speckit: Instructions file for Codex

AGENTS.md

speckit AGENTS.md is an instructions file for Codex, OpenCode from jmanhype/speckit. It costs 4,083 tokens per session, scanned A, original, MIT.

Repository instructions for Spec Kit and Beads, tools for structured specifications and a persistent task graph. They describe user stories, priorities, acceptance criteria, and test-driven development, or TDD, where tests guide implementation.

In plain words
What is it for?
Use them to turn specifications into tasks, track task states, define acceptance criteria, and enforce tests during development.
Why use it?
They give coding agents a shared way to plan work, track dependencies, and verify changes across sessions.

Instructions file for CodexOpenCode

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

This is jmanhype/speckit's own configuration. It tells Codex and OpenCode how to work on speckit 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 speckit 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

speckit 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.

AGENTS.md - Instructions for AI Coding Agents

This file contains workflow rules and guidelines for AI agents (Claude Code, GitHub Copilot, Cursor, Amp, etc.) working in repositories that use Spec Kit + Beads.

Core Philosophy

Spec Kit provides structure (WHAT/WHY/HOW). Beads provides memory (persistent task graph that survives context limits).

Together they solve:

  • ✅ Structured specification-driven development
  • ✅ Long-term memory across sessions
  • ✅ Dependency tracking that doesn't disappear
  • ✅ Work discovery and prioritization

Pivotal Methodology Alignment

Spec Kit + Beads implements practices from Pivotal Labs (now VMware Tanzu Labs):

Pivotal Practice Spec Kit + Beads Implementation
TDD test-gate.sh enforces 100% test pass after every edit
User Stories spec.md with P1/P2/P3 priorities, [US#] references
Story Types Beads: --type epic/task/bug, labels for chores
Story States Beads: --status todo/in-progress/done/blocked
Acceptance Criteria spec.md ## Acceptance Criteria → Beads epic description
IPM (Planning) /speckit.specify → /speckit.plan → /speckit.tasks
Velocity Beads tracks task completion; bd ready shows unblocked work
Dependencies bd dep add creates blocking relationships (P0 → P1 → P2)

Pivotal-Style Epic Format

Beads epics created by Spec Kit include:

PROBLEM STATEMENT:
[From spec.md ## Problem Statement]

BUSINESS VALUE:
[From spec.md ## Business Value]

ARCHITECTURAL VISION:
[From plan.md ## Architectural Vision]

INTEGRATION TESTS:
[From spec.md ## Integration Tests]

Acceptance Criteria:
[From spec.md ## Acceptance Criteria]

Blocks (N):
  ← TASK-1: P0 task description
  ← TASK-2: P1 task description
  ...

Priority Levels (Pivotal-Aligned)

Priority Pivotal Equivalent Description
P0 Urgent/Blocker Critical path, blocks everything else
P1 High MVP features, must-have
P2 Medium Should-have, important but not blocking
P3 Low Nice-to-have, future enhancements

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.
