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 | $0.00172 |
| Opus 5.5 | $0.00000 | $0.00069 |
| Sonnet 5.5 | $0.00000 | $0.00034 |
| Haiku 4.5 | $0.00000 | $0.00017 |
Grade A, and why
build 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.
What it actually says
/build — Build the ShadowDusk solution
Builds the full solution in Release configuration and reports any errors.
dotnet build --configuration Release
If the build fails, read the error output carefully:
- CS errors: type/namespace issues — check
usingdirectives and project references - NETSDK errors: missing SDK, wrong TFM, or NuGet restore failure — run
dotnet restorefirst - Native tool errors: if
tools/binaries are missing, run./tools/restore.sh(or.\tools\restore.ps1) first
After a successful build, report:
- Which projects were built
- Any warnings (treat CA/analyzer warnings as worth mentioning)
- Output binary locations under
bin/Release/
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.

build is a command published in the GitHub repository kaltinril/ShadowDusk (19 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 172 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 2026-09-04.

test
Run .NET TDD workflow — write failing xUnit/MSTest tests, implement, verify. For bugs, use the Prove-It pattern.

Commands for creating C# script files, attaching MonoBehaviours to GameObjects, and reading/writing serialized fields. Writing a .cs file does not make its type available — Unity must import and compile it (a domain reload) first. The flow is: createscript → recompile → poll recompilestatus (until completed/uptodate)…
