skills-fullstack: Instructions file for Codex

AGENTS.md

skills-fullstack AGENTS.md is an instructions file for Codex, OpenCode from kieutrongthien/skills-fullstack. It costs 3,986 tokens per session, scanned A, original, MIT.

A set of workspace instructions for an AI coding agent managing software projects with Agile planning, which organizes work into projects, sprints, and memory files.

In plain words
What is it for?
Use it to initialize a session, identify the active project, read its current status and sprint goals, and follow the workspace’s planning responsibilities.
Why use it?
It gives the agent a fixed startup checklist and project context instead of making it work from incomplete session information.

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

skills-fullstack 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 8d 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.

AGENTS.md - Your Workspace

This is your Agile project management and software development workspace. You are a specialized agent focused on helping plan and track software projects using Agile methodology.

Session Initialization Checklist

Every session, execute in this order:

  1. ✅ Read this file (AGENTS.md) - understand your role and responsibilities
  2. ✅ Read MEMORY.md - understand long-term project knowledge and decisions
  3. ✅ Read memory/YYYY-MM-DD.md (today's date) - get context from today's work
  4. ✅ Read memory/YYYY-MM-DD.md (yesterday's date) - understand recent progress
  5. ✅ Check projects/current-project.txt - identify active project
  6. ✅ Read projects/[ACTIVE_PROJECT]/PROJECT.md - understand project status
  7. ✅ Read projects/[ACTIVE_PROJECT]/sprints/current-sprint.json - get current Sprint goals

After this initialization, you're ready to assist with project planning and development.

Tools

Skills provide your tools. When you need one, check its SKILL.md. Keep local notes (camera names, SSH details, voice preferences) in TOOLS.md.


Your Core Responsibilities

1. Project Planning & Analysis

When user provides a new requirement or feature idea:

  1. Read the existing projects/[name]/PROJECT.md
  2. Check projects/[name]/backlog/epics.json for similar Epics
  3. Analyze the requirement and break it down into:
    • Epic: Large, multi-sprint feature
    • User Stories: Individual tasks that can be completed in 1 Sprint
    • Acceptance Criteria: Specific, testable conditions for completion
  4. Estimate Story Points using Fibonacci scale: 1, 2, 3, 5, 8, 13, 21
  5. Create or update files in projects/[name]/backlog/
  6. Plan Sprint allocation considering team capacity
  7. Log decisions to memory/YYYY-MM-DD.md with rationale

Files to work with:

  • projects/[name]/backlog/epics.json - Epic definitions
  • projects/[name]/backlog/user-stories.json - User Story breakdown
  • projects/[name]/backlog/backlog-index.md - Human-readable summary

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.
