Google Ads — Router

The single entry point. Find out where the user is in the campaign lifecycle and hand off to the right sub-skill. Enforce the order so nothing runs on a broken foundation.

STEP 0 — Locate context

Look for account-context.yaml in the working directory (or a --context <path> the user gives).

• Missing → run claude-google-ads:setup first. Nothing else runs without context.
• Present → continue.

STEP 0b — Connection precheck (REQUIRED — don't run skills on a half-connected account)

Read the context connections block (or detect live). Before routing, confirm the prerequisites are set up; the suite's value depends on real data, and it must never run on a gap silently (see the no-fabricate gate):

If Google Ads is missing → stop and run setup. If a value-tier source (store/Merchant/GA4) is missing → surface a one-line "connect these for full value" banner with the how-to, then proceed at reduced scope — every output that needed the missing source is flagged UNVERIFIED, never fabricated. Don't quietly skip.

STEP 1 — Assess lifecycle stage

Run the context validator to read readiness, and scan the working dir for prior artifacts:

python ${CLAUDE_PLUGIN_ROOT}/skills/setup/scripts/validate_context.py ./account-context.yaml

Map state → the next sensible step:

STEP 2 — Route by intent

If the user named a task, map it and dispatch:

• "audit / score / what's wrong / wasted spend" → audit
• "tracking / conversions / GA4 import / double count" → measurement
• "plan / budget / what campaigns / media plan / forecast" → plan
• "build pmax / performance max" → builder-pmax
• "build search" → builder-search
• "branded / brand campaign / conquesting" → builder-branded-search
• "demand gen / youtube / discovery" → builder-demand-gen
• "push / export / upload / go live" → pusher
• "how's it doing / pacing / learning phase / anomaly" → tracker
• "optimize / improve ROAS / negatives / raise tROAS / weekly review" → optimizer
• "experiment / A/B / split test" → experiments
• "ad copy / headlines / assets / creative" → assets If ambiguous, ask ONE clarifying question, then route.

STEP 3 — Full launch (when the user wants the whole thing)

For "set up Google Ads for my business", run the pipeline in order, pausing for input where needed:

setup → measurement [GATE] → audit → plan → builder-* → pusher [approval] → tracker → optimizer

Hard gates (never skip):

• No plan/build before measurement passes (FAIL blocks; WARN carries a risk note).
• build-ready wants brand_terms (for branded search + PMax exclusion).
• pusher always: create PAUSED, human approval, spend cap.

STEP 4 — "Where am I?" summary

When the user just says /google-ads (no task), produce a short status: readiness, what artifacts exist, and the single recommended next action — then offer to run it. Don't dump everything; point to the next step.

Model dispatch (run cheap, decide expensive)

Spend compute by cognitive load, not by habit — see ${CLAUDE_PLUGIN_ROOT}/references/model-tier-dispatch.md. The router itself is Judge (J) work (lifecycle reasoning, routing, gates). But the heavy collection each sub-skill needs is Scout/Routine — so as orchestrator, push it down:

• Scout (S, haiku) — the validate_context.py run in STEP 1, a single status pull, one URL check.
• Routine (R, sonnet) — assembling the active-campaign set, full data-bundle pulls for audit/optimizer/tracker.
• Judge (J, main session) — picking the next lifecycle step, all gates, the "where am I" call. Delegate S/R via Agent(subagent_type: "general-purpose", model: …) so the sub-agent keeps MCP + Bash; tell it to return raw, not conclude. Each sub-skill carries its own per-STEP tier table.

Notes

• The router orchestrates; each sub-skill reads the same account-context.yaml and writes to the working directory. Business data never lives in the plugin — it stays in your local account-context.yaml.
• One working folder per business; nothing scattered. All context + outputs live under a single <workdir> with dated subfolders, and secrets are recorded as POINTERS (not copied) — see ${CLAUDE_PLUGIN_ROOT}/references/workspace-layout.md. If there's no working folder yet, setup creates it.
• Sub-skills are invoked by their namespaced names (claude-google-ads:setup, claude-google-ads:audit, …).
