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 5.1 | $0.00043 | $0.00565 |
| Opus 5 | $0.00022 | $0.00282 |
| Sonnet 5 | $0.00009 | $0.00113 |
| Haiku 4.5 | $0.00004 | $0.00056 |
Grade A, and why
build-inline-keyboard 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 5d 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.
What it actually says
Build Inline Keyboard
Quick Start
Use inlineKeyboardMarkup { } or inlineKeyboardMarkup(block) to create inline keyboards. Attach via markup() or inlineKeyboardMarkup { } on send actions.
message("Choose an option:")
.inlineKeyboardMarkup {
"Option A" callback "opt_a"
"Option B" callback "opt_b"
newLine()
"Open link" url "https://example.com"
}
.send(user, bot)
Button Types
| Type | Syntax | Use case |
|---|---|---|
| Callback | "Label" callback "data" or callbackData("Label") { "data" } |
Button press sends callback to bot (1-64 bytes) |
| URL | "Label" url "https://..." |
Opens URL when pressed |
| Web App | "Label" webAppInfo "https://..." |
Opens Web App |
| Switch inline | "Label" switchInlineQuery "query" |
Opens inline mode in another chat |
| Switch inline (current) | "Label" switchInlineQueryCurrentChat "query" |
Inserts bot + query in current chat |
| Pay | "Pay" pay() |
Payment button |
| Copy text | "Label" copyText "text" |
Copies text to clipboard |
Rows
- Each
url(),callbackData(), etc. adds a button to the current row - Use
newLine()orbr()to start a new row
inlineKeyboardMarkup {
"Yes" callback "yes"
"No" callback "no"
newLine()
"Cancel" callback "cancel"
}
Attaching to Messages
Actions with MarkupFeature (e.g. message, sendPhoto, editMessageText) support:
inlineKeyboardMarkup { ... }— builder blockmarkup(inlineKeyboardMarkup { ... })— explicit markup
Callback Data Limits
- 1-64 bytes for
callbackData - Use prefixes for routing:
"action:id","vote:123"
Reference
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.

build-inline-keyboard is a skill published in the GitHub repository vendelieu/telegram-bot (248 stars, last pushed 9d ago), licensed Apache-2.0. It adds 43 tokens to every session and 565 once invoked, about $0.0002 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.
