Tools & Capabilities Breakdown

Toon Memory Tools (35)

memory_remember

Save a decision, pattern, bug, knowledge, or **warning** (negative "do NOT do this" memory, recalled with a boost) — optional TTL, auto-tag inference, `links` to build the memory graph, merge-dedup on same key, auto quality score and confidence. **Write-path intelligence**: each save is annotated w…

memory_recall

Search memory (use BEFORE reading files, filters expired TTL). `mode: "graph"` expands a relationship-aware subgraph for higher precision. `budget: "tiny"

memory_smart_recall

Unified recall**: BM25 + graph + decay + quality in one call. `sessionBias` boosts entries from the current git branch. `explain: true` appends per-entry reasons, `budget_tokens` caps output by estimated tokens. Use at the START of every task. Returns compact, token-efficient output

memory_forget

Lifecycle ops** by key or id: `action: "soft"` (default) marks obsolete, `"hard"` permanently removes, `"restore"` brings back to active, `"supersede"` retires it with a `superseded_by` link to `new_key
