Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00124 | $0.05961 |
| Opus 5.5 | $0.00050 | $0.02384 |
| Sonnet 5.5 | $0.00025 | $0.01192 |
| Haiku 4.5 | $0.00012 | $0.00596 |
Grade A, and why
competitive-battlecard scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 248 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Competitive Battlecard
A battlecard is read once, five minutes before a call, and quoted from memory in the call. This skill builds that one page for one competitor in one deal: what to say first, what to ask, what to say when the buyer pushes back, when to lean in and when to walk away. It does not research the market or map alternatives; it takes the alternatives map and the proof registry already in your brain, adds fresh evidence about the named competitor, tailors the result to who is selling to whom at what stage, and proposes what it learned back into brain Section 3 for you to confirm.
Trigger
- When: A seller or PMM needs a competitor-specific play for a live or upcoming deal, or a refresh of an existing card.
- Not for: Mapping who buyers compare you to →
alternatives-map. A weekly read on what changed →signal-monitor. Registering or checking a claim →proof-points. A feature-level handoff doc with one comparison →product-messaging-playbook. Persona cards and a competitive playbook as part of a positioning build →positioning-messaging(SALES-ENABLEMENT mode). A multi-skill competitive program →workflow-orchestrator. - Example prompts:
- "Battlecard for [competitor]"
- "How do we beat [competitor] with a CFO in the evaluation stage?"
- "[Competitor] is in my deal, what do I say?"
- "They say [claim]. How do I counter it?" (edge: one objection, answered from the card's blocks)
- "Refresh the [competitor] card" (edge: compares with the last saved card)
Inputs
- Args: The competitor (required; doing nothing or a spreadsheet counts). Optional: role, GTM motion, the competitor's status in the deal, buyer persona, deal stage, segment and region, what the buyer actually said, delivery format (Google Doc or HTML). Missing items are asked once in Step 2.
- Defaults: Role account executive, buyer general, stage evaluation, competitor a challenger alongside us, delivery Google Doc. A skipped answer is stated as an assumption on the card.
- Context keys:
/foundation/brain.md(optional, sharper with it): Sections 1 to 8, see the contract./foundation/me.md(optional): format and detail only./foundation/gaps.md(append only)./context/battlecards/(earlier cards for this competitor),/context/signals/(recentsignal-monitorruns),/context/meta-patterns.md(guardrails).~~CRM,~~call recordings,~~competitive intelligence,~~win/loss,~~team chat,~~reviews,~~market data,~~company data,~~knowledge base,~~cloud storage, or pasted material.- Brain contract: Reads: Section 1 (permitted claims, offerings, glossary), 2 (persona, economic buyer, champion, pains, triggers, anti-persona), 3 (alternatives, status quo, why they leave, unique capabilities,
alt_shortfalls,switching_forces,objectionswith approved responses, and the Alternatives Map block for this competitor), 4 (language preferences, forbidden phrases,customer_phrases), 5 (why now), 6 (approved metrics, approved quotes, forbidden claims), 7 (priorities), 8 (prohibited, approvals, stakeholders). Writes: Section 3 only, as one appended Battlecard Field Notes block or a one-line stub, after you confirm the exact text. Never writes to: Sections 1, 2, 4, 5, 6, 7, 8.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

competitive-battlecard is a skill published in the GitHub repository stefanoskarakasis/Product-Marketing-Skills (7 stars, last pushed yesterday), licensed MIT. It adds 124 tokens to every session and 5,961 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-13.
