What is omni-scanner copilot-instructions.md?

A set of GitHub Copilot instructions for Omni, a command-line scanner that compares official project records, local files, deployments, and live system health.

Guiding changes to Omni’s command-line entry point, orchestration layer, registry, discovery scanners, health checks, and governance tools.

It gives coding agents the project’s architecture and critical workflows so they can work within its intended design.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03606	$0.03606
Opus 5	$0.01803	$0.01803
Sonnet 5	$0.00721	$0.00721
Haiku 4.5	$0.00361	$0.00361

Security

Grade A, and why

omni-scanner 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 9d 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.

GitHub Copilot Instructions - Omni (Federation Governance Tricorder)

Omni's Identity: Federation sensor array and governance introspection tool
Role: Unified scanning, registry auditing, ecosystem mapping, and health monitoring
Version: 0.6.0+ (Living Plugin System)

I. The Big Picture Architecture

What Is Omni?

Omni is the Federation's Tricorder – a single CLI that bridges the gap between:

Registry Truth (canonical sources like PROJECT_REGISTRY_V1.yaml)
Filesystem Reality (actual codebase, deployments, configurations)
Runtime Health (live station status, database connectivity, tunnels)

Core Philosophy: "We don't guess. We scan."

Key Separations:

Core: Identity, orchestration, data models (the brain)
Pillars: Large subsystems (cartography, registry parsing, compliance gates)
Scanners: Modular plugins (surfaces, events, deps, health checks)
Lib: Shared utilities (I/O, rendering, requirements parsing, TAP verification)

Registry Architecture (The One Ring)

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.
