suna: Skill for Claude Code

.claude/skills/sdk/SKILL.md

sdk is a skill for Claude Code from kortix-ai/suna. It costs 149 tokens per session (9,252 once invoked), scanned A, original, no licence file.

A set of project-specific rules for editing the published @kortix/sdk npm package, including its tests and exported names. TDD means writing a failing test before the code that makes it pass.

In plain words
What is it for?
Use it when changing the SDK, its tests, or any exported function, class, value, or type.
Why use it?
It prevents changes from breaking the package’s public interface or skipping required tests. It also makes the project’s release checks explicit.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is kortix-ai/suna's own configuration. It tells Claude Code how to work on suna itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything suna configures →

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Memory Poisoning · line 227
    Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.
    Fix: Protect agent memory and state from modification by untrusted content. Use read-only memory for critical instructions and validate all state changes.
  • medium Agent Snooping · line 543
    Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
    Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sdk scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Expected in a hook, worth knowing in a rule or an instructions file.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
