waf-detector: Instructions file for Codex

AGENTS.md

waf-detector AGENTS.md is an instructions file for Codex, OpenCode from ammarion/waf-detector. It costs 701 tokens per session, scanned A, original, Apache-2.0.

Repository-specific instructions for working on waf-detector. They describe the agent guidance, the authoritative source of information, the mapping, when to use each skill, and the project’s mental model.

In plain words
What is it for?
Use them when asking an agent to understand or modify the waf-detector repository.
Why use it?
They help an agent follow the repository’s intended sources and workflow instead of making assumptions about how its parts fit together.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; reads ~/.codex paths; mentions Codex.

This is ammarion/waf-detector's own configuration. It tells Codex and OpenCode how to work on waf-detector itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything waf-detector configures →

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

waf-detector 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.

Agent Guidance

This repository is meant to be comfortable for both Codex and Claude.

Source Of Truth

Shared agent workflows live under agent-skills/. These files contain the real workflow logic:

  • agent-skills/waf-assess/WORKFLOW.md
  • agent-skills/cli-doctor/WORKFLOW.md
  • agent-skills/security-audit/WORKFLOW.md
  • agent-skills/validate-build/WORKFLOW.md
  • agent-skills/codebase-explore/WORKFLOW.md
  • agent-skills/provider-dev/WORKFLOW.md

Agent-specific wrappers must stay thin:

  • Claude wrappers live in .claude/skills/*.md
  • Codex wrappers live in .codex/skills/*/SKILL.md

If a wrapper and a shared workflow disagree, follow the shared workflow and fix the wrapper in the same change.

Mapping

  • Full scan pipeline, detection, smoke, effectiveness, enforcement, behavioral review, posture reporting, and HTML report rendering: agent-skills/waf-assess/WORKFLOW.md
  • CLI health checks and shell completion setup: agent-skills/cli-doctor/WORKFLOW.md
  • Security review or audit work: agent-skills/security-audit/WORKFLOW.md
  • Build, lint, test, and release validation: agent-skills/validate-build/WORKFLOW.md
  • Codebase exploration, architecture review, streamlining opportunities: agent-skills/codebase-explore/WORKFLOW.md
  • Adding a new WAF/CDN provider: agent-skills/provider-dev/WORKFLOW.md

When to Use Which Skill

User says… Skill
"Assess this WAF" / "Full scan" / "Run detection" waf-assess
"Scans failing" / "Environment unhealthy" / "Shell completions" cli-doctor
"Security audit" / "Pre-release review" security-audit
"Validate before merge" / "Run tests" validate-build
"Streamline" / "Understand codebase" / "Find duplication" codebase-explore
"Add new provider" / "Implement detection for X" provider-dev

Mental Model

This project is AI-native agentic tooling. The skills are the primary interface — not the CLI. The CLI exists to serve the skills, not the other way around. When a user asks for a WAF assessment, an agent reads agent-skills/waf-assess/WORKFLOW.md and executes the steps; the user never needs to know the flag syntax.

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.
