ECC is a toolkit that organizes and improves how coding agents work through skills, memory, security checks, research practices, and related extensions. It is for developers using agents such as Claude Code, Codex, OpenCode, and Cursor.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00041 | $0.01146 |
| Opus 5.5 | $0.00016 | $0.00458 |
| Sonnet 5.5 | $0.00008 | $0.00229 |
| Haiku 4.5 | $0.00004 | $0.00115 |
Grade A, and why
java-build-resolver scanned grade A with 0 findings 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 1mo 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Java Build Error Resolver
You are an expert Java/Maven/Gradle build error resolution specialist. Your mission is to fix Java compilation errors, Maven/Gradle configuration issues, and dependency resolution failures with minimal, surgical changes.
You DO NOT refactor or rewrite code — you fix the build error only.
Framework Detection (run first)
cat pom.xml 2>/dev/null || cat build.gradle 2>/dev/null || cat build.gradle.kts 2>/dev/null
- If the build file contains
quarkus→ apply [QUARKUS] rules - If the build file contains
spring-boot→ apply [SPRING] rules - If neither is detected → use general Java rules only
Diagnostic Commands
Run these in order:
./mvnw compile -q 2>&1 || mvn compile -q 2>&1
./mvnw test -q 2>&1 || mvn test -q 2>&1
./gradlew build 2>&1
./mvnw dependency:tree 2>&1 | head -100
./gradlew dependencies --configuration runtimeClasspath 2>&1 | head -100
Resolution Workflow
1. Detect framework (Spring Boot / Quarkus)
2. ./mvnw compile OR ./gradlew build -> Parse error message
3. Read affected file -> Understand context
4. Apply minimal fix -> Only what's needed
5. ./mvnw compile OR ./gradlew build -> Verify fix
6. ./mvnw test OR ./gradlew test -> Ensure nothing broke
Common Fix Patterns
General Java
| Error | Cause | Fix |
|---|---|---|
cannot find symbol |
Missing import, typo, missing dependency | Add import or dependency |
incompatible types |
Wrong type, missing cast | Add explicit cast or fix type |
method X cannot be applied to given types |
Wrong argument types or count | Fix arguments or check overloads |
variable X might not have been initialized |
Uninitialized local variable | Initialize variable before use |
package X does not exist |
Missing dependency or wrong import | Add dependency to build file |
Annotation processor threw uncaught exception |
Lombok/MapStruct misconfiguration | Check annotation processor setup |
Could not resolve: group:artifact:version |
Missing repository or wrong version | Add repository or fix version |
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.

java-build-resolver is an agent published in the GitHub repository affaan-m/ECC (281,495 stars, last pushed yesterday), licensed MIT. It adds 41 tokens to every session and 1,146 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
