I recently started playing around with Codex and ran into an issue where there was a DMD compiler error and the agent didn't use dustmite to reduce it until afterward when I asked it to. So I'm curious if anyone out there has put together D-specific agent skills? And also in general, what skills do people find useful when programming with D?

And also in general, what skills do people find useful when programming with D?I don't have anything that I'd share publicly, due to the specific nature of the work I'm doing, but in general terms I create skill files that capture processes and preferences. For example, when I translate C code to D, I want the for loops converted to foreach loops, I want to change i and j indexes to ii and jj indexes, and that sort of thing. I record these preferences in one or more skill.md files as I go. Model quality with D can vary, so sometimes putting knowledge in skill files delivers more accurate results. (This is more relevant for local models like Qwen 3.6 or Gemma 4 than for Codex.)

So I'm curious if anyone out there has put together D-specific agent skills? And also in general, what skills do people find useful when programming with D?Hi, I have not found any skills for D so I created one myself. But I call it a meta-skill as it contains a few sub-skills: * `SKILL.md` - the main skill definition (name, description, usage trigger, D language cheat sheet) * `references/language.md` - full D language reference (types, memory model, templates, CTFE, etc.) * `references/phobos.md` - Phobos standard library reference * `references/vibed.md` - vibe.d web/async framework reference * `references/vibe-mongodriver.md` - MongoDB driver reference * `references/postgresql.md` - PostgreSQL driver reference * `references/minio-d.md` - MinIO/S3 client reference You can download it here: https://filebin.net/ujzo12h8saouczug It will be available for 6 days from the time of my post. I would have given a git link, but I host git myself with Gitea and something happened to my server - cannot access it for now. I will check it when I get home and then post the link.

Even in the case the skill is useful your original prompt was likely smaller and by virtue of your prompt generating it from a one-way process of ai "thinking", was part of a greater connected component of useful thought-vectors

Maybe size of skills depends on the capability of the model you're using.Well, the `SKILL.md` is small and similar to table of contents with some description and additional instructions. It only explains the basics, and what reference documents to look up and when it might need them. Then LLM looks up the relevant reference it needs. **It does not read the entire skill at once.**

Even if it is not supported, you can simply create an agent and/or MCP that will connect to Jira and sync all issues with Multica. Another option is to simply vibe-code it with LLM. I have added admin panel this way to configure multiple users.Originally, I created them at my company to use with [Multica](https://github.com/multica-ai/multica) agent orchestrator to aid the fast-paced development cycles; revised them multiple times.Does Multica support JIRA by any chance?

This is an attack vector for the LLM, but so it foreign code so it can rely on the same trust system that already exist.

This study found security issues in 37% of posted skills: https://snyk.io/blog/toxicskills-malicious-ai-agent-skills-clawhub/ That's likely due to a high correlation between AI use and not bothering to read code.

Dub can expose a simple command showing the git repository name from which harness can be installed. Nicer, but more costly would be for it to share the commands for different harnesses as well.
