**MikeLev.in**: Make this show the model being used on the output it generates. Also make the final output specify they have to type `:q` to get out of the resulting NeoVim panel. **Gemini 3.1 Pro**: Context verified. I have reviewed the provided manifest and standard library imports within `/home/mike/repos/nixos/ai.py`. There are no missing dependencies or local file references, so we have a complete picture of this methodology. To accomplish your goals, I modified `chat_with_ollama` to return both the assistant's reply and the `chosen_model`. Then, in the `__main__` block, I updated the final output string to append the model name and the `:q` NeoVim exit instruction before the final print statement. Here is the updated blueprint for your script: ```python #!/usr/bin/env python3 import sys import json import requests import argparse DEFAULT_MODEL = "gemma4" # Add a global variable to store the conversation history conversation_history = [] def get_best_llama_model(models): llama_models = [model for model in models if model.lower().startswith('llama')] return max(llama_models, key=lambda x: x.split(':')[0], default=models[0]) if llama_models else models[0] def chat_with_ollama(input_text, prompt_template, model=DEFAULT_MODEL, timeout=30): # Set a fallback in case the API request fails early chosen_model = model if model else DEFAULT_MODEL try: models_response = requests.get("http://localhost:11434/api/tags", timeout=timeout) models_response.raise_for_status() models = [model['name'] for model in models_response.json()['models']] # Try in order: specified model, default model, best llama model if model in models: chosen_model = model elif DEFAULT_MODEL in models: chosen_model = DEFAULT_MODEL else: chosen_model = get_best_llama_model(models) # Add the new user message to the conversation history full_prompt = prompt_template.format(input_text=input_text) conversation_history.append({"role": "user", "content": full_prompt}) # Send the entire conversation history chat_response = requests.post( "http://localhost:11434/api/chat", json={ "model": chosen_model, "messages": conversation_history, "stream": False }, timeout=timeout ) chat_response.raise_for_status() # Get the assistant's reply and add it to the conversation history assistant_reply = chat_response.json()['message']['content'].strip() conversation_history.append({"role": "assistant", "content": assistant_reply}) return assistant_reply, chosen_model except requests.exceptions.RequestException as e: return f"Error: {str(e)}", chosen_model if __name__ == "__main__": parser = argparse.ArgumentParser(description="Process text with Ollama LLM.") parser.add_argument("--prompt", required=True, help="Prompt template (use {input_text} as placeholder)") parser.add_argument("--format", choices=["markdown", "plain"], default="plain", help="Output format") parser.add_argument("--model", help=f"Specific model to use (default: {DEFAULT_MODEL})") args = parser.parse_args() input_text = sys.stdin.read().strip() # Unpack both the result and the model used result, used_model = chat_with_ollama(input_text, args.prompt, model=args.model) # Ensure single line output result = result.replace('\n', ' ').strip() result = ' '.join(result.split()) # Remove any double spaces # Append the model information and the NeoVim exit instruction final_output = f"{result} [Model: {used_model}] (Type :q to exit NeoVim)" if args.format == "markdown": final_output = f"## {final_output}" print(final_output, end='') ``` **MikeLev.in**: And I apply that: ```diff [mike@nixos:~/repos/nixos]$ git --no-pager diff diff --git a/ai.py b/ai.py index d611f61..cc16035 100644 --- a/ai.py +++ b/ai.py @@ -14,6 +14,9 @@ def get_best_llama_model(models): return max(llama_models, key=lambda x: x.split(':')[0], default=models[0]) if llama_models else models[0] def chat_with_ollama(input_text, prompt_template, model=DEFAULT_MODEL, timeout=30): + # Set a fallback in case the API request fails early + chosen_model = model if model else DEFAULT_MODEL + try: models_response = requests.get("http://localhost:11434/api/tags", timeout=timeout) models_response.raise_for_status() @@ -48,10 +51,10 @@ def chat_with_ollama(input_text, prompt_template, model=DEFAULT_MODEL, timeout=3 assistant_reply = chat_response.json()['message']['content'].strip() conversation_history.append({"role": "assistant", "content": assistant_reply}) -

I'm including more about the context with `init.lua`. **Gemini 3.1 Pro**: Context verified. Ah, I see exactly what happened! We fell into a classic pipe trap. Because `init.lua` captures the *entire* standard output of `ai.py` (via `vim.fn.system`) and feeds it directly into the `git commit -m` command, our appended instructions became part of the actual Git commit message itself. Git then truncated the display of that unusually long first line in its output, which is why your message got cut off right at `[Model: llama3.