Fixture for the YARA-lite signature engine. Carries a small bash reverse-shell script (YR1_bash_reverse_shell) and a minimal PHP eval webshell (YR2_php_eval_shell) so the integration test can assert both critical signature matches in a single scan.

Skill (signatures)

This skill carries known-bad signature payloads. The scripts/ tree holds the actual indicators; SKILL.md is intentionally bland so the test sees the signature finding without taxonomy crosstalk.

create-skill-eval

astra-sh/qvr

Author a frozen, graded eval harness for ONE inner skill and freeze it inside that skill as a conformant eval/ directory (scenarios + deterministic evaluator + rubric + fixtures + HARNESS.md manifest). The eval content is skill-specific; this skill is the reusable methodology that produces it. Its output is consumed read-only by optimize-skill-loop. Use BEFORE optimizing — when a skill needs a graded before/after harness built. Trigger phrases: "build an eval harness for <skill>", "create a skill eval", "instrument <skill> with a frozen grader", "write scenarios and a rubric for <skill>".

optimize-skill-loop

astra-sh/qvr

Deterministic outer-loop optimizer for a skill that already carries a frozen eval (produced upstream by an eval source such as create-skill-eval). Runs the frozen eval across user-chosen agents on fresh headless sessions via a pluggable adapter, grades quality/cost/perf, keeps the pareto-best variant, and versions every iteration with qvr. Use when a skill is already instrumented and you want a reproducible, article-grade before/after. (To BUILD the eval first, use create-skill-eval.) Trigger phrases: "run the skill optimization loop", "optimize <skill> across agents", "grade and evolve <skill> across versions".

trace-skill-activity

astra-sh/qvr

Records and queries what agents actually did, attributed to the skill that was active, using qvr's experimental audit subsystem. Use when a user wants observability into agent or skill behavior — e.g. "track what my skills are doing", "audit agent tool calls", "which skill ran during this session", "show recent agent activity", or "export agent traces for analysis". Covers qvr audit enable, discover, status, logs, sessions, and export. Experimental and opt-in; the command surface and storage may change.

fork-and-publish-skill

astra-sh/qvr

Customizes an installed agent skill and ships it back upstream or as a versioned fork using qvr's edit/publish authoring loop. Use when a user wants to modify, customize, fork, release, or publish a qvr skill — e.g. "edit this skill", "publish my changes", "fork a skill to my own repo", "cut a v1.0.0 release of a skill", or "iterate on a skill and tag new versions". Covers qvr edit, diff, status, and publish (--fork --migrate --tag, --auto-commit, root vs nested layout), including the consume-mode round trip.

onboard-skills

astra-sh/qvr

Discovers and installs agent skills into a project (or the user-global lane) with the qvr CLI, where qvr.toml declares intent and qvr.lock is the resolved source of truth for what loads. Use when a user wants to find, add, register, or install skills from a skills registry or GitHub repo with qvr — e.g. "register a skill registry", "search for a qvr skill", "qvr add this skill", "install a skill globally", or "why is my skill not loading after I dropped it into the agent's skills directory". Covers registry add, search, the one-step add github.com/org/repo/skill form, --global, and sync.

reproduce-skill-env

astra-sh/qvr

Reproduces an exact agent-skill set across machines, teammates, and CI using qvr's portable manifest and lockfile guarantees. Use when a user wants to share, pin, replicate, or CI-gate their qvr skills — e.g. "export my skills", "import this skill manifest", "pin everything to exact commits", "make skills reproducible", "fail CI if skills drift", or "onboard a teammate to the same skills". Covers qvr export/import, --frozen pinning, and the sync --locked / sync --check CI assertions.
