The canonical Claude ecosystem reference
Auto-synced official docs and curated Anthropic team insights, built for deterministic local lookup via the Claude Code CLI — no RAG, no retrieval blind spots.
Auto-updated mirror of the official Claude documentation, refreshed every 12h via GitHub Actions. Structure follows Claude Project Knowledge Base best practices.
Folders mirror the official upstream sitemap sections 1:1, so navigation matches platform.claude.com and code.claude.com.

There are two ways to consume this knowledge base. They are not equivalent — pick based on the precision you need.
git clone https://github.com/coroboros/archivist.git
cd archivist
claudeClaude Code reads files directly with Grep (full-text, deterministic) and Read (full file content). Every fact in the docs is reachable; no fact is silently dropped. Cross-references resolve dynamically because Claude can follow links across the entire mirror in one session.
This is the right path when you need surgical accuracy — writing technical docs, reviewing implementation choices against current Anthropic guidance, refining skills, cross-referencing API ↔ Code ↔ Platform guides.
Use docs/INDEX.md for cross-section topic navigation, then Grep/Read from there.
This repo ships claude/skills/ask-archivist/SKILL.md, a companion skill that wraps the deterministic lookup workflow (INDEX Grep → section Grep → full-file Read → cite). Install it once, then ask questions in natural language — the skill auto-detects the mirror and cites the files it reads.
# From an archivist clone
mkdir -p ~/.claude/skills/ask-archivist
cp claude/skills/ask-archivist/SKILL.md ~/.claude/skills/ask-archivist/
# Point the skill at any mirror location (optional — defaults to $HOME/archivist or the current repo)
export ARCHIVIST_PATH="$PWD"Why this over the built-in claude-code-guide subagent? Both answer the same kinds of questions, but on opposite ends of the precision/freshness tradeoff:
ask-archivist |
claude-code-guide (built-in) |
|
|---|---|---|
| Source | Local mirror — every line reachable | Live docs.claude.com via WebFetch / WebSearch |
| Method | Grep + full-file Read |
Relevance-ranked web fetch |
| Determinism | Reproducible, no silent miss | Depends on what search ranks — same RAG-style failure mode as Claude Projects |
| Cross-refs | Resolves across the whole mirror in one session | One fetch per follow-up |
| Freshness | 12h refresh ceiling | Real-time |
Use ask-archivist by default for precision work. Fall back to claude-code-guide when the change is < 12h old or the question is about runtime behavior / community patterns the docs don't cover — the skill explicitly names this escape-hatch so you keep the user in control.
1. Create a Claude Project
2. Connect this repo as a GitHub data source (or upload docs/ folders)
3. Use the system prompt at claude/archivist-project/system-prompt.xml
Convenient for non-technical users or away-from-terminal queries — but understand the tradeoff before relying on it for precise work:
- Claude Projects use RAG (retrieval-augmented generation) once content exceeds the context window: docs are chunked, embedded, and retrieved by semantic similarity to your query.
- RAG is probabilistic: the relevant chunk may not surface in the top-k results, especially when your query phrasing differs from the doc's wording. Misses are silent — the model fills gaps with training-data approximations.
- Concrete example: asked about Claude Code worktrees, Claude Desktop has been observed to suggest manual
git worktreesetup, missing the nativeclaude --worktreeflag — even though it appears in 27 files of this mirror.
Full pedagogical write-up: claude/archivist-project/README.md.
For high-precision work (regulated content, technical writing, audit-grade research), use the CLI path above.
The GitHub Actions workflow runs every 12h:
- Fetches latest Claude docs from Anthropic sitemaps
- Generates markdown files with YAML frontmatter
- Rebuilds README indexes and the cross-section
docs/INDEX.md - Auto-commits, tags, creates GitHub releases
Scripts run on Bun. To update docs locally: pnpm update (requires bun and pnpm).
Safety guard: Aborts if > 25% of files in any docs folder are deleted.
| Variable | Type | Purpose |

variable | Max % of deleted files before abort (default: 25) |
