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 | $0.00045 | $0.01595 |
| Opus 5 | $0.00023 | $0.00797 |
| Sonnet 5 | $0.00009 | $0.00319 |
| Haiku 4.5 | $0.00005 | $0.00160 |
Grade A, and why
ia-design-iterator 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.
How it starts
The opening of the file, as written. The whole thing — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Core Methodology
For each iteration cycle, you must:
- Take Screenshot: Capture ONLY the target element/area using focused screenshots (see below)
- Analyze: Identify 3-5 specific improvements that could enhance the design
- Implement: Make those targeted changes to the code
- Document: Record what was changed and why
- Repeat: Continue for the specified number of iterations
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.

ia-design-iterator is an agent published in the GitHub repository iliaal/whetstone (32 stars, last pushed 6d ago), licensed MIT. It adds 45 tokens to every session and 1,595 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.
Other agents, from other repositories
context-analyzer
Analyzes context usage patterns, identifies waste, and provides optimization recommendations. Use when the user asks about token usage, context efficiency, or wants to optimize their Claude Code workflow.
reviewer-opus
Deeply reviews code for bugs, logic errors, and security vulnerabilities using comprehensive reasoning to catch subtle, high-impact issues that require careful analysis.
code-explorer
Read-only codebase explorer — searches, maps, and explains code structure. Use when a skill needs to delegate codebase exploration without risk of modification.
due-diligence
Use this agent for due diligence analysis, target screening, risk assessment, and systematic evaluation of companies or opportunities. Invoke when the task requires structured investigation against a DD framework. Examples: "screen Target X for acquisition red flags", "run commercial DD on Acme Corp", "does the…
financial-modeler
Use this agent for building financial models, business cases, ROI/NPV analysis, sensitivity analysis, benchmarking, and any quantitative analysis that requires structured modeling. Invoke when the task requires building or validating a financial model. Examples: "build an NPV model for the Acme acquisition", "run…
deal-analyzer
Use this agent when the user asks to analyze a property deal, run the numbers on a rental, evaluate an investment opportunity, or build a pro forma for real estate. Trigger when the user provides property details and wants a comprehensive financial analysis with metrics and recommendations. Examples: "run the numbers…
