From 0dbae2f75dbd3f69e23c1d3a318a22aae7491304 Mon Sep 17 00:00:00 2001 From: khaliqgant Date: Thu, 8 Oct 2026 19:35:19 -0700 Subject: [PATCH 1/3] feat(babysitter): standalone fixer that proposes a patch and never pushes F2 in the Babysitter owner plan (Revision 1, approved by the lead). The fixer keeps only the run's read and comment token. It checks out the bound head, runs one agent there with the origin session's scope, and journals one bounded proposal: a patch against the bound head plus thread replies. Cloud publishes the proposal server-side as a fast-forward-only commit; FIXER.md is the contract. RULING-sandbox-push-0902 forbids push credentials in sandboxes. - admission.ts: admission prelude shared with the diagnose body, extracted unchanged; every standalone test still passes. - fix.ts: checkout, using the token as a header, never in argv or config, and reusing an existing checkout. Proposal limits: 36KB patch, 50 files, 50KB total; workflow and secret paths are refused. - fixer.ts: the body. Replies go only to inline feedback that woke the run, are marked and neutralised, and the origin prompt is redacted. - Builtins load with import(), not require(). esbuild rewrites require into a __require shim that does not exist under `node -e`. A test runs the function lifted out of the shipped artifact; it was mutation-checked. - build-standalone.mjs builds both artifacts; the drift gate covers both. - shipped-source audit: a call-exact waiver for "babysitter-fix", like #616's "babysitter-diagnose".

Cloud launches it +the same way it launches the diagnose-only `standalone.ts` (STANDALONE.md, "Launch +input"). Admission is shared (`admission.ts`): it admits only the bound PR, fails +closed without origin context, binds the live head to the server-claimed head, +applies the Software Garden / `babysit` label scope, and declines when nothing is +actionable. + +The exact deployable source is `artifacts/babysitter-fixer.flow.ts`. Its byte +count and SHA-256 are in `artifacts/babysitter-fixer.manifest.json`. Merging this +enables nothing: Cloud must admit that digest (see "Cloud contract" below). + +## Why it proposes instead of pushing + +The sandbox never holds a push credential. Cloud's PR head mode writes a +contents-write token to a file the same-uid agent can read. A GitHub App token +cannot be limited to one branch, so a prompt-injected agent could push anywhere +in the repository. Cloud's `RULING-sandbox-push-0902` forbids push credentials +in sandboxes. The run therefore keeps only the read and issue-comment token +from #4226, and Cloud publishes server-side. + +## Body, after admission + +1. **Check out the bound head** in `babysitter-checkout` under the run root. + - The read token is sent as an HTTP header through `GIT_CONFIG_*`, never in + argv or in `.git/config`. Hooks are disabled. + - An existing checkout (a reused sandbox) is fetched, reset to the head and + cleaned in place. Ignored files, such as installed dependencies, survive. +2. **One agent** (`babysitter-fix`, the origin session's CLI) runs in that + checkout. Its task opens with the origin's first prompt, verbatim and + fenced, then lists what changed with review comment ids. It is told to edit + only, to never touch workflows or secrets, and to end with + `{"summary", "replies": [{id, body}]}`. +3. **Reread before proposing.** If the head moved or the PR left scope, the + run declines with no proposal. +4. **One journaled proposal**, the stdout of one deterministic `f.run`: + ```jsonc + { + "kind": "babysitter-proposal", "schemaVersion": 1, + "pullRequest": { "owner": "acme", "repo": "widgets", "number": 7 }, + "baseHead": "", + "files": ["src/queue.ts"], // git diff --name-only --no-renames + "patch": "diff --git …", // git diff --cached --binary --full-index + "summary": "", // ≤ 4,000 chars, origin prompt redacted + "replies": [{ "commentId": 11, "body": "\n…" }] + } + ``` + - The patch includes the agent's own commits, because it is taken against + the bound head. + - Limits: patch ≤ 36,000 bytes, ≤ 50 files, whole proposal ≤ 50,000 bytes + (the kernel keeps a 64 KiB stdout tail). + - Any path under `.github/workflows/`, `.env*`, keys and certificates, + `id_*` SSH keys, `.npmrc`/`.netrc`/`.pypirc`, or `secret(s)/` makes the + run print `{"kind": "babysitter-refusal"}` instead.

Before this change, the daemon's `git add` and `git diff` would execute an agent-planted external diff or clean filter, with the daemon's token in the environment. The diff settings could also change the patch format that Cloud parses. The red capture shows the pre-fix code running both planted drivers. Both scripts now replace .git/config with a minimal known config and remove hooks and info/attributes before any git command. The checkout script does this because a reused checkout's fetch carries the token. The proposal diff also passes --no-ext-diff --no-textconv and fixed a/ b/ prefixes.

The fixer now calls f.agent with a literal cli/model pair per origin CLI (claude/claude-sonnet-5, codex/gpt-5.6-sol), so the unmodified audit resolves both pairs. The fixer ignores the policy's agentCli. - Restore tests/standalone-artifact.test.ts from #633 unmodified. The build prints "Checked sha256: ()", which that test accepts. The fixer artifact and the no-__require check are in the new tests/fixer-artifact.test.ts. - Read changed paths NUL-delimited, and diff with core.quotePath=false. A path git would still quote (quote, backslash, control char) refuses the proposal, so a newline cannot split a workflow path past the rule, and Cloud parses back exactly the checked paths.
