In @.github/workflows/test.yml:
- Line 11: Update the actions/checkout@v4 step to disable persisted checkout
credentials by setting persist-credentials to false, ensuring subsequent
pull-request-controlled scripts cannot access the checkout token through Git
configuration.
In `@agent-vm.setup.sh`:
- Around line 228-230: Update configure_mcp so both Claude and OpenCode MCP
configuration branches explicitly guard the jq-and-mv update sequence: on jq or
mv failure, remove the temporary config file and return a failure status,
ensuring invalid JSON or write failures propagate instead of allowing setup to
succeed without the server.
In `@agent-vm.sh`:
- Around line 801-805: Update the name command dispatch around _agent_vm_name so
directory arguments are resolved to canonical absolute paths before deriving the
VM name, matching the path normalization used by other VM commands. Reject
nonexistent directories before invoking _agent_vm_name, while preserving
existing argument handling for valid paths.
- Around line 960-963: Update the variable-presence logic in the get/has path
around the validated eval so it checks whether the variable is set using
${variable+x} rather than comparing against the __agent_vm_unset__ sentinel.
Print the stored value separately, preserving support for values exactly equal
to __agent_vm_unset__.
- Around line 853-859: Update _agent_vm_info to preserve the exit status of
_agent_vm_base_exists, _agent_vm_exists, and _agent_vm_running instead of
treating failures as false; emit unknown for each failed query while retaining
0/1 for successful absence/presence results and the existing output keys.
In `@README.md`:
- Around line 200-209: Update the README guidance around the ~/.agent-vm/env
secret workflow to document that injected secrets are readable by VM code and
could be exfiltrated by compromised agents or dependencies when networking is
available. Recommend --offline for sessions that do not need outbound internet,
while clarifying that --offline limits exfiltration but does not prevent VM code
from reading the injected secrets.
In `@test.sh`:
- Line 205: Update the bash -c invocations in the nolima command and the
corresponding commands around agent-vm usage to pass AGENT_VM_SH and other file
paths as positional parameters, rather than interpolating them inside
single-quoted shell text; preserve the existing command behavior while
supporting paths containing single quotes.

In `@agent-vm.sh`:

_agent_vm_name to suppress any output emitted by cd, while still capturing the
output of pwd as the sole normalized directory value. Preserve the existing
hashing and VM-name generation flow.

Abort before mv when a temporary-file operation fails.
This file does not enable errexit, so _agent_vm_env() can continue after a failed append or final printf. A partial $tmp can then reach mv "$tmp" "$file" and replace the existing environment file. Check each temporary-file operation and remove $tmp before returning on failure. This includes mktemp, chmod, the copy-loop writes, and the final printf.
