Every Claude session starts fresh. You explain your auth system. Again. Your database schema. Again. That bug you fixed last week. Again.
```
Before SpecMem: With SpecMem:
+----------------------------+ +----------------------------+
| "Hey Claude, remember the | | "Fix the auth bug" |
| auth module uses JWT with | | |
| refresh tokens and the | | Claude already knows: |
| edge case where expired | | - Your auth architecture |
| tokens need to..." | | - The JWT refresh flow |
| | | - Past bugs you fixed |
| [500 tokens of context] | | - Your code patterns |
+----------------------------+ +----------------------------+
| CLAUDE.md Limitation | SpecMem Solution |
|---------------------|------------------|
| Static - doesn't update as code changes | File watcher auto-updates on every save |
| Keyword search only | Semantic search finds by meaning |
| One monolithic file | Structured memories with types, tags, importance |
| Cross-project pollution | Per-project isolation with separate schemas |
| Manual maintenance | Auto-extraction from your Claude sessions |

`bash1. Install
npm install -g specmem-hardwicksoftware
That's it. Claude now has memory.
$3
`bash
claude
`Ask Claude: "What do you remember about this project?"
If working, Claude will mention SpecMem and show indexed files.
$3
`bash
specmem status
`Expected output:
`
PostgreSQL Running (port 5432)
Embedding Running (Docker)
File Watcher Active (monitoring 1,234 files)Memory Stats: 156 memories, 89 code files indexed

Why Root?
SpecMem isn't a simple npm package you drop into a project folder - it's a system-level tool that touches a lot of stuff your regular user account can't reach. Here's what it actually does and why it can't work without root:
- System-wide hooks get installed to
~/.claude/hooks/ - these intercept and augment tool calls in real-time. They aren't project-scoped, they're user-scoped, and writing to those directories from a global install needs elevated permissions.
- Docker container management - SpecMem spins up PostgreSQL with the pgvector extension in Docker. It creates containers, manages volumes, and handles networking. Docker's socket (/var/run/docker.sock) typically requires root or docker group membership.
- Global npm directories - installing to /usr/local/lib/node_modules/ and linking binaries to /usr/local/bin/ means writing to system paths. That's just how global npm packages work on Linux.
- Screen sessions for background services - the embedding server, file watcher, and MCP server all run in detached screen sessions. Managing those system-wide requires the right permissions.
- PostgreSQL database setup - first-run creates the database, enables pgvector, runs migrations, and sets up per-project schemas. It's touching system-level database configs.
- File watching across your entire codebase - chokidar watches thousands of files and needs access to whatever directories you're working in.Bottom line: if you want semantic search with vector embeddings, code memorization across sessions, 60% token compression, multi-agent team coordination, and a local embedding server that doesn't phone home - all of that needs to run as system services, and system services need root. There's no way to fake it with a local install.

You type: "that function that handles rate limiting for the API"SpecMem finds: rateLimiter(), handleThrottle(), apiQuotaManager()
+ related conversation context where you discussed them
`Traditional search needs exact function names. SpecMem understands what you're looking for.

Run 5 different projects simultaneously. Each gets:
| Component | Isolation |

| Database | Separate PostgreSQL schema (
specmem_{hash}) |
| Embeddings | Dedicated embedding service per project |
| Sockets | Project-specific Unix sockets |
| Memories | No cross-contamination between projects |$3
