“I don’t know” is fine — we give how to get evidence; we never invent interviews or payments.

This is the core pain assumption. Without it, there is no reason to build the tool.

How to get evidence: Interview 10-15 developers who use coding agents weekly. Ask: 'Has an agent ever broken something? What happened? What did it cost you in time or risk? What do

Q: Is the DIY-Docker workaround actually insufficient, or would developers just use free tools?

If Docker plus git branches covers the need, the wedge is too thin for a paid product.

How to get evidence: In the same interviews, map the current workflow in detail. Ask what they use today, what they dislike, and whether they have tried sandboxing. Then test the pr

04 Business breakdown

Who needs this

Solo developers and small engineering teams (2-10 people) who use AI coding agents (Claude Code, Cursor, Copilot, etc.) on a weekly basis and care about repo safety.

Job to be done

Let a coding agent work autonomously in an isolated environment, verify changes are safe, and return a clean diff — without risking the main repo, database, or secrets.

Why they might pay

If an agent mistake costs hours of debugging or a data loss incident, a $10-20/month safety layer is cheap insurance. The tool saves setup time versus manual Docker configuration.

Alternatives

Manual Docker containers, local git branches with careful review, CI/CD sandboxing, running agents on a throwaway VM, or simply not delegating risky tasks to agents.

Differentiation wedge

A one-command CLI that wraps any coding agent session in an isolated Docker sandbox (read-only repo mount, temp database, network restrictions) and outputs a clean diff for review.

OPC scope

Minimal — one command, one sandbox, one diff output. No dashboard, no team features, no cloud hosting initially.

Open questions

  • How often do coding agents actually break something in practice?
  • What is the typical cost (time and money) of an agent-caused incident?
  • Would developers trust a diff-based handoff, or do they need to see the agent's full session?
  • Is the pain acute enough for a paid tool, or is it a nice-to-have?
  • Which agent workflows (refactoring, test writing, bug fixing) most need sandboxing?

05 Search & acquisition

Primary channel:

Developer communities (Hacker News, Reddit r/ClaudeAI, r/cursor, dev.to), plus a free CLI tool that spreads by word of mouth.

Talking points

  • Let your coding agent loose — without the fear.
  • Your agent's next mistake should not cost you a database.
  • Run any coding agent in a disposable sandbox, review a clean diff.

Minimum experiment 06 Minimum validation experiment

One falsifiable step before you continue or stop.

Valid signal = real task completion, reuse, or pay intent — with observe + continue/stop.

Recruit 10-15 developers who use coding agents weekly (from your network, dev Discord servers, or Reddit).

Observe

How many report a specific agent-caused incident? What was the cost? What do they use today for safety?

Continue

At least 5 report a concrete incident or strong fear with a time cost attached.

Stop

Most say 'I just review the changes carefully' or 'Docker is enough' with no pain.

Build a 3-day minimal CLI: spin up a Docker sandbox, mount the repo read-only, run the agent inside, output a diff.

Observe

Does the tool work on a real repo without 2 hours of setup? Do test users actually use it more than once?

Continue

2-3 test users use it on a real task and say they would want it again.

Stop

Setup friction is too high, or users say 'I would just do this manually'.

Who is this validation for?

How should I read the score?

Current OPC feasibility score is 5/100. It is an AI-assisted executability check, not a market guarantee. Low scores mean “prove demand first,” not “never build.”

07 Evidence & boundaries

Demand evidence summary

No traceable demand evidence beyond a Hacker News keyword mention. Interest in the concept exists, but interest is not demand. The next step is to gather behavi

None

Model hypothesis

  • Developers using AI coding agents may fear unintended side effects (broken tests, mutated data, leaked secrets) and may want an isolation layer.
  • The cost of an agent mistake (debugging time, data loss, failed deploy) may exceed the cost of a sandbox tool, if mistakes happen with meaningful frequency.
  • Current workarounds (manual review, local branches, DIY Docker) may be adequate for cautious users but may fail for users who want to delegate more autonomy to agents.

Known facts

  • The keyword 'Droneship – sandbox for your coding agents' was submitted on Hacker News (user-provided).
  • AI coding agents (Claude Code, Cursor, Copilot, etc.) exist and are used by developers.
  • Docker is a widely available tool for creating isolated environments.

Unverified assumptions

  • Developers using coding agents have experienced or fear agent-caused damage.
  • A Docker-based sandbox wrapper is technically feasible for a solo developer in 5-7 days.
  • The pain is frequent enough to justify a paid tool rather than a free script.
  • Developers would trust a diff-based handoff from a sandboxed agent session.

AI inference: As coding agents become more autonomous, demand for safety and isolation layers may grow.,The sandbox concept appears in other domains (browser sandboxing, CI sandboxing), suggesting it is a familiar pattern.,The name 'Droneship' suggests an unmanned or autonomous vessel — a metaphor for letting agents work unattended.
