fvtt-mcp-molten5e: Skill for Claude Code

.claude/skills/session-audit/SKILL.md

session-audit is a skill for Claude Code from Txpple/fvtt-mcp-molten5e. It costs 258 tokens per session (3,299 once invoked), scanned A, original, MIT.

A read-only review of the next game session and the wider campaign. It examines the live maps, player characters, monsters, plot notes, and available play time.

In plain words
What is it for?
Use it to check encounter difficulty, total combat workload, session length, campaign progress, and whether the planned adventure fits the available hours.
Why use it?
It helps a game master spot fights that may be too easy or too hard, too much content for one evening, or pacing problems in the campaign before play begins.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

session-audit 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (encounter-math.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Session and campaign audit

A DM who has just finished building a dungeon cannot see it. They know every room, so they cannot feel the fourth hour of it, and they have never once added up how many hit points they placed. This skill is the outside reader: it reads what is actually on the maps, does the arithmetic the DM never does, and reports what will really happen on the night. The tools own the reads; this skill owns the judgment — which axis is off, what the numbers mean, and which changes are worth making.

Numbers before opinions, and read-only throughout. Every claim in the report traces to a live read or to a stated formula. An audit that guesses is worse than no audit, because it reads as authoritative. Change nothing in the world unless the user says go.

Step 0 — ultracode, then the brief

An audit is a wide read: every PC sheet, every placed token, every magic item, the plot doc, the session history. At ordinary effort a model samples instead of sweeping, and a sampled audit is the dangerous kind — confident, tidy, and blind to the one room that breaks the night.

Ultracode state arrives in a system reminder. If it says on, say so in one line and proceed. If it says off — or nothing says either way — tell the user audits run best with it on and ask whether to enable it or go ahead anyway, then honor the answer without arguing it twice. Never guess: claiming a mode you cannot actually see is the same failure the rest of this skill exists to prevent.

Then take the brief. Ask only what you cannot read: which session, which site, the play date, and how many hours the table actually has. Assumptions the user hands you are binding — "assume Morgash takes the maul, Gren the pearl" is an instruction, not a hypothesis. If a stated assumption is factually off (they say axe, the sheet says maul), correct it in one line and carry on with their intent; do not stop to litigate it.

Step 1 — read wide, in this order

Surface Tools What you are actually after
PC sheets get-actor per PC AC, HP, saves, and whether they have Extra Attack yet
Magic items get-actor-entity on every attuned/equipped magic item the item's real mechanics
The stash get-group loot nobody is carrying — that is a finding, not background
The site list-scenes then list-tokens per scene the roster as actually placed
The monsters get-actor on the placed token id that instance's delta, not the library actor
Signature abilities get-actor-entity on multiattack + the gimmick the activity, not the name
Intent list-journals (the GM key), plot/, newest gm-notes.md what the build was supposed to be
The ground screenshot-scene on combat maps only chokepoints, approach length, sightlines

Changes

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.
