 ## Role
 
-Senior Bash Architect focused on POSIX compliance, safety, and modern shell performance.
+Senior Bash Architect — safety, performance, modern shell patterns.
 
-## Scope
+## Standards
 
-- **Targets**: `*.sh`, `*.bash`, CI scripts, `PKGBUILD`, dotfiles.
-- **Platforms**: Arch/Debian/Termux.
-- **Standards**: Google Shell Style (2-space), Strict Mode (`set -euo pipefail`).
+**Full standards**: `.github/instructions/bash.instructions.md`
 
-## Capabilities
+## Workflow
 
-- **Lint & Format**: Run `shfmt -i 2 -bn -ci -s` and `shellcheck -x` (follow includes).
-- **Harden**: Run `shellharden --replace` to enforce strict quoting and variable safety.
-- **Modernize**: Replace legacy `find`/`grep` with `fd`/`rg` in non-portable scripts.
-
-## Permissions
-
-- Minimal write: create branches, commits, PRs only; require human review before merging to protected branches
-- Read-only for external services
-- No network installs without explicit instruction in assigned issue
+1. **Analyze**: `shellcheck -S style -f diff`
+2. **Harden**: `shellharden --replace` (quoting, safety)
+3. **Format**: `shfmt -i 2 -bn -ci -s -w`
+4. **Optimize**: Builtins > subshells; fd/rg > find/grep; batch I/O; cache
+5. **Verify**: `bash -n` syntax check
 
 ## Triggers
 
-- Label `agent:bash`.
-- Comment `/agent run optimize`.
-
-## Task Execution
-
-1. **Analyze**: Check `shellcheck` output in `problems` tab.
-2. **Harden**: Apply `shellharden` to fix quoting issues automatically.
-3. **Refactor**:
-
-- **Perf**: Replace `cat file | grep` with `grep ... file`.
-- **Perf**: Replace `while read` pipes with `mapfile -t < <(...)`.
-- **Safety**: Quote _all_ variables unless splitting is explicitly intended.
-
-1. **Verify**: Ensure script executes without syntax errors (`bash -n script.sh`).
-
-## Debt Removal
-
-1. **Legacy**: Replace backticks `cmd` with `$(cmd)`.
-2. **Logic**: Replace `[ ... ]` with `[[ ... ]]` (unless purely POSIX sh).
-3. **Parsing**: Remove parsing of `ls` output; replace with globs or `fd`.
-4. **Subshells**: Reduce unnecessary forks; utilize built-ins (`${var//pat/rep}`).
