nanoclaw-whatsapp: Skill for Claude Code

.claude/skills/use-native-credential-proxy/SKILL.md

use-native-credential-proxy is a skill for Claude Code from nanocoai/nanoclaw-whatsapp. It costs 50 tokens per session (1,450 once invoked), scanned A, a copy of use-native-credential-proxy, MIT.

A built-in local credential proxy for NanoClaw, a system that runs agents in containers. It reads API keys or OAuth tokens from a .env file and supplies them to container requests through a local HTTP connection.

In plain words
What is it for?
It helps replace OneCLI, enable NanoClaw's native credential handling, check whether the proxy is already active, and apply the related code changes.
Why use it?
It removes the need for the separate OneCLI gateway or another external credential service. Credentials can stay in local configuration while containers receive them when making API requests.

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

use-native-credential-proxy 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 12d 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.

Use Native Credential Proxy

This skill replaces the OneCLI gateway with NanoClaw's built-in credential proxy. Containers get credentials injected via a local HTTP proxy that reads from .env — no external services needed.

Phase 1: Pre-flight

Check if already applied

Check if src/credential-proxy.ts is imported in src/index.ts:

grep "credential-proxy" src/index.ts

If it shows an import for startCredentialProxy, the native proxy is already active. Skip to Phase 3 (Setup).

Check if OneCLI is active

grep "@onecli-sh/sdk" package.json

If @onecli-sh/sdk appears, OneCLI is the active credential provider. Proceed with Phase 2 to replace it.

If neither check matches, you may be on an older version. Run /update-nanoclaw first, then retry.

Phase 2: Apply Code Changes

Ensure upstream remote

git remote -v

If upstream is missing, add it:

git remote add upstream https://github.com/qwibitai/nanoclaw.git

Merge the skill branch

git fetch upstream skill/native-credential-proxy
git merge upstream/skill/native-credential-proxy || {
  git checkout --theirs package-lock.json
  git add package-lock.json
  git merge --continue
}

This merges in:

  • src/credential-proxy.ts and src/credential-proxy.test.ts (the proxy implementation)
  • Restored credential proxy usage in src/index.ts, src/container-runner.ts, src/container-runtime.ts, src/config.ts
  • Removed @onecli-sh/sdk dependency
  • Restored CREDENTIAL_PROXY_PORT config (default 3001)
  • Restored platform-aware proxy bind address detection
  • Reverted setup skill to .env-based credential instructions

If the merge reports conflicts beyond package-lock.json, resolve them by reading the conflicted files and understanding the intent of both sides.

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.
