What it does

Scoped Tests is an agent skill from coleam00/helpline. Use after changing code, before claiming work is done — run the test command scoped to what you changed instead of the whole suite, to avoid the timeout and context waste of full-suite runs on a small change.

Its SKILL.md is about 290 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows. The repository describes itself as: Demonstration codebase for building the AI Layer (CLAUDE.md hierarchy, hooks, skills, LSP, MCP, plugin) — companion repo for the 'How Claude Code works in large codebases' video.

When your agent uses it

  • Agent Workflows work in your project

Example prompts

  • “/scoped-tests”

Workflow steps

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

  1. Changed one service / package / app? Run only that area's test command.
  2. Changed shared / core code that other areas import? Run the full suite —
  3. Not sure what a change reaches? Trace its importers first (the

What it can do on your machine

Read from SKILL.md and the folder at commit 456234a. 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

Scoped Tests loads about 288 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 135 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~288

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 135 words (~288 tokens).

“The article's rule: running the full suite when you changed one part of the codebase wastes context and time. Pick the narrowest command that still covers the change.”
