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 | $0.00044 | $0.01801 |
| Opus 5.5 | $0.00018 | $0.00720 |
| Sonnet 5.5 | $0.00009 | $0.00360 |
| Haiku 4.5 | $0.00004 | $0.00180 |
Grade A, and why
uloop-hot-reload 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 15d 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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
uloop hot-reload
Replaces method bodies in the running Editor (EditMode or PlayMode) directly from edited
project source files — no domain reload, no attributes, no source markers. Private/internal
member access, static methods, return values, async methods, and iterators all work within
the limits below, including private access inside async, iterator, lambda, local-function,
and LINQ-query bodies. Methods that cannot be patched are reported as Skipped or Failed;
one unpatchable method never aborts the rest of the run.
Outcome says whether the edit is live (ReplacedByCompile: a fallback compile succeeded, so
it is compiled in and no patch is active).
Usage
uloop hot-reload --files Assets/Scripts/Enemy.cs
uloop hot-reload --files Assets/Scripts/Enemy.cs,Assets/Scripts/Boss.cs
uloop hot-reload
uloop hot-reload --files Assets/Scripts/Enemy.cs --compile-on-skip off
uloop hot-reload --revert-all
Multiple files are one comma-separated value (or a JSON array); array options consume exactly one value token.
A script under a brand-new .asmdef cannot be hot-reloaded before its first import: Unity
has not created that assembly yet. Run uloop compile once, then iterate with hot reload.
A new file under an existing .asmdef can be hot-reloaded, but it is never selected
automatically — pass it with --files.
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
--files |
array | - | Project-relative .cs paths to hot-reload (method bodies, added members, and new top-level types). When omitted or empty on apply, selects compiled snapshot sources only — those whose bytes changed since the last compile snapshot, capped at 50 changed files per assembly with a warning when the cap trims the list; a file that has never been compiled is never selected and must be passed explicitly, except an introduced type's file after Play Mode entry or --revert-all, which is selected again; run uloop compile first when no snapshot exists, or pass explicit paths when no changed source is found |
--revert-all |
flag | - | Remove every active hot-reload patch and added member and clear the ledger; introduced types stay loaded until the next domain reload. When set, --files is ignored |
--status |
flag | - | Lists the currently active changes (patched methods, added members, and introduced types) without applying or reverting anything. |
--compile-on-skip |
enum | auto |
When edits stay unapplied (Skipped/Failed methods, Failed types; a re-bound sibling's Skipped rows and uncompared bodyless members aside), run uloop compile in this command: auto only in Edit Mode (never stops a Play session), on always unless Unity holds compiles until Play ends, off never. The response's CompileFallback says which; when the compile ran, Compile carries its result and Success is the compile's. |
What ships with it
7 files 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.

uloop-hot-reload is a skill published in the GitHub repository hatayama/unity-cli-loop (586 stars, last pushed 2d ago), licensed MIT. It adds 44 tokens to every session and 1,801 once invoked, about $0.0002 per session on Opus 5.5. 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.
