Find duplicate functions and eliminate them so they stay gone. Triage tl dupes output by tier, apply the right consolidation pattern, and lock the win with a duplication-ratchet test. Use when asked to dedupe, remove duplication, consolidate copy-paste, clean up repeated helpers, or act on tl dupes output.
Find duplicate functions in Codex and remove them so they stay gone — triage tl dupes by tier, consolidate the second home (not both copies), and add a duplication-ratchet test to block regressions. Use when deduping, removing copy-paste, consolidating repeated helpers, or acting on tl dupes output.
Git commits, pushes, and GitHub operations using tokenlean. Covers tl push (with multi-file safety guard), tl commit-prep, tl gh (bulk issue/PR/release operations), and when to use tl gh vs gh CLI vs GitHub MCP. Use when committing, pushing, creating/closing/viewing issues, managing PRs, creating releases, or any git/GitHub workflow.

Add new functionality by understanding existing patterns and dependencies before writing code. Locates where the feature belongs, studies conventions, implements following precedent, then verifies integration. Use when asked to add a feature, flag, endpoint, component, or module.
Thorough code review using token-efficient context gathering. Analyzes PRs, diffs, or staged changes by checking blast radius, complexity, and dependencies before reviewing the actual code. Use when asked to review a PR, review changes, or do a code review.

tl structure
Identify core directories, file counts, and token estimates. Note likely runtime paths (bin/, src/, test/, config files).
tl parallel "tl entry" "tl hotspots"
For each important file:
File size → Decision
├─ <150 lines → Just read it
├─ 150-400 lines → tl symbols first, tl snippet for specifics
└─ 400+ lines → tl symbols only, then tl snippet as needed
# Per file, gather context in one call:
tl parallel "symbols=tl symbols <file>" "exports=tl exports <file>"
# Or for entire directories:
tl symbols src/ # All files in a directory (compact one-liner per file)
tl parallel \
"deps=tl deps <file>" \
"impact=tl impact <file>" \
"flow=tl flow <function> <file>"
Produce:
tl parallel to gather context on multiple files simultaneously.tl context <dir> shows token cost of a directory — skip reading dirs over 50k tokens directly.git log -- <file>) to identify active areas.
