AI & ML
AI & ML agent skills cover the machine-learning workflow itself: writing and evaluating prompts, building RAG pipelines, running evals, and wiring up model APIs. Each one is a SKILL.md file your agent loads on demand, so the know-how travels across Claude Code, Cursor, and 60+ agents.

kryptobaseddev Bundle Skill EvaluatorEval-driven quality evaluation, regression detection, and auto-improvement of Agent Skills. Auto-generates challenging test cases unique to the target skill from its SKILL.md, runs A/B benchmarks (with-skill vs without-skill or version-vs-version), grades outputs with programmatic + LLM-judge assertions, aggregates pass-rate/token/latency deltas, detects regressions across iterations, proposes generalized improvements grounded in failure transcripts, and optimizes the trigger `description` field via train/validation splits. Use whenever the user wants to evaluate, benchmark, A/B test, grade, score, regression-test, fine-tune, harden, optimize, improve, iterate on, or measure the quality of any skill — even if they only say "test this skill", "is this skill any good", "rate this skill", "tune the description", "did my edits make it worse", or "make this skill better".
-
kryptobaseddev Bundle Skill ValidatorValidate any Agent Skill against the agentskills.io specification plus project- or skill-local rule overrides. Use when auditing a skill folder for compliance, preparing a skill for distribution, checking PR-changed skills in CI, enforcing custom frontmatter rules, or verifying that a skill's `metadata`, `compatibility`, body length, and file references all meet the spec. Every rule is config-driven — point the validator at a YAML config to customize allowed/required/forbidden frontmatter fields, regex patterns for metadata values, timestamp formats, body thresholds, and placeholder bans. Triggers on: 'validate skill', 'check skill compliance', 'audit SKILL.md', 'lint skill folder', 'verify skill against agentskills.io', 'is this skill spec-compliant'.

kryptobaseddev Bundle 3d Parametric ModelsModel parametric 3D geometry as code and edit mesh files programmatically. OpenSCAD (.scad) is the core for scripting solid models with named parameters; pair it with a Python mesh toolkit (trimesh/manifold3d) to inspect, repair, measure, scale, boolean, convert, and batch-generate STL/3MF — then optionally slice and print (Bambu Lab / OrcaSlicer). Use whenever the user wants to create, generate, design, model, script, parametrize, modify, repair, convert, or batch-produce a 3D model, part, or mesh: write or improve OpenSCAD/.scad code, turn a description into an STL or 3MF, make a part with adjustable/customizable dimensions, fix a non-watertight or non-manifold STL, scale/cut/boolean/convert an existing STL, render many variants, or design something to 3D print. Trigger even if they only say 'OpenSCAD', '.scad', 'STL', '3MF', 'edit/repair this STL', 'parametric model', 'CAD', 'make me a bracket/box/holder/knob', 'design for 3D printing', 'Bambu', 'Fusion 360', or 'Blender'. Bridges Fusion 360 and Blender.

igrlebed Skill Lazyweb Quick SearchUse the Lazyweb search MCP tool directly for quick industry references before designing or changing UI. Does not generate a report. Use when the agent needs a lightweight best-practice check from real app screenshots, wants to inspect search coverage, or should grab a few references before building. Trigger on: "quick search", "search Lazyweb", "use lazyweb_search", "quick industry references", "check examples before designing", "look up UI references first".

-
iris-ymy Bundle Codex RehomeUse when the user wants to migrate, back up, restore, or reproduce a Codex Desktop workspace between Mac and Windows computers, preserve Codex before reinstalling an OS, or bridge Claude Code / Claude Desktop agent history into a Codex-readable handoff; relevant for Codex sessions, projects, skills, plugins, path mappings, restore verification, and Claude-to-Codex migration checks.

parvez3019 Bundle Secure ServiceApply security controls at every trust boundary of a service. Covers the OWASP API Security Top 10 with object- and function-level authorisation first, service-to-service authentication with mTLS or signed tokens, input validation and injection prevention, secrets handling, output and error hygiene, PII classification and data protection, rate limiting of sensitive business flows, and supply-chain integrity through pinning, SBOMs and provenance. Use when writing or reviewing a handler, a client call, a query, an authorisation check, a dependency change, or anything touching credentials, tokens, or personal data; also when the user says 'security', 'auth', 'vulnerability', 'secrets', 'OWASP', or 'threat model'. This skill governs trust boundaries — not contract shape (see api-contracts), not failure behaviour (see resilience-patterns).
-
parvez3019 Bundle Domain ModellingDesign the classes that carry business meaning, using tactical domain-driven design. Covers entities versus value objects, aggregate boundaries justified by a named invariant, domain services, domain events, factories, the ubiquitous language, making illegal states unrepresentable, and keeping behaviour on the type that owns the rule rather than in a service. Use when creating or changing a domain class, choosing an aggregate boundary, deciding whether something is an entity or a value, naming a domain concept, or when the user says 'domain model', 'DDD', 'aggregate', 'entity', 'value object', 'domain class', or 'business rules'. This skill governs the shape of domain types — persistence craft belongs to data-access, read models and consistency to cqrs-and-consistency, service-level boundaries to service-boundaries.
-
parvez3019 Bundle Cqrs And ConsistencyDecide how reads are served, how far they may lag behind writes, and who owns each piece of data. Covers the five levels of command-query separation and when each is earned, read models and projections with a stated staleness budget, rebuildability, event sourcing and its permanent costs, read-your-writes, and data ownership between services. Use when adding a read model or projection, choosing between one model and separate read and write paths, evaluating event sourcing, deciding whether a service may hold a copy of another's data, or when the user says 'CQRS', 'read model', 'projection', 'event sourcing', 'eventual consistency', or 'stale data'. This skill governs the read path and the consistency model — domain types belong to domain-modelling, query and transaction craft to data-access.
