Agent Skills Open Standard
The Agent Skills format is an open standard for extending AI agent capabilities with specialized knowledge and workflows. Originally developed by Anthropic, adopted by 25+ agent products.
Source: https://agentskills.io
When to use this skill: Before creating any skill that should be portable across multiple agent products. For Claude Code-specific features (hooks, context fork, model selection, invocation control), see ../claude-skills-overview-2026/SKILL.md instead.
SKILL.md Format
Every skill is a directory containing a SKILL.md file with YAML frontmatter and Markdown body:
skill-name/
├── SKILL.md # Required: metadata + instructions
├── scripts/ # Optional: executable code
├── references/ # Optional: documentation loaded on demand

perl-lint
This skill should be used when the user asks to lint Perl code, run perlcritic, check Perl style, format Perl code, run perltidy, or mentions Perl Critic policies, code formatting, or style checking.
28brainstorming-skill
You MUST use this before any creative work - creating features, building components, adding functionality, modifying behavior, or when users request help with ideation, marketing, and strategic planning. Explores user intent, requirements, and design before implementation using 30+ research-validated prompt patterns.
18add-doc-updater
Add automated documentation updater to any Claude skill. Creates a Python sync script that downloads upstream docs, processes markdown for AI consumption, and maintains local cache with configurable refresh. Collects template variables, then delegates implementation through 5-phase workflow. Use when adding auto-updating reference documentation to plugins or skills.
11work-backlog-item
Use when working, planning, or closing a backlog item. Bridges backlog items to SAM planning with GitHub Issue/Project/Milestone tracking. No args: interactive browser. '#N': load from GitHub Issue #N. Title substring: auto-grooming, RT-ICA gate, GitHub sync, SAM planning. '--auto {title}': autonomous mode — no AskUserQuestion, derives data from research files, logs decisions. 'close {title}': dismiss without completion — reason required (duplicate, out_of_scope, superseded, wontfix, blocked). ADR-9. 'resolve {title}': mark DONE with evidence trail — summary required. ADR-9. 'setup-github': init labels, project, milestone. '--language' and '--stack' select Layer 1/2 profile. STOPS if item has Plan field or RT-ICA returns BLOCKED.
11agent-browser
Browser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction.
11python3-review
Comprehensive Python code review checking patterns, types, security, and performance. Use when reviewing Python code for quality issues, when auditing code before merge, or when assessing technical debt in a Python codebase.
