Freeze — advisory edit scope
Apply a current-session instruction that limits which files this agent may edit.
This generated runtime does not install an enforcement hook, so the scope is
advisory rather than a technical lock. Never claim that edits are blocked by the
runtime.
Usage
phx-freeze
phx-freeze lib/app_web priv/repo
phx-freeze status
phx-freeze off
Treat the text after the skill invocation as follows:
| Invocation | Current-session behavior |
|---|
| No arguments | Do not edit files; investigation and reporting remain read-only. |
| Path prefixes | Edit only files under the listed project-relative prefixes. |
status | Report the advisory scope currently established in this conversation. |
off | Clear the advisory scope for subsequent work. |
Do not create .claude/.freeze. That sentinel belongs to the canonical Claude
Code plugin and could affect a later Claude Code session even though this runtime
cannot enforce or clear it reliably.
Iron Laws
- Never describe this scope as enforced — it is a binding instruction for
the current agent, not a runtime or security boundary.
- Never create or modify
.claude/.freeze in a generated runtime — no
matching enforcement component is installed here.
- Honor the active scope until the user clears it or the focused task ends —
ask before editing outside listed prefixes.
- Keep paths project-relative —
lib/foo includes that directory and its
descendants, not a sibling such as lib/foobar.
Native enforcement option
This skill remains advisory and never creates Claude's .claude/.freeze
sentinel. When the generated Amp plugin is installed, use the phx: edit lock
palette command for a persistent workspace lock enforced at Amp's tool.call
boundary. It blocks Amp-recognized edits outside the selected scope and disables
shell tools while active. Unknown third-party mutating tools remain outside
Amp's file-classification helper, so this is not complete Claude-hook parity.
