Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.01279 |
| Opus 5.5 | $0.00011 | $0.00512 |
| Sonnet 5.5 | $0.00005 | $0.00256 |
| Haiku 4.5 | $0.00003 | $0.00128 |
Grade A, and why
communication-history scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Read bulk-operations/SKILL.md first — JSONL piping, batch read, and jq reshape patterns (resources/json-patterns.md) apply. hubspot activities list --help is the source of truth.
Output shape
activities list returns one flat row per activity, sorted newest-first: {id, type, timestamp, lastModified, title, body, status, owner_id}. timestamp and lastModified are ISO 8601; type is CALL|EMAIL|NOTE|MEETING|TASK. Different from the raw hs_call_* / hs_timestamp (Unix ms) on the underlying objects — fetch those with hubspot objects get --type calls if needed.
For point-in-time filtering compare lastModified (hs_lastmodifieddate, when the body was last edited), not timestamp (engagement creation time) — otherwise you include content edited after your cutoff.
All activity for a record
Pass exactly one of --contact, --deal, --company, --ticket (or --type <object_type> --record <id> for any other object type). Use --activity-type CALL|EMAIL|NOTE|MEETING|TASK to filter by activity kind, --limit N for the most recent N. Note --type is now the object-type flag, not the activity-kind filter:
hubspot activities list --contact 73235
hubspot activities list --deal 67890 --activity-type CALL
hubspot activities list --type subscriptions --record 45123 --activity-type NOTE
hubspot activities list --contact 73235 --limit 10
Client-side date filter
ISO 8601 strings compare lexicographically.
CUTOFF=$(date -v-30d +%Y-%m-%dT%H:%M:%SZ) # macOS
# CUTOFF=$(date -u -d '30 days ago' +%Y-%m-%dT%H:%M:%SZ) # Linux
hubspot activities list --contact 73235 \
| jq -c --arg cutoff "$CUTOFF" 'select(.timestamp > $cutoff)'
Compact timeline
hubspot activities list --contact 73235 --limit 20 \
| jq -r '"\(.timestamp[0:10]) \(.type) \(.title)"'
Pre-call brief
Four piped commands: contact + company + open deals + activity. Use batch objects get over stdin — never xargs -I{} (see bulk-operations/SKILL.md).
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

communication-history is a skill published in the GitHub repository HubSpot/agent-cli-skills (28 stars, last pushed 9d ago), licensed Apache-2.0. It adds 27 tokens to every session and 1,279 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
