After fixing an artifact in one LEAPP core, find and fix the same defect in the sibling cores.

  • Works in 5 steps: Update every checkout first → Find the twins → Read each twin before touching it → …
  • A fix has just landed
  • SKILL.md covers 1. Update every checkout first, 2. Find the twins, 3. Read each twin before… and 4. Fix each one on its own…, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Leapp Sweep Siblings is an agent skill from abrignoni/VLEAPP. After fixing an artifact in one LEAPP core, find and fix the same defect in the sibling cores. Use when a fix has just landed or is about to, when asked to "level" a change across cores, or when checking whether a defect found in one tool exists in the others.

Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Vehicle Logs Events And Properties Parser. The licence is MIT.

When your agent uses it

  • A fix has just landed
  • Asked to level a change across cores
  • Checking whether a defect found in one tool exists in the others

Example prompts

  • “/leapp-sweep-siblings”

Workflow steps

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

  1. Update every checkout first
  2. Find the twins
  3. Read each twin before touching it
  4. Fix each one on its own branch and PR
  5. Verify per core, not once

What it can do on your machine

Read from SKILL.md and the folder at commit 87b2f9c. 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

Leapp Sweep Siblings loads about 695 tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 391 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~695

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.

Sweeping sibling cores after a fix

iLEAPP, ALEAPP, RLEAPP, VLEAPP and DLEAPP carry independent copies of many artifacts. A fix in one does not reach the others, and the stale copy keeps shipping the defect to examiners.

1. Update every checkout first

A local clone that is days behind will tell you a fix is missing when it already shipped, or that a file is clean when it is not. Fetch before you look, or query the remotes directly.

2. Find the twins

Grep each sibling for the artifact filename and for the app's package or bundle identifier. The filename alone misses copies that were renamed, and the identifier alone misses modules that handle several apps.

The leapp-cross-core rule lists app names already known to exist in more than one core. Treat it as a starting point, not the full set.

3. Read each twin before touching it

The copies drift. Expect the same defect at different line numbers, and expect extra defects the original never had. Do not apply the patch blind.

Check the reverse direction too. A defect you found in one core may exist unfixed in the one you think of as canonical.

Show full SKILL.md (195 more words)Show less

4. Fix each one on its own branch and PR

One PR per repo. Each core has its own CI, its own lint debt and its own reviewers.

Apply the "Needs Cross Core Leveling" label when a change should propagate but you are not doing all of them now. Do the grep yourself rather than trusting the label to be actioned later.

5. Verify per core, not once

Row counts differ between cores because the underlying app data differs. Confirm each fix against data for that platform. A count that matches the other core is a coincidence worth questioning, not a confirmation.

Shared infrastructure counts too

The same drift applies to scripts/lavafuncs.py, scripts/html_safe.py, scripts/ilapfuncs.py and the admin/ checkers, which are meant to stay in step across cores. When porting one of those, verify the helper you are copying into is not older than the one you copied from, and check the helper itself rather than just the number of findings a checker reports. A stale helper can make a checker report zero while the defect is still live.

leapps-org/leapps-parity scans for exactly this class of drift and its report is a reasonable place to start.
