What it does
Battle Card Builder is an agent skill from deanpeters/Product-Manager-Skills. 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.
Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `examples/sample-industrial.md`, `examples/sample.md` and `template.md`).
It sits in Research & Science, covering Deep research. The repository describes itself as: Product Management skills framework built on battle-tested methods for Claude Code, Cowork, Codex, and AI agents.
When your agent uses it
- A rep needs a field-action card
- Not a research report
Example prompts
- “/battle-card-builder”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Check session for existing evidence — a competitive snapshot or watch report. If present, use
- Credit inline context, then ask only the unanswered questions (max 3)
- If researching fresh, show the 3-bullet search plan — what you'll check (pricing pages,
- Draft the card in the schema below exactly — cards are diffable across runs, and the watch
What it can do on your machine
Read from SKILL.md and the folder at commit 1b5a524. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Battle Card Builder loads about 2.6k tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 1,061 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,061 words (~2,570 tokens).
“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…”
