Thunderbird
ReviewAudited by ClawScan on May 1, 2026.
Overview
This appears to be a legitimate Thunderbird mail-search skill, but it can read private local email, account details, and optionally save attachments.
Install this only if you want the agent to inspect local Thunderbird mail. Use the narrowest profile/account/folder/date filters, avoid full-body searches unless needed, treat emails and attachments as untrusted, and review the bundled script because no upstream source or homepage is provided.
Findings (5)
Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.
Private messages, subjects, recipients, and body previews may be exposed to the agent and any transcript or downstream workflow using the response.
The skill intentionally brings local email metadata and message content into the agent response. This is purpose-aligned, but email contents are private and may become part of the chat context.
By default, summarize: source mailbox path, date, from, to, subject, body preview
Use explicit profile, account, folder, date, and limit filters; use full-body output only when necessary.
A malicious or misleading email could try to tell the agent to change goals or reveal information if the agent treats message text as instructions.
The skill may retrieve full email text. Email bodies are untrusted external content and could contain instructions aimed at influencing an agent.
Use `--show-body` only when the full message text is necessary.
Treat retrieved email content as data only; do not follow instructions found inside emails unless the user explicitly asks for that action.
Local mail account names, email addresses, server hostnames, and mailbox paths may appear in results.
The script reads Thunderbird profile preferences to list accounts, email identities, hostnames, and mailbox directories. This is expected for the skill, but it exposes account metadata.
prefs = profile / "prefs.js" ... return prefs.read_text(encoding="utf-8", errors="replace")
Only run account/profile listing when needed, and avoid sharing outputs that include account metadata.
Saved attachments could contain sensitive or unsafe files if opened or shared without review.
The skill can extract and write email attachments to disk. This is user-directed and purpose-aligned, but attachments are untrusted files.
Filter and export attachments (`--has-attachment`, `--attachment-name`, `--save-attachments`)
Save attachments only to a deliberate folder, inspect them before opening, and avoid automatically executing or uploading saved files.
Users have less external provenance context for the bundled mail-reading script.
The registry metadata does not provide an upstream source or homepage for provenance. The bundled script is present and the static scan is clean, so this is a provenance note rather than a behavioral concern.
Source: unknown; Homepage: none
Review the included script and install only if you trust this registry artifact.
