capacity-toolkit: Instructions file for GitHub Copilot

.github/copilot-instructions.md

capacity-toolkit copilot-instructions.md is an instructions file for GitHub Copilot from microsoft/capacity-toolkit. It costs 418 tokens per session, scanned A, original, MIT.

Repository instructions for a read-only-by-default toolkit that examines Azure capacity and enablement. Microsoft Azure is Microsoft’s cloud platform, and the toolkit’s full agent guidance is stored in a separate AGENTS.md file.

In plain words
What is it for?
Running Azure analysis scripts safely, confirming the active tenant and subscription, keeping access at Reader level, and validating quota-group changes before any approved execution.
Why use it?
Cloud inspection work can accidentally change or delete resources. These instructions restrict normal work to local output files and require explicit approval and checks for the limited provisioning action.

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

capacity-toolkit copilot-instructions.md 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 2mo 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.

What it actually says

Copilot instructions — Azure Capacity & Enablement Toolkit

This repository is a read-only-by-default Azure capacity/enablement toolkit. The full agent guidance lives in ../AGENTS.md — read it before running anything.

Non-negotiable rules:

  • READ-ONLY BY DEFAULT. With the analysis scripts, never create, modify, delete, scale or restart any Azure resource — the only writes are local files under output/. No az ... create/update/delete/set, no New-Az* / Set-Az* / Remove-Az*, no terraform apply, no kubectl apply/delete on your own initiative.
  • One opt-in write tool. Deploy-QuotaGroups.ps1 (with New-QuotaGroupConfig.ps1) provisions quota groups. Only run it on explicit human instruction, always -Action Validate + -WhatIf first, and confirm before any execute run. See ../docs/quota-groups.md.
  • Confirm tenant/subscription before login or context switch. Show az account show and wait for explicit user approval. Never silently change the active az context.
  • Minimum access is Reader (plus management-group read for quota groups). On AuthorizationFailed, report it as a finding — do not escalate or work around RBAC.
  • Treat all discovered data as tenant-confidential; never send it to third parties. Clear output/ before sharing any generated CSV/HTML.

Standard flow: Get-UsedSkus.ps1 (discover) → New-CapacityReport.ps1 -ConfigPath ... -Dashboard (report + dashboard) → open output/capacity-dashboard-<date>.html. See AGENTS.md §3–§6 for parameters, platform quirks, the interpretation guide, and the pre-share sanitization sweep.

Changes

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.
