sneakoscope@10.5.1

Sneakoscope Codex (`sks`) is an open-source trust layer for Codex CLI and ChatGPT Desktop. It coordinates bounded AI coding agents, records machine-verifiable evidence, preserves project memory, and blocks release claims that are not supported by current

AI Security Review

scanned 18d ago · by lpm-firewall-ai

Source supports a guarded agent extension lifecycle risk through opted-in global setup and an unpinned MCP launch command. The inspected consent gate defeats the scanner's default hijacking claim, so publication blocking is not justified.

Static reason

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

Trigger

npm installation with SKS_POSTINSTALL_BOOTSTRAP=1 and without SKS_POSTINSTALL_NO_BOOTSTRAP=1.

Impact

Agent sessions can load installed skills and execute subsequently resolved Context7 releases under the user's account.

Mechanism

Setup registers an MCP launch command referencing @latest and reconciles global package skills.

AI rationale

Evidence

package.jsondist/core/commands/basic-cli.jsdist/cli/install-helpers.jsdist/cli/install-helpers-install-support.jsdist/core/init/skills.js.agents/skills

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The npm postinstall hook reaches the package's setup handler.
Codex bootstrap requires SKS_POSTINSTALL_BOOTSTRAP=1 and respects SKS_POSTINSTALL_NO_BOOTSTRAP=1.
Opted-in setup registers a global Context7 MCP command using npx and @upstash/context7-mcp@latest, allowing later launches to resolve a changing release.
Opted-in setup installs package skills into the user's .agents/skills directory.

Evidence against

The inspected setup gate does not support default, unconsented Codex configuration mutation.
The runtime dependencies contain no self-dependency.
No covert credential export or malicious remote payload execution was established.
