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 found many command-like patterns, but most SKILL.md hits are Markdown documentation examples or formatting syntax. One confirmed issue remains: scripts/autocorrect.ts builds a shell command with a user-controlled file path, creating command injection risk. No prompt injection, network exfiltration, environment access, or malicious intent was found.

Capability review items (3)
High
scripts/autocorrect.ts:1-5scripts/main.ts:155-156
Shell Command Injection Through File Path
scripts/autocorrect.ts imports child_process and passes a template string to execSync. The file path comes from the CLI argument flow in scripts/main.ts, so a crafted path containing quotes or shell metacharacters can break out of the quoted argument and run arbitrary shell commands.
The code directly interpolates a user-supplied file path into an execSync shell command. Quoting the path does not prevent injection when the value can contain quote characters.
Medium
SKILL.md:212-214scripts/autocorrect.ts:5
Unpinned External Tool Execution
The workflow instructs users to run npx with bun and the script invokes npx autocorrect-node. This executes external tooling without a pinned package version in the documented command path, creating supply-chain and reproducibility risk.
The external execution path is explicit and repeatable. The finding is not evidence of malware, but unpinned npx execution is a real marketplace risk.
Medium
scripts/main.ts:102-108SKILL.md:99-101
In-Place File Modification
scripts/main.ts reads and writes the target file directly, and the skill also offers a typography-only mode that modifies the original file. This is expected formatter behavior, but it can overwrite user content if the wrong path is supplied or backup handling is bypassed.
The file read and write behavior is clear in the implementation and documentation. It is legitimate for a formatter, but it has user-data impact.

Risk findings

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

Confirmed security concerns (2)

RISK-001 Low
scripts/quotes.ts:1-4
Benign Unicode Escape Use
scripts/quotes.ts uses Unicode escapes for typographic quotation marks. This is not obfuscation and matches the documented quote replacement feature.
The escape sequences are immediately used as replacement quote characters. There is no hidden control flow, decoding layer, or suspicious payload.
RISK-002 Low
SKILL.md:22-37
Hidden Configuration File Access
The skill checks project and home EXTEND.md paths under .baoyu-skills for optional preferences. This is a bounded configuration lookup, but users should know it may read formatter preferences from hidden directories.
The documented paths are narrow and preference-oriented, so this is not secret harvesting. It is still a hidden-file access pattern worth disclosing.

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)

SKILL.md:3SKILL.md:66-71SKILL.md:218-226
Static Analyzer False Positives in Markdown Text
Most SKILL.md external command findings are Markdown examples, inline code, tables, and fenced commands that document formatter usage. The weak cryptography and reconnaissance alerts did not correspond to cryptographic operations or system probing in the reviewed file.
Line-number review shows documentation content and Markdown syntax, not executable code for cryptography or reconnaissance. The safe interpretation is supported by the surrounding workflow text.