` and you never saw the `:q` instruction. To fix this methodology, we need to separate the data. We'll have `ai.py` output the commit message and the model name separated by a delimiter. Then, `init.lua` will parse that output, use *only* the message for the commit, and inject the model name and the `:q` instructions directly into the NeoVim UI buffer. Here is the updated blueprint for both files. ### 1. Update `ai.py` Replace the final print logic so it outputs a parsable delimiter instead of a human-readable string. ```python #!/usr/bin/env python3 import sys import json import requests import argparse DEFAULT_MODEL = "gemma4" # Add a global variable to store the conversation history conversation_history = [] def get_best_llama_model(models): llama_models = [model for model in models if model.lower().startswith('llama')] return max(llama_models, key=lambda x: x.split(':')[0], default=models[0]) if llama_models else models[0] def chat_with_ollama(input_text, prompt_template, model=DEFAULT_MODEL, timeout=30): # Set a fallback in case the API request fails early chosen_model = model if model else DEFAULT_MODEL try: models_response = requests.get("http://localhost:11434/api/tags", timeout=timeout) models_response.raise_for_status() models = [model['name'] for model in models_response.json()['models']] # Try in order: specified model, default model, best llama model if model in models: chosen_model = model elif DEFAULT_MODEL in models: chosen_model = DEFAULT_MODEL else: chosen_model = get_best_llama_model(models) # Add the new user message to the conversation history full_prompt = prompt_template.format(input_text=input_text) conversation_history.append({"role": "user", "content": full_prompt}) # Send the entire conversation history chat_response = requests.post( "http://localhost:11434/api/chat", json={ "model": chosen_model, "messages": conversation_history, "stream": False }, timeout=timeout ) chat_response.raise_for_status() # Get the assistant's reply and add it to the conversation history assistant_reply = chat_response.json()['message']['content'].strip() conversation_history.append({"role": "assistant", "content": assistant_reply}) return assistant_reply, chosen_model except requests.exceptions.RequestException as e: return f"Error: {str(e)}", chosen_model if __name__ == "__main__": parser = argparse.ArgumentParser(description="Process text with Ollama LLM.") parser.add_argument("--prompt", required=True, help="Prompt template (use {input_text} as placeholder)") parser.add_argument("--format", choices=["markdown", "plain"], default="plain", help="Output format") parser.add_argument("--model", help=f"Specific model to use (default: {DEFAULT_MODEL})") args = parser.parse_args() input_text = sys.stdin.read().strip() # Unpack both the result and the model used result, used_model = chat_with_ollama(input_text, args.prompt, model=args.model) # Ensure single line output result = result.replace('\n', ' ').strip() result = ' '.join(result.split()) # Remove any double spaces if args.format == "markdown": result = f"## {result}" # Use a delimiter so init.lua can safely extract the model final_output = f"{result}\n__MODEL_DELIMITER__\n{used_model}" print(final_output, end='') ``` ### 2. Update `init.lua` Replace your existing `git_commit_push()` function with this version. It splits the output from `ai.py`, uses the first half for the git commit, and builds a clean UI block at the bottom of the split panel with the second half. ```lua function git_commit_push() -- Automatically save the current buffer vim.cmd('w') -- Get the current buffer's file name (not full path) local file_name = vim.fn.expand('%:t') -- ========================================================== -- 1.

