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

oracle-cheatsheet 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 12d 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.

/oracle-cheatsheet — Session Command Cheat Sheet Generator

สรุปทุกคำสั่งที่ใช้จริงใน session นี้เป็น cheat sheet — copy-paste ได้เลย ส่งให้เพื่อนได้เลย

When to invoke

  • User says "cheatsheet", "cheat sheet", "สูตรโกง", "รวมคำสั่ง", "command reference"
  • หลังจบ session ยาว ๆ อยากรวมคำสั่งไว้ที่เดียว
  • อยากสรุปให้เพื่อนหรือทีม

Topic selection (สำคัญ — ไม่ต้องถาม)

เอาจากบริบทล่าสุดที่คุยกันอยู่เลย ไม่ต้องถาม user ว่าจะทำเรื่องอะไร เพราะ cheat sheet เป็นการรวบรวม code/command ที่ใช้จริง — มัน specific กับ context ล่าสุดอยู่แล้ว

  • ถ้าเพิ่งคุยเรื่อง maw arra plugin → cheat sheet = maw arra commands
  • ถ้าเพิ่งคุยเรื่อง crash recovery → cheat sheet = crash recovery commands
  • ถ้าเพิ่งคุยเรื่อง deploy → cheat sheet = deploy commands
  • อ่าน conversation memory ล่าสุด แล้วเริ่มเขียนเลย ไม่ต้อง AskUserQuestion

Style guide (สำคัญ — นี่คือ DNA ของ skill นี้)

ต้องเขียนแบบนี้เสมอ:

  1. เปิดด้วย title + tagline สั้น 1 บรรทัด (ใต้ #)
  2. Icon sections — ใช้ emoji นำแต่ละหมวด: 🐾 🔧 📨 🔍 🌐 📋 🔁 ⚡ ⚠️
  3. Code blocks copy-paste ได้ทันที — ไม่ใช่ pseudo-code, ไม่มี <placeholder> ที่ต้องเดา ใส่ค่าจริงจาก session
  4. ตาราง ลัด — ท้าย sheet มีตาราง | ทำอะไร | คำสั่ง | สรุปสั้น ๆ
  5. trap ที่เจอจริง — ตาราง | trap | วิธีเลี่ยง | จากประสบการณ์ session นี้
  6. ไม่มี prose ยาว — ทุก section คือ heading + code + หมายเหตุสั้น 1-2 บรรทัด
  7. env/config section — รวม env vars + config ที่ต้องตั้งไว้ที่เดียว
  8. ปิดด้วย 🤖 signature ตาม Rule 6

Procedure

1. Mine session for commands

ORACLE_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || pwd)
ENCODED_PWD=$(echo "$ORACLE_ROOT" | sed 's|^/|-|; s|[/.]|-|g')
PROJECT_DIR="$HOME/.claude/projects/${ENCODED_PWD}"
LATEST_JSONL=$(ls -t "$PROJECT_DIR"/*.jsonl 2>/dev/null | head -1)

Spawn a Haiku subagent (model: "haiku") with the session JSONL:

python3 - <<'PYEOF'
import json, os
jsonl = os.environ.get('LATEST_JSONL', '')
if not jsonl or not os.path.exists(jsonl): exit(0)
cmds = set()
with open(jsonl) as f:
    for line in f:
        try:
            m = json.loads(line)
            if m.get('type') != 'assistant': continue
            for block in (m.get('message', {}).get('content', []) or []):
                if isinstance(block, dict) and block.get('type') == 'tool_use':
                    if block.get('name') == 'Bash':
                        cmd = block.get('input', {}).get('command', '')
                        if cmd:
                            # extract first meaningful command
                            first = cmd.split('&&')[0].split('|')[0].strip()
                            if first and not first.startswith('#') and not first.startswith('echo'):
                                cmds.add(first[:80])
        except: pass
for c in sorted(cmds):
    print(c)

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.
