aix AGENTS.md

A codebase guide for aix, a Go command-line tool that manages AI coding-assistant settings across several tools.

In plain words
What is it for?
It helps developers compile the tool, run all or selected tests, check for data races, measure test coverage, format Go code, and run static checks.
Why use it?
It records the commands and coding conventions needed to build, test, format, lint, and inspect the project safely.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

aix 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 2d 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.

Agent Instructions for aix

aix is a unified Go CLI for managing AI coding assistant configurations across platforms (Claude Code, OpenCode, Codex, Gemini CLI). See docs/adr/001-unified-agent-cli.md for full architecture.

Development Commands

Build

go build ./cmd/aix                      # Build CLI binary
go build ./...                          # Build all packages

Test

go test ./...                           # All tests
go test ./internal/skill/...            # Single package
go test -run TestSkillParser ./...      # Single test by name
go test -v -run TestSkillParser/valid ./...  # Subtest by name
go test -race ./...                     # With race detection
go test -cover ./...                    # With coverage
go test -coverprofile=coverage.out ./... && go tool cover -html=coverage.out

Lint & Format

go fmt ./...                            # Format code
goimports -w .                          # Organize imports
go vet ./...                            # Static analysis

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.
