ccs-reproducibility

ccs-reproducibility is a skill for Claude Code from brycewang-stanford/Awesome-Journal-Skills. It costs 58 tokens per session (716 once invoked), scanned A, original, MIT.

A guide to making an ACM CCS security paper's claims checkable by other researchers. Reproducibility means giving enough information for someone else to repeat an experiment, attack, measurement, or evaluation.

In plain words
What is it for?
Use it to document exploit steps, defence overhead, measurement methods, datasets, environments, versions, and partial or redacted research artifacts.
Why use it?
It connects each claim to evidence and exposes missing details such as versions, settings, resource limits, hardware, or measurement bias. It also explains how to be transparent when security, licensing, or safety prevents full sharing.

About the project

Awesome Journal Skills is a collection of agent skill packs tailored to hundreds of academic journals across fields including economics, social science, medicine, science, and engineering. Researchers use the packs for tasks such as choosing topics, designing empirical strategies, preparing tables and figures, submitting papers, and responding to reviewers. The catalogue entries are the project's journal-specific skills and related plugins.

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

ccs-reproducibility 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 12d 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.

CCS Reproducibility

Use this before submission and again before the artifact-evaluation deadline. Reopen the current CFP and call for artifacts to confirm what availability statement and packaging CCS expects this cycle.

Evidence map

  • Map each security claim — every attack, defense guarantee, and measurement result — to a verifiable location: a script, a config, a dataset, a proof, or a logged run.
  • For attacks, record the target's exact version and configuration, the attacker's resource budget, and the sequence of steps that reproduce the exploit.
  • For defenses, record the workload, the overhead-measurement method, the hardware, and the adaptive attacker used, so the cost-versus-security tradeoff can be rechecked.
  • For measurements, document the vantage point, the collection window, the sampling frame, known blind spots, and the ground-truth validation.
  • When artifacts cannot be shared — licensing, responsible disclosure, subject safety, or premature-release risk — say so explicitly and offer partial, synthetic, or redacted artifacts that still let a reader assess the methodology.

Availability-posture table

Claim type What full sharing looks like Honest fallback when sharing is blocked
Exploit against deployed software Runnable PoC plus target build Redacted PoC, disclosed-and-patched note, synthetic target
Defense with overhead numbers Instrumented build and benchmark scripts Binaries plus measurement scripts if source is proprietary
Internet-scale measurement Dataset plus collection tooling Aggregated data with subject-privacy justification for the rest
Cryptographic protocol Reference implementation and test vectors Spec plus test vectors if the implementation is embargoed

Claiming an artifact is unavailable without a reason CCS accepts (a license, a disclosure embargo, subject safety) reads as evasion; state the specific reason and offer the closest shareable substitute.

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.
