openstreetmap-statistics: Instructions file for Codex

AGENTS.md

openstreetmap-statistics AGENTS.md is an instructions file for Codex, OpenCode from piebro/openstreetmap-statistics. It costs 5,736 tokens per session, scanned A, original, MIT.

Instructions for creating statistics from OpenStreetMap data, which is open geographic map data edited by a community. They describe the available datasets, their file locations, and how related records such as changesets, notes, and comments connect.

In plain words
What is it for?
Use them to add statistics, query changesets or map notes, analyze comments, and join the project's Parquet datasets by their identifier columns.
Why use it?
They explain the data layout so new analyses use the correct files and joins. This avoids treating separate datasets as if they contained the same records.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is piebro/openstreetmap-statistics's own configuration. It tells Codex and OpenCode how to work on openstreetmap-statistics itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything openstreetmap-statistics configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is FROM '../changeset_data/year=*/month=*/*.parquet'.

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

openstreetmap-statistics AGENTS.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 2mo 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.

Creating New Statistics

The project analyzes OpenStreetMap data through preprocessed parquet files that provide detailed information about changesets, their comments, notes, and note comments.

Available Datasets

The project includes 4 different datasets:

  1. changeset_data - Main dataset containing all changesets with enriched metadata

    • Location: ../changeset_data/year=*/month=*/*.parquet
    • Partitioned by year and month
    • Contains enriched columns like created_by, device_type, imagery_used, etc.

  2. changeset_comments_data - Comments on changesets (changeset discussions)

    • Location: ../changeset_comments_data/*.parquet
    • Not partitioned, stored as flat parquet files
    • Join with changeset_data using changeset_id

  3. notes_data - Notes on the map

    • Location: ../notes_data/*.parquet
    • Not partitioned, stored as flat parquet files
    • Contains information about map notes including their location and status

  4. notes_comments_data - Comments on notes

    • Location: ../notes_comments_data/*.parquet
    • Not partitioned, stored as flat parquet files
    • Join with notes_data using note_id

Dataset Structure

Changeset Data

The changeset dataset is located at ../changeset_data/year=*/month=*/*.parquet and contains the following key columns:

Base Columns

  • changeset_id - ID of the changeset
  • edit_count - Number of edits in the changeset
  • user_name - OSM contributor username
  • year - Year of the changeset
  • month - Month of the changeset

Enriched Columns (added by scripts/changeset_raw_data_to_data.py)

  • created_by - Normalized editing software name
  • device_type - Classification: desktop_editor, mobile_editor, tool, other
  • bot - Boolean indicating if the changeset was made by a bot
  • mid_pos_x, mid_pos_y - Discretized coordinates (0-360, 0-180)
  • imagery_used - Array of imagery sources used
  • hashtags - Array of hashtags from the changeset
  • source - Array of data sources used
  • mobile_os - Mobile OS detection (Android, iOS, or NULL)
  • streetcomplete_quest - Normalized StreetComplete quest type
  • all_tags - Array of all tag prefixes used
  • organised_team - Organised team/corporation affiliation if applicable
  • for_profit - Boolean indicating if the changeset was made by a for-profit organisation

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.
