Skill Codex
Run bounded HTTP(S) requests with curl when no narrower client can provide the needed evidence.
Agent-agnostic instructions, skills, agents, commands, and hooks adapted natively to coding-agent environments.
This repository also configures its own agents. See what MAINFRAME tells them →

Resolve credential identities, deliver secrets to a process, or administer entries through the MAINFRAME credential index and helper, without exposing values.
Skill Claude CodeCodex
Design, implement, debug, or review Node.js TypeScript services and Next.js server layers, including APIs, Server Actions, persistence, workers, and backend tests.
Skill Claude CodeCodex
Assess a consequential decision or readiness claim when mistaken acceptance could cause material harm, such as a production rollout, migration, or recovery. Not routine code review.
Skill Claude CodeCodex
Record an observed MAINFRAME or agent-harness fault, including missing skills, broken hooks, conflicting instructions, or adapter failures. Not application bug reports.
Skill Claude CodeCodex
Use an external coding-agent CLI only when the user or project agreement explicitly assigns that product work.
Skill Claude CodeCodex
Audit or repair project agent configuration when instructions conflict, skills are missing, or hooks, permissions, and tool policies misbehave. Not a routine setup check.
Skill Claude CodeCodex
Preserve unresolved project findings as structured tickets during ordinary work; establish a local ticket queue when none exists. Not an audit campaign or a way to defer unfinished work.
Skill Claude CodeCodex
Resolve dependent, disputed, or consequential external claims through authoritative sources, including compatibility comparisons and conflicting documentation. Not routine single-fact lookups.
Skill Claude CodeCodex
Assess existing tests and CI when their quality is questioned, regressions escape, checks are flaky or costly, or green results are misleading. Read-only audit; use mainframe-testing to write, run, or repair checks.
Skill Claude CodeCodex
Design, implement, debug, or review Go services, APIs, and workers, including transactions, concurrency, retries, and backend tests.
Skill Claude CodeCodex
Plan, query, integrate, or troubleshoot ClickHouse, including query cost, ingestion, schema changes, deletion, and recovery across production, shared test, and disposable targets.
Skill Claude CodeCodex
Plan, install, troubleshoot, secure, upgrade, or recover K3s clusters, including topology, networking, storage, and datastore backups. Not application-only changes or other Kubernetes distributions.
Skill Claude CodeCodex
Implement, adapt, or troubleshoot Keycloak OIDC login in a web application, including an admin connection screen, group-to-role mapping, account linking, and session lifecycle. Not Keycloak server deployment or login-page theming alone.
Skill Claude CodeCodex
Implement or troubleshoot application notifications and their settings UI, event routing, templates and delivery through Bitrix24, Telegram, webhooks, email or Web Push. Not one-off message sending, chat UI toasts or messaging-server deployment alone.
Skill Claude CodeCodex
Design, implement or repair an application's System/Diagnostics page with service health, resource metrics, logs and optional scoped container controls or data previews. Use for embedded operational consoles and misleading diagnostic states; not standalone monitoring-platform deployment or one-off infrastructure…
Skill Claude CodeCodex
Design, write, run, or repair tests and GitHub/GitLab CI during development. Use for test strategy, TDD, analysis tools, fixtures, local/CI boundaries, and verification evidence. Use mainframe-test-audit to assess an existing test system.
