Instructions file

Instructions for cosmix/loom, covering claude.md, project overview, build commands, architecture and source layout (loom/src/).

cosmix/loom

Agent

Read-only advisory agent for debugging and repeated failures. Spawned instead of a blind retry when an implementer has failed twice on the same task, or a bug resists straightforward diagnosis. Returns a root-cause diagnosis plus one concrete next step.

cosmix/loom

Agent

Read-only code review agent for comprehensive review of code quality, security, architecture, and best practices. Cannot modify files.

cosmix/loom

Agent

Forwarding shim for the loom codex implementation lane. Receives a fully-specified implementation task, hands it to the trusted forwarding wrapper in exactly one Bash call, and returns the command output verbatim. Never reads, edits, or implements anything itself.

cosmix/loom

Agent

Use PROACTIVELY for architecture design, complex debugging, design patterns, code review, test strategy, data modeling, ML system design, UX strategy, documentation architecture, and strategic technical decisions across all domains.

cosmix/loom

Agent

Primary implementation agent for all coding work - features, bug fixes, tests, data pipelines, ML training, infrastructure code, documentation, UI components, and queries. Handles routine implementation across all technical domains.

cosmix/loom

Skill Claude CodeCodex

Pressure-test a loom plan and write a review for the plan's author. Trigger when the user invokes $pressure followed by a plan path. The argument after $pressure is the plan file path.

cosmix/loom

Command

Address the pressure-test review for a plan.

cosmix/loom

Command

Distill important session insights into doc/loom/knowledge.

cosmix/loom

Command

Pressure-test a plan with an agent team.

Skill Claude CodeCodex

Web accessibility patterns, WCAG compliance, and inclusive design. Use when implementing accessible UI, keyboard navigation, screen reader support, focus management, semantic HTML, ARIA patterns, or auditing for compliance.

cosmix/loom

Skill Claude CodeCodex

Designs RESTful APIs, GraphQL schemas, and RPC interfaces for consistency, usability, and scalability. Use when defining endpoints, resource models, HTTP semantics, pagination, versioning, or RPC service contracts.

cosmix/loom

Skill Claude CodeCodex

Document REST APIs with OpenAPI/Swagger specifications, endpoint references, authentication flows, error handling, and SDK guides. Use for API reference docs, Swagger specs, interactive explorers, and client library documentation.

cosmix/loom

Skill Claude CodeCodex

GitOps continuous delivery with Argo CD for Kubernetes. Use when implementing declarative GitOps workflows, application sync/rollback, multi-cluster deployments, progressive delivery, or CD automation.

cosmix/loom

Skill Claude CodeCodex

Authentication and authorization patterns including OAuth2, JWT, RBAC/ABAC, session management, API keys, password hashing, and MFA. Use for login flows, access control, identity management, tokens, permissions, and API key authentication. Do not use for vulnerability scanning (use loom-security-scan), audits…

cosmix/loom

Skill Claude CodeCodex

Background job processing patterns including job queues, scheduled jobs, worker pools, retry strategies, and delivery guarantees. Use when implementing async processing, ETL pipelines, ML training jobs, cron schedules, or dead letter queues.

cosmix/loom

Skill Claude CodeCodex

Generates before/after verification pairs for loom plans. Proves a stage actually changed system behavior by capturing state before and after implementation. Use for delta-proof verification of new commands, endpoints, modules, or bug fixes.

cosmix/loom

Skill Claude CodeCodex

Caching strategies for performance optimization — cache-aside, write-through, write-behind, TTL policies, eviction, and stampede prevention. Use for Redis/Memcached, CDN caching, database query caching, ML model caching, and distributed cache design.

cosmix/loom

Skill Claude CodeCodex

Designs and implements CI/CD pipelines for automated testing, building, deployment, and security scanning across GitHub Actions, GitLab CI, Jenkins, CircleCI, and cloud-native platforms. Covers pipeline optimization, test integration, artifact management, and release automation.

cosmix/loom

Skill Claude CodeCodex

Strategies and patterns for safe code migrations and upgrades. Use when upgrading frameworks, migrating between technologies, handling deprecations, planning incremental rollouts, or applying automated codemods.

cosmix/loom

Skill Claude CodeCodex

Comprehensive code review covering correctness, maintainability, performance, security, and best practices. Use for PR reviews, pre-merge audits, architecture and design critique, and actionable reviewer feedback.

cosmix/loom

Skill Claude CodeCodex

Concurrency and parallelism patterns for multi-threaded and async code. Use when implementing async/await, parallel processing, thread safety, worker pools, channels, or debugging race conditions and deadlocks across Rust (tokio), Python (asyncio), TypeScript, and Go.

cosmix/loom

Skill Claude CodeCodex

Cloud-native infrastructure management with Crossplane via Kubernetes APIs. Use for building internal platform APIs, composite resources, XRDs, compositions, claims, provider configuration, and multi-cloud self-service provisioning.

cosmix/loom

Skill Claude CodeCodex

Data validation patterns covering schema validation, input sanitization, output encoding, and type coercion. Use for form/API validation with Zod/Pydantic/Joi/JSON Schema, XSS and injection prevention, constraint checks, data pipeline and ML feature validation.
