fista-spec-kit: Instructions file for Claude Code

AGENTS.md

fista-spec-kit AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from fistasolutions/fista-spec-kit. It costs 3,305 tokens per session, scanned A, a copy of spec-kit-zh AGENTS.md, MIT.

Repository instructions for Fista Spec Kit, a toolkit for Spec-Driven Development. This approach writes a clear software specification before implementation and uses templates and workflows to guide the work.

In plain words
What is it for?
Use it when changing the Specify command-line tool, updating agent integrations, or following the project's specification-first development process.
Why use it?
It explains the project's development rules and how to add support for different AI coding assistants without breaking the shared workflow.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: $ARGUMENTS substitution, but also the file is AGENTS.md. Also seen: reads .claude/ paths; mentions Claude Code; mentions AGENTS.md.

This is fistasolutions/fista-spec-kit's own configuration. It tells Claude Code, Codex and OpenCode how to work on fista-spec-kit 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 fista-spec-kit 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

fista-spec-kit 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 2mo 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.

Origin

About Spec Kit and Specify

GitHub Spec Kit is a comprehensive toolkit for implementing Spec-Driven Development (SDD) - a methodology that emphasizes creating clear specifications before implementation. The toolkit includes templates, scripts, and workflows that guide development teams through a structured approach to building software.

Specify CLI is the command-line interface that bootstraps projects with the Spec Kit framework. It sets up the necessary directory structures, templates, and AI agent integrations to support the Spec-Driven Development workflow.

The toolkit supports multiple AI coding assistants, allowing teams to use their preferred tools while maintaining consistent project structure and development practices.


General practices

  • Any changes to __init__.py for the Specify CLI require a version rev in pyproject.toml and addition of entries to CHANGELOG.md.

Adding New Agent Support

This section explains how to add support for new AI agents/assistants to the Specify CLI. Use this guide as a reference when integrating new AI tools into the Spec-Driven Development workflow.

Overview

Specify supports multiple AI agents by generating agent-specific command files and directory structures when initializing projects. Each agent has its own conventions for:

  • Command file formats (Markdown, TOML, etc.)
  • Directory structures (.claude/commands/, .windsurf/workflows/, etc.)
  • Command invocation patterns (slash commands, CLI tools, etc.)
  • Argument passing conventions ($ARGUMENTS, {{args}}, etc.)

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.
