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 | $0.00537 | $0.00537 |
| Opus 5.5 | $0.00215 | $0.00215 |
| Sonnet 5.5 | $0.00107 | $0.00107 |
| Haiku 4.5 | $0.00054 | $0.00054 |
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
Project Context
Lookup strategy
A pre-built index lives in
.codebeacon/. Use the 3-step lookup below before reaching for Glob or Grep.
Repo type:
single— Single-project repo.
Step 1 — codebeacon wiki
Routes, controllers, services, entities.
.codebeacon/wiki/index.md ← global index
.codebeacon/wiki/{project}/controllers/{Name}.md ← controller logic
.codebeacon/wiki/{project}/services/{Name}.md ← service methods
.codebeacon/wiki/{project}/entities/{Name}.md ← data models
.codebeacon/wiki/routes.md ← all API routes across projects
Step 2 — obsidian notes
Class-level detail (methods, fields, incoming/outgoing edges) the wiki omits.
Look up by class name — replace {project} with the relevant folder:
.codebeacon/obsidian/{project}/{ClassName}.md
| Project | Notes | Example |
|---|---|---|
| codebeacon | 413 services, 3 entities | affected_from_paths.py.md |
Step 3 — source file
Open the paths surfaced by Steps 1–2.

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 Wandererer/codebeacon (2 stars, last pushed 13d ago), licensed MIT. It adds 537 tokens to every session, about $0.0021 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.

This project has hypergrep installed globally. Use it instead of grep/ripgrep when you need structural understanding of code (function bodies, call graphs, impact analysis). For simple text searches, ripgrep is fine.
