oss-copilot

oss-copilot is a skill for Claude Code, Codex from RudraDudhat2509/claude-skills. It costs 119 tokens per session (1,314 once invoked), scanned A, original, MIT.

A guided assistant for contributing to open-source software, meaning publicly developed code that others can inspect and improve. It focuses on finding a suitable issue, choosing one, implementing a change, and preparing a pull request.

In plain words
What is it for?
Use it to find current GitHub issues, choose a repository and issue, understand the codebase, implement a fix, prepare a pull request, and update contribution logs.
Why use it?
It turns an open-source contribution into a structured process instead of leaving you to search for a project and work out the contribution steps alone. It also keeps a record of completed sessions.

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-copilot 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 11d 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.

OSS Co-Pilot

Rudra's end-to-end OSS contribution assistant. Primary niche: LLM security — agentic attack surfaces (MCP tool poisoning, agent memory poisoning, multi-agent attack chains). Expanded scope: any repo that builds job-readiness for target companies (Portkey.ai, Langfuse, Arize AI, Palantir, Scale AI) — including LLM observability, eval frameworks, agent orchestration, production AI infrastructure, and agentic backend tooling. Target: build a visible, technically credible OSS track record before graduation (2028).

Workflow

Three phases, always in this order:

Phase 1 → Discover — Search GitHub for the single best issue to work on right now.
Phase 2 → Pick — Present one recommendation with full context. Rudra confirms or asks for another.
Phase 3 → Execute — Full session: orient → env check → explain codebase → build → pre-PR checklist → post-push.

At session end: auto-update oss/CLAUDE.md status table + append to session_log.md.


Phase 1: Discover

Search GitHub fresh every session — do NOT rely on the tracked repo list in oss/CLAUDE.md.

Run multiple gh search issues queries in parallel — see references/issue-search.md for the full query list and high-value repo table.

Quick pre-filter (drop anything that fails these before spawning agents):

  1. Issue is open
  2. Repo has been active in the last 6 months
  3. Not labeled closed, duplicate, wontfix

For every candidate that passes the pre-filter, spawn one Issue Verification Agent per candidate (run in parallel). Each agent does a 4-layer check:

  • Layer 1: assignee + labels
  • Layer 2: full comment scan for claiming language, code snippets, bot assignments
  • Layer 3: linked PRs (open + merged) + GitHub timeline cross-references
  • Layer 4: commit history scan + spot-check if the feature/fix already exists in the codebase

The agent returns: VERDICT: CLEAR / CLAIMED / UNCERTAIN with a one-line reason.

Full agent prompt and all gh commands are in references/issue-search.md → Issue Verification Agent.

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.
