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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00041 | $0.02352 |
| Opus 5.5 | $0.00016 | $0.00941 |
| Sonnet 5.5 | $0.00008 | $0.00470 |
| Haiku 4.5 | $0.00004 | $0.00235 |
Grade A, and why
store-neotoma 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.
This is a copy
97% identical to store-neotoma — 21 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

store-neotoma
Purpose
Define the workflow for reviewing chat, building a Neotoma store preview, and executing storage after user confirmation. Neotoma is the only data store; there is no Parquet migration phase.
Canonical location: foundation/.cursor/skills/store-neotoma/SKILL.md (foundation git submodule). Consumer repos may symlink or copy this into .cursor/skills/store-neotoma/ via setup_cursor_copies / setup_cursor_rules.
Scope
Applies when the user asks to store the current chat in Neotoma. Covers preview, user revisions, confirmation, storage, and relationships. Excludes one-off store operations without preview.
Reviews the current chat conversation, builds a preview of records to store in Neotoma, waits for user confirmation (or revision input), then stores conversation, two agent_message entities per logical turn (role: "user" and role: "assistant"), each with PART_OF → conversation — the canonical shape from Neotoma MCP live chat instructions — plus attachments.
Preview-before-execute: On first run, this workflow MUST preview what will be stored and MUST NOT execute storage until the user confirms. User input (corrections, scope changes, exclusions) MUST be applied to revise the preview.
Prerequisites
- Chat transcript available in agent context (user and agent messages).
- Neotoma MCP available.
- Load

Phase 0: Preview (MANDATORY — Execute First)
Step 0.1 — Extract and build preview
Parse all user and agent messages in the conversation. For each logical turn (user message + following assistant reply):
- User row (preview + store):
entity_type: agent_message,role: "user",content= exact user text,turn_key(stable per turn), optionalturn_number(1-based),timestamp,files_modified,tools_used,platform,model,neotoma_operations(inferred from the turn). - Assistant row (preview + store):
entity_type: agent_message,role: "assistant",content= exact assistant text shown in chat,turn_keye.g. same base +:assistant, optional sameturn_number/timestampfor sorting. - Topics: extract from user questions, entity types discussed, file paths, domain keywords (finance, admin, health, work).
- Decisions: extract when agent states an approach, user confirms a choice, or implementation strategy is chosen.
- Action items: tasks to create, follow-ups mentioned.
files_modified: file paths from tool calls, @-mentions, or explicit file references (typically attributed to the user message for that turn).neotoma_operations: inferred from agent tool-call patterns (store_structured,correct,create_relationship).
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.

store-neotoma is a skill published in the GitHub repository markmhendrickson/foundation (2 stars, last pushed 2mo ago), licensed MIT. It adds 41 tokens to every session and 2,352 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 97% identical to store-neotoma, differing in 21 lines, and is treated as a copy.
