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 | $0.00031 | $0.00713 |
| Opus 5 | $0.00015 | $0.00357 |
| Sonnet 5 | $0.00006 | $0.00143 |
| Haiku 4.5 | $0.00003 | $0.00071 |
Grade A, and why
save-plan 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 8d 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:
-
Parse the plan name from the user's message. If they wrote
/save-plan setup-2d-scene, the name issetup-2d-scene. If no argument was provided, ask viaAskUserQuestion:- "What should this plan be called?" (free-text)
-
Validate the name: lowercase ASCII letters, digits, and hyphens only; must start with a letter or digit; 1–64 characters. If invalid, explain why and re-ask via
AskUserQuestionin the same turn. -
Ask the user where to get the plan content via
AskUserQuestion. Use this exact question and these three options:Question: "Where should I get the plan content for
<name>?"Option A — label: "Use the plan from our conversation" description: "I just shared a plan above and want to save that one."
Option B — label: "I'll paste the plan content" description: "Provide the plan as free text in the answer."
Option C — label: "Cancel" description: "Don't save anything."
If the user picks A: look at the most recent assistant message in this conversation that resembles a plan (markdown headers, numbered sections, structured outline, etc.) and use its full body verbatim. If there's no clear plan candidate in recent history, re-ask with only options B and C.
If the user picks B: use whatever they provide as the "Other (specify)" free text as the plan body verbatim.
If the user picks C: respond "Cancelled." and stop.
-
Compose a one-line description (≤80 characters) summarizing the plan. Goes into the YAML frontmatter so the Plans tab list can show it next to the name.
-
Resolve the auto-suffixed filename at
ProjectSettings/GameDeck/plans/<name>.md(relative to cwd, which isUNITY_PROJECT_PATH). Use theGlobtool to check existence:- First try
<name>.md - If it exists, try
<name>-2.md,<name>-3.md, ..., up to<name>-99.md - Pick the first slot that doesn't exist. If all 99 are taken, tell the user to delete some plans with that prefix first and stop.
- First try
-
Write the file using the
Writetool. The body must be:--- description: <one-line summary from step 4> --- <plan body from step 3, verbatim>Don't reformat the plan body — preserve whatever structure it had.
-
Confirm to the user with the actual filename used:
- No collision: "Saved as
<name>.md." - With suffix: "Saved as
<name>-N.md(a plan named<name>already existed, so I bumped the suffix)."
- No collision: "Saved as
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.

save-plan is a skill published in the GitHub repository RamonBedin/mcp-game-deck (6 stars, last pushed 2mo ago), licensed MIT. It adds 31 tokens to every session and 713 once invoked, about $0.0002 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.
