Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/trkbt10/indexion-skills --skill indexion-segment- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads indexion-segment automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
Security audits
Independent scans of the skill's instructions and bundled files.
SKILL.md
The instructions your agent reads when the skill is triggered.
indexion segment
Split text into contextual segments using divergence-based, TF-IDF, or punctuation strategies.
When to Use
- User needs to chunk text for RAG or embedding pipelines
- User wants to split a document into meaningful sections
- User asks to segment text for processing
- Preparing text for similarity analysis at sub-document level
Usage
# Default window divergence strategy
indexion segment <input-file> <output-dir>
# TF-IDF based segmentation
indexion segment --strategy=tfidf <input-file> <output-dir>
# Punctuation-based segmentation
indexion segment --strategy=punctuation <input-file> <output-dir>
# Custom segment sizes
indexion segment --min-size=200 --max-size=3000 --target-size=800 document.txt output/
# Custom divergence threshold
indexion segment --threshold=0.5 document.txt output/
# Adaptive threshold mode (default)
indexion segment --adaptive document.txt output/
# Hybrid NCD+TF-IDF mode
indexion segment --hybrid --ncd-weight=0.6 --tfidf-weight=0.4 document.txt output/
# Custom window size
indexion segment --window-size=5 document.txt output/
# Custom output prefix
indexion segment --prefix=chunk document.txt output/

--prefix=NAME | segment | Output file prefix |
Strategies
| Strategy | Description |
|---|---|
window (default) | Sliding window divergence detection |
tfidf | TF-IDF based topic change detection |
punctuation | Punctuation/sentence boundary based |

FAQ
What does the indexion-segment skill do?
Split text into contextual chunks for RAG/embedding pipelines. Document segmentation and section extraction using window, tfidf, punctuation, or hybrid strategies chosen by intent.
How do I install indexion-segment?
Run npx skills add https://github.com/trkbt10/indexion-skills --skill indexion-segment in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/indexion-segment/ (personal) or .claude/skills/indexion-segment/ (project).
Which AI agents can use indexion-segment?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is indexion-segment safe to install?
Security partners have reviewed it: Gen Agent Trust Hub passed; Socket passed; Snyk passed. As with any skill, read the SKILL.md and bundled scripts before installing.
Who maintains indexion-segment?
It is published by trkbt10 in trkbt10/indexion-skills. It has 4,921 recorded installs.

Popular ai & agents skills
google-agents-cli-publish
google/agents-cli
This skill should be used when the user wants to "publish an agent", "publish my ADK agent", "register an agent with Gemini", "publish to Gemini" (formerly Gemini Enterprise), or needs guidance on the agents-cli publish gemini command. Also use when the user wants to "manage agents in Agent Registry", "list/update/delete registered agents", or "register an MCP server". Covers ADK vs A2A registration modes, programmatic and interactive usage, flag reference, auto-detection from deployment metadata, Agent Registry fleet management, and troubleshooting. Part of the agents-cli skills suite. Do NOT use for deployment (use google-agents-cli-deploy).
google-agents-cli-eval
google/agents-cli
This skill should be used when the user wants to "run an evaluation", "evaluate my agent", "evaluate my ADK agent", "write an eval dataset", "analyze eval failures", "compare eval results", "optimize agent", or needs guidance on the Gemini platform eval methodology and the Quality Flywheel. Covers eval metrics, dataset schema, LLM-as-judge scoring, and common failure causes. Applies to any agents-cli project, whatever framework the agent is written in. Do NOT use for agent API code patterns (ADK: use google-agents-cli-adk-code), deployment (use google-agents-cli-deploy), or project scaffolding (use google-agents-cli-scaffold).
skill-creator
anthropics/skills
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
codex-pet
prime-skills/runcomfy-agent-skills
Codex Pet generator on RunComfy. Build a Codex-compatible Codex Pet spritesheet.webp + pet.json from a single reference image, drop it into ${CODEXHOME:-$HOME/.codex}/pets/ / and Codex picks it up as a custom Codex Pet next to the 8 built-ins. This skill produces the exact Codex Pet atlas Codex expects (1536x1872 PNG/WebP, 8 cols x 9 rows, 192x208 cells, 9 animation states — idle, running-right, running-left, waving, jumping, failed, waiting, running, review). Calls OpenAI GPT Image 2 edit ONCE via the local RunComfy CLI as runcomfy run openai/gpt-image-2/edit to produce a canonical Codex Pet pose, then assembles all 9 animation rows programmatically with ImageMagick micro-transforms — no Codex Pro, no $imagegen, no OPENAIAPIKEY required, only RUNCOMFYTOKEN. Triggers on "codex pet", "create codex pet", "make codex pet", "hatch codex pet", "/hatch image", "desktop pet codex", "codex pets", "spritesheet.webp", or any explicit ask to build a custom pet for OpenAI Codex.
