Matt Pocock 77cc47773c docs: rework the skill docs-page template
Reframe docs pages around cognitive-load relief: most skills are
user-invoked, so the human is the index that must remember when to
reach for each one. Each page's job is to make one skill memorable
and situate it in the system.

Template changes (.agents/writing-docs.md):
- Quickstart block: install + `npx skills update`, install-first
- New `## When to reach for it` (invocation mode + trigger boundary)
- New optional `## Prerequisites` (workspace/state, prior setup, tooling)
- Free-form middle with one firm rule: surface the leading word
  (also an observability signal in the agent's output)
- `## Where it fits`: role-based, absorbs "Pairs well with", links ask-matt
- No H1; every cross-link absolute

Nest docs under bucket folders (docs/<bucket>/<name>.md); the
published URL stays skills-<name> regardless. Re-sync to-prd as the
worked exemplar.

## What it does
`to-prd` turns the current conversation and your codebase understanding into a product requirements document, then publishes it to your issue tracker.
The load-bearing constraint: it does **not** interview you again. By the time you reach for it, the alignment work is done — `to-prd` synthesises what is already known rather than asking a fresh round of questions.
## When to reach for it
You invoke this by typing `/to-prd` — the agent won't reach for it on its own.
Reach for it once a change has been talked through and the domain language is settled, and you want that shared understanding written down as a spec before any code is written. If you *haven't* aligned yet, grill first — for that, use [grill-with-docs](https://aihero.dev/skills-grill-with-docs). To split the finished PRD into tickets, use [to-issues](https://aihero.dev/skills-to-issues).
## Prerequisites
`to-prd` publishes into your issue tracker, so [setup-matt-pocock-skills](https://aihero.dev/skills-setup-matt-pocock-skills) must have configured the tracker and triage labels for this repo first. It applies the `ready-for-agent` label itself — no separate triage pass needed.
## What the PRD includes
- problem statement
- solution
- extensive numbered user stories
- implementation decisions
- testing decisions
- out-of-scope items
- further notes
## Deep modules
Before writing the PRD, `to-prd` sketches the **seams** at which the feature will be tested and looks for **deep module** opportunities — a lot of functionality hidden behind a small, stable interface. It prefers existing seams to new ones and the highest seam possible, ideally just one across the whole change.
That matters for agentic development: a good interface gives tests something durable to target, so the code underneath can change without the tests moving. If you see the words _seam_ and _deep module_ coming back at you as it works, the skill is doing its job.
## Where it fits
`to-prd` is a step in the main build chain:
```txt
grill-with-docs → to-prd → to-issues → tdd
```
Reach for it after the plan and domain language are resolved, and before you break the work into implementation tickets. Its key neighbours are [grill-with-docs](https://aihero.dev/skills-grill-with-docs), which sharpens the context so the PRD is precise, and [to-issues](https://aihero.dev/skills-to-issues), which turns the PRD into independently-grabbable issues for [tdd](https://aihero.dev/skills-tdd) to implement. When you're unsure which skill or flow fits, [ask-matt](https://aihero.dev/skills-ask-matt) routes you.
