/readme-restructure — README Information Architecture

Restructure a README so the value prop and audience signal land before any internals. This skill does not rewrite content — it re-orders sections and pushes dense detail behind <details> or into separate docs.

Arguments

$ARGUMENTS

• <path-to-README.md> — the file to restructure. Defaults to README.md in the current working directory.
• --dry-run (default) — produce a structure diff and a written restructure plan; do not write.
• --apply — after approval, rewrite the file in place. The original is preserved as README.md.bak.
• --target (default: both) — optimize for human, llm, or both. Affects ordering heuristics: humans skim, LLMs read top-down.

What this solves

A README's job is to land three signals in the first 200 tokens:

1. What is this? (category noun + defining trait)
2. Who is it for? (audience)
3. How do I try it in 30 seconds? (quick-start or one-line install)

The user's mache/README.md is the motivating example. Its first 1000 chars are good — until paragraph 4:

"Seventeen MCP tools wrap the projected graph (sixteen read-surface plus write_file). Fourteen work standalone; three (semantic_search, get_type_info, get_diagnostics) require ley-line-open enrichment. find_smells covers nine structural code-smell rules (dead_code, cyclomatic_complexity, god_file, fan_out_skew, untested_function, …); four of those require a .db built by ley-line-open."

That paragraph is accurate and useful — but it requires the reader to already know what an MCP tool is, what ley-line-open enrichment is, and what "structural code-smell rules" means. A first-time reader bounces. This skill moves that paragraph behind a <details> or into a ## Tools section further down, without deleting it.

Hard rules

• Never delete content. Every paragraph from the original must appear in the output. Re-order, fold into <details>, or move to a sub-page — but don't drop.
• Never invent claims. If the README says "stable on macOS" and you can't verify, leave that claim alone. Don't add caveats it didn't have, don't drop caveats it did.
• Preserve all links. A restructure that breaks an internal anchor link is worse than the original.
• Preserve all code blocks verbatim. No editing example commands, paths, or shell snippets.
• Don't reorder ADRs, CHANGELOG, or LICENSE references — those have conventional positions.

Target structure

A well-shaped README converges to:

# <Project>

<One-sentence pitch. Category noun + defining trait. 120–200 chars.>

<Optional: tagline / pull-quote. 1 line.>

<Optional: screenshot or demo gif.>

## Quick start

<3–6 lines that get the reader from clone to first useful output.>

> For the full first-run flow, see [GETTING-STARTED.md](GETTING-STARTED.md).

## What it does

<2–4 short paragraphs. Plain language. No jargon-density.>

## How it works

<One diagram or 4–6 numbered steps. Conceptual, not exhaustive.>

## Status

<Table: capability → state (stable/beta/experimental/optional).>

<details>
<summary>Why this exists</summary>
<motivation, philosophy, design rationale>
</details>

<details>
<summary>Deeper internals</summary>
<the dense paragraphs that were frontloaded before>
</details>

## Install / deploy

<full install matrix>

## License

The principle: everything dense or jargon-rich goes below the fold or into <details>. The above-fold content is meant for a reader who knows nothing about the project.

Workflow

Phase 1: Read and section-map

Read the README and produce a section map:

Section: "# Mache" + tagline
  Lines: 1–8
  Density: low ✓
  Audience: any
  Verdict: keep front

Section: "## Quick start"
  Lines: 10–22
  Density: low ✓
  Audience: any
  Verdict: keep front

Section: "## What it gives an agent"
  Lines: 24–28
  Density: HIGH (paragraph names 17 tools, internal subsystem, optional deps)
  Audience: returning user / MCP-literate
  Verdict: MOVE BEHIND <details> or to "## Tools" section
...

For each section, score density by:

• Count of proper nouns / project-specific terms per 100 chars
• Count of inline code spans per 100 chars
• Whether it references concepts not yet introduced

Phase 2: Diagnose

Print a one-page diagnosis:

## Diagnosis: mache/README.md (144 lines)

Score: 6/10
  ✓ Title + tagline lands fast (lines 1–4)
  ✓ Quick start present and short (lines 10–22)
  ✗ Paragraph at line 24 frontloads 17-tool inventory + ley-line-open coupling
    → first-time reader bounces here
  ✓ Mermaid diagram is well-placed
  ✗ "Status" table is good but appears after dense paragraph
  ✓ <details> for "Why this exists" — good pattern
  ✗ Missing: clear "audience" signal — who is this for?

Recommended moves:
  1. Move lines 24–28 ("What it gives an agent") to a new "## Tools" section after "How it works"
  2. Insert a one-line audience signal after the tagline: "Built for agents that need to navigate code, not grep it."
  3. Promote the "Status" table to right after "How it works" — readers want stability info early

Phase 3: Restructure plan

Produce the explicit re-ordering plan as a list of moves:

Move:
  - lines 24–28 → after line 92 (new ## Tools heading)
  - lines 53–67 (Status table) → after line 33 (right after Quick start)

Wrap in <details>:
  - lines 130–140 (deployment matrix continued — too dense for above-fold)

Insert:
  - line 4 (after tagline): "Built for agents that need to navigate code, not grep it."

Phase 4: Generate proposed README

In dry-run mode, produce the proposed README content in a separate file (README.md.proposed) without touching the original. Show a unified diff for review.

Phase 5: Approval

• --dry-run (default): keep README.md.proposed and README.md.diff on disk; do not modify README.md.
• --apply: prompt "Apply this restructure? (yes/no)". On yes: copy README.md → README.md.bak, then replace with README.md.proposed.

Phase 6: Verify

After apply, run:

# Sanity check: every line from original must appear somewhere in restructured
diff <(sort README.md.bak | uniq) <(sort README.md | uniq) | grep '^<'

Report any lines that were dropped (should be zero — they're a bug).

Phase 7: Report

Applied: README.md restructured
  Before: 144 lines, value prop diluted by line 24
  After:  148 lines (3 inserts), value prop holds through line 50
  Original backed up to README.md.bak

Manual follow-ups suggested:
  - "Tools" section is now 18 lines — consider moving the full inventory to docs/TOOLS.md
  - The Status table could be a separate STATUS.md if it grows

Important rules

• Default to --dry-run. A README is the first thing every visitor reads. Don't write live.
• Preserve README.md.bak after --apply. Easy rollback.
• Show the diff, not the full file in the dry-run output. The diff is the artifact; the proposed file is on disk for inspection.
• One README per pass. Don't batch multiple repos through this skill — each README needs its own diagnosis.
• If the README scores 8+ in diagnosis, recommend skipping. Marginal restructure on a working README is churn.

Examples

/readme-restructure
→ dry-run on ./README.md

/readme-restructure <path-to-repo>/README.md
→ dry-run on that repo's README

/readme-restructure ./README.md --apply
→ dry-run, prompt, write

/readme-restructure ./README.md --target=llm
→ optimize ordering for an LLM ingesting top-down rather than a human skimming
