UX Pilot's subscription defaults and refund process
I recently signed up for UX Pilot and was automatically placed on an annual plan, rather than the monthly plan I intended. When I requested a refund, I’ve been waiting 20 days with only vague updates from support.
Now they are proposing additional fees for an issue caused by their own default settings. This seems like a dark-pattern subscription tactic, and it’s frustrating to see how slow and unclear their refund process is.
Has anyone else run into similar issues with UX Pilot or comparable SaaS services? Curious how others handle these kinds of subscription pitfalls.

Ask HN: Why don't buildings have dry warm up rooms for your laptop in winter?
In winter, a laptop can get cold enough during a long walk or commute that it picks up moisture as soon as you enter a warm building. Powering on a damp laptop can cause damage, so a simple solution came to mind.
Public buildings like malls or libraries could offer a small dry warm up room where people take their cold laptops for ten to twenty minutes. The room would be warm with low humidity so the device can reach indoor temperature without collecting moisture.
Would you use these dry warm up rooms to protect your laptop from water damage during winter?

Show HN: Dependency-aware context management for LLM coding workflows
If you are using Cursor or Claude Code, you must try this open-source tool—it will save you MONEY and TIME.
If you're building complex projects and your context keeps getting larger, losing track of what's current and what's outdated, you're going to love this.
THE PROBLEM:
When using LLMs to build products, we generate tons of context—requirements, specs, design docs. But then:
Can't tell which document is the latest/authoritative
No traceability between layers (business → system → code → tests)
Upstream requirements change, downstream doesn't get updated
Your LLM uses STALE context → incorrect output
Burning tokens on entire files when you need specific snippets
THE SOLUTION: contextgit
A tool built specifically for LLMs to trace context efficiently.Instead of dumping entire files into context, contextgit lets your AI navigate requirements like a graph database—extracting only what's needed.
Extract ONLY relevant snippets (save tokens = save money)
Track relationships: business → system → architecture → code → test
Auto-detect staleness via checksums
Full JSON output for LLM integration
See project health: orphaned requirements, broken links, stale items
KEY USE CASES:
LLM-driven development: AI asks for requirements by ID, not entire docs
Massive token savings: Feed 20 lines instead of 5,000
Auto-detect stale context: LLMs know when requirements are outdated
CI integration: Block PRs with stale requirements
REAL IMPACT:
Instead of: LLM reads 5000-line docs → wastes tokensNow: contextgit extract SR-010 → 20 lines → saves hundreds in API costs
If you find this useful, please star the repo!
100% open source (MIT), production-ready (v1.0.1). This is the missing piece for LLM-driven development.
