What it does
Analyze Owl Capture is an agent skill from OwlcatGames/OwlcatMonoProfiler. Analyze a saved .owl memory capture (find leaks, growth, top allocators) using the owlquery serve-mode HTTP API. Use when asked to analyze a capture, investigate memory growth/leaks in a profiling session, or answer questions about what a game allocated.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering REST APIs. The licence is MIT.
When your agent uses it
- Asked to analyze a capture
- Investigate memory growth/leaks in a profiling session
- Answer questions about what a game allocated
Example prompts
- “/analyze-owl-capture”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Always use serve mode — opening a capture unpacks gigabytes to %TEMP%;
- Replays cost time; ranges are your budget. Any live-objects query
- Reuse ranges. The server caches the last TWO replays by exact
- Requests are sequential: a long replay delays the next query — use a
What it can do on your machine
Read from SKILL.md and the folder at commit c5a4b80. 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
Shell commands in SKILL.md call:
curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.
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
Analyze Owl Capture loads about 1.1k tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 525 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.

- description
- Analyze a saved .owl memory capture (find leaks, growth, top allocators) using the owl_query serve-mode HTTP API. Use when asked to analyze a capture, investigate memory growth/leaks in a profiling session, or answer questions about what a game allocated.
Analyzing an .owl capture
owl_query answers aggregate questions about a capture as JSON. Full reference:
doc/owl_query.md. Binary:
build\owl_query\Release\owl_query.exe (build target owl_query if missing).
Rules
- Always use serve mode — opening a capture unpacks gigabytes to %TEMP%;
one-shot mode pays that on every query.
- Start in background:
owl_query <capture.owl> serve --port 8890 - Wait for the ready line
{ "serving": ... }on stdout (a 250 GB capture takes ~2 min to open). - Query with any HTTP client:
curl "http://127.0.0.1:8890/top-types?from=A&to=B" - Always finish with
curl http://127.0.0.1:8890/shutdown— it releases the multi-GB temp extraction.
- Start in background:
- Replays cost time; ranges are your budget. Any live-objects query
(
/top-types,/growth,/callstacks,/objects) replays its frame range at roughly 6–8 M events/s (measured: ~80 M events ≈ 12 s; 6.5 B events ≈ 13 min)./summaryand/framesare SQL-backed and instant. Narrow the range before reaching for replay-backed queries. - Reuse ranges. The server caches the last TWO replays by exact
(from,to). Drill down with identical ranges:
top-types→callstacks→objectsover the same from/to costs one replay.growthreuses a cached window too. - Requests are sequential: a long replay delays the next query — use a generous HTTP timeout instead of retrying (retries just queue up).
Workflow: "where does memory go / what leaks?"
/summary— frame range, event counts, heap peaks. Sanity-check scale before anything else./frames?buckets=200— locate wheretracked_heap_bytes(orcommitted_bytes) grows or spikes./top-types?from=A&to=Bover the growth region — what accumulates. "Live" = allocated in range, not freed in range → leak candidates./growth?base_from=..&base_to=..&from=..&to=..— compare two comparable windows (same level, same activity); types with positivedelta_bytesthat persist across windows are the real suspects./callstacks?type=<suspect>&from=A&to=B(same range as step 3 — cache hit) — the allocation sites responsible./objects?type=<suspect>for concrete instances if needed./shutdown.

Symbolicating native frames
Native frames show as Module.dll+0xRVA until a PDB search path is set.
When the analysis leads into native memory (Unity Heap, HeapAlloc,
VirtualAlloc types, or stacks dominated by raw UnityPlayer.dll+0x...
frames), symbolicate before drawing conclusions:
- Ask the user where the build's PDBs are — do NOT guess or scan the
disk. Typically it's the game build directory (containing the exe,
UnityPlayer*.pdb, and for IL2CPPGameAssembly.pdb). Ask for the build that matches the capture: mismatched PDBs resolve to wrong names. curl "http://127.0.0.1:8890/symbols?paths=<url-encoded dirs>"(';'-separated). Poll/symbols/statusevery few seconds untilpendingis 0 (about a minute for a large capture — big PDBs load once).- Re-run
/callstacks— same range hits the replay cache, and the text is now resolved. If a response carriessymbolication_pending, it raced the resolver: wait and re-request. - Check
unresolved_modulesin/symbols/status. Windows system DLLs (ntdll.dll,KERNEL32.DLL, video drivers…) being listed is normal — ignore them. If a module that matters is listed — the game exe,UnityPlayer.dll,GameAssembly.dll,mono-2.0-bdwgc.dll, or a game plugin — tell the user which modules stayed unresolved and ask where their PDBs are rather than analyzing raw addresses.
Reading the output
- Type names mix managed (
System.String) and native hook labels (Unity Heap,HeapAlloc,VirtualAlloc (commit)).VirtualAllocsizes are reserve/commit ranges — expect few, huge "objects". - Native stack frames appear as
Module.dll+0xRVAuntil symbolicated (see above). type_id/callstack_idare stable within one capture only.- Numbers match the UI exactly (same client library, same queries).
