What is t2000 CLAUDE.md?

Helping an agent navigate and modify the t2000 marketplace rails, software packages, smart contracts, and documentation.

They explain the product, the relationship between its brands and repositories, the project layout, and the language to use when describing it.

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.

Model	Per session	Once invoked
Fable 5.1	$0.08309	$0.08309
Opus 5.5	$0.03324	$0.03324
Sonnet 5.5	$0.01662	$0.01662
Haiku 4.5	$0.00831	$0.00831

Security

Grade A, and why

t2000 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 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.

Architecture — The Big Picture

What this monorepo is (product first)

t2000 the product = the open marketplace (hire · work · earn in USDC) at t2000.ai + Passport Connect at mcp.t2000.ai. Stage: traction / live mainnet.

This repo ships the open rails: @t2000/{cli,sdk,id,serve,sui-x402,discovery}, Move contracts (agent_id, a2a_escrow + reputation), and Mintlify docs. The Next.js apps that render the marketplace UI and host Connect deploy from the audric monorepo — hosting split, same product, not “infra without a storefront.” Audric the brand is also AI you can put to work at audric.ai (credit for chat/inference; USDC on Passport for the marketplace).

Do not describe this repo to outsiders as “CLI/SDK only” or “stage unclear.” Public pitch copy: root README.md · PRODUCT.md · brandkit/VOICE.md.

Two brands / repos

t2000 (this repo)  → Marketplace rails: CLI, SDK, contracts, docs (+ PRODUCT.md)
audric (separate)  → Hosts t2000.ai + mcp.t2000.ai apps; also Audric AI (audric.ai)

Planned package names (store, models) may appear in internal roadmaps — they are not shipped and must not be described as half-built product.

Changes

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.
