The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
soulsketch_continuity_record Create a continuity record ~136
Build a full continuity record for a pack: fingerprint, per-file hashes, provenance labels (source, authority, trust), and provenance warnings. This is the audit artifact to store alongside the pack or anchor elsewhere.
| Name | Type | Req | Description |
|---|---|---|---|
| authority | string | – | How authoritative this pack state is |
| commit | string | – | Git commit hash pinning this state |
| pack_dir | string | yes | Absolute path to the memory pack directory |
| repo | string | – | Repository that owns this state |
| source | string | – | How the memory content was produced |
| trust_label | string | – | Sensitivity classification of the contents |
No output schema declared.
No examples provided.
soulsketch_diff_packs Diff two memory packs ~82
Compare two memory pack directories and explain WHICH identity dimension changed (persona, relationships, technical domains, voice, observations). Line-ending differences (CRLF vs LF) never count as identity changes.
| Name | Type | Req | Description |
|---|---|---|---|
| pack_dir_a | string | yes | Absolute path to the first pack directory |
| pack_dir_b | string | yes | Absolute path to the second pack directory |
No output schema declared.
No examples provided.
soulsketch_fingerprint_pack Fingerprint a memory pack ~70
Compute the deterministic SHA-256 identity fingerprint of a memory pack, plus per-file hashes. The fingerprint refers to a memory state without revealing its contents; use it for audit logs, handoffs, and continuity proofs.
| Name | Type | Req | Description |
|---|---|---|---|
| pack_dir | string | yes | Absolute path to the memory pack directory |
No output schema declared.
No examples provided.
soulsketch_observe Append a runtime observation ~167
Append ONE observation line to the pack's runtime_observations.jsonl (the living memory stream). This is the only write this server can perform: append-only, never modifying or deleting existing memories. MEMORY ETIQUETTE: when the conversation surfaces something memory-worthy (a durable preference, a decision, a milestone, a relationship change), FIRST ask the user, e.g. "Would you like me to save this to your Soul-Sanctum?" - and only call this tool after they agree. Never save silently; the user owns their memory.
| Name | Type | Req | Description |
|---|---|---|---|
| author | string | – | Who is recording this (e.g. assistant name) |
| note | string | yes | The observation to remember |
| pack_dir | string | yes | Absolute path to the memory pack directory |
No output schema declared.
No examples provided.
soulsketch_read_pack Read a memory pack ~144
Load the contents of a memory pack so the assistant can adopt its identity: persona, relationships, technical context, voice, and recent observations. Optionally restrict to specific files. ONE SOUL, MANY VESSELS: the pack is a single shared identity. If persona.md has a "Vessels" section listing a name for the tool you are running in, adopt that name (and use it as the author when observing) while keeping the shared persona, relationships, and voice.
| Name | Type | Req | Description |
|---|---|---|---|
| files | array | – | Optional subset of pack files to read (default: all five) |
| pack_dir | string | yes | Absolute path to the memory pack directory |
No output schema declared.
No examples provided.
soulsketch_validate_pack Validate a memory pack ~70
Check that a directory is a healthy 5-file SoulSketch memory pack (persona.md, relationship_dynamics.md, technical_domains.md, stylistic_voice.md, runtime_observations.jsonl). Returns errors and warnings.
| Name | Type | Req | Description |
|---|---|---|---|
| pack_dir | string | yes | Absolute path to the memory pack directory |
No output schema declared.
No examples provided.
