borgmemory CLAUDE.md

borgmemory CLAUDE.md is an instructions file for coding agents from villanub/borgmemory. It costs 304 tokens per session, scanned A, original, Apache-2.0.

A project guide for Borg, a repository memory system that stores and retrieves project context, decisions, and lessons.

In plain words
What is it for?
Use it before complex work, debugging, architecture decisions, or documentation, and after significant decisions or non-obvious fixes.
Why use it?
It tells the coding agent when to recall prior context and when to save important discoveries for later sessions.

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 A, and why

borgmemory CLAUDE.md scanned grade A with 0 findings 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 3d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

CLAUDE.md — Project Borg

Borg Namespace

For this repository, use Borg namespace borg.

Always pass namespace="borg" to:

  • borg_think
  • borg_learn
  • borg_recall

Do not omit the namespace. Do not use default for work in this repository.

When to use Borg

borg_think

Call borg_think before complex tasks to retrieve relevant project context, prior decisions, and working patterns.

Use:

  • When starting work on a file or module you have not touched in the current session
  • When debugging
  • When making architecture or design decisions
  • When writing docs, proposals, or project explanations

Example:

borg_think(
    query="Project Borg repository context, recent decisions, and active development areas",
    namespace="borg",
    task_hint="architecture",
)

borg_learn

Call borg_learn after significant decisions, discoveries, or non-obvious fixes that should persist across sessions.

Example:

borg_learn(
    content="Fixed Borg issue. Root cause was ... Solution was ...",
    source="claude-code",
    namespace="borg",
)

borg_recall

Call borg_recall for direct searches when you want raw memory rather than compiled context.

Example:

borg_recall(
    query="OSS release cleanup",
    namespace="borg",
    memory_type="semantic",
)
Changes

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.
