Brand Scorer: cwd undefined — All Brand Scoring Calls Crash

Status: Fixed Severity: High — brand voice scores never stored; every social post and landing page silently skips scoring File: packages/agents/src/lib/brand-scorer.ts Observed: 2026-05-06 00:36 onwards (all social post and landing page completions)

Symptom


ERROR [brand-scorer] Brand scoring failed with exception
  TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string
  or an instance of Buffer or URL. Received undefined
    at mkdir (node:internal/fs/promises:855:10)
    at execute (packages/adapters/claude-local/src/server/execute.ts:72:11)
    at scoreBrandVoice (packages/agents/src/lib/brand-scorer.ts:65:26)
    at async Worker.processLandingPageWriterJob (landing-page-writer.worker.ts:405:24)

Fires on every social post, landing page, and blog post completion. Brand scores are never stored in the DB — brandScore, brandIssues, brandScoredAt always null.

Root Cause

scoreBrandVoice() calls the Claude adapter without a cwd in the config:


// BROKEN
const result = await adapter({
  config: {
    model: "claude-haiku-4",          // wrong model ID
    dangerouslySkipPermissions: true,
    timeoutSec: 30,
    // cwd: MISSING
  },
  ...
});

execute.ts:72 calls mkdir(config.cwd, { recursive: true }) unconditionally. config.cwd is undefined -> mkdir(undefined) throws ERR_INVALID_ARG_TYPE.

Secondary issue: model: "claude-haiku-4" is not a valid model ID. The correct ID is "claude-haiku-4-5-20251001".

Fix Applied

packages/agents/src/lib/brand-scorer.ts:


// Added imports
import path from "path";
import os from "os";
 
// Added cwd variable before the try block
const cwd = path.join(os.tmpdir(), "leadmetrics-agents", tenantId, "brand-scorer");
 
// Updated adapter config
config: {
  cwd,
  model:                      "claude-haiku-4-5-20251001",
  dangerouslySkipPermissions: true,
  allowedTools:               [],
  maxTurnsPerRun:             1,
  timeoutSec:                 60,
},

Requires agents server restart to take effect.
