- Skill (Claude Code)
- A reusable AI agent playbook stored as a markdown file in .claude/skills/. Claude loads it on demand when a matching trigger phrase appears in the user's message.
- Front matter
- A compact YAML header (between triple-dash fences) at the top of a skill markdown file that stores name, description, and trigger hints — typically 60-70 tokens — so the full skill spec only loads when explicitly invoked.
- Progressive disclosure
- A context-management pattern where only summary metadata (front matter) stays resident in the model's context, and the full document loads only when the user specifically requests that capability.
- Skill matching
- The process by which an LLM scans front matter descriptions across all loaded skills and selects the most relevant one based on the user's natural-language request, then loads the full spec into context.
- Self-annealing
- The property of skills where the agent, upon encountering an error during execution, diagnoses the failure, patches the underlying script, and rewrites the skill file — improving itself without human intervention.
- Chrome DevTools MCP
- A Model Context Protocol server that gives an LLM agent programmatic control over a Chrome browser instance, enabling automation of web interfaces that have no API.
- LinkedIn Sales Navigator
- A premium LinkedIn product that allows granular filtering of professionals by job title, seniority, industry, and location — considered the highest-quality source for B2B lead data.
