microsoft/power-platform-skills is a plugin marketplace containing reusable skills, agents, and commands for developing with Microsoft Power Platform. Developers use it to build and deploy Power Pages sites, model-driven Power Apps, and related solutions through Claude Code or GitHub Copilot. The catalogue entries are the marketplace's included skills, agents, plugins, and other agent components.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.
git clone --depth 1 https://github.com/microsoft/power-platform-skillsnpx agentmods add skills/microsoft/power-platform-skills/add-office365Wrote this? Show the measurements
A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 6 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
- medium Prompt Injection · line 122 Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.Fix: Remove the large whitespace padding (blank-line blocks or long space runs) and review any content hidden below or to the right of it. Keep skill files compact and reviewable so no instructions can be
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 | $0.01339 |
| Opus 5 | $0.00016 | $0.00669 |
| Sonnet 5 | $0.00007 | $0.00268 |
| Haiku 4.5 | $0.00003 | $0.00134 |
Grade A, and why
add-office365 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 10d 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 — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Add Office 365 Outlook
Workflow
- Check Memory Bank -> 2. Add Connector -> 3. Review Generated Service -> 4. Configure -> 5. Build -> 6. Update Memory Bank
Step 1: Check Memory Bank
Check for memory-bank.md per shared-instructions.md.
Step 2: Add Connector
First, find the connection ID (see connector-reference.md):
Run the /list-connections skill. Find the Office 365 Outlook connection in the output (API name contains office365). If none exists, direct the user to create one using the environment-specific Connections URL — construct it from the active environment ID in context (from power.config.json or a prior step): https://make.powerapps.com/environments/<environment-id>/connections → + New connection → search for the connector → Create.
pa app add data-source --connector office365 -c <connection-id>
Step 3: Review Generated Service
The generated service file (src/generated/services/Office365OutlookService.ts) is large. Use Grep to find specific methods instead of reading the entire file:
Grep pattern="async \w+" path="src/generated/services/Office365OutlookService.ts"
Key methods (sorted by common usage):
Calendar Operations
| Method | Purpose | Key Parameters |
|---|---|---|
GetEventsCalendarViewV2 |
Get events in a date range | calendarId, startDateTimeOffset, endDateTimeOffset |
V3CalendarPostItem |
Create a calendar event | table (calendar ID), item (CalendarEventHtmlClient) |
CalendarDeleteItem |
Delete an event | table (calendar ID), id (event ID) |
CalendarPatchItem |
Update an event | table, id, item |
V2CalendarGetTables |
List available calendars | (none) |
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.

add-office365 is a skill published in the GitHub repository microsoft/power-platform-skills (851 stars, last pushed today), licensed MIT. It adds 33 tokens to every session and 1,339 once invoked, about $0.0002 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 2026-08-30.
