How Dorsal Improved a Real Product

Keelo.AI builds AI agents for enterprise clients. It checks its design decisions with Dorsal, and Dorsal reviews its pull requests.

“Always using it. It influences almost every plan stage for us.”

One repo per customer, with the agents inside. Claude Code had recommended one repo per agent.

Dorsal: “the repo boundary is the ownership boundary”, from 7 records including Microsoft’s ADR-0032 (2026-07-21)

decision record 0095 · commit e114651 · prevents Bad Design

Fixed why no release could install on the Amazon Linux 2023 boxes: the path check now resolves the lib64 symlink before comparing.

Dorsal: NVIDIA garak hit the identical failure and fixed it by resolving both sides (garak #1860).

2026-09-14 · commit a47eb53 · prevents Faulty Code

The build gate now catches a broken eval it used to announce as finished. It compares failing check ids against the base, in place of the exit code.

Dorsal: TensorRT-LLM’s CI hid added regressions by exempting a whole case on a regressed base; Qwen Code compares the set of failures.

2026-09-14 · commit 531d8d98 · prevents Silent Failures

Each fix is one commit on its own branch, checked by a second agent: the proof fails before the fix and passes after. Keelo adopted some of them.

Quoted from Keelo’s decision record and the pr-fix handover.

Two steps, about a minute

Install Dorsal

Claude Code checks Dorsal before each major decision.

  1. 1

    Connect Dorsal to Claude Code

  2. 2

    Tell Claude Code 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 Claude Code. It loads both at startup.

The spec

What a check runs on, measured

Ranked by what matters most in a check. Independence first.

LLMs between the record and Claude Code

Zero

Retrieval is deterministic. Claude Code does the judging, with your project context.

Claims that open to a source

100%

Every record links to its origin and carries its date. When the graph has nothing, Dorsal says "no record found" instead of guessing.

Freshness

24h

The graph updates daily. The date is on every record.
