update-examples

Project rules for updating the pytidb Python dependency in every example application and checking that each example still runs.

In plain words
What is it for?
Use them when a new pytidb version is released. They cover finding examples, updating requirement files, creating virtual environments, installing packages, and running entry points.
Why use it?
They prevent examples from using inconsistent or outdated dependency versions. Running each example exposes broken installation or compatibility problems.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 206 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

update-examples 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 yesterday.

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

Update the pytidb dependency in all example projects (e.g., examples/auto_embedding/reqs.txt) and verify that they work with the latest version.

Steps

  1. List all examples
  2. Using todo_write tool to add each example to the ToDo list.
  3. Process each example as following steps one by one.
    1. Check the latest pytidb version in pyproject.toml.

    2. Update the reqs.txt files accordingly.

    3. Create a virtual environment (If not exists):

      python -m venv .venv
      source .venv/bin/activate
      
    4. Install dependencies:

      pip install -q -r reqs.txt
      
    5. Run the example entry point (python main.py or streamlit run app.py) to confirm functionality.

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.

update-examples is a cursor rule published in the GitHub repository pingcap/pytidb (33 stars, last pushed 5mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 206 tokens. 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.
