Pricing Negotiation History
Prerequisites
This skill needs the iGPT MCP at https://mcp.igpt.ai/.
If the MCP tools aren't available or return an auth error, tell the
user to install the iGPT plugin (/plugin marketplace add igptai/skills)
or add https://mcp.igpt.ai/ as a connector, then complete OAuth and say
"ready". Retry once after they confirm. Never invent tokens or OAuth URLs.

What This Skill Does
Traces all pricing conversations with a specific vendor through email history —
every price point discussed, discount or concession offered, counter-proposal
made, final price agreed, and any commitments around future pricing — to build
a complete negotiation dossier for the next pricing conversation.
Workflow
-
Before calling any tool, collect these values from the user. Do not
invent values they did not give.
- [vendor] — the vendor to reconstruct pricing history for. No default
— must come from the user.
- [time_range] — what window of email to scan. The user may give this
in any form ("last 24 months", "the last 2 years", "May 2024",
"since the master agreement"). Default: the last 24 months. Keep
the user's natural phrasing for use in the ask input; convert to
ISO dates separately for the search call.
-
Call search with:
- query: price quote discount offer negotiate reduce concession proposal
rate per unit cost [vendor]
- date_from: ISO start date derived from [time_range]
- date_to: ISO end date derived from [time_range] (or today if open-ended)
-
Call ask with:
- input: Review all email threads with [vendor] from [time_range]. Reconstruct the complete pricing negotiation history: every price quoted, discount or concession offered by either side, counter-proposals made, final prices agreed, volume commitments tied to pricing, any pricing commitments made about future rates, and any language suggesting pricing flexibility or firmness. Note patterns that could inform the next negotiation.

-
Present the summary and current agreed pricing first, then negotiation
insights, then the chronological event history. Lead with the top
negotiation insight and any upcoming repricing opportunity.
-
Ask: "Would you like me to draft a negotiation opening email or prepare
a pricing counter-proposal based on this history?"
