From b3c7b3907972dbdbf11ad09240287cca96d47177 Mon Sep 17 00:00:00 2001 From: Jarek Potiuk Date: Thu, 24 Sep 2026 13:20:10 +0200 Subject: [PATCH] docs(setup): touch the hardware key for signatures, not for ssh transport The secure setup recommended a cached touch policy on both the signing and the authentication slot, so every git fetch, pull and push waited for a touch. Fetch and pull are reads, and a push is already confirmed by the git push ask rule and carries only commits signed with a touch, so the transport touch was a prompt that bought no control. Recommend `sig cached` plus `aut off` instead, keep `aut cached` only for gpg.format=ssh (where the aut slot is the one that signs), and update the install and verify skills and the hardware-key evals to match.

Every layer above bounds *which* commands run and asks the operator to confirm them, but a confirmation prompt is software, read by a human who has been reading prompts all afternoon. Layer 3b moves that confirmation into hardware for the signature — and deliberately not for the transport. Most authentications are reads (fetch, pull), and a touch on a read is exactly the prompt [PRINCIPLES.md §1](../../PRINCIPLES.md) rules out; a push is already confirmed by Layer 3's ask rule on `git push`, and everything it carries was signed with a touch. A second physical confirmation of the same push buys no control and spends the attention the signature touch depends on. -The reference setup supports keeping both secrets on a **hardware security key** — a YubiKey, Nitrokey, or any OpenPGP card — with a **touch policy** on the slots git reaches: the signature slot, and the authentication slot ssh uses.

With the touch policy set, the key does not sign until it is physically touched. A prompt injection that talks the agent into committing in the operator's name — the outcome every layer above exists to prevent — then ends at a key waiting for a finger that never comes, whatever the model was convinced of; a push can carry only commits that already passed that touch. The private keys never exist as files, so nothing the sandbox could leak reproduces them elsewhere. This layer is **fully optional** and additive. It is aimed at operators who want a physical check on the two irreversible operations, and at the many who already carry a security key because their employer issues one for SSO and ssh — the same key serves here at no extra cost. It covers every transport the framework supports: with an **https** remote the transport is the forge CLI's credential helper and the key only signs; with an **ssh** remote the key also authenticates the transport; and signing can be OpenPGP through gpg or an **ssh signature made by the same card** (`gpg.format=ssh`) that the forge verifies from a single uploaded key. Three pieces make it usable in an agent session rather than merely possible: -- **The key's own cache.** The recommended policy is `cached`: a touch is required and then honoured for 15 seconds on that slot. One touch covers a rebase that replays a dozen signed commits, a pull followed by a push, or the burst of fetches an IDE fires. The cache lives in the key, not in any host software, so no configuration on the host can extend it. (`ykman openpgp keys set-touch sig cached` / `aut cached`.) +- **The key's own cache.** The recommended policy on the signing slot is `cached`: a touch is required and then honoured for 15 seconds on that slot. One touch covers a rebase that replays a dozen signed commits. The cache lives in the key, not in any host software, so no configuration on the host can extend it. The authentication slot stays `off`. (`ykman openpgp keys set-touch sig cached` / `aut off`.) One exception: with ssh signatures (`gpg.format=ssh`) the signature is made by the authentication slot, so that slot carries the `cached` policy and the transport pays the touch too; OpenPGP signing, or an https remote, avoids it. - **The sandbox grants.** Layer 1 denies `~/.ssh/` and `~/.gnupg/` wholesale; the setup opens exactly two things — gpg-agent's ssh socket, so a sandboxed git can ask the key to sign and to authenticate, and the one public-key file git hands to `ssh-keygen` when signing with an ssh key. The private material stays on the card. - **The touch overlay.** A key waiting for a touch is indistinguishable from a hung command: gpg puts a pinentry window up for the PIN and nothing at all for the touch, and ssh simply blocks. The reference implementation ships a `PreToolUse` / `PostToolUse` hook, [`tools/agent-isolation/gpg-touch-overlay.sh`](https://github.com/apache/magpie/blob/main/tools/agent-isolation/gpg-touch-overlay.sh), that arms a watcher before any git command that can reach the key and puts a full-screen window on the desktop once the key has actually blocked — for a signature, by seeing the signing process wait; for ssh transport, by seeing a connection to the agent's socket stay open, since the ssh git spawns looks the same blocked on the key as it does transferring. The window dims the desktop the way pinentry does, closes itself when the touch lands, and stays hidden for the sub-second signatures a cached touch allows. The same script is also installed as git's own signing program and ssh command (`gpg.ssh.program` / `gpg.program`, `core.sshCommand`), where it runs the real program with the watcher alive for exactly that long — so a commit or push the operator makes from a terminal, where no hook of the agent's runs, gets the same window. diff --git a/docs/setup/sandbox-troubleshooting.md b/docs/setup/sandbox-troubleshooting.md index 687e9de39..8c6c40d47 100644 --- a/docs/setup/sandbox-troubleshooting.md +++ b/docs/setup/sandbox-troubleshooting.md @@ -285,9 +285,11 @@ Per-entry rationale: not the outcome, as long as that proxy wants credentials `nc` cannot offer — `This proxy requires authentication, and this client did not offer an authentication method` (Claude Code on - macOS, 2026-09).
