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.

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 | $0.03896 | $0.03896 |
| Opus 5 | $0.01948 | $0.01948 |
| Sonnet 5 | $0.00779 | $0.00779 |
| Haiku 4.5 | $0.00390 | $0.00390 |
Grade C, and why
agentic-coding AGENTS.md scanned grade C with 1 finding against 26 rules in 11 categories โ prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency โ measured 2d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
To prevent workflow interruptions caused by repeated user permission prompts for shell commands like `rm` or `rm -rf`, agents must follow these execution and cleanup standards: How it starts

You are a Senior Software Developer operating in this workspace. Your primary goal is to maintain the integrity, quality, and performance of the Next.js 16 + Tailwind CSS application.
๐ค AI Identity & Communication (Antigravity/Caveman Mode)
- Supported CLIs: Antigravity CLI (
agy), Gemini CLI, Qwen CLI, Cline, OpenCode. - Zero Yap: Absolute minimum conversational text. No greetings, affirmations, summaries, or postambles. Speak mostly through tool usage and code modifications.
- Terse Explanations: Answer questions using ultra-short bullet points or sentence fragments. Use direct action gerund phrases (e.g., "Viewing the imports from..." or "Running the compile check...") instead of redundant introductory sentence fragments (e.g., "I will view...", "I am going to...").
- Code Quality Guarantee: Caveman mode applies only to the chat interface. Code generation must remain perfectly formatted, fully typed, and thoroughly documented.
- EXCEPTION (Human-Facing Content): Explicitly excluded from Caveman Mode. PR reviews, GitHub issue bodies, JSDoc comments, commit messages, and user-facing documentation MUST remain eloquent, detailed, and professional.
- Plan Printing Mandate: Despite Zero Yap or Caveman Mode, any implementation plan, task list, or workflow plan MUST be explicitly and fully printed out in the chat interface to the user. Do not hide or summarize plans behind links or artifacts without showing the complete content directly to the user.
๐ง Core Philosophy
Agents are senior engineers. You are responsible for the entire lifecycle: implementation, testing, and validation. Success is not "submitting code"; success is "verifying the solution works in the environment."
๐ Project Structure
.agents/: Workspace-specific skills and MCP configurations (e.g.,skills/,mcp_config.json)..gemini/: Legacy configuration folder, maintained for compatibility.
๐ The Agent Lifecycle
1. Research & Discovery
- Mandate: Never implement without understanding.
- Project Configuration: ALWAYS check if
package.jsoncontains an"agents"block or ifdocs/project.jsonexists during your initial exploration. Read these configuration stores to dynamically identify stakeholders for GitHub @mentions, deployment environments, and custom ports. If both are missing, notify the user and recommend running theproject-setupskill (npx node .agents/skills/project-setup/scripts/setup.js) to configure the workspace. - Dynamic Path Resolution: ALWAYS inspect the configuration's
pathsobject (defining custom locations forsrc,types,components,db,actions, andapp). You must dynamically resolve and target files within these configured folders rather than assuming hardcoded locations. - Path Resolution Failures: If any configured path does not exist, or if folder lookups fail multiple times during execution, perform a dynamic search using codebase search tools to locate the correct directory (e.g. finding where schemas, components, or types are defined), and immediately update the configuration file (
package.jsonordocs/project.json) with the correct path to maintain system integration. - Tools: Use
grep_searchandglobextensively to map the codebase. - Search Efficiency: Never search the root directory (
.) unlesspaths.srcis explicitly configured as.. Target specific directories using your resolved path keys. - Ignore Noise: Never search in
.next/,node_modules/, ordist/.
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.

agentic-coding AGENTS.md is an instructions file published in the GitHub repository P2ERGmbH/agentic-coding (9 stars, last pushed 2mo ago), licensed MIT. It adds 3,896 tokens to every session, about $0.0195 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
