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

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.

Static analysis reported many command-execution alerts, but review shows they are Markdown code fences and example profiler commands, not executable skill code. The skill is documentation-only, with low residual risk from copied examples that run local profilers, open local files, or call httpbin.org for I/O benchmarking.

Capability review items (3)
Low
SKILL.md:200-213
Example Commands Profile Local Processes
The py-spy examples inspect a local process by PID and can expose stack information if a user runs them against sensitive production services. This is legitimate performance tooling, and no evidence shows the skill executes these commands automatically.
The line-numbered context shows explicit py-spy commands against a PID. The risk depends on a user manually running the documented command, so severity remains low.
Low
SKILL.md:560-589
Example HTTP Benchmark Uses External Service
The async I/O example imports requests and aiohttp and calls https://httpbin.org/delay/1. This is a benign timing demonstration, but copied code would make outbound network requests.
The URLs and HTTP client calls are visible in the referenced lines. They target a public test endpoint and do not include credentials or exfiltration logic.
Low
SKILL.md:666SKILL.md:730-739
Examples Open Local Files and Databases
The SQLite and iterator examples open example.db or a caller-provided filename. This is normal optimization guidance, but users should test with non-sensitive data.
The examples clearly demonstrate local file and database access. They are not hidden behavior because SKILL.md is the only file and contains documentation examples only.

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.

Static false positives ignored (1)
Low
SKILL.md:47-69SKILL.md:75-125SKILL.md:782-822
Static Command Alerts Are Markdown False Positives
The many Ruby or shell backtick findings correspond to Markdown fenced code blocks and sample snippets. No standalone script, installer, or automatic command runner was found in the skill package.
Line-numbered review shows fenced code examples rather than executable Ruby backticks. The package contains only SKILL.md, so there is no execution surface outside user-copied examples.

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