Prompt Library¶

System prompts for coding agents, across architecture, data, platform, protocols, SDK, and financial engineering. 45 prompts: 29 cross-stack engineering practice, 16 covering multi-broker trading systems.

Each prompt is a standalone system prompt with a declared mode (build, plan, review, all) and a tag set. Copy one into your agent's configuration, or read it first: the structure is deliberately consistent across the library, so knowing one prompt tells you how the others are organised.

plan and review prompts analyse without editing. build prompts are licensed to write code. For multi-area work, start with orchestrate, which spawns a sub-agent per area so the main session holds a plan rather than a transcript.

Not every prompt here has been run against a real codebase. The Verified column in the tables below says which have, and the verification register is the record behind it — including which prompts have not been run, why one of them could not be, and which one was checked against a corpus of a different kind from the rest.

Contributing¶

Prompts are added as files under prompts/ with the frontmatter contract below. Run the two generators, then open a pull request.

---
title: Display Name
description: One line, shown in index tables and search results
mode: build # build | plan | review | all
model: any
category: architecture
tags: ["lowercase", "kebab-case"]
---

Field	Rule
`title`	Display name. Must match the file's H1.
`description`	One line. No trailing period.
`mode`	One of `build`, `plan`, `review`, `all`.
`model`	`any`, or a pinned model ID. Default to `any`.
`category`	Must be a key in `scripts/apply_categories.py`.
`tags`	Lowercase kebab-case. Reuse existing tags where one fits.

Adding a prompt touches three files: the prompt itself, its title and category entries in the two generator scripts, and an entry in the nav: block of mkdocs.yml. Skipping the nav entry is the easy mistake, because MkDocs still builds an unlisted page — it just never appears in the sidebar.

python3 scripts/apply_titles.py           # frontmatter title + H1
python3 scripts/apply_categories.py       # category key
python3 scripts/fix_heading_hierarchy.py  # one H1 per document
python3 scripts/generate_index.py         # tables in this file
scripts/validate.sh                       # schema, nav, links, lint

CI runs the same checks, so a stale index.md, a malformed frontmatter block, or a prompt missing from the nav fails the pull request rather than reaching the site.

See CONTRIBUTING.md for the full review criteria.
