A curated collection of Claude skills. Includes parallel-blueprint (decompose builds into parallel-execution plans with frozen interface contracts and per-terminal prompts), test-craft (3-phase generate-critique-refine test authoring), and quiver-upgrade (in-session update notifications and pull tooling).
Decompose an idea or build prompt into a parallel-execution plan and emit two artifacts — (1) a comprehensive PDF blueprint and (2) a folder of ready-to-paste prompts (one per workstream plus an integrator) for separate Claude Code terminals. The methodology centers on frozen interface contracts (data schemas, function signatures, event shapes, API endpoints) negotiated up front so each owner works asynchronously against mocked contracts in a directory they alone own. Use when the user says "plan this for parallel execution", "split into agents", "decompose into workstreams", "hackathon plan", "build plan with multiple Claude Code terminals", "parallelize this across N Claudes", or otherwise asks to fan a build out across multiple Claude sessions. Do NOT use for single-threaded coding tasks, simple scripts, single-file edits, debugging sessions, code review, refactors, or anything that fits comfortably in one terminal.
Update the local Quiver clone (the source-of-truth for all Quiver skills) to the latest version. Detects the clone path, fetches origin/main, shows the changelog of new commits, and pulls if the user confirms. Skills installed via symlink pick up the new version immediately. Use when asked to "upgrade quiver", "update quiver", "pull quiver", "get the latest quiver skills", "are there new quiver updates", or whenever the SessionStart hook prints a "Quiver: N updates available" notice.
Author comprehensive, behavior-focused tests via a 3-phase generate → critique → refine loop. Phase 1 produces a first-cut test suite covering happy paths, edge cases, error paths, and boundary conditions in the project's existing test framework. Phase 2 spawns an adversarial critique subagent that reviews the suite for missing cases, implementation-detail testing, hidden-failure mocks, redundancy, and determinism issues. Phase 3 applies the critique and runs the suite. Use when the user says "write tests", "add tests", "test this code", "comprehensive tests", "generate tests with critique", "test-craft this", "I need tests for X", or otherwise asks for high-quality test coverage on a specific file, module, or feature. Do NOT use for one-off assertions, ad-hoc debugging tests, simple smoke checks, or when the user says "just write a quick test" — those should be done inline without ceremony.

A curated collection of Claude skills — modular capability units that Claude Code (and other Claude harnesses) loads on demand when their trigger conditions match what you're working on.
Each skill lives in its own folder under skills/ with a SKILL.md that has YAML frontmatter (name, description) plus any supporting templates and scripts. The format follows Anthropic's standard skill convention.
Three options, easiest first.
The repo ships its own one-plugin marketplace at .claude-plugin/marketplace.json, so you can add it as a marketplace and install the bundled plugin in two commands:
/plugin marketplace add asrinivasan75/Quiver
/plugin install quiver@quiver-plugins
That's it. Claude Code installs the plugin under ~/.claude/plugins/, registers all three skills automatically, and adds an entry to enabledPlugins in ~/.claude/settings.json. The bundled hooks/hooks.json wires the SessionStart update-check hook for you. Open a new Claude Code session and the skills are available.
To upgrade to a newer Quiver release, run /plugin upgrade quiver@quiver-plugins (or use /quiver-upgrade from inside a session — it works for plugin installs too, but the plugin path uses Claude Code's update mechanism).
This keeps a single working copy of the repo and lets you git pull to get updates. Symlinks mean the live skill files are always whatever Quiver has on disk — useful if you're contributing skills or want bleeding-edge changes.
git clone https://github.com/asrinivasan75/Quiver.git ~/src/Quiver
mkdir -p ~/.claude/skills
ln -s ~/src/Quiver/skills/parallel-blueprint ~/.claude/skills/parallel-blueprint
ln -s ~/src/Quiver/skills/test-craft ~/.claude/skills/test-craft
ln -s ~/src/Quiver/skills/quiver-upgrade ~/.claude/skills/quiver-upgrade
To install into a single project instead of globally, replace ~/.claude/skills/ with <your-project>/.claude/skills/. Claude Code reads both paths.
If you go this route, wire the SessionStart update notice manually by adding to ~/.claude/settings.json:
{
"hooks": {
"SessionStart": [
{
"hooks": [
{
"type": "command",
"command": "$HOME/.claude/skills/quiver-upgrade/scripts/check-updates.sh"
}
]
}
]
}
}
If you only want one skill and don't want it to update at all:
git clone https://github.com/asrinivasan75/Quiver.git /tmp/Quiver
cp -R /tmp/Quiver/skills/parallel-blueprint ~/.claude/skills/
rm -rf /tmp/Quiver
Open a new Claude Code session and run /context. The skills should appear in the Skills list. Or just describe a task that matches a skill's trigger description — Claude will surface it automatically.
If you switch from Option 2/3 to Option 1, remove the symlinks/copies first to avoid duplicate skill registrations:
rm ~/.claude/skills/parallel-blueprint ~/.claude/skills/test-craft ~/.claude/skills/quiver-upgrade
# also remove the manual SessionStart hook entry from ~/.claude/settings.json if you added one
| Skill | What it does |
|---|---|
parallel-blueprint | Decomposes an idea or build prompt into a parallel-execution plan with frozen interface contracts, then produces a comprehensive PDF blueprint and a folder of per-terminal prompts (one per workstream + an integrator) ready to paste into separate Claude Code instances. |
test-craft | Authors comprehensive, behavior-focused tests via a 3-phase generate → critique → refine loop. Phase 2 spawns an adversarial subagent that reviews the suite for missing cases, implementation-detail testing, hidden-failure mocks, and determinism issues; phase 3 applies the critique. |
quiver-upgrade | Updates the local Quiver clone (git fetch + ff-only git pull) and reports which skills will pick up changes via symlink vs. need a manual re-copy. Pairs with a SessionStart hook (auto-wired by the plugin install path, manual under Option 2) that prints 🏹 Quiver: N updates available in-session when new commits land on origin/main. The hot path is local-only; a background git fetch runs on a 4-hour cadence so the session is never blocked by network I/O. |
