gwm-cli AGENTS.md

Project instructions that require test-driven development (TDD): write a failing test, add the smallest code change that passes it, then clean up. They define which changes need tests and where those tests belong.

In plain words
What is it for?
Use them when changing the gwm-cli project, especially for new commands, flags, output formats, bug fixes, and other externally visible behavior.
Why use it?
They give AI coding assistants clear contribution rules and prevent new behavior from being added without a test proving it works.

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

gwm-cli 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 yesterday.

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.

gwm-cli — house rules for AI assistants

This file is the project-level AGENTS.md. Anything stated here OVERRIDES defaults and applies to every contribution made via an AI assistant in this repository.

🔴 Primordial rule — Test-Driven Development is mandatory

No production code lands without a failing test that pinned the behaviour down first. This is not a guideline, it is a hard merge requirement. PRs that add or change behaviour without tests are sent back, full stop.

The TDD loop (red → green → refactor)

  1. Red — write a failing test that captures the new behaviour or the bug you are fixing. Run it. It MUST fail for the right reason (assertion mismatch, not a compile error in unrelated code). Commit the test alone if it helps reviewers see the contract.
  2. Green — write the minimum production code to make the test pass. No extra branches, no speculative abstractions.
  3. Refactor — clean up while the tests are green. Re-run the full suite after every refactor step.

What counts as "behaviour"

Anything observable from outside the function under test:

  • A new CLI subcommand, flag, or output format → end-to-end test in tests/cli_binary.rs via assert_cmd.
  • A new public function in src/<module>.rs → unit test in tests/<module>_tests.rs.
  • A new bootstrap step (file copy, guard, no-symlink, command hook) → integration test in tests/bootstrap_tests.rs exercising it against a tempfile::TempDir.
  • A libgit2 worktree operation → integration test in tests/worktree_integration.rs using tests/common::init_repo().
  • A TUI state transition → state-machine test in tests/tui_app_tests.rs (ratatui-free).

Exceptions (narrow, must be argued in the PR description)

The bar to skip a test is "the change is observably untestable from the public surface". Concretely:

  • Pure formatting / typo fixes in user-facing strings → no test required if the string is incidental (a log line, a help blurb). If the string is asserted somewhere, update the assertion.
  • Dependency bumps without behaviour change → CI green is the test.
  • Comments-only changes → no test required.

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.
