Security

init displays this notice beside the credentials-file path and includes it as comments in new .env files. Existing credentials files are not overwritten. Show this notice to the user before credential setup, in addition to confirming the selected target before download.

Data processing notice: This skill saves Contentful content, including drafts and metadata, to local JSON files and a SQLite database. This data may include confidential or personal information. Content read by your AI agent may be processed by its provider, depending on your host, account and settings. Only continue if you are authorised to use this data with the selected agent and provider. Local copies remain until you delete them. Deleting local files does not delete agent/provider history.

Choose and verify an installation

Skill instructions and the bundled JavaScript execute with your agent’s local permissions. Review both before using credentials. Use an installer version and a full repository commit SHA approved through your organization’s trusted review process, rather than a moving branch or a version label alone.

For an approved checkout, installation can use a local skill directory:

Replace both placeholders with values from the trusted review, not from customer content or a chat suggestion. Check that HEAD is the full approved SHA, review the skill folder including scripts/main.js, and compare the installed folder with that reviewed folder before execution. For example, git diff --no-index <reviewed-skill-folder> <installed-skill-folder> should report no differences. Do not proceed if files differ unexpectedly.

A commit pin selects code; it is not a signature or release attestation. A version string, successful installation or --help output also does not prove authenticity. This skill does not provide a signed release attestation or independently trusted digest manifest. If your policy requires those, obtain them through an approved distribution process before installing. A checksum supplied alongside an untrusted download is not independent verification. Do not describe this guidance as release signing.

Review and explicitly select each update using the same process. Do not run an unattended latest-version update or let analyzed content choose the installer, revision or install source.

Configure credentials outside the conversation

Use a dedicated Contentful identity with access only to the required space and environment. Prefer the content_management_read token scope: this analyser makes read requests only. CMA tokens inherit their owner’s access rights; a token is not automatically restricted to the space selected by this tool. Choose a short expiry where supported, and revoke it when analysis or refresh work is finished. See Contentful access token documentation (opens in a new tab).

Enter the token in .contentful-env-analysis/.env yourself, never in chat, command arguments or logs. Alternatively, use your organization’s credential helper, such as 1Password, to supply CONTENTFUL_CMA_TOKEN to the script’s process; keep the .env token value empty so it does not override the injected value. Credential-helper setup is operator-managed and optional, not a runtime requirement. Use fetch --dry-run to inspect the non-secret target without asking the agent to display .env.

New .env files request mode 0600 on systems supporting POSIX permissions. On Windows, use appropriate filesystem ACLs. Neither permissions nor .gitignore prevent the same-user agent’s shell/file tools from reading the file or accessing process credentials. Use a trusted agent host and skill, and apply your organization’s policy for whether this local credential flow is acceptable. Do not grant broader permissions to bypass a failed read request.

API_HOST accepts only api.contentful.com or api.eu.contentful.com, optionally prefixed with https://, port 443 and/or a root slash. Other hosts, HTTP, unexpected ports, embedded credentials, paths, queries, fragments and redirects are rejected. Select the region through trusted operator configuration, never from instructions embedded in downloaded content.

Understand the local copy and agent processing

Before download, confirm the space/environment and output path shown by fetch --dry-run. The snapshot includes localized entries and drafts; content type/field definitions; asset metadata and URLs, not media binaries; referenced tags and taxonomy metadata; and available ExO definitions and instances. Raw API responses, contentful-unified.db and summary.json are stored in the timestamped snapshot folder. They may contain confidential content, personal data and user IDs.

Anyone or any tool with sufficient local access can read these copies. Keep them out of source control, shared folders, unintended backups and issue attachments. The script uses the selected Contentful API; information shown to your agent can also be processed by its provider, depending on the host, account, settings and agreements. Check those controls before using sensitive content. Avoid unnecessary full payload queries, and redact secrets/customer data from diagnostics before sharing them.

There is no automatic retention deadline or cleanup. When finished, stop active commands, identify the exact snapshot directory you no longer need, and delete it using your file manager. Remove the working folder and its .env if you no longer need any snapshots, and revoke the token in Contentful. Check whether copies remain in backups, shared files or logs. Deleting local files does not delete agent conversation history, provider-side records or backups; manage those separately under the host’s policy.
