feat: log MythicLib skill casts and skill teleports

[ryanbarlow97]

Summary

• Logs every MythicLib skill a player activates (MMOCore class skills, MMOItems abilities) as a command row at the caster's position: [skill] Arcane Blink (ARCANE_BLINK).
• If the skill teleports the player (cause PLUGIN or UNKNOWN) within 5 seconds, a second row is stored at the destination: [skill] Arcane Blink (ARCANE_BLINK) teleported from 0 -60 1 to 0 -59 6. Capped at five teleports per cast. Radius lookups near a base therefore show who teleported into it.
• Skills on silent triggers (timers, attacks, damage, API casts) are skipped and don't affect the teleport window. MythicLib marks click triggers as passive too, so silence is what separates automatic casts from activated ones. MMOCore and MMOItems override Skill.getTrigger() with their configured trigger.
• New lookup action a:skill (aliases skills, ability, abilities): a command lookup restricted to the [skill] prefix. f:<name> narrows it to one skill. Commands always start with /, so skill rows never match command filters. a:command still lists everything, and both use coreprotect.lookup.command.
• New config option player-skills (default true). skill added to tab completion.
• MythicLib is read through reflection and added to softdepend, so the build needs no private jar and CoreProtect runs unchanged without MythicLib. Nothing on Main that MythicLib loads after depends on CoreProtect, so there is no load-order cycle.

On Main every teleport ability (Arcane Blink, Mage Blink, Shadow Teleport) is right-click or shift-right-click. Mage Blink is a lunge, so it only gets the cast row.

Test plan

There is no test suite in this repo, so I tested on a local Paper 1.21.10 server with MythicLib 1.7.1, MythicMobs 5.13.1, a lab plugin that casts skills through the MythicLib API with a chosen trigger, and a scripted Fabric client as the player:

• SQLite (what Main and Dev use): built-in BLINK (CAST) and MythicMobs-backed ARCANE_BLINK (RIGHT_CLICK) each log a cast row and a teleport row at the destination
• TIMER and API casts log no cast row
• A COMMAND-cause teleport inside the window and a PLUGIN-cause teleport after it are not credited
• a:skill, a:skill f:arcane, a:command, r:12 a:skill and a:skill,command return the expected rows, both in game and from the console
• player-skills: true is written to an existing config with its header
• Build has no compiler warnings

📝 Summary

Summary by CodeRabbit

• New Features
  • Added optional logging of player-activated MythicLib skills, enabled by default. Eligible teleports following a skill cast may also be recorded for up to five seconds.
  • Added skill lookup and filtering with /co lookup a:skill; skill lookups reject incompatible action filters.
  • Added tab completion for the unprefixed container action.
• Documentation
  • Updated the feature overview to include skill and related teleport logging.

Walkthrough

The change adds MythicLib skill-cast logging and eligible teleport logging. It adds a player-skills configuration option and a skill lookup action with dedicated filter handling.

Changes

Skill logging and lookup

Layer / File(s)	Summary
Skill log format and queue support src/main/java/net/tfminecraft/coreprotect/model/action/SkillLog.java, src/main/java/net/tfminecraft/coreprotect/consumer/Queue.java	SkillLog formats cast and teleport messages and prepares skill lookup filters. Queue adds support for queuing a skill record at a supplied location.
MythicLib cast and teleport capture src/main/java/net/tfminecraft/coreprotect/config/Config.java, src/main/resources/plugin.yml, src/main/java/net/tfminecraft/coreprotect/listener/ListenerHandler.java, src/main/java/net/tfminecraft/coreprotect/listener/player/SkillCastListener.java, README.md	Configuration adds player-skills, enabled by default, and plugin.yml lists MythicLib as a soft dependency. Listener setup registers reflective cast handling, which queues non-silent casts and eligible teleports. The README feature description includes skill and teleport logging.
Skill lookup parsing and filters src/main/java/net/tfminecraft/coreprotect/command/parser/ActionParser.java, src/main/java/net/tfminecraft/coreprotect/command/LookupCommand.java, src/main/java/net/tfminecraft/coreprotect/command/TabHandler.java	ActionParser identifies skill-only lookups. LookupCommand applies skill filters and rejects incompatible selected actions. Tab completion adds the unprefixed container action.

Merge Risk: 🔵 Low · up to f8843

Skill logging and lookup appear to work as intended. Mixed-action skill lookups are now rejected rather than silently dropping rows. Remaining risk is minor, so the change can be merged with owner awareness.

Security Architecture Review

Security architecture risk: 🔵 Low · up to f8843

Skill lookups retain the existing command-lookup permission model. The main risk is audit accuracy: an unrelated teleport can inherit a recently activated skill’s name. The player identity and destination remain independently recorded, limiting the impact.

Retained concerns

• Low · security · inferred: Teleport audit rows present the latest skill as the cause of movement without a causal link. An unrelated PLUGIN or UNKNOWN teleport within five seconds, or overlapping casts, can produce misleading skill attribution in security investigations. The controls preserve the event’s player and destination but do not establish which skill caused it.

Security review details

Security Blast Radius

• inferred — The supported exposure is additional player skill and movement audit content within the hosting server’s enabled worlds and command-lookup access model. Misattribution is confined to eligible events for the same player during the latest cast window; it does not itself grant teleport authority, change player identity, or provide access to another server.

Security Findings and Attack Paths

• inferred — A player able to activate a skill and trigger an unrelated PLUGIN or UNKNOWN teleport within five seconds can cause that teleport event to receive the skill’s causal label. Availability of such an unrelated teleport is deployment-dependent and was not reproduced. The event’s player and coordinates are still recorded, so the supported concern is misleading audit attribution, not demonstrated impersonation or privilege escalation.

Trust Boundaries and Controls

• observed — The listener reads skill metadata from the loaded MythicLib event API and player identity from the server event. User lookup filters are narrowed through the skill prefix and forwarded with COMMAND actions to the standard query path. Raw SQL predicate enforcement was not fully hydrated, so this establishes the inspected application controls rather than complete database-boundary assurance.

Resilience and Maintainability Implications

• observed — Correlation rejects cancelled events, other teleport causes, missing worlds, and same-block moves. An atomic counter limits accepted records to five per cast. Expired state is rejected and conditionally removed on access; quitting removes the player’s state. New activated casts replace previous state, while automatic casts leave it unchanged. These are bounded correlation controls, not proof of causal linkage or crash recovery.

Hardening Proposals

• proposed — Represent time-window matches as correlated teleports rather than skill-caused teleports unless the integration can supply a causal cast identifier. This would preserve useful destination evidence without overstating attribution.

- Around line 56-58: Update LookupCommand’s skill-lookup flow to retain the
original filters separately from SkillLog.lookupFilters(argFilters). Carry both
filter sets through StandardLookupThread and the Lookup calls, applying
skill-specific filters only to command rows and original filters to chat rows in
both count and paginated paths.
