Show HN: Graphicle, a Rust port of Graphify with memory for coding agents

Hacker News Discussion

📝 Discussion Summary (Click to expand)

Theme 1: Need for rigorous, controlled evaluation
Many commenters stress that memory‑tool assessments must follow proper experimental design—pre‑registered tests, control groups, and attention to confounders.

“Yeah learn how to do even the basics of science, please. Control groups!! Confounders!!” – NewJazz

Theme 2: Skepticism about current memory tools’ usefulness
Several users report that the tools either fail to improve agent performance or actually hinder it, citing worse results than raw baselines and mismatched output formats.

“Has anyone actually gotten good results out of this? … these memory systems did worse than the raw harness given ripgrep.” – theLiminator
“… a lot of structured information returned that the model (and harness) isn’t set up to work with effectively.” – NewJazz

Theme 3: Concerns over reliance on LLM‑based judging and limited benchmarks
The practice of using another language model to score answers is questioned as insufficient, and the narrow set of public benchmarks is seen as inadequate for real‑world agent performance.

“We used one open model to read and judge the answers for every tool, so it's the same setup for all of them.” – KarLexAI
“Letting another LLM decide quality probably isn't the only meterstick you want, either.” – NewJazz

🚀 Project Ideas

AgentEval Harness

Summary

  • A reproducible, open‑source evaluation framework that lets developers run coding‑agent tasks (e.g., language translation, bug fixing, feature addition) with and without memory tools, measuring task success, token usage, tool calls, and time while enforcing control groups.
  • Core value proposition: eliminates the ad‑hoc, time‑consuming process of building eval environments and provides standardized metrics so teams can objectively compare memory‑augmented agents.

Details

Key Value
Target Audience AI researchers, LLM agent developers, tool builders evaluating memory or reasoning extensions
Core Feature Task runner with pluggable environments (e.g., RealWorld app conversion), automated scoring, token/time tracking, and built‑in control‑group comparison
Tech Stack Python, Docker, pytest, OpenAPI for task definitions, Prometheus/Grafana for metrics
Difficulty Medium
Monetization Hobby

Notes

  • HN commenters lamented the lack of proper evals and control groups: “I’m not looking to be convinced about this tool as much as I am genuinely looking for a way to eval these kinds of tools in general” (pjm331) and “Control groups!! Confounders!!” (NewJazz).
  • Provides a concrete platform for the discussion’s demand for scientific evals, encouraging reproducibility and deeper tool insights.

Structured Output Adapter

Summary

  • A lightweight middleware layer that converts the rich, structured outputs of memory tools (e.g., Graphicle’s graphs, Mem0’s triples) into prompt‑compatible snippets or action tokens that existing LLM harnesses can consume directly.
  • Core value proposition: bridges the mismatch between tool output format and agent input expectations, reducing wasted token cycles and improving agent performance without retraining.

Details

Key Value
Target Audience Developers integrating memory tools into LLM agents, agent framework maintainers
Core Feature Configurable translators (JSON‑schema → prompt fragments, graph → natural language description) with plug‑in support for popular memory tools
Tech Stack TypeScript/Javascript, JSON‑Schema, Jinja2 templating, Node.js or Python backend
Difficulty Low
Monetization Hobby

Notes

  • Commenters noted the friction: “I read through the skill file of graphify and ran some of the commands it was telling the agent to run… the model (and harness) isn’t set up to work with effectively” (NewJazz) and “The more structure you give it the worse it performs” (nonethewiser).
  • By providing a ready‑made adapter, agents can leverage structured memory without re‑engineering their harness, addressing the core frustration.

AgentEval Cloud

Summary

  • A hosted SaaS that lets teams submit agent configurations and memory tools, runs side‑by‑side evaluations on a curated task suite, applies statistical analysis (confidence intervals, p‑values), and returns shareable reports.
  • Core value proposition: turns the painful, manual process of comparing multiple memory‑augmented agents into a push‑button experiment with rigorous analytics.

Details

Key Value
Target Audience Product teams, AI labs, tool vendors wanting to benchmark their extensions
Core Feature Automated experiment orchestrator, result dashboard with exportable CSV/PDF, API for CI integration
Tech Stack Go/Node.js backend, Kubernetes for isolated task containers, React frontend, Postgres for results
Difficulty High
Monetization Revenue-ready: Subscription tiered by monthly evaluation minutes ($49 / $199 / custom)

Notes

  • Users asked for ways to see if agents “actually finish more tasks with these tools” and wanted to compare “how many tasks pass, tokens used, tool calls and time” (pjm331). AgentEval Cloud directly supplies that.
  • Hosted service lowers barrier to entry for teams lacking infra, fostering discussion and adoption of better evaluation practices in the community.
