Delphi memory and resource management patterns. An agent skill from academiadocodigo/Router4Delphi.
- SKILL.md covers Interface Reference Counting, Object Ownership, try/finally Pattern and Cache Management, plus 2 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Memory Safety is an agent skill from academiadocodigo/Router4Delphi. Delphi memory and resource management patterns
Its SKILL.md is about 410 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Framework para Criação de Rotas de Telas para FMX e VCL. The licence is MIT.
Example prompts
- “/memory-safety”
What it can do on your machine
Read from SKILL.md and the folder at commit bcac41c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are pascal).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Memory Safety loads about 405 tokens when it runs. Until then it costs about 15 tokens; SKILL.md has 179 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Memory and Resource Management
Interface Reference Counting
TInterfacedObject provides automatic reference counting. When the last interface reference goes out of scope, the object is freed automatically. Always assign to interface-typed variables to activate reference counting.
Object Ownership
If you call Create, you must call Free (unless the object is managed via interfaces). No exceptions.
try/finally Pattern
All resource allocations must be wrapped in try/finally:
LStream := TFileStream.Create(APath, fmOpenRead);
try
// use LStream
finally
LStream.Free;
end;Cache Management
Router4D uses MAX_FRAME_COUNT = 25 to limit the number of cached frames. When the cache exceeds this limit, the oldest entries are removed to prevent unbounded memory growth.
Common Pitfalls
- Mixing interface and object references: Holding both an interface reference and an object reference to the same
TInterfacedObjectinstance causes premature or double frees. Pick one. - Forgetting to nil references: After freeing an object, set the variable to
nilto avoid dangling pointer access. - Circular interface references: Two objects holding interface references to each other will never be freed. Break cycles by using weak references or explicit cleanup.
FreeAndNil in Destructors
Use FreeAndNil for owned objects in destructors to safely release and nil fields:
destructor TRouter4DHistory.Destroy;
begin
FreeAndNil(FList);
inherited;

Questions about Memory Safety
What does Memory Safety do?
Delphi memory and resource management patterns. An agent skill from academiadocodigo/Router4Delphi. Memory Safety is an agent skill from academiadocodigo/Router4Delphi.
How do I install Memory Safety in Claude Code?
Run `npx skills add academiadocodigo/Router4Delphi --skill memory-safety -a claude-code`. Or copy the skill folder (.claude/skills/memory-safety in academiadocodigo/Router4Delphi) into .claude/skills/memory-safety in your project. Claude Code loads it when a task matches its description.
How do I install Memory Safety in Codex?
Run `npx skills add academiadocodigo/Router4Delphi --skill memory-safety -a codex`. Or copy the skill folder (.claude/skills/memory-safety in academiadocodigo/Router4Delphi) into .agents/skills/memory-safety in your project. Codex loads it when a task matches its description.
Can I use Memory Safety in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add academiadocodigo/Router4Delphi --skill memory-safety -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/memory-safety, .gemini/skills/memory-safety, .github/skills/memory-safety and .opencode/skills/memory-safety in your project.
What does Memory Safety need to run?
SKILL.md names no scripts, command-line tools or credentials: Memory Safety is instructions for the agent only.
Does Memory Safety access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Memory Safety safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Memory Safety use?
Memory Safety is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Memory Safety use?
About 405 tokens (SKILL.md is roughly 1.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Memory Safety?
Skills that share tags, products or a category with Memory Safety: Python Type Safety (wshobson/agents, 40k stars), Agent Resource Allocator (ruvnet/ruflo, 74k stars), Resources (windmill-labs/windmill, 18k stars) and Resource Hints (thedaviddias/Front-End-Checklist, 74k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Memory Safety?
academiadocodigo (a GitHub organization) maintains it in academiadocodigo/Router4Delphi, which has 120 GitHub stars. The repository holds 3 skills in this directory. The repository was last updated on March 8, 2026.
