Triages findings from a Strix pentest by severity, fixes each root cause with a minimal change, and re-runs Strix to confirm the exploit no longer works.

usestrix/strix

Investigates TiDB plan or test-result diffs that the change does not explain, ruling out failpoint setup and merge effects before expected outputs are updated.

pingcap/tidb

Diagnoses surprising LoopX behavior, such as stale recommendations or tiny progress, assigns it to the responsible layer and repairs it at the lowest durable level.

loopx-project/loopx

Guided reverse engineering workflow for binaries, firmware, mobile apps, scripts, document samples, protocol captures, and unknown artifacts.

lingbol088-spec/reverse-flow-skill

Fix or implement a tracker issue end to end from a single command — takes an issue id or a plain problem description (filed first via om-prepare-issue), classifies, then drives the bug autofix chain…

go-musicfox/go-musicfox

Diagnoses where an agent failed across runs and turns the findings into new skills, system prompt patches and knowledge entries, using the A-Evolve loop.

aiming-lab/AutoResearchClaw

Applies a four-phase debugging routine that finds the root cause of a bug or failing test before any fix is written.

ChrisWiles/claude-code-showcase

Applies a stop-the-line rule and a step-by-step triage when tests fail, builds break or something stops working, aiming at the root cause instead of guesses.

addyosmani/agent-skills

Investigates past Kubernetes incidents from Kubeshark traffic snapshots: takes captures, dissects API calls, extracts PCAPs and compares traffic over time.

kubeshark/kubeshark

Diagnoses a failed GreptimeDB fuzz CI job by pulling its GitHub Actions logs and fuzz artifacts, then matching the evidence to the local source code.

GreptimeTeam/greptimedb

Master systematic debugging techniques, profiling tools, and root cause analysis to efficiently track down bugs across any codebase or technology stack.

sangrokjung/claude-forge

Investigates a failed Opik end-to-end test from CI, TestOps or a local run, decides regression versus flake, and proposes a fix without editing tests.

comet-ml/opik

Debugging guide for Extempore covering its three layers, compilation paths, startup sequence and the batch, eval and interactive modes used to isolate JIT problems.

digego/extempore

Conduct evidence-backed Happier code, plan-completeness, session, worktree, feature, commit, branch, PR, codebase, and release-readiness reviews with affected-corridor analysis, high-confidence…

happier-dev/happier

Pushes an agent to keep verifying and changing approach after repeated failures, using a diagnosis line, evidence-based completion and confirmation before risky edits.

tanweai/pua

Condensed debugging method and tool recipes for Unix, Python and PyTorch programs: crashes, hangs, segfaults, wrong output, CUDA OOM, NaN values and slowness.

stas00/the-art-of-debugging

A harness that makes Opus (or any Claude model) behave like Fable — it enforces seeing a task through to the end, with evidence and verification, as procedure.

fivetaku/fablize

Systematic evidence-based debugging using runtime logs. An agent skill from millionco/expect.

millionco/expect

Fixes an OpenROAD bug from a GitHub issue or error code: finds the root cause, implements the fix, adds a regression test and prepares a signed-off commit.

The-OpenROAD-Project/OpenROAD

Write the canonical engineering record of a fixed bug — root cause, mechanism, fix, validation, and how it slipped through.

thananon/9arm-skills

A skill your agent uses when asked to run Design Error Detection (quick defect scan), find design errors in a Simulink model, perform root cause analysis on DED findings, fix division-by-zero…

Walks through open Sentry issues for the tooll3 project, latest first, proposing a fix for each and committing them one at a time with your review between.

Researches code with evidence: traces callers, imports and cross-repo links, diagnoses failures and reports findings with exact file and line references and a confidence label.

bgauryy/octocode

Triage failing GitHub PR checks: list failures with gh, fetch capped Actions logs, skip non-Actions checks, and summarize root cause.
