From 22ad3e5b6479b60f330df992d3c6ae18a97cffa2 Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Fri, 27 Mar 2026 08:42:19 -0600 Subject: [PATCH] =?UTF-8?q?fix:=20Codex=20filesystem=20boundary=20?= =?UTF-8?q?=E2=80=94=20prevent=20skill-file=20prompt=20injection=20(v0.12.?= =?UTF-8?q?10.0)=20(#570)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * fix: add filesystem boundary to all codex prompts Codex CLI can read files outside the repo root despite -s read-only. It discovers ~/.claude/skills/ and ~/.agents/skills/, treats SKILL.md files as instructions, and executes preamble scripts instead of reviewing code. Fix: prepend a boundary instruction to all 11 codex exec/review callsites across codex/SKILL.md.tmpl (3), autoplan/ SKILL.md.tmpl (3), and scripts/resolvers/review.ts (5). Add rabbit- hole detection rule and 5 regression tests. * chore: bump version and changelog (v0.12.10.0) Co-Authored-By: Claude Opus 4.6 --------- Co-authored-by: Claude Opus 4.6 --- CHANGELOG.md | 10 ++++++ VERSION | 2 +- autoplan/SKILL.md | 24 +++++++++++++-- autoplan/SKILL.md.tmpl | 24 +++++++++++++-- codex/SKILL.md | 56 ++++++++++++++++++++++++++++------ codex/SKILL.md.tmpl | 56 ++++++++++++++++++++++++++++------ office-hours/SKILL.md | 4 ++- package.json | 2 +- plan-ceo-review/SKILL.md | 5 +-- plan-eng-review/SKILL.md | 5 +-- review/SKILL.md | 4 +-- scripts/resolvers/review.ts | 15 ++++++--- ship/SKILL.md | 4 +-- test/gen-skill-docs.test.ts | 61 +++++++++++++++++++++++++++++++++++++ 14 files changed, 230 insertions(+), 42 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index d9dc1789a6c9f8fec2ca7b6bc3ff2cc55de85e62..141f0513adef3adb17f50ff7468ef8b883f20cd5 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -1,5 +1,15 @@ # Changelog +## [0.12.10.0] - 2026-03-27 — Codex Filesystem Boundary + +Codex was wandering into `~/.claude/skills/` and following gstack's own instructions instead of reviewing your code.
