Skill Claude CodeCodex
Use when: formalizing, routing, validating, promoting, or retiring an Arcanum discipline so a recurring cross-capability practice gets a card, catalog entry, and a hardening route without claiming sigil or spell authority.
Skill Claude CodeCodex
Composed Arcanum spell: discovery-to-inventory.
Skill Claude CodeCodex
Use when: validating or designing an Arcanum dispatch route that chains sigils, spells, owner capabilities, handoffs, gates, observability, techniques, and optional boundary/evidence contracts.
Skill Claude CodeCodex
Use when: reducing a broad model, architecture, design, implementation plan, or workflow into the smallest coherent concept unit that still fits the user's target context and can recompose into the larger system.
Skill Claude CodeCodex
Use when initializing, running, looping, validating, reporting, or observing repeatable profile-aware development experiments for Arcanum spells and sigils through native skill/subagent execution or explicit legacy runtime adapters.
Skill Claude CodeCodex
Subagent dispatch that PROPOSES and pre-registers a falsifiable experiment — the designer authors a success/failure criterion fixed BEFORE any run and the skeptic validity-checks it, producing a frozen criterion.md. Running the probe and adjudicating survived-vs-falsified is a SEPARATE downstream step, not part of…
Skill Claude CodeCodex
Use when: creating or updating a concise glossary for a feature, workflow, product area, or bounded project scope from source evidence.
Skill Claude CodeCodex
Guide a user through a software architecture target by composing context selection, structure inspection, optional translation, explanation sequencing, active-understanding validation, and User-ledger update proposals.
Skill Claude CodeCodex
Use when: creating or evolving a project-agnostic implementation layering model for a feature, capability, product workflow, research workflow, infrastructure change, or system improvement. Builds layers from minimum working unit proof to progressive hardening using value/cost layer-boundary heuristics.
Skill Claude CodeCodex
Composed Arcanum spell: implementation-readiness.
Skill Claude CodeCodex
Use when: running one-question-at-a-time interviews with pluggable modes, evidence-backed prompts, and artifact updates after each answer.
Skill Claude CodeCodex
Use when: installing or maintaining a repository-local compiled knowledge inventory that lets agents ingest once, index, tag, query, lint, and reuse context across sigils.
Skill Claude CodeCodex
Use when selecting and running invoke template validation prompts in Codex, including picking a task by ID, template, complexity, or the next unrun prompt and saving the Invoke Result output.
Skill Claude CodeCodex
Use when: turning development intent into governed define, design, plan, handoff, or refresh artifacts before lifecycle execution.
Skill Claude CodeCodex
Necronomicon is the repository-local knowledge harness for Arcanum. Its MVP is an Inventory And Ontology Substrate Loop: answer what the repository already knows, what is source-backed, what is only a candidate, what conflicts, and which owner should handle the next step.
Skill Claude CodeCodex
Use when: installing or verifying the standard sigil observability package in a repository so sigils can append post-run JSON telemetry and reflection state.
Skill Claude CodeCodex
Observed Invocation Loop wraps Arcanum-managed skill, sigil, and spell invocations with a guaranteed post-run observability handoff. It turns each managed invocation into a safe invocation envelope, appends exactly one telemetry signal, updates reflection counters, and routes to reflection when configured thresholds…
Skill Claude CodeCodex
Ontology Harness composes inventory, ontology-vault, and context-builder so a repository can turn vault-like knowledge material into a reusable ontology governance layer.
Skill Claude CodeCodex
Use when: mapping, distilling, validating, or evolving a governed knowledge vault with roles, confidence, premises, sessions, edge rules, branch-aware ontology, and ontology conventions.
Skill Claude CodeCodex
Publication Research Pipeline composes Arcanum research capabilities into a governed path from research question to publishable paper package. It keeps source understanding, evidence execution, claim adjudication, paper rewriting, and export packaging in separate owner lanes.
Skill Claude CodeCodex
Use when: turning a vague refinement target, design concern, folder, idea, repository area, or existing work-pack into a refined seed, design, or non-executed plan through the Arcanum refinement loop.
Skill Claude CodeCodex
Composed Arcanum spell: repository-harness.
Skill Claude CodeCodex
Use when: converting research protocols into validated run schemas, JSONL fixture checks, objective/metric calculations, result summaries, and claim-adjudication readiness without running or overclaiming live experiments.
Skill Claude CodeCodex
Use when: turning a paper, source corpus, or research question into a governed local research tower with source-first claims, notation bridge, glossary, definitions, distills, related-work map, bridge decisions, residue, and a final learning pack.
