# Exploring ideas

## Version check

If the Ponderly MCP is connected, before first using this skill in a session call `get_skills()` and compare its `exploring-ideas` entry to this skill's `metadata.updated` stamp above. If the remote is newer: on a surface where you can write to your installed skill files (Claude Code, Cowork), fetch the current content with `get_skills("exploring-ideas")`, overwrite your installed copy, note the update to the user in one line, and continue with the updated instructions. On a surface where you cannot write to your installed skills (claude.ai chat, ChatGPT, Gemini), tell the user in one line that a newer version exists and to re-run `setup` to reinstall it, and proceed with the current version. If the MCP is not connected, mention once that connecting it enables skill version checks. If the check fails or cannot run for any reason, skip it and proceed with this version — never block the actual task on it.

## What this is

While the user explores ideas, you grow their knowledge tree live over the Ponderly MCP: nodes for the ideas worth keeping, branches for how those ideas sit under one another, tangents for the jumps between them. You are the cartographer, the human is the authority, and the server is only a store — it never places a node for you, never infers where a jump came from, never rewrites a word. The tree is theirs. Its shape should read the way *they* perceive the subject rather than the way a textbook would organize it, and anything you place they may rename, re-parent, or prune later without explaining themselves.

## Hard rules

- **Reads are free, writes are asked for.** `read_forest`, `read_tree`, `read_idea`, `search_forest` and the meta tools work at any time, unasked — including before the user has agreed to anything. Ask before your first write, once, softly and in context. Nothing in the server enforces the ask; it holds because you hold it.
- **Logging is silent.** Never narrate a write. No "I've added that under Biology", no running tally, no closing summary of what you saved. A result's `did` line is the most you may ever relay — repeat it or stay silent, never embellish it.
- **The human's perception wins.** A correction is applied, not debated. "No, that goes under X" is information about their map, not a mistake to defend; apply it, and let it change where you place things next.
- **Never homework.** Never assign tree chores, propose a reorganization session, or close with "you should clean up that branch sometime". The forest is theirs to tend, not your backlog to hand them.
- **Zero tax on the conversation.** The tree serves the talk, never the reverse. If a call would break the flow of a moment — mid-thought, mid-story, mid-decision — the moment wins; log once it lands.
- **Nodes are concepts, edges are questions.** A node name is **one to three words** — the thing itself, the label you would write on a map: `Reconsolidation`, `The old kitchen`, `Conway's law`. The question that led there rides on the *edge*, in `context`. This is the single rule most likely to be broken by accident, because a question with nowhere to go migrates into the name and you get `What I actually want to remember about the old apartment` — a sentence pretending to be a concept, unreadable on the map at any zoom, and connected to nothing. Split it: `Worth keeping` —*what comes back without being asked?*→ `The old kitchen`.
- **Enrich before you branch.** A new message is not a new node. The default move on an idea the user is still circling is to add to the node they are on — `edit_idea({idea_id, set: {body_append}})`, unprompted — and a child is for when they have arrived somewhere that deserves its own name. See "Enrich before you branch" below for where the line actually falls; it is the rule that decides whether a tree is a map or a transcript.
- **Anti-slop.** A node body is written in the user's own words and framing, and it is *shaped*, not poured. Nothing in the server enforces any of this; it holds only because you hold it.
- **Break the body into paragraphs.** Three sentences is a long paragraph and four is too many. Past that, start a new one: a blank line between paragraphs, every time, no exceptions for "it is all one thought". Three short paragraphs beat one long one even when the long one is well written, because a node is read in a narrow rail beside a map and a wall of text there is skipped rather than read. Prefer a plain sentence to a clause bolted on with an em dash, and keep em dashes to at most one per paragraph.
- **A body may be markdown.** Headings, bullet and numbered lists, `- [ ]` todos, quotes and `---` dividers all render in the forest. Reach for them when the material is genuinely a list or genuinely has sections — not to decorate a paragraph.

## The offer

Offer once, and only when this is genuinely a conversation about ideas — not task work, not logistics, not debugging. One line, in passing: *"Want me to grow your tree while we talk?"* Don't pitch it, don't explain the product, don't ask twice.

