circleci

circleci is a skill for Claude Code, Codex from G1Joshi/Agent-Skills. It costs 39 tokens per session (1,278 once invoked), scanned A, original, MIT.

A cloud service for automatically running build and test pipelines when code changes. CI means checking code continuously, while CD covers preparing or delivering those changes.

In plain words
What is it for?
Use it to define build-and-test workflows, parallelise test runs, install dependencies, and conditionally run jobs for changed parts of a repository.
Why use it?
It helps teams run checks consistently, split tests across workers, reuse shared configuration, and avoid running unrelated pipeline steps in a monorepo, which is a repository containing multiple projects.

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

circleci 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 22d 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.

CircleCI

CircleCI is a continuous integration and delivery platform emphasizing pipeline parallelism, reusable configuration Orbs, and deterministic build environments.

When to Use

  • High-Velocity Cloud CI/CD Pipelines: Automating builds, tests, and deployments with Docker, Machine, and macOS executors.
  • Reusable Pipeline Architecture with Orbs: Sharing validated workflows using certified CircleCI Orbs (AWS, Slack, Docker).
  • Test Splitting & Parallelism: Accelerating slow test suites across dozens of concurrent execution containers.
  • Complex Multi-Stage Workflows: Approval gates, scheduled nightlies, and matrix build pipelines.

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.

It adds 39 tokens to every session and 1,278 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
