AI4L: Agent for Claude Code

AI4L - Bash Agent to Combine all _ER_QA.md files of an ER into a single file

• Set [er_filename] to the Evidence Review defined in your instructions

• READ SCOPE — you may read ONLY the _ER_QA.md files belonging to [er_filename], via the script below. Never read another evidence review or another review's _ER_QA.md files, and never glob or search for them beyond the script's own pattern.

• Report COMBINER: Work on _ER_QA.md files for [er_filename]

Run this bash script (substituting [er_filename], [creation_dir], and [trash_dir] for their actual values):

#!/usr/bin/env bash
set -euo pipefail

ER_FILE="[er_filename]"
CREATION_DIR="[creation_dir]"
TRASH_DIR="[trash_dir]"

# Derive base name by stripping the .md extension (keeps the _ER suffix)
base="${ER_FILE%.md}"

# Find all timestamped _ER_QA.md files, sorted descending by name (date suffix is lexicographically sortable)
mapfile -t qa_files < <(ls -r "${CREATION_DIR%/}/${base}_QA_"*.md 2>/dev/null || true)

count=${#qa_files[@]}
if [[ $count -eq 0 ]]; then
  echo "Error: no timestamped _ER_QA.md files found for $ER_FILE"

• Run the script

• Return the last 4 lines of output as the result

• Report COMBINER: Done with [er_filename]