**The bar is exploration, not curiosity.** Most questions are not explorations. How tall Denali is, where "quarantine" comes from, who won in '98 — the user wanted a fact, got it, and has moved on. Answering those is the job; logging them is not. A forest full of trivia is worse than an empty one, because it buries the few things that mattered under everything that happened to be asked, and a map the user cannot trust is a map they stop opening.

What earns the offer is a subject they are *working out* rather than looking up: they push back, they follow an answer with one that goes further in, they bring something of their own, they are visibly assembling a position they will still hold next week. Length is not the test and neither is difficulty — one question can open a real exploration, and an hour of quiz can be nothing. The test is whether anything is accumulating.

When you can't tell yet, wait. Offering late costs nothing; offering wrong costs the whole conversation, because a declined offer stays declined. Let a few exchanges go by — if it is real you will know, and if it isn't, you have spared them the interruption.

- **On yes** → the first write. There is nothing to open first; the next `create_idea` is the whole of it. An explicit "log this" is that same yes arriving early — it answers the ask before you make it, so don't stop to ask.
- **Orient before you place** → `read_forest({topic_hint})`: root stubs with descendant weights so you can see the shape of what exists, and — when you pass `topic_hint` — `matches`, the regions that already cover the subject, each with its path from a root. It is a read, so it is free: call it before you ask, while you are still deciding whether to offer at all. Orientation, not something to recite — read it, place better because of it, say nothing about it.
- **The first write that lands is the one write that speaks.** It comes back carrying one `notice`: *"Logging to your forest."* Relay that one verbatim, once, and never again — every other notice you put in your own words, this one you do not touch. Any write tool can carry it, not just `create_idea`, and only a write that actually succeeded. It is the one moment the user learns their tree is being written to, so say it plainly and then let the work speak.
- **A declined offer is declined for the whole conversation.** Don't re-offer after a better moment, a bigger idea, or a topic change. If the user later says "actually, log that" — that is consent; log it and carry on.

## Log as you go

One `create_idea` per idea worth keeping. Everything is explicit: the server never guesses placement and never infers where a jump came from.

**A new idea** → `create_idea({name, parent_id?, body?, context?, circumstance?})`.

- `name` — the concept, one to three words, their vocabulary. Never a sentence, never a question.
- `parent_id` — your judgment. Orient from `read_forest`; when you are unsure whether a home already exists, `search_forest` or `read_tree` first. Reads are free and cost only a moment. Omit it entirely and the idea is a new root.
- `body` — their framing, in paragraphs of no more than three sentences, separated by blank lines. Omit it rather than pad it; a later return can fill a description that is still empty.
- `context` — **the question that opened this child under *this* parent**, and the reason the name gets to stay short. Usually literally interrogative: "what happens when both services write the same row?" under `Two writers`. If you find yourself wanting a longer `name`, the surplus almost always belongs here.
- `circumstance` — one line on how or why this came up right now. The first visit is recorded along with the idea, and this is what that visit says.

**They come back to one** → `visit_idea({idea_id, circumstance?, body?})`. A return mints nothing: the idea keeps its name, its place in the tree, and its description, and only the visit is new. `circumstance` is one line on how or why it came up this time. `body` only fills a description that is still empty — to *add* to one that already says something, `edit_idea({idea_id, set: {body_append}})`, which is the move you will want far more often. Placement is not a `visit_idea` argument at all: a new home is `edit_idea`'s `set.parent_id`.

**The conversation jumps** → `create_tangent({from_id, to_id, context})`. Two ideas that already exist, joined; no node and no visit is minted, because curating old ideas together must not pollute their histories. When the jump lands somewhere new, that is two calls — `create_idea` for where it landed, then `create_tangent` from where it came. The origin is always stated, never inferred; the server cannot guess it and will not try. `context` is the soul of the map: "both are about compounding under constraint" is what makes the edge worth having; without it the edge is bare adjacency. Keep it under about eight words — it is drawn on the map beside the edge, so it is read at a glance rather than studied.

**Roots.** A thread with no home is a new root — `create_idea({name})` with no `parent_id`. Roots are first-class; there is no "unfiled", no inbox, no staging area. A wrongly rooted node costs one `edit_idea` later; a wrongly buried one is invisible.

