| name | retentioneering-contributing |
| description | Help the user turn their Retentioneering ideas, friction reports, bug findings, or feature needs into high-quality upstream contributions: from capturing and validating the idea, through minimal reproductions and issue drafts, to preparing, testing, and submitting a pull request that follows this repository's conventions. Use when the user says they found a bug, wants a feature, wrote a workaround worth upstreaming, or asks how to contribute, open an issue, or make a PR to retentioneering-tools.
|
| license | Apache-2.0 |
| compatibility | Requires a git checkout of retentioneering-tools, Python >= 3.11 with uv, and Node.js only when JS/widget code is touched. The gh CLI is optional but recommended for PR submission.

Contributing to retentioneering-tools
Objective
Convert a user's observation — a bug, a paper cut, a missing capability, a workaround
they keep re-writing — into the smallest upstream change that would have prevented it,
packaged so maintainers can accept it quickly.
Bundled references
| File | Read it when |
|---|
references/repo-conventions.md | before touching code — build/test/docs commands, architecture rules, naming, sync obligations |
references/proposal-templates.md | when drafting — issue/feature/PR templates with worked examples |
The full route: idea → merged PR
Stage 1 — Capture the observation properly (do this even for "small" ideas)
Record four things while they are fresh:
- Expectation — what the user believed would happen (quote the docstring/docs page
that created the expectation, if any).
- Reality — what actually happened (exact error text or wrong output).
- Cost — time lost, wrong conclusion nearly shipped, workaround written.
- Environment —
retentioneering.__version__, Python, OS, install source
(pip wheel vs source checkout).
Field lesson: reports formatted as expectation/reality/cost/repro get acted on;
"X is broken" reports stall.
Stage 2 — Validate against the CURRENT version
Many pain points are already fixed on v5-migration — verify before drafting:
git log --oneline -30 and CHANGELOG.md — search keywords from the observation.- Search existing issues/PRs:
gh issue list --search "<keywords>", gh pr list ....
- Reproduce on the current checkout (see Stage 3). If it no longer reproduces, the
contribution may become a docs clarification or a regression test instead — both welcome.
Stage 3 — Minimal reproduction (the heart of a bug report)
Build the smallest toy that shows the gap, e.g.:
import pandas as pd
from retentioneering import Eventstream
df = pd.DataFrame({"user_id": ["u1","u1","u2"], "event": ["a","b","a"],
"timestamp": pd.date_range("2026-01-01", periods=3, freq="1min")})
Rules: synthetic data only (never the user's real log); deterministic (fixed frames, no
randomness without seed); one behavior per repro; assert the expectation so the repro
doubles as a failing test.
Stage 4 — Choose the contribution shape
| Situation | Shape |
|---|
| Clear defect with repro | Issue with repro; PR with fix + regression test if user wants to go further |
| Surprising-but-documented behavior | Docs PR (docstring is the source of truth — site pages regenerate from it) |
| Missing capability | Feature issue: use-case first, proposed signature second, evidence third (see templates) |
| Repeated workaround in user's code | Extract as proposed API: show the workaround, its cost, the proposed call replacing it |
| Wrong-conclusion trap (library was silent) | Frame as "missing signal": what the library knew and did not surface; propose the warning/field |
For API proposals, the accepted framing (from templates): problem → evidence of frequency
→ proposed signature → semantics incl. edge cases → acceptance criteria → migration notes.
Stage 5 — Implement (when making a PR, not just an issue)
Read references/repo-conventions.md first. Non-negotiables:
- Fork or branch from
master-tracking v5-migration; one logical change per PR.
make install-dev — installs deps (uv sync + npm install) and wires the git hook
(a one-time-per-clone step) so commits are auto-checked; skip it and commits bypass the hooks
locally and CI's lint job flags the formatting on your PR. Add make build only when
touching widgets/JS.- Follow naming conventions (ADR-0008):
path_col/event_col/timestamp_col/session_col,
start_anchor/end_anchor, verb-first processors, noun widgets, <widget>_data twins.
- All DuckDB execution goes through the unified query engine (L1) — no ad-hoc
duckdb.sql with replacement-scan idioms (superseded ADR-0002).
- Add/extend tests next to the code area (
tests/...); a bug fix MUST include the
failing-before test from Stage 3.
- Keep the loud-and-helpful error pattern: errors that list valid values/keys are the
house style; silent degradation (dropped rows, empty results without a signal) is an
auto-reject.
- Sync obligations when renaming/changing API: MCP tool layer mirrors Eventstream
method names; JS metric editor consumes the Python metric schema; docstrings feed the
docs site — update all in the same PR (
uv run python docs/scripts/render_pages.py).
Stage 6 — Pre-flight and submit
uv run pre-commit run --all-files
uv run pytest tests/ -v
uv run python docs/scripts/render_pages.py
Commit style: imperative, scoped, explaining WHY when non-obvious (see git log for the
house voice). Update CHANGELOG.md under the unreleased/current section for
user-visible changes.
Submit:
git push -u origin <branch>
gh pr create --title "<imperative summary>" --body-file pr_body.md
PR body (template in references/proposal-templates.md): what & why → linked issue →
repro/before-after → tests added → sync checklist (docs/MCP/JS if applicable) →
breaking-change note. CI must pass: lint + test (3.11/3.12/3.13). master is
PR-only; merging does not release (releases are tag-driven by maintainers).
Stage 7 — Follow through
Respond to review within the PR (avoid force-push after review starts; append commits).
If maintainers ask for direction changes, update the issue first, then the code — the
issue is the contract.
Portfolio mode: many observations at once
When the user accumulated a batch (e.g., a journal of friction from a project):
deduplicate → verify each against current version (Stage 2) → rank by
(frequency × silent-failure risk) → file the top 3–5 as separate issues with repros →
offer one PR for the cheapest verified fix to build credibility, referencing the issues
for the rest. Do not open one mega-issue.
