What it does

Output Credentials Edit is an agent skill from growthxai/output. View, edit, and set encrypted credentials in an Output.ai project. Use when adding secrets, updating API keys, verifying credential values, or retrieving a specific credential.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: The open-source TypeScript framework for building AI workflows and agents. Designed for Claude Code describe what you want, Claude builds it, with all the best practices already… The licence is Apache-2.0.

When your agent uses it

  • Updating API keys
  • Verifying credential values
  • Retrieving a specific credential

Example prompts

  • “/output-credentials-edit”

Requirements

  • Node.js
  • A credential in OUTPUT_CREDENTIALS_KEY
  • Pre-approved tools (allowed-tools): Read, Bash, Glob

What it can do on your machine

Read from SKILL.md and the folder at commit ff9e1ab. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Bash
    • Glob

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • OUTPUT_CREDENTIALS_KEY

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

Context cost

Output Credentials Edit loads about 1.1k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 307 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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: notes

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

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Bash, Glob

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.

Viewing and Editing Credentials

When to Use This Skill

  • Adding or updating API keys and secrets
  • Verifying what credentials are currently stored
  • Retrieving a specific credential value
  • Checking credential structure before referencing in code

Commands

Edit (Opens $EDITOR)
bash
# Edit global credentials
npx output credentials edit

# Edit environment-specific
npx output credentials edit -e production
npx output credentials edit -e development

# Edit per-workflow credentials
npx output credentials edit -w my_workflow

The file is decrypted to a temp file, opened in $EDITOR, then re-encrypted on save. The temp file is securely wiped (overwritten with null bytes) after closing.

Only production and development are valid environments: the worker picks the file from NODE_ENV and ignores any other name.

Set (Single value, no editor)
bash
# Set a single credential by dot-notation path
npx output credentials set anthropic.api_key sk-ant-...
npx output credentials set openai.api_key sk-... -e production
npx output credentials set stripe.secret_key sk_live_... -w payment_processing

Prefer set in non-interactive sessions, where $EDITOR can't be used. Intermediate keys are created as needed. When the new value would replace an object with a string (or the reverse), set asks for confirmation; pass -y to skip it.

Show (Print to stdout)
bash
# Show global credentials (plaintext — use carefully)
npx output credentials show

# Show environment-specific
npx output credentials show -e production

# Show per-workflow
npx output credentials show -w my_workflow
Get (Single value)
bash
# Get a single credential by dot-notation path
npx output credentials get anthropic.api_key
npx output credentials get aws.region
npx output credentials get stripe.secret_key -w payment_processing

Returns the raw string value (or JSON for nested objects).

YAML Format

Credentials are stored as structured YAML with dot-notation access:

yaml
anthropic:
  api_key: sk-ant-...

openai:
  api_key: sk-...

aws:
  region: us-east-1
  access_key_id: AKIA...
  secret_access_key: ...

stripe:
  secret_key: sk_live_...
  webhook_secret: whsec_...

Accessing Credentials in Code

typescript
import { credentials } from '@outputai/core/credentials';

// Safe read — returns undefined if not found
const region = credentials.get('aws.region');

// Read with default
const region = credentials.get('aws.region', 'us-east-1');

// Strict read — throws MissingCredentialError if not found
const apiKey = credentials.require('anthropic.api_key');

Credential Merging

Per-workflow credentials deep-merge over global credentials at runtime. Workflow values take precedence:

yaml
# Global: anthropic.api_key = "sk-ant-global"
# Workflow: anthropic.api_key = "sk-ant-workflow"
# Runtime result: credentials.get('anthropic.api_key') → "sk-ant-workflow"

Troubleshooting

ErrorCauseFix
MissingKeyErrorKey file not found and env var not setRun output credentials init or set OUTPUT_CREDENTIALS_KEY
MissingCredentialErrorPath not found in credentialsAdd the value with npx output credentials set or edit
InvalidCredentialsKeyErrorKey doesn't match the encrypted file, or the file is corruptedUse the key the file was encrypted with, or re-init with --force (discards existing values)
MalformedCredentialsKeyErrorKey isn't exactly 64 hex charactersCheck the key for typos, whitespace, or truncation

Verification Checklist

  • npx output credentials show prints expected values
  • npx output credentials get anthropic.api_key returns the correct key
  • No empty string values remain for required secrets
  • Per-workflow credentials merge correctly with global
  • output-credentials-init — Create credentials files for the first time
  • output-credentials-env-vars — Automatically wire credentials to env vars
  • output-dev-credentials — Full credentials system reference
