# Context Anchor (CANVAS Framework)
Most GTM skills share one gap: each one re-asks who the buyer is, what the product does, and why it wins, and gets a slightly different answer every time. Context Anchor captures those answers once in a versioned file, then keeps the file honest with a freshness and completeness score so downstream skills never run on stale positioning.
## Core Principle
**One source of truth, dated and scored.** A context file nobody has touched in a quarter quietly spreads outdated positioning, because every skill downstream repeats it.
## The CANVAS Framework
| Letter | Section | The Question |
|---|---|---|
| **C** | Claim | What do we say we do better, in one sentence a buyer would repeat? |
| **A** | Audience | Who buys, who uses, who signs? (ICP firmographics + personas) |
| **N** | Need | Which job or pain triggers a purchase right now? |
| **V** | Voice | How we sound: words we use, words we never use, reading level |
| **A** | Alternatives | What else the buyer considers, including doing nothing |
| **S** | Substantiation | Which numbers, logos, and quotes back the claim? |
## Process
1. **Interview** - ask one CANVAS section at a time; accept "unknown" rather than guessing
2. **Draft** - write `GTM_CONTEXT.md` with one H2 per CANVAS section and a `last_reviewed` date per section
3. **Score completeness** - each section scores 0 (missing), 1 (asserted), or 2 (asserted + evidence); completeness = total / 12
4. **Score freshness** - per secti
