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 | $0.02074 | $0.02074 |
| Opus 5 | $0.01037 | $0.01037 |
| Sonnet 5 | $0.00415 | $0.00415 |
| Haiku 4.5 | $0.00207 | $0.00207 |
Grade A, and why
hubspot-claude CLAUDE.md 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 10d 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.
This is a copy
95% identical to hubspot-claude AGENTS.md — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What This Is
A Claude Code plugin (/hubspot, package hubspot-agent, currently 0.2.14) for natural-language HubSpot CRM administration. Claude orchestrates ~44 specialist sub-agents that each call the hubspot CLI over Bash, with mandatory human-in-the-loop approval for every write. Implementation is complete and actively maintained — this is no longer a greenfield project.
Commands
pip install -e ".[dev]" # editable install with test deps
pytest -x # full suite (~960+ passed, 3 skipped)
pytest tests/test_cli_hitl.py -v # one module
pytest tests/test_safety.py::test_name # one test
claude plugin validate ./ # schema-check plugin.json + marketplace.json + hooks
bash scripts/check-artifact-allowlist.sh # shipping-artifact allowlist gate (run before release)
claude --plugin-dir ./ # load the plugin locally for a session
Tests use pytest-asyncio, respx/pytest-httpx (no live HubSpot calls), and hypothesis (tests/property_based/). tests/conftest.py isolates Path.home() so tests never touch real ~/.claude/hubspot/ state.
Architecture
Claude is the orchestrator; the CLI is the source of truth. There is no custom orchestration framework — Claude Code's native Agent tool spawns stateless sub-agents whose prompts come from hubspot agent-prompt <name>. Sub-agents call ${CLAUDE_PLUGIN_ROOT}/bin/hubspot tool <name> --input '<json>' --portal <id> --working-dir <dir>. --portal/--working-dir are top-level flags and must precede --input.
Three call paths, one handler set. bin/hubspot (POSIX sh venv resolver) → router.py, which prefers the warm-client daemon (daemon.py, Unix-socket JSON-RPC reusing one HubSpotClient + schema cache), falls back to in-process execution, and cli.py also runs sync. All three share handlers.py, so the approve→execute safety contract (destructive-count gate, undo snapshot, created-id capture, audit entry, clear-pending) is identical everywhere. When changing write behavior, change handlers.py/safety.py — never one path.
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.
