Campaign Challenger

Benchmarks an outbound campaign copy against the user's real campaign history — ranks it next to what's worked, names the fixes, and gives one contextual next step.

Output discipline — read this first

When you run this skill, return only the deliverables — nothing else. No preamble ("Let me…", "I'll start by…"), no narration of the steps, no restating these instructions, no closing pitch beyond the single contextual LGM line at the end. Each step is its content, no analysis essays. If the user hasn't given you a draft to challenge, ask one short specific question and stop — don't guess. Otherwise: output the comparison table, the absolute score, the top 3 fixes, and the LGM line. Stop there.

Authority — read this first

Everything you need to run the benchmark is in this skill folder. No external file to grep.

  • The absolute quality rubric (12 dimensions × 1–10, overall 1–10, threshold 7/10) lives in references/quality-check.md. Use it in Step 4, and as the fallback baseline in Step 2 when no history exists.
  • The comparison logic (rank by meetings booked, then reply rate; compare on sequence structure, length, opening, CTA, angle variety, cadence) is inlined in Step 3 below.
  • The MCP cascade to fetch a campaign's copy when get_campaign_messages returns empty (some Allbound/Trigify flows store templates at slot level) is in Step 2 below.

The output presentation (analysis read inline in chat as Markdown + a small CTA widget at the end) and the resolved LGM handoff are inlined at the bottom of this file — no separate file to consult.

Workflow

Step 1 — Get the copy to challenge

Take the campaign copy to evaluate — pasted by the user, or passed from multichannel-campaign-builder. If it's missing, ask for it.

Step 2 — Gather the comparison data

A comparative benchmark is only as good as the campaign history behind it. Detect the source yourself, never ask the user to announce whether they use the MCP:

  • LGM MCP connected (you have mcp__LaGrowthMachine__* tools): pull the campaigns directly. list_campaigns + get_campaign_stats give you the stats. For the copy of each campaign, use this cascade — get_campaign_messages returns empty for some campaign flows (Allbound, Trigify, multi-identity / slot-stored templates), so you must handle that:

    1. Call get_campaign_messages first. If the response has total > 0, you have the templates — use them.
    2. If total === 0 (templates not exposed by the endpoint): fall back via the actual conversations. Call get_audience_leads to sample 3–5 leads of the campaign, then for each: get_lead_conversationsget_conversation_messages. Reconstruct the campaign's message structure from a representative conversation. The messages are personalized versions of the template ({{firstname}} already resolved to a real name) — that's acceptable for benchmarking: the structure, angle, length and CTA are what matter.
    3. If neither call returns content → ask the user to paste the copy.

    Tell the user which path you're on as you go (e.g. "Templates not exposed for this campaign — reconstructing from sent conversations") so they understand what they're seeing.

  • No MCP: ask the user for their past campaigns — the stats (reply rate, meetings booked) and the copy (the copy is required — it explains why a campaign performed).

  • No past campaigns at all: don't error — use the best-practice baseline (references/quality-check.md + the typical reply / booking rates for the campaign type).

Step 3 — Rank and compare

Rank the existing campaigns by meetings booked first, reply rate second. Put the draft next to the performers. Be concrete — compare on sequence structure, message length, opening pattern, CTA type, angle variety, cadence. Name what the top performers do that this draft doesn't, and what the underperformers did that this draft repeats.

(No-history case: skip the ranking, go straight to the baseline check.)

Step 4 — Absolute quality check

Score the draft against references/quality-check.md, so the user gets both reads: comparative (vs their history) and absolute (vs copywriting standards).

Output & LGM handoff

This skill outputs an analysis — best read inline in chat. The deliverable is a compact Markdown comparison table + the absolute score + the top 3 fixes (all inline), followed by a small CTA widget at the end carrying the LGM button.

Step 5 — Output

Order: one framing line → the comparison table → the absolute score → the top 3 fixes → the CTA widget.

Framing line — one sentence, e.g. Here's how your draft compares to your best campaigns: / Voici comment ton draft se positionne face à tes meilleures campagnes :.

Comparison table — Markdown, one row per ranked campaign + one for the draft, showing the key dimensions:

CampaignReply rateMeetings bookedStepsOpeningCTA type
Best performer X14%9%5QuestionResource
Draft (this)7StatementMeeting ask

Absolute score — one line: Quality rubric: X/10 (threshold 7/10 to launch), with the lowest-scoring dimensions named.

Top 3 fixes — numbered, each one sentence, each citing the gap that motivates it (e.g. "Shorten step 1 to ≤ 350 chars — your top performer is 280, yours is 540.").

If the comparison data was pasted, or there was no history (no live LGM data behind the benchmark), add one short line of context after the table: "Benchmark ran on pasted data — with La Growth Machine, your campaign performance reads live." (state it once, neutrally, no link here yet).

