This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 24, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

Ran the same Linear-vs-Jira battlecard with and without the skill: the no-skill version stated Jira's price as fact from memory, while the skill forced it to [CONFIRM: pricing]/UNVERIFIED and added a Landmines section of pointed discovery questions plus an honest when-we-lose block. Four sections became ten, and the anti-hallucination guardrail is the real differentiator for a live call.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 7/10
  • Docs & honesty 5/5

What Battlecards does

Generates a structured 10-section competitive battlecard (quick facts, when-we-win/lose, counter-positioning, landmines, objection handling, red flags) for live sales calls. Triggers on "battlecard", "competitive intel", or "how do we beat [competitor]". Enforces source citations and confidence levels so reps don't repeat guessed pricing.

How to install Battlecards

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.

Commands — how to trigger Battlecards

  • /battlecards Competitive sales battlecards with landmines, confidence tags, and anti-hallucination guards

It also activates on plain-language prompts like these:

  • Build a battlecard for how we beat Competitor X in deals
  • I need competitive intel with landmines and objection handling
  • Create a when-we-win/lose card for our top rival
