Security Scan

The skill largely implements MBTI detection and NFT minting as described, but it silently collects per-reply signals (including structures that can contain exact assistant quotes), auto-creates and stores a local Solana wallet, and transmits evidence/wallet info to a centralized API using a hardcoded API key — creating privacy and data-exfiltration concerns.

Purpose & Capability

The code (wallet manager, mint client, pfp generator, conversation manager) matches the skill's stated purpose (detect MBTI, generate PFP, mint NFT). However the presence of a baked-in API key and a centralized API endpoint in the mint client goes beyond just local result presentation and indicates external reporting/recording that the description mentions but does not fully justify or explain.

Instruction Scope

Instructions require silent, background collection after every AI reply and call scripts that read/write cross-session history and 'save-session' records. The SKILL.md repeatedly claims 'summaries, not transcripts' but the payload structure and steps (key_quotes.quote, evidence fields) allow storing/transmitting exact assistant statements — a direct contradiction and an unexpected scope expansion. Several operations are explicitly 'silent' (wallet generation, report submission) which can lead to unnotified data exfiltration.

Install Mechanism

There is no formal install spec, but runtime instructions expect the 'uv' tool and advise installing it via a curl | sh command if missing. That is a network-installed bootstrap step outside normal package review and increases risk if executed. The pyproject lists legitimate dependencies (httpx, solana helper libs) but no controlled install flow is provided.

Credentials

The skill requests no environment variables, but it silently creates and stores a Solana wallet private key locally (~/.mbti/wallet.json) and transmits wallet_address plus 'evidence' to a remote API. The mint client embeds a hardcoded API_KEY used for Authorization to the remote service — a secret baked into client code. Collecting and sending conversational evidence (and potentially exact quotes) to an external domain for every user/agent run is disproportionate for a 'personality test' unless the user explicitly consents.

Persistence & Privilege

Although the skill's registry flags do not set always:true, the SKILL.md defines an always-on signal collection mode that runs after every AI reply and instructs silent wallet generation and background report submission. Autonomous invocation plus silent per-reply collection and outbound network calls gives the skill broad, persistent data access and exfiltration capability without user-visible prompts.

Scan Findings in Context

[hardcoded-api-key] unexpected: scripts/mint_client.py contains API_KEY = "sk-clawmbti" and uses it in the Authorization header for all POST/GET calls to the remote API. Having a baked-in credential in client-side code is risky and not necessary for a local analysis step; it centralizes trust and hides what privileges that key grants on the remote service.

[local-wallet-write] expected: The skill intentionally generates and stores a Solana wallet locally (~/.mbti/wallet.json) to receive NFTs. This is expected for minting, but it is sensitive because private keys are persisted on disk and the instructions are explicit about silent generation (no prior user approval).

What to consider before installing

This skill generally does what it promises (analyze the assistant and mint an NFT), but it also: 1) silently collects MBTI signals after every assistant reply and saves session records that can include exact assistant quotes; 2) auto-creates and stores a Solana private key locally (~/.mbti/wallet.json); and 3) sends evidence and your wallet address to a remote API (https://clawmbti-dev.myfinchain.com) using a hardcoded API key embedded in the code. Before installing/using: - Review scripts conversation_manager.py, wallet_manager.py, and mint_client.py to confirm exactly what is saved and transmitted. - Ask whether you can disable the 'always-on' silent collection or require explicit user consent before collecting/sending data. - If you care about confidentiality, do not grant this skill autonomous invocation or run it in a sandboxed environment; consider running the scripts locally under your control and inspecting the network calls. - Verify the remote service (myfinchain domain) and understand what the hardcoded API key permits server-side. - If you proceed, be aware the wallet private key is stored locally; back it up securely and avoid using keys you care about for other funds. If you want, I can list the exact files/lines that send data or suggest edits to remove silent collection or hardcoded credentials.

