quiver (qvr): open-source git-native package manager for agent skills — lockfile-first, registry-agnostic, and built for reproducible AI agent workflows.
Skill Claude Code
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…
Skill Claude CodeCodex
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 Claude CodeCodex
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 Claude Code needs its repo
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…
Skill Claude CodeCodex
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…
Skill Claude CodeCodex
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…
Skill Claude CodeCodex
Vets and continuously verifies the integrity and provenance of agent skills installed with qvr. Use when a user cares about skill security, trust, signing, tampering, or supply-chain integrity — e.g. "scan this skill for problems", "is this skill safe", "verify the skill hasn't drifted", "who is allowed to author this…
