Drop Negative Space; keep Negation only

Negative Space read as clever but not actionable — "notice your
silences" is fuzzy legwork the agent can't reliably act on. Negation
stays: a checkable authoring failure with a positive-instruction cure.

 The split keeps soft-dependency skills token-light and avoids cargo-culting the setup pointer into places where it isn't load-bearing.

+Give **`wayfinder`** a first-class notion of **out of scope**, separate from fog.
+
+Fog and out-of-scope were conflated under one `## Fog` map section, gated by different things: fog by *knowledge* (can't specify it yet — in scope, unripe, graduates as the frontier advances), out-of-scope by *scope* (beyond the destination — never graduates). Cramming both under "Fog" made out-of-scope work read as takeable frontier (an unblocked, unclaimed item is indistinguishable from a live ticket).
+
+Now the map body has two plainly-named sections — **`## Not yet specified`** and **`## Out of scope`** — and the skill's prose splits to match: the **Fog of war** section teaches only the not-yet-specified bucket and keeps the two-way *fog-or-ticket* sharpness test, while a new **Out of scope** section owns the scope axis (beyond the destination, closed not graduating, returns only as a fresh effort if the destination is redrawn). Charting and working-the-map now rule a beyond-destination ticket out of scope — close it, one line in *Out of scope* — rather than leaving it on the frontier or logging it in *Decisions so far*.

+## What it does
+
+`research` answers a question by reading the sources that own the answer and leaving a cited Markdown file behind. It works only from **primary sources** — official docs, source code, specs, first-party APIs — never a secondary write-up of them, so what it saves is traceable back to something authoritative rather than a summary of a summary.
+
+## When to reach for it
+
+Type `/research`, or the agent reaches for it automatically when a task turns into reading legwork.
+
+Reach for it when the next step is *finding something out* — how an API behaves, what a spec actually says, whether a claim holds — and you'd rather not stall your own thread doing the reading.

+
+## Delegated legwork
+
+The defining move is that the reading runs as a **background agent**. You keep working; it goes off, follows each claim back to its primary source, and drops a single cited Markdown file into wherever the repo keeps such notes. Research is legwork you delegate, not thinking you outsource — you get back a document to react to, with its sources attached.

+## What it does
+
+`to-issues` breaks a plan, spec, or PRD into a set of independently-grabbable issues and publishes them to your project's issue tracker, in dependency order.
+
+Every issue is a **tracer bullet** — a thin *vertical* slice that cuts through all integration layers end-to-end (schema, API, UI, tests), never a horizontal slice of one layer. A completed slice is demoable or verifiable on its own, which is what makes the resulting tickets safe to hand to independent agents.
+
+## When to reach for it
+
+You invoke this by typing `/to-issues` — the agent won't reach for it on its own.
+
+Reach for it once you have an agreed plan or a written spec and you want it split into tickets an agent can pick up. Point it at the conversation, or pass an existing issue reference and it fetches the body and comments first. If the change hasn't been written up as a spec yet, produce one first — for that, use [to-prd](https://aihero.dev/skills-to-prd).
+
+## Prerequisites
+
+`to-issues` publishes into your issue tracker, so [setup-matt-pocock-skills](https://aihero.dev/skills-setup-matt-pocock-skills) must have configured the tracker and its triage label vocabulary for this repo first. It applies the ready-for-agent triage label itself as it publishes.
+
+## Vertical slices, not horizontal ones
+
+The whole skill turns on one distinction. A **horizontal** slice ships one layer of the change — all the schema, or all the API — and nothing works until every layer lands. A **vertical** slice, the tracer bullet, ships one narrow path through *every* layer at once, so it can be demoed the moment it's done.
+
+Before slicing, `to-issues` looks for prefactoring — "make the change easy, then make the easy change" — and orders that work first. It then quizzes you on the breakdown (granularity, dependencies, what to merge or split) before writing anything, and publishes blockers first so each issue's "Blocked by" field can reference a real ticket.

