## For AI agents

Every page supports content negotiation on its human URL:
- JSON API: append `?format=json` or send `Accept: application/json`
- JSON-LD: append `?format=ldjson` or send `Accept: application/ld+json`
- Markdown: append `?format=md` or send `Accept: text/markdown`
- Per-page API: https://pr-1-7cfcfe393d12.thally.app/api/docs/{page-id}
- Search API: https://pr-1-7cfcfe393d12.thally.app/api/search?q={query}
- Capability manifest (skill): https://pr-1-7cfcfe393d12.thally.app/skill.md
- Agent guidance (editing these docs): https://pr-1-7cfcfe393d12.thally.app/AGENTS.md
- MCP server (attach docs as native tools): https://pr-1-7cfcfe393d12.thally.app/api/mcp
- Agent readiness: https://pr-1-7cfcfe393d12.thally.app/api/agent-readiness

### Recommended workflow

1. Use this index, the search API, or `search_docs` before choosing a page.
2. Read the smallest set of relevant pages and follow their prerequisite links.
3. Treat the published docs as the source of truth. Label inferences and say when evidence is missing.
4. Cite the canonical human page URLs, not only API endpoints.
5. Use `/AGENTS.md` before editing a repository. The public MCP server is read-only.

## Get Started

### Get Started

- [Seamline Toolkit](https://pr-1-7cfcfe393d12.thally.app/): Ship API and configuration contracts with confidence using Specdiff and Envlock.
- [Quickstart](https://pr-1-7cfcfe393d12.thally.app/quickstart): Install Specdiff and Envlock, run your first comparison and validation, and verify the results.

## Specdiff

### Overview

- [Specdiff Overview](https://pr-1-7cfcfe393d12.thally.app/specdiff-overview): Breaking-change detection for JSON Schema and OpenAPI documents.

### Reference

- [@specdiff/core API](https://pr-1-7cfcfe393d12.thally.app/specdiff-core-api): Complete API reference for every public export in @specdiff/core v0.1.0.
- [@specdiff/cli Reference](https://pr-1-7cfcfe393d12.thally.app/specdiff-cli): Command-line reference for the specdiff CLI — compare documents, list rules, and gate CI pipelines.

## Envlock

### Overview

- [Envlock Overview](https://pr-1-7cfcfe393d12.thally.app/envlock-overview): Declare the environment variables your app needs once, then validate, type-infer, document, diff, and redact them everywhere.

### Reference
