update-memory

update-memory is a command for Claude Code from hudrazine/claude-code-memory-bank. It costs 7 tokens per session (881 once invoked), scanned A, original, Unlicense.

A command that reviews and updates Memory Bank files with important project changes, discoveries, decisions, and progress.

In plain words
What is it for?
Use it after significant changes or completed work to record the project's current state.
Why use it?
It keeps project context accurate so later coding sessions do not lose important information.

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

update-memory 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 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.

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.

Memory Bank Documentation Update

Task

Think longer about project evolution and comprehensively review all Memory Bank files to preserve important learnings, decisions, and project state for future Claude Code sessions. Ensure they accurately reflect the current project state and recent developments.

Process

1. Comprehensive Review

Review all Memory Bank files in order:

  1. projectbrief.md - Core project information
  2. productContext.md - Product decisions and user experience
  3. systemPatterns.md - Architecture and design patterns
  4. techContext.md - Technologies and tools
  5. activeContext.md - Current focus and next steps
  6. progress.md - Development milestones and status

2. Update Criteria

Document changes when:

  • New patterns established: Coding patterns, architectural decisions, workflows
  • Significant features completed: Major functionality, integrations, systems
  • Important discoveries made: Technical insights, constraint clarifications, solutions
  • Project direction changes: Scope adjustments, priority shifts, approach changes
  • Challenges resolved: How problems were solved for future reference

3. Update Guidelines

For projectbrief.md:

  • Core requirements changes
  • Scope adjustments
  • Major goal revisions
  • Fundamental constraint updates

For productContext.md:

  • User experience insights
  • Problem definition refinements
  • Solution approach changes
  • Value proposition updates

For activeContext.md:

  • Current development phase and focus
  • Recently completed work
  • Active challenges and blockers
  • Next priority actions
  • Important decisions in progress

For progress.md:

  • Feature completion status
  • Development milestone achievements
  • Recent updates with dates
  • Current challenges and risks

For systemPatterns.md:

  • New design patterns adopted
  • Architectural decisions made
  • Integration approaches established
  • Security or performance patterns

For techContext.md:

  • New technologies added
  • Configuration changes
  • Development workflow updates
  • Environment setup 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.
