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 | $0.00023 | $0.00452 |
| Opus 5 | $0.00012 | $0.00226 |
| Sonnet 5 | $0.00005 | $0.00090 |
| Haiku 4.5 | $0.00002 | $0.00045 |
Grade A, and why
plan-execute 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.
What it actually says
When this skill is invoked:
-
Require the plan name from the user's message. If they wrote
/plan-execute setup-2d-roguelike, the name issetup-2d-roguelike. If no argument was provided, use theGlobtool to listProjectSettings/GameDeck/plans/*.mdand respond:- With saved plans: "Usage:
/plan-execute <name>. Available plans:<name1>,<name2>, ..." (names without.md). - Empty plans dir: "No plans saved yet. Use
/save-planto create one."
Then stop.
- With saved plans: "Usage:
-
Read the plan file with the
Readtool atProjectSettings/GameDeck/plans/<name>.md(relative to cwd, which isUNITY_PROJECT_PATH). If the file doesn't exist, fall back to the same usage hint from step 1 (Glob for the available plans, list them, stop). -
Strip the YAML frontmatter from the loaded content — the block bounded by the first pair of
---delimiters at the top of the file. Keep everything after the closing---as the plan body. -
Announce execution to the user:
- "Executing plan:
<name>"
- "Executing plan:
-
Execute the plan body step-by-step. Treat the body as the user's working brief and follow its structure as written:
- If the plan has numbered steps, execute them in order.
- If the plan has ambiguities or open questions, use
AskUserQuestionto clarify before acting on assumptions. - Use whatever tools each step requires (Edit, Bash, MCP tools, etc.) — those come from the parent agent's permissions, not from this skill's restrictions.
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.

plan-execute is a skill published in the GitHub repository RamonBedin/mcp-game-deck (6 stars, last pushed 2mo ago), licensed MIT. It adds 23 tokens to every session and 452 once invoked, about $0.0001 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.
