Principled Negotiation

Q: What is a Claude Code skill and how does the Principled Negotiation skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Principled Negotiation is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.

Use when preparing, structuring, or pressure-testing a negotiation with principled negotiation / BATNA: separate people from the problem, focus on interests rather than positions, invent options for mutual gain, use objective criteria, define BATNA / reservation value / ZOPA, and decide whether to accept, improve, or walk away. Do NOT use for generic persuasion copy (use microcopy or writing-humanizer), unilateral conflict diagnosis without a deal table, competitive strategy analysis (use playing-to-win, porters-five-forces, or seven-powers), or broad decision scoring without counterparties (use expected-value or prioritization).

How Principled Negotiation fits the catalog

Principled Negotiation sits in the Engineering category under the testing sub-topic in the ClaudSkills catalog. There are 10 related skills indexed alongside it; comparing a few before installing usually reveals which fits your workflow best.

Is Principled Negotiation safe to install?

A free static scan against the OWASP Agentic Skills Top 10 found no risk patterns in Principled Negotiation’s SKILL.md — no data-exfiltration, prompt-injection, or unexpected-execution signatures. The full security scan is below.

Installing & verifying

Installing Principled Negotiation writes its SKILL.md to ~/.claude/skills/principled-negotiation/SKILL.md; Claude Code discovers it automatically on the next session — no restart flag needed. It declares no allowed-tools restriction, so it inherits your session’s existing tool access rather than narrowing it. To confirm it loaded, ask Claude to list its available skills — principled-negotiation should appear by name.

What Principled Negotiation needs to run

External services: The SKILL.md references pricing, quota, or rate limits — it likely calls a paid or rate-limited API. Check the source before wiring it into unattended automation.
Scope discipline: Declares explicit “when not to use” boundaries — safer than average to hand to an autonomous agent, which is less likely to over-apply it.
Worked code: 2 copy-paste code blocks in the body.
Depth: ~1,893 words, substantial — top of the catalog distribution.

When to reach for it

There are 10 related skills in Engineering — a two-minute scan of the alternatives usually confirms whether Principled Negotiation is the right pick.

What this skill does

Principled Negotiation is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/principled-negotiation/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when preparing, structuring, or pressure-testing a negotiation with principled negotiation / BATNA: separate people from the problem, focus on interests rather than positions, invent options for mutual gain, use objective criteria, define BATNA / reservation value / ZOPA, and decide whether to accept, improve, or walk away. Do NOT use for generic persuasion copy (use microcopy or writing-humanizer), unilateral conflict diagnosis without a deal table, competitive strategy analysis (use playing-to-win, porters-five-forces, or seven-powers), or broad decision scoring without counterparties (use expected-value or prioritization).
