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.

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 | $0.00012 | $0.00806 |
| Opus 5 | $0.00006 | $0.00403 |
| Sonnet 5 | $0.00002 | $0.00161 |
| Haiku 4.5 | $0.00001 | $0.00081 |
Grade A, and why
hello 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Negotiates the protocol version and optionally authenticates the connection.
Syntax
HELLO protover [AUTH username password] [SETNAME clientname]
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
protover |
integer | Yes | Protocol version to use (2 for RESP2, 3 for RESP3) |
AUTH username password |
string, string | No | Optional inline authentication |
SETNAME clientname |
string | No | Optional client connection name |
Return Value
Returns connection metadata in a format determined by the negotiated protocol version:
- RESP2: Array of alternating key-value pairs.
- RESP3: Map.
| Field | Type | Description |
|---|---|---|
server |
string | Server product name (Kronotop) |
version |
string | Server version |
proto |
integer | Negotiated protocol version |
id |
integer | Client connection ID |
mode |
string | Server mode (cluster) |
role |
string | Server role (master) |
modules |
array | Loaded modules (empty array) |
Behavior
Sets the RESP protocol version for the current session. If AUTH is provided, authenticates the connection using the
same logic as the AUTH command. If SETNAME is provided, sets the client connection name.
The protocol version is applied after the response is generated, so the response itself is encoded using the newly negotiated version.
This command does not require the cluster to be initialized.
Errors
| Error | Condition |
|---|---|
NOPROTO |
Unsupported protocol version (not 2 or 3) |
WRONGPASS |
Invalid username or password in the AUTH clause |
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.

hello is a command published in the GitHub repository kronotop/kronotop (307 stars, last pushed today), licensed Apache-2.0. It adds 12 tokens to every session and 806 once invoked, about $0.0001 per session on Opus 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.
