A tool for adding or removing users from a Microsoft app’s access list. It uses Microsoft Graph, Microsoft’s service for managing Microsoft 365 data and access, to resolve email addresses.

Use it to share an app with a list of users or remove their access from the current Microsoft App workspace.

It provides a guided access-control process, including confirmation and warnings when some email addresses cannot be resolved.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00033	$0.00855
Opus 5.5	$0.00013	$0.00342
Sonnet 5.5	$0.00007	$0.00171
Haiku 4.5	$0.00003	$0.00085

Security

Grade A, and why

share 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 5d ago.

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 — 96 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. Always confirm before share/unshare.

Adds or removes user access to the app in the current directory. The CLI resolves emails via Microsoft Graph; entries that don't resolve are returned as warnings (the RP call still succeeds for the resolved entries).

Workflow

Memory Bank → 2. Verify Project + Env → 3. Mode (share / unshare) → 4. Collect Emails → 5. Confirm → 6. Run → 7. Surface Partial-Success Envelope

Step 1: Check Memory Bank

Read memory-bank.md for app slug, GUID, and environment.

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

Step 3: Mode

Ask whether the user wants to share (add access) or unshare (remove access). Default to share unless the prompt obviously indicates removal.

Step 4: Collect Emails

Accept a comma-separated email list. Validate basic shape (user@domain) before passing through; don't try to resolve them yourself — ms handles Graph resolution and will return warnings for unresolved entries.

If the user passes Object GUIDs (already-resolved principals), pass them through as-is — the CLI accepts both forms.

Step 5: Confirm

Show the user exactly what will run, then ask for confirmation:

"About to share <app-name> with: [email protected], [email protected]. Confirm?"

Wait for explicit yes. Never auto-proceed — ACL changes affect production users.

Step 6: Run

Share:

$BIN app share "[email protected],[email protected]"

Unshare:

$BIN app unshare "[email protected],[email protected]"

The command reads the app ID from ms.config.json.

Step 7: Surface Partial-Success Envelope

The CLI returns a JSON envelope with partialFailure: boolean and warnings: []. When partialFailure: true:

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 is a skill published in the GitHub repository microsoft/managed-apps (36 stars, last pushed 3d ago), licensed MIT. It adds 33 tokens to every session and 855 once invoked, about $0.0001 per session on Opus 5.5. 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.
