autospec: Instructions file for Codex

AGENTS.md

autospec AGENTS.md is an instructions file for Codex, OpenCode from ariel-frischer/autospec. It costs 3,173 tokens per session, scanned A, original, MIT.

A shorter coding-agent guide for Autospec, a Go command-line tool that helps turn a feature description into a specification, plan, task list, and implementation.

In plain words
What is it for?
Use it to build and test Autospec, run individual Go tests, format and lint code, prepare or implement features, view progress, and check dependencies.
Why use it?
It lists the required environment and everyday commands, making common build, test, formatting, linting, and workflow tasks easier to follow.

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

This is ariel-frischer/autospec's own configuration. It tells Codex and OpenCode how to work on autospec 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 autospec 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

autospec 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.

Guidance for AI coding agents working with this repository.

Prerequisites

  • Go 1.25+: Check with go version
  • AI coding agent CLI: Authenticated and configured
  • Make, golangci-lint: For build/lint (make lint)

Commands

# Build & Dev
make build          # Build for current platform
make test           # Run all tests (quiet, shows failures only)
make test-v         # Run all tests (verbose, for debugging)
make fmt            # Format Go code (run before committing)
make lint           # Run all linters

# Single test
go test -run TestName ./internal/package/

# CLI usage (run `autospec --help` for full reference)
autospec run -a "feature description"    # All stages: specify → plan → tasks → implement
autospec prep "feature description"      # Planning only: specify → plan → tasks
autospec implement --phases              # Each phase in separate session
autospec implement --tasks               # Each task in separate session
autospec st                              # Show status and task progress
autospec doctor                          # Check dependencies

Post-Change Polish (REQUIRED)

After significant code changes, automatically invoke the repo-local polish skill before final handoff. Use it to update changelog/docs and run the required validation targets. Do not wait for an explicit $polish request unless the change is trivial or docs-only.

Core Workflow

Stage Dependencies (MUST follow this order)

constitution → specify → plan → tasks → implement
     ↓            ↓        ↓       ↓
constitution.yaml spec.yaml plan.yaml tasks.yaml
Stage Requires Produces
constitution .autospec/constitution.yaml
specify constitution specs/NNN-feature/spec.yaml
plan spec.yaml plan.yaml
tasks plan.yaml tasks.yaml
implement tasks.yaml code changes

Constitution is REQUIRED before any workflow stage.

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.
