What it does

Negotiation is an agent skill from wondelai/skills. Prepare and execute negotiations using tactical empathy, calibrated questions, and the Ackerman method. Use when the user mentions "salary negotiation", "contract terms", "handling objections", "mirroring and labeling", "difficult conversation", "deal terms", "BATNA", "anchoring", "how do I ask for a raise", "get a better deal", or "they wont budge on price". Also trigger when preparing for a vendor negotiation, resolving a pricing dispute, or navigating a high-stakes conversation where both sides need to feel…

Its SKILL.md is about 4.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/techniques.md`).

The repository describes itself as: Wondel.ai Agent Skills — Business, Marketing, UX & Coding Frameworks from Bestselling Books. 50 skills + 12 guided journeys for Claude Code, Codex, Cursor & other agentskills.io… The licence is MIT.

When your agent uses it

  • The user mentions salary negotiation
  • Handling objections
  • Mirroring and labeling
  • Difficult conversation

Example prompts

  • “salary negotiation”
  • “contract terms”
  • “handling objections”
  • “/negotiation”

What it can do on your machine

Read from SKILL.md and the folder at commit c172996. 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.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • amazon.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

Negotiation loads about 4.7k tokens when it runs, and up to ~8.9k if it reads all its reference files. Until then it costs about 171 tokens; SKILL.md has 2,427 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~171
When it runs · the whole SKILL.md, loaded when a task matches
~4.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.9k

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

Negotiation

Tactical empathy-based negotiation framework from FBI hostage negotiator Chris Voss. Understand the emotional drivers behind decisions and use proven techniques to build rapport, uncover hidden information, and reach better outcomes.

Core Principle

People want to be understood and feel safe. The most effective path to "yes" runs through empathy, active listening, and emotional intelligence -- not logic, arguments, or compromise. Treat every negotiation as a discovery process: your assumptions are hypotheses to test, and the other side's needs (respect, security, autonomy) matter more than their stated positions. Never split the difference -- no deal is better than a bad deal.

Scoring

Goal: 10/10. Score 1 point per satisfied Quick Diagnostic row (6 rows), plus up to 4 points for execution quality: emotions labeled out loud (+1), "That's right" earned not "You're right" (+1), no "Why?" / no splitting the difference / no chasing "yes" (+1), at least one Black Swan surfaced (+1). Bands: 9-10 = audit delivered, calibrated questions and BATNA prepared, "That's right" achieved, Black Swans hunted; 5-6 = some prep but arguing the position or chasing "yes"; <=3 = no audit, no BATNA, splitting the difference. Always state the current score and the specific gaps to reach 10/10.

Framework

1. Tactical Empathy

Core concept: Consciously imagine yourself in the counterpart's situation, then vocalize their perspective to create trust and openness.

Why it works: When people feel understood, brain chemistry shifts toward trust and cooperation, short-circuiting defensive reactions. Empathy is not agreement -- you can understand their position while advocating your own.

Key insights:

  • Before responding, ask: "What is their world like right now?"
  • Articulate their situation, pressures, and fears before stating your position
  • Empathy must be genuine, not performed -- people detect fakeness instantly
  • Unconditional positive regard: respect them as a person regardless of disagreement
  • Emotions are contagious -- stay calm and positive; slow pace enables clear thinking

Product applications:

ContextApplicationExample
Customer supportAcknowledge frustration before solving"I understand this outage is affecting your team's deadline"
Sales callsVoice the prospect's pressures"It sounds like you're under pressure to show results this quarter"
Pricing conversationsAcknowledge budget constraints upfront"I know adding another tool to the stack feels risky right now"

Copy patterns:

  • "I understand you're dealing with..."
  • "It seems like this is creating pressure for your team..."
  • "Before we talk about next steps, I want to make sure I understand where you're coming from..."

See references/techniques.md for the full 21-technique reference -- each section below points to the part you need at the moment you need it. Open it now for The Power of Apology and Pause, which has no section here.

2. Mirroring

Core concept: Repeat the last 1-3 critical words your counterpart said, with a curious, upward-inflecting tone, then go silent.

Why it works: Mirroring signals deep listening, creating familiarity and rapport. It prompts elaboration without direct questions, revealing more than the counterpart intended to share.

Key insights:

  • Repeat the key or emotion-laden words back as a gentle question
  • Wait silently (4+ seconds) for them to expand
  • Works in person, on the phone, and in written communication
  • The simplest technique, but often the most effective for information gathering

Product applications:

ContextApplicationExample
Discovery callsMirror key concerns to get elaborationClient: "The timeline is tight." You: "The timeline is tight?"
User interviewsEncourage deeper explanation of painUser: "It's just frustrating." You: "Frustrating?"
Objection handlingReflect to find the root cause"Doesn't fit your budget?"

