Automated summary

Scaffolds a new Starblaster Part (a slotted ship upgrade with Mk.1–9 scaling) following the extend-Part, slot_type, apply/unapply and PartFactory registration pattern.

Strengths

  • Specifies the apply/unapply contract with recorded deltas so swapping or removing a Part cleanly reverses its effect
  • Reminds you to register the Part in PartFactory, an easy step to miss
  • Chains verification through /ship and balance checking through the economy-sim agent
  • Points to the lighter data-author path when no new behavior code is needed

Limitations

  • Tightly coupled to the Starblaster project and its internal conventions (docs/contributing/04, CLAUDE.md)
  • Relies on external agents (part-author, economy-sim, game-design, data-author) being available
  • Assumes Godot/GDScript familiarity (scripts/weapons/SlotTypes.gd) that is not explained here
When to use it

Use it when adding a new ship upgrade that mutates player stats and requires new code.

When not to use it

Do not use it for a plain data-only .tres Part instance with no new behavior, or outside a Starblaster project.

Security analysis

Caution
Quality score82/100

The skill is a guided code-scaffolding workflow for a game project. It contains no destructive, obfuscated, or exfiltrating commands. However, it directs the agent to modify source files, run verification scripts, commit, and push to a remote—all powerful operations that justify a caution rating.

Findings
  • •Implicitly chains the /ship skill, which likely runs shell commands, git commit, and push; powerful but legitimate dev workflow.
  • •No allowed-tools declared, yet the procedure requires filesystem changes and remote push, which carries execution risk if run without oversight.
How this analysis is made

Examples

Ajouter un module de blindage
/add-part Add a new Part that increases the player's hull armor stat, slot_type SHIELD, scaling roughly +5% per mark from Mk.1 to Mk.9, mid-tier cost.
Ajouter un bonus de vitesse
/add-part Create a thruster Part that boosts ship top speed with a steep Mk scaling curve, and check the balance with economy-sim before we finalize it.
Scaffold et livraison
/add-part Scaffold a new weapon-damage Part, register it in PartFactory, then run /ship to verify and push.

name: add-part description: Scaffold a new Starblaster Part (a slotted ship upgrade with Mk.1–9 scaling). Use when adding a new upgrade that mutates player stats. Implements the extend-Part / slot_type / apply+unapply / PartFactory pattern, checks balance, and verifies. Follows docs/contributing/04 and chains the part-author / economy-sim agents.

/add-part — guided Part scaffold

Full reference: docs/contributing/04-player-parts-economy.md. Parts are how the player gets ANY stats — the ship starts at zero and Parts populate it.

Procedure

1. Gather intent

Confirm: which player stat(s) the Part affects, its slot_type (see scripts/weapons/SlotTypes.gd for the slot enum), the Mk.1–9 scaling curve (how the effect grows per mark), and roughly its cost tier. For balance judgment (is the per-Mk delta worth the price?), consult the economy-sim / game-design agents.

2. Implement via the part-author agent

The part-author agent owns this pattern:

  • Extend Part.
  • Set slot_type in _init.
  • apply(ship) — additive: add to the ship's stat AND record the delta.
  • unapply(ship) — reverse exactly that recorded delta (so swapping/removing the Part cleanly undoes it — this is why the delta is recorded, not recomputed).
  • Mk scaling via the mark multiplier.
  • Register the Part in PartFactory (else it can't be offered/equipped).

3. Verify + ship

Run the /ship skill: parse_check + headless boot (confirm the Part script compiles and the ship can equip it) + commit .uids + push + report to the user.

4. Balance pass (if it shifts the curve)

If the Part changes the power/cost curve meaningfully, run the economy-sim agent to sanity-check run economics before considering it final. Mention the relevant design docs (docs/archive/economy_2026-05-24.md, docs/archive/weapon_mk_progression_2026-05-25.md) for context.

Notes

  • For a pure data .tres Part instance with no new code, the data-author agent is the lighter path; new behavior needs part-author (code).
  • Cross-refs: docs/contributing/04, the "New Part" convention in CLAUDE.md.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/add-starblaster-part-mrwak9kr/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/add-starblaster-part-mrwak9kr' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/add-starblaster-part-mrwak9kr/download' --output '.skill-downloads/add-starblaster-part-mrwak9kr/SKILL.md.part' && mv '.skill-downloads/add-starblaster-part-mrwak9kr/SKILL.md.part' '.skill-downloads/add-starblaster-part-mrwak9kr/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

test -f '.skill-downloads/add-starblaster-part-mrwak9kr/SKILL.md' && test -s '.skill-downloads/add-starblaster-part-mrwak9kr/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/add-part' && cp -R '.skill-downloads/add-starblaster-part-mrwak9kr' '.claude/skills/add-part'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/add-starblaster-part-mrwak9kr'

openskills read 'add-starblaster-part-mrwak9kr'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/add-starblaster-part-mrwak9kr/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