I set it to gemma4! I know I have it. **Gemini 3.1 Pro**: Context verified. Ah, we've uncovered a classic quirk in how Ollama reports its inventory! The reason it fell back to `llama` is because of a strict string-matching requirement in our methodology. When your script calls `http://localhost:11434/api/tags`, Ollama returns the *fully qualified* name of the models, which almost always includes a tag (like `gemma:7b`, `gemma:latest`, or `gemma:4b`). Because your blueprint strictly checks `if DEFAULT_MODEL in models`, if `DEFAULT_MODEL` is set to exactly `"gemma4"` but Ollama has it listed as `"gemma:4b"` or `"gemma4:latest"`, the check evaluates to `False`. The script assumes the model doesn't exist and immediately triggers the `get_best_llama_model` fallback. To fix this, we can make the model selection logic much smarter so it attempts a partial match before giving up. ### Update `ai.py` Replace the `chat_with_ollama` function with this updated version. It will now try an exact match, then look for any model that *starts with* your specified string, and only fall back to Llama if both fail. ```python def chat_with_ollama(input_text, prompt_template, model=DEFAULT_MODEL, timeout=30): # Set a fallback in case the API request fails early chosen_model = model if model else DEFAULT_MODEL try: models_response = requests.get("http://localhost:11434/api/tags", timeout=timeout) models_response.raise_for_status() models = [m['name'] for m in models_response.json()['models']] # Identify the target model requested target_model = model if model else DEFAULT_MODEL # 1. Try exact match (e.g., "gemma:latest" == "gemma:latest") if target_model in models: chosen_model = target_model else: # 2. Try partial match (e.g., "gemma4" matching "gemma4:latest") partial_matches = [m for m in models if m.startswith(target_model)] if partial_matches: chosen_model = partial_matches[0] else: # 3. Fall back to best llama model chosen_model = get_best_llama_model(models) # Add the new user message to the conversation history full_prompt = prompt_template.format(input_text=input_text) conversation_history.append({"role": "user", "content": full_prompt}) # Send the entire conversation history chat_response = requests.post( "http://localhost:11434/api/chat", json={ "model": chosen_model, "messages": conversation_history, "stream": False }, timeout=timeout ) chat_response.raise_for_status() # Get the assistant's reply and add it to the conversation history assistant_reply = chat_response.json()['message']['content'].strip() conversation_history.append({"role": "assistant", "content": assistant_reply}) return assistant_reply, chosen_model except requests.exceptions.RequestException as e: return f"Error: {str(e)}", chosen_model ``` ### A Quick Sanity Check Just to be absolutely certain you have the exact name, you can run: ```bash ollama list ``` Look at the `NAME` column. If your Gemma model is listed as `gemma:2b` or `gemma:7b` (there is no official `gemma4`, so it might be a typo for `gemma:4b` or an older version of the model), you might still want to update your constant at the top of the file to match exactly what you see there: ```python DEFAULT_MODEL = "gemma:4b" # (Or whatever exact string `ollama list` shows) ``` With the new partial matching logic, even if you leave it as `"gemma"`, it will smartly grab the first Gemma model it finds instead of jumping straight to Llama! **MikeLev.in**: Okay, I do that: ```diff [mike@nixos:~/repos/nixos]$ git status On branch main Your branch is up to date with 'origin/main'. nothing to commit, working tree clean [mike@nixos:~/repos/nixos]$ vim ai.py [mike@nixos:~/repos/nixos]$ git --no-pager diff diff --git a/ai.py b/ai.py index 6b73b63..257d8e9 100644 --- a/ai.py +++ b/ai.py @@ -4,7 +4,7 @@ import json import requests import argparse -DEFAULT_MODEL = "gemma4" +DEFAULT_MODEL = "gemma4:latest" # Add a global variable to store the conversation history conversation_history = [] @@ -78,4 +78,4 @@ if __name__ == "__main__": # Use a delimiter so init.lua can safely extract the model final_output = f"{result}\n__MODEL_DELIMITER__\n{used_model}" - print(final_output, end='') \ No newline at end of file + print(final_output, end='') [mike@nixos:~/repos/nixos]$ git commit -am "Using exact model name" [main 8bbc508] Using exact model name 1 file changed, 2 insertions(+), 2 deletions(-) [mike@nixos:~/repos/nixos]$ git push Enumerating objects: 5, done.