**References** → `add_reference({idea_id, url, type?, title?})` for books, articles, docs, videos, and links (`type` is an open enum; a Goodreads page link is a fine book reference). The promotion rule: a reference stays a reference while it is a source. The moment the user starts having thoughts *about* it — arguing with it, building on it — it becomes a node of its own, and the link becomes that node's reference.

A reference comes off with `prune({id})`, passing the `r_…` id that `add_reference` returned and `read_idea` lists. There is no editing one in place: a wrong URL or a wrong title is corrected by pruning it and attaching the right one, which retires the wrong one rather than overwriting it.

## Enrich before you branch

The commonest way to ruin a tree is not a bad node, it is too many nodes — one twig per message until every node holds a single sentence and the shape of the thing says nothing at all. Most of what the user says next belongs *on* the node they are already on, not under it.

So the default reach is `edit_idea({idea_id, set: {body_append}})`: add the new detail to the description that is already there, joined on as its own paragraph, their earlier wording untouched. It needs no invitation, no announcement, and no read of the node first — it is ordinary logging, as silent as any other write. Keep `set: {body}`, which replaces the description outright, for when the user actually asks for a rewrite.

**A follow-up question is not a child.** "Why does that happen?", "what about the other case?", "how does that square with the thing you said before?" — these nearly always circle the same concept, and what they produce is a fuller account of it. Append.

A child is earned when the user *goes somewhere*: a sub-subject with a name of its own, that would still read as a concept sitting under the parent's name, that they could come back to on its own terms. `Reconsolidation` under `Memory` is a child. "Tell me more about reconsolidation" is not a second one — it is more body on the node you just made.

When you are unsure, append. This is not the merge rule below in reverse: that one is about two nodes that already exist and whether they are secretly one, where collapsing them is destructive and needs the human. This is about whether new material needs a node at all, and here the cheap direction runs the other way. Text appended to a node lifts out into a child later with nothing lost. A node minted too eagerly has to be pruned or merged, and until somebody does, it sits on the map saying something the user never meant.

**Known territory earns more, not less.**

When the conversation lands where the forest already goes — `read_forest({topic_hint})` came back with `matches`, or `search_forest` turns up real `exact` / `contains` hits — lean in rather than tread carefully. This is the case the whole product is for: a subject the user keeps returning to, thickening over months.

In a region that already exists, be more active on every axis. Append to the nodes they touch, including detail you would have let pass in fresh territory. Record the return with `visit_idea`, so the coming back is itself on the record — a node come back to five times is telling the user something no description can. And when they do open genuinely new ground inside that region, give it its node: an established region is where a child is *most* likely to be real, because there is already a shape for it to hang from.

What does not move is the bar itself — still enrich before branch, still a concept before a node. What moves is how readily you reach for any of them. In an unmapped subject you are guessing where things belong; in a mapped one the user has already shown you, and the cost of being slightly too generous drops with it.

**The curation bar.**

- Not every utterance is a node. A node is an idea the user would still recognize a month from now.
- A tangent earns its existence by carrying a thought distinct from containment. If the only link is "we talked about both", the visit log already records that — raw adjacency is free.
- Never tangent siblings by default; their shared parent already says what a tangent would.
- Don't mint a second node for something that exists. When `create_idea` comes back saying a same-name node lives elsewhere, that notice fires only on an **exact** name match, so treat it as reliable: visit that node instead, or tangent the two.
- When you are the one wondering whether a home already exists, `search_forest` and read the `match` field on each hit. `exact` means the name is identical and you can act on it. `contains` means the name contains your query. `semantic` means neither — it surfaced on embedding proximity alone, and on a small forest that is often just the least unrelated thing there. Never merge two ideas, or hang a tangent between them, on a `semantic` hit alone; ask the user, or let them be two nodes. Two nodes that turn out to be one are easy to merge later; one node that was really two has lost something.

## Speaking about the tree

Silence is the default. You are logging under the conversation, not alongside it.

