Powershell-Copilot-Standards: Command for GitHub Copilot

.github/prompts/security-review.prompt.md

security-review is a command for GitHub Copilot from fadwen/Powershell-Copilot-Standards. It costs 7 tokens per session (308 once invoked), scanned A, original, MIT.

A security review for PowerShell code that checks credentials, input handling, errors, access controls, encryption, audit trails, and common injection risks. It can also compare the code with compliance frameworks such as GDPR or HIPAA.

In plain words
What is it for?
Use it to review scripts and functions for hardcoded credentials, SQL or command injection, unsafe file paths, weak error handling, privilege problems, and compliance gaps.
Why use it?
It helps find ways code could expose secrets, accept unsafe input, reveal sensitive errors, or fail required security controls.

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

security-review 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 1mo 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

Perform comprehensive security analysis on this PowerShell code:

Selected Code:

${selection}

Analysis Context:

  • Compliance framework: ${input:complianceFramework:SOX,GDPR,HIPAA,PCI-DSS,General:General}
  • Environment: ${input:environment:Development,Testing,Production:Production}
  • File: ${fileBasename}
  • Project: ${workspaceFolderBasename}

Security Review Areas:

  1. Modern Credential Handling

    • Check for [PSCredential]::new() usage vs legacy New-Object
    • Validate SecureString implementation
    • Identify hardcoded credentials or API keys
  2. Input Validation

    • Verify appropriate parameter validation (not over-validated)
    • Check for SQL injection in dynamic queries
    • Validate file path and command injection risks
  3. Error Handling Security

    • Ensure $_ usage in catch blocks (not $Error manipulation)
    • Check for information disclosure in error messages
    • Validate proper exception propagation
  4. Enterprise Security Patterns

    • Audit trail implementation with correlation IDs
    • Access control and privilege verification
    • Data encryption and protection patterns
  5. Compliance Alignment

    • Framework-specific requirements validation
    • Data handling and retention compliance
    • Security logging and monitoring requirements

Provide specific remediation recommendations with corrected code examples following modern PowerShell best practices.

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.