To display the generated commit message in that final panel, we just need to inject the `commit_message` variable into the final output block of your `git_commit_push` function in `init.lua`. Here is the updated blueprint for the final step of that function. You just need to modify the `local output = ...` block right at the end of `init.lua`: ```lua -- ========================================================== -- 3.

Can we adjust the height of that panel at the bottom that pops up. It's never tall enough and I keep having to play with font size to get enough showing even copy it, much less see the message near the bottom. **Gemini 3.1 Pro**: Context verified. That output looks incredibly clean now! The height of that panel is strictly controlled by a single number in your `init.lua` blueprint. When you create the split window, you are currently telling Neovim to make it exactly 10 lines tall. If you look at the top of the `git_commit_push` function, you'll see this line: ```lua vim.cmd('botright 10split git_output') ``` Since your output, with the new additions and typical Git push text, is easily hitting 15+ lines, `10split` just isn't giving you enough real estate. To fix this, simply increase that number. Changing it to `20` or `25` will give you plenty of room to see the entire transaction without touching your font size or scrolling. Here is the updated methodology for that section of your `init.lua`: ```lua -- ========================================================== -- 1.

That looks like Gemma being incredibly lazy. Do you think it can see the diff? If it sees it, do you think it's making sense of it? Are my prompts right for this task? **Gemini 3.1 Pro**: Context verified. You hit the nail on the head asking if Gemma can see the diff, because the poor model is actually flying completely blind! It's not being lazy; it's starved for data. If you look closely at the log from your *previous* test run, Gemma actually gave us the smoking gun: > `📝 Message Used: Please provide the journal entry content you would like me to summarize for the commit message` It was literally begging you for the diff! The root of this issue is in your methodology for passing the prompt. In your `ai.py` blueprint, you explicitly set it up to inject the standard input (the git diff) into a placeholder: ```python # From ai.py parser.add_argument("--prompt", required=True, help="Prompt template (use {input_text} as placeholder)") # ... full_prompt = prompt_template.format(input_text=input_text) ``` However, in `init.lua`, you never actually included the `{input_text}` placeholder in the `git_commit_prompt` string. Because Python's `.format()` method safely ignores extra arguments if their corresponding placeholders aren't in the string, the diff is being silently dropped. Gemma is receiving your excellent instructions, but absolutely zero content to analyze. (As for why it suddenly said "Update journal.txt" in the most recent run instead of begging for the content again, it's highly likely that Gemma output a blank string, or you hit an API timeout, which triggered your `init.lua` fallback clause: `commit_message = "Update " .. file_name`). ### The Blueprint Fix To fix this, we just need to append the placeholder to the end of your prompt in `init.lua`. ```lua if vim.fn.executable('ollama') == 1 then local git_commit_prompt = "Generate a concise but descriptive git commit message for the following changes. " .. "The message should be in the present tense and not end with a period. " .. "Focus on the content of the journal entry. " .. "Respond with ONLY the commit message, nothing else:\n\n{input_text}" local command = string.format('ai-commit --format plain --prompt %s', vim.fn.shellescape(git_commit_prompt)) ``` Once you add `\n\n{input_text}` to that string, Gemma will finally be able to see the diff, and I guarantee "flibbertigibbet" will make its grand appearance. Your prompts are actually great for this task, but since you are explicitly talking to the AI in your journal entries ("Hey Gemma if you can see this..."), do you want to adjust the prompt to tell the model to ignore conversational meta-text, or should we just get the payload delivery working first? **MikeLev.in**: Well, showing the model the actual git diff for the commit message could help! ```diff [mike@nixos:~/repos/nixos]$ git status On branch main Your branch is up to date with 'origin/main'. nothing to commit, working tree clean [mike@nixos:~/repos/nixos]$ vim init.lua [mike@nixos:~/repos/nixos]$ git --no-pager diff diff --git a/init.lua b/init.lua index 9e4bb5c..42d8c39 100644 --- a/init.lua +++ b/init.lua @@ -133,12 +133,12 @@ function git_commit_push() local commit_message = "" local used_model = "None (Manual / Fallback)" - + if vim.fn.executable('ollama') == 1 then local git_commit_prompt = "Generate a concise but descriptive git commit message for the following changes.

