  • We aim to achieve four core objectives for a dedicated role-playing model: simplified prompt engineering, highly stable output quality, built-in domain world knowledge, and high-efficiency deployment with a small parameter size.
  • However, effectively injecting deep domain knowledge often leads to a severe catastrophic forgetting of the model's general agent capabilities.

Straight from my .agents directory.

What's new

Approaches like GSD, BMAD, and Spec-Kit try to help by owning the process.

Key details

  • My agent skills that I use every day to do real engineering - not vibe coding.
  • Developing real applications is hard.
  • Approaches like GSD, BMAD, and Spec-Kit try to help by owning the process.
  • But while doing so, they take away your control and make bugs in the process hard to resolve.

Results & evidence

  • If you want to keep up with changes to these skills, and any new ones I create, you can join ~60,000 other devs on my newsletter: Two ways in, two philosophies.

Limitations / unknowns

  • Generalization outside curated tasks is still unclear.

Next-step validation checks

  • Reproduce one claim with a public baseline and fixed evaluation settings.
  • Check robustness on out-of-distribution or long-context cases.
  • Track whether independent teams report matching results.

  • This repository is closer to a museum exhibit than a product pitch, a crustacean-run artifact kept alive by clawed gajaes, swept and labeled by agents, and automatically maintained according to the harnesses above.
  • As already described in the project philosophy, this is not meant to be hand-operated like a normal product repo.
  • It is an agent-managed exhibit: the harnesses plan, execute, verify, label, and preserve the artifact while the crabs keep the tank running.

Results & evidence

  • No hard numbers surfaced in the source text; treat claims as directional until benchmarks appear.

  • Generalization outside curated tasks is still unclear.

Prompt Revision as a Source of Cultural Bias in Text-to-Image Systems

Signal 9.4 Novelty 4.0 Impact 2.0 Confidence 7.5 Actionability 5.2

Summary: arXiv:2609.11532v1 Announce Type: new Abstract: Commercial text-to-image systems silently revise user prompts before generating images, a step users typically cannot disable or.

arXiv:2609.11532v1 Announce Type: new Abstract: Commercial text-to-image systems silently revise user prompts before generating images, a step users typically cannot disable or even see.

Key details

  • Yet, existing audits of cultural bias examine only the final images and treat generation as a single pipeline, so they cannot tell where the bias originates.
  • We introduce WORLDVIEW, a multilingual benchmark of 8,960 prompts across 15 languages and 31 language-context pairings.
  • Using it, we audit the revision layer in three systems (DALL-E-3, Imagen-4, GPT-Image-1.5) through a three-step analysis of how heavily it marks each cultural context, whether it flattens that context into a narrow vocabulary, and whether that vocabulary is...
  • Relative to a no-context English baseline, the US is the least-marked context, while non-Western and non-Anglophone contexts are marked far more heavily, flattened into narrow vocabularies applied across topically diverse prompts, and reduced to recognizabl...
