What it does
Alloc Profile is an agent skill from timeplus-io/proton. Analyze jemalloc or async-profiler allocation profiles in collapsed stack format. Make sure to use this skill whenever the user mentions memory profiling, heap analysis, allocation hotspots, jemalloc, async-profiler, collapsed stacks, .folded files, or asks about memory usage patterns.
Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/analyze_alloc_profile.py`).
It sits in Development, covering Performance optimization. The repository describes itself as: The Fastest Unified Streaming SQL Engine in a Single C++ Binary. ⚡ Millisecond latency. 100+ GB/s throughput. Continuously compute real-time context from streams, logs, metrics… The licence is Apache-2.0.
When your agent uses it
- The user mentions memory profiling
- Allocation hotspots
- Collapsed stacks
- Asks about memory usage patterns
Example prompts
- “/alloc-profile”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- biggest operations by memory share
- likely owning subsystem
- likely next inspection target in code
- whether the profile looks like steady-state memory, burst allocation, or leak-like retention
What it can do on your machine
Read from SKILL.md and the folder at commit 1c47e60. 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/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
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
Alloc Profile loads about 489 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 172 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); the scripts in this folder are not scanned.

- description
- Analyze jemalloc or async-profiler allocation profiles in collapsed stack format. Make sure to use this skill whenever the user mentions memory profiling, heap analysis, allocation hotspots, jemalloc, async-profiler, collapsed stacks, .folded files, or asks about memory usage patterns.
Allocation Profile
Inputs
$0(optional): path to a.collapsedor.foldedprofile
If no path is given, search near the current directory:
find . -maxdepth 4 \( -name "*.collapsed" -o -name "*.folded" \) | sortTooling
Use the bundled analyzer script:
python3 .claude/skills/alloc-profile/scripts/analyze_alloc_profile.py <profile>What the analyzer reports
- Total samples/bytes and unique stack traces
- Top stack traces
- Top outermost meaningful frames
- Top leaf allocation frames
This gives both:
- "why did we allocate?" via outermost frames
- "what code actually allocated?" via leaf frames
Interpretation guidance
- Large outermost buckets often point to the higher-level operation to optimize first.
- Large leaf buckets inside allocators or containers are usually symptoms; look one or two frames above for product code.
- For streaming paths, pay special attention to joins, windows, aggregation state, and block materialization.
- For historical paths, focus on scans, merges, deserialization, and sort/aggregation buffers.