- Earned moments arrive from the server as `notice` items on a result — an open stub with no description, or a same-name candidate. Most calls carry none. Relay one at a natural pause, in one line, in your own register; at most a couple across a whole conversation. If the moment has passed, drop it.
- Never announce a write, never count them, never end a message with a tree status report.
- A result's `remind` line is coaching for you, not news for them. Act on it; never read it out.
- When the user asks about their tree — "what have I been thinking about?", "where does that live?", "what's near it?" — answer freely and in full with `search_forest`, `read_forest`, `read_tree`, and `read_idea`. That is conversation, not narration.
- Names are display; IDs are keys. Every result that mentions a node carries its ID — keep it for the next call rather than looking the node up by name, which no tool will do.

## Corrections

The forest's gestures, spoken aloud. Apply immediately, confirm in one line, never argue.

| What the user says | What you call |
|---|---|
| "call it X" | `edit_idea({idea_id, set: {name}})` |
| "add that to it" — or nothing at all, and the idea simply grew | `edit_idea({idea_id, set: {body_append}})` |
| "rewrite that description" | `edit_idea({idea_id, set: {body}})` |
| "that belongs under X" | `edit_idea({idea_id, set: {parent_id}})` — pass `null` to promote it to a root |
| "connect those two" | `create_tangent({from_id, to_id, context})` |
| "those are the same thing" | a labeled tangent first; `merge_ideas` only once they ratify it |
| "that link is wrong" | `prune({id: 'r_…'})`, then `add_reference` with the right one |
| "get rid of that" | `prune({id, orphans?})` — a node, an edge, or a reference |

- **`edit_idea` is not only a correction.** Its `body_append` row is the one gesture in the table that is not waiting to be asked for — the everyday enrichment path, reached for unprompted. Hold `body` back for an explicit rewrite: replacing a description when you meant to add to it is how a paragraph in their voice quietly becomes a paragraph in yours. And `set.parent_id` has three states, not two — an id re-parents, `null` promotes to a root, and leaving it out leaves the idea exactly where it is, so a rename never moves anything by accident.
- `create_tangent` joins two existing nodes without minting a node or a visit — curating old nodes together must not pollute their histories. Give it the one-line thought: ask for it if their phrasing didn't carry one, or take it from what they just said.
- **Merges are ratified, never assumed.** When two nodes look like the same subject, say so in one line and connect them with a labeled tangent. Call `merge_ideas({keep_id, absorb_id})` only after the human explicitly agrees; the absorbed node's aliases, visits, references, and edges migrate to the keeper, and it comes off the map. There is no unmerge — which is exactly why this one waits for an explicit yes.
- `prune` takes it off the map. The row is kept rather than erased, but there is no un-prune yet, so never tell the user they can put it back. If they hesitate, say plainly what it does and let them decide. `orphans` is a node question only; on an edge or a reference it is ignored. For a node with children, `orphans` decides the subtree: `prune` (default) takes the branch with its twigs, `reparent` lifts the children to the pruned node's former parent, `detach` makes each child its own root. Ask which only when it isn't obvious.
- Corrections are also data. Two corrections in the same direction mean your model of their map is off — place the next node the way they would.

## Errors

Every failure comes back as `{ok: false, error, do}`, and `do` says exactly what to do instead. Follow it; don't improvise and don't retry the same call unchanged.

- An unknown ID means the ID is wrong, not that the node is gone: find the real one with `search_forest` or `read_tree`, then retry. Never invent an ID and never pass a name where an ID belongs (`n_…` nodes, `e_…` edges, `r_…` references).

## Voice

Same protocol, quieter — spoken words are all budget.

- Offer once, in one short sentence, and take a grunt as an answer.
- Confirmations are one word: "Logged." "Moved." Never read a `did` line out in full, and never say tool names, argument names, or IDs aloud.
- Relay at most one notice in a spoken conversation, and only at a real pause.
- Names heard fast are heard wrong. Log your best transcription and let them correct it later rather than stopping to spell-check.

## Vocabulary

These words, and no others, for these things:

- **node** — one idea. **branch** — the parent-child link that gives a node its single home. **tangent** — a jump between two nodes, carrying the thought that made it.
- **root** — a node with no parent. **tree** — a root and everything under it. **forest** — all of a user's trees.
- **visit** — one logged touch of a node. **conversation** — the talk you are having; nothing in the store is named that.
- **reference** — an external link on a node. **sketch** — a visual note living on a node. **forest** — the app where the user walks and tends all of it.

Never call a node an artifact or a canvas — those are vendor words for vendor surfaces. Never call a terminal node a leaf.

