## What it does

AI coding agents drop hard-won constraints as soon as their context window resets. Seamless retains that context on your local drive. The `seamlessd` background daemon stores records as plain Markdown files under `~/.seamless`, while an internal SQLite engine indexes tasks and events.

When dispatching several agents at once, the system prevents duplicate work. It provides an atomic leasing queue where workers reserve plan steps before executing them. Knowledge updates rely on explicit curation: an automated gardener spots stale entries or duplicates, yet only suggests revisions rather than rewriting files silently.

Everything runs locally through a standalone Go binary. No cloud accounts, external vector stores, or Node dependencies are required. The installer relies on `curl` and `tar`, and the background daemon must run as an active user service.

## Requirements
- Needs: a prebuilt binary from the repository releases

## Install

### Claude Code (native platform)

**Install**
- The MCP registry has no launch command for it: see the repository README

## When to use it
- persist learned architectural constraints across isolated agent sessions
- prevent multiple concurrent agents from implementing the exact same backlog item
- lease tasks atomically so parallel workers divide project workload cleanly
- audit and prune project memories through explicit human review

## Example prompts
- Record a constraint: always hash refresh tokens before saving them to the database
- Claim the next ready task from our refactoring roadmap with an active lease
- Read the project constraints before touching the session cookie settings
