concourse-tactics

concourse-tactics is a skill for Claude Code, Codex from wgpsec/AboutSecurity. It costs 119 tokens per session (3,276 once invoked), scanned A, original, no licence file.

A security-testing guide for Concourse CI, a system that runs automated build and deployment pipelines. It covers ways to inspect and attack exposed Concourse servers, pipelines, workers, and stored credentials.

In plain words
What is it for?
Use it to test Concourse APIs, Fly CLI access, pipeline variables, build logs, resource credentials, task scripts, workers, and pipeline persistence.
Why use it?
It helps security testers assess whether a Concourse setup allows unauthorised access, secret theft, malicious job changes, or escape from its containers.

SkillSpector: 4 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Tool Misuse · line 222
    Code deploys a privileged Kubernetes workload (privileged container, hostPath mount, or host namespaces). This grants root on the node and is a node/cluster takeover vector.
    Fix: Remove privileged, hostPath, and host-namespace settings from workloads. Use a least-privilege securityContext, drop capabilities, and avoid mounting the host filesystem.

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

concourse-tactics scanned grade A with 1 finding 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 4d 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.

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.
