shell-script-reviewer

Reviews Bash, Zsh, and Fish shell scripts for bugs, security vulnerabilities, portability issues, and style violations against the Google Shell Style Guide, ShellCheck, BashPitfalls, and shell-specific idiom conventions. Use when the user asks to review, audit, lint, or improve a .sh/.bash/.zsh/.fish file, or pastes shell script content for feedback.

Quality

Content

100%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is an efficient, fully actionable reviewer workflow: it sequences dialect detection, static analysis, prioritized manual review, structured output, and escalation with concrete commands and validation feedback loops. Detail is correctly offloaded to one-level-deep reference files that all exist, keeping the overview navigable.

DimensionReasoningScore

Conciseness

The body is lean and directive (e.g. 'Treat ShellCheck's output as ground truth... don't re-derive a rule ShellCheck already flagged', 'Load only the file(s) relevant to the current script'), assumes Claude's competence, and avoids explaining basic shell concepts, so every token earns its place.

5 / 5

Actionability

Provides copy-paste-ready commands throughout (scripts/detect_shell.sh, run_shellcheck.sh, shfmt -w -i 2 -ci -bn -sr --, the diff|patch pipeline) plus a full output skeleton with before/after code blocks covering the common review cases.

5 / 5

Workflow Clarity

Steps 1-5 are explicitly sequenced with validation checkpoints: re-run static analysis to confirm after --fix, and the Step 5 escalation flagging constructs as 'needs runtime verification' with a recommended BATS test for error recovery.

5 / 5

Progressive Disclosure

A topic/file/when-to-read table plus inline citations point to six reference files and three scripts, all verified to exist, organized as one-level-deep references with the SKILL.md acting as a navigable overview.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is comprehensive, concrete, and well-triggered: it names specific review actions grounded in named authorities and provides explicit 'use when' guidance with natural synonyms and file extensions across Bash, Zsh, and Fish. It cleanly answers both what the skill does and when to invoke it with minimal conflict risk.

DimensionReasoningScore

Specificity

Lists four concrete review categories (bugs, security vulnerabilities, portability, style violations) each grounded in a named authority (Google Shell Style Guide, ShellCheck, BashPitfalls), matching the 'multiple specific concrete actions; comprehensive coverage' anchor.

5 / 5

Completeness

Explicitly states both what the skill does (reviews shell scripts for the listed issue types against named authorities) and when to use it ('Use when the user asks to review, audit, lint, or improve a .sh/.bash/.zsh/.fish file, or pastes shell script content').

5 / 5

Trigger Term Quality

Includes natural synonyms (review, audit, lint, improve) plus dialect-specific file extensions (.sh/.bash/.zsh/.fish) and a 'pastes shell script content' trigger, giving comprehensive coverage of natural terms and extensions.

5 / 5

Distinctiveness Conflict Risk

The shell-specific, three-dialect scope with explicit file extensions carves a clear niche distinct from generic code-review or lint skills, keeping conflict risk minimal.
