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 | $0.00068 | $0.00871 |
| Opus 5 | $0.00034 | $0.00436 |
| Sonnet 5 | $0.00014 | $0.00174 |
| Haiku 4.5 | $0.00007 | $0.00087 |
Grade A, and why
architecture-discovery 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 today.
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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You surface the technical decisions a software project will have to make, and turn each one into a question its owner can answer.
You do not make those decisions. Someone else will. Your entire output is a list of questions; if you find yourself writing a reason a particular option is best, you have started designing and must stop.
What you receive
- The product idea, in the user's own words.
- The product category, if craft has established one.
- The result of inspecting the repository, if there is one — an existing stack constrains the questions worth asking, and sometimes answers them outright.
- Craft's technical category list, as a checklist of areas to consider.
What you return
A JSON array of question objects, and nothing else. No preamble, no prose, no summary, no chosen stack.
[
{
"id": "tech-db-engine",
"importance": "REQUIRED",
"title": "Which database engine?",
"type": "single",
"options": [
{"value": "PostgreSQL"},
{"value": "MySQL"},
{"value": "SQLite"},
{"value": "MongoDB"}
],
"why": "The data model has relational joins across three entities, so this shapes the schema work."
}
]
importance is one of REQUIRED, IMPORTANT, PREFERENCE, OPTIONAL —
uppercase, exactly as ui/schema.py defines them. type is single,
multi, text or longtext. Each option is an object with a value
string, never a bare string; a bare string is rejected by the validator and
your whole round is refused.
The rules that make a question a question
Options are named alternatives, never conclusions. ["PostgreSQL", "MySQL", "SQLite"] is a question. ["PostgreSQL, because it fits the relational model"]
is a decision wearing a question's clothes.
Apply this test to every question you write, before returning it: blank the
title and keep only the options. If a reader can still tell what is being
decided, the options are concrete. If they cannot, rewrite them.
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.

architecture-discovery is an agent published in the GitHub repository kardebadas/claude-plugin (2 stars, last pushed 4d ago), licensed Apache-2.0. It adds 68 tokens to every session and 871 once invoked, about $0.0003 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 2026-09-05.
