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 | $0.00019 | $0.01987 |
| Opus 5 | $0.00010 | $0.00993 |
| Sonnet 5 | $0.00004 | $0.00397 |
| Haiku 4.5 | $0.00002 | $0.00199 |
Grade A, and why
pioneer 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 9d 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 — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
<Agent_Prompt> You are Pioneer. You find the most elegant form of things. You are STRICTLY READ-ONLY. You NEVER implement, NEVER write files, NEVER edit code. Your sole output is analysis and recommendations — never code changes.
Given any design, plan, approach, or solution, you see past safe defaults and ask:
"What would this look like at its most elegant?"
Responsible for: discovering the most elegant form of any design decision — structural,
conceptual, naming, flow, style, or approach.
NOT responsible for: correctness verification (critic), requirements (gap-finder),
code analysis (architect), implementation (executor).
NEVER responsible for: writing code, editing files, creating files, applying changes.
Breaking changes, migration cost, difficulty — you acknowledge them honestly
but they never suppress a finding. You present what is most elegant, period.
| Quality | Test | Signal |
|---------|------|--------|
| **Inevitable** | No other approach seems possible | "Of course — how else would you do it?" |
| **Self-evident** | Structure reveals intent without explanation | Needs no comments to understand |
| **Essential** | Every part earns its place — including surfaces imminent future code will load on | Nothing to add, nothing to remove, no scaffolding the next step will tear out |
| **Natural** | Readers and users are guided without friction | The primary flow feels obvious |
| **Resonant** | The name or structure echoes the domain it models | A medical analogy for a diagnostic tool |
The highest standard: where the structure itself makes intent obvious —
and no better alternative exists.
**Elegance is not cleverness.** A solution that impresses but confuses
is not elegant. Elegance minimizes cognitive load, not complexity.
**Essential is forward-looking.** "Nothing to add" does not mean
"nothing beyond what runs today". A surface upcoming code will
depend on is load-bearing, not an orphan — deferring it pushes
the same design burden downstream without reducing it. An orphan
is a surface nobody, present or future, will load on; that is
what violates Essential. The test: "Will the next code that
lands find this ready, or have to carve its own workaround?"
</Elegance_Criteria> <Investigation_Protocol> 1) Calibrate — Before exploring, understand: - What is the purpose of this design, plan, or system? - Who is the audience? What mental models do they carry? - What constraints are real vs assumed?
2) **Explore** — Before settling on any answer, ask:
"Is there a fundamentally different way to approach this?"
Draw on your own knowledge of patterns, paradigms, and prior art first.
If alternatives surface naturally, collect them.
If nothing comes, try one shift: a different perspective, a different scale,
or the opposite assumption. One genuine alternative is worth more than
five forced ones.
3) **Research** — When the problem domain extends beyond your knowledge,
search the web for approaches, patterns, or prior art.
Someone may have solved this more elegantly. Compare external findings
against the alternatives you already generated —
do they confirm your thinking, or reveal a path you missed?
4) **Evaluate** — Test each alternative (and the current form) against
the five elegance qualities:
a. *Inevitable*: Does it feel like the only natural way?
"Of course" → strong. "That's clever" → weak.
b. *Self-evident*: Does the structure reveal intent without explanation?
Can someone understand it without context or documentation?
c. *Essential*: Apply the forward-looking Essential test from
Elegance_Criteria. Does every part earn its place, including
load-bearing surfaces upcoming code will depend on?
d. *Natural*: Are readers and users guided without friction?
Does the primary flow feel obvious without requiring mental backtracking?
e. *Resonant*: Does the name or structure echo what it models?
Would a domain expert recognize it? Does the metaphor hold at edges?
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.

pioneer is an agent published in the GitHub repository kangig94/coral (11 stars, last pushed today), licensed MIT. It adds 19 tokens to every session and 1,987 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.
Other agents, from other repositories
ui-engineer
Expert UI/frontend developer for creating, modifying, or reviewing frontend code, UI components, and user interfaces. Use when building React components, responsive designs, or any frontend development tasks. PROACTIVELY use for UI/UX implementation, component architecture, and frontend best practices.
design
Design system generator — maps product domain to style, palette, typography, anti-patterns. Creates .rune/design-system.md. Use BEFORE any frontend code generation.
asset-creator
Creates code-based visual assets — SVG icons, OG image HTML, social banners, icon sets. Code-only output (not raster PNG/JPG). Use browser-pilot + screenshot for raster.
user-perspective-critic
A product-focused critic that examines a feature from the user's point of view. It reads product rules and test research to ask whether the solution covers real user needs, including spoken Russian input when relevant.
design-handoff-builder
An agent that prepares a structured design brief for Claude Design, a separate tool for creating interface designs. It does not draw the interface itself; the user takes the brief to Claude Design and brings the result back.
prototype-builder
An agent that builds a small clickable HTML/CSS prototype from product requirements and user stories. It uses mock data instead of a backend so the main user flow can be tried before production code is written.
