dev-contribution-quality-analysis

dev-contribution-quality-analysis is a skill for Codex from vasilyu1983/AI-Agents-public. It costs 36 tokens per session (3,180 once invoked), scanned A, original, MIT.

An analysis workflow that uses Git history and pull-request data to assess the quality of developers’ contributions. It looks at outcomes such as code churn, duplication, and test coverage rather than simply counting activity.

In plain words
What is it for?
Use it to create individual contribution reports, team comparisons, engineering scorecards, or promotion-calibration evidence from repository history.
Why use it?
It provides a more evidence-based way to compare contribution quality and evaluate engineering or AI-assistance impact.

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 A, and why

dev-contribution-quality-analysis 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 10d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/compute-code-rating.py, scripts/extract-contribution-profile.py, scripts/generate-quality-report.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Developer Contribution Quality Analysis

Objective, multi-dimensional analysis of code contribution quality from git data. Produces individual deep-dive reports and team calibration comparisons.

Modern Best Practices

  • Measure contribution quality through outcomes (churn, duplication, test coverage), not presence metrics
  • AI-assisted code is normal; score the output, not the authorship
  • GitClear Diff Delta and CodeScene Code Health are the established commit-level quality benchmarks
  • Stanford ghost engineering research claims commit content analysis predicts expert quality judgments (r=0.82); study is not peer-reviewed — apply with caution
  • Agent Trace (Cursor RFC) is an emerging vendor-neutral standard for AI attribution
  • DX Core 4 framework consolidates DORA/SPACE into a unified set of four oppositional dimensions
  • DORA 2025 itself reports AI adoption now correlates with higher throughput and a "mirror and multiplier" pattern (seven team archetypes replace prior elite/high/medium/low clusters); do not confuse it with vendor telemetry reports
  • Faros AI's 2026 "Acceleration Whiplash" telemetry report (4,000+ teams, distinct from DORA) found bugs per developer up 54% and incidents per PR up 242.7% where AI adoption outran test/review discipline — cite it as Faros, not DORA
  • GitClear Jan 2026 (2,172 developer-weeks): power AI users produced 4.2x more durable code than non-users but also showed 9x more churn — AI widened an existing performance gap and its downside, not evidence of uniform uplift
  • GitClear "The Maintainability Gap" 2026 (623M code changes) extends this: refactor/moved-code share collapsed to 3.8% YTD 2026 (13% in 2023), copy/paste 15.7% in H1 2026, error-masking constructs +47%, cross-file reuse -35% — use these as the current structural-quality benchmarks
  • Treat commits and PRs authored end-to-end by an autonomous coding agent (not just AI-assisted) as a distinct evidence class — see Known Traps
