Why your CRM agent pulls the wrong deals

Sep 25, 2026 · 1 min read ·

The MCP can read your deals. It doesn't know what “stalled” means at your company. A skill fixes that in an afternoon.

01 · The symptom
“I asked for stalled deals and it gave me everything closing this month.”
02 · The gap

Why the stock MCP can’t do it

The stock MCP gives Claude a search tool with filters for stage, owner and close date. “Stalled” isn’t one of them. So Claude picks the closest filter it can see, close date this month, and returns everything in it.

You ask:“show me stalled deals” Claude +stock MCP search( close_date: this_month) Every deal closingthis month Missing from the flow:what “stalled” means at your company
You ask: “show me stalled deals” Claude + stock MCP search(close_date: this_month) Returns every deal closing this month Missing from the flow:what “stalled” means at your company
Your question goes to Claude. Claude calls the stock MCP's search with the closest filter it has, close date this month, and returns every deal in it. Your definition of stalled never enters the flow.

Nothing is broken. The MCP answers the question it received. The definition of stalled lives in your head, your pipeline review, or an old Slack thread.

The fix: a skill that knows what stalled means

A skill is a short instruction file Claude loads when the task matches. This one tells Claude what stalled means at your company and points to a reference file with the stage rules.

references/stalled-deals.yaml
# Loaded by the pipeline-review skill. Edit here when stages change.
stalled:
  no_activity_days: 14
  stages: [discovery, proposal, negotiation]
  exclude:
    - close_date_within_days: 7   # closing soon is not stalled, even if quiet

Keep the rules in the reference file, not the skill. When stages change, you edit one file.
