Our review

Ingests project documentation and code into a persistent semantic memory using Voyage embeddings and Qdrant vector database for cross-session retrieval.

Strengths

  • Persistent memory across sessions
  • Dual indexing (semantic + temporal)
  • Intelligent chunking with overlap
  • High recall accuracy (Recall@10 >0.98)

Limitations

  • Requires Qdrant running locally
  • Requires Voyage API key
  • Only supports specific file types
  • Memory usage of 1.4GB RAM per 1M vectors
When to use it

When you need to retain context across sessions or search large project knowledge efficiently.

When not to use it

When the project is small and session context suffices, or you cannot set up Qdrant and an API key.

Security analysis

Safe
Quality score90/100

The skill runs local bun commands (ingest/search) on a predefined project, no destructive actions, no external data exfiltration, and no obfuscated payloads. The setup requires a local Qdrant instance and API key, but these are not transmitted elsewhere. The commands only interact with local file system and local Qdrant, posing no security risk.

No concerns found

Examples

Remember architecture decisions
Ingest the architecture docs from the project into Atlas so I can query them later. Use the atlas ingest command on the docs/ folder.
Search previous database schema discussions
Search Atlas memory for all mentions of 'database schema' with a limit of 10 results.
Store a meeting note
Remember this decision: we will use PostgreSQL with Prisma as the ORM. Store it in Atlas for future reference.

name: atlas description: Ingest project documentation and code into persistent semantic memory (Qdrant + Voyage embeddings). Use when user wants to remember context across sessions, ingest docs, or search previous work. Requires Qdrant running locally and VOYAGE_API_KEY set. allowed-tools: Bash(bun:*)

Atlas - Persistent Semantic Memory

Atlas provides automatic context ingestion and retrieval using Voyage embeddings + Qdrant vector database. Solves the context overflow problem by storing knowledge persistently across sessions.

Quick Start

Prerequisites

  1. Qdrant running locally:
docker run -d -p 6333:6333 qdrant/qdrant
  1. VOYAGE_API_KEY set (get from https://voyageai.com):
export VOYAGE_API_KEY="your-key-here"
  1. Verify setup:
curl http://localhost:6333/health

Ingesting Context

Store files in Atlas memory for persistent retrieval:

Ingest Single File

cd ~/production/atlas
bun run --filter @inherent.design/atlas atlas ingest /path/to/file.md

Ingest Directory (Recursive)

cd ~/production/atlas
bun run --filter @inherent.design/atlas atlas ingest /path/to/docs/ --recursive

Ingest Multiple Paths

cd ~/production/atlas
bun run --filter @inherent.design/atlas atlas ingest README.md src/index.ts docs/ -r

What gets ingested:

  • Supported: .md, .ts, .tsx, .js, .jsx, .json, .yaml, .qntm, .rs, .go, .py, .sh, .css, .html
  • Ignored: node_modules, .git, dist, build, coverage, .atlas

Processing:

  • Chunks text (768 tokens, 13% overlap) for semantic coherence
  • Embeds with Voyage-3-large (1024-dim)
  • Stores in Qdrant with dual-indexing (semantic QNTM keys + temporal timestamps)
  • Preserves original text for future consolidation

Searching Context

Retrieve relevant context semantically:

Basic Search

cd ~/production/atlas
bun run --filter @inherent.design/atlas atlas search "typescript patterns"

Limited Results

cd ~/production/atlas
bun run --filter @inherent.design/atlas atlas search "memory consolidation" --limit 10

Temporal Filtering (Since Date)

cd ~/production/atlas
bun run --filter @inherent.design/atlas atlas search "sleep patterns" --since "2025-12-25"

Chronological Timeline

cd ~/production/atlas
bun run --filter @inherent.design/atlas atlas timeline --since "2025-12-01"

When to Use This Skill

Use Atlas when:

  • User asks to "remember this across sessions"
  • Project context is too large for single session
  • User wants to search previous work/decisions
  • Documentation needs to be queryable
  • Building on previous research or code

Examples:

  • "Remember the API architecture we discussed"
  • "What did we decide about the database schema?"
  • "Find all mentions of authentication patterns"
  • "Ingest all the .atlas research files"

Architecture

Built on .atlas research (Steps 1-4 + Sleep Patterns):

Stack:

  • Voyage-3-large embeddings (1024-dim, 9.74% better than OpenAI)
  • Qdrant HNSW index (M=16, int8 quantization, 4x compression)
  • RecursiveCharacterTextSplitter (semantic boundaries)
  • Dual-indexing (QNTM semantic keys + RFC 3339 timestamps)

Production Config (from Step 3 research):

  • Recall@10: >0.98
  • Latency: 10-50ms (p95)
  • Memory: 1.4GB RAM + 5GB disk per 1M vectors
