incremental-over-atomic

incremental-over-atomic is a cursor rule for Cursor from arango-solutions/arango-sparql-py. It costs 390 tokens per session, scanned A, original, MIT.

A rule for making changes in small, working increments instead of one large rewrite. Each step should compile, pass tests, and remain usable.

In plain words
What is it for?
Use it to guide refactoring and feature work through independently testable steps, such as adding new code, migrating callers, and removing old code gradually.
Why use it?
Small verified changes are easier to review, undo, and troubleshoot when something goes wrong.

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

incremental-over-atomic 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 4d 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.

What it actually says

Incremental Over Atomic

"Small steps that individually work > Large steps that eventually work."

Big-bang changes are high-risk gambles. Incremental changes are safe, reviewable, and reversible.

Instead of Big Bang → Incremental Slices

Big Bang Incremental
Refactor entire module at once Refactor one function, verify, commit, repeat
Add feature + tests + docs in one PR Types first → logic → tests → docs
Replace old system with new Run both in parallel, migrate gradually, remove old

Each Increment Must Be

  • Verifiable — can be tested independently
  • Reversible — can be rolled back without affecting other changes
  • Reviewable — small enough to understand in < 5 minutes
  • Deployable — doesn't break the build in isolation

If an increment takes more than 30 minutes, slice smaller.

The Working State Rule

At every checkpoint, the codebase MUST: compile, pass tests, be functional.

Refactoring Pattern

# GOOD: Incremental
1. Add new function alongside old → verify (commit)
2. Migrate one caller → verify (commit)
3. Repeat until all callers migrated
4. Remove old function (commit)

Anti-Pattern Detector

  • Changing more than 5 files at once → Slice smaller
  • Working 1+ hour without a commit → Checkpoint now
  • Unable to describe the change in one sentence → It's too big
  • Afraid to run tests because "it's not done yet" → You've gone too far

Small steps. Verify each one. Never break the build.

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.
