage URL. - **Evidence against:** Plugin list updates match specs containing usage-bar or append only this package's install directory; other plugin entries are left in place., The API key is read from OPENCODE\_GO\_API\_KEY, the local opencode sqlite credential store, or auth.json and is sent as a Bearer token only to https://opencode.ai/zen/go/v1/usage., No child process, eval, obfuscation, or self-dependency install chain is present. ## Affected versions and remediation This report applies to @leo.gimp/opencode-usage-bar@2.0.1. - Review the evidence and your use of @leo.gimp/opencode-usage-bar@2.0.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
