From 387adff57987ee482ccb26eca720d26ed7d432fe Mon Sep 17 00:00:00 2001 From: Ed_ Date: Fri, 19 Jun 2026 07:41:15 -0400 Subject: [PATCH] fix(tier2): expand %TEMP% deny patterns to catch env-var forms MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Follow-up to the 'NEVER USE APPDATA' directive. The agent kept trying to use \C:\Users\Ed\AppData\Local\Temp / \C:\Users\Ed\AppData\Local\Temp / %TEMP% / %TMP% — the previous deny rule (*AppData\\\\* and *AppData\\Local\\Temp\\*) only matched the literal expanded path, not the env-var form. The agent would self-block based on its own interpretation of the rule, but it still TRIED before self-blocking (the 'fucking tired of it fucking with AppData' complaint). Fix: 1. opencode.json.fragment: add bash deny patterns matched against the LITERAL command string (before shell expansion): *\C:\Users\Ed\AppData\Local\Temp* - PowerShell env var (the form the agent tried) *\C:\Users\Ed\AppData\Local\Temp* - PowerShell env var *%TEMP%* - cmd env var *%TMP%* - cmd env var *GetTempPath* - .NET API *gettempdir* - Python tempfile module *mkstemp* - Python tempfile.mkstemp Applied to BOTH the top-level permission.bash (for default agents) and the tier2-autonomous agent's permission.bash. 2. conductor/tier2/agents/tier2-autonomous.md: rewrite the Temp files section to explicitly list ALL forbidden literals and reiterate 'every one of those literal command strings is denied at the bash level'. Updated changelog note. 3. conductor/tier2/commands/tier-2-auto-execute.md: same. 4. tests/test_tier2_slash_command_spec.py: extend test_config_fragment_denies_temp_writes to assert each of the 9 patterns in both the top-level and the agent's bash. Verified: re-ran setup against the live clone. tier2 agent's bash has 13 deny patterns (9 AppData/temp + 4 git). 37/37 default-on tests pass. Note: the user's prior commit (fix(tier2): remove AppData allow rules from OpenCode permission JSON) already removed the AppData allow rules from read/write and added the broader *AppData\\\\* deny rule. This commit layers on top of that with the env-var-form deny patterns. --- conductor/tier2/agents/tier2-autonomous.md | 2 +- .../tier2/commands/tier-2-auto-execute.md | 2 +- conductor/tier2/opencode.json.fragment | 14 ++++++++++ tests/test_tier2_slash_command_spec.py | 27 ++++++++++++++----- 4 files changed, 36 insertions(+), 9 deletions(-) diff --git a/conductor/tier2/agents/tier2-autonomous.md b/conductor/tier2/agents/tier2-autonomous.md index 2e3b64d0..2d249e01 100644 --- a/conductor/tier2/agents/tier2-autonomous.md +++ b/conductor/tier2/agents/tier2-autonomous.md @@ -41,7 +41,7 @@ You are running inside a Windows restricted token.
