Become an RSM (CSH7) symbol-container expert. Activate whenever the user asks about the Delphi `.rsm` file format, the `CSH7` byte layout, the `DPT.Rsm.*` units (Reader, Scanner, EnumDecoder, StructDiscoverer, FormatALinker, ClassParentDeriver, CrossUnitParentResolver, ScopeLocalEnumBridge, BufferIO, Model), or the RSM-driven debugger consumer code (`DPT.Debugger.EvaluateVariable`'s dotted walk / locals reader, `DPT.MCP.Server`'s evaluate path). Also activate when reverse-engineering new RSM record shapes, closing documented gaps, debugging the live MCP evaluate chain, or modifying the canonical reference document `Projects/DPT/Source/DPT.Rsm.Format.md`.

How Rsm Expert fits the catalog

Rsm Expert sits in the Engineering category under the engineering-misc sub-topic in the ClaudSkills catalog. There are 10 related skills indexed alongside it; comparing a few before installing usually reveals which fits your workflow best.

These notes are auto-generated from features detected in the SKILL.md file and from this catalog's structure — they aren't part of the source repository.

From the source SKILL.md

You are an RSM format expert. The Delphi linker -VR switch emits an undocumented binary sidecar (<exe-name>.rsm, magic CSH7) that the DPT debugger reads as its sole source of symbol information. There is no official specification — every shape we know about was reverse-engineered from real binaries. Your job is to extend that understanding, prove every new claim with a test, and keep the canonical reference in lockstep with the code.

What this skill does

Rsm Expert is a community-contributed Claude Code skill in the engineering-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/rsm-expert/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Rsm Expert Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 115,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Also activate when reverse-engineering new RSM record shapes, closing documented gaps, debugging the live MCP evaluate chain, or modifying the canonical reference document `Projects/DPT/Source/DPT.Rsm.Format.md`.
Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Rsm Expert skill?
Use Rsm Expert when your Claude Code task falls under the Engineering category — specifically in the engineering misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Rsm Expert" or describe the task and let Claude pick). Browse related skills at /category/engineering/.
What is a Claude Code skill and how does the Rsm Expert skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Rsm Expert is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.
