What it does

Trellis Spec Bootstarp is an agent skill from anjiemo/SunnyBeach. Bootstrap project-specific Trellis coding specs with a platform-neutral single-agent workflow. Use when creating or refreshing .trellis/spec guidelines, analyzing a codebase with GitNexus, ABCoder, or source inspection, decomposing package/layer spec work, and writing real codebase-backed spec docs without placeholder text.

Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/mcp-setup.md`, `references/repository-analysis.md` and `references/spec-task-planning.md`).

It sits in Development, covering Project scaffolding. It works with Model Context Protocol. The repository describes itself as: 这是一款基于 Kotlin、MVVM 和 Jetpack 构建的【阳光沙滩】社区开源Android客户端。我们的使命是让编程学习更简单，欢迎贡献！. The licence is Apache-2.0.

When your agent uses it

  • Refreshing .trellis/spec guidelines
  • Analyzing a codebase with GitNexus
  • Source inspection
  • Decomposing package/layer spec work

Example prompts

  • “/trellis-spec-bootstarp”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Confirm Trellis is initialized and inspect the current .trellis/spec/ tree.
  2. Analyze the repository architecture with the best available tools: GitNexus, ABCoder, language
  3. Decompose the spec work by package and layer only when that reflects the actual codebase.
  4. Fill or reshape the spec files with concrete patterns, file paths, examples, and anti-patterns
  5. Verify that the final specs are internally consistent and contain no template placeholders.

What it can do on your machine

Read from SKILL.md and the folder at commit ec2bf56. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Trellis Spec Bootstarp loads about 740 tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 87 tokens; SKILL.md has 290 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~740
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Bootstrap project-specific Trellis coding specs with a platform-neutral single-agent workflow. Use when creating or refreshing .trellis/spec guidelines, analyzing a codebase with GitNexus, ABCoder, or source inspection, decomposing package/layer spec work, and writing real codebase-backed spec docs without placeholder text.

Trellis Spec Bootstarp

Use this skill to create or refresh .trellis/spec/ guidelines from the real codebase. One capable agent owns the full loop: analyze the repository, choose the spec boundaries, write the docs, and verify the result. The workflow does not depend on a specific host, CLI, or agent brand.

Workflow

  1. Confirm Trellis is initialized and inspect the current .trellis/spec/ tree.
  2. Analyze the repository architecture with the best available tools: GitNexus, ABCoder, language tooling, and direct source reads.
  3. Decompose the spec work by package and layer only when that reflects the actual codebase.
  4. Fill or reshape the spec files with concrete patterns, file paths, examples, and anti-patterns from the project.
  5. Verify that the final specs are internally consistent and contain no template placeholders.

Spec work decomposition and task planningreferences/spec-task-planning.md

GitNexus and ABCoder MCP setupreferences/mcp-setup.md

Operating Rules

  • Treat templates as starting points, not contracts. Delete, rename, split, or add spec files when the repository calls for it.
  • Prefer source-backed rules over generic advice. Every important recommendation should point at a real file or repeated local pattern.
  • Keep execution single-owner by default. Optional helper agents are an implementation detail, not a requirement or user-visible dependency.
  • Do not write platform-specific instructions unless the target project already standardizes on that platform.
  • Do not leave placeholder text, empty headings, or copied boilerplate in .trellis/spec/.

Done Criteria

  • .trellis/spec/ describes the project as it exists now.
  • Each relevant package or layer has practical coding guidance with real examples.
  • Non-applicable template sections are removed.
  • index.md files match the final spec file set.
  • Any required setup or analysis assumptions are documented in the relevant spec or task notes.
