build-like-amazon-agent-skills AGENTS.md

build-like-amazon-agent-skills AGENTS.md is an instructions file for Codex, OpenCode from robisson/build-like-amazon-agent-skills. It costs 3,772 tokens per session, scanned A, original, MIT.

A set of instructions for AI agents working with a library of reusable skills. It explains how to find the right skill, load it, and follow its required workflow.

In plain words
What is it for?
Use it to route requests to skills, handle slash commands, and apply the skill library's operating rules.
Why use it?
It reduces guesswork when several skills or workflows might apply to a request. It also defines what the agent should do when the correct path is unclear.

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

build-like-amazon-agent-skills 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 5d 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.

Instructions for AI Agents

This document defines how AI agents should discover, load, and execute skills from this repository. Follow these instructions precisely — they are the operating contract between this skill library and any agent that uses it.

Discovering Skills

Skills are located in the skills/ directory. Each skill is a standalone markdown file with YAML frontmatter containing metadata.

How to Find the Right Skill

  1. Check the command: If the user invokes a slash command (e.g., /wb, /design, /deploy), load the corresponding skill file directly.
  2. Use the meta-skill when no command is clear: If there is no slash command and the right workflow is unclear, read skills/using-amazon-skills/SKILL.md first. Use it to route the request to the correct lifecycle phase and skill chain.
  3. Check triggers: Each skill's frontmatter contains triggers — natural language phrases that indicate the skill should be activated.
  4. Check the phase: If you know what lifecycle phase the work is in, browse skills in that phase.
  5. When in doubt, ask: If multiple skills could apply after consulting the meta-skill, ask the user which workflow they want to follow rather than guessing.

Skill Loading Protocol

When a skill is activated:

  1. Read the full skill file
  2. Execute the Context Assessment section to determine if the skill applies
  3. If it applies, follow the Process section step by step
  4. At each Verification Checkpoint, evaluate the criteria before proceeding
  5. If a blocking checkpoint fails, stop and surface the issue to the user
  6. When complete, confirm all verification checkpoints have been met

Operating Behaviors

These behaviors apply whenever you are operating under this skill library. They are non-negotiable.

0. Respect Approval Gates

When a skill specifies a human approval gate, you MUST pause and present your work. Do not proceed until the user explicitly approves. This applies to:

  • Working Backwards (/wb): Each of the 5 stages (Listen → Define → Invent → Refine → Test) has a mandatory gate. Complete one stage, present the output, ask the user to review, and wait for explicit approval before advancing.
  • Spec creation (/design): Each artifact (requirements.md → design.md → tasks.md) has a mandatory gate. Present each document for review before generating the next.
  • The only exception is /build task execution. Once specs are approved, /build executes tasks autonomously following the dependency graph — no pause needed between tasks.

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.
