This skill should be used when reducing the code complexity threshold of the codebase. It lowers the CyclomaticComplexity threshold by 2, identifies methods that exceed the new limit, generates a brief with refactoring strategies, and creates a plan with tasks to fix all violations.

Lower Code Complexity
Reduces the CyclomaticComplexity threshold by 2 and fixes all violations.
Step 1: Gather Requirements
- Read current threshold from
.rubocop.yml(Metrics/CyclomaticComplexityMax) - Calculate new threshold: current - 2 (e.g., 10 -> 8)
- Run RuboCop and flog to find violations:
bundle exec rubocop --only Metrics/CyclomaticComplexity,Metrics/PerceivedComplexity --format json 2>&1bundle exec flog --all --group app/ 2>&1 | head -50 - Note for each violation:
- File path and line number
- Method name
- Current complexity score (RuboCop and/or flog)
If no violations at new threshold, report success and exit.
Step 2: Compile Brief and Delegate
Compile the gathered information into a structured brief:
Reduce CyclomaticComplexity threshold from [current] to [new].
Methods exceeding threshold (ordered by complexity):
1. [file:method_name] (complexity: X, target: [new]) - Line Y
- flog score: Z
2. ...
Configuration change: .rubocop.local.yml, Metrics/CyclomaticComplexity Max from [current] to [new]
Refactoring strategies: extract methods, early returns, extract conditions, use lookup hashes, replace conditionals with polymorphism
Verification: `bundle exec rubocop --only Metrics/CyclomaticComplexity --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.
