SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Internal harness for meta-matrix path-2 probing. The probe is invoked only by skills/meta-matrix-skill-invocation/ (row S4) via the Skill tool and by itself emits one sentinel and stops; quit and relaunch Claude Code from the repo root so it is discovered at session start. Not intended for direct user invocation.

Core Features & Use Cases

  • Dual-sentinel design to determine if bang-injection substitution occurs in a forked skill context.
  • Clear guidance on interpreting LITERAL vs THRU_INJECTION sentinels to disambiguate substitution behavior.
  • Structured reporting to downstream agents for meta-matrix evaluation and session-start discovery.

Quick Start

Use the fork-probe to surface whether substitution fired by a forked skill's path.

Frequently Asked Questions about meta-matrix-fork-probe

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I detect if bang injection substitution occurs in a forked skill body?▼

You need a controlled sentinel flow and a forked skill context to probe path disambiguation. The probe is invoked indirectly by meta-matrix invocation tooling at session start, requiring you to quit and relaunch Claude Code from the repo root for discovery.

How does a dual-sentinel probe work for testing fork-path substitution in matrix tests?▼

A dual-sentinel probe works by emitting one sentinel and halting, then comparing paired sentinels to surface whether substitution fired. It distinguishes LITERAL sentinels from THRU_INJECTION sentinels to clarify forked path substitution behavior for downstream agents.

Does the meta-matrix fork probe require direct user invocation to test substitution?▼

No, the meta-matrix fork probe does not require direct user invocation. It is an internal harness invoked only by the meta-matrix skill invocation tooling via the Skill tool, emitting one sentinel and stopping to report substitution results downstream.

Why is my fork-path substitution probe not being discovered at session start?▼

Your fork-path substitution probe may not be discovered because it requires session-start discovery from the repo root. You must quit and relaunch Claude Code from the repository root so the meta-matrix tooling can properly detect and invoke the probe.

What is the best way to interpret LITERAL vs THRU_INJECTION sentinels in matrix testing?▼

The best way to interpret LITERAL vs THRU_INJECTION sentinels is to compare the paired sentinels directly. LITERAL indicates no substitution occurred, while THRU_INJECTION confirms the bang injection fired within the forked skill body during the meta-matrix probing scenario.
