comprehensiveness-over-simplification

comprehensiveness-over-simplification is a cursor rule for Cursor from arango-solutions/arango-sparql-py. It costs 487 tokens per session, scanned A, original, MIT.

A set of rules for building production software with complete handling for errors, unusual inputs, security, testing, configuration, monitoring, and documentation.

In plain words
What is it for?
Use it as a checklist when implementing features, reviewing code, designing tests, handling failures, adding observability, or preparing software for different environments.
Why use it?
It reduces the risk of shipping code that works only in the usual case but fails silently or dangerously in real environments.

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

comprehensiveness-over-simplification 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 7d 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.

Comprehensiveness Over Simplification

"If a feature ships incomplete, it didn't ship—it leaked."

You are building production systems. Simplification is the enemy of completeness.

Completeness Dimensions

Every piece of work must address ALL of the following. Skipping any is a defect.

Error Handling

  • No swallowed errors — every catch/if err != nil must DO something
  • Descriptive messages — WHAT failed, WITH WHAT input, WHY
  • Context wrapping — fmt.Errorf("loading config: %w", err)
  • Graceful degradation over crashing

Edge Cases

Every function must handle: empty/nil inputs, boundary values, invalid inputs, unicode/special chars, concurrent access.

Configuration Over Hardcoding

If a value could EVER differ across dev/staging/prod, it must be configurable.

Test Completeness

Cover: happy path, error paths, edge cases, concurrency, regressions.

Observability

Structured logging (not fmt.Println), metrics, tracing, health checks, alertable events.

Security

Input validation at boundaries, no secrets in code/logs, auth/authz checks, least privilege.

Documentation

Public function docstrings, README updates, API docs with examples, architecture notes for non-obvious decisions.

UI/UX (Frontend)

Handle: loading, error, empty, success states. Accessibility (ARIA, keyboard nav). Responsive design.

Data Integrity

Validate at boundaries, database constraints, transaction safety, idempotency.

Performance

Pagination, caching, lazy loading, indexing, connection pooling.

Anti-Patterns (NEVER Do)

Anti-Pattern Consequence
Happy Path Only Production incidents
"We'll Add That Later" "Later" never comes
Empty Catch Blocks Hidden failures
Magic Numbers Unmaintainable code
Copy-Paste Coding Divergent behavior over time
Console.log Debugging Noise in production logs

The Mantra

"Complete is better than clever. Robust is better than fast. Production-ready is the only ready."

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.

comprehensiveness-over-simplification is a cursor rule published in the GitHub repository arango-solutions/arango-sparql-py (2 stars, last pushed today), licensed MIT. It adds 487 tokens to every session, about $0.0024 per session on Opus 5. 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 2026-08-31.
