share-link

A tool for creating, viewing, and cancelling URL-based access links for a Microsoft app. Opening a link grants the recipient reader access to that app.

In plain words
What is it for?
Create links for tenant-wide sharing, list active links, and revoke a link by its ID.
Why use it?
It lets you share app access without maintaining a list of named users. Cancelling a link also removes access for people who used it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

share-link scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.

📋 Shared Instructions: shared-instructions.md — Cross-cutting concerns.

Manages tenant-wide JIT-redemption links for a Microsoft App. The first time a recipient opens a share link they are automatically granted the Microsoft App Reader role at the app scope — no explicit principal list required.

Three sub-commands:

Command Purpose
ms app share link create Generate a new share link URL
ms app share link list List all active share links
ms app share link revoke Revoke a link by ID (removes redeemers' access)

Note: Share links are for distributing play access tenant-wide. For granting named users play or edit access, use /share instead.

Workflow

  1. Memory Bank → 2. Verify Project + Env → 3. Mode → 4. Run → 5. Surface Result

Step 1: Check Memory Bank

Read memory-bank.md per shared-instructions.md for the app's environment/app identifiers, if recorded.

Step 2: Verify Project + Env

test -f ms.config.json || { echo "Not in a Microsoft App workspace."; exit 1; }
BIN=ms
$BIN auth status                                         # must report the expected UPN

Both --app and --environment-id can be supplied explicitly to run from outside a project directory. When ms.config.json is present its appId and environmentId are used automatically.

Step 3: Mode

Ask the user which operation they want if not already clear from context:

  • create — generate a new share link.
  • list — show all active share links.
  • revoke — delete a share link by ID (also removes access for past redeemers).

Step 4: Run

Create
$BIN app share link create

Flags:

Flag Required Description
--app No App name override. Defaults to appId in ms.config.json.
--environment-id / -e No Environment ID override. Defaults to ms.config.json.
--json No Machine-readable envelope: { success, appName, appShareLinkId, shareLinkUrl }.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

share-link is a skill published in the GitHub repository microsoft/managed-apps (5 stars, last pushed 5d ago), licensed MIT. It adds 52 tokens to every session and 1,462 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
