Investigate a question against high-trust primary sources and capture the findings as a Markdown file in the repo. Use when the user wants a topic researched, docs or API facts gathered, or reading legwork delegated to a background agent.
Audit an aggregate implementation diff or proposed remediation obligation against resolved architecture and current architectural authorities. Report architecture drift, unresolved architectural changes, and boundary violations without modifying code, docs, ADRs, or the Living Entity Wiki.
Internal continuation of $review-spec that maintains durable Root Blocker state, applies validated scope corrections without erasing history, and hands only active architecture-conforming remediation to $to-tickets.
Review a verified completed Spec against its persisted deterministic Spec contract, using ownership-scoped Standards review, independent Spec/Architecture review, and conditional saturation only when convergence risk is demonstrated.
Configure this repo for the engineering skills — set up its issue tracker, triage label vocabulary, and domain doc layout. Run once before first use of the other engineering skills.
Build or validate the deterministic Spec obligation manifest and distinguish Spec-owned changes from inherited integration history for Spec verification and review.
Invoked only by $review-spec when its Exit Gate authorizes progression. Merges the spec branch into main or directly closes branchless Specs, resumes interrupted post-completion cleanup safely, cleans up the branch and any remediation Spec Review, and reconciles completion with every governing Wayfinder map.
Create and manage Architectural Decision Records (ADRs) in docs/adr/. Owns ADR format, numbering, naming, lifecycle transitions, content mutability, realization maintenance, supersession, and Living Entity Wiki synchronization triggers.
Invoked only by $to-specs when a Wayfinder map already has one or more in-progress Spec handoffs — recover derived and remediation Specs, apply newly resolved decision deltas, and amend them without duplicating previously consumed decisions.
Invoked only by $to-tickets during remediation re-invocation — reconcile a Spec Review or existing Spec against linked tickets and return only the actionable ticket delta.
Turn an explicit planning source and current codebase understanding into one or more implementation specifications and publish or update them in the configured issue tracker.
Break an explicit plan, spec, review, or other invocation source into tracer-bullet tickets, each declaring its blocking edges, and publish them to the configured tracker.
Performs diff hygiene, contract-impact closure, syntax/format/static typing verification, and targeted testing on Python files modified in the workspace or active ticket.
Independently verify Root Blocker closure for a Spec Review remediation ticket across the authoritative surfaces governed by the root, in the fresh non-mutating verifier subagent dispatched by $implement-ticket after explicit human authorization.
Perform authorized Spec-wide verification against a deterministic Spec contract, run fail-fast deterministic gates, establish complete evidence-backed per-cell proof, repair Spec-owned failures, and record a passing receipt for the exact final HEAD.
Plan a huge chunk of work — more than one agent session can hold — as a shared map of decision tickets on your issue tracker, and resolve them one at a time until the way to the destination is clear.
Scan the full Living Entity Wiki for recurring patterns across Rejected Approaches and Open Questions that no single entity states alone. Produces higher-inference hypotheses for human review and never mutates authoritative or wiki state.
