02Thorsten Freitag/Dependencies

Less to maintain.
Versions pinned.

A Dorsal-backed review led Thorsten to approve a dependency cleanup. His coding agent removed 43 unnecessary packages and pinned the remaining versions.

03Waterius/Firmware tests

Outside evidence.
A fix tested on the bench.

Dorsal supplied evidence for a finding in Waterius’s firmware-test audit. The resulting fix was accepted and verified on the live bench.

Two steps, about a minute

Claude Code checks Dorsal before each major decision.

  1. 01

    Connect Dorsal to your coding agent

    One command, read-only, no account. The token is already in it.

    Read-only. Your data stays local.
    Run this in your terminal
    Preparing your secure install command…

    Preparing a temporary read-only token for the complete command…

    On your phone? Send the command to your inbox for later.

  2. 02

    Tell your agent when to use it

    Paste this into ~/.claude/CLAUDE.md for all your projects, or into one project’s CLAUDE.md. On Codex, use AGENTS.md.

    Add to CLAUDE.md
    ## Dorsal
Before you commit to a decision at any of these steps, check it against Dorsal:
- Product: what to build, and what others already shipped
- Architecture: the design, stack, libraries and data model
- Integrations: the current version of each API, SDK, library and model
- Code: known failures of the libraries you touch
- Production: how similar systems fail silently, and how they caught it
Cite the dated records you used. If Dorsal has nothing relevant, say so and go on.
Send Dorsal general questions only. Never code, file paths or secrets.

    Then restart your coding agent. It loads both at startup.

Skill + API

Or get Dorsal as a skill

The skill calls the Dorsal API over HTTPS when your agent needs evidence. Until then it adds 367 characters to the agent’s context. The MCP server adds 13,102. Same graph, same records. Works in Claude Code and Codex. Step 2 applies here too.
