carta-round-history

carta-round-history is a skill for Claude Code from carta/plugins. It costs 51 tokens per session (1,969 once invoked), scanned A, original, Apache-2.0.

A company's financing history: the investment rounds it has completed, when they happened, which share class was issued, the price per share, how much cash was raised, and who invested.

In plain words
What is it for?
Use it to answer questions about past seed or later rounds, total capital raised, round prices, participating investors, and the largest investments.
Why use it?
It gathers funding information into a round-by-round view instead of requiring you to inspect individual records. You can choose a quick summary or detailed investor information.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

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.

Security

Grade A, and why

carta-round-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 4d 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 — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Round History

Fetch financing history and summarize by round, or use the cap table by share class for a quick overview.

When to Use

  • "Show me the funding history"
  • "What rounds has this company raised?"
  • "How much capital was raised in the Series A?"
  • "List all financing rounds"
  • "Who invested in each round?"
  • "What was the price per share for the seed?"

Prerequisites

You need the corporation_id. Get it from list_accounts if you don't have it.

Data Retrieval

Detail mode: This command supports detail=summary (round count, total cash raised, by-round breakdown — fast) and detail=full (individual security records with per-investor data, issue dates, price per share). Choose the right mode upfront based on user intent — see Workflow.

Ordering: Pass ordering to sort server-side — e.g. -cash_paid for largest investments first. Fields: issue_date, quantity, stakeholder_name, cash_paid, prefix_number. Combine with detail=full for "top N investors" queries; otherwise the default (chronological) order is fine.

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.
