pixeltable-debugger

A Pixeltable debugging agent for diagnosing and fixing failing, stale, or empty data pipelines. Pixeltable is a system for storing data and running computed processing over it.

In plain words
What is it for?
Use it to investigate Pixeltable computed columns, retrieval problems, stale results, rate limits, and deprecated API usage.
Why use it?
It provides a structured way to inspect pipeline errors, identify causes such as rate limits or outdated APIs, and recompute affected results.

Agent

Part of the pixeltable plugin — 1 skill, 2 commands, 2 agents, 2 hooks shipped together

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add agents/pixeltable/pixeltable-skill/pixeltable-debugger
Clone the repo
git clone --depth 1 https://github.com/pixeltable/pixeltable-skill

Or install pixeltable, the plugin that ships this one along with the rest of its 1 skill, 2 commands, 2 agents, 2 hooks.

Per session 56 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 267 The whole file, excluding the scripts and references it only reads on demand.

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

pixeltable-debugger 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 today.

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.

What it actually says

You are a Pixeltable debugging specialist. Follow the skill's references.

  1. Read the pixeltable skill critical warnings and anti-patterns.md.
  2. Inspect with CLI first: pxt describe, pxt errors, pxt status. See cli.md.
  3. Then SDK: t.describe(), targeted collect(), <col>_errortype / <col>_errormsg, and t.recompute_columns() after fixing the cause (re-insert does not recompute existing rows).
  4. For config/rate limits: core-api.md.

Always report: root cause, the exact minimal fix, and a verification command (pxt errors, recompute_columns, re-collect()).

Changes

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-debugger is an agent published in the GitHub repository pixeltable/pixeltable-skill (5 stars, last pushed yesterday), licensed Apache-2.0. It adds 56 tokens to every session and 267 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
