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 | $0.00052 | $0.03509 |
| Opus 5.5 | $0.00021 | $0.01404 |
| Sonnet 5.5 | $0.00010 | $0.00702 |
| Haiku 4.5 | $0.00005 | $0.00351 |
Grade A, and why
cs2-game-update 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 10d 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sweeping the repo for a game update
The game moved and the prose did not. This skill diffs the two decompile commits, re-derives every claim the diff reaches, and ends with every Verified against game version line on the new version, each one earned.
It works from the decompile as it stands: cs2-modding-setup owns the decompile, its per-version commits, its tool pin and the readable UI bundle copy, and its refresh branch runs first. Where ~/.cs2-modding/setup.md records a game version newer than the decompile's HEAD, say so and stop there.
Where the decompile diff touches src/cohtml.Net/Properties/AssemblyInfo.cs, the embedded engine moved: say so, and name gameface-update as the sweep for the coherent-gameface plugin. The docs/research/ lines recording the Cohtml version a live read observed stay this sweep's own.
1. Fix the two versions
- New:
VersionInternalinsrc/Game/Properties/AssemblyInfo.csat the decompile root's HEAD. - Old: the version every baseline carrier states, and there are three — the shipped skills'
Verified against game versionlines,docs/research/'s**Baseline.**paragraphs, and theVersionInternal("<version> …")strings those paragraphs quote.grep -rho 'Verified against game version [0-9].*' plugins | sort -ureaches only the first;grep -rn '^\*\*Baseline\.\*\*' docs/researchandgrep -rn 'VersionInternal(' docs pluginsreach the other two. All three must name one version; two means a previous sweep never closed, and resuming it comes first.
Equal versions mean nothing to sweep. Say so and stop.
2. Build or resume the plan
The plan lives at .scratch/game-update-<new>/plan.md, one checkbox per step. It exists so a compaction loses nothing: the checked boxes are where the sweep is, and the skill invoked over an existing plan resumes at the first unchecked step.
One invocation does one thing: build the plan, or work one step of it. Then report the step in two lines and end the turn, so the user can compact before invoking the skill for the next step. Within the step, track its actions in the harness's task list — section 3's seven for a cluster — while the plan's checkboxes stay the record a compaction keeps.
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.

cs2-game-update is a skill published in the GitHub repository CitiesSkylinesModding/agents-plugins (5 stars, last pushed today), licensed MIT. It adds 52 tokens to every session and 3,509 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 2026-09-20.
