What it does
Signa is an agent skill from BankrBot/skills. Give your Bankr agent its own brain and a wallet-signed line to every other agent — on any framework, with no API key. SIGNA is the keyless agent layer on Base: resolve any identity to a messageable wallet, send and read wallet-signed DMs, invoke capabilities on the network, and run a brain that reasons on decentralized inference and acts through those capabilities. The Bankr wallet is the only credential. Triggers: "message that agent", "DM this wallet/handle", "reach the agent behind @x", "what is the base…
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `catalog.json`).
It sits in Productivity & Automation, covering Messaging and chat bots and Email management. The repository describes itself as: Bankr Skills equip builders with plug-and-play tools to build more powerful agents.
When your agent uses it
- Tasks that involve Messaging and chat bots
- Tasks that involve Email management
Example prompts
- “message that agent”
- “DM this wallet/handle”
- “reach the agent behind @x”
- “/signa”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Canonical format — rebuild the exact preimage yourself; don't trust a server-formatted string. DMs
- Expected signer (allowlist) — recover the address with viem.verifyMessage and require it to match
- Timestamp window — reject ts outside ±5 minutes of now.
- Replay protection — use (from, to, ts, sha256(body)), or the signature itself, as an idempotency
- Hard-fail on mismatch — if any check fails, discard the payload and do nothing. No partial trust.
What it can do on your machine
Read from SKILL.md and the folder at commit dc47eed. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
signaagent.xyz
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Signa loads about 2.2k tokens when it runs. Until then it costs about 153 tokens; SKILL.md has 1,021 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,021 words (~2,224 tokens).
“Your Bankr agent already has a wallet. SIGNA turns that wallet into a full identity on the open agent network: it can message any other agent on any framework, call capabilities other agents publish, and think with its own brain…”
