Prepare, review and debrief negotiations using Luís Almeida Costa's public approach to evolving relationships, critical information, linked packages and conflict prevention. Use for client, supplier or internal bargaining, especially repeated dealings.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Negotiation Strategy and Negotiation Dynamics Based on Luís Almeida Costa's public method. Not affiliated with or endorsed by Luís Almeida Costa. ## When to use Use this skill to prepare a negotiation brief, review proposed terms, diagnose an impasse or debrief a round with clients, suppliers or internal departments. It is particularly useful when today's agreement, unilateral decisions and behavior change tomorrow's options, information or willingness to cooperate. The deliverable is an actionable brief and, after a round, an updated relationship record. [S2] Diagnose the situation before selecting tactics. A competitive bid, a price discussion, a complex package and a repeated relationship need different analysis. Do not promise that every disagreement admits a mutually beneficial deal, or that a courteous process requires accepting unfavorable terms. [S3][S5] …

How to install
mdr add getedgehq/skills/costa-negotiation-dynamics@sha256:82f114c520c6eb47The line at the top of this page pins the label git:20261002.d5668a9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
