AUTO-TRIGGER: Apply this skill when the user wants to run, structure, or improve a win/loss analysis program. Trigger phrases include: "win/loss analysis," "why are we losing deals," "why do we win," "lost deal analysis," "closed lost reasons," "competitive losses," "deal debrief," "why did we lose to [competitor]," "what does sales say about why we lose," "our closed lost data is useless," "I want to interview lost prospects," or any situation where the user is trying to understand the…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Win/Loss Analysis: The Diagnostic That Improves Everything Downstream
This skill structures a win/loss analysis program that actually changes
how the team goes to market. Most companies do some version of win/loss
analysis. Almost none do it in a way that produces findings specific
enough to act on.
The failure mode is familiar: CRM closed/lost reason fields that contain
nothing useful ("not the right time," "went with competitor," "budget"),
post-loss debrief conversations with the sales rep that produce the rep's
perspective rather than the prospect's, and quarterly summaries that
confirm what leadership already believed rather than revealing something
that changes a decision.
This skill encodes the practices that produce findings specific enough
to change ICP definition, adjust messaging, inform pricing, and redirect
channel investment. The analysis is only useful if it feeds back into
something that changes.

## HOW TO SET UP THIS SKILL
Provide:
- What data you currently have on lost deals: CRM closed/lost reasons,
rep debrief notes, anything else
- Whether you have access to lost prospects for direct interviews
- The time period you want to analyze

How to install
mdr add modest-curator478/claude-skills/win-loss-analysis@sha256:23adfe5f4c087ea4The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
