Codex Session Blogger

Overview

Use this skill to transform Codex session work into a technical article with a clear thesis, practical details, and reader value beyond a changelog.

Use /Users/lirantal/.agents/skills/writing-style-explainer/SKILL.md as the baseline writing style. If available, read its referenced assets/writing-style.json before drafting and apply its guidance on explainer structure, inline links, evidence, validation, trade-offs, FAQ depth, and no terminal references section.

Workflow

1. Reconstruct the session outcome.

   • Identify the original goal, constraints, major decisions, files changed, commands run, tests or checks performed, failures encountered, and the final result.
   • Prefer evidence from the conversation, local diffs, test output, commit history, issue/PR context, and source files over memory.
   • Ask the user only when a missing fact would change the article's claim, publish target, or disclosure risk.

2. Choose the publish target.

   • Use nodejs-security.com/blog when the session is primarily about Node.js security, web security, dependency or supply-chain security, npm/pnpm package risk, secure CI/CD, vulnerability research, permission models, sandboxing, exploitability, or defensive patterns for JavaScript systems.
   • Use lirantal.com/blog for agentic development, Codex workflows, developer tooling, architecture, debugging stories, general JavaScript/Node.js engineering, open source maintenance, productivity, or broader software engineering lessons.
   • If both apply, prefer nodejs-security.com/blog only when the security lesson is the main reader payoff.

3. Extract the article angle.

   • Convert the session from “what changed” into “what readers can learn or apply.”
   • Look for: a surprising failure mode, a trade-off, a useful debugging path, a reproducible workflow, a security implication, a design decision, a validation technique, or a reusable agentic development pattern.
   • Avoid writing a diary of the session. The work session is raw material; the post should stand on its own for readers who were not present.

4. Build the article brief before drafting.

   • Publish target and rationale.
   • Working title, slug, one-sentence thesis, and 2-3 sentence abstract.
   • Primary audience and reader promise, phrased as editorial guidance rather than an opening paragraph.
   • Source material used: session notes, diffs, commands, docs, issues, PRs, or external references.
   • Disclosure boundaries: anything private, speculative, sensitive, or not yet publishable.

5. Draft in the explainer style.

   • Lead with the thesis, the problem, and why it matters now.
   • Show enough implementation detail for an experienced developer to trust the lesson.
   • Include mechanisms, trade-offs, validation steps, and concrete examples.
   • Use descriptive inline links to canonical docs, specifications, repos, or prior posts where each topic is introduced.
   • Do not add a terminal ## References, bibliography, or link dump.

6. Close with practical next steps.

   • Prefer 3-5 concrete actions readers can take in their own projects.
   • Include GitHub and X/Twitter CTAs when they fit the article naturally.
   • For security posts, include detection, mitigation, or verification steps before broad calls to action.

Session Mining Checklist

Gather these facts when they exist:

• Problem: what was broken, unclear, risky, slow, or worth improving.
• Constraint: what made the work non-trivial.
• Decision: which approach won and which alternatives were rejected.
• Mechanism: how the solution works internally.
• Evidence: tests, commands, screenshots, benchmark numbers, reproduction steps, or source links.
• Failure: an error, false start, misleading clue, or edge case that teaches something.
• Generalization: what transfers to other projects or teams.
• Boundary: what remains unknown, not covered, or not safe to claim.

Article Shapes

Choose the shape that matches the session:

• Explainer from implementation: use when a concrete code change reveals a broader concept. Structure: thesis, background, mechanism, implementation details, trade-offs, validation, limitations, FAQ, next steps.
• Debugging narrative: use when the interesting part is diagnosis. Structure: symptom, failed hypotheses, turning point, root cause, fix, verification, what to monitor next time.
• Agentic workflow post: use when the lesson is about working with Codex or agents. Structure: task framing, context gathering, decision points, agent/human handoffs, verification, reusable workflow.
• Security write-up: use when the work involves exploitability, hardening, dependency risk, CI/CD risk, or secure defaults. Structure: threat model, vulnerable pattern, mechanism, safe reproduction, mitigation, detection, trade-offs, next steps.
• Tooling or DX guide: use when the work improves developer workflows. Structure: pain point, design goals, workflow, implementation, adoption path, edge cases, validation.

Editorial Rules

• Make the reader payoff explicit early: what a developer can understand, avoid, build, or measure after reading.
• Preserve technical specificity. Include filenames, APIs, commands, config snippets, error messages, and version constraints when they matter.
• Do not publish private absolute paths, secrets, tokens, unpublished vulnerabilities, private customer details, internal URLs, or repository details the user did not make public.
• Replace session-local phrasing like “we did this earlier” with article-native context.
• Keep uncertainty visible. Use “in this implementation,” “for this repository,” or “under these constraints” when the claim is not universal.
• Prefer compact, runnable examples over long code dumps.
• Include validation commands with expected output or interpretation when possible.
• Avoid hype about agents. Show where Codex helped, where human judgment mattered, and how the result was verified.

Output Contract

Unless the user asks for a different format, produce:

1. Article Brief with publish target, title, slug, thesis, abstract, tags, and disclosure notes.
2. Draft in Markdown suitable for the chosen blog.
3. Inline Link Checklist listing at least three planned or included canonical inline links, without creating a references section in the draft.
4. Verification Notes summarizing which claims came from session evidence and which still need confirmation.

If the user asks for only highlights, produce the brief and a structured outline instead of a full draft.
