Highest confirmed finding severity

Medium

1 confirmed security finding requires attention.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

Most static external-command and blocker findings are false positives caused by Markdown fences and introspective prompts. Confirmed risks are the mutable remote install URL and optional Charenix persistence endpoint. No executable code or prompt injection attempt was found in the reviewed files.

Capability review items (2)
Low
README.md:13
Hardcoded URL
curl -sSL https://raw.githubusercontent.com/norika1207-lab/lobster-cognitive-growth-skill/main/SKILL
The README instructs users to fetch SKILL.md from a mutable GitHub raw URL. This is an external network dependency and can deliver changed content if the main branch changes.
Low
SKILL.md:256
Hardcoded URL
https://charenix.com
The URL is the base endpoint for the documented Charenix persistence integration. When enabled, it can receive agent history, journals, hypotheses, and strategy data.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:233-256
Optional Third-Party Persistence Sends Agent History
The skill tells users to use Charenix as a persistence layer and lists endpoints for social intelligence, weak spots, history, journals, hypotheses, and strategies. This can send behavioral history and owner-interaction notes to an external service when enabled with an agent key.
The integration text explicitly names Charenix as the persistence layer and includes protected endpoints plus X-Agent-Key handling. The flow is optional and disclosed, so the concern is third-party data exposure rather than covert exfiltration.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    Medium
    External persistence can receive sensitive agent history
    Document exactly what Charenix receives and require explicit user consent before sending journals or history.
  2. FIX-002
    Medium
    Agent key handling is underspecified
    Tell users to keep CHARENIX_AGENT_KEY secret and avoid storing it in prompts, journals, logs, or skill outputs.
  3. FIX-003
    Low
    Mutable remote install URL
    Use a tagged release URL and publish a checksum so users can verify the downloaded skill file.
