Anto01 9c91d778d9 feat: Claude Code context injection (UserPromptSubmit hook)
Closes the asymmetry the user surfaced: before this, Claude Code
captured every turn (Stop hook) but retrieval only happened when
Claude chose to call atocore_context (opt-in MCP tool). OpenClaw had
both sides covered after 7I; Claude Code did not.

Now symmetric. Every Claude Code prompt is auto-sent to
/context/build and the returned pack is prepended via
hookSpecificOutput.additionalContext — same as what OpenClaw's
before_agent_start hook now does.

- deploy/hooks/inject_context.py — UserPromptSubmit hook. Fail-open
  (always exit 0). Skips short/XML prompts. 5s timeout. Project
  inference mirrors capture_stop.py cwd→slug table. Kill switch:
  ATOCORE_CONTEXT_DISABLED=1.
- ~/.claude/settings.json registered the hook (local config, not
  committed; copy-paste snippet in docs/capture-surfaces.md).
- Removed /wiki/capture from topnav. Endpoint still exists but the
  page is now labeled "fallback only" with a warning banner. The
  sanctioned surfaces are Claude Code + OpenClaw; manual paste is
  explicitly not the design.
- docs/capture-surfaces.md — scope statement: two surfaces, nothing
  else. Anthropic API polling explicitly prohibited.

Tests: +8 for inject_context.py (exit 0 on all failure modes, kill
switch, short prompt filter, XML filter, bad stdin, mock-server
success shape, project inference from cwd). Updated 2 wiki tests
for the topnav change. 450 → 459.

Verified live with real AtoCore: injected 2979 chars of atocore
project context on a cwd-matched prompt.

AtoCore

Personal context engine that enriches LLM interactions with durable memory, structured context, and project knowledge.

Quick Start

pip install -e .
uvicorn src.atocore.main:app --port 8100

Usage

# Ingest markdown files
curl -X POST http://localhost:8100/ingest \
  -H "Content-Type: application/json" \
  -d '{"path": "/path/to/notes"}'

# Build enriched context for a prompt
curl -X POST http://localhost:8100/context/build \
  -H "Content-Type: application/json" \
  -d '{"prompt": "What is the project status?", "project": "myproject"}'

# CLI ingestion
python scripts/ingest_folder.py --path /path/to/notes

# Live operator client
python scripts/atocore_client.py health
python scripts/atocore_client.py audit-query "gigabit" 5

API Endpoints

Method Path Description
POST /ingest Ingest markdown file or folder
POST /query Retrieve relevant chunks
POST /context/build Build full context pack
GET /health Health check
GET /debug/context Inspect last context pack

Architecture

FastAPI (port 8100)
  |- Ingestion: markdown -> parse -> chunk -> embed -> store
  |- Retrieval: query -> embed -> vector search -> rank
  |- Context Builder: retrieve -> boost -> budget -> format
  |- SQLite (documents, chunks, memories, projects, interactions)
  '- ChromaDB (vector embeddings)

Configuration

Set via environment variables (prefix ATOCORE_):

Variable Default Description
ATOCORE_DEBUG false Enable debug logging
ATOCORE_PORT 8100 Server port
ATOCORE_CHUNK_MAX_SIZE 800 Max chunk size (chars)
ATOCORE_CONTEXT_BUDGET 3000 Context pack budget (chars)
ATOCORE_EMBEDDING_MODEL paraphrase-multilingual-MiniLM-L12-v2 Embedding model

Testing

pip install -e ".[dev]"
pytest

Operations

  • scripts/atocore_client.py provides a live API client for project refresh, project-state inspection, and retrieval-quality audits.
  • docs/operations.md captures the current operational priority order: retrieval quality, Wave 2 trusted-operational ingestion, AtoDrive scoping, and restore validation.