Copy patterns:

  • "[Key phrase they used]?" (with question mark)
  • "You mentioned [their exact words]..."
  • "When you say [mirror], what does that look like?"
3. Labeling

Core concept: Identify and verbalize the counterpart's emotions or perspective using neutral phrases: "It seems like...", "It sounds like...", "It looks like..."

Why it works: Naming emotions validates them -- labeling negative emotions diffuses their power, labeling positive emotions reinforces them. The tentative phrasing gives room to correct you, which deepens the conversation either way.

Key insights:

  • Always use third-person phrasing ("It seems like..."), never "I think you..."
  • After labeling, be silent -- let them respond
  • A wrong label still pays: their correction is valuable information
  • Watch for emotional shifts that signal you've hit the mark

Product applications:

ContextApplicationExample
Customer complaintsName the frustration before solving"It sounds like you feel let down by our response time"
Sales objectionsLabel the underlying concern"It seems like there's a concern about implementation risk"
Churn preventionIdentify the real reason for leaving"It sounds like something changed since you first signed up"

Copy patterns:

  • "It seems like..."
  • "It sounds like you're feeling..."
  • "If I'm reading this right, it feels like..."
4. Calibrated Questions

Core concept: Open-ended "How...?" and "What...?" questions that shape the conversation while giving the counterpart the illusion of control.

Why it works: Calibrated questions engage the counterpart's problem-solving mind, making them feel in charge while you steer. They force the other side to consider your position without you stating it, and avoid the defensiveness "Why?" creates.

Key insights:

  • Start with "How" or "What" -- avoid "Why" (sounds accusatory)
  • "How am I supposed to do that?" is the most powerful pushback without saying no
  • Keep the tone genuinely collaborative, never sarcastic
  • Exception for "Why": only when you want them to defend something favorable to you ("Why would you ever choose our company?")
  • Follow every "yes" with "How...?" to secure implementation commitment

Product applications:

ContextApplicationExample
Price negotiationPush back without refusing"How am I supposed to do that at that price point?"
Scope creepMake them own the constraint"What happens to the timeline if we add this?"
Stakeholder alignmentUncover hidden decision-makers"How does your team typically make decisions like this?"

Copy patterns:

  • "How am I supposed to do that?"
  • "What's the biggest challenge you're facing?"
  • "What would it take to make this happen?"

For No-oriented questions ("Would it be unreasonable to...?") and tactical mislabeling to draw out a corrective "No", see techniques.md section 8 when a counterpart is guarded or stalling.

5. Accusation Audit

Core concept: Before negotiating, list and preemptively verbalize every negative thing the counterpart might think or say about you.

Why it works: Naming fears and criticisms before the other side does removes their power -- it often triggers reassurance ("Oh, I don't think that...") and at minimum neutralizes objections. Addressing the elephants first demonstrates self-awareness and builds trust.

Key insights:

  • Brainstorm every negative they might think before the meeting
  • Deliver the audit early in the conversation, not after objections surface
  • Overshoot on purpose -- the list should sound slightly worse than what they actually think
  • Particularly powerful when you're the party with less leverage

Product applications:

ContextApplicationExample
Price increase announcementPreempt anger before explaining"You're probably thinking we don't value your loyalty..."
Sales cold outreachAcknowledge the intrusion"I know you're busy and the last thing you want is another sales pitch..."
Service failure recoveryOwn the failure fully"You're probably furious, and you have every right to be..."

Copy patterns:

  • "You probably think..."
  • "I know this might seem like..."
  • "You might be wondering why you should even listen to..."
6. "That's Right"

Core concept: Summarize the counterpart's position -- facts, emotions, and concerns -- so accurately that they respond with "That's right." This is the breakthrough moment in any negotiation.

Why it works: "That's right" signals the person feels completely understood, shifting their mindset from adversarial to collaborative. It is fundamentally different from "You're right," which usually means they're dismissing you.

Key insights:

  • "That's right" is the two most powerful words in negotiation; if you get "You're right," keep working -- you haven't connected yet
  • Include emotional subtext in your summary, not just facts
  • Let them say "No" first to feel safe, then work toward "That's right"
  • Use the Rule of Three: confirm agreement three times in three different ways

Product applications:

ContextApplicationExample
Sales closingSummarize their needs before proposing"So your team needs X, you're worried about Y, and Z is the deal-breaker..."
Customer retentionShow you understand why they're leaving"Let me make sure I have this: the product isn't delivering on the promise we made..."
Negotiation closureConfirm understanding before terms"Let me make sure I understand: you need [X], by [date], and [constraint]..."

Copy patterns:

  • "Let me make sure I understand..."
  • "If I'm hearing you correctly..."
  • "It sounds like [complete summary of their position including emotions]..."

