agent-style (PyPI)

CLI for The Elements of Agent Style: a literature-backed English technical-prose writing ruleset for AI agents.

Install:

pip install agent-style

Basic use:

agent-style list-tools                               # show supported tools
agent-style enable claude-code                       # wire up Claude Code
agent-style enable claude-code --dry-run --json      # preview in canonical JSON
agent-style disable claude-code                      # reverse
agent-style rules                                    # print bundled RULES.md

The CLI writes to .agent-style/ in your project and safely adds a marker-wrapped reference to your existing instruction file (CLAUDE.md, AGENTS.md, .github/copilot-instructions.md, etc.). Existing content is preserved; writes are idempotent; --dry-run previews without changing any file.

Supported tools and install modes in v0.4.2:

Tool	Install mode
claude-code	import-marker (writes `@.agent-style/claude-code.md` to your CLAUDE.md)
agents-md	append-block (writes a marker block to your AGENTS.md)
copilot	append-block (writes a marker block to `.github/copilot-instructions.md`)
copilot-path	owned-file (writes `.github/instructions/agent-style.instructions.md`)
cursor	owned-file (writes `.cursor/rules/agent-style.mdc`)
anthropic-skill	owned-file (writes `.claude/skills/agent-style/SKILL.md`)
codex	print-only (writes `.agent-style/codex-system-prompt.md`; stdout = prompt)
aider	multi-file-required (writes `.agent-style/aider-conventions.md`; stderr = `.aider.conf.yml` snippet)
kiro	owned-file (writes `.kiro/steering/agent-style.md`)
style-review	skill-with-references (installs the skill and its references on supported hosts)

The full rule set lives in the canonical repository at https://github.com/yzhao062/agent-style. This PyPI package bundles RULES.md, NOTICE.md, the 9 primary adapters, the style-review skill and its references, and the tools.json registry; running agent-style rules prints the bundled RULES.md for quick review.