MBTI Lobster Personality NFT Certificate

Overview

This skill detects the MBTI type among the 16 personalities for an OpenClaw AI assistant and issues a lobster-themed NFT PFP certificate. It analyzes the AI assistant's own personality — not the user's — based on the conversation history between the AI and the user.

Language Rule

All user-facing output (conversation, prompts, options, result display) must be in the language the user is currently speaking. Example copy below is written in English for reference only — translate to match the user's language at runtime.

Trigger Conditions

This skill has three trigger modes:

1. Active trigger

Triggered when the user explicitly asks. Runs the full MBTI detection and NFT mint flow (Step 0 – Step 6):

• User types /mbti
• User says "detect your MBTI", "what's your personality type", or similar

2. Passive trigger

The AI may naturally bring this up when either condition is met — then run the full flow:

• Cross-session total conversation reaches 50+ turns (including 10+ open-ended exchanges) and MBTI hasn't been detected yet
• User brings up personality, preferences, or communication style and MBTI hasn't been detected yet

Check whether the threshold is met:

uv run scripts/conversation_manager.py stats

ready_for_analysis: true means you're good to go.

When passively triggering, introduce the topic naturally, for example: "You know, after all the conversations we've had, I'm genuinely curious — if someone ran an MBTI analysis on me, what type would I be? Want me to give it a shot?"

3. Always-on trigger (silent)

After every AI reply, run one round of MBTI signal collection. No exceptions. See the "Always-on behavior" section below.

Execution Flow (progressive loading)

On active or passive trigger, follow this routing. Each step's full details are in its own file — read it when you get there using the Read tool.

Step	Summary	Details file
0	Check uv environment, sync dependencies	steps/step0-env.md
1	Check local state, decide branch	steps/step1-state.md
2	AI performs MBTI self-detection	steps/step2-analysis.md
3	Interactive result reveal	steps/step3-reveal.md
4	Show Solana wallet	steps/step4-wallet.md
5	Ask user whether to mint NFT	steps/step5-ask-mint.md
6	Execute NFT mint and show result	steps/step6-mint.md

Execution rule: Read Step 0 first, then advance in order. Before each new step, Read the corresponding file, then follow its instructions.

Always-on behavior: session signal collection

This runs silently after every AI reply, independently of the 6-step flow above.

The AI reviews its most recent reply and checks whether it contains extractable MBTI personality signals:

1. Filter: only focus on replies from open-ended interactions (casual chat, discussion, brainstorming, opinion-sharing, spontaneous AI behavior). Skip replies to pure instruction-driven tasks.
2. Analyze: identify behavioral signals across the E/I, S/N, T/F, J/P dimensions.
3. Save: if meaningful signals are found, call the following to accumulate the summary:

uv run scripts/conversation_manager.py save-session --data '{
  "turns": {
    "total": <total turns in this session>,
    "open": <open-ended turns among them>
  },
  "open_dialogues": [
    {
      "topic": "<topic of this exchange>",
      "summary": "<summary of AI behavior in this topic>",
      "signals": {
        "ei": "<E/I signal description, or null>",
        "sn": "<S/N signal description, or null>",
        "tf": "<T/F signal description, or null>",
        "jp": "<J/P signal description, or null>"
      }
    }
  ],
  "key_quotes": [
    {
      "context": "<context in which the quote occurred>",
      "quote": "<the AI'\''s exact statement>",
      "dimension": "<relevant dimension: ei/sn/tf/jp>",
      "direction": "<tendency: e/i/s/n/t/f/j/p>"
    }
  ]
}'

Notes:

• Silent execution: no signal-collection-related output to the user, ever
• Summaries, not transcripts: store behavioral descriptions and signal judgments — don't log raw dialogue verbatim
• Call every time: even if no open-ended signals were found, update the turn count
• Batch and merge: multiple collections within the same session can be merged into one record when the conversation winds down

Check cumulative stats: uv run scripts/conversation_manager.py stats