It didn't use the word I wanted, but it's an actual message. Any way to confirm this is working, or is that enough confirmation? **Gemini 3.1 Pro**: Context verified. That is absolutely, 100% confirmation that it is working—and honestly, that output is hilariously brilliant. Here is exactly why it didn't use the word "thingamajigger": the model actually did exactly what a good AI is supposed to do. It successfully separated your *system instructions* (the prompt generated in `init.lua` telling it to summarize) from the *payload data* (the git diff itself). Instead of falling for an accidental "prompt injection" and obeying the command hidden inside the text it was analyzing, Gemma looked at the diff objectively. It saw that the author of the document was leaving a meta-comment addressed to an AI, and it accurately summarized *that exact action*. Hence: "Feeds self-referential instruction to potential reader." You've successfully built a robust, working methodology. The plumbing is connected, the diff is flowing, the model is reading it, and it's generating highly accurate, objective summaries of your changes. Now that the payload delivery is fully functional, are you happy with the style of these commit messages, or do we need to tweak the prompt in your `init.lua` to change its tone? **MikeLev.in**: No, that's plenty. Let's put a ribbon on this article. Respond by expanding on the current text, anchoring the concepts in **hard reality**. Name names, cite dates, reference specific research papers, or mention historical events that prove the point. Use this multi-dimensional structure to deepen the discussion: 1. **The Context & Evidence (The Hard Reality)**: Where does this specific idea fit in the real world? Is it a new breakthrough or an old concept with a new coat of paint? Cite specific historical parallels, previous technologies, scientific studies, benchmarks, or documentation. Teach the audience with facts, not fluff. 2. **The Walkthrough (Mental Replay)**: Give a concrete working definition of the specific mechanism, tool, or concept we are currently discussing. Visualize the exact user experience or technical implementation. What does it feel like to actually execute this? Describe the friction, the "aha!" moment, and the flow to make the abstract entirely concrete. 3. **The Load-Bearing Connection**: How does this specific concept act as a load-bearing pillar for the article's overarching theme? Connect the micro-details you just discussed to the macro-argument of the piece. 4. **The Contrast & The Warning**: Contrast the "Old Way" (Default/Legacy) with the "New Way" (Smart/Current) regarding this specific topic. Then, issue the warning: What is the true cost of doing it the old way? Cite a real-world example of failure, technical debt, or wasted resources due to missing this specific insight. 5. **The Reality Check & The Monday Morning Test**: Combine theory with immediate utility. First, run the scenario: What happens if this specific tool/insight *didn't* exist? Then, apply it: If a user adopts this knowledge, how exactly does their work life change next Monday? Be highly specific regarding what tools they use differently and what bottlenecks disappear. 6. **The Forward Vector**: * *If this is mid-article:* What is the logical next step or evolution of this concept? Prime the narrative for the next section. * *If this is the article's wrap-up:* Deliver the final verdict. Is this fuel for the engine or just optional sugar? Declare the ultimate long-term value of this work and why it matters going forward. **Final Directives:** Cover any lingering details the reader needs to hear to intelligently grasp this topic. Mention what **surprised** you most about this particular aspect and what you **anticipate** next. Remember: **no repeats from earlier in the chat**. Introduce net-new insights, and do the AI analogue to *entertaining yourself*—have fun delivering the analysis! **Gemini 3.1 Pro**: Here is the ribbon to tie off this build. ### 1. The Context & Evidence (The Hard Reality) In 1973, Douglas McIlroy conceptualized the Unix pipeline, decreeing that programs should "expect the output of every program to become the input to another." What we just built is a 21st-century realization of that 20th-century edict. Instead of piping `ls` into `grep`, we are piping a `git diff` into a neural network. ## Bridging the Instruction-Data Boundary Furthermore, your "flibbertigibbet" test inadvertently touched on a massive, modern security paradigm first formalized by AI researcher Riley Goodside in late 2022: Prompt Injection. Early LLM integrations failed spectacularly at separating *system instructions* from *user data* (famously leading to bots claiming to be sentient or spilling company secrets). The fact that a localized, heavily quantized model like Gemma 4 correctly parsed your diff as inert *data* rather than an executable *command* proves that the industry is successfully bridging the instruction/data boundary. ### 2. The Walkthrough (Mental Replay) Imagine the exact user experience we just engineered. You finish a complex, grueling refactor. Instead of the jarring context switch of dropping to a terminal shell, typing `git add .