Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# SecGuard AI Agent Extension — E2E Design

## Multi-Agent Architecture

SecGuard supports multiple AI Agent platforms through a shared-core + platform-specific design:

```
extension/
  shared/                          # Platform-agnostic content — SINGLE SOURCE OF TRUTH
    skills/                        # Agent Skills spec (agentskills.io) — same for all
      null-deref/SKILL.md
      buffer-overflow/SKILL.md
      memory-leak/SKILL.md
      injection/SKILL.md
    agent-body.md                  # Shared agent prompt (role, workflow, rules, output format)
    command-instructions.md        # Shared command workflow instructions
  opencode/                        # OpenCode-specific (thin frontmatter wrappers)
    opencode.json                  # Config: agent, permissions, plugin
    commands/secguard.md           # Frontmatter + {{include shared/command-instructions.md}}
    agents/security-auditor.md     # Frontmatter + {{include shared/agent-body.md}}
    tools/secguard_scan.ts         # TypeScript tool wrappers (Bun.$ → CLI)
    tools/secguard_index.ts
    tools/secguard_plan.ts
    tools/secguard_report.ts
    tools/secguard_status.ts

How to install

The exact contents, by fingerprint
mdr add dannyan/secguard-clang/extension/DESIGN.md@sha256:d578970edbb3ac0f

The line at the top of this page pins the label git:20260904.5b26b01, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
