Aron PrinsandClaude Opus 5 325c9eb819 seo: hand-write titles and descriptions for all 192 pages (#115)
## Why

The build derived `<title>` from the **sidebar label** and the
description from the **first paragraph clipped to 220 characters**. Both
are the wrong source. A sidebar label is written for a 240px-wide nav
that supplies its own context; a search result has none.

On production that produced:

- **7 pages titled "Overview"**, and 32 pages sharing a title with
another page
- **109 of 193 descriptions cut off mid-word**, and 174 over 160
characters (where Google truncates)

```
/guides/welcome/key-concepts/
  BEFORE (220):  ...and if you misunderstand them early, the product wi
```

Near-identical titles are the weak-differentiation signal behind
"crawled — currently not indexed", which is the exact symptom on this
property.

## What changed

`seo_title` and `seo_description` frontmatter on **every one of the 192
pages**, written by hand against each page's real content and optimised
for the click — lead with what the reader can do, name the concrete
things covered, no keyword stuffing, no repeating the title.

| | Before | After |
|---|---|---|
| Duplicate titles | 32 pages | **0** |
| Duplicate descriptions | — | **0** |
| Descriptions cut mid-word | 109 | **0** |
| Descriptions over 160 chars | 174 | **0** |
| Title length (incl. suffix) | up to "Overview" | **26–60** |
| Description length | 31–240 | **122–158** |

**No prose was rewritten.** I measured content overlap between the
colliding pairs first — only 17–23%, so these were always distinct pages
wearing the same label, not duplicate content. The `docs/` diff is **564
insertions, zero deletions**.

### Examples

```
BEFORE — all seven identical:  "Overview | Paperclip Docs"
AFTER:  "Adapters Overview"      "API Overview"        "CLI Overview"
        "Deployment Overview"    "Bundled Skills"      "Optional Skills"
        "Experimental Features"

BEFORE — both identical:  "Issues | Paperclip Docs"
AFTER:  "Issues: Creating and Tracking Work"   /guides/day-to-day/issues/
        "Issues API"                           /reference/api/issues/
```

```
/guides/getting-started/five-minute-path/
BEFORE (220):  The shortest route from a running Paperclip instance to an agent that has
               just completed work for you. After Paperclip is installed, the path takes
               about 5 minutes: create a company, hire a CEO agent, approve its first s
AFTER  (131):  Install Paperclip, create a company, hire a CEO agent, and approve its
               first strategy — a working AI company in about five minutes.
```

## Plumbing

- **`site/build-release.mjs`** prefers the authored fields; the derived
path stays only as a fallback the CI gate prevents ever reaching.
`<title>`, `<meta name="description">`, and the `TechArticle` JSON-LD
all read from the same source.
- **`site/app.js`** uses the same fields, so a client-side transition
cannot leave a different title on screen than the crawler was served.
Verified in-browser: navigating `/guides/day-to-day/issues/` →
`/reference/api/issues/` swaps to exactly the server-rendered values, no
JS errors.
- **`scripts/verify-seo-metadata.mjs`** (new) enforces presence,
uniqueness, length, complete-sentence endings, and the
frontmatter-safety rules. Wired into `docs:test` and CI as its own step.

I negative-tested the gate rather than assuming it works — it correctly
fails on a duplicate title, a mid-word description, and a missing field,
and passes again once restored.

## Automating it going forward

`skills/sync-docs/SKILL.md` now:

- gains an **"Authored SEO metadata"** section: why the fields exist,
the enforced rules as a table, and how to actually write them (title
names the subject not the nav position; description writes for the
click; never generate mechanically from the first paragraph — *that is
the fallback the gate exists to prevent*).
- requires both fields in the **page-authoring instruction** given to
every subagent, with guidance on when to update an existing description
versus leave it.
- runs `docs:test:seo-metadata` and `docs:test:crawlable-links` as
**fail-loud gates in Phase 7** before commit.
- documents all six build gates in the files/gates section.

So once this lands, a new page cannot ship without hand-written
metadata, and a title collision cannot reach production.

## Verified

All six verifiers pass:

```
Static route verification passed
Asset fingerprint verification passed
Hierarchical Skills nav verification passed
Skill source block verification passed (11 skill pages, 1 control page)
Crawlable-link contract passed: 40886 internal links across 194 pages resolve in one hop
Authored-SEO contract passed: 192 pages carry a unique, hand-written seo_title and seo_description
```

External Objects

Issues constantly reference work that lives somewhere else — a GitHub pull request, a ticket in another tracker, a deployment. Normally those are dead links: to know whether that PR merged, you leave Paperclip and go look.

With External Objects on, Paperclip detects external URLs anywhere in an issue — title, description, comments, documents — and renders them as live status pills instead of plain links. A referenced GitHub pull request shows up as Open, Draft, Merged, or Closed right where it's mentioned, plus in a rollup panel on the issue.

External object status on an issue

Turn it on

  1. Go to Settings → Instance settings → Experimental.
  2. Turn on Enable External Objects — "Detect external URLs in issues and show resolved status for pull requests, tickets, and other referenced work objects."

Using it

There's nothing to configure per issue — just paste URLs where you'd naturally write them:

  • Detection. Whenever an issue, comment, or document is created or updated, Paperclip extracts its URLs. GitHub pull-request and issue URLs (github.com/{owner}/{repo}/pull/{n} or /issues/{n}) are recognized as first-class work objects out of the box; anything else becomes a generic link object. Plugins can register additional detectors for other systems.
  • Status pills. Recognized references render inline as a pill with a provider icon, the object (e.g. owner/repo#123), and its state — with a distinct look for merged PRs, an ×N counter when the same object is referenced several times, and a dashed border when the status is stale, unreachable, or needs authentication. A newly detected object starts as "Not yet refreshed" until it's resolved.
  • The External objects panel. The issue's Related Work area gains an External objects section — "Remote work referenced from this issue — pull requests, deployments, tickets in other systems, and more." — listing every detected object with its status and where it was mentioned, sorted severity-first.
  • Lists and sidebar. Issue list rows get a compact status badge and the list toolbar gains an external-object status filter; project rows in the sidebar roll up the dominant status.

GitHub access

Public repositories resolve without setup. For private repos (and friendlier rate limits), add a company secret named GITHUB_TOKEN, GH_TOKEN, or PAPERCLIP_GITHUB_TOKEN. Without access, private objects show "Requires auth".

When it's off

Hidden and inert: detection stops, pills fall back to plain links, the panel and filters disappear. Already-detected objects are kept and reappear if you re-enable.

Caveats

  • GitHub is the only built-in resolver at this release, and only github.com URLs in the exact PR/issue path shape — GitHub Enterprise hosts and other trackers need a plugin that provides object detection.
  • Resolved statuses have a short TTL (about five minutes) and there's no background poller yet at this release — statuses refresh lazily, and agents can force a refresh through the API. Expect pills to read stale or "Not yet refreshed" between resolutions.
