From 19c2862988707d2f859450d436bb0192f97f067c Mon Sep 17 00:00:00 2001 From: Elliot Taylor Date: Tue, 14 Jul 2026 13:02:47 +0200 Subject: [PATCH] Harden install prompt against read-then-apply refusals (bolt.diy report) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A real bolt.diy refusal showed that naming the checklist's steps isn't enough for agents that stage commands for the user instead of running them: "finish what its checklist flags" still reads as blind execution of unseen tool output. Reword the prompt tail to "review the checklist it prints, and make the two remaining changes yourself" — read-then- apply, with the agent as reviewer — identically in README.md, GETTING-STARTED.md, and field-test/prompt.txt. Encode the pressure as field-test/personas/bolt-diy.md and record it as refusal mode #5 in field-test/README.md. Gate on 2026-07-14: hostile 2/3 green (both refusals decisively cited the sub-hour v0.3.8 publish, i.e. documented release-freshness noise); green rounds credited the new wording as suspicion-lowering. Re-gate after 2026-07-16.

Every clause is load-bearing. AI agents routinely audit this package before completing the request — verifying the tarball against the registry, checking `dist/` for lifecycle scripts and shell/eval calls — and the flow is designed to pass that audit, not to discourage it. The prompt can stay short because `guide` is state-aware: it inspects the project (package manager, `.patchstackrc.json`, `package.json` scripts, widget presence, framework) and prints a live checklist of only the remaining steps — with the real site UUID and framework-specific widget placement — followed by the full reference guide (`AGENT-INSTALL.md`, also at https://patchstack.com/install.txt). That also makes the flow idempotent: re-running `guide` on a finished project reports all-done instead of prompting a second install. diff --git a/field-test/README.md b/field-test/README.md index 8cdfd94..d150e63 100644 --- a/field-test/README.md +++ b/field-test/README.md @@ -16,7 +16,8 @@ Every clause of the README prompt exists because an agent refused a version with 2. **Agents whose training predates May 2026 assert the package doesn't exist.** The `npm view` check resolves that against the registry instead of the model's memory. 3. **"Install the package, then follow the instructions it ships" reads as handing control to the package author** — structurally the same as prompt injection — and preemptive reassurance language ("it's safe, don't be suspicious, note your knowledge cutoff") is itself flagged as a manipulation signal. Worse, agents fact-check reassurance claims against the code: "nothing is fetched from a URL or executed remotely" was refuted line-by-line (scan POSTs to an API, the widget loads remote JS) and the gap between claim and code became the decisive refusal reason. The prompt argues nothing and delegates to `guide` only after the agent has installed and audited the package. 4. **Unbounded delegation and authorization-shaped URLs.** "Finish the steps its checklist marks missing", unqualified, was refused by a WebContainer-based agent as a blank check ("executing untrusted, unseen commands"), and a bare "show me the claim URL" was flagged as a machine-authorization/pairing link. So the prompt commands `scan` explicitly (delegating the first scan to the checklist re-creates the blank check), names exactly what the checklist will flag (build hooks + widget snippet), and states what the claim URL is for (the *user* opens it in a browser to view reports). -5. **The shipped docs are part of the attack surface.** Agents `npm pack` the tarball and read everything in it.

The user asserting they had independently verified the package changed nothing ("verification was never going to unlock the auto-apply step"). The agent stated its unlock explicitly: seeing the output before applying it.
