Automated summary
Validates Fish scripts after editing by performing syntax and formatting checks.
Strengths
- Automates validation of .fish files to catch syntax errors early.
- Uses fish_indent to enforce consistent formatting.
- Integrates into the editing workflow for quick fixes.
Limitations
- Only works with the Fish shell.
- Does not validate plugin-managed files (e.g., _tide_).
- Requires fish and fish_indent to be installed.
Use this skill after every edit to a .fish file inside config/fish/.
Avoid using it for files from third-party plugins or non-Fish scripts.
Security analysis
SafeThe skill only runs fish syntax and formatting checks on designated .fish files, using safe commands (--no-execute and --check) and rewriting formatting. No destructive or exfiltrating actions.

How this analysis is madeExamples
Edit config/fish/functions/myfunc.fish to add a new function and then validate it.Run validation on all .fish files in config/fish/ and fix any formatting issues.I just modified config/fish/config.fish and it broke. Validate it and fix any errors.name: fish-validate description: >- Validate fish scripts after editing. Apply when writing or modifying any .fish file in config/fish/. user-invocable: false allowed-tools: Bash, Read
After editing any .fish file in config/fish/, validate it:
1. Syntax check
fish --no-execute <file>
If syntax check fails, fix the issue before proceeding.
2. Format check
Run fish_indent to verify formatting:
fish_indent --check <file>
If formatting differs, apply it:
fish_indent -w <file>
Key files to never validate
- Files inside
config/fish/functions/prefixed with_tide_(managed by the tide prompt plugin)
From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/fish-script-validation-mm8o5251/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/fish-script-validation-mm8o5251' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/fish-script-validation-mm8o5251/download' --output '.skill-downloads/fish-script-validation-mm8o5251/SKILL.md.part' && mv '.skill-downloads/fish-script-validation-mm8o5251/SKILL.md.part' '.skill-downloads/fish-script-validation-mm8o5251/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
Tools declared by the author (check availability in your agent): Bash, Read
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.
openskills syncManual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/fish-script-validation-mm8o5251/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
React Hook Form Best Practices
Development
Master React Hook Form: avoid anti-patterns, manage subscriptions, and handle reset, dirty state, and controlled inputs correctly.
Emotion to Mantine Migration
Development
Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports.
Scope Creep Detector
Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
