- solweaverjay7793/solweaverRun Sol-led software development in auto, solo, solo-reviewed, or team modes, with GPT-5.6 Sol owning planning, implementation or delegation, integration, verification, and delivery; terra_worker and luna_worker providing bounded implementation; bundled test-driven-development enforcing RED-GREEN-REFACTOR for production-code behavior changes; and solweaver_reviewer providing one fresh final-strict review at a declared assurance-unit boundary. Use when explicitly invoked for any software-development task, including small fixes; for software-development prompts beginning with Goal: or /goal; or when the user requests Sol-only work, a software team, agents, subagents, parallel work, or delegated implementation. Do not use for general questions, research, writing, or operations-only requests.TestingNo warnings★ 60↓ —
- red-teamgaasher/Agent-Loop-SkillsUse when the user wants to adversarially stress-test a guardrail, classifier, prompt, or API they own or are authorized to test, to surface the distinct ways it fails. Generates adversarial inputs, runs them through the target and a ground-truth oracle, logs every target-vs-oracle disagreement as a failure de-duplicated by technique class, and loops until rounds stop surfacing new classes. Produces a catalogue of distinct, reproducible failures — the attacker half of a find→fix setup. Not for patching the target, and not for attacking systems the user does not own or have permission to test.TestingNo warnings★ 178↓ —
- optimize-loopgaasher/Agent-Loop-SkillsUse when the user wants to iteratively improve an artifact under a hard correctness bound while minimizing a measured cost — refactoring a code module to cut complexity while its test suite stays green, OR speeding up a SQL query while it returns the same rows. Each iteration applies one focused change, checks a correctness gate that must pass, measures a metric that must drop, and keeps the change only if both hold, else reverts; loops to a plateau or budget. Not for adding features, fixing bugs, or any change that is allowed to alter behaviour or results.TestingNo warnings★ 178↓ —

- power-analysisgaasher/Agent-Loop-SkillsUse when the user is planning a two-arm comparison (an A/B test, a simple RCT, a behavioral study, or a two-model/two-config evaluation) and needs to size it and preregister it before collecting data — finding the per-group sample size that hits target statistical power for the smallest effect worth detecting, auditing the design against a validity checklist, and locking it in a preregistration. Only for a single two-arm comparison with one primary outcome. Not for factorial, repeated-measures, clustered/multilevel, time-series, adaptive, or survival designs; not for analyzing data already collected; not for choosing the outcome or manipulation from domain knowledge.TestingNo warnings★ 178↓ —
- llm-testingEyadkelleh/awesome-skills-securityComprehensive LLM security testing prompts for bias detection, data leakage, alignment testing, and adversarial prompt resistance.TestingNo warnings★ 393↓ —
- blue-teamgaasher/Agent-Loop-SkillsUse when the user has concrete failing cases in code or a guardrail/classifier/filter/prompt/API they own — a red-team failure catalogue OR a CI/CD test-failure report (failing pytest/JUnit tests) — and wants the target patched until those failures are closed without breaking what already works. It points straight at the failed cases (normalize any source with tools/ingest.py), fixes one root-cause class per iteration, and re-checks with tools/verify.py — oracle mode against a red-team oracle, or tests mode against the test suite — keeping a patch only if it closes a class while nothing that passed before regresses, else reverting; loops until every class is closed (dry) or the budget runs out, then opens a pull request with the patch set. The defensive fixer half of a find→fix setup. Not for discovering new failures (that is red-team), and not for editing the oracle, tests, or holdout that define ground truth.TestingNo warnings★ 178↓ —

- go-testingcxuu/golang-skillsUse when writing, reviewing, or improving Go test code — including table-driven tests, subtests, parallel tests, test helpers, test doubles, and assertions with cmp.Diff. Also use when a user asks to write a test for a Go function, even if they don't mention specific patterns like table-driven tests or subtests. Does not cover benchmark performance testing (see go-performance).TestingNo warnings★ 181↓ —
