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 | $0.00769 | $0.00769 |
| Opus 5.5 | $0.00308 | $0.00308 |
| Sonnet 5.5 | $0.00154 | $0.00154 |
| Haiku 4.5 | $0.00077 | $0.00077 |
Grade A, and why
spark-web AGENTS.md 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.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

⚠️ This file has been migrated to the modern structure
This project now uses Cursor's Rules, Skills, and Subagents structure for better AI agent support:
- Rules (
.cursor/rules/): Always-applied project standards
project-overview.md- Project architecture and overviewcomponent-guidelines.md- Component development standardscode-style.md- Code conventions and workflowaccessibility-standards.md- WCAG 2.1 AA compliance standards- Skills (
.cursor/skills/): Task-specific instructions
create-component/- Create a new component with full structuregenerate-tests/- Generate unit tests for componentscreate-storybook-docs/- Create Storybook stories and documentationcheck-accessibility/- Verify accessibility compliancerun-quality-checks/- Run all quality checks (lint, typecheck, tests)- Subagents (
.cursor/agents/): Specialized agents for complex tasks
component-reviewer.md- Review components for compliancerefactoring-assistant.md- Assist with component refactoringCross-Platform Compatibility
For Claude Code compatibility, symlinks are available:
.claude/skills/→ symlinked to.cursor/skills/.claude/agents/→ symlinked to.cursor/agents/Usage
- In Cursor: Rules are automatically applied, Skills can be invoked with
/skill-name- In Claude Code: Skills in
.claude/skills/are automatically available- Universal fallback: This file serves as a reference for tools that look for

General Guidelines for working with Nx
- For navigating/exploring the workspace, invoke the
nx-workspaceskill first - it has patterns for querying projects, targets, and dependencies - When running tasks (for example build, lint, test, e2e, etc.), always prefer running the task through
nx(i.e.nx run,nx run-many,nx affected) instead of using the underlying tooling directly - Prefix nx commands with the workspace's package manager (e.g.,
npm exec nx build,npm exec nx test) - avoids using globally installed CLI - You have access to the Nx MCP server and its tools, use them to help the user
- For Nx plugin best practices, check
node_modules/@nx/<plugin>/PLUGIN.md. Not all plugins have this file - proceed without it if unavailable. - NEVER guess CLI flags - always check nx_docs or
--helpfirst when unsure
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.

spark-web AGENTS.md is an instructions file published in the GitHub repository leboncoin/spark-web (94 stars, last pushed 2d ago), licensed MIT. It adds 769 tokens to every session, about $0.0031 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 2026-09-05.
