oss-second-contribution

oss-second-contribution is a skill for Claude Code, Codex from chiruu12/OSS-Skills. It costs 84 tokens per session (2,245 once invoked), scanned A, original, MIT.

A guide for planning your second and third contributions to an open-source project after your first pull request (a proposed code change) is merged.

In plain words
What is it for?
Use it to build relationships, choose increasingly challenging work, and plan continued participation in a project.
Why use it?
It helps you move from a one-time contribution to regular involvement instead of choosing issues at random or losing contact with project maintainers.

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

oss-second-contribution 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 9d 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.

Second Contribution

Your first PR got merged. Now what? Most contributors disappear here. This skill covers the transition from "someone who submitted a PR once" to "recognized contributor" — through deliberate relationship building, progressive challenge escalation, and sustained presence.

Purpose

One merged PR makes you a contributor. Three makes you recognized. Ten makes you trusted. But this isn't about counting PRs — it's about building a relationship with the project and its maintainers. Each contribution should be harder than the last, teach you something new, and demonstrate growing understanding of the project. This skill helps you plan that trajectory instead of randomly picking issues.

When to Use

  • Your first PR was merged and you want to continue contributing
  • You want to transition from occasional contributor to regular
  • You're planning sustained involvement in a project (e.g., for GSoC, career growth)
  • NOT for your first contribution — use oss-find-issueoss-prep-to-contributeoss-contribute
  • NOT if your first PR was rejected — reflect on the feedback first

Prerequisites

  • At least one PR merged in the target repo
  • Understanding of the repo's contribution workflow (from first contribution)
  • gh CLI authenticated

Process

1. Reflect on the first contribution

Before planning the next one, learn from the last one.

# Review your merged PR
gh pr list -R {owner}/{repo} --state merged --author @me --json number,title,mergedAt,reviews,comments

# Read the review comments — what did the maintainer catch?
gh pr view {number} -R {owner}/{repo} --json reviews,comments

Answer honestly:

  • What went well? What was harder than expected?
  • What feedback did the maintainer give? (Review comments reveal what they care about)
  • How long did the review take? (Fast review = maintainer trusts the work)
  • Did you enjoy working in this codebase? (Sustained contribution requires genuine interest)

2. Assess the relationship

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.
