gepa-ai Bundle

Automatically improve any text artifact that can be scored — prompts, programs/code, configs, specs, regex/SQL/schemas, agent scaffolds, or encoded search solutions — with optimize_anything, an LLM-driven optimization API: a search backend repeatedly proposes better versions from execution feedback and an evaluator you provide assigns the score (an objective metric or an LLM-as-judge for subjective tasks). optimize_anything is one interface across several optimizer backends — GEPA (reflective evolutionary search, the default), AutoResearch, MetaHarness — plus a best-of-N baseline: write the evaluator once and switch backend with a single argument. Use whenever a task needs auto-optimizing, tuning, or searching over text with any quality signal (accuracy, pass rate, latency, cost, judge rating); when building an evaluator + proposer loop; when running GEPA; or when comparing optimizers. The candidate can be any string an evaluator can grade, scored on one problem or generalized across many.

geekswamp Bundle

Generate deterministic, high-quality Go unit tests using table-driven patterns, infrastructure mocks, and project-specific helpers. Make sure to use this skill whenever the user mentions generating tests, writing test cases, increasing test coverage (aiming for ≥80%), or mocking dependencies like SQL (sqlmock), Redis (miniredis), or HTTP (Gin). It is optimized for table-driven test structures, deterministic data, and the mandatory use of the project's 'testutil' package. Use it for requests to create *_test.go files, implement unit tests for services or repositories, and ensure robust coverage of success and error paths.

appautomaton Bundle

Turn a large task into a persistent plan file and a trackable Issue CSV (local files, not an external issue tracker), then execute the issues autonomously with per-row status updates. Use when work must survive across sessions or hand off between agents, when you need an auditable record of multi-step execution, or to resume a plans/ and issues/ pair from an earlier session. Do not use for single-session tasks that your harness's built-in plan or todo tracking already covers.

Behavioral analysis of a sample executed in an isolated VM. Use after triage when runtime behavior, C2 traffic, dropped files, persistence, or injection must be observed.

The analyst runs the VM; Claude never executes the sample.
