# Haystack Changelog

Recent updates and improvements to Haystack.

## July 2026

### Jul 5 - Built for Coding Agents
- Agent setup skill at /skill.md — a coding agent can install and configure Haystack on a repo end-to-end
- llms.txt and markdown for agent fetches — Claude, ChatGPT, and Perplexity agents get real content instead of an app shell
- New use-case pages at /use-cases covering what teams use Haystack for
- CLI 0.15.14 — `haystack init` detects your dev server and names configs after the repo
- `haystack-cli` and `haystack-review` on npm now resolve to the real CLI

## June 2026

### Jun 28 - Sharper Analysis, Bigger PRs
- Blast-radius verdicts grounded in named callers and callsites
- Materiality filter drops nitpick findings before they reach you
- Huge PRs with generated files no longer stall analysis; 4× analysis capacity
- New home page built around risk-based QA: one risky change, caught, tested, escalated

### Jun 22 - GitHub Access, Hardened
- Every GitHub read and write runs on GitHub App installation tokens — OAuth fallbacks removed
- Private-repo analysis results authorized by signed grants instead of live GitHub calls

## May 2026

### May 31 - The CLI Becomes a Platform
- `haystack setup --repo owner/name --yes` runs fully non-interactive; `--json` speaks NDJSON for coding agents

- Webhooks, headless tokens, and versioned JSON schemas for every `--json` output

### May 20 - Onboarding That Survives Real Repos
- Protected default branch? Setup opens a bootstrap PR through the Git Data API — works with rulesets and CODEOWNERS
- Repo scans clone and search your code directly, replacing the GitHub Search API
- Extracted rules arrive in plain language with per-card toggles
- Existing open PRs are backfilled for analysis when your config PR merges

### May 18 - Review Chat, Persistent and Polished
