This skill should be used when the user says "check claude.md size", "is my claude.md too big", "claude.md token cost", "how big is claude.md", or when triggered automatically on session start to warn about oversized claude.md files.
This skill should be used when the user asks to "show recent changes", "show forge changelog", "show changelog for <project>", "what did I add this week", "what files did I touch today", "what packages keep recurring", "what drifts from the template", "review template suggestions", "show pending forge suggestions", "sync forge templates", "apply template suggestion", or "compute back-mapping suggestions". Provides read, drift-discovery, and template back-mapping workflows that wrap the `forge-db` MCP tools (`get_changelog`, `compute_suggestions`, `apply_suggestion`).
This skill should be used when the user says "build a wiki", "maintain a wiki", "ingest docs into wiki", "query my wiki", "set up llm wiki", "wiki-based knowledge base", "stop re-reading docs every session", "persistent knowledge base", or "compress my docs into wiki pages".
This skill should be used when the user says "auto compact", "enable auto compact", "compact on context full", "automatic context compression", "prevent context limit errors", "set up auto compaction", or "context keeps hitting limit".
This skill should be used when the user says "show settings diff", "what changed in settings", "compare settings before after", "settings optimization preview", "preview settings changes", or "show me what tune-settings will change".
Use this skill when the user says "/task_brain", "break down this task", "plan this", "decompose this problem", or when a task has multiple moving parts, unclear dependencies, or high ambiguity.

| version | 1.0.0 |
Read, analyze, and rewrite claude.md (or CLAUDE.md) to reduce token cost while preserving all meaningful constraints. Target: under 300 tokens.
Check these locations in order:
./CLAUDE.md (project root)./claude.md~/.claude/CLAUDE.md (global)~/.claude/claude.mdRead the file. Count approximate word count.
Categorize each section:
| Category | Keep? | Action |
|---|---|---|
| Coding style rules | Yes | Compress to bullets |
| Project structure | Yes | One-line per item |
| Important constraints | Yes | Keep verbatim |
| Pleasantries / tone instructions | Maybe | Cut if not essential |
| Repeated instructions | No | Remove duplicates |
| Obvious defaults | No | Remove ("always use git" etc.) |
| Long explanations | No | Replace with one-line rule |
| Examples longer than 3 lines | No | Remove or move to references/ |
Apply these compression rules:
Target structure:
# Project: [NAME]
Stack: [tech stack, one line]
## Code Style
- [rule 1]
- [rule 2]
## Constraints
- [hard constraint 1]
- [hard constraint 2]
## Structure
- [key path 1]: [purpose]
- [key path 2]: [purpose]
Present:
BEFORE: ~[N] words (~[N*1.3] tokens)
AFTER: ~[N] words (~[N*1.3] tokens)
Reduction: [%]%
Show the optimized version. Ask user to confirm before writing.
On confirmation, overwrite the file with the optimized version.
