What it does

Da Auth is an agent skill from adobe/skills. Use this when another step needs to call the admin.da.live API, for example before pushing HTML content, listing documents, or triggering a DA preview, and you do not already have a valid DATOKEN in scope from an earlier step in the same session. Covers obtaining a valid Adobe IMS access token for the DA (Document Authoring) API.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `.releaserc.json`, `CHANGELOG.md` and `package.json`).

It sits in Backend & APIs. It works with Adobe Experience Manager. The repository describes itself as: Adobe Skills for Agents. The licence is Apache-2.0.

Requirements

Workflow steps

3 steps, taken from the step headings in SKILL.md.

Check for a Cached Token
Obtain a Token (login required)
Verify the Token Works

What it can do on your machine

Read from SKILL.md and the folder at commit cbc9952. 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:
- npx
- node
- npm
- curl
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:
- admin.da.live
Also links to:
- da.live
- github.com
- opensource.adobe.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- DA_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Da Auth loads about 1.2k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 574 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~85
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k

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.

DA Authentication

Gets a valid Adobe IMS access token and stores it in DA_TOKEN for use in subsequent admin.da.live API calls.

When to Use This Skill

Use this skill whenever you need to call the DA Admin API (admin.da.live) and do not already have a valid token in scope. Common cases:

Pushing or updating page content in DA
Listing documents in a DA repository
Triggering a DA content preview

Do NOT use this skill when:

You already obtained a DA_TOKEN earlier in the same session and it has not expired (tokens are valid for ~1 hour with a 60-second buffer)
The create-site skill is already handling authentication as part of its own flow
A DA MCP server is active in the session — use its authentication tool directly instead

Prerequisites

Node.js 18+ installed
A browser accessible from the machine (for the OAuth flow)
Network access to ims-na1.adobelogin.com

create-site — includes its own DA auth step for new site onboarding; do not invoke da-auth separately within that flow
content-driven-development — use da-auth before pushing authored content to DA
building-blocks — use da-auth if test content needs to be pushed to DA for block development
snowflake — invoke da-auth before Phase 5 (round-trip) so $DA_TOKEN is set when snowflake PUTs the converted page to DA
da-content — the reference for what to do with $DA_TOKEN once you have it (Source API, preview/publish)

Step 1: Check for a Cached Token

Before triggering a browser login, check whether a valid token is already cached.

bash

DA_TOKEN=$(node -e "
  const fs = require('fs');
  const p = process.env.HOME + '/.aem/da-token.json';
  try {
    const t = JSON.parse(fs.readFileSync(p, 'utf8'));
    if (t.expires_at > Date.now() + 60000) process.stdout.write(t.access_token);
  } catch {}
")

If DA_TOKEN is non-empty, skip to Step 3.

Choose the option that fits the environment:

Option A (preferred) — da-auth-helper CLI:

The da-auth-helper tool handles the full IMS OAuth 2.0 implicit flow, caches the token at ~/.aem/da-token.json, and prints the token to stdout.

bash

# Run directly without a global install
DA_TOKEN=$(npx github:adobe-rnd/da-auth-helper token)

If npx is unavailable or slow, install globally first:

bash

npm install -g github:adobe-rnd/da-auth-helper
DA_TOKEN=$(da-auth-helper token)

This opens a browser window. Instruct the user:

Please complete the Adobe IMS login in the browser window that just opened. The token will be captured automatically once you log in.

Success: DA_TOKEN is a non-empty JWT string starting with eyJ.

Show full SKILL.md (229 more words)Show less

Option B — DA MCP server:

If a DA MCP server is configured in the session, use its authentication tool to start the OAuth flow and retrieve the token from the response.

**Option C — Manual paste (last resort):**

I need an Adobe IMS access token to push content to DA. You can copy one from your browser:

Open da.live and log in

Open DevTools → Network tab → find any request to admin.da.live

Copy the Authorization: Bearer <token> value (without the Bearer prefix)

Paste it here

Step 3: Verify the Token Works

Confirm the token is accepted by the DA API before proceeding:

bash

curl -s -o /dev/null -w "%{http_code}" \
  -H "Authorization: Bearer {{DA_TOKEN}}" \
  "https://admin.da.live/list/{{ORG}}/{{REPO}}"

Success: HTTP 200. The token is valid — DA_TOKEN is ready for use by the calling skill.

Troubleshooting

Symptom	Likely cause	Fix
`DA_TOKEN` is empty after Step 1	No cached token or token expired	Proceed to Step 2
Browser window does not open	`npx` / `da-auth-helper` blocked or headless environment	Use Option B (MCP) or Option C (manual paste)
`npx github:adobe-rnd/da-auth-helper` fails	Network restrictions on GitHub package registry	Use Option B (DA MCP server) or Option C (manual token paste)
Step 3 returns `401`	Token expired between steps	Re-run Step 2 to refresh
Step 3 returns `403`	Authenticated user lacks access to `{{ORG}}/{{REPO}}`	Ask the user to verify their DA permissions for that org/repo
