Q: How do I install nanoclaw-traffic-guardian?

Run npx skills add https://github.com/prompt-security/clawsec --skill nanoclaw-traffic-guardian 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/nanoclaw-traffic-guardian/ (personal) or .claude/skills/nanoclaw-traffic-guardian/ (project).

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/prompt-security/clawsec --skill nanoclaw-traffic-guardian

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 nanoclaw-traffic-guardian automatically when relevant.
03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

NanoClaw Traffic Guardian

This is a baseline specification skill. It intentionally does not ship a proxy or runtime implementation yet.

Vercel Skills Installation

Install with the Vercel Skills CLI for this harness:

npx skills add prompt-security/clawsec --skill nanoclaw-traffic-guardian -a openclaw -y

Release Artifact Verification

For standalone installs, verify the signed release manifest before trusting SKILL.md, skill.json, or the archive. The skill.json file is the package metadata/SBOM source, and the release pipeline signs checksums.json with the ClawSec release key.

Scope

Builders should use this skill as the NanoClaw landing zone for runtime traffic monitoring:

host-side HTTP proxy inspection
optional HTTPS inspection with host-held CA material
outbound exfiltration detection
inbound injection detection
redacted local threat logs
MCP tools for status, findings, and config checks
IPC handlers for container-safe host communication

Prefer this as an optional companion to clawsec-nanoclaw, not as a mandatory extension of the existing advisory/signature/integrity suite.

Safety Contract

Opt-in only.
Detect-and-log by default.
No automatic system CA installation.
No CA private key access from the container.
No blocking in the first implementation.
Redact secrets before logs or MCP responses.
Keep all state under NANOCLAW_TRAFFIC_GUARDIAN_HOME or the host-managed NanoClaw security data directory.

Builder Entry Points

Read SPEC.md before implementing. Use the placeholder folders as follows:

Path	Intended use
`lib/`	Detector rules, redaction, types, report formatting
`host-services/`	Host-side proxy lifecycle, log access, IPC handlers
`mcp-tools/`	Container-side MCP tools for status and findings
`test/`	Unit tests, host/container IPC tests, redaction tests

Required First Implementation Behavior

Validate config without starting the proxy.
Start monitor through a host-managed lifecycle path.
Keep CA key material on the host side.
Inspect HTTP request/response text up to a bounded byte limit.
Support optional HTTPS MITM only when the operator supplies per-runtime trust configuration.
Emit JSONL findings with redacted snippets.
Expose MCP tools that return status and redacted findings only.

Out of Scope for v0.0.1 Implementation

automatic system trust-store mutation
transparent network interception
default blocking
sending traffic to external services
exposing raw request/response bodies to the container

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).

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).

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.
