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 | $0.00343 | $0.00343 |
| Opus 5.5 | $0.00137 | $0.00137 |
| Sonnet 5.5 | $0.00069 | $0.00069 |
| Haiku 4.5 | $0.00034 | $0.00034 |
Grade A, and why
cursorrules 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
100% identical to smolagents_rules — 40 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.
What it actually says
# Cursor Rules for Prism-Mem Project
## Project Purpose
- Build a knowledge graph generation system that extracts and links structured triples from coding sessions
- Store session transcripts and maintain persistent knowledge state across Claude interactions
## Key Technology Stack
- Use Claude/Haiku API via LiteLLM for triple extraction
- Use SQLite with sqlite-vec extension for embeddings storage
- Use transformer models for generating embeddings
- Store sessions in ~/.claude/history.jsonl and ~/.claude/projects/*.jsonl files
## Architecture Rules
- Implement extraction in phases, with Phase 4 following Phase 3 and Phase 7 (constitution generator) at the end
- Use session_reader.py to extract sessionId from transcripts
- Use git_reader.py to implement read_git_diff for source analysis
- Store all knowledge graphs in prism-mem located at Desktop/Projects
## Key Components
- extractor module calls Haiku API and produces Graph.relations
- Use link_triple to call create_edge() when connecting entities
- Apply similarity threshold during entity linking phase
- Phase 7 scores all generated triples
## Authentication & API
- Authenticate Anthropic API with ANTHROPIC_API_KEY environment variable
- Pass prompts to _call_haiku for model inference
## Session Management
- Subagent sessions maintain separate .jsonl files in ~/.claude directory
- Subagents produce tool_result objects for parent agent consumption
- Parse JSON objects with attachment field for file/context references
## Code Conventions
- Never hardcode API keys; use environment variables
- Always validate Graph.relations output from kg-gen phases
- Use role="user" for session differentiation where applicable
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.

cursorrules is a cursor rule published in the GitHub repository rahult18/prism-mem (3 stars, last pushed 4mo ago), licensed MIT. It adds 343 tokens to every session, about $0.0014 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to smolagents_rules, differing in 40 lines, and is treated as a copy.
