script-writer

Write production-ready one-off scripts and automation utilities with proper error handling and safety patterns. Use when developing bash automation, Python CLI tools, shell scripts, system administration scripts, or command-line batch processing—e.g., "write a script to process files", "python one-liner for data conversion", "bash automation for backups", "shell script with error handling".

Discovery

92%

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

This is a strong skill description that clearly articulates capabilities and provides explicit trigger guidance with concrete examples. The description uses proper third-person voice and includes natural user phrases. Minor weakness is potential overlap with general coding or Python-specific skills, though the focus on automation and one-off scripts provides reasonable differentiation.

DimensionReasoningScore

Specificity

Lists multiple concrete actions: 'production-ready one-off scripts', 'automation utilities', 'proper error handling and safety patterns'. Specifies domains like bash automation, Python CLI tools, shell scripts, system administration scripts, and batch processing.

3 / 3

Completeness

Clearly answers both what ('Write production-ready one-off scripts and automation utilities with proper error handling') AND when ('Use when developing bash automation, Python CLI tools...') with explicit trigger examples like 'write a script to process files'.

3 / 3

Trigger Term Quality

Excellent coverage of natural terms users would say: 'bash automation', 'Python CLI tools', 'shell scripts', 'process files', 'python one-liner', 'data conversion', 'backups', 'error handling'. These are phrases users naturally use when requesting scripting help.

3 / 3

Distinctiveness Conflict Risk

While it specifies scripting and automation, there's potential overlap with general coding skills or Python development skills. The focus on 'one-off scripts' and 'automation utilities' helps distinguish it, but 'Python CLI tools' could conflict with broader Python skills.

Implementation

72%

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

This skill content is well-structured and concise, establishing clear safety principles and quality standards without over-explaining. The main weakness is the lack of concrete, executable code examples in the main file—all implementation details are deferred to references. Adding at least one minimal example pattern would improve actionability.

Suggestions

Add a minimal executable code example (e.g., a basic error-handling pattern in bash or python) to demonstrate the safety principles in practice

Include a brief validation workflow for script development: write -> test -> verify error handling -> deliver

DimensionReasoningScore

Conciseness

The content is lean and efficient, avoiding explanations of concepts Claude already knows. Every section serves a purpose with no padding or unnecessary context about what scripts are or how they work.

3 / 3

Actionability

Provides clear principles and requirements but lacks concrete code examples. The guidance is specific (error handling, exit codes, logging patterns) but no executable snippets are included in the main skill file—these are deferred to references.

2 / 3

Workflow Clarity

The output requirements section provides a 3-step checklist, but there's no explicit validation workflow or feedback loop for script development. For a skill involving potentially destructive operations, explicit validation steps would strengthen this.

2 / 3

Progressive Disclosure

Excellent structure with clear overview content and well-signaled one-level-deep references to bash-scripts.md and python-scripts.md. The instruction to load references 'on demand' based on language is appropriately organized.
