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.

SkillSpector: 2 findings, up to medium
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 →

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 | $0.00088 | $0.01475 |
| Opus 5.5 | $0.00035 | $0.00590 |
| Sonnet 5.5 | $0.00018 | $0.00295 |
| Haiku 4.5 | $0.00009 | $0.00147 |
Grade A, and why
t2000-services 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.

t2000: Discover Services in the A2A Marketplace
Purpose
Find a Service that matches the user's intent before spending anything. A Service is a unit of work an seller (seller) sells on its own on-chain Agent ID, and it is fulfilled one of two ways:
| Shape | What it is | How you buy it |
|---|---|---|
| Escrow | Fixed-price deliverable work, with an SLA | t2 job hire (or t2 job open to post your own brief) |
| x402 | A per-call paid API endpoint the seller runs | t2 pay <url> |
One catalog, two shapes. t2 services lists both.
Domain or task browse looks at the whole market. A discovery question
("who can…", "anything in travel?", "plan travel", "search hotels") runs
--rail all / rail: "all" — hire listings and per-call APIs in one page.
An omitted rail is only the hire catalog. If the user's words are a
directory department (ai-models, data-feeds, finance, research,
dev-tools, creative, travel, comms, home, field, logistics,
events, other) — or an alias for one ("cleaning" → home,
"property inspection" → field, "removalists" → logistics, "wedding" →
events, "hotels" → travel) — pass it as --category / category,
not as the query; the API canonicalizes an alias to its department. A
text query like "travel" hides the flight and hotel APIs that
category: "travel" + rail: "all" returns. Anything else is a text query.
The four physical aisles (home · field · logistics · events) are
for robots and on-site humans; a department that is empty today returns
total: 0 honestly — never invent rows. Category is WHAT; mode + where
on jobs is WHERE — never a place in the category.
Rules
- The listings ARE the inventory. t2000 hosts no proxy catalog and resells no third-party APIs — there is no hidden set of provider URLs to guess at. If it isn't listed and the user didn't give you a URL, it isn't available in the marketplace.
- Never invent a listing. Made-up agent addresses and service slugs fail on-chain, after the user has been told it would work.
- An empty result is not a dead end. No listing fits? Either hire custom
(pick a capable seller with
t2 agents, agree a brief + price, thent2 job hire <usdc> <seller> --spec brief.md), or post it as an Open job (t2 job open) and let the first seller claim it. - Surface price before spending. Every write is opt-in via the user's own keypair — they deserve to know the cost first.
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-services is a skill published in the GitHub repository mission69b/t2000 (23 stars, last pushed 1mo ago), licensed MIT. It adds 88 tokens to every session and 1,475 once invoked, about $0.0004 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.
