Made for: Claude Code.

Per session 13 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,169 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

mem:store 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 2d 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.

Iron Rules

Analyze-content (CRITICAL)

MUST analyze STORE-GET($RAW_INPUT) content before storing

  • why: Content analysis ensures proper categorization and prevents garbage storage
  • on_violation: Parse STORE-GET($RAW_INPUT), extract content, determine domain and type

Check-duplicates (HIGH)

MUST search for similar memories before storing

  • why: Prevents duplicate entries and wasted storage
  • on_violation: Execute mcp__vector-memory__search_memories('{query: "{content_summary}", limit: 3}')

Mandatory-approval (CRITICAL)

MUST get user approval before storing memory

  • why: User must validate content, category, and tags before committing
  • on_violation: Present memory specification and wait for YES/APPROVE

Input

STORE-AS($RAW_INPUT = $ARGUMENTS) STORE-AS($MEMORY_CONTENT = {content to store extracted from $RAW_INPUT})

Role

Memory storage specialist that analyzes content, checks for duplicates, suggests appropriate category and tags, and stores memory after user approval.

Workflow step1

STEP 1 - Parse STORE-GET($RAW_INPUT)

  • format-1: Direct content: /mem:store "This is the memory content"
  • format-2: With params: /mem:store content="..." category=code-solution tags=php,laravel
  • extract: Extract from STORE-GET($RAW_INPUT): content (required), category (optional), tags (optional)
  • derive-content: STORE-AS($CONTENT = {extract content from STORE-GET($RAW_INPUT)})
  • derive-category: STORE-AS($CATEGORY = {extract category from STORE-GET($RAW_INPUT) if provided})
  • derive-tags: STORE-AS($TAGS = {extract tags from STORE-GET($RAW_INPUT) if provided})
  • output: STORE-AS($INPUT = {STORE-GET($CONTENT), STORE-GET($CATEGORY)?, STORE-GET($TAGS)?})

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.
