What its author says it does

Copied from the file, not written here

Win/loss analysis for B2B SaaS. Analyzes sales call transcripts across 6 dimensions (product, messaging, GTM/sales, pricing, competition, customer context) to extract why deals are won, lost, retained, or churned. Produces aggregate patterns with verbatim-quote evidence, frequency counts, confidence levels, and strategic recommendations. Includes process steps, output template, quality checklist, extraction patterns, and a worked 5-transcript example.

Win/loss analysis

Analyze sales call transcripts to extract actionable insights on why deals are won, lost, retained, or churned. Cross-reference findings with ICP, firmographics, and competitive context to produce strategic recommendations.

Knowledge type: win-loss-analysis Maturity on first run: emergent → validated after team review


Claude Code triggers

Invoke when user says:

  • "Win/loss analysis"
  • "Analyze sales calls"
  • "Why did we win/lose"
  • "Churn analysis"
  • "Retention analysis"
  • "Sales call insights"
  • "Deal outcome patterns"
  • "Customer feedback synthesis"
  • "Analyze these transcripts"
  • "What patterns in our sales calls"

Do NOT invoke when:

  • User wants general transcript analysis → use a generic transcript skill
  • User wants competitor research → use competitor-research
  • User wants a single customer interview write-up → use a transcript skill
  • User wants sales enablement assets → use a sales-enablement skill

Input requirements

Required

InputDescriptionSource

OutcomeWin/Loss/Retention/Churn for each callUser specifies or infer

Optional (improve quality)

InputHow it helps
Website URL per customerFirmographics cross-reference
Product/ICP documentDefine in-scope product capabilities
Market/GTM documentPositioning and competitive landscape
Sales notes columnAdditional context (stage, deal size)
Competitor namesPre-identify competitors to watch for

Validation

Before proceeding: at least one transcript provided; outcome known or inferable from transcript; customer name identifiable.

If inputs are missing: ask the user for transcripts. Clarify if outcome should be inferred from transcript signals.

Transcript intake — normalize, redact, bind to evidence

Transcripts arrive in many shapes (Gong, Fireflies, Otter, Grain, Zoom/Avoma VTT, SRT, recorder JSON, or plain pasted text). Before Phase 1, normalize whatever you're handed into one shape — speaker-attributed turns with timestamps where present. Two rules apply to every transcript before analysis:

  • Redact PII first. Mask end-client names, emails, and account numbers before processing; keep roles, company, and deal context. (Load-bearing for regulated industries.)
  • Bind every claim to evidence. Every extracted pattern cites a verbatim quote plus the speaker; normalized, speaker-attributed turns make that attribution reliable.

Process

The analysis runs in 3 phases. Read references/process.md for the full step-by-step (4 transcript-processing steps, 4 aggregation steps, 4 synthesis steps, plus per-phase checkpoints and the process flowchart).

Phase summary:

  1. Transcript processing — classify outcome, identify speakers, extract customer context, pull verbatim quotes for the 6 dimensions
  2. Pattern aggregation — group by outcome, count frequency, rank patterns (3+ mentions), cross-reference by ICP/competitor/persona
  3. Insight synthesis — state pattern, provide evidence with frequency + confidence, identify opportunity, generate executive summary

Core frameworks

Analysis modes

ModeWhen to useOutput
Single callDeep analysis of one transcriptFull insight extraction per dimension
Batch analysisMultiple transcripts (3-20 calls)Aggregated patterns with frequency counts
Comparison matrixWin vs. loss OR retention vs. churnSide-by-side pattern comparison

Default to batch analysis mode when multiple transcripts are provided.

6 analysis dimensions

#DimensionWin signalsLoss signals
1Product"Exactly what we need," feature praised"Missing [feature]," "Doesn't do [X]"
2Messaging"Now I understand why this matters""What does it actually do?"
3GTM/Sales"You really understand our problem""Demo didn't address our needs"
4Pricing"Fair price," "good value""Too expensive," "over budget"
5Competition"Chose you over [competitor]""Going with [competitor]"
6Customer context"Need this now," deadline-driven"No rush," "maybe next year"

Confidence scoring

LevelDefinitionWhen to apply

Medium2 calls or inferred from strong signalsEmerging pattern
LowSingle mention or indirect referencePossible outlier

Outcome classification

LossDeal lost to competitor or no-decision"Going with [competitor]," "Not right now"
RetentionExisting customer renewing/expandingRenewal discussion, expansion
ChurnExisting customer leaving/reducingCancellation, "not getting value"

Output

Produce a single win/loss report markdown file. Template + iteration prompts library: references/output-format.md.

Pre-delivery quality checklist + worked example + anti-examples: references/quality.md.

Auto-update protocol (feedback signals, pattern detection, skill-update template): references/auto-update.md.


Anti-hallucination guardrails

  1. Quote verbatim. All insights must trace to specific transcript quotes.
  2. Never invent patterns. If a pattern appears in only one call, label it "Single mention — pattern unconfirmed."
  3. State frequency. Always note how many calls support each finding (e.g., "4 of 7 calls").
  4. Acknowledge gaps. If a dimension has no data, mark "Not discussed in transcripts."
  5. Distinguish roles. Tag who said what — prospect vs. sales rep vs. champion.

Gotchas

  • Correlation as causation. Reports "deals with longer sales cycles were lost" as if cycle length caused the loss → always distinguish patterns from causes. Use "associated with" not "caused by".
  • Small sample bias. Draws conclusions from 2-3 deals instead of waiting for sufficient data → flag sample size prominently. Minimum 5 wins and 5 losses for reliable patterns.
  • Missing verbatim quotes. Summarizes what buyers said instead of extracting exact quotes → verbatim quotes are the primary deliverable. Summaries are secondary.
  • Single-dimension analysis. Only looks at win/loss by competitor, missing dimensions like deal size, ICP segment, or sales cycle stage → cross-tabulate across at least 3 dimensions.
  • Conflates product feedback with sales insights. Mixes "they wanted feature X" with "they didn't trust our team" → separate product gaps from sales execution issues. They feed into different downstream work.

Data integration

Level: 0 — Context (heavy pulls)

If you run win/loss inside a connected environment, pull transcripts and deal context fresh:

SourceWhat to pullWhen
Meeting recorder (Granola, Gong, Fireflies, etc.)Sales call transcripts and deal discussionsAlways
Team chat (Slack, etc.)Deal discussion threads and competitive intelAlways

Fallback (no integrations): user-provided call transcripts or recordings; manual deal review notes.
