aget-check-evolution

aget-check-evolution is a skill for Claude Code from aget-framework/aget. It costs 34 tokens per session (936 once invoked), scanned A, original, Apache-2.0.

A health checker for the .aget/evolution/ folder, where an agent’s evolving instruction documents are stored. It counts files, checks their types and names, measures disk usage, and verifies the index file.

In plain words
What is it for?
Use it to inspect the folder’s inventory, naming rules, disk use, and whether its index.json file contains valid JSON.
Why use it?
It helps detect missing, misnamed, unexpected, or excessive evolution records before the folder becomes unreliable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

aget-check-evolution scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/aget-check-evolution

Monitor the health of the .aget/evolution/ directory by checking file counts, types, naming conventions, and disk usage.

Purpose

Provide self-diagnostic capability for AGET agents to assess their evolution directory health without supervisor intervention.

Execution

When invoked, perform these checks:

1. File Inventory

# Count total files
find .aget/evolution -type f | wc -l

# Count by extension
find .aget/evolution -type f -name "*.md" | wc -l
find .aget/evolution -type f -name "*.json" | wc -l
find .aget/evolution -type f ! -name "*.md" ! -name "*.json" | wc -l

2. Naming Convention Check

Valid L-doc pattern: L###_*.md (e.g., L588_skill_invocation_control_semantics.md)

# Count valid L-doc names
find .aget/evolution -type f -name "L[0-9][0-9][0-9]_*.md" | wc -l

# Find non-conforming files (excluding index.json)
find .aget/evolution -type f ! -name "L[0-9][0-9][0-9]_*.md" ! -name "index.json" ! -name "README.md"

3. Disk Usage

du -sh .aget/evolution

4. Index Integrity

Check that index.json exists and is valid JSON:

test -f .aget/evolution/index.json && jq empty .aget/evolution/index.json 2>/dev/null && echo "valid" || echo "invalid"

Thresholds

Metric OK WARN CRITICAL
Total files <500 500-750 >750
Non-standard files 0-10 11-50 >50
Disk size <10MB 10-25MB >25MB
Index integrity valid - invalid

Note: Thresholds inherited from supervisor defaults. Research AGET baseline (2026-02-08): 94 files, 800K - well within OK range.

Output Format

Report the following:

=== /aget-check-evolution ===

Directory: .aget/evolution/

File Counts:
  Total:     [count]
  L-docs:    [count] (.md matching L###_*.md)
  Index:     [1 if exists, 0 otherwise]

Disk Usage: [size]

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
