What it does

Keypo Signer is an agent skill from keypo-us/keypo-cli. Use when managing Secure Enclave signing keys or encrypted secrets. Use for creating/listing/deleting P-256 keys, signing digests, running commands with secrets injected via vault exec, storing/retrieving encrypted secrets. Also use when an agent needs API keys, private keys, or credentials injected into a subprocess without exposing them. Use vault sessions for unattended agent workflows that need repeated access to protected secrets.

Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs. The repository describes itself as: Local-first, hardware-bound key management and encrypted secrets for AI agents.

When your agent uses it

Managing Secure Enclave signing keys
Encrypted secrets
Creating/listing/deleting P-256 keys
Signing digests

Example prompts

“/keypo-signer”

Requirements

Python 3
A credential in PIMLICO_API_KEY
A credential in DEPLOYER_PRIVATE_KEY

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

Human creates a session (one-time, interactive)
Agent uses the session (repeated, unattended)
Session expires automatically after TTL or usage limit.

What it can do on your machine

Read from SKILL.md and the folder at commit 7331b6f. 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
Shell commands in SKILL.md call:
- vault
- sh
- brew
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- API_KEY
- PIMLICO_API_KEY
- DEPLOYER_PRIVATE_KEY
- DB_PASSWORD
- EXTRA_SECRET
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Keypo Signer loads about 3.6k tokens when it runs. Until then it costs about 113 tokens; SKILL.md has 1,352 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~113
When it runs · the whole SKILL.md, loaded when a task matches: ~3.6k

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.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

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.

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,352 words (~3,608 tokens).

“A CLI for hardware-bound P-256 key management and encrypted secret storage using the Apple Secure Enclave. Keys never leave the hardware. Secrets are encrypted at rest and decrypted only into child process environments.”
