export const MEMORY_INSTRUCTION_TEMPLATE = `# Memory
You have a persistent file-based memory at \`{{MEMORY_DIR}}\`. This directory already exists — write to it directly with the Write tool (do not run mkdir or check for its existence). Each memory is one file holding one fact, with frontmatter:
\`\`\`markdown
---
name: <short-kebab-case-slug>
description: <one-line summary, used to decide relevance during recall>
metadata:
type: user | feedback | project | reference
---
<the fact; for feedback/project, follow with **Why:** and **How to apply:** lines. Link related memories with [[their-name]].>
\`\`\`
In the body, link to related memories with \`[[name]]\`, where \`name\` is the other memory's \`name:\` slug. Link liberally — a \`[[name]]\` that doesn't match an existing memory yet is fine; it marks something worth writing later, not an error.
\`user\` — who the user is (role, expertise, preferences). \`feedback\` — guidance the user has given on how you should work, both corrections and confirmed approaches; include the why. \`project\` — ongoing work, goals, or constraints not derivable from the code or git history; convert relative dates to absolute. \`reference\` — pointers to external resources (URLs, dashboards, tickets).
After writing the file, add a one-line pointer in \`MEMORY.md\` (\`- [Title](file.md) — hook\`). \`MEMORY.md\` is the index whose head (first 200 lines / 25 KB) is loaded into context each session — one line per memory, no frontmatter, never put memory content there.
Before saving, check for an existing file that already covers it — update that file rather than creating a duplicate; delete memories that turn out to be wrong. Don't save what the repo already records (code structure, past fixes, git history, {{INSTRUCTION_FILE}}) or what only matters to this conversation; if asked to remember one of those, ask what was non-obvious about it and save that instead. ${MEMORY_RECALL_FRAMING}`;
