TLDR

Ultra-compressed commit message generator. Cuts noise from commit messages while preserving intent and reasoning. Conventional Commits format. Subject ≤50 chars, body only when "why" isn't obvious. Use when user says "write a commit", "commit message", "generate commit", "/commit", or invokes /tldr-commit. Auto-triggers when staging changes.

Compress natural language memory files (CLAUDE.md, todos, preferences) into TLDR format to save input tokens. Preserves all technical substance, code, URLs, and structure. Compressed version overwrites the original file. Human-readable backup saved as FILE.original.md. Trigger: /tldr-compress FILEPATH or "compress memory file"

Quick-reference card for all tldr modes, skills, and commands. One-shot display, not a persistent mode. Trigger: /tldr-help, "tldr help", "what TLDR commands", "how do I use TLDR".

Ultra-compressed code review comments. Cuts noise from PR feedback while preserving the actionable signal. Each comment is one line: location, problem, fix. Use when user says "review this PR", "code review", "review the diff", "/review", or invokes /tldr-review. Auto-triggers when reviewing pull requests.

Verdict-first communication mode. Cuts token usage 60-75% by enforcing TLDR rules (1-sentence default, 3-word target, shape dispatch) while preserving full technical accuracy and truth priority. Supports levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "tldr mode", "talk TLDR", "verdict first", "no filler", or invokes /tldr. Auto-triggers on token efficiency or when TLDR style is requested.

Show real token usage and estimated savings for the current session. Reads directly from the Claude Code session log — no AI estimation. Triggers on /tldr-stats. Output is injected by the mode-tracker hook; the model itself does not compute the numbers.

Update TLDR from GitHub and refresh installed agent hooks, skills, MCP, and rules. Triggers on /tldr-update, "tldr update", "update TLDR", or when the user asks to upgrade the TLDR install. Run via Bash: `tldr update` or `node <repo>/bin/install.js update`.

Decision guide for delegating to tldr-style subagents. Tells the main thread WHEN to spawn `tldrcrew-investigator` (locate code), `tldrcrew-builder` (1-2 file edit), or `tldrcrew-reviewer` (diff review) instead of doing the work inline or using vanilla `Explore`. Subagent output is tldr-compressed so the tool-result injected back into main context is ~60% smaller — main context lasts longer across long sessions. Trigger: "delegate to subagent", "use tldrcrew", "spawn investigator/builder/reviewer", "save context", "compressed agent output".
