What it does

Defold Project Build is an agent skill from selimanac/defold-astar. Builds the project using the running Defold editor, returns build errors, and launches the game if build succeeds.

Its SKILL.md is about 730 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 Game Development. It works with PowerShell, Linux and macOS. The repository describes itself as: Pathfinder and A solver (astar or a-star) native extension for Defold Engine build on MicroPather.

When your agent uses it

  • Game Development work in your project

Example prompts

  • “Use the defold-project-build skill to build the project using the running Defold editor, returns build errors, and launches the game if build succeeds”
  • “/defold-project-build”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Read the port from .internal/editor.port.
  2. POST to /command/build.
  3. If the build fails, report all issues with file paths, line numbers, and messages.
  4. If the build succeeds, the game launches automatically. Check /console for runtime logs if needed.

What it can do on your machine

Read from SKILL.md and the folder at commit 1471c54. 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

    Shell commands in SKILL.md call:

    • curl

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

  • Network

    No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

    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

Defold Project Build loads about 727 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 256 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~727

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 256 words (~727 tokens).

“Build and run a Defold project by sending HTTP requests to the running Defold editor.”
