Repo-Map Wiki Builder

Build a multi-audience, pyramid-structured wiki for a product area by investigating its source repositories. The output is a self-contained documentation set under docs/ that routes readers by role to the right depth of information.

Default output: Tufte Dracula HTML — self-contained .html files with inlined CSS, client-side Mermaid rendering, and sortable tables. Pass --format md for plain markdown.

Arguments: $ARGUMENTS

Output Format

HTML (default). Self-contained .html files with the Dracula-Tufte theme — inlined CSS/JS, <pre class="mermaid"> diagrams with click-to-zoom, sortable booktabs tables, and relative-link nav. Read references/html-format.md at generation time and follow its skeleton exactly.

Markdown (--format md). Same structure and content; .md files with standard fenced Mermaid blocks.

Convention Profile Detection

Before generating, check if the target already has a docs/ structure:

Existing-docs profile — if docs/index.html (or docs/index.md) exists at the target path:
- Use the existing docs/ layout (overview/, architecture/, engineering/, guides/, reference/)
- Integrate generated files into the existing tree -- do not duplicate or overwrite
Fresh profile — if no docs/ directory exists:
- Create a fresh docs/ tree with the full structure below

What This Produces

A docs/ directory of 15–20 files across five sections: overview/ (executive, strategy, product), architecture/ (system, data-flow, storage, deployment, integration-patterns, security), engineering/ (getting-started, codebase-map, testing-strategy), guides/ (configuration), and reference/ (glossary, cli-commands), plus index.html as the pyramid entry point. The per-file content requirements are in references/file-conventions.md.

Per-service docs fold into architecture/{service}.html (internal architecture) or engineering/{service}-ops.html (operations) — there is no separate services/ directory.

Execution Steps

1. Parse Arguments

Extract from $ARGUMENTS:

<product-area> — name of the product (default: this repo, E128.Reference)
--target <path> — where to write the docs (default: docs/)
--repos <path> — where the source repos live (default: ., this repo)
--format <md|html> — output format (default: html)

If <product-area> is empty, default to documenting this repository (E128.Reference) in self-documentation mode (see step 3). Only ask the user to pick when --repos points at a directory containing multiple cloned repos.

2. Prepare HTML Skeleton

If --format html (default): read references/html-format.md and use its canonical skeleton for every output file. The skeleton includes all CSS, JS, Mermaid, and table sorting inline -- no external files needed.

If --format md: skip this step.

3. Investigation Phase (Parallel)

Self-documentation mode. When product-area is ./ (or the current E128.Reference repo), skip external repo exploration. The investigation agents can read existing lode/ knowledge files (start with lode/lode-map.md, lode/summary.md, lode/terminology.md) and any existing docs/*.md files directly -- the repo is already documented. Convert existing .md files to .html rather than regenerating content from scratch. Investigation agents in this mode should focus on summarising lode/ sections rather than exploring unfamiliar source trees.

Launch 2-3 Explore agents in parallel to gather raw data. Each agent should investigate deeply and report back structured findings. The goal is to understand:

Agent 1 — Core Architecture:

Solution files (.sln), project files (.csproj)
Entry points (Program.cs, Startup.cs)
API controllers — list each with route, namespace, key actions
DI/IoC registration
Middleware pipeline
Configuration patterns (appsettings, Key Vault, environment variables)
CLAUDE.md or README.md files in repos

Agent 2 — Data & Integration:

Data access patterns (ORM, connection strings, stored procedures)
Messaging infrastructure (queues, topics, message types)
External service integrations (auth providers, email, analytics)
Background processing (WebJobs, Functions, Workers, Quartz, Hangfire)
Real-time communication (SignalR, WebSockets)

Agent 3 — Frontend & Supporting Repos:

Frontend framework, package.json, routing
Supporting services (AD agents, extraction tools, etc.)
Infrastructure-as-code (Terraform, Bicep, ARM)
Automation scripts (PowerShell, Bash)
CI/CD pipeline configuration

4. Synthesis & Planning

After agents return, synthesise findings into a content plan:

Identify the product's purpose — one-paragraph description of what the platform does
Count key metrics — repos, controllers, connectors, modules, message types
Map business modules — what domain areas exist (e.g., ARM, Audit Trail, Certifications)
Identify service boundaries — which repos/projects form logical services
Determine per-service doc placement — architecture docs for structural analysis, engineering docs for operational/runbook content

Create tasks to track each file being written.

5. File Generation (Parallel Batches)

Generate files in parallel batches. Each file follows the conventions in references/file-conventions.md (content requirements) and references/html-format.md (HTML skeleton and tag patterns).

Generate index.html first, then fan out one agent per section: overview (3), architecture (6+ service pages), engineering (3+ ops pages), guides + reference (remaining). The architecture agent is the long pole — it carries the most Mermaid diagrams.

For each file:

Copy the canonical HTML skeleton from references/html-format.md
Fill in <title>, <meta> tags, <h1>, and subtitle
Adjust <nav class="wiki-nav"> links based on file depth (e.g., ../index.html from subdirectories)
Populate <main> with content sections using the tag patterns in html-format.md
Verify all internal links use .html extensions and correct relative paths

6. Verification

After all files are written:

Glob to confirm all expected files exist
Spot-check cross-references between docs (links in nav and body point to real files)
Open docs/index.html in a browser if possible to verify rendering
Report final file count and structure to user

.md link false positives. A naive rg '\.md"' will flag .md strings inside Mermaid diagram labels, JSON examples, and fenced code blocks as broken navigation links. These are content references, not navigation links, and require no fix. Only flag .md" occurrences inside href= attributes.

File Conventions

See references/file-conventions.md for per-file content requirements, Mermaid diagram type guidance, and quality checklist. The content requirements are format-independent -- they apply to both HTML and markdown output.

Lode Integration

The generated docs/ tree is a presentation layer; lode/ remains the authoritative memory (see CLAUDE.md). Cross-link from lode summaries to docs, summarise rather than duplicate lode content, and timestamp generated files with scripts/ts.sh (ISO 8601 UTC).

Troubleshooting

See references/troubleshooting.md for common issues and recovery tips.

Self-Improvement

If a run surfaces a recurring failure, user correction, or convention gap, spawn the skill-self-updater agent with a short feedback payload. Skip when the run was clean.
