apex-accelerator: Instructions file for GitHub Copilot

.github/instructions/governance-discovery.instructions.md

apex-accelerator governance-discovery.instructions.md is an instructions file for GitHub Copilot from jonathan-vella/apex-accelerator. It costs 804 tokens per session, scanned A, original, MIT.

Rules for discovering Azure Policy constraints from the live Azure environment or an approved scheduled snapshot. It requires stopping when policy information cannot be retrieved instead of making assumptions.

In plain words
What is it for?
Use it as a mandatory prerequisite for Azure governance discovery and infrastructure planning when policy assignments, effects, or inherited management-group rules must be known.
Why use it?
Azure policies can be inherited and may differ from what a basic lookup shows. Using incomplete or guessed rules can lead to deployment failures.

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

apex-accelerator governance-discovery.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 6d 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Governance Discovery Instructions

CRITICAL: Governance constraints MUST come from the live Azure environment — either directly through discover.py during the current run, or indirectly through the approved scheduled workflow baseline generated from live Azure and committed under .github/data/governance-policy-baseline.json.gz. GATE: This is a mandatory gate. If Azure connectivity fails or policies cannot be retrieved during live discovery, STOP and inform the user. Do NOT generate governance constraints from assumptions. Single exception: the user may explicitly choose the shipped alz-corp-default baseline as assumed governance (see baseline-check.md). It must be labelled assumed and not tenant-verified in every artifact, and the Step 3.5 review stays mandatory. Do NOT accept arbitrary static files as governance input — only the approved workflow output file (.github/data/governance-policy-baseline.json.gz) is valid for cached baseline mode.

Why This Matters

Assumed governance constraints cause deployment failures. Example:

  • Assumed: 4 tags required (Environment, ManagedBy, Project, Owner)
  • Actual: 9 tags required via Azure Policy
  • Result: Deployment denied by Azure Policy

Management group-inherited policies are invisible to basic queries. Use REST API (not az policy assignment list) to capture all inherited policies.

Discovery Runs Through discover.py

04g-Governance runs the deterministic discover.py (live) or render_cached_governance.py (approved baseline). The script verifies ARM connectivity, queries all effective assignments via REST (including MG-inherited), drills into Deny/DeployIfNotExists definitions, classifies effects and writes 04-governance-constraints.json. Do not re-create or hand-populate that file.

The authoritative output contract is tools/schemas/governance-constraints.schema.json and the skill's field reference.

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.
