tagit: Instructions file for Codex

AGENTS.md

tagit AGENTS.md is an instructions file for Codex, OpenCode from liliang-cn/tagit. It costs 602 tokens per session, scanned A, original, MIT.

Repository instructions for a Go project whose design and implementation contracts are documented before executable code is added.

In plain words
What is it for?
Bootstrapping the project, organizing Go packages, validating builds and tests, and implementing the documented domain, event, storage, runtime, and scheduling modules.
Why use it?
They explain the planned module boundaries, build and test commands, naming rules, and documentation that future code must follow.

Written for Codex and OpenCode: the file is AGENTS.md.

This is liliang-cn/tagit's own configuration. It tells Codex and OpenCode how to work on tagit 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 tagit 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

tagit 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.

Repository Guidelines

Project Structure & Module Organization

This repository is currently design-first. The top-level architecture and system constraints live in DESIGN.md. Detailed implementation contracts are under docs/:

When code is added, keep Go packages under internal/ with module-aligned directories such as internal/domain, internal/events, internal/store, internal/runtime, and internal/scheduler.

Build, Test, and Development Commands

The repository does not yet contain executable code. Once bootstrapped, prefer these commands:

go test ./...
go test ./internal/...
go build ./...

Use go test ./... for full validation, go test ./internal/... for package-scoped iteration, and go build ./... to catch interface and wiring regressions.

Coding Style & Naming Conventions

Write Go in standard gofmt style with tabs for indentation. Keep package names short and lowercase: store, policy, runtime. Exported types use PascalCase; unexported helpers use camelCase. Interface names should reflect capability, such as EventStore, Supervisor, or Broker.

Name documents and specs in kebab-case, for example domain-schema-spec.md. Keep terminology aligned with the existing specs: ArtifactEnvelope, ExecutionPlan, FailedRecoverable.

Testing Guidelines

Use Go’s built-in testing package. Prefer table-driven tests for domain validation, policy rules, and state transitions. Name files *_test.go and test functions TestXxx. Add focused unit tests for pure logic first, then integration tests for PTY, worktree, and persistence boundaries.

Changes

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.
