test:evals requires ANTHROPICAPIKEY. Codex E2E tests (test/codex-e2e.test.ts, test/codex-e2e-sol-scope.test.ts) use Codex's own auth — the hermetic runner copies only auth.json from ${CODEXHOME:-~/.codex} and pins CODEXHOME in the child env — no OPENAIAPIKEY env var needed. Hermetic E2E + env keys: every E2E runner spawns children through test/helpers/hermetic-env.ts (allowlist-scrubbed env, fresh seeded CLAUDECONFIGDIR, temp GSTACKHOME, --strict-mcp-config); per-test env: overrides merge last onto a COMPLETE hermetic env, so they're safe. A PTY test that types a /skill command must pass seedSkills: true. Debug…
Design consultation: understands your product, researches the landscape, proposes a complete design system (aesthetic, typography, color, layout, spacing, motion), and generates font+color preview... (gstack)

gstack is Garry's Stack: AI coding skills + a fast headless browser binary + a design CLI. This file indexes every capability so agents can discover and invoke them without crawling individual SKILL.md files. Conventions: - Skills are invoked by name (e.g. /ship, /plan-ceo-review). - Browse commands run as browse <command> [args] (or $B shorthand). - Design commands run as design <command> [args] (or $D). - Project-specific config lives in CLAUDE.md. Always read it first.
Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.
CLAUDE.md or AGENTS.md?
CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.
What is a skill?
A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.
Can I search my own team's files too?
Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
