Cg Config

cg-config — interpret and recommend Cartograph setup

The tools for reading and writing config are already available as MCP calls. This skill is not about how to use them. It's about how to interpret what the user has and recommend coherent setups when they ask.

The skill runs in one of two modes depending on what the user wants.

• Briefing mode — user wants to know what their current setup does. Interpret, don't editorialize. See "Briefing mode" below.
• Recommendation mode — user wants to know what their setup should be given an intent. Propose a named profile, explain the tradeoff, apply on confirm. See "Recommendation mode" below.

Don't mix the two. If the user opens with a briefing request, don't drift into recommendations. If they open with an intent, don't deliver a full briefing first — offer profiles directly.

Tool boundary

Prefer cartograph_config for reading or changing config keys exposed by the MCP surface. Use the cartograph CLI for registry management, auth state, doctor output, path diagnostics, or settings that are not currently exposed as MCP tools.

Agent setup

Config covers Cartograph's own defaults, but the agent also needs to know Cartograph exists. That lives in the agent's instructions file (e.g. CLAUDE.md, AGENTS.md) and is written by the CLI:

cartograph setup

The command auto-detects the agent, appends Cartograph instructions to the right file, and never replaces existing content. Useful flags:

• --agent <name> force a specific agent when auto-detect is wrong or the user works with multiple agents.
• --file <path> target a specific file instead of the auto-detected one.
• --print print the instructions to stdout instead of writing, useful when the user wants to review before committing.

When to surface this:

• The user asks how to connect a new agent to Cartograph.
• The user is on an agent that doesn't ship a Cartograph plugin (bare CLI, Aider, Cursor without the MCP registered, etc).
• The user reports the agent "doesn't seem to know about widgets" despite the MCP being live.

Skip it when the user is already running the Cartograph plugin for their agent — the plugin ships its own teaching layer and cartograph setup would duplicate it.

Briefing mode

Frame the briefing as three workflow questions

Not a setting-by-setting readout. Synthesize the config + registry list + doctor output into three short paragraphs, in this order:

1. "What happens when I check in a widget?"

Reads: auto-publish, publish-registry, visibility, governance.

These four combine into one sentence about the user's publishing flow. Common combinations:

• auto-publish on, registry=cg: every checkin pushes to the public cg community registry. All cg widgets are public, so visibility is inert here — don't pretend it matters. Governance governs whether the community can propose changes.
• auto-publish off, registry=cg: checkin stays local; publishing is a separate manual step. Still public-only when the user chooses to push.
• auto-publish on, registry=: every checkin pushes to that registry honoring visibility — private means invited collaborators only.
• auto-publish off, registry=: checkin stays local; publishing is a separate manual step when the user chooses to push.

If the config output flags visibility.effective=false, say that directly — the CLI already encodes the "no-op on cg" rule, trust it.

2. "What do you see when I search?"

Reads: cloud enabled state, configured registries, show-unavailable.

One sentence. Cloud enabled or not; which registry or registries the user is pulling from; whether results include widgets for languages they can't actually run.

If only the default cg registry is configured, say that directly. Don't list it as if it were a deliberate choice — it's the default.

3. "What runs locally?"

Reads: doctor output (engine availability) + any paths.* overrides.

One sentence. Which engines are available, which are missing, and whether the user has pointed Cartograph at any custom binary locations. If an engine is missing, mention that widgets in that language won't validate or install — factual consequence, not a scolding.

Recommendation mode

User's intent is the starting point, not the current config. Map the intent to one or two of the four named profiles below, surface the tradeoffs, let them pick.

The four profiles

1. Local-only. "I want Cartograph as a local widget manager. No sharing."

• cloud=false, auto-publish=false, show-unavailable=false
• Everything stays on disk. Useful for exploration, air-gapped machines, or corporate environments that can't reach external networks.

2. Community contributor. "I want to pull from the public library and push back when I've polished something."

• cloud=true, publish-registry=cg, auto-publish=false, governance=open
• visibility is moot on cg. The auto-publish=false gives the user a review window before each push.

3. Eager contributor. "Everything I check in should be public immediately."

• Same as Community contributor but auto-publish=true.
• Tradeoff to name out loud: zero friction, but also zero "wait I wasn't done yet" window — every successful checkin becomes a public release on cg.

4. Organization member. "I work at a company hosting its own registry. I want widgets to go there by default, privately."

• cloud=true, <org prefix> added via registry add, publish-registry=<org>, visibility=private, auto-publish=false
• The only profile where visibility is load-bearing. Requires the user to know (or ask) their org's registry URL.

Conversation shape

1. Narrow based on what the user said. Don't list all four. If they said "I want everything private" offer 1 and 4. If they said "I want to share publicly" offer 2 and 3. If they said "help me set up" ask a clarifying question first.
2. Describe each offered profile in three lines: name, the one intent sentence, the concrete settings.
3. Name the tradeoff for each. Don't pretend there isn't one.
4. User picks one or says none fit.
5. Show the diff between current config and the profile — only what would change. Four changed keys is more trustworthy than "apply this profile" as an opaque operation.
6. Apply on confirmation, one setting at a time (same discipline as Briefing mode's change loop).

Integration with Briefing mode

If the user finished a briefing and their current config looks incoherent (cloud off but auto-publish on, overriding paths for engines that don't exist, etc), the briefing may end with: "If you want to walk through a clean setup, I can suggest profiles." That's a hand-off into Recommendation mode, not an editorial push.

Never flip into recommendation mode unprompted in the middle of a briefing.

Semantics you need to carry

The briefing depends on knowing what each setting actually controls. Short reference:

• auto-publish: whether successful checkin automatically publishes to publish-registry. Off means publishing is manual.
• visibility: default public/private on the target registry. On cg this is a no-op (all cg widgets are public). On other registries, private means invited-only.
• governance: whether community members can propose changes to published widgets. open allows proposals, protected restricts edits to the owner.
• publish-registry: prefix of the registry that receives publishes. Defaults to cg. Custom prefixes route to user-added registries.
• cloud: whether Cartograph queries cloud registries at all. Disabled means library is local-only.
• show-unavailable: whether search includes widgets whose language engine isn't installed here. They surface but can't install until the engine is present.
• auto-update: whether Cartograph nudges the user about new CLI releases.
• paths.<binary>: override PATH lookup for a specific engine binary. Only meaningful when auto-detection fails.

The change loop (both modes)

In Briefing mode: after the three paragraphs, ask "anything here you want to change?" and enter the change loop.

In Recommendation mode: after the user confirms a profile, enter the change loop for the settings the profile changes.

For each change request:

1. Restate the intent in one sentence so the user can correct you.
2. Apply it.
3. Surface any warning the CLI returns (e.g. "visibility is a no-op on cg") without rephrasing — the CLI's wording is the source of truth.
4. Move to the next change.

One change at a time. Don't batch.

Scope

This skill explains what the user has configured. It does not teach the end-to-end publishing workflow, proposal review, or widget-first planning. If the user moves into those areas, let the conversation end cleanly — this skill doesn't follow them there.

What not to do

• Don't read every setting aloud in a briefing; synthesize into the three paragraphs.
• Don't explain what a setting could be unless the user is asking to change it.
• Don't editorialize. State mechanics, let the user decide.
• Don't invent defaults. The config output surfaces them.
• Don't list all four profiles when the user has already named an intent — narrow first.
• Don't apply a profile as an opaque operation. Show the diff (current → new) for each key that changes.
• Don't drift between modes mid-conversation. Briefing stays a briefing; recommendations are opt-in.
