brainctl CLAUDE.md

brainctl CLAUDE.md is an instructions file for coding agents from TSchonleber/brainctl. It costs 6,112 tokens per session, scanned B, original, MIT.

Project instructions for brainctl, an agent-memory system that stores information in a database and provides command-line and MCP access. MCP is a standard way for an AI agent to use external tools.

In plain words
What is it for?
It helps maintain and use the brainctl and agentmemory codebase, including its database, command-line program, MCP server, and project-specific setup.
Why use it?
It gives developers one reference for the system's files, database, build and test process, migrations, and available tools.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

brainctl CLAUDE.md scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Claude Code — brainctl / agentmemory

What This Is

Unified agent memory system. SQLite-backed (brain.db) with FTS5, vector embeddings (sqlite-vec + Ollama nomic-embed-text), knowledge graph, affect tracking, belief collapse mechanics, and AGM conflict resolution.

Published as brainctl on PyPI (v2.2.1+, current 2.4.10).

Key Paths

  • DB: db/brain.db (WAL mode, foreign keys ON, 59 user-facing tables, 49 numbered migrations + one unnumbered V2-4 quantum-schema file). The numbered sequence has an intentional gap at 050 — the V2-4 quantum schema (db/migrations/quantum_schema_migration_sqlite.sql) occupies that slot without a number because it was applied ad-hoc during the V2-4 rollout and pre-dates the idempotent runner fix in 2.4.8. The runner only picks up files matching ^\d+_.+\.sql$ so the quantum file is a no-op for brainctl migrate on fresh installs — apply manually if you need the quantum columns on a new DB. (Audit I28 — 2026-04-19.)
  • CLI: bin/brainctl — main CLI entry
  • MCP server: canonical entry is agentmemory.mcp_server:run. As of v2 surface consolidation (2026-05-20): 100 visible tools (370 registered internally; 270 hidden behind action-discriminated dispatchers). Installed as the brainctl-mcp console script via pip. See MCP_SERVER.md for the tool reference and docs/TOOL_MIGRATION_V2.md for v1→v2 migration. The legacy standalone bin/brainctl-mcp only registers a subset and is being phased out.
  • Bench: bin/brainctl-bench — retrieval eval harness (P@k / MRR / nDCG@k regression gate, fixtures under tests/bench/)
  • Source: src/agentmemory/ — Python package
  • Config: config/ — quiet hours, consolidation schedules
  • Agents: agents/ — per-agent config (pipeline, engram, etc.)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

brainctl CLAUDE.md is an instructions file published in the GitHub repository TSchonleber/brainctl (79 stars, last pushed 28d ago), licensed MIT. It adds 6,112 tokens to every session, about $0.0306 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
