spark-web AGENTS.md

spark-web AGENTS.md is an instructions file for Codex, OpenCode from leboncoin/spark-web. It costs 769 tokens per session, scanned A, original, MIT.

A set of project instructions for coding agents working on the Spark web project, including code standards, accessibility rules, generators, skills, and subagents.

In plain words
What is it for?
It is for creating components, generating tests and Storybook documentation, checking accessibility, running quality checks, and reviewing or refactoring components.
Why use it?
It tells an agent where project rules and task-specific guidance live, reducing inconsistent changes and missed quality checks.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

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.

Security

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 today.

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.

⚠️ 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 overview
    • component-guidelines.md - Component development standards
    • code-style.md - Code conventions and workflow
    • accessibility-standards.md - WCAG 2.1 AA compliance standards
  • Skills (.cursor/skills/): Task-specific instructions
    • create-component/ - Create a new component with full structure
    • generate-tests/ - Generate unit tests for components
    • create-storybook-docs/ - Create Storybook stories and documentation
    • check-accessibility/ - Verify accessibility compliance
    • run-quality-checks/ - Run all quality checks (lint, typecheck, tests)
  • Subagents (.cursor/agents/): Specialized agents for complex tasks
    • component-reviewer.md - Review components for compliance
    • refactoring-assistant.md - Assist with component refactoring

Cross-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 AGENTS.md

See .cursor/README.md for more details.

General Guidelines for working with Nx

  • For navigating/exploring the workspace, invoke the nx-workspace skill 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 --help first 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.
