io-connectorsGuides development and usage of I/O connectors in Apache Beam.
Io Connectors is an agent skill from Kilo-Org/kilo-marketplace. Guides development and usage of I/O connectors in Apache Beam. Use when working with I/O connectors, creating new connectors, or debugging data source/sink issues.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.
It sits in Databases, covering Event-driven systems, Integration testing and Data warehousing. It works with Google Cloud, Python, Apache Kafka and Google BigQuery. The repository describes itself as: Kilo Marketplace - A curated collection of Skills, MCP Servers, and Modes for enhancing AI agent capabilities across the Kilo ecosystem—including Kilo Code (VS Code extension)… The licence is Apache-2.0.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit ff51758. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are java and bash).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Io Connectors loads about 1.3k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 244 words of instructions outside code blocks.
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.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
The full file from Kilo-Org/kilo-marketplace at commit ff51758, republished under its Apache-2.0 licence (© Kilo-Org). 244 words, ~1,326 tokens.
.claude/skills/io-connectors/SKILL.md (or your agent's skills folder). This skill also uses 1 other file; get the full folder from GitHub.I/O connectors enable reading from and writing to external data sources. Beam provides 51+ Java I/O connectors and several Python connectors.

Guides development and usage of I/O connectors in Apache Beam. Io Connectors is an agent skill from Kilo-Org/kilo-marketplace. Guides development and usage of I/O connectors in Apache Beam.
Io Connectors fits situations like: working with I/O connectors; creating new connectors; debugging data source/sink issues.
Run `npx skills add Kilo-Org/kilo-marketplace --skill io-connectors -a claude-code`. Or copy the skill folder (skills/io-connectors in Kilo-Org/kilo-marketplace) into .claude/skills/io-connectors in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Kilo-Org/kilo-marketplace --skill io-connectors -a codex`. Or copy the skill folder (skills/io-connectors in Kilo-Org/kilo-marketplace) into .agents/skills/io-connectors in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Kilo-Org/kilo-marketplace --skill io-connectors -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/io-connectors, .gemini/skills/io-connectors, .github/skills/io-connectors and .opencode/skills/io-connectors in your project.
SKILL.md names no scripts, command-line tools or credentials: Io Connectors is instructions for the agent only. Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Io Connectors is published under the Apache-2.0 licence (from the LICENSE file in the skill folder). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.3k tokens (SKILL.md is roughly 5.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Io Connectors: BigQuery Slot and Cost Optimizer (google/skills, 21k stars), Bigquery Bigframes (google/skills, 21k stars), Cloud Monitoring Metric Selection (google/skills, 21k stars) and 323 Frameworks Spring Boot Testing Acceptance Tests (jabrena/plinth, 447 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Kilo-Org (a GitHub organization) maintains it in Kilo-Org/kilo-marketplace, which has 190 GitHub stars. The repository holds 86 skills in this directory. The repository was last updated on September 28, 2026.
