pipelinewise AGENTS.md

pipelinewise AGENTS.md is an instructions file for Codex, OpenCode from transferwise/pipelinewise. It costs 1,317 tokens per session, scanned A, original, Apache-2.0.

A guide for contributors to PipelineWise, a Python framework that moves data between systems using Singer data pipelines.

In plain words
What is it for?
Use it when changing PipelineWise code, Singer connectors, documentation, migrations, command-line behavior, or unit and end-to-end tests.
Why use it?
It explains the project’s architecture, scoped instructions, data-transfer modes, and which tests and documents apply to each area.

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

pipelinewise 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 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.

Scope

PipelineWise is a Python 3.12 Singer ELT framework. Write for senior engineers; prioritize operational precision, edge cases, and rationale. Read each relevant guide:

  • pipelinewise/AGENTS.md: orchestration, FastSync, backend migrations, data-diff.
  • singer-connectors/AGENTS.md: vendored taps and targets.
  • tests/AGENTS.md: unit tests and suite boundaries.
  • tests/end_to_end/AGENTS.md: databases, connectors, E2E, dev-project/.
  • docs/AGENTS.md: documentation.

Scoped guidance adds to this file; explicit user instructions win. Each CLAUDE.md symlinks to its adjacent AGENTS.md; edit the latter and preserve the link.

Architecture

  • Singer JSON flows as tap | [transform-field] | [mbuffer] | target; YAML becomes generated config, state, and catalog JSON.
  • pipelinewise/cli/__init__.py defines argparse and dispatches to PipelineWise. Canonical fast_sync and import_config retain deprecated aliases sync_tables and import.
  • FastSync is a native full/filtered bulk-transfer optimization, not a replication method. Singer handles INCREMENTAL/LOG_BASED and FULL_TABLE streams not selected for FastSync.

Environment

  • Prefer the dev-project Docker stack; its Linux runtime best matches production. Use the host only to manage Docker or when a check cannot run in the container, and report the compatibility gap.
  • The repo is mounted at /opt/pipelinewise in the pipelinewise container. PIPELINEWISE_HOME environments live under dev-project/.virtualenvs/ and are on PATH.
  • make pipelinewise installs the editable root plus test extras. Connector runtimes use .virtualenvs/<name>/; connector Makefiles may use venv/. Never mix host, container, root, runtime-connector, or connector-test interpreters, and never use repository .venv/.

Validation

For implementation changes, run these root gates verbatim and in order, preferably in the ready container:

ruff check pipelinewise tests
pylint pipelinewise tests
flake8 pipelinewise --count --select=E9,F63,F7,F82 --show-source --statistics
flake8 pipelinewise --count --max-complexity=15 --max-line-length=120 --statistics
pytest --cov=pipelinewise --cov-fail-under=77 -v tests/units

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.
