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 | $0.00025 | $0.01620 |
| Opus 5.5 | $0.00010 | $0.00648 |
| Sonnet 5.5 | $0.00005 | $0.00324 |
| Haiku 4.5 | $0.00003 | $0.00162 |
Grade A, and why
Zakira.Imprint.Sample - String Utilities Library 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.
How it starts
The opening of the file, as written. The whole thing — 210 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Zakira.Imprint.Sample - String Utilities
This skill teaches you how to use the Zakira.Imprint.Sample NuGet package, which provides string manipulation utilities via the StringExtensions and StringHelper classes.
Namespace
All types are in the Zakira.Imprint.Sample.WithCode namespace:
using Zakira.Imprint.Sample.WithCode;
StringExtensions (Extension Methods)
These are extension methods on string. After adding the using directive, call them directly on any string instance.
Slugify
Converts a string to a URL-friendly slug (lowercase, hyphens, no special chars).
"Hello World! This is C#".Slugify() // => "hello-world-this-is-c"
"Café Résumé".Slugify() // => "cafe-resume" (diacritics removed)
" Multiple Spaces ".Slugify() // => "multiple-spaces"
Truncate
Truncates to a maximum length with a configurable suffix.
"Hello World".Truncate(8) // => "Hello..."
"Hello World".Truncate(8, "~") // => "Hello W~"
"Hi".Truncate(10) // => "Hi" (no truncation needed)
Mask
Masks the middle portion of a string, keeping visible characters at start and end.
"1234567890".Mask(2, 2) // => "12******90"
"SensitiveData".Mask(3, 3) // => "Sen*******ata"
"1234567890".Mask(2, 2, '#') // => "12######90"
ToTitleCase
Converts to Title Case (first letter of each word capitalized).
"hello world example".ToTitleCase() // => "Hello World Example"
"ALL CAPS INPUT".ToTitleCase() // => "All Caps Input"
RemoveDiacritics
Strips accent marks from characters.
"café résumé".RemoveDiacritics() // => "cafe resume"
"naïve über".RemoveDiacritics() // => "naive uber"
ToCamelCase
Converts to camelCase from any word-separated format.
"hello world example".ToCamelCase() // => "helloWorldExample"
"some-kebab-case".ToCamelCase() // => "someKebabCase"
"SOME_SCREAMING_SNAKE".ToCamelCase() // => "someScreamingSnake"
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.

Zakira.Imprint.Sample - String Utilities Library is a skill published in the GitHub repository MoaidHathot/Zakira.Imprint (23 stars, last pushed 4mo ago), licensed MIT. It adds 25 tokens to every session and 1,620 once invoked, about $0.0001 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.
