  • Modifying VPK-related Rust code

What it does

Vpk Manifest Hygiene is an agent skill from deadlock-mod-manager/deadlock-mod-manager. Enforce VPK manifest updates whenever VPK files are created, moved, renamed, enabled, disabled, or deleted. Use when modifying VPK-related Rust code, touching vpkmanager, manager.rs, mods.rs, profiles.rs, or any code that mutates the addons directory. Prevents state drift between on-disk VPKs and the .dmm.json manifest.

Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. It works with Rust. The repository describes itself as: A mod manager for the Valve game Deadlock. The licence is GPL-3.0.

When your agent uses it

  • Modifying VPK-related Rust code
  • Touching vpkmanager
  • Any code that mutates the addons directory

Example prompts

  • “/vpk-manifest-hygiene”

What it can do on your machine

Read from SKILL.md and the folder at commit cf1c98a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Vpk Manifest Hygiene loads about 704 tokens when it runs. Until then it costs about 86 tokens; SKILL.md has 249 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~86
When it runs · the whole SKILL.md, loaded when a task matches
~704

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

VPK Manifest Hygiene

Every mutation to VPK files on disk must be followed by a corresponding update to the ProfileVpkManifest (.dmm.json). Skipping this causes state drift: the manifest no longer reflects reality, leading to ghost mods, missing mods, and broken enable/disable cycles.

The Manifest

  • File: .dmm.json inside the profile's addons directory
  • Struct: ProfileVpkManifest in apps/desktop/src-tauri/src/mod_manager/vpk_manifest.rs
  • Tracks per-mod: enabled, current_vpks, disabled_vpks, original_vpk_names, order

The Rule

If you touch VPKs on disk, you must update and save the manifest in the same operation.

Concretely, any code path that does one of the following must call the corresponding manifest method and then manifest.save():

Disk operationManifest call
Install / enable VPKsmanifest.mark_enabled(mod_id, current_vpks, original_vpk_names, order)
Disable VPKs (prefix-rename)manifest.mark_disabled(mod_id, disabled_vpks, original_vpk_names)
Uninstall / delete VPKsmanifest.remove_mod(mod_id)
Reorder VPKsUpdate order via mark_enabled for affected mods
Replace / swap VPK filesmark_enabled or mark_disabled depending on final state

Existing Patterns to Follow

Look at the current call sites for reference:

  • manager.rs — enable_mod, disable_mod, uninstall_mod, reorder_mods, replace_vpk_files
  • mods.rs — persist_analyzed_mod, swap_mod_options, switch_download_variant
  • profiles.rs — import_profile

Every one of these loads the manifest, mutates it, and saves it atomically (write-to-tmp then rename). Follow the same pattern.

Checklist for Code Review

When reviewing or writing code that touches VPK files:

  • Manifest is loaded before disk mutations begin
  • Every disk mutation has a matching manifest update
  • manifest.save() is called after all mutations complete
  • Error paths do not leave the manifest out of sync (save before early returns if partial work was done)
  • No new VPK disk operations were added without manifest calls
