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 | $0.00085 | $0.01764 |
| Opus 5 | $0.00043 | $0.00882 |
| Sonnet 5 | $0.00017 | $0.00353 |
| Haiku 4.5 | $0.00009 | $0.00176 |
Grade A, and why
studio-project-scaffold 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 today.
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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Studio Project Scaffold
Overview
Create the minimum project-local governance, project profile, routing references, and agent-role overlay needed for safe multi-session work while preserving existing instructions, configuration, skills, and agents.
Newly generated profiles include optional studio_experience defaults for role, mode, and enabled intents. These defaults affect routing presentation only. Use gamestudio guide for a report-only Golden Path packet; gamestudio init --apply remains a separate reviewed mutation.
When to use
Use for a new game repository, an inherited legacy project without agent governance, or a project that needs standardized ownership, evidence labels, and handoff state.
When NOT to use
Do not overwrite a mature project-local .agents/ system, existing AGENTS.md, HANDOFF.md, or skills. Generate a report and merge plan instead.
Required inputs and context discovery
Collect workspace root, nested Git roots, Git state, existing governance files, Unity markers, server projects, Lua/data trees, database inputs, generated, cache, vendor, and excluded paths, project-local skill IDs, agent files, and .codex/config.toml state.
Safety and risk level
Scaffolding and the per-project adapter are medium-risk because they write governance and agent files. Run report-only first, preserve every existing file by default, and never mutate external projects during kit tests.
Workflow
- Scan structure read-only and detect Unity, server, Lua, database, tooling, and generated subsystems. Completion criterion: detected subsystems and unknown areas are reported.
- Inventory existing
AGENTS.md,HANDOFF.md,.agents/, local skills, and ignore rules. Completion criterion: every existing governance artifact is marked preserve, merge, or BLOCKED. - Render the minimum scaffold with evidence, ownership, repeated-work tooling, mutation, generated-file, no-touch rules, project profile, workspace map, validation matrix, and adapter references.
Completion criterion:
scaffold-report.jsonlists exact proposed and preserved scaffold files without writes. - Run the per-project adapter report-only first. Review
plan_digest,proposedplanned paths,collisions,activated_roles,scope_review, preserved paths, and the action/hash details undermutation_report.operations. Broad resolved capability intersections are advisory; only out-of-scope or duplicate exact active write assignments block orchestration. Completion criterion: the reviewed adapter report identifies every proposed write and collision without mutation. - Apply only that reviewed adapter plan with a named reviewer, a disjoint project-local backup root, and the approved plan digest. Generate and review a new report when the digest is stale. Completion criterion: apply uses all three gates and returns its manifest and restore command.
- Materialize roles from packaged generic agent templates plus profile and inferred specialists under
.codex/agents/, preserving an explicit projectreasoning_effortover the template default. The generated.codex/agents.generated.tomlfile remains inert until manual merge, and the adapter leaves.codex/config.tomluntouched. Completion criterion: unmanaged agents and active configuration remain preserved, and effective scopes are reviewed only after role resolution. - Record per-file ownership hashes under
.agents/registry.json, then run project-local validation and inspect the generated handoff snapshot. Completion criterion: scaffold output is parseable and unresolved runtime facts remain Unverified or BLOCKED. - Run uninstall report-only first and review its
plan_digest,proposed,preserved_drift, andremaining_ownedpaths. Apply only with a named reviewer, a disjoint backup root, and that matching digest. Use hash-safe uninstall: remove only files matching recorded ownership hashes. Preserve drift and returnPARTIALwithpreserved_driftandremaining_ownedfor manual recovery when safe cleanup cannot finish. Completion criterion: uninstall never deletes unmanaged or drifted project content and cannot bypass the approval gates.

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.

studio-project-scaffold is a skill published in the GitHub repository hoatv2211/GameStudio-CodexKIT (3 stars, last pushed yesterday), licensed MIT. It adds 85 tokens to every session and 1,764 once invoked, about $0.0004 per session on Opus 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.
