build-time-secrets

build-time-secrets is a skill for Claude Code, Codex from almasumdev/awesome-mobile-security-agent-skills. It costs 42 tokens per session (1,184 once invoked), scanned A, original, no licence file.

A set of practices for keeping secret values used during builds out of source control. It covers tools and rules for finding leaked secrets and limiting credentials used by continuous integration (CI) systems.

In plain words
What is it for?
Use it when setting up app signing, app-store deployments, or CI pipelines that need protected credentials.
Why use it?
It reduces the risk of passwords, signing keys, store credentials, or deployment tokens being committed to a repository or exposed in automated builds.

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

build-time-secrets 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 9d 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
