ai-agent-session-center: Skill for Codex

.agents/skills/electron-build/SKILL.md

electron-build is a skill for Codex from coding-by-feng/ai-agent-session-center. It costs 48 tokens per session (359 once invoked), scanned A, original, MIT.

A build and verification workflow for the macOS Electron app and its DMG and ZIP installers. It checks the repository instructions, builds the current version, and verifies that the expected files exist.

In plain words
What is it for?
Use it to package the Electron app, troubleshoot the first actionable build error, confirm installer sizes, and calculate SHA-256 checksums.
Why use it?
It provides a repeatable way to catch build failures and missing distributable files before handing the app to someone else. It preserves unrelated local changes and does not publish or commit anything.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: mentions CLAUDE.md; installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is coding-by-feng/ai-agent-session-center's own configuration. It tells Codex how to work on ai-agent-session-center 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 ai-agent-session-center 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

electron-build 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.

What it actually says

Build Electron Distributables

Build the Electron app from the repository root and verify the versioned macOS artifacts. Do not commit, push, tag, or publish as part of this skill.

Workflow

  1. Resolve the Git root and read the applicable AGENTS.md and CLAUDE.md.
  2. Inspect git status --short and preserve every unrelated local change.
  3. Confirm package.json defines electron:build and read its current version.
  4. Run npm run electron:build and stream the output.
  5. If the build fails, diagnose the first actionable error. Apply only a narrow, in-scope fix that does not overwrite existing work, then rerun the smallest relevant check before retrying the build. Report the blocker instead when a safe fix needs user direction, credentials, signing access, or a broader behavior change.
  6. Verify that these non-empty artifacts exist for the package version:
    • dist/AI Agent Session Center-<version>-arm64.dmg
    • dist/AI Agent Session Center-<version>-arm64-mac.zip
  7. Report success or failure, artifact paths and sizes, and any source changes made while resolving a build failure. Include SHA-256 checksums when the artifacts may be handed off or uploaded.

Do not treat an exit code of zero as sufficient if either expected artifact is missing or empty.

Files

What ships with it

1 file 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.
