DevVerse-SWE-Blog: Skill for Codex

.agents/skills/devverse-validate/SKILL.md

devverse-validate is a skill for Codex from hoangsonww/DevVerse-SWE-Blog. It costs 32 tokens per session (274 once invoked), scanned A, original, MIT.

A repository-specific validation checklist for DevVerse changes. It selects checks such as tests, TypeScript checking, content validation, and builds based on which files were changed.

In plain words
What is it for?
Use it after changing DevVerse content, pages, routes, components, configuration, or libraries. It tells you which commands to run and how to report passed, failed, and skipped checks.
Why use it?
It avoids running unsuitable or destructive checks and makes the validation result explicit. It also records failures caused by the environment separately from likely code problems.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is hoangsonww/DevVerse-SWE-Blog's own configuration. It tells Codex how to work on DevVerse-SWE-Blog itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything DevVerse-SWE-Blog configures →

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

devverse-validate 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 yesterday.

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

DevVerse Validation Workflow

  1. Inspect the current diff first. Use git status --short and git diff --name-only.

  2. Read the validation matrix before running commands. @references/validation-matrix.md

  3. Choose the smallest useful set of validations that matches the touched files.

  4. Never use npm run lint as a read-only validation step. It runs Prettier write mode in this repository.

  5. Prefer the constrained-environment Jest commands when needed. Use env JEST_USE_WATCHMAN=0 npm test -- --runInBand --watchman=false.

  6. Run python3 scripts/check_content_contract.py for article changes.

  7. Run npx tsc --noEmit --pretty false for TypeScript, route, component, or library changes.

  8. Run npm run build for page, layout, config, or global styling changes when it is worth the extra cost. If it fails because of Google font fetching, report that as an environment limitation unless there is evidence of a code regression.

  9. Report exactly what ran, what passed, what failed, and what was skipped.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
