/aget-check-sessions

Monitor the health of the sessions/ directory by checking file organization, naming conventions, and disk usage.

Purpose

Provide self-diagnostic capability for AGET agents to assess their sessions directory health. Detects organizational anomalies like date-based subdirectories which indicate non-standard structure.

Execution

When invoked, perform these checks:

1. Structure Check

# Check for date subdirectories (anomaly indicator)
find sessions -type d -name "20[0-9][0-9]-*" 2>/dev/null | wc -l

# Check for checkpoints subdirectory (expected)
test -d sessions/checkpoints && echo "yes" || echo "no"

2. File Inventory

# Count session files (excluding checkpoints)
find sessions -maxdepth 1 -type f -name "*.md" | wc -l

# Count checkpoint files
find sessions/checkpoints -type f -name "*.yaml" 2>/dev/null | wc -l

3. Naming Convention Check

Valid session pattern: session_YYYY-MM-DD_*.md

# Count valid session names
find sessions -maxdepth 1 -type f -name "session_20[0-9][0-9]-[0-9][0-9]-[0-9][0-9]_*.md" | wc -l

# Find non-conforming files
find sessions -maxdepth 1 -type f -name "*.md" ! -name "session_20[0-9][0-9]-[0-9][0-9]-[0-9][0-9]_*.md"

4. Disk Usage

du -sh sessions

Thresholds

Metric	OK	WARN	CRITICAL
Total files	<200	200-500	>500
Date subdirectories	0	1+ (anomaly)	-
Disk size	<50MB	50-100MB	>100MB

Note: Thresholds inherited from supervisor defaults. Research AGET baseline (2026-02-08): 77 files, 544K.