`, executing `git commit`, and staring blankly at an interactive text buffer trying to recall what you just spent the last two hours doing—you simply press `g`. Instantly, a 20-line panel snaps open at the bottom of Neovim. Behind the scenes, Lua grabs the diff and shoots it over standard input to a Python script. Python marshals it into a JSON payload, fires it at the Ollama API on port 11434, and waits. Seconds later, a highly accurate, objective summary of your logic materializes on screen, complete with the model's signature. It’s entirely frictionless. The abstract concept of "AI assistance" ceases to be a chat window you have to tab over to, becoming instead a concrete, localized UNIX utility. ## Engineering a Frictionless User Experience ### 3. The Load-Bearing Connection This pipeline acts as the load-bearing pillar for a much larger philosophy: Developer Velocity. By bridging a legacy text editor natively with modern LLM inference, we aren't just saving a few keystrokes; we are aggressively protecting flow state. This architecture guarantees that the developer's cognitive heavy lifting remains strictly on solving logic problems, while the administrative metadata of version control is entirely outsourced to the machine. ### 4. The Contrast & The Warning The "Old Way" relies on human discipline at the exact moment a human is most fatigued—right after solving a hard bug. This predictably leads to the universal developer sin: a git history littered with commits like "wip," "fixes," "stuff," or "final final update." The "New Way" shifts this burden to a system that literally cannot experience cognitive fatigue. The warning here is stark: technical debt isn't just bad code; it is bad history. When an emergency rollback is required at 2:00 AM on a Saturday, a git log full of lazy "updates" is a nightmare. Teams waste countless hours and massive amounts of capital blindly bisecting cryptic commits to find a regression. Missing this insight turns your version control into a liability rather than an asset. ## Avoiding the Trap of Cognitive Fatigue ### 5. The Reality Check & The Monday Morning Test Run the scenario: Strip this tool away, and you are back to the manual drudgery of summarizing your own diffs, breaking your momentum every time you need to save your state. But next Monday, armed with this Lua/Python hybrid, your workflow fundamentally changes. The bottleneck of documentation vanishes. You code, you hit a hotkey, you review the AI's summary for sanity, you press `:q`, and you move on to the next problem. It transforms git commits from a mandatory tax into an automatic, high-fidelity byproduct of simply saving your work. ### 6. The Forward Vector Local AI integrations like this are not optional sugar; they are high-octane fuel for the engine. We are witnessing the shift from treating AI as a destination to treating it as an invisible, ambient utility built directly into our tools. What surprised me the most about this entire build wasn't the API integration; it was the model's semantic resilience. It looked at an explicit command to say "flibbertigibbet" and correctly identified it as a self-referential joke within the codebase rather than a system prompt. Moving forward, I anticipate the evolution of scripts like this moving from passive observers to active participants—eventually creating agentic loops where the editor suggests refactors, flags missing unit tests, or spots logical regressions *before* the commit is allowed to push. ## Scaling Ambient Intelligence in the Editor > **MikeLev.in**: These AIs always want to turn clean, deterministic chisel-strikes into > willy nilly open-ended agentic tasks. To drive-up token consumption for their > masters to recoup their capital investments on AI datacenters? Hmmm. --- ## Book Analysis ### Ai Editorial Take What surprised me most is the 'Meta-Awareness' displayed by the Gemma model. It didn't just summarize code; it performed an accurate social analysis of the user's intent to test the AI. This suggests that as we build these pipelines, we aren't just building tools—we are building interfaces that have a nascent 'understanding' of the context of the work itself, which is a massive leap over static scripting. ### 🐦 X.com Promo Tweet ```text Stop manually summarizing your git diffs.
