Cosmosmith Project Rules

skill-devnomad-byte-cosmosmith-cosmosmith-project-rules · by devnomad-byte

Generate or update project instruction files for Cosmosmith-governed projects. Use when the user wants AGENTS.md, CLAUDE.md, Cursor rules, Copilot instructions, OpenCode, Trae, or other editor/agent rules created from Cosmosmith conventions, or when they ask how agents should load and follow project rules.

About

Cosmosmith Project Rules

Purpose

Install Cosmosmith project rules into the user's repository without forcing every editor to use the same file.

Workflow

Ask which rule surfaces the user wants only if it is not clear. Default to AGENTS.md only.
If AGENTS.md is requested, create or update it from the Cosmosmith generated-project template.
If CLAUDE.md is requested, create a small adapter that points to AGENTS.md as canonical.
If Cursor is requested, create .cursor/rules/cosmosmith.mdc as an adapter to AGENTS.md.
If GitHub Copilot is requested, create .github/copilot-instructions.md as an adapter to AGENTS.md.
If OpenCode is requested, create .opencode/AGENTS.md as an adapter to AGENTS.md.
If Trae is requested, create .trae/rules/cosmosmith.md as an adapter to AGENTS.md.
Keep adapters short and do not duplicate the whole constitution unless the tool requires it.
Update task.md with any follow-up tasks.

Rules

AGENTS.md is canonical for cross-agent project behavior.
Tool-specific files are adapters.
Supported adapters include CLAUDE.md, .cursor/rules/cosmosmith.mdc, .github/copilot-instructions.md, .opencode/AGENTS.md, and .trae/rules/cosmosmith.md.
If an adapter conflicts with AGENTS.md, follow AGENTS.md and update the adapter.
Do not overwrite substantial existing project rules without preserving user-specific guidance.

Completion

Stop when requested rule files exist, identify their canonical source, and record any follow-up tasks.
