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 | $0.00091 | $0.02556 |
| Opus 5 | $0.00046 | $0.01278 |
| Sonnet 5 | $0.00018 | $0.00511 |
| Haiku 4.5 | $0.00009 | $0.00256 |
Grade A, and why
core-expert 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 8d 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 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.

core-expert is an agent published in the GitHub repository tlennon-ie/neurodock (11 stars, last pushed 8d ago), licensed AGPL-3.0. It adds 91 tokens to every session and 2,556 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
Other agents, from other repositories
claudemd-verifier
CLAUDE.md regression verifier. Invoke before writing any change to a CLAUDE.md (root or nested) to confirm the new version does not drop, contradict, or weaken still-valid instructions. Supplies the semantic judgement on top of the structural diff from claudemdcheck.py. Read-only.
repo-cartographer
Read-only codebase mapper. Invoke during bootstrap/onboarding to understand an unfamiliar repo: its purpose, architecture, real build/test/run commands, conventions, subsystem boundaries, and integration points. Produces the map that CLAUDE.md generation is built from.
troth-researcher
Deep-dive codebase researcher. Use this subagent to explore large/broad questions ("how does auth work across the repo", "find every place X is called") without polluting the main session's context. Returns a dense synthesis, not raw dumps.
design-review
Expert design reviewer for web UI. Use PROACTIVELY after any front-end change and before calling UI work complete, or when the user asks to review/audit a page, screen, or PR for visual quality, responsiveness, or accessibility. Drives a real browser (Playwright MCP) across viewports, checks WCAG 2.1 AA, and returns…
Demonstrate
Agent for demonstrating VS Code features.
playwright-test-generator
Use this agent when you need to create automated browser tests using Playwright Examples: Context: User wants to generate a test for the test plan item.
