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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00801 | $0.00801 |
| Opus 5.5 | $0.00320 | $0.00320 |
| Sonnet 5.5 | $0.00160 | $0.00160 |
| Haiku 4.5 | $0.00080 | $0.00080 |
Grade A, and why
pixeltable-skill GEMINI.md 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 3d 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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Pixeltable extension
Pixeltable is an open-source Python library and declarative data backend for multimodal AI
(images, video, audio, documents, text). One application file (app.py) declares tables and
HTTP routes. Create tables with pxt schema update. Serve with pxt service update.
- Docs: https://docs.pixeltable.com (agent index: https://docs.pixeltable.com/llms.txt)
- Repo: https://github.com/pixeltable/pixeltable
- Install:
pip install 'pixeltable[serve]'(Python 3.11+), import asimport pixeltable as pxt
Skill (authoritative)
This extension bundles the Pixeltable skill at skills/pixeltable-skill/SKILL.md (and
skills/pixeltable-skill/references/). Gemini CLI loads skills/*/SKILL.md automatically.
Follow that skill for the application file, CLI, providers, serving, and anti-patterns.
Do not copy those files into this context, and do not invent a second apply path.
Start from pxt init then pxt service example --out app.py (or pxt schema example --brief).
Then pxt schema update app.py my_app. Agent-facing pxt service update needs -f.
MCP servers in this extension
pixeltable-cloud (hosted Streamable HTTP, https://www.pixeltable.com/mcp/cloud).
For Pixeltable Cloud users. Sign-in is OAuth in the browser (WorkOS AuthKit); Gemini CLI
handles the tokens. No API key belongs in this extension. Run /mcp auth pixeltable-cloud
if tools are not listed. The server acts on the organization chosen at sign-in.
It is not read-only. It both reads and writes:
- Reads: databases, services, catalog entries, table schemas, up to 25 rows per call, recent logs.
- Writes:
start_databaseacts immediately.stop_database,restart_service, andset_secretreturn a preview first. Show the preview to the user and call again withconfirm: trueonly after they agree.
It deletes nothing, does not deploy, and does not run arbitrary queries. Use the pxt CLI to
ship: pxt db update, pxt schema update, pxt service update. For a read-only connection,
the user can change the URL to https://www.pixeltable.com/mcp/cloud?read_only=true;
?db=<name> limits it to one database.
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.

pixeltable-skill GEMINI.md is an instructions file published in the GitHub repository pixeltable/pixeltable-skill (6 stars, last pushed yesterday), licensed Apache-2.0. It adds 801 tokens to every session, about $0.0032 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-22.
