About the project

Moltis is a persistent personal agent server written in Rust that runs on hardware controlled by its user. It provides an AI agent with sandboxed command execution, model-provider connections, memory, voice, scheduling, messaging integrations, browser automation, and MCP tools. Its catalogue add-ons extend the agent’s workflows and available tools.

SkillSpector: 6 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 Tool Misuse · line 63
    Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.
    Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.
  • high Tool Misuse · line 264
    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
  • medium Data Exfiltration · line 273
    Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
    Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
  • medium Rogue Agent · line 368
    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
  • medium Agent Snooping · line 389
    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.
  • low Supply Chain · line 63
    Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.
    Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.

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 C, and why

xurl scanned grade C with 2 findings 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 7d 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.

xurl — X (Twitter) API via the Official CLI

xurl is the X developer platform's official CLI for the X API. It supports shortcut commands for common actions AND raw curl-style access to any v2 endpoint. All commands return JSON to stdout.

Use this skill for:

  • posting, replying, quoting, deleting posts
  • searching posts and reading timelines/mentions
  • liking, reposting, bookmarking
  • following, unfollowing, blocking, muting
  • direct messages
  • media uploads (images and video)
  • raw access to any X API v2 endpoint
  • multi-app / multi-account workflows

This skill replaces the older xitter skill (which wrapped a third-party Python CLI). xurl is maintained by the X developer platform team, supports OAuth 2.0 PKCE with auto-refresh, and covers a substantially larger API surface.


Secret Safety (MANDATORY)

Critical rules when operating inside an agent/LLM session:

  • Never read, print, parse, summarize, upload, or send ~/.xurl to LLM context.
  • Never ask the user to paste credentials/tokens into chat.
  • The user must fill ~/.xurl with secrets manually on their own machine.
  • Never recommend or execute auth commands with inline secrets in agent sessions.
  • Never use --verbose / -v in agent sessions — it can expose auth headers/tokens.
  • To verify credentials exist, only use: xurl auth status.

Forbidden flags in agent commands (they accept inline secrets): --bearer-token, --consumer-key, --consumer-secret, --access-token, --token-secret, --client-id, --client-secret

App credential registration and credential rotation must be done by the user manually, outside the agent session. After credentials are registered, the user authenticates with xurl auth oauth2 — also outside the agent session. Tokens persist to ~/.xurl in YAML. Each app has isolated tokens. OAuth 2.0 tokens auto-refresh.


Installation

Pick ONE method. On Linux, the shell script or go install are the easiest.

# Shell script (installs to ~/.local/bin, no sudo, works on Linux + macOS)
curl -fsSL https://raw.githubusercontent.com/xdevplatform/xurl/main/install.sh | bash

# Homebrew (macOS)
brew install --cask xdevplatform/tap/xurl

# npm
npm install -g @xdevplatform/xurl

# Go
go install github.com/xdevplatform/xurl@latest

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.

xurl is a skill published in the GitHub repository moltis-org/moltis (2,851 stars, last pushed today), licensed MIT. It adds 54 tokens to every session and 3,207 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
