Research and draft a competitive battle card from public evidence — every claim labeled and sourced. Use when a rep needs a field-action card, not a research report.
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
# Battle Card Builder ## Purpose Build a field-action competitive battle card from public evidence: **use or gather evidence → search plan (if gathering) → draft card with per-claim labels → appendix → next-step options.** A battle card is the artifact a rep opens mid-deal, not a research report — it must fit thirty seconds, every claim must survive being said out loud to a hostile audience, and every claim therefore carries a source URL, a date, and a Fact/Inference/Assumption label. Most battle cards in the wild are unlabeled inference; this skill exists because of what it costs a rep when one of those turns out wrong. ## Input **Works best with:** your product and its primary differentiation, and **the one competitor** this card targets. **Also useful:** the deal context (segment, buyer, common objections or the loss reason that triggered this card), and any [`competitive-research-snapshot`](../competitive-research-snapshot/SKILL.md) or [`competitive-intel-watch`](../competitive-intel-watch/SKILL.md) output in session — the skill uses existing evidence and searches only for gaps and anything older than one quarter. …

How to install
mdr add ninjasln-labs/agent-skills/battle-card-builder@sha256:a2f5e62a7925671fThe line at the top of this page pins the label v1.1.1, 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.
