Auto Authenticator Local is a privacy-first skill for generating TOTP codes on the user's machine.

What this skill does

• Adds a TOTP seed to the operating system credential vault under a user-chosen alias.
• Generates the current 6-digit code for a single alias on explicit request.
• Deletes a stored alias when the user rotates or removes access.
• Helps the user integrate approved local login flows for accounts they own or are authorized to manage.

Hard safety rules

• Refuse any request framed as bypassing MFA, avoiding rate limits, defeating anti-abuse systems, or "hiding" OTP generation from security controls.
• Do not store TOTP seeds in plaintext files, shell history, screenshots, prompts, git, or chat transcripts.
• Do not bulk-export secrets or dump all aliases.
• Do not generate codes silently in the background. Require an explicit alias each time.
• If the account ownership or authorization is unclear, pause and ask for confirmation before helping.

Platform assumptions

• The bundled scripts are cross-platform through keyring, which maps to OS-native secure storage.
• macOS also has a built-in fallback through the security CLI.
• If the host machine does not have a working secure storage backend, help the user install one rather than falling back to plaintext.

Files to use

• scripts/totp_add.py: store or update a TOTP seed in secure storage
• scripts/totp_code.py: generate the current 6-digit code for one alias
• scripts/totp_delete.py: delete an alias from secure storage
• references/security.md: storage and publication guidance

Default workflow

1. Confirm the user owns the account or is authorized to manage it.
2. Ask for a short alias that does not leak unnecessary sensitive context.
3. Store the seed with:
   • python3 scripts/totp_add.py --alias <alias> --issuer <issuer> --account <account>
4. Generate a code only when explicitly requested:
   • python3 scripts/totp_code.py --alias <alias>
5. Remove the seed if the account is decommissioned or rotated:
   • python3 scripts/totp_delete.py --alias <alias>

Response style

• Keep generated output minimal.
• Prefer returning only the code and its expiry when that is what the user asked for.
• When discussing storage or rollout, emphasize privacy, explicit invocation, and device-local handling.
• If the user asks about publishing, position the skill as a local privacy and convenience tool for legitimate access.

Good deliverables

• A local setup guide
• A security checklist
• A migration plan from plaintext secrets to Keychain
• A small integration for approved local login steps

Avoid

• Marketing copy about bypassing protections
• Stealth or hidden code generation
• Unauthorized access flows
• Secret export or exfiltration helpers
