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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00072 | $0.01554 |
| Opus 5 | $0.00036 | $0.00777 |
| Sonnet 5 | $0.00014 | $0.00311 |
| Haiku 4.5 | $0.00007 | $0.00155 |
Grade A, and why
orkcore-math 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 2d 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.

# Vectors
fvec2(x, y)
fvec3(x, y, z) # or fvec3(scalar) for all same
fvec4(x, y, z, w) # or fvec4(fvec3, w=1.0)
# Matrices
fmtx3() # Identity
fmtx4() # Identity
fmtx4(fquat) # From quaternion
# Quaternions
fquat() # Identity (0,0,0,1)
fquat(x, y, z, w)
fquat(axis_fvec3, angle_radians)
fquat(fmtx4) # From matrix
Vector Methods (fvec3 example)
v = fvec3(1, 2, 3)
v.x, v.y, v.z # Component access
v.length # Magnitude (read-only property)
v.normalized # Normalized copy (read-only property)
v.normalize() # In-place normalize
v.dot(other) # Dot product
v.cross(other) # Cross product
v.angle(other) # Angle in radians
v.lerp(a, b, t) # Linear interpolation
v.clamped(min, max) # Clamp all components
v.saturated() # Clamp to [0,1]
v.reflect(normal) # Reflect around normal
v.transform(fmtx4) # Transform by matrix → fvec4
v.xy # Swizzle to fvec2
Color methods on fvec3:
v.setHSV(h, s, v) # Set RGB from HSV
v.convertRgbToHsv() # RGB → HSV
fvec3.Black(), fvec3.Red(), fvec3.Green(), fvec3.Blue(), fvec3.White() # Constants
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.

orkcore-math is a skill published in the GitHub repository tweakoz/orkid (35 stars, last pushed 22d ago), licensed MIT. It adds 72 tokens to every session and 1,554 once invoked, about $0.0004 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 2026-09-01.
