This skill is invoked when a loose idea requires more than one agent session to turn into a plan. It creates a stateful decision map in a markdown file, and drives the user through a sequence of tickets to resolve the open questions - which may require either prototyping, research or grilling. The map is domain-agnostic: it plans engineering work, course content, or anything else that fits the same shape.

The Decision Map

The decision map is a single compact Markdown file, one per planning effort, git-tracked alongside the project. It is the canonical artifact — the whole map is loaded as context into every session, so it must stay compact.

Assets created during tickets should be linked to from the map, not duplicated within it.

Structure

Entries ("tickets"), each its own section keyed by a short dash-case slug that reads as a mini-title (e.g. relational-db, auth-strategy, cache-layer) — terse enough to stay token-efficient, and unique within the map.

## relational-db: Relational Or Non-Relational Database?
 
Blocked by: <slug>, <slug>
Status: open | in-progress | resolved
Type: Research | Prototype | Grilling
 
### Question
 
<question-here>
 
### Answer
 
<answer-here>

The slug is the canonical id, used in every Blocked by edge and prose reference; the title after the colon is optional. A ticket is unblocked when every ticket in its Blocked by list is resolved. A session claims its ticket by setting Status: in-progress and saving the map before any work, so concurrent sessions skip it.

Each ticket must be sized to one 100K token agent session.

Ticket Types

There are three types of tickets:

• 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: 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.

Validation isn't a fourth type — it's the thread running through all three.

Fog of war

The map is _deliberately_ incomplete beyond the frontier. Your job is to investigate the frontier, and to resolve tickets in order to push the frontier forward. Push back the fog of war, one node at a time — until the path to the finish line is clear and no tickets remain.

Invocation

Two branches. Either way, every session ends with a [Handoff](#handoff) — never resolve more than one ticket per session.

Create the map

User invokes with a loose idea.

1. Run a /grilling and /domain-modeling session to surface the open decisions. Ask one question at a time.
2. Write a new decision map — mostly fog, frontier identified, trivially-decidable entries resolved inline.
3. Handoff. Map-building is one session's work; do not also resolve tickets.

Work through the map

User invokes with a path to an existing map. A ticket slug is optional — without one, you pick the next decision, not the user.

1. Load the whole map as context.
2. Choose the ticket. If the user named one, use it. Otherwise pick the first open ticket in document order that is unblocked. Claim it: set Status: in-progress and save before any work.
3. Resolve it, invoking skills as needed — including any the ## Notes block names. If in doubt, use /grilling and /domain-modeling.
4. Record the answer in the ticket's body and set Status: resolved.
5. Add newly-discovered tickets with correct Blocked by edges. If the decisions made invalidate other parts of the map, update or delete those nodes.
6. Handoff.

The user may run unblocked tickets in parallel, so expect other agents to be editing the map in their own sessions.

Handoff

End every session by clearing the context and opening one or more fresh sessions. Close with a Next steps block the user can copy-paste. Two cases:

Open tickets remain. List the currently-unblocked tickets, then give two copy-paste options: a bare command for one session (you pick the next ticket), and one pinned command per unblocked ticket for running them in parallel. Paste one line per fresh window — opening one, some, or all of them.

Next steps — 3 tickets unblocked: auth-strategy, cache-layer, rate-limits.

Clear the context, then open fresh sessions.

One session — resolves the next unblocked ticket:

```

Invoke /decision-mapping with the map at <path>.

```

Parallel — paste one line per window, up to all 3:

```

Invoke /decision-mapping with the map at <path>, ticket auth-strategy.

Invoke /decision-mapping with the map at <path>, ticket cache-layer.

Invoke /decision-mapping with the map at <path>, ticket rate-limits.

```

No open tickets remain. The fog is pushed back far enough that the path to the finish line 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 build.) Recommend implementing directly, or using /to-prd to schedule a multi-session implementation.

Notes

An optional block declaring the domain, any skills every session should consult, and freeform standing preferences the planning surfaces.
