Concise Output Skill for Claude
Enforces brevity and signal-over-noise in all outputs. Eliminates verbose explanations, filler phrases, and unnecessary elaboration. Triggers on: every response (governs output length and density when loaded).

13 sections, as written by the authorConcise Output
Enforce extreme brevity and high signal-to-noise ratio in all outputs.
Core Principle
Signal over noise. Every word must justify its existence. If it doesn't add essential information, delete it.
Rules
Documentation & Artifacts
- Maximum density: Pack maximum information into minimum words
- No filler phrases: Cut "As we discussed", "It's important to note", "Additionally"
- Bullet lists over paragraphs: Use bullets unless prose is genuinely clearer
- Active voice, present tense: "Run tests" not "You should run the tests"
Conversational Output
- Get to the point: No preambles like "I'll help you with that"
- No meta-commentary: Don't announce what you're about to do
- Cut repetition: Don't restate what the user just said
- Assume competence: User doesn't need hand-holding
Anti-patterns
❌ Verbose:
It's important to note that before we begin the implementation,
we should take a moment to carefully consider the architectural
implications of our approach. Let me explain what I'm thinking...
✅ Concise:
Architectural concern: [specific issue]. Recommend [specific approach].
❌ Verbose:
## Installation Instructions
To install this package, you'll need to follow these steps carefully:
1. First, make sure you have Node.js installed on your system
2. Next, navigate to the project directory using your terminal
3. Then, run the following command to install dependencies:
✅ Concise:
## Install
npm install
❌ Verbose:
I notice that you've made some interesting changes to the authentication
system. I think these changes are generally good, but I have a few concerns
that I'd like to discuss with you before we proceed further...
✅ Concise:
Auth changes look solid. Three concerns: [1], [2], [3].
Context Awareness
When detail IS appropriate:
- Error analysis requiring step-by-step reasoning
- Debugging complex issues
- Teaching fundamental concepts user hasn't seen
- Explaining trade-offs between multiple valid approaches
When brevity is mandatory:
- READMEs, documentation, guides
- Commit messages, PR descriptions
- Implementation plans
- Status updates
- Most conversational responses
Integration with Other Skills
Works well with:
- tdd-process: Keep cycle documentation minimal
- critical-peer-personality: Reinforces professional, no-fluff communication
- Any system prompt: Universal applicability

## Getting Started
Welcome to our project! We're excited that you're interested in using
this tool. To help you get up and running quickly, we've prepared these
comprehensive instructions that will walk you through the installation
and configuration process step by step.
### Prerequisites
Before you begin, please make sure you have the following installed:
- Node.js version 18 or higher
- npm or yarn package manager
...
✅ Concise:
## Quick Start
Requires Node.js 18+.
npm install
npm test
npm start
Commit Message
❌ Verbose:
I've added a new validation system that will help us ensure data
integrity across the application. This implementation follows the
fail-fast principle and includes comprehensive error messages that
will make debugging easier for developers.
✅ Concise:
Add fail-fast validation with explicit error messages
Prevents invalid data propagation at domain boundaries.
Implementation Plan
❌ Verbose:
Okay, so I've thought about this carefully and here's what I think
we should do. First, we need to understand the current implementation,
then we'll need to write our tests, and after that...
✅ Concise:
Plan:
1. Trace current auth flow (src/auth/handler.ts)
2. Write failing test for OAuth integration
3. Implement OAuth handler
4. Refactor duplication in token validation
Summary
Ruthlessly eliminate words that don't carry information. Assume reader competence. Prefer structure over prose. Show rather than explain.

Integration with protocols.io API for managing scientific protocols. This skill should be used when working with protocols.io to search, create, update, or publish protocols; manage protocol steps and materials; handle discussions and comments; organize workspaces; upload and manage files; or integrate protocols.io functionality into workflows. Applicable for protocol discovery, collaborative protocol development, experiment tracking, lab protocol management, and scientific documentation.
Analyzes job descriptions and generates tailored resumes that highlight relevant experience, skills, and achievements to maximize interview chances
Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.
Build and distribute Expo development clients locally or via TestFlight
Use when you have a written implementation plan to execute in a separate session with review checkpoints
Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.
Benchling R&D platform integration. Access registry (DNA, proteins), inventory, ELN entries, workflows via API, build Benchling Apps, query Data Warehouse, for lab data management automation.
Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.
How to use it
Take ntcoding/concise-output from the repository into ~/.claude/skills for personal
use, or into .claude/skills inside a project.
The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
The instructions reference npm.
Without those the skill loads but fails at the first command.
