Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.01443 |
| Opus 5.5 | $0.00000 | $0.00577 |
| Sonnet 5.5 | $0.00000 | $0.00289 |
| Haiku 4.5 | $0.00000 | $0.00144 |
Grade A, and why
memoryprofiler scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unity Open MCP — Memory Profiler Extension
Skill for AI agents capturing Unity Memory Profiler snapshots
(com.unity.memoryprofiler) in a Unity project through the unity-open-mcp
MCP server.
This domain is embedded in the bridge, compile-gated on
com.unity.memoryprofiler, and auto-activating. Its tool compiles in only when the project hascom.unity.memoryprofilerinstalled (the bridge sets theUNITY_OPEN_MCP_EXT_MEMORYPROFILERdefine automatically). When the package is present, thememoryprofilergroup activates automatically for the session — the tool appears inListToolswith no manualmanage_toolscall.
Preconditions
- Unity Editor is open with the target project.
unity_open_mcp_pingreturnsconnected: true.- The project has
com.unity.memoryprofilerinstalled. Ifcapabilitiesreports thememoryprofilergroup asavailable: false, install the package (Package Manager → Unity Registry → Memory Profiler) and let the bridge recompile. - The
memoryprofilergroup is auto-activated when the package is present — checkunity_open_mcp_manage_tools(action="list_groups"); the group should showactivationSource: "auto". If you deactivated it manually, re-activate withmanage_tools(action="activate", group="memoryprofiler").
Tool
unity_senses_memory_snapshot_capture — capture a Memory Profiler snapshot to
a .snap file. (Sense-prefixed because it pairs with the existing senses
profiler family rather than the typed-editor surface.)
Vocabulary
A Memory Profiler snapshot (.snap file) is an offline capture of the
entire managed + native heap at a moment in time — far deeper than the live
unity_senses_profiler_memory allocator-bytes read. It can be opened in the
Memory Profiler window (Window > Analysis > Memory Profiler) for root-cause
analysis of leaks, large allocations, and asset footprint.
Version-stability note
The Memory Profiler capture surface moved namespaces across Unity versions:
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

memoryprofiler is a skill published in the GitHub repository AlexeyPerov/Unity-Open-MCP (17 stars, last pushed 14d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,443 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

ahk-triage
Triage a bug or unexpected behavior. Deep diagnostic analysis with structured report. No tasks created, no harness tracking.
ahk-ask
Ask a question about this codebase — where is X, does Y exist, how does Z work. Read-only. No tasks created, no harness tracking.
asset-audit
Audits game assets for compliance with naming conventions, file size budgets, format standards, and pipeline requirements. Identifies orphaned assets, missing references, and standard violations.
hotfix
Emergency fix workflow that bypasses normal sprint processes with a full audit trail. Creates hotfix branch, tracks approvals, and ensures the fix is backported correctly.
root-cause
Use when any test fails, bug appears, or behaviour surprises you, before proposing a fix - find the cause and prove it, by reading real evidence, tracing bad values back to their origin, comparing against a working case, and testing one hypothesis at a time.

Inspect, automate, and debug a running Unity Editor. Use for Unity scenes, assets, project state, Console logs, and Editor C# execution.
