build-error-resolver

A build-error fixing agent that works across programming languages and project types. A build is the process of checking or preparing code so it can run or be packaged.

In plain words
What is it for?
Use it when a TypeScript, Python, Go, Rust, or other project fails to build or compile.
Why use it?
It identifies the project’s build system and focuses on correcting build, compile, or type errors with small changes, without redesigning the code.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add agents/earthchen/ai-assets/build-error-resolver
Clone the repo
git clone --depth 1 https://github.com/EarthChen/ai-assets

Or install earthchen-ai-assets, the plugin that ships this one along with the rest of its 19 skills, 16 agents.

Per session 73 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,473 The whole file, excluding the scripts and references it only reads on demand.
Security scan C 1 finding. Scan, not verified.
Origin unknown No closer match found in the catalogue.
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 C, and why

build-error-resolver scanned grade C with 1 finding 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 2d ago.

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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

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.

build-error-resolver is an agent published in the GitHub repository EarthChen/ai-assets (2 stars, last pushed 7d ago), with no licence file. It adds 73 tokens to every session and 1,473 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
