What is t2000-machine-front-door?

A project guide for maintaining machine-readable discovery pages and agent-facing instructions. These pages help autonomous software find a marketplace’s APIs, skills, authentication rules, and other contracts.

Use it when changing API paths, marketplace or wallet commands, authentication, discovery URLs, signing rules, or the skills feed and validation files.

It keeps public discovery information in the correct source files and prevents documentation from drifting away from the actual machine interfaces.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00106	$0.00799
Opus 5	$0.00053	$0.00400
Sonnet 5	$0.00021	$0.00160
Haiku 4.5	$0.00011	$0.00080

Measured 9d ago against content hash 6e0d1c1045dd, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

t2000-machine-front-door scanned grade A with 1 finding 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Machine front door

https://t2000.ai/llms.txt is how autonomous agents learn the marketplace. It is a hand-authored short playbook, not generated docs.

One SSOT

The apex playbook lives at audric/apps/console/app/llms.txt/route.ts → serves t2000.ai/llms.txt. Never create a second machine-playbook SSOT — when the machine contract changes, edit that file.
docs.t2000.ai/llms.txt is Mintlify's doc index — a different job. Link it from More; do not merge the two.
The skills shelf enumerator is t2000-skills/feed.json (raw GitHub can't list a directory). t2000-skills/validate.ts fails CI when feed.json and skills/*/SKILL.md drift in either direction — edit both together.

The gate (when to update llms.txt)

Update ONLY when any of these change:

public api.t2000.ai/v1/* path / response contract agents rely on
CLI marketplace / wallet verbs agents are told to run
Connect auth model (Passport vs local key) or connector URL
discovery URLs (skills manifest, AGENTS.md, well-known)
who can sign (CLI keypair · SDK · prepare/submit · Connect Passport)
earn-first / fee / open-reject product locks agents must not misread

Skip for pure UI polish, copy nits, manage chrome, Connect card layout.

Facts that must stay true in the playbook

Connect ≠ BYO local key. Hosted MCP (mcp.t2000.ai/mcp) always signs as the Passport (Google/zkLogin) wallet — it does NOT accept an arbitrary local private key. Local Ed25519 keys belong to the CLI, @t2000/sdk (T2000.init / fromPrivateKey), and the sponsored prepare → sign → submit HTTP path.
Cite only live endpoints. Agent refs (#163 / numeric / @handle) resolve via MCP t2000_agents or the CLI — there is no public GET for them (/v1/agents/{numericId} is 404; only the full 0x… works).
No Connect dollar defaults in llms.txt — they drift; the SSOT is audric/packages/accounts/src/connect-defaults.ts.

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.

t2000-machine-front-door is a skill published in the GitHub repository mission69b/t2000 (23 stars, last pushed yesterday), licensed MIT. It adds 106 tokens to every session and 799 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls).
