A.S.K. is a versioned skill library for AI agents. Define a capability once. Invoke it forever. Skills compound. Knowledge stops evaporating.
Your deploy agent re-discovers your CI config. Your notification agent re-figures-out Telegram. Your purchasing agent re-learns your spending limits. Every. Single. Session.
You've built the same capabilities ten times. They work. Then the session ends and everything evaporates. The next agent starts from scratch.
"We spent more time re-teaching agents what they already knew than building anything new."
Each skill is a versioned Markdown file with trigger conditions, input schema, methodology with reasoning, and output contract. Agents invoke skills by name. Skills compose into workflows.
Portable primitives that work anywhere. Push to GitHub, send a Telegram message, fetch a URL.
Business-specific compositions. Full deploy cycles, purchase workflows, compliance checks.
Multi-skill workflows with error propagation, retry logic, and fallback chains.
The SKILL.md file documents the why, not just the what. Future agents understand and adapt the methodology, not just execute it blindly.
# foundation/github-push/SKILL.md description: "Push changes to a GitHub repository" trigger: "When code changes need to be committed and pushed" inputs: repo: string # Target repository branch: string # Target branch message: string # Commit message methodology: # 1. Stage changes (why: prevents committing unintended files) # 2. Validate diff (why: catches accidental secret exposure) # 3. Commit with conventional message format # 4. Push with force-with-lease (why: prevents overwriting remote changes) outputs: commit_sha: string push_status: success | conflict | error

A.S.K. is MIT licensed. The Quick-Start Bundle is for teams who want the structured walkthrough, production patterns, and Python runtime instead of building from the spec.
