Lands the guesswork case study drafted in #145, updated for everything that shipped since that draft was written (landing page live, v0.1.0 released, real demo assets).

  • data/projects/13-guesswork.mdx — status set to published (link now points at the live guesswork.findmalek.com instead of the bare repo, added a Landing Page section, updated Stack/Status to reflect what's actually shipped)
  • public/project/guesswork.png — the site's real Open Graph card, used as the case-study thumbnail
  • public/project/guesswork-demo.gif — the real terminal recording from the project's own README (unscripted model output, not staged)

Closes #145.

Summary by CodeRabbit

  • New Features
    • Added a published case-study page for Guesswork, an AI-powered zsh plugin that ranks command history entries and provides inline autosuggestions.
    • Documented its ranking workflow, interchangeable AI backends, technology stack, engineering challenges, project status, and interactive playground.

The case study is publishable only after its release status, implementation description, and media links accurately reflect the live project. These are bounded public-content defects, but should be corrected before publication.

Explanation

The description explains the main changes, lists the affected files, and references the linked issue. It does not follow the required template because it omits the Overview heading, the pre-merge checklist, and Additional Notes section.

Full details: Linked Issues check

Explanation

The new data/projects/13-guesswork.mdx documents the required problem, ranking pipeline, gating logic, provider architecture, stack, engineering challenges, status, links, metadata, route, tags, and published state for issue #145. The review cannot verify the required /project/guesswork.png asset because that path is excluded from review. The available summary also does not establish the required project-table entry or the asset and publication checks.

Serve the Guesswork media assets. Both deployed URLs return HTTP 404, so the project image and first-view demo are broken. Include the tracked files in the portfolio deployment or update both references to paths that resolve before publishing.

## 🧠 How It Works

1. **Candidates.** The last N distinct history entries are read from the zsh history file (extended-format parsing, multi-line commands supported). If any of them literally start with what you've typed, only those are sent for ranking ("prefix mode") — otherwise every recent entry is ("fuzzy mode").

Document project-script candidates and the single-prefix fast path.

The default CLI appends package.json scripts and Makefile targets to history candidates. A single literal prefix candidate returns immediately with score 1, without model ranking. Only multiple prefix candidates go through ranking.

## 📊 Status

`v0.1.0` released, four providers shipped, GitHub Actions CI green, a real install domain live over HTTPS, and the landing page from the proposal above now live with a working AI-backed playground. Distribution is in progress: listed in `unixorn/awesome-zsh-plugins`, submitted to a couple of other curated terminal/CLI lists, GitHub topics added, a Show HN post drafted but not yet posted. Still too early for install/usage numbers to mean anything — that's the next thing worth tracking once it's had real time in the wild.
