⚠ 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.
