osborn@0.9.240

Voice AI coding assistant - local agent that connects to Osborn frontend

AI Security Review

scanned 25d ago · by lpm-firewall-ai

osborn 0.9.240 is a user-started voice coding agent with no registry lifecycle hook. Local Claude credential checks and settings use are part of that product and are not an install-time control-surface hijack.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

User invocation of the osborn or osborn-recall binaries, not npm install.

Impact

No unconsented install mutation, hidden credential export, or remote payload execution was found.

Mechanism

The process reads local Claude credentials and session files, may merge two compaction settings, and during an interactive login forwards the newly issued token to the connected frontend callback.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 84.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json exposes osborn and osborn-recall bins and only dev, build, and prepublishOnly scripts, with no preinstall, install, or postinstall hook and no dependency on osborn itself.
dist/claude-auth.js points CREDENTIALS_PATH at the local ~/.claude/.credentials.json file and uses it to decide whether a Claude login already exists.
The flagged region in dist/claude-llm.js is a commented-out loader for ~/.claude/skills, not an install-time writer or network call.
getClaudeProjectsDir returns the local ~/.claude/projects directory for session lookup.
loadSkillsList only reads SKILL.md files under the agent directory .claude/skills when the user starts the agent.
getOsbDir places summary files beside Claude session data under CLAUDE_CONFIG_DIR or ~/.claude.
osborn-recall spawns the local recall CLI with inherited stdio and does not install another package.
getSessionPaths only computes local Claude project, conversation, and subagent paths.

Evidence against

Importing the agent module merges autoCompactWindow and cleanupPeriodDays into ~/.claude/settings.json after the user starts the CLI.
After the user completes Claude login, the new OAuth token is sent to the already connected frontend callback so that frontend can persist it.