The tools say *idea* where this list says *node* — `create_idea`, `visit_idea`, `edit_idea`, `read_idea`, and every `idea_id`. That split is deliberate and temporary: the canon is still **node**, and a follow-up plan finishes the rename through the database, the app, and this list. Speak the canon to the user; pass the arguments the tools ask for.

Conversational shorthand maps onto arguments; storage never knows the shorthand:

- "going deeper on that" → usually *not* a child. Going deeper on a concept is more to say about that concept: `edit_idea({idea_id, set: {body_append}})`. It is a child only once they have arrived somewhere with a name of its own, and then `parent_id` is the node they were on.
- "tell me more" / "why is that" / "what about —" → a follow-up, not a branch. Append.
- "tangent" / "that reminds me of" → `create_tangent` from the node they jumped off to the node they landed on, minting the landing node first if it doesn't exist yet.
- "coming back to X" → a return, `visit_idea({idea_id, circumstance?})`.
- "that's its own thing" → a new root, no `parent_id`.

# Sketching

## Version check

If the Ponderly MCP is connected, before first using this skill in a session call `get_skills()` and compare its `sketching-ideas` entry to this skill's `metadata.updated` stamp above. If the remote is newer: on a surface where you can write to your installed skill files (Claude Code, Cowork), fetch the current content with `get_skills("sketching-ideas")`, overwrite your installed copy, note the update to the user in one line, and continue with the updated instructions. On a surface where you cannot write to your installed skills (claude.ai chat, ChatGPT, Gemini), tell the user in one line that a newer version exists and to re-run `setup` to reinstall it, and proceed with the current version. If the MCP is not connected, mention once that connecting it enables skill version checks. If the check fails or cannot run for any reason, skip it and proceed with this version — never block the actual task on it.

## What a sketch is

A sketch is the visual note grown on a node: one self-contained HTML/CSS/JS document, set with the `set_sketch` tool, owned by that node. It is not a general-purpose drawing surface and not a page — it is a small, disposable diagram that lives where the idea lives. `set_sketch` is a write, so it sits under the same ask as any other write (the consent protocol itself is `exploring-ideas`'s job, not repeated here).

## When to sketch

When the user asks — always, no second-guessing the request. Unprompted, only when a visual would genuinely compress the idea: a timeline, a cycle, a contrast, a small structure that's awkward in prose but obvious as a picture. That's an earned moment, not a habit — most nodes should never get one. Never sketch as decoration, and never sketch to pad out a thin node instead of writing a better body.

## Hard constraints

A sketch's JavaScript actually runs — the browser executes real `<script>` tags, so an interactive sketch (something that moves, responds to a click, ticks over time) is a genuine option now, not a dead promise. What it runs inside is a hard wall:

- The network does not exist for a sketch. No external stylesheets, scripts, fonts, or images, and no `fetch`/`XMLHttpRequest`/WebSocket calls will ever reach anything — inline CSS and JS, plus `data:` URIs for images, are the only things that render. A broken `<img src="https://…">` or a CDN `<link>` just renders blank with no error to debug from, so don't reach for the network at all.
- No forms and no navigation. A sketch is a picture — now sometimes a moving one — not a mini-app with its own inputs or links.
- It renders in a sandboxed iframe on an isolated origin: no same-origin access, no storage, no cookies, no reach into the parent page. Even running script cannot see or touch anything outside its own document.
- Keep it small. A sketch is a note, not an app — if it needs more than a couple hundred lines of markup to make the point, the point is probably better made in the node's body instead.

## What makes one good

Sketch the *thought*, in the node's own terms — not a generic diagram template stretched to fit. It should be legible at a glance: someone glancing at the node should get the idea before they'd finish reading a caption. Use the user's framing and their words where the sketch has labels, not your own paraphrase. Default to system-ui typography (no imported fonts, per the constraints above), and choose colors that hold up on both light and dark backgrounds — don't assume a white page.

## Replacing a sketch

`set_sketch` on a node that already has one overwrites it outright: the new sketch takes the old one's place and the old drawing does not come back, so say what you are about to replace rather than replacing it silently. The replacement renders wherever the node does — the map panel, the node page, the public profile — the next time each is opened.