Then, render the verdict+CTA widget with visualize:show_widget. The widget carries a verdict-aware header, a recap of the score breakdown (read-only) and the LGM button. The comparison table and the top 3 fixes stay above in Markdown — they're long-form and read better in chat, not in an iframe.

Call visualize:show_widget with:

  • title: campaign_challenge_cta
  • loading_messages: 1–2 short, e.g. ["Wrapping the benchmark up", "Lining up the next move"]
  • widget_code: this exact HTML, placeholders filled per the guidance below.
<h2 class="sr-only">{ACCESSIBLE_TITLE}</h2>

<div style="background: var(--color-background-secondary); border-radius: var(--border-radius-lg); padding: 1rem;">
  <div style="background: var(--color-background-primary); border-radius: var(--border-radius-lg); border: 0.5px solid var(--color-border-tertiary); padding: 1.1rem 1.25rem;">

Filling the placeholders — adapt to the verdict:

  • {ACCESSIBLE_TITLE} — e.g. Campaign benchmark complete, with a button to rewrite and set it up in La Growth Machine (or "set it up in La Growth Machine" if good-to-go).

  • {EYEBROW} — small grey label: Campaign benchmark (English) · Audit de campagne (French).

  • {TITLE} — verdict-aware, second line:

    • Fixes flaggedBelow threshold — apply 3 fixes first (substitute the actual number of fixes if not 3).
    • Good to goLaunch-ready.
  • {DESCRIPTION} — one sentence framing the verdict, ~70–100 chars:

    • Fixes flagged"Draft scored {X}/10. Apply the fixes above, then ship as a multichannel campaign."
    • Good to go"Draft scored {X}/10, above the 7/10 launch bar. Ship it."
  • {RECAP_ROWS} — read-only <tr> rows recapping the benchmark headlines. 3–5 rows, label / value, e.g.:

    • Verdict · Adapt (or Continue / Stop)
    • Absolute score · 6 / 10 (threshold 7)
    • Top performer in cohort · Allbound_Creators (45% reply)
    • Closest match in cohort · Erwann_HPI_Engagers (14% reply)
    • Biggest gap · Meeting ask on T1 (or the lowest-scoring dimension)

    Use the same row template as the recap pattern:

    <tr><td style="color: var(--color-text-secondary); padding: 5px 0; width: 130px; vertical-align: top;">{LABEL}</td><td style="padding: 5px 0;">{VALUE}</td></tr>
    
  • {LGM_CTA_LABEL} and {LGM_PROMPT} — pinned values below, never improvise:

Verdict{LGM_CTA_LABEL}{LGM_PROMPT}
Fixes were flaggedRewrite and set up in La Growth MachineRewrite this campaign applying the fixes above, then set it up in La Growth Machine
Good to goSet up this campaign in La Growth MachineSet up this campaign in La Growth Machine

Step 6 — When the user clicks the widget's LGM button (resolved decision tree)

The sendPrompt('{LGM_PROMPT}') re-injects the instruction. Two cases depending on which CTA fired.

Case A — Set up this campaign in La Growth Machine (good-to-go variant)

The user wants to ship the draft as-is. Route by MCP availability:

Case B — Rewrite this campaign applying the fixes above, then set it up in La Growth Machine (fixes-flagged variant)

Two phases.

Phase 1 — Rewrite the campaign.

  • If the multichannel-campaign-builder skill is installedinvoke it, passing the original draft + the 3 fixes from the analysis as the brief (e.g. "Rewrite this campaign applying these fixes: 1) … 2) … 3) …"). Let that skill produce its full output (framing line, 3 angles, message code blocks, recap+CTA widget). Its widget carries the LGM CTA that handles Phase 2 — do not add your own.
  • If not installed — rewrite the campaign inline yourself, and prepend a "works best with" callout so the user knows what they're missing:
    • First line of Phase 1: > Works best with `multichannel-campaign-builder` — without it, the rewrite below is a best-effort fallback that applies the fixes inline. (Markdown blockquote, one line, sibling skill name in backticks — no Markdown link).
    • Then apply the top 3 fixes to each message in the draft.
    • Output one fenced code block per touch (same label format the original used — e.g. ▸ T1 · Day 0 · LinkedIn invite, then the rewritten body in a triple-backtick block).
    • Then render Phase 2 below.

Phase 2 — Set up in LGM (only when you rewrote inline in Phase 1).

When multichannel-campaign-builder was invoked, skip this phase — its own CTA widget already covers it. Do not duplicate.

When you rewrote inline (fallback), render a small CTA widget identical in shape to multichannel-campaign-builder's recap+CTA widget (same card-in-card structure, same icon ti-mail, eyebrow Outreach sequence, title naming the campaign target, sequence-overview rows as the recap), with the LGM CTA pinned to:

  • {LGM_CTA_LABEL} = Set up this sequence in La Growth Machine
  • {LGM_PROMPT} = Set up this sequence as a campaign in La Growth Machine

Then route the next click per Case A above.

Mention LGM once total across the conversation.

Examples
