Codex flagged (review 4397232451) that the hooks locate the CLI via `command -v basic-memory || command -v bm`, but our own README recommends connecting the MCP server as `claude mcp add basic-memory -- uvx basic-memory mcp` — an ephemeral uv run that leaves NO binary on PATH. In that (recommended) setup both hooks exited before doing anything, so the bridge silently did nothing even though the MCP server worked. Both hooks now resolve the CLI invocation as: prefer a `basic-memory`/`bm` binary (fast), else fall back to `uvx basic-memory`, else `uv tool run basic-memory`, else silent no-op. The launcher may be multi-token, so the embedded Python splits it with shlex and prepends it to each command list. The uv cache is already warm from running the MCP server, so the fallback is cheap. Verified: with no binary on PATH but uvx present, SessionStart now produces a brief (previously a silent no-op). Updated the README requirement to note uvx-only works.

Basic Memory for Claude Code
The bridge between Claude's working memory and Basic Memory's durable knowledge graph.
Claude Code now keeps its own auto-memory — fast, in-context notes Claude writes to itself. Basic Memory is the other half: a searchable, portable, semantic graph of markdown files you and Claude both own. This plugin connects the two so you get the documented "use both" setup automatically: Claude starts each session briefed from the graph, and checkpoints the session back to it before the context window compacts.
This package lives in the canonical
basic-memoryrepository underplugins/claude-code/and only works with Claude Code. For framework-agnostic skills that work in any MCP agent, see the top-levelskills/directory.
What it does
- Session briefing (SessionStart hook). When a session begins, the plugin queries Basic Memory for your active tasks and recent work and puts a short brief in front of Claude — so you start where you left off instead of cold.
- Compaction checkpoint (PreCompact hook). Right before Claude Code compacts
the context window, the plugin writes a
type: sessioncheckpoint note to the graph, so the texture of the session survives and the next one can resume from it. - Capture reflexes (output style). An opt-in output style teaches Claude to
search the graph before answering recall questions, capture real decisions as
typed
decisionnotes, and cite permalinks. - Seed schemas. Picoschema definitions for
session,decision, andtasknotes, so the stuff the plugin writes is structured and findable bysearch_notesmetadata filters — recall is precise, not fuzzy.
The full design and rationale live in DESIGN.md.
Commands
Plugin skills are namespaced under the plugin name:
| Command | What it does |
|---|---|
/basic-memory:setup |
One-time guided setup — maps the project to a Basic Memory project, seeds the note schemas, installs the shared memory-* skills, optionally learns your conventions, and turns on the capture reflexes. Run this first. |
/basic-memory:remember <text> |
Quick capture — saves the text to the bm-remember folder with a manual-capture tag. Also fires when you say "remember that…". |
/basic-memory:share <note> |
Promote a personal note to a configured team project, with attribution and confirmation. The deliberate way to write to a shared workspace. |
/basic-memory:status |
Diagnostic — shows the active project, team read-sources and share targets, capture folders, output-style state, recent session checkpoints, and active-task count. |
Requirements
- Basic Memory
>= 0.19.0connected as an MCP server.uv tool install basic-memoryis recommended (it puts abasic-memorybinary on PATH, which the hooks call directly). Auvx basic-memory mcp-only setup also works — the hooks fall back touvx/uvwhen no binary is on PATH. - Claude Code.
Installation

Configuration
The fastest path is /basic-memory:setup — a ~2-minute interview that writes
the config, seeds the schemas, and turns on the capture reflexes. The SessionStart
hook nudges you toward it on first run.
To configure by hand instead: the hooks work out of the box against your default
Basic Memory project — no config required. To pin a specific project (recommended,
and required for the PreCompact checkpoint to write), add a basicMemory block to
your project's .claude/settings.json. Copy
settings.example.json and set primaryProject:
{
"basicMemory": {
"primaryProject": "my-project",
"captureFolder": "sessions"
}
}
To enable the capture reflexes, also set "outputStyle": "basic-memory" in your
settings (or select it via /config).

Teams
If you're on Basic Memory Cloud with a team workspace, the plugin reads team context into your session brief and gives you a deliberate way to publish back — without ever auto-writing to the shared graph.
- Read across — add team projects to
secondaryProjects. SessionStart pulls their open decisions into your brief (in parallel, read-only), so you start oriented on what the team has decided. - Capture stays personal — session checkpoints and
/basic-memory:rememberonly ever write to yourprimaryProject. Nothing lands in a team project automatically. - Share deliberately —
/basic-memory:sharecopies a chosen note into ateamProjectstarget (with attribution and a confirmation step). That's the only path to a shared write.
Because project names repeat across workspaces, team refs must be workspace-qualified
(my-team/notes) or external_id UUIDs — /basic-memory:setup fills these in for you
from list_workspaces.
