Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@pickled-dev/cli

v0.38.0

Published

Test what agents actually understand about your product

Readme

@pickled-dev/cli

Pickled tests whether real agents can answer and build with your product, across declared context paths, using deterministic evidence.

The CLI for Pickled. Use it locally or in CI to check whether agents can answer and build from the product context you publish. No LLM grades another LLM.

Full docs: docs.pickled.dev.

Install

bun add -g @pickled-dev/cli
# or run without installing:
bunx @pickled-dev/cli <command>

Commands

  • pickled init [path] writes a starter pickled.yml.
  • pickled test [path] scores a question's examples.pass / examples.fail offline. No model calls.
  • pickled check [path] runs the questions: asks the agents and scores their answers against the fact contract.
  • pickled build [path] has edit-capable agents work in a fresh workspace and scores the verifier.
  • pickled ci [path] runs the configured questions and builds in one pass, writes a receipt per kind, and gates the run. For CI.
  • pickled audit [path] scans agent-facing files for broken refs and oversized sections. No model calls.
  • pickled report <file> re-renders a saved receipt as terminal, markdown, or JSON. No model calls.

Minimum config

A registered source is the context Pickled is allowed to use: a local file or a URL. Anything not registered does not count.

schemaVersion: 2

product:
  name: my-product
  description: short one-liner about what your product does

sources:
  readme: { path: ./README.md }

agents:
  quick:
    provider: claude-code
    model: claude-haiku-4-5

contexts:
  from_readme: { mode: inject, source: readme }

facts:
  install_command:
    statement: my-product installs with bunx my-product.
    match:
      allOf: ["bunx my-product"]

questions:
  - id: install
    question: How do I install my-product?
    agents: [quick]
    contexts: [from_readme]
    expects: [install_command]

thresholds:
  questions: 80

That runs one question with your README injected. Add more contexts to compare model memory, injected sources, web discovery, and MCP discovery. A build instead has the agent edit a workspace and runs your verifier; run it with pickled build.

Cost controls

For paid agents, a run can expand to many (agent × context) cells. These flags keep that in check:

pickled check . --plan                           # dry run: no model calls
pickled check . --max-cells 10                   # fail before spending
pickled check . --sample 2 --seed nightly-2026   # deterministic sample per task
pickled build . --plan                           # preview build cells and executions
pickled build . --verify-only                    # prove the harness; no agent runs

pickled build --verify-only runs each build's preflight and reference control (the untouched fixture must fail failToPass and pass passToPass; a declared referenceSolution must apply and clear the verifier) and prints one line per build: proven, unproven (no reference declared), or broken. No agent runs, so it is the cheap way to check a fixture before spending tokens, and it exits non-zero if any harness is broken. --output file.json writes the per-build proof results as JSON (or --json to print them to stdout). It accepts only --task, --json, --output, and --verbose; the agent, sampling, and threshold flags are rejected rather than silently ignored.

The receipt records expandedCells, selectedCells, and seed so a reviewer can see what ran and rerun the same sample. Builds also report selectedExecutions (cells x trials), which is what --max-cells gates.

Narrow a run by the names in pickled.yml:

pickled check . --task install
pickled check . --agent quick
pickled check . --context from_readme

In CI

pickled ci runs the configured questions and builds in one pass, writes a CI-safe JSON receipt per kind, appends a markdown summary to the job summary, and exits non-zero if any thresholded run fails:

- run: |
    pickled ci . \
      --questions-max-cells 20 \
      --builds-max-cells 4 \
      --report-dir pickled-reports
- uses: actions/upload-artifact@v4
  if: always()
  with:
    name: pickled-reports
    path: pickled-reports/*.json

It appends markdown to $GITHUB_STEP_SUMMARY automatically when that variable is set (override with --summary-file). It runs both kinds to completion even if one fails its threshold, so the job always uploads every receipt. With no --questions/--builds flag it runs both kinds the config declares.

The receipts are CI-safe by default: verdicts, evidence ids, provenance, and build attempts, without full answers, source text, transcripts, diffs, or command output. To re-render a saved receipt later (for example a different format from an uploaded artifact) without rerunning paid agents, use pickled report <file> --format markdown|terminal|json; pass --verbose there for a forensic receipt.

Current support

| Concept | Works today | | --- | --- | | Sources | local files, URLs, codebase globs | | Context modes | memory, inject, web, mcp | | Agents | Claude Code, Codex CLI, Anthropic API, OpenAI API | | Output | terminal and JSON for runs; markdown from saved receipts and audits |
