Tools I Use: OpenCode + OpenRouter + The "Pulse" of the Internet

Mon, 30 Mar 2026 20:09:56 GMT

I’ve been spending a lot of time in the terminal lately. There is something satisfyingly efficient about staying in one window to get work done, rather than tab-switching until my browser looks like a deck of cards.
Recently, I’ve moved my primary AI workflow over to OpenCode.

It’s the open-source answer to things like Claude Code or Cursor, but it gives you back the steering wheel. If you like staying nimble, this is a setup worth looking at.

The Stack: OpenCode & OpenRouter

Most people use these tools with a single API key tied to one company. I prefer OpenRouter.
Think of it as a universal power adapter. Instead of being locked into one provider, you point OpenCode at OpenRouter, and suddenly you can swap "brains" on the fly. Want the logic of Claude 3.5? The speed of Llama? The cost-effectiveness of DeepSeek? You just toggle a setting.

To get them talking, I just add a couple of lines to my .zshrc (or .bashrc for the Linux purists):

Now, when I fire up OpenCode, I’m not just talking to one AI; I’m talking to the best model for the job at that exact moment.

The Secret Sauce: last30days-skill

The biggest hurdle with AI is the "knowledge cutoff." It knows a lot about 2024, but it’s often clueless about what happened on Reddit three hours ago.

I’ve started using a specific skill called last30days, originally built by Matt Van Horn. Even though it was designed for Claude, it works perfectly with OpenCode’s skill architecture. It gives the AI "eyes" on:

Reddit & Hacker News (The "boots on the ground" sentiment)
X (Twitter) (The immediate news cycle)
YouTube (The deep-dive tutorials)
Polymarket (Where people are actually putting their money)

How to add it:

Grab the SKILL.md file from the last30days GitHub.
Drop it into your OpenCode skills folder (usually ~/.config/opencode/skills/).
Restart your session.

Why this matters (even if you don't code)

I know, "OpenCode" sounds like it’s strictly for developers. But once you give an agent the ability to scan real-time sentiment, it becomes a powerful research assistant for almost any industry.

Take a Realtor, for example.
Say a client is nervous about listing their house because of a headline they saw this morning. Instead of digging through news sites, the Realtor can ask OpenCode:
"Use the /last30days skill to check r/Vancouver and X for any shifts in buyer sentiment this week. Also, check Polymarket for the latest odds on the June interest rate cut."

Within seconds, the AI returns a summary:

“Reddit users are reporting increased activity at open houses in North Van over the weekend.”
“Prediction markets have moved from a 20% to a 65% chance of a rate cut.”

That Realtor isn't just reciting a script; they have real-time data to back up their advice.

Final Thoughts

We talk a lot about "Agile" and "Efficiency" at Injinia, but usually, that refers to teams and processes. Sometimes, it’s just about having the right tool in your belt that cuts out the noise.
OpenCode paired with OpenRouter gives you the flexibility; the last30days skill gives you the context. If you're tired of AI that feels "stuck in last year," give this a shot.
What are you using to stay on top of real-time info? Drop me a note, I’d love to hear about it.

And now for something completely different...

DIY Hammock

Starting a new DIY project always piques my interest as a coder - it's like tackling a new programming challenge. My latest endeavor was creating an 11-foot netless gathered-end hammock from scratch, optimizing it with some custom design tweaks. To get a solid foundation, I did a deep dive into over 50 hammock-related patents one afternoon, essentially auditing the codebase of prior art. So many fascinating implementations and experimental features to explore!

From there, I immersed myself in the hammockforums.net community, the open-source knowledge-base for this niche. I spent hours trawling through threads, extracting insights from veteran hammockers on best practices, anti-patterns to avoid, and new feature enhancements to consider. Definitely some gems in there amongst the version history!

With a solid architecture mapped out from my research, I was ready to start prototyping my optimized hammock build. Iterative development and bug testing in the real-world would commence.

