Brief

Inspect has become a "digital coworker" at Ramp, producing over 75% of code after targeted investments in repo setup (sandbox precomputes like mypy and bytecode caching), infra and web testing tools, UI flows for human+AI reviews, aggressive performance tuning led by @_dylanga, a robust API, and cost/prompt optimizations to approach "just works" across teams.

Why it matters

Inspect now functions as a “digital coworker” at Ramp, claimed by @rahulgs on 2026-06-19: over 75% of code contributions at Ramp reportedly come from Inspect.

Key details

  • Engineering investments included repo-wide setup checks (dependency installs, runnable commands), sandbox precomputes (mypy, uv deps, bytecode caching, git clone), infra additions (Terraform plans), a parallel browser-testing agent for web, and backend use of mypy's experimental parallel mode to run fast in sandboxes.
  • Operational work focused on UI polish (human + AI reviews, diffs, child sessions, stats, fast voice input with real-time GPT), extreme performance tuning led by @_dylanga, a robust API for internal automation, and cost optimizations (removing tool bloat, flex API, model/reasoning-level choices, enforcing declarative prompts) to make Inspect 'just works' across eng, product, data, support, sales, and UXR.
Cleaned source text

inspect is now our digital coworker. 75%+ code at ramp now comes from inspect.

what we've invested in:

1. repo setup across every main repo: is every dep installed, every command able to run and is performant, every skill token efficient and installed. are all the tools available - are the unused tools removed? which mcps are bloated? what can we precompute and snapshot in the sandbox fs (mypy, uv deps, bytecode caching, git clone). every additional source of feedback improved the final PR quality: for infra we added terraform plans, for web we added a parallel browser testing agent, for backend we added mypy's new experimental parallel mode, fast enough to run in a sandbox

2. ui polish and closing the loop outside of github - human reviews, ai reviews, diffs, child sessions, stats, fast voice inputs with realtime gpt

3. insane performance obsession (mostly @_dylanga), chasing down every ms across sandbox boot, new prompts, db queries, network round trips

4. try to match or exceed local agent performance across all axes (tools, skills, performance, repo set up)

5. robust api - used for many other automations internally

6. cost optimization: tool bloat, flex api, picking the right model, reasoning level across models

7. making sure prompts are always declarative, and almost never imperative. fix this ✅ implement this feature ✅ use the datadog mcp to fix this ❌ use the db migration skill from this link ❌

it's a moving target but a unending emphasis on speed, defaults, repo setup has allowed us to get as close as we can to "just works" on any knowledge work tasks at ramp - eng, product, data, support, sales, uxr
