Structured Error Categorization

Every Pare tool now classifies failures into categories an agent can match on programmatically (#589):

{
  "error": true,
  "category": "permission-denied",
  "command": "git",
  "exitCode": 128,
  "message": "fatal: could not read Username"
}

Categories include: command-not-found, permission-denied, timeout, network-error, authentication-error, conflict, parse-error, invalid-input, not-found, and others. Agents can branch on these directly instead of pattern-matching stderr text.

---

Centralized Input Schemas

Common parameters like path, compact, fix, config, and filePatterns are now defined once in @paretools/shared and reused across all tools (#573). This ensures consistent behavior and makes it impossible for one server to accidentally define path differently from another.

---

createServer() Factory

New createServer() factory in @paretools/shared eliminates server boilerplate (#601). Adding a new MCP server is now 6 lines:

import { createServer } from "@paretools/shared";
import { registerTools } from "./tools/index.js";
await createServer({ name, version, instructions, registerTools });

---

Tiered CI Pipeline

CI now runs a light check suite (build, lint, format) on normal PRs, with the full test matrix (Linux/macOS/Windows x Node 20/22) reserved for version PRs and nightly runs (#569). This cuts PR feedback time significantly while maintaining full coverage on releases.

Other CI improvements:

• Canary pre-release publish workflow (#600)
• GitHub App token for release workflow (#595)
• OpenSSF Scorecard alerts resolved (#598)
• npm audit made advisory so outages don't block PRs (#590)

---

Bug Fixes

• Fix flag injection guards that incorrectly blocked legitimate values like git sort keys (-creatordate) and gitleaks logOpts (#565)
• Explicit error for invalid regex patterns in search tool (#563)
• Resolve minimatch ReDoS audit vulnerability (#564)
• Improve reliability of process cleanup test on Windows (#566)
• Adjust coverage thresholds for lerna/rollup tests (#597)

---

Testing

~5,500 tests across 218 test files, plus centralized coverage reporting via turbo pipeline (#562).
