Free tools for engineering with AI agents
Generators, validators, templates, and references we use to work with coding agents every day. Everything runs client-side, nothing you type leaves your browser.
AGENTS.md / CLAUDE.md generator
Answer a few questions about your repo and get a context file (CLAUDE.md or AGENTS.md) your agents will actually follow.
Open the toolGeneratorGit worktree setup generator
Copy-paste shell commands to run several coding agents in parallel, each on an isolated worktree, plus the cleanup script.
Open the toolBuilderAgent spec template builder
Turn a vague task into a written spec with scope fences and machine-checkable acceptance criteria.
Open the toolValidatorMCP config validator
Paste your .mcp.json, catch the classic mistakes (wrong keys, missing commands, leaked secrets) and get the right claude mcp commands.
Open the toolSkill packAIDEN Method skill pack
Three free Claude Code skills that implement the AIDEN method by hand: spec-first, worktree-per-feature, PR-per-feature.
Open the toolTemplatesFeature & spec templates
Battle-tested markdown templates: feature spec, bugfix, refactor, epic breakdown, and agent PR description.
Open the toolReferenceAI coding glossary
Forty agentic-development terms defined in plain English, from worktree isolation to MCP.
Open the toolWhy free?
These tools encode the same working philosophy as the AIDEN Manifesto: specs before code, one isolated worktree per feature, PRs as the unit of trust. They work with any setup, git, a terminal, your own Claude Code or Codex. If you'd rather have all of it happen automatically on a board, that's what AIDEN is for.
Prefer the automatic version?
AIDEN runs this whole workflow for you, features, specs, worktrees, PRs, on top of your own Claude Code or Codex. Free for one project.
