In this controlled same-task single run, enabling write-guide changed the output from 2870 non-whitespace characters and 13 headings to 3743 characters and 5 headings. Matches among 8 signals extracted from the pinned source changed from 1 to 3. Both actual outputs are shown; this is a structural observation, not a quality score or a universal performance claim.

Use the write-guide Skill pinned at e2fb664ceb12 for my task. Follow its source-specific constraints around `write-guide`, `writing`, `guides`, `structure`, then return the finished deliverable with explicit assumptions, verification, failure conditions, and limits. Do not treat the Skill text as a factual source or claim that a single demonstration proves universal performance.

Pinned source
Produce a technical guide that teaches a real-world use case through progressive examples. Concepts are introduced only when the reader needs them.
Each guide solves one specific problem. Not a category of problems. If the outline has 5+ steps or covers multiple approaches, split it.
Every guide follows this arc: introduction, example setup, 2-5 progressive steps, next steps.
Each step follows this loop: working code → new requirement → friction → explanation → resolution → observable proof.
Sections: introduction (no heading, 2 paragraphs max), ## Example (what we're building + source link), ### Step N (action-oriented titles, 2-4 steps), ## Next steps (summary + related links).
Headings should tell a story on their own. If readers only saw the headings, they'd understand the guide's takeaway.
---
title: {Action-oriented, e.g., "Building X" or "How to Y"}
description: {One sentence}
nav_title: {Short title for navigation}
---
{What the reader will accomplish and why it matters. The friction and how this approach resolves it. 2 paragraphs max.}
## Example
As an example, we'll build {what we're building}.
We'll start with {step 1}, then {step 2}, and {step 3}.
{Source code link.}
### Step 1: {Action-oriented title}
{Brief context, 1-2 sentences.}
```tsx filename="path/to/file.tsx"
// Minimal working code
```
{Explain what happens.}
{Introduce friction: warning, limitation, or constraint.}
{Resolution: explain the choice, apply the fix.}
{Verify the fix with observable proof.}
### Step 2: {Action-oriented title}
{Same pattern: context → code → explain → friction → resolution → proof.}
### Step 3: {Action-oriented title}
{Same pattern.}
## Next steps
You now know how to {summary}.