Gathering Materials

For materials, I looked back at what I had used for my previous hammock prototype - the HyperD XL fabric and thread from ripstopbytheroll.com, some miscellaneous cordage from Amazon.ca, and a few components I already had on hand. Initially, I had planned to source everything directly from Dutchweargear.com for a streamlined supply chain. But after factoring in shipping fees and currency exchange rates, I decided to see if there was a Canadian supplier for the components.

After some research, I discovered a promising Canadian vendor - hofmanoutdoorgearsupply.ca. They stock a wide range of hammock, camping and MYOG (make your own gear) supplies. While they didn't carry the exact HyperD XL fabric, they did offer Hexon W from Dutchwear, which seemed to be an optimized fabric designed specifically for hammocks.

My hammock "tech stack"

With my updated supply chain and tech stack selected, I could proceed to the next phase of building and integration...

Crafting the Hammock Body

With the fabric acquired, I carefully measured and cut it to 11'5" including seam allowances to achieve the desired 11' finished length. Applying tips that I learned after my last build, I marked fold-to guides along all edges - 1" rolled hems on the ends and 1/2" hems on the sides.

Knotty Mod Prep
At 2' and 4.5' from the foot end on each side, I marked buttonhole reinforcements where the shock cords would anchor for the Knotty Mod, deviating slightly from standard implementations.

Gear Attachment Points
The centers of each end were marked for larger buttonholes to attach a structural ridgeline internally and grosgrain webbing loops to accommodate gear hooks.

Sewing Process
Swapping between machine setups, feet, retensioning, and replacing a couple bent needles, we finally mastered the automatic buttonhole feature to install all 6 reinforcements. A team effort with my wife and daughter! Note: Make the ridgeline hole 3/4" not 1/4" next time.

Hemming went smoothly once edges were folded and pinned to ensure everything was aligned and to position the buttonholes correctly. The ends required sewing in the grosgrain loops, using some surplus 3/4" military webbing I had lying around (500' for some reason?), instead of standard 1/2" for added durability. The triple parallel stitching for the end channel was hard to not fully OCD over. While not required for whipped ends, I included a 1" channel to allow experimenting with different suspension systems later on.

Once it was all hemmed, I began adding the tie out points and a few attachment point loops along the edges using 3" sections of the 1/2" grosgrain. I pulled some 1/8" shock cord through the channel created in each side to form the Knotty Mod. The shock cord was anchored to a grosgrain loop at the foot end, and to a Line Lock sewn into another grosgrain loop near the middle of the hammock. I added one to each side to test out options for different diagonal laying positions.

Ridgeline and Suspension

Suspension
Having tried a number of different suspensions, I've found I like the ones that are simple, fully adjustable, don't take up a lot of room, require as little "hardware" as possible, and are quick to set up and take down. Most suspensions, I've played with, require at least 2 connect/disconnect points on each end, and you wind up with multiple bits that need to be stored or put together each time. For this hammock, I was looking for something as simple as possible. Originally I was going to go with beetle buckles and a Dutch clip with a tree strap and continuous loop. However, with buying things from Hofman instead of Dutchwear and wanting to keep costs down I went with cinch buckles, continuous loops, tree straps, and a soft shackle.

Feeding the continuous loop attached to the cinch buckle through the end channel made for a simple connection to the hammock.

The cinch buckle makes it very easy to adjust the suspension, and is lite and small. To solve for all of the connecting and disconnecting every time, as well as to speed things up I leave the tree strap connected to the cinch buckle all the time. Instead of looping the end of the line through the loop at the other end of the tree strap, I simply use a soft shackle to connect the two. This seems quite simple and fast for me now, and enables a cleaner setup, without straps or hammock ending up on the ground. Great for setting up in places where there is mud, wet sand, thorn bushes, or anything else you don't want to have to deal with cleaning up.

Ridgeline
I've been using various types of ridgelines for quite a while. Before I knew what they were or why they were, I added one on to my first hammock as it made setup a lot simpler and more consistent. After reading of the different types, pros and cons for each, I tested out a number of styles, and, after much experimentation, found that a fixed structural ridgeline worked best for me.

