SaferSkills independently audited teams-message-formatting (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
Format supplied text for the Teams surface that receives it. The user's explicit instructions take precedence over this skill's guidelines.
Use the content, destination field, and existing payload or SDK as input. Infer the text system from that context; ask for the destination when the missing choice changes syntax or mention metadata.
| Surface | Text format | Mention metadata |
|---|---|---|
Bot activity text | Bot Markdown or textFormat: "xml" subset | Activity entities |
Adaptive Card TextBlock / facts | Limited Markdown, no HTML | Root msteams.entities |
Graph chatMessage.body | text or Teams-restricted html | Body <at id="N"> plus matching mentions entry |
Hero/thumbnail card text | XML/HTML subset | Surface-specific; titles/subtitles are unformatted |
Slack mrkdwn is not Teams markup. Adaptive Card Markdown does not support headings, tables, images, code fences, or blockquotes; use supported card elements when those structures are requested. Text-only content does not require a card.
Return the requested text, corrected string/object, or integration patch, preserving meaning and the known surface. Identify any missing runtime IDs or unverified client behavior. Posting is separate from formatting and requires the user's request or existing authorization.
Load the relevant format or metadata details only.
| Task | Reference |
|---|---|
| Bot Markdown/XML, card Markdown, hero cards, legacy text | MARKDOWN-HTML.md |
| Bot/card/Graph mentions; users, tags, teams, channels | MENTIONS.md |
| Graph HTML, code/emoji tags, attachments, permissions | GRAPH-CHATMESSAGE.md |
| Compact surface and syntax lookup | CHEATSHEET.md |
For card layout/actions, use teams-adaptive-cards if installed or the Teams card documentation. This text-formatting workflow does not depend on another skill being installed.
