| description | Understand and customize the local Trellis architecture inside a user project. Use when modifying .trellis plus platform hooks, settings, agents, skills, commands, prompts, or workflows generated by trellis init. |
Trellis Meta
This skill is for local Trellis users who have already run trellis init in a project. After
reading it, an AI should understand the Trellis architecture, operating model, and customization
entry points inside that user project, then modify the generated .trellis/ and platform directory
files according to the user's request.
The default operating scope is local files in the user project:
.trellis/: workflow, config, tasks, spec, workspace, scripts, and runtime state.- Platform directories:
.claude/, .codex/, .cursor/, .opencode/, .kiro/, .gemini/,
.qoder/, .codebuddy/, .github/, .factory/, .pi/, .kilocode/, .agent/, .windsurf/,
and similar directories.
- Shared skill layer:
.agents/skills/.
Do not assume the user has the Trellis source repository. Do not default to modifying the global npm
install directory or node_modules.
How To Use
- Read
references/local-architecture/overview.md first to establish the local Trellis system
model.
- If the request involves a specific AI tool, read
references/platform-files/platform-map.md and
the relevant platform file notes.
- If the user wants to change behavior, read
references/customize-local/overview.md, then open
the specific customization topic.
- Before editing, read the actual files in the user project and treat local content as
authoritative.

Current Rules
.trellis/workflow.md is the local workflow source of truth..trellis/config.yaml is the project-level Trellis configuration and task hook configuration
entry point..trellis/spec/ stores the user's project-specific coding conventions and design constraints..trellis/tasks/ stores task PRDs, technical notes, research files, and JSONL context..trellis/workspace/ stores developer journals and cross-session memory.- Platform settings/config files decide which hooks, agents, skills, commands, prompts, and
workflows actually run.
.trellis/.template-hashes.json and .trellis/.runtime/ are management/runtime state files.
Confirm necessity before editing them.
Do Not
- Do not treat Trellis upstream source code as the default target for local customization.
- Do not modify the global npm install directory or
node_modules/@mindfoldhq/trellis to implement
project needs.
- Do not overwrite user-modified local files with default templates.
- Do not put team-private project rules into the public
trellis-meta; put project rules in
.trellis/spec/ or a project-local skill.
- Do not describe removed historical mechanisms as current Trellis behavior.
