notebook-ask

notebook-ask is a command for Claude Code from MarcosNahuel/antigravity-plugin-cc. It costs 64 tokens per session (793 once invoked), scanned A, original, MIT.

A question-and-answer command for a local notebook corpus previously built with /agy:notebook. It reads the small summaries for each document and answers with citations instead of reading the original documents.

In plain words
What is it for?
Use it to ask questions about notebook summaries and receive answers linked to the documents that support them.
Why use it?
It provides a cheaper, focused way to query an existing document collection when the full source files are not needed.

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

notebook-ask 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.

Question-answering over a notebook corpus previously built by /agy:notebook. agy reads the small per-document summaries (not the originals) and answers with citations. Run /agy:notebook <folder> | <objective> first to build the corpus.

Raw user request: $ARGUMENTS

Phase 0 — Resolve corpus + answer path (ONE Bash call)

Parse $ARGUMENTS: split on the first |. Left = folder (the SAME folder used with /agy:notebook), right = question. If there is no |, the longest leading token that resolves to an existing directory is the folder and the rest is the question. If the question is empty, ask once and stop.

python - "$FOLDER_OR_SLUG" "$PREGUNTA" <<'PY'
import sys, os, re, glob, hashlib
folder, preg = sys.argv[1], (sys.argv[2] if len(sys.argv) > 2 else "")
def slug(s, n=60):
    return (re.sub(r"[^a-z0-9]+","-", os.path.basename(s.rstrip("/\\")).lower()).strip("-") or "x")[:n]
outdir = os.path.join("docs","agy","notebook", slug(folder))
summ = glob.glob(os.path.join(outdir, "*.resumen.md"))
if not summ:
    print(f"NO_CORPUS outdir={outdir}")           # corpus not built yet
    sys.exit(0)
ans_dir = os.path.join(outdir, "_respuestas"); os.makedirs(ans_dir, exist_ok=True)
qh = hashlib.sha1(preg.encode("utf-8")).hexdigest()[:6]
ans = os.path.join(ans_dir, f"{slug(preg, 40)}-{qh}.md")
print(f"OK SUMMARIES_DIR={os.path.abspath(outdir)} N={len(summ)} WRITE_FILE={os.path.abspath(ans)}")
PY
  • If it prints NO_CORPUS → tell the user to build the corpus first with /agy:notebook "<folder>" | <objective>, and stop.
  • Else capture SUMMARIES_DIR, N (number of summaries) and WRITE_FILE.

Phase 1 — Answer (ONE agy subagent)

Spawn ONE antigravity:agy-rescue subagent in MODE: notebook-ask:

MODE: notebook-ask
CWD: <absolute current working dir>
SUMMARIES_DIR: <SUMMARIES_DIR>
PREGUNTA: <question>
WRITE_FILE: <WRITE_FILE>
USER_TEXT:
(empty)

Phase 2 — Present

Read ONLY <WRITE_FILE> and present the answer verbatim, then note: how many summaries it drew from (N), and the saved path. Do NOT read the original documents or the per-document summaries yourself — agy already grounded the answer in them.

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.
