This skill should be used when reducing the maximum lines per method threshold and fixing all violations. It updates the RuboCop configuration, identifies methods exceeding the new limit, generates a brief with refactoring strategies, and creates a plan with tasks to split oversized methods.

Reduce Max Lines Per Method
Target threshold: $ARGUMENTS lines per method
If no argument provided, prompt the user for a target.
Step 1: Gather Requirements
- Read current config from
.rubocop.ymlor.rubocop.local.yml(Metrics/MethodLength) - Run RuboCop with the target threshold to find violations:
bundle exec rubocop --only Metrics/MethodLength --format json 2>&1 - Note for each violation:
- File path and line number
- Method name
- Current line count
If no violations at $ARGUMENTS, report success and exit.
Step 2: Compile Brief and Delegate
Compile the gathered information into a structured brief:
Reduce max lines per method threshold to $ARGUMENTS.
Methods exceeding threshold (ordered by line count):
1. [file:method_name] (lines: X, target: $ARGUMENTS) - Line Y
2. ...
Configuration change: .rubocop.local.yml, Metrics/MethodLength Max to $ARGUMENTS
Refactoring strategies: extract methods, early returns, extract conditions, use lookup hashes, consolidate logic
Verification: `bundle exec rubocop --only Metrics/MethodLength --format simple 2>&1 | grep "offense" | wc -l` -> Expected: 0
Invoke /implement with this brief to create the implementation plan.

codyswanngt/lisa-wiki-onboard-me
documentation
VerifiedTrustedCommunity
Onboard a user to the project via its LLM Wiki. Interviews the user about themselves in relation to the project, captures that to project-scoped memory only, then gives a guided tour of what the project is and sample questions they can ask. Use when someone is new to the project or asks to be onboarded. Read-mostly — it does not open PRs or write PII into the wiki.

codyswanngt/lisa-wiki-migrate
documentation
VerifiedTrustedCommunity
Migrate an existing, hand-rolled wiki implementation onto the lisa-wiki kernel — phased and compatibility-first, with a strict no-loss guarantee. Use when adopting lisa-wiki in a repo that already has its own wiki/, ingest skills, docs, or roles. Renaming things into the canonical shape is fine; losing functionality or data is not. Ends by running /doctor.

codyswanngt/lisa-wiki-lint
development
VerifiedTrustedCommunity
Health-check the LLM Wiki. Reports orphan pages, contradictions, stale claims, broken internal links, missing index/log coverage, structure-manifest violations, and secret/tenant leaks. Use periodically or before hardening a wiki. Read-only — it reports findings, it does not fix them.

codyswanngt/lisa-wiki-ingest
testing
VerifiedTrustedCommunity
Ingest source material into the LLM Wiki. With an argument (URL, file path, or prompt) it ingests that one source; with no argument it runs a full ingest across every enabled non-external-write source. Routes to the right connector, then runs the ordered pipeline (source note → synthesis → index → log → verify → state → commit/PR). Use whenever new knowledge should enter the wiki.
