github-contribution-period-analysis

by tiangong-aiAI & Agents

Analyze one GitHub user's code contribution activity in a specified UTC time window and generate a Markdown report focused on practical contributions (authored merged PRs, PRs merged by the target user, and authored commits) across accessible public and private repositories.

GitHub Contribution Period Analysis

Core Goal

  • Build an evidence-based Markdown report for one target GitHub user in a UTC time window.
  • Focus on practical code contribution signals: merged PR and commit activity.
  • Cover both own repositories and other repositories, limited by credential access.

Workflow

  1. Prepare authentication for GitHub API access.
  2. Run scripts/github_contribution_report.py with target user and time window.
  3. Review the generated Markdown report and inspect evidence links.

Command

python3 scripts/github_contribution_report.py \
  --user <github-login> \
  --start 2026-03-01 \
  --end 2026-03-08 \
  --output /tmp/github-contribution-report.md

Output Semantics

  • Included contribution types:
    • Authored merged PRs.
    • PRs merged by the target user (maintainer merge work).
    • Authored commits.
  • Excluded activity types:
    • Comments, reviews, stars, watches, forks.
  • The report contains:
    • Scope and coverage notes.
    • Summary metrics.
    • Substantive work categories inferred from PR/commit evidence.
    • Work content highlights with representative evidence links.
    • Repository breakdown.
    • Per-repository concrete change details (for every changed repository).
    • Contribution timeline.
    • Top contribution tables.
    • Evidence appendix with PR/commit URLs.

Important Constraints

  • SSH key alone is for git transport and does not directly authorize GitHub REST API calls.
  • Private repository coverage needs authenticated API access, typically via GITHUB_TOKEN/GH_TOKEN or gh auth token.
  • GitHub Search API has a 1000-item cap per query. For very active users, split the time range and run multiple reports.

google-agents-cli-publish

google/agents-cli

This skill should be used when the user wants to "publish an agent", "publish my ADK agent", "register an agent with Gemini", "publish to Gemini" (formerly Gemini Enterprise), or needs guidance on the agents-cli publish gemini command. Also use when the user wants to "manage agents in Agent Registry", "list/update/delete registered agents", or "register an MCP server". Covers ADK vs A2A registration modes, programmatic and interactive usage, flag reference, auto-detection from deployment metadata, Agent Registry fleet management, and troubleshooting. Part of the agents-cli skills suite. Do NOT use for deployment (use google-agents-cli-deploy).

google-agents-cli-eval

google/agents-cli

This skill should be used when the user wants to "run an evaluation", "evaluate my agent", "evaluate my ADK agent", "write an eval dataset", "analyze eval failures", "compare eval results", "optimize agent", or needs guidance on the Gemini platform eval methodology and the Quality Flywheel. Covers eval metrics, dataset schema, LLM-as-judge scoring, and common failure causes. Applies to any agents-cli project, whatever framework the agent is written in. Do NOT use for agent API code patterns (ADK: use google-agents-cli-adk-code), deployment (use google-agents-cli-deploy), or project scaffolding (use google-agents-cli-scaffold).

codex-pet

prime-skills/runcomfy-agent-skills

Codex Pet generator on RunComfy. Build a Codex-compatible Codex Pet spritesheet.webp + pet.json from a single reference image, drop it into ${CODEXHOME:-$HOME/.codex}/pets/ / and Codex picks it up as a custom Codex Pet next to the 8 built-ins. This skill produces the exact Codex Pet atlas Codex expects (1536x1872 PNG/WebP, 8 cols x 9 rows, 192x208 cells, 9 animation states — idle, running-right, running-left, waving, jumping, failed, waiting, running, review). Calls OpenAI GPT Image 2 edit ONCE via the local RunComfy CLI as runcomfy run openai/gpt-image-2/edit to produce a canonical Codex Pet pose, then assembles all 9 animation rows programmatically with ImageMagick micro-transforms — no Codex Pro, no $imagegen, no OPENAIAPIKEY required, only RUNCOMFYTOKEN. Triggers on "codex pet", "create codex pet", "make codex pet", "hatch codex pet", "/hatch image", "desktop pet codex", "codex pets", "spritesheet.webp", or any explicit ask to build a custom pet for OpenAI Codex.
