What it does

Regression Check is an agent skill from haru/redmine_ai_helper. Run the full regression suite for the redmineaihelper plugin (YARD doc coverage, RuboCop, and the plugin test suite) via .devcontainer/regression-check.sh

Its SKILL.md is about 490 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 Testing & QA, covering Test generation. The repository describes itself as: A Redmine plugin that adds AI agents, MCP Server, smart completion, and vector search. The licence is MIT.

When your agent uses it

  • Tasks that involve Test generation

Example prompts

  • “/regression-check”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Run the regression script
  2. Triage failures
  3. Re-run until clean

What it can do on your machine

Read from SKILL.md and the folder at commit 3cd87d6. 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

    Shell commands in SKILL.md call:

    • sh
    • bundle

    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

Regression Check loads about 492 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 228 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~492

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.

description
Run the full regression suite for the redmine_ai_helper plugin (YARD doc coverage, RuboCop, and the plugin test suite) via .devcontainer/regression-check.sh

Regression Check

Run the plugin's full regression check: YARD documentation coverage, RuboCop linting, and the complete Minitest suite.

Workflow

Step 1: Run the regression script
bash
sh -x .devcontainer/regression-check.sh

The script (.devcontainer/regression-check.sh) does the following, in order, aborting on the first failure (set -ex):

  1. cd into the plugin root
  2. yard stats --list-undoc | tee /dev/stderr | grep -q "100.00%" — fails if documentation coverage drops below 100%
  3. rubocop — fails on any offense
  4. cd /usr/local/redmine then bundle exec rake redmine:plugins:test — runs the full Redmine test suite (all plugins, not just NAME=redmine_ai_helper)
Step 2: Triage failures
  • YARD gap: find the newly undocumented module/class/method/constant/attribute and add a doc comment.
  • RuboCop offense: fix per the rubocop skill's guidelines (see .claude/skills/rubocop/SKILL.md); never relax .rubocop.yml thresholds without explicit user approval.
  • Test failure/error: investigate the failing test, fix the underlying code (never disable or delete the test to make it pass), then re-run.
Step 3: Re-run until clean

Re-run the script after each fix until it exits 0 with:

  • 100.00% documented
  • no offenses detected
  • 0 failures, 0 errors, 0 skips

Notes

  • Must be run from a shell that can cd into /usr/local/redmine — the script assumes the plugin lives at /usr/local/redmine/plugins/redmine_ai_helper.
  • This runs the entire Redmine test suite (all plugins), which takes noticeably longer than rake redmine:plugins:test NAME=redmine_ai_helper. Use the narrower NAME= form for quick iteration while fixing a single test, and this skill for the final full check.
