aget: Skill for Claude Code

.claude/skills/aget-check-evolution/SKILL.md

aget-check-evolution is a skill for Claude Code from aget-framework/aget. It costs 34 tokens per session (1,548 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 15d 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 — 161 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. First verify .aget/evolution/ is a readable directory and the required tools (find, wc, du, jq, Python 3) are available. If a tool or inventory operation fails, report UNAVAILABLE with the failed check; do not turn incomplete readings into an OK result. These checks inspect filenames and JSON syntax, not lesson schema conformance or index-to-file references.

Run each shell block in Bash and inspect its exit status. A nonzero inventory/naming/disk exit means that reading is unavailable, regardless of partial stdout; discard its counts.

1. File Inventory

set -euo pipefail
# 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

Expected L-doc prefix and number width: L###_*.md or L####_*.md (three or four digits, as specified by AGET_LDOC_SPEC.md, CAP-LDOC-001). Examples: L588_skill_invocation_control_semantics.md, L1000_example.md. This check covers only the L prefix, three/four-digit number, underscore separator and .md extension. It does not validate snake_case titles, lesson contents, uniqueness or ID claims.

set -euo pipefail
# Count L-doc prefix/width matches (title conformance is not checked)
find .aget/evolution -type f \( -name "L[0-9][0-9][0-9]_*.md" -o -name "L[0-9][0-9][0-9][0-9]_*.md" \) | wc -l

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

What this file has done since we first saw it

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.