-
-## One artifact, two readings
-
-The blocking edges are the whole point. They make one set of tickets read two ways, depending on the tracker:
-
-- **Local files** → a single `tickets.md` in the repo root, the edges written as text. You work it top-to-bottom, by hand, staying in the loop.
-- **A real tracker (GitHub, Linear)** → one issue per ticket, the edges as native blocking links (or sub-issues). Any ticket whose blockers are all done is on the **frontier** and can be grabbed — so several agents can run at once.
-
-The edges live in the ticket regardless of medium; the medium only decides whether anything acts on them in parallel. `to-tickets` produces the artifact — how you run it (sequential by hand, or a parallel fleet) is up to you.
-
-## Vertical slices, not horizontal ones

+# To Issues
+
+Break a plan into independently-grabbable issues using vertical slices (tracer bullets).
+
+The issue tracker and triage label vocabulary should have been provided to you — run `/setup-matt-pocock-skills` if not.
+
+## Process
+
+### 1. Gather context
+
+Work from whatever is already in the conversation context. If the user passes an issue reference (issue number, URL, or path) as an argument, fetch it from the issue tracker and read its full body and comments.
+
+### 2. Explore the codebase (optional)
+
+If you have not already explored the codebase, do so to understand the current state of the code. Issue titles and descriptions should use the project's domain glossary vocabulary, and respect ADRs in the area you're touching.
+
+Look for opportunities to prefactor the code to make the implementation easier. "Make the change easy, then make the easy change."
+
+### 3. Draft vertical slices
+
+Break the plan into **tracer bullet** issues. Each issue is a thin vertical slice that cuts through ALL integration layers end-to-end, NOT a horizontal slice of one layer.
+
+<vertical-slice-rules>
+
+- Each slice delivers a narrow but COMPLETE path through every layer (schema, API, UI, tests)
+- A completed slice is demoable or verifiable on its own
+- Any prefactoring should be done first
+
+</vertical-slice-rules>
+
+### 4. Quiz the user
+
+Present the proposed breakdown as a numbered list. For each slice, show:
+
+- **Title**: short descriptive name
+- **Blocked by**: which other slices (if any) must complete first
+- **User stories covered**: which user stories this addresses (if the source material has them)
+
+Ask the user:
+
+- Does the granularity feel right? (too coarse / too fine)
+- Are the dependency relationships correct?
+- Should any slices be merged or split further?
+
+Iterate until the user approves the breakdown.
+
+### 5. Publish the issues to the issue tracker
+
+For each approved slice, publish a new issue to the issue tracker. Use the issue body template below. These issues are considered ready for AFK agents, so publish them with the correct triage label unless instructed otherwise.
+
+Publish issues in dependency order (blockers first) so you can reference real issue identifiers in the "Blocked by" field.
+
+<issue-template>
+## Parent
+
+A reference to the parent issue on the issue tracker (if the source was an existing issue, otherwise omit this section).
+
+## What to build
+
+A concise description of this vertical slice. Describe the end-to-end behavior, not layer-by-layer implementation.
+
+Avoid specific file paths or code snippets — they go stale fast. Exception: if a prototype produced a snippet that encodes a decision more precisely than prose can (state machine, reducer, schema, type shape), inline it here and note briefly that it came from a prototype. Trim to the decision-rich parts — not a working demo, just the important bits.
+
+## Acceptance criteria
+
+- [ ] Criterion 1
+- [ ] Criterion 2
+- [ ] Criterion 3
+
+## Blocked by
+
+- A reference to the blocking ticket (if any)
+
+Or "None - can start immediately" if no blockers.

