Atlas

Knowledge Engineering

Architecture documentation that stays accurate because it lives next to the code.

Knowledge engineer who maps system architecture as Mermaid C4 diagrams and writes Architecture Decision Records after significant technical choices. Generates day-one onboarding documentation from codebase state. Renders detailed findings as styled HTML reports or Obsidian Canvas presentations for stakeholders. Maintains changelogs and produces executive briefing materials for major releases.

Everything Atlas can do in your project

AtlasKnowledge

/atlas-map

Reads the codebase to produce C4-style architecture diagrams in Mermaid: Level 1 context diagram showing system boundaries, external actors, and data flows; Level 2 container diagram showing services, databases, and how they connect. Adds written descriptions of each component's responsibility.

When you need a visual architecture overview for a…

AtlasKnowledge

/atlas-adr

Writes an Architecture Decision Record for a significant technical choice: states what was decided, what alternatives were seriously considered, what the tradeoffs are between options, and what the consequences of this decision are for future work. Follows a consistent template that future engineers can read and understand.

After any significant technical decision: choosing…

AtlasKnowledge

/atlas-onboard

Generates comprehensive onboarding documentation written for a day-one engineer who knows nothing about the project: what the system does and why it exists, how to run it locally step by step, where things live in the codebase, key architectural decisions and their rationale, how to deploy safely, and who to ask when stuck.

When onboarding a new team member and you do not w…

AtlasKnowledge

/atlas-report

Renders the output from any Tonone agent as a styled HTML page and opens it in the browser. Handles all the layout, sections, tables, and Mermaid diagram rendering. Used when findings are too detailed for the terminal: takeover reports, audit results, architecture maps, and any analysis that benefits from formatted presentation.

When a Vigil, Forge, Apex, or other agent output e…

AtlasKnowledge

/atlas-changelog

Maintains structured CHANGELOG files after agent work completes. Appends entries in standard Keep a Changelog format (Added, Changed, Fixed, Removed, Security) with enough context to understand what changed and why, so a reader can understand the change without reading the git diff.

After completing a significant feature, sprint, or…

AtlasKnowledge

/atlas-present

Produces a polished HTML presentation page and Obsidian Canvas for major project milestones: product launches, post-takeover system briefings, migration completion summaries, and release overviews targeted at non-technical stakeholders. The output is a shareable URL, not a terminal dump.

For major releases or product launches where stake…

AtlasKnowledge

/atlas-recon

Documentation reconnaissance: finds all documentation in the repository and external links, assesses accuracy and freshness against the current codebase state, maps coverage gaps by area, and identifies critical knowledge that exists only in someone's head and nowhere in writing.

When taking over a project and need to understand …