I "discovered" Amsteel rope a while ago, and it is exrtemly useful for lightweight hammock setups. I've made a number of ridgelines with it, so set about making one for the new hammock. I measured the final length of the hammock after gatheirng the ends, and made a ridgeline with locked brummel loops at each end. For my liking and after a few experimental naps in the hammock my ridgeline is 85.8".

To connect the ridgeline to the continuous loop, I used a lark's head from the end of the ridgeline, through the buttonhole in the center of the hammock end channel to connect it to the continuous loop. The buttonhole I had sewn was only 1/4", and should have been larger. It was quite a chore getting it connected. For the other end I used a small soft shackle so that I can disconnect to add things like permanent ridgeline organizers or things of that sort.

Fashioning the Bishop Bag

No hammock is complete without a convenient storage solution, so I whipped up a bishop bag to hold it all together. A bishop bag is perfect for stowing away my hammock and makes it easy to keep everything off the ground and accessible. I made it large enough to store the hammock, suspension, an underquilt and a bugnet. (more on these sometime later).

The Final Touches

n old all-in-one hammock I have had 4 small pockets, one on each side at each end, about 1' from each end. I found these very useful for keeping things close at hand, without having them wind up in the bottom of the hammock, and without having them hanging on the ridgeline. I had some fabric left over, and some clips intended for tarp tie outs, so I made a couple of pockets. The clips allow for them to be positioned wherever they are needed.

With the last bit of fabric I made a simple ridgeline bag as well using the pack clips.

Enjoying the results

Since the weather outside is typical Alberta spring (i.e. 10 inches of snow and -14 C) I had to setup a tensahedron stand made out of old army surplus antenna mast poles in the basement. (I'll post some info about that, as well as some plans for a smaller, packable aluminum one soon!)

AI generated test example: PyAutoGUI

Sat, 03 Jun 2023 07:00:00 GMT

After playing with the code for the last post a bit, a colleague asked how hard it would be to do the same with a random python library. A quick search turned up PyAutoGUI, which seems ok.

Popping open the last chat that was used to generate the code for the previous post, and simply asking it to "Ok, now generate a python script to use the gherkin test case. Use the pyautogui library."

This generates:

Hmm, now I just need to build a test library that will test AI generated tests.....

Enhancing Traditional GUI Testing with AI

Thu, 01 Jun 2023 07:00:00 GMT

In the fast-paced world of software development, functional GUI testing plays a critical role in ensuring seamless user experiences. While traditional GUI testing approaches have been effective, the emergence of Artificial Intelligence (AI) has brought a new wave of possibilities to enhance and optimize the testing process. How can AI elevate traditional GUI testing? What are the benefits of utilizing test cases generated by AI. I'll give an example prompt and demonstrate how an AI can generate test cases to streamline the testing process.

The Power of AI
Artificial Intelligence introduces a range of advancements that augment traditional GUI testing, enabling more efficient and effective processes. Rather than replacing traditional methods, AI serves as a valuable ally, complementing and enhancing existing practices. AI can leverage Natural Language Processing (NLP) algorithms to generate Gherkin-style test cases, further streamlining the testing process.

To demonstrate the power of AI, let's consider an example prompt:
"Write gherkin test cases to validate the login functionality."

The prompt produces structured test cases that describe the login functionality. Here's an example of test cases generated by the AI:

AI-powered Execution and Analysis
With these test cases in hand, an existing test library like watir can be integrated seamlessly. With a few more prompts like, "Now generate the ruby code to run this test using the watir library. Use the page object pattern, and separate the code into the correct files. Use a test_params.yaml file to store the variables like urls, usernames, passwords, etc."

Here is what we get:

It even generated some helpful instructions:

Conclusion
While there is still some setup and configuration to do, we can see that AI brings a wealth of opportunities to enhance traditional GUI testing practices. By generating some of the basic test cases we can focus effort on doing the non-standard tests, poking around where we know the bugs hide.

Integrating AI with existing GUI testing libraries allows for automated uses of the generated test cases.
Embracing AI in GUI testing is a powerful tool in our QA bag of tricks. So, let's embrace the potential of AI and unlock a new era of GUI testing!
