ci-cd-supply-chain

A set of security rules for continuous integration and continuous delivery (CI/CD), the automated systems that build, test, and release software.

In plain words
What is it for?
It guides the setup of restricted CI permissions, commit-pinned third-party actions, and exact dependency versions beyond the proof-of-concept stage.
Why use it?
It reduces the damage a compromised workflow or dependency could cause by limiting permissions and ensuring the exact code versions are known.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 15 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 182 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

ci-cd-supply-chain 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 2d 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.

What it actually says

CI/CD Supply Chain

TR-SEC-009 — CI pipelines run least-privilege and fully pinned

Every CI workflow declares an explicit least-privilege permissions block (default contents: read; broader scopes granted per-job with a comment stating why). Third-party CI actions are pinned to a full commit SHA, not a mutable tag, with the human-readable version in a trailing comment. Runtime dependencies past POC tier are pinned to exact versions so the audited dependency set is the set that runs. Counters MITRE ATT&CK T1195 (Supply Chain Compromise) and limits the blast radius of a compromised workflow token.

Changes

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.

ci-cd-supply-chain is a cursor rule published in the GitHub repository onesimplecode/agent-engineering-standards (3 stars, last pushed 4d ago), licensed MIT. It adds 15 tokens to every session and 182 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
