crystallise-memory

crystallise-memory is a skill for Claude Code from JamsusMaximus/agent-foundations-starter. It costs 142 tokens per session (1,383 once invoked), scanned A, original, no licence file.

A process for moving the assistant’s user-related knowledge into files the user owns and can reuse elsewhere. It reviews one category at a time, removes unreliable or unwanted details, and marks guesses for verification.

In plain words
What is it for?
It is for organizing user preferences and background into editable files, deciding what to keep or remove, and flagging information that still needs confirmation.
Why use it?
It makes personal context portable and easier to inspect, while reducing reliance on hidden memory and separating confirmed facts from assumptions.

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

crystallise-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 1mo 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 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.
