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 | $0.00032 | $0.01301 |
| Opus 5 | $0.00016 | $0.00651 |
| Sonnet 5 | $0.00006 | $0.00260 |
| Haiku 4.5 | $0.00003 | $0.00130 |
Grade B, and why
frontend-specialist scanned grade B with 1 finding 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 11d 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.
Unrestricted tool accessmediumExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

🔒 ISMS Policy Alignment
| TypeScript practice | Policy linkage |
|---|---|
No any / strict null checks |
Secure Development Policy — input validation |
| Zod schemas as single source of truth | Secure Development Policy — runtime validation |
| Branded types for MEP IDs / procedure refs | Data Classification Policy — typed boundaries |
import type + tree-shaken deps |
Open Source Policy — minimal attack surface |
| Narrow error types, generic outward errors | Information Security Policy — no information leakage |
| Exhaustive switch on discriminated unions | Secure Development Policy — defect reduction |
readonly + immutability where possible |
Security by design |

- TypeScript Strict Mode:
strict,strictNullChecks,noImplicitAny,noUncheckedIndexedAccess,exactOptionalPropertyTypes,noImplicitOverride, ES2025 target - Type-Safe Patterns: Branded types, discriminated unions, template literal types,
satisfies, utility types (Pick/Omit/Required/ReadonlyDeep) - Runtime ↔ Type bridge: Zod →
z.infersingle source of truth,safeParseoverparseat trust boundaries - API Client Development: Type-safe HTTP clients, request/response contracts, error taxonomy
- MCP Server Implementation: Tool/resource/prompt type contracts, handler signatures, response shapes
- Testing with Vitest: Type-safe mocks (
vi.mocked), schema tests, fake timers, fixture typing
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.
- 11d ago First seen · 98 lines · 32 tokens per session scan B 9531ded4bff5
frontend-specialist is an agent published in the GitHub repository Hack23/European-Parliament-MCP-Server (28 stars, last pushed yesterday), licensed Apache-2.0. It adds 32 tokens to every session and 1,301 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
