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.

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 | $0.00136 | $0.02310 |
| Opus 5.5 | $0.00054 | $0.00924 |
| Sonnet 5.5 | $0.00027 | $0.00462 |
| Haiku 4.5 | $0.00014 | $0.00231 |
Grade A, and why
aspid-serializable-type 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 4d 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Serializable types and [TypeSelector]
Namespace Aspid.FastTools.Types. If the user's scripts have an .asmdef, it must reference Aspid.FastTools
(editor code using TypeField or TypeSelectorWindow also Aspid.FastTools.Editor).
| Need | Use |
|---|---|
| Store a type, create the instance in code | SerializableType<T> |
| Same, but survive renaming/moving the class with its file | SerializableMonoScript<T> |
Picker on a string (stores the assembly-qualified name) or extra constraints |
[TypeSelector] |
| Store an instance with data of a chosen implementation | [TypeSelector] + [SerializeReference] |
| Switch a MonoBehaviour/ScriptableObject to a sibling subclass | ComponentTypeSelector, see references/more.md |
| Type dropdown in a custom inspector or editor window | TypeField, see references/more.md |
| Open the picker from custom editor code | TypeSelectorWindow.Show, see references/more.md |
Fail a CI job on missing types or unset Required fields |
SerializeReferenceCiGate.RunCheck, see references/more.md |

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.

aspid-serializable-type is a skill published in the GitHub repository VPDPersonal/Aspid.FastTools (24 stars, last pushed today), licensed MIT. It adds 136 tokens to every session and 2,310 once invoked, about $0.0005 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 2026-09-26.
