At a glance

Lets the agent list and read the secrets a user has configured, such as API keys and tokens, through two tai tools instead of hardcoding credentials into code or commands.

  • Works in 3 steps: secret_list — discover what secrets are… → secret_read — retrieve a specific secret… → Use the value in API calls, git auth, etc.
  • A script needs an API key or token the user has already configured
  • SKILL.md covers secret_list, secret_read, Typical Workflow and Guidelines
  • Needs GITHUB_TOKEN and AWS_SECRET_KEY

What it does

This skill documents two tools called through bash with the tai command. secret_list returns the names and descriptions of the secrets configured for the current assistant but never their values. secret_read takes a name, such as GITHUB_TOKEN or AWS_SECRET_KEY, and returns the decrypted value for use in scripts. All output is JSON.

The intended order is to list first, confirm the needed secret exists, and only then read it and use it in API calls or git authentication. Credentials are never hardcoded, values are decrypted only at read time, and the agent is told not to log, print or expose a returned value anywhere users can see it. If a secret is missing, the agent asks the user to add it in their settings.

When your agent uses it

  • A script needs an API key or token the user has already configured
  • Checking which secrets are available before calling a service
  • Authenticating git or an API call without writing credentials into files

Example prompts

  • “Which secrets do I have configured? List the names only.”
  • “Read GITHUB_TOKEN and use it to clone the private repo.”
  • “Call the weather API with the key I stored as WEATHER_API_KEY, without printing it.”

Requirements

  • The tai command-line tool
  • Secrets configured in the assistant's settings

Workflow steps

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

  1. secret_list — discover what secrets are available
  2. secret_read — retrieve a specific secret by name
  3. Use the value in API calls, git auth, etc.

What it can do on your machine

Read from SKILL.md and the folder at commit eea1e7e. 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 (its code samples are bash).

    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:

    • GITHUB_TOKEN
    • AWS_SECRET_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Yao Secret Access loads about 415 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 160 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~415

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 160 words (~415 tokens).

“Two tools for accessing user-configured secrets, called via bash.”
