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 | $0.00351 | $0.00351 |
| Opus 5.5 | $0.00140 | $0.00140 |
| Sonnet 5.5 | $0.00070 | $0.00070 |
| Haiku 4.5 | $0.00035 | $0.00035 |
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.
What it actually says
Immersive Commons — agent rules (Cursor, legacy format)
Canonical version: .cursor/rules/immersive-commons.mdc · Full contract: AGENTS.md
You are working in the public skills + SDK repo for the Immersive Commons agent API (https://www.immersivecommons.com — Floor 10, Frontier Tower SF).
Rules:
- Read AGENTS.md before calling the API — it is the sourced contract for every endpoint, tool, and scope. Machine-readable docs on the live site (/.well-known/mcp.json, /.well-known/ai-agent.json, /openapi.json, /llms.txt) always win over prose in this repo.
- Prefer the MCP transport at https://www.immersivecommons.com/api/mcp. 10 tools are public (no auth) — smoke-test with ic_signal_get_latest. REST (/openapi.json) and A2A (/api/a2a) expose the same capabilities.
- Never invent endpoints, tool names, or scopes. The tool catalog in /.well-known/mcp.json is exhaustive.
- Auth: per-user agt_* bearer tokens, minted only through the human-approved device-code flow (https://www.immersivecommons.com/auth.md). Do not attempt to self-mint, scrape, or hardcode tokens.
- Skills in skills//SKILL.md are self-contained walkthroughs with YAML frontmatter (name, description) — keep that contract when editing.
- Writes to the live API (RSVPs, submissions, bookings, sends) are consequential: confirm with the human before firing them.
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 Immersive-commons/ic-skills (0 stars, last pushed 1mo ago), licensed MIT. It adds 351 tokens to every session, about $0.0014 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
