akm-opencode@0.10.261017
OpenCode plugin for AKM with discovery tools, feedback, memory, and automatic learning proposals from corrections and recurring workflows.
AI Security Review
scanned 6d ago · by lpm-firewall-aiBy default, session-idle hooks send session-derived prompts through the user’s configured OpenCode model runner, potentially spending their provider tokens without a per-run request. The feature is disclosed and can be disabled, but an opt-out default does not satisfy the automatic-spending rule.
Static reason
No blocking static signals were detected.
Trigger
OpenCode emits `session.idle`; extraction is enabled by default and runs at most once per configured interval for each session.
Impact
When the configured provider charges for model use, session content is processed and tokens may be spent without a per-extraction user request; extracted insights are queued as proposals.
Mechanism
The plugin invokes `akm proposal extract` for the session. AKM builds a prompt from session events and runs model work through `opencode run`, using the user’s OpenCode configuration and login.
Attack narrative
On idle events, the plugin automatically starts AKM session extraction unless disabled. AKM builds a prompt from session data and runs model work through the user’s configured OpenCode account. This can consume paid provider tokens without a per-run request; the resulting insights are queued as proposals. The README discloses the feature and opt-out, but the review rules treat an opt-out default as insufficient consent for automatic spending.
AI rationale
By default, session-idle hooks send session-derived prompts through the user’s configured OpenCode model runner, potentially spending their provider tokens without a per-run request. The feature is disclosed and can be disabled, but an opt-out default does not satisfy the automatic-spending rule.

Decision evidence
public snapshotAI called this Malicious at 87.0% confidence as Malware with low false-positive risk.
Evidence for block
- Automatic memory extraction is enabled unless `AKM_AUTO_MEMORY=0`; the plugin triggers it on `session.idle`.
- The extraction command reads session events, builds a prompt, and invokes session extraction to queue proposals.
- AKM’s OpenCode model runner calls `opencode run` using the user’s OpenCode configuration and login, so extraction can consume the configured provider’s tokens.
- The README says idle events fire after every turn and describes the extraction opt-out.
Evidence against
- The feature is part of the package’s stated automatic learning and memory workflow.
- The README documents the behavior and provides an opt-out.
- The package manifest has no install lifecycle hook; its scripts are for building and typechecking.
