Add Task ticket type to decision-mapping skill

Some blockers are neither a decision, a prototype, nor research — just
literal manual work (moving data, signing up for a service, provisioning
access) that must happen before discussion can move forward.

+# Writing docs pages
+
+Every promoted skill (`engineering/`, `productivity/`, `misc/`) has a human-facing **docs page** at `docs/<skill-name>.md`, published at `https://aihero.dev/skills-<skill-name>`. The page is not the skill and not a copy of `SKILL.md` — it is the explainer a human reads to decide whether to reach for the skill. Skills in `personal/`, `in-progress/`, and `deprecated/` get no page, mirroring the README rule.
+
+Act whenever a promoted skill is added, renamed, or has its behaviour changed: create or re-sync its docs page. A rename moves the file too (`docs/<old>.md` → `docs/<new>.md`), because the published URL tracks the name.
+
+Because these pages are published on `aihero.dev`, **every link is absolute** — never a repo-relative path. A link to another skill points at `https://aihero.dev/skills-<name>`; a link into the repo points at its full `https://github.com/mattpocock/skills/...` URL. A relative link that works in the repo breaks once published.
+
+## Page structure
+
+Fill the template below. The **fixed frame** (install block, source link, `## What it does`) appears on every page. The **adaptable middle** carries only the sections this particular skill earns — delete the ones it doesn't.
+
+<page-template>
+
+```bash
+npx skills add mattpocock/skills --skill=<name>
+```
+
+[Source](https://github.com/mattpocock/skills/tree/main/skills/<bucket>/<name>)
+
+## What it does
+
+One or two plain-language paragraphs. Lead with the skill's one-sentence job, then state the **load-bearing constraint** — the single fact that makes this skill behave differently from the obvious default (for `to-prd`: it does not interview the user again, it synthesises what is already known). This line is the most valuable on the page; never omit it.
+
+## <Substance heading>
+
+Unpack what the skill produces or how it moves — e.g. a list of the artifact's parts, or a description of the loop it runs. Use as many of these sections as the skill needs; omit if it needs none.
+
+## <Concept highlight>
+
+Name the one idea worth calling out, in the skill's own vocabulary, and say why it matters (`to-prd`'s `## Deep modules` explains what a deep module is and why it helps agentic testing). Omit if there is none.
+
+## How it fits the workflow
+
+```txt
+grill-with-docs → to-prd → to-issues → tdd
+```
+
+A sentence on where in that chain to reach for the skill. Include only when the skill belongs to a chain.
+
+## Pairs well with
+
+- [<sibling>](https://aihero.dev/skills-<sibling>), because-clause saying what the pairing buys
+
+</page-template>
+
+## Conventions
+
+- Explain the **why**, not the process. The page sells and situates the skill; it never reproduces the `SKILL.md` steps or template dumps — a human choosing a tool does not need the runbook.
+- Use the skill's **leading words** (_seam_, _deep module_, _tracer bullet_) so the page and the skill speak one language.
+
+## Done when
+
+- The page exists at `docs/<name>.md`, and no stale page survives a rename.
+- The install command and source link name the correct bucket and skill.
+- The load-bearing constraint is stated in `## What it does`.
+- Every link is absolute, and every one resolves.

+Add a fourth **Task** ticket type to the **`decision-mapping`** skill. Some blockers are neither a decision, a prototype, nor research — just literal manual work that has to happen before the discussion can move forward (moving data, signing up for a third-party service, provisioning access). The agent automates it where it can, otherwise hands the human a precise checklist, and records any resulting facts later tickets depend on.

+
+[Source](https://github.com/mattpocock/skills/tree/main/skills/engineering/to-prd)
+
+## What it does
+
+`to-prd` turns the current conversation context and codebase understanding into a product requirements document.
+
+The important constraint is that it does not interview the user again. It synthesizes what is already known.
+
+## What the PRD includes
+
+The generated PRD includes:
+
+- problem statement
+- solution
+- extensive numbered user stories
+- implementation decisions
+- testing decisions
+- out-of-scope items
+- further notes
+
+The skill also asks the agent to sketch the major modules that need to be built or modified.
+
+## Deep modules
+
+`to-prd` actively looks for deep module opportunities.
+
+A deep module hides meaningful complexity behind a small, stable, testable interface. That matters for agentic development because a good interface gives tests something durable to target.
+
+## How it fits the workflow
+
+```txt
+grill-with-docs → to-prd → to-issues → tdd
+```
+
+Use `to-prd` after the plan and domain language have been resolved. Then use `to-issues` to break the PRD into tracer-bullet implementation issues.
+
+## Pairs well with
+
+- [grill-with-docs](https://aihero.dev/skills-grill-with-docs), to make sure the context is precise before the PRD is written
+- [to-issues](https://aihero.dev/skills-to-issues), to turn the PRD into implementation tickets
+- [tdd](https://aihero.dev/skills-tdd), to implement the resulting issues one behavior at a time

 - **Research**: Reading documentation, third-party API's, or local resources like knowledge bases. Creates a markdown summary as an asset. Use this when knowledge outside the current working directory is required.
-- **Prototype**: Writing UI or logic code to test a hypothesis, or to explore a design space. Uses the /prototype skill. Creates a prototype as an asset. Use this when "how should it look" or "how should it behave" is the key question.
+- **Prototype**: Raise the fidelity of the discussion by making a cheap, rough, concrete artifact to react to — an outline, a rough take, a stub, or UI/logic code via the /prototype skill. Creates the prototype as an asset. Use this when "how should it look" or "how should it behave" is the key question.
 - **Grilling**: Conversation with the agent. Uses the /grilling and /domain-modeling skills. Asks one question at a time. The default case.
+- **Task**: Literal manual work that must be done before the discussion can move forward — nothing to decide, prototype, or research.
