memory-bank

memory-bank is a skill for Claude Code from ils15/pantheon-legacy. It costs 20 tokens per session (1,355 once invoked), scanned A, original, MIT.

A structured project memory system for storing architecture, technology choices, progress, tasks, and notes in version-controlled files. It also distinguishes permanent team context from session-specific agent memories.

In plain words
What is it for?
Use it to maintain shared project context, track work and blockers, and record architectural decisions.
Why use it?
It gives coding agents durable project information instead of making them rediscover the same facts in every session.

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

memory-bank 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 8d 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.

Golden Rules

  1. Never create .md files outside .pantheon/memory-bank/ (except README.md, CONTRIBUTING.md)
  2. Never create ANALYSIS_*.md, SUMMARY_*.md, STATUS_*.md anywhere
  3. 01-active-context.md is the priority file — keep it current
  4. 02-progress-log.md is append-only — never edit history
  5. _notes/ decisions are immutable — supersede, never edit

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.
