What it does

Dtvm Perf Profile is an agent skill from DTVMStack/DTVM. Profile DTVM execution using Linux perf and generate categorized analysis reports. Use when the user wants to profile a DTVM command, find performance hotspots, break down JIT-compiled EVM basic block execution time, analyze host function overhead, or mentions "perf", "profile", "hotspot", "breakdown", or "bottleneck" in the context of DTVM execution. The user provides a dtvm command line (including bytecode path, calldata, execution mode, etc.).

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/perf_profile.sh`).

It sits in Backend & APIs, covering Smart contracts. It works with Linux and WebAssembly. The repository describes itself as: DeTerministic Virtual Machine.

When your agent uses it

  • The user wants to profile a DTVM command
  • Find performance hotspots
  • Break down JIT-compiled EVM basic block execution time
  • Analyze host function overhead

Example prompts

  • “profile”
  • “hotspot”
  • “breakdown”
  • “/dtvm-perf-profile”

Requirements

  • A Bash shell

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Verify build flags
  2. Run the profiling script
  3. Interpret the summary
  4. Drill into hotspots
  5. Present findings

What it can do on your machine

Read from SKILL.md and the folder at commit 9190313. 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

    Ships 1 file in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • cmake

    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

Dtvm Perf Profile loads about 1.1k tokens when it runs. Until then it costs about 117 tokens; SKILL.md has 380 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~117
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 380 words (~1,106 tokens).

“Profile DTVM execution and produce a categorized performance report.”