For the three types of Yes (counterfeit, confirmation, commitment) and the Rule of Three confirmation sequence, see techniques.md sections 10-11 when closing or locking in a commitment.

7. Ackerman Bargaining

Core concept: A systematic monetary negotiation method: calculated offers in decreasing increments (65% -> 85% -> 95% -> 100% of target) with precise non-round numbers and a non-monetary bonus at the end.

Why it works: Decreasing increments signal you're approaching your limit, and precise numbers ($47,235 vs $47,000) feel calculated and final. The closing non-monetary gift signals generosity at the limit, making it psychologically harder to ask for more.

Key insights:

  • Set your target price first, then open at 65% and raise in decreasing increments: 85% -> 95% -> 100%
  • Use precise, non-round numbers on the final offer ($10,230 not $10,000)
  • Attach a non-monetary bonus to the final offer ("...and I'll include X")
  • Never make a concession without getting something in return

Product applications:

ContextApplicationExample
Salary negotiationStructure counter-offers systematicallyTarget $120K: open at $78K, move to $102K, $114K, final $120,350 + extra PTO
Vendor pricingMethodical price reductionTarget $50K: start $32.5K, move to $42.5K, $47.5K, final $49,850 + extended payment terms
SaaS enterprise dealsMulti-year pricing negotiationsDecreasing discount increments across contract years

Copy patterns:

  • "Based on our analysis, we can offer $[precise number]..."
  • "We've stretched as far as we can -- $[precise number], and we'll include [non-monetary bonus]"
  • "I've gone back to my team and the absolute best we can do is $[precise number]"

For setting the opening anchor, soft range-anchoring, and framing loss aversion, see techniques.md section 14 before you name the first number.

8. Black Swans

Core concept: Hidden, game-changing pieces of information that transform a negotiation once discovered. Every negotiation has approximately three lurking.

Why it works: Negotiations stall or fail when critical information stays hidden. Black Swans -- the unknown unknowns -- explain seemingly irrational behavior, and discovering even one can turn a stalemate into a breakthrough.

Key insights:

  • Three types: secret constraints (boss capped the budget), hidden motivations (this deal saves their job), unknown context (a competitor just moved)
  • Watch for anomalies -- odd reactions, hesitations, inconsistencies -- and listen in unguarded moments before and after meetings
  • If they seem irrational, diagnose: ill-informed, constrained, or hiding something?
  • Use all three leverage types -- positive (what they want), negative (what they fear), normative (their own stated values) -- to surface hidden information

Product applications:

ContextApplicationExample
Enterprise salesDiscover hidden budget or timeline constraints"What happens internally if this doesn't get resolved by Q3?"
Churn analysisUncover the real cancellation reason"It seems like something changed -- what happened?"
Hiring negotiationsDiscover the candidate's true priorities"What would make you regret not taking this offer?"

Copy patterns:

  • "What's the biggest thing I'm missing here?"
  • "Help me understand -- what's really driving this?"
  • "What would change everything about this situation?"

For applying the three leverage types, reading pronoun shifts that reveal who really decides, and using dynamic silence to draw out hidden information, see techniques.md sections 16, 20, and 21 when a negotiation stalls or you suspect a hidden decision-maker.

Handling Common Situations

  • They say "That's not fair": Stop immediately: "I want to be fair. Have I done something unfair? Let's discuss it."
  • They anchor with an extreme number: Don't counter; ask "How did you arrive at that figure?"
  • They stop responding: Send "Have you given up on [the project]?" -- triggers a "No" response
  • They seem irrational: Diagnose with calibrated questions: ill-informed, constrained, or hiding something?

Counterpart Styles

StyleSignsAdapt by...
AnalystMethodical, data-driven, hates surprisesUse facts, be patient, don't rush
AccommodatorFriendly, relationship-focused, avoids conflictBuild rapport, but pin down specifics
AssertiveDirect, time-conscious, wants to winBe efficient, stand firm, acknowledge their points

Insight: Great negotiators borrow from all three styles as needed.

Voice and Delivery

  • Default voice: Positive, warm, light-hearted (with a smile)
  • Critical moments: Late-Night DJ Voice -- slow, calm, downward inflection
  • After key statements: Pause 4+ seconds (tactical silence)
  • Watch their nonverbals: 7% words, 38% tone, 55% body language

See techniques.md sections 4 and 19 when you need the full Late-Night DJ Voice mechanics and the cues to read in their body language.

Common Mistakes

MistakeWhy It FailsFix
Splitting the differenceLukewarm outcomes nobody is happy withHold firm; no deal is better than a bad deal
Pushing for "yes"Makes people defensive; produces counterfeit agreementPursue "That's right"; let them say "No" first
