Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

Installation context

Check the current Skill page

This page summarizes report evidence only. The Skill page provides the canonical install advisory.

Open current Skill page

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

Most static findings are false positives caused by Markdown links, code fences, placeholders, and ordinary marketing terms. Three findings confirm one underlying behavior: the skill uses shell substitution and invokes a repository-local Python scoring script.

Report position

Latest published report

Latest refers to the report sequence, not to artifact currentness.

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

  1. Source

    Commit and path bound

  2. Artifact

    Content and tree hashes bound

Capability review items (3)
Medium
Ruby/shell backtick execution
Declare goal, profile `roi-<goal>`, `scope: roi`, `assessment_time: forecast|actual`, campaign `roll
The line explicitly resolves a repository root with shell substitution and invokes a local Python scoring script. The Git-root fallback may select project-controlled executable code.
Medium
Ruby/shell backtick execution
For CVI, combine complete typed ACE results from [fit-scorer](../../discover/fit-scorer/SKILL.md), c
Although Markdown backticks delimit the text, the content directs the agent to run python3 against a resolved local script. This is intentional external command execution.
Medium
Shell command substitution
Declare goal, profile `roi-<goal>`, `scope: roi`, `assessment_time: forecast|actual`, campaign `roll
The AARON_SKILLS_ROOT assignment contains explicit $(git rev-parse ...) shell command substitution. It runs Git and then uses the resulting path for local script execution.

Risk findings

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

No confirmed security findings were recorded for this completed audit.

Remediation

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

  1. FIX-001
    Medium
    The repository-root fallback can select scripts from the current project instead of a trusted skill installation.
    Require a validated plugin root and stop when it is unavailable instead of falling back to the current Git repository.
  2. FIX-002
    Medium
    The optional C3 workflow invokes a local Python scorer.
    Request execution approval, verify the resolved script is inside the trusted installation, and pass validated file arguments without shell interpolation.

Analysis metadata

Audit model: codex

Analysis state: Complete

Scope is limited to the recorded files, lines, methods, and evidence. No runtime or sandbox execution is claimed.

Verify and export

The manifest and lockfile bind install artifacts to cryptographic hashes. This integrity claim is separate from the security assessment.