-# To Tickets
-
-Break a plan, spec, or conversation into a set of **tickets** — tracer-bullet vertical slices, each declaring the tickets that **block** it.
-
-The issue tracker and triage label vocabulary should have been provided to you — run `/setup-matt-pocock-skills` if not.
-
-## Process
-
-### 1. Gather context
-
-Work from whatever is already in the conversation context. If the user passes a reference (a spec path, an issue number or URL) as an argument, fetch it and read its full body and comments.
-
-### 2. Explore the codebase (optional)
-
-If you have not already explored the codebase, do so to understand the current state of the code. Ticket titles and descriptions should use the project's domain glossary vocabulary, and respect ADRs in the area you're touching.
-
-Look for opportunities to prefactor the code to make the implementation easier. "Make the change easy, then make the easy change."
-
-### 3. Draft vertical slices
-
-Break the work into **tracer bullet** tickets.
-
-<vertical-slice-rules>
-
-- Each slice cuts a narrow but COMPLETE path through every layer (schema, API, UI, tests) — vertical, NOT a horizontal slice of one layer
-- A completed slice is demoable or verifiable on its own
-- Each slice is sized to fit in a single fresh context window
-- Any prefactoring should be done first
-
-</vertical-slice-rules>
-
-Give each ticket its **blocking edges** — the other tickets that must complete before it can start. A ticket with no blockers can start immediately.
-
-### 4. Quiz the user
-
-Present the proposed breakdown as a numbered list. For each ticket, show:
-
-- **Title**: short descriptive name
-- **Blocked by**: which other tickets (if any) must complete first
-- **What it delivers**: the end-to-end behaviour this ticket makes work
-
-Ask the user:
-
-- Does the granularity feel right? (too coarse / too fine)
-- Are the blocking edges correct — does each ticket only depend on tickets that genuinely gate it?
-- Should any tickets be merged or split further?
-
-Iterate until the user approves the breakdown.
-
-### 5. Publish the tickets to the configured tracker
-
-Publish the approved tickets. **How** depends on the tracker `/setup-matt-pocock-skills` configured — the tickets are the same either way, only the shape of the blocking edges changes:
-
-- **Local files** → write one `tickets.md` in the repo root, all tickets in dependency order (blockers first), each with its "Blocked by" listing the titles it depends on. Use the file template below.
-- **A real issue tracker (GitHub, Linear, …)** → publish one issue per ticket in dependency order (blockers first) so each ticket's blocking edges can reference real identifiers. Use the platform's native blocking / sub-issue relationship where it has one; otherwise set each ticket's "Blocked by" to the blocking issues. Apply the `ready-for-agent` triage label unless instructed otherwise — the tickets are agent-grabbable by construction.
-
-Do NOT close or modify any parent issue.
-
-<tickets-file-template>
-
-# Tickets: <short name of the work>
-
-A one-line summary of what these tickets build. Reference the source spec if there is one.

-Work the **frontier**: any ticket whose blockers are all done. For a purely linear chain that means top to bottom.
-

Exception: if a prototype produced a snippet that encodes a decision more precisely than prose can (state machine, reducer, schema, type shape), inline it and note briefly that it came from a prototype. Trim to the decision-rich parts — not a working demo, just the important bits.
-
-Work the frontier one ticket at a time with `/implement`, clearing context between tickets.

+
+## Out of scope
+
+Fog only ever gathers _toward_ the destination. The destination fixes the scope, so work beyond it is **out of scope** — it isn't fog, and it doesn't belong in **Not yet specified**. It gets its own **Out of scope** section on the map: work you've consciously ruled out of _this_ effort. Scope, not sharpness, lands it here.
+
+Out-of-scope work never graduates — the frontier stops at the destination — so it returns only if the destination is redrawn, and then as a fresh effort, not a resumption.
+
+Ruling something out of scope is a scoping act, not a step on the route. When a ticket that already exists turns out to sit past the destination — mis-scoped in while charting, or exposed by a resolution — **close it** (a closed ticket is unambiguously off the frontier) and leave one line in the **Out of scope** section: the gist plus why it's out of scope, linking the closed ticket.

Paste one line per fresh window — opening one, some, or all of them.
-

->
-> **One session** — resolves the next unblocked ticket:
-> ```
-> Invoke /wayfinder with the map <map-url>.
-> ```
->
-> **Parallel** — paste one line per window, up to all 3:
-> ```
-> Invoke /wayfinder with the map <map-url>, ticket <issue-url>.
-> Invoke /wayfinder with the map <map-url>, ticket <issue-url>.
-> Invoke /wayfinder with the map <map-url>, ticket <issue-url>.
-> ```
-
-**No open tickets remain.** The fog is pushed back far enough that the way to the goal is clear — the map is done. (The initial grilling may also surface no fog at all, in which case there was never a map to chart.) Recommend implementing directly, or using `/to-spec` to schedule a multi-session implementation.
