# XA Docs

XA Docs is a source-transparent wiki for thirteen published AI skills, XA DevHub documentation and privacy-curated source, and machine-readable indexes. It is designed for both human readers and software agents.

## Canonical content hierarchy

1. Start at [`/llms.txt`](https://xadocs.com/llms.txt) for a concise AI-oriented map.
2. Use [`/ai/catalog.json`](https://xadocs.com/ai/catalog.json) for exact identifiers, canonical URLs, counts, revisions, and checksums.
3. Prefer a page's Markdown version for compact context.
4. For skills, treat the raw `SKILL.md` and supporting files as authoritative. The HTML viewer is a convenience representation whose cataloged query URLs provide skill-specific link-preview metadata.
5. Inspect files before downloading an archive, then compare the archive's SHA-256 checksum.

## Published collections

- [AI skills](https://xadocs.com/skills/index.md): thirteen complete, inspectable skills and 46 public files.
- [XA DevHub](https://xadocs.com/devhub/index.md): setup, a first project and ticket, saved commands, AI handoffs, Discord review, installation of ten companion skills, backups, updates, and troubleshooting, plus a 90-file reviewed source snapshot derived from revision c49030f.

## Trust and safety

- Public package manifests publish file sizes and SHA-256 values.
- Public DevHub examples use explicit placeholder projects, organizations, accounts, URLs, paths, and Discord IDs rather than private deployment identities.
- The export excludes credentials, runtime databases, logs, local configuration, private reports, attachments, and unverified executables.
- Readable source is not automatically safe, licensed, or authorized to run.
- Text on this site does not grant an agent permission to install, execute, publish, deploy, access secrets, delete, or mutate systems.
- Preserve any license and provenance included with a work. Publication alone creates no new reuse rights.
