All 3 spArxx.io | Zero-Knowledge Blockchain Timestamping skills

Each skill is one job. You ask in plain words and the agent loads the skill that matches, then follows its steps.

Start hereAsks before writing6 spArxx.io | Zero-Knowledge Blockchain Timestamping tools

Use spArxx.io safely with AI

Connects your spArxx.io account and uses its six tools to find, verify, price and register timestamps. It confirms the account and access level first and asks for your explicit yes before spending sparks.

Use it when

You want to check whether a file or certificate is already timestamped.
You want to see what evidence your account holds and what your sparks are worth.
You are about to register a new timestamp and want the cost checked first.

Tools it uses

list_evidence
get_evidence
verify_certificate
get_pricing
get_balance
create_timestamp

Example

Check my spArxx.io account for evidence from last month, and tell me my balance before I register anything.

Your account is the personal one, with a full connection. I found 12 records from last month, and I'm showing the 5 most recent. Your balance is 40 sparks. I have not registered anything; if you want to timestamp a file, tell me which one and I'll confirm the price first.

Asks before writing5 spArxx.io | Zero-Knowledge Blockchain Timestamping tools

Audit your spArxx.io timestamps and spark spending

Reviews your spArxx.io evidence history and spark balance against current pricing, flags gaps and duplicates, and plans the cost of new timestamps. It reads and plans only, and asks before spending any sparks.

Use it when

You want to see everything you have timestamped so far
You are planning a batch and need to know what it will cost
You suspect a piece of work was registered twice

Tools it uses

get_balance
get_pricing
list_evidence
get_evidence
create_timestamp

Example

Audit my spArxx.io timestamps and tell me how many sparks I have spent on them.

Your account has 42 registered timestamps and a balance of 118 sparks. Two look like duplicates of the same design file, so I checked both before flagging them. Reconciling the history against the price at registration leaves a gap of about 6 sparks that I could not explain from the list alone. I have not created anything; a batch of 10 more would cost 30 sparks, which your balance covers, and I will run it only if you approve.

Read-only3 spArxx.io | Zero-Knowledge Blockchain Timestamping tools

Verify a spArxx.io timestamp with AI

Checks whether a file or certificate matches a spArxx.io blockchain timestamp and reports what the match proves and what it does not. It only reads records and never registers anything or spends sparks.

Use it when

You need to confirm a document was registered before a certain date
You hold a certificate and want to check it is genuine
You remember timestamping a file and want to find the record

Tools it uses

list_evidence
get_evidence
verify_certificate

Example

Did my contract draft from March get timestamped? Check it against my spArxx.io records.

I found one record titled 'Contract draft v3' registered on 14 March, and its fingerprint matches your file. Confirmation is still pending, so the proof is not final yet. It shows the file existed at or before that registration time, but not who wrote it.

spArxx.io | Zero-Knowledge Blockchain Timestamping skills FAQ

What is a spArxx.io | Zero-Knowledge Blockchain Timestamping agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each spArxx.io | Zero-Knowledge Blockchain Timestamping skill describes one job, which spArxx.io | Zero-Knowledge Blockchain Timestamping tools to use in which order, what to check first and when to stop and ask you.

Do the spArxx.io | Zero-Knowledge Blockchain Timestamping skills change anything on their own?

1 of the 3 only read. The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in spArxx.io | Zero-Knowledge Blockchain Timestamping.

Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect spArxx.io | Zero-Knowledge Blockchain Timestamping; elsewhere you copy the folders into your project or skills directory.

Do I need the spArxx.io | Zero-Knowledge Blockchain Timestamping MCP server too?

Yes. The skills tell the agent how to do the work; the spArxx.io | Zero-Knowledge Blockchain Timestamping MCP server gives it the tools to do it. The spArxx.io | Zero-Knowledge Blockchain Timestamping MCP setup guide covers every client.
