If you've ever inherited a HubSpot CRM with duplicate contacts, half-empty fields, and "Acme Inc" spelled six different ways, this is your cleanup toolkit. It wraps the HubSpot CLI to find incomplete records with property filters, normalize values in bulk through JSONL pipes, and merge duplicates with the native merge API. The deduplication logic is straightforward but requires pagination to catch duplicates that span API pages, which the docs walk through clearly. Everything routes through a dry run, digest, and confirm flow borrowed from the bulk-operations skill, so you won't accidentally merge 500 contact pairs without a preview. Merges are irreversible, but the history command gives you an audit trail.
npx -y skills add hubspot/agent-cli-skills --skill crm-data-quality --agent claude-codeInstalls into .claude/skills of the current project.
Read bulk-operations/SKILL.md first — JSONL piping, batch read, pagination, and dry-run/digest/confirm gating apply to every command below.
Don't guess property names. List them:
hubspot properties list --type contacts --format table
hubspot properties list --type contacts | jq -c 'select(.type=="enumeration") | {name, label}'
Same for --type companies, deals, or any custom type (hubspot objects types).
!name = NOT_HAS_PROPERTY (missing or empty). Bare name = HAS_PROPERTY. Within one --filter, chain with AND; multiple --filter flags are OR'd.
hubspot objects search --type contacts --filter "!email" --properties firstname,lastname,company
hubspot objects search --type contacts --filter "!phone AND !mobilephone" --properties email
hubspot objects search --type contacts --filter "!hubspot_owner_id" --properties email,lifecyclestage
For >100 results, use the pagination loop from bulk-operations.
Search → reshape with jq → pipe into update. objects update is irreversible, so --dry-run first — the dry-run → digest → confirm flow is required at every row count, not just >100 (bulk-operations covers it end to end). Reshape patterns: bulk-operations/resources/json-patterns.md.
# Collapse spellings into one canonical value — 1. preview
hubspot objects search --type contacts --filter "company~acme" \
| jq -c '{id, properties:{company:"Acme Corporation"}}' \
| hubspot objects update --type contacts --dry-run \
| tee /tmp/normalize.preview.jsonl
# 2. lift the digest + confirm (present at every row count)
digest=$(jq -r 'select(.digest != null) | .digest' /tmp/normalize.preview.jsonl)
confirm=$(jq -r 'select(.digest != null) | .target.id' /tmp/normalize.preview.jsonl) # single: record ID; batch of 2+: row count
# 3. execute — re-pipe the SAME inputs plus --digest/--confirm
hubspot objects search --type contacts --filter "company~acme" \
| jq -c '{id, properties:{company:"Acme Corporation"}}' \
| hubspot objects update --type contacts --digest "$digest" --confirm "$confirm"
# Lowercase emails (read, reshape, write) — 1. preview
hubspot objects search --type contacts --filter "email" --properties email \
| jq -c '{id, properties:{email: (.properties.email | ascii_downcase)}}' \
| hubspot objects update --type contacts --dry-run \
| tee /tmp/lower.preview.jsonl
# 2. lift the digest + confirm, then 3. re-pipe the SAME inputs to execute
digest=$(jq -r 'select(.digest != null) | .digest' /tmp/lower.preview.jsonl)
confirm=$(jq -r 'select(.digest != null) | .target.id' /tmp/lower.preview.jsonl)
hubspot objects search --type contacts --filter "email" --properties email \
| jq -c '{id, properties:{email: (.properties.email | ascii_downcase)}}' \
| hubspot objects update --type contacts --digest "$digest" --confirm "$confirm"
hubspot objects mergeSecondary is folded into primary and deleted. Irreversible. Dry-run/digest/confirm gating applies.
# Single pair — dry-run first, then execute with the digest + confirm (confirm = the secondary ID for one pair)
hubspot objects merge --type contacts --primary 149 --secondary 425 --dry-run
hubspot objects merge --type contacts --primary 149 --secondary 425 --digest <hash> --confirm 425
Bulk: pipe JSONL {"primary":"...","secondary":"..."} on stdin (omit --primary/--secondary).
Pagination required. objects search caps at 100 rows per call and jq -s slurps a single stream into memory — running the snippet below against a raw search will silently miss every duplicate that crosses a page boundary. Collect the full set first with the pagination loop from bulk-operations/SKILL.md (write to /tmp/contacts.jsonl), then dedupe from the file:
# /tmp/contacts.jsonl produced by the pagination loop (bulk-operations/SKILL.md)
jq -s -c '
group_by(.properties.email)[]
| select(length > 1)
| sort_by(.id | tonumber)
| .[0].id as $p | .[1:][] | {primary: $p, secondary: .id}
' /tmp/contacts.jsonl \
| hubspot objects merge --type contacts --dry-run | tee /tmp/merge-preview.jsonl
Lift the digest/confirm from the preview line at any size — select(.digest != null); for a batch the confirm is the pair count (.target.id), and mutation_kind is BulkData only above the 100-row threshold (RecordMutation at or below it, but the digest is present either way). Re-pipe the same producer with --digest/--confirm (see bulk-operations).
hubspot properties list (and get, batch-read) emits {name, label, type, fieldType, groupName, optionsDisplay} per row. Enum option values are exposed via properties options-list — no need to read them off a live record or the UI.
# Count properties per group (HubSpot groups standard fields; custom groups stand out)
hubspot properties list --type contacts | jq -rs 'group_by(.groupName) | map({group: .[0].groupName, count: length}) | .[]'
# All enumeration properties
hubspot properties list --type contacts | jq -c 'select(.type=="enumeration") | {name, label, fieldType}'
# Create a DQ flag property, then set it via the normalize pattern in section 2
hubspot properties create --type contacts --name dq_missing_phone --label "DQ: Missing Phone" --prop-type string --field-type text
properties options-*, v0.11.0)# List the allowed options on an enumeration property
hubspot properties options-list --type contacts hs_buying_role
# each row: {"value":"EVALUATOR","label":"Evaluator","displayOrder":9,"hidden":false}
# Add / rename / remove an option (options-delete is irreversible — dry-run → digest → confirm, confirm = the option value)
hubspot properties options-create --type contacts hs_buying_role --label "Evaluator" --value EVALUATOR --display-order 9
hubspot properties options-update --type contacts hs_buying_role --value EVALUATOR --label "New Label"
hubspot properties options-delete --type contacts hs_buying_role --value EVALUATOR --dry-run
hubspot properties options-delete --type contacts hs_buying_role --value EVALUATOR --digest <hash> --confirm EVALUATOR
HubSpot-defined properties with read-only options reject options-create/update/delete before the API is called.
Merge is irreversible. After any merge, hubspot history --since 1h captures the audit trail. If wrong direction, restore the secondary from the UI's recycle bin.
