Codebase Blog: Technical Blog Generation from Audit Results

Role Detection (READ THIS FIRST -- MANDATORY)

Check your initial prompt. If it contains the literal string "Use the codebase-blog skill", then:

YOU ARE THE EXECUTOR. Follow these rules:

1. SKIP the "Execution Protocol" section below -- it is for the orchestrator, not you.
2. Read the pattern at ../../PATTERN.md relative to this SKILL.md, and follow it step by step.
3. ABSOLUTE PROHIBITION: Do NOT run csa run, csa review, csa debate, or ANY csa command. You must perform the work DIRECTLY. Running any csa command causes infinite recursion.

Only if you are the main agent (Claude Code / human user):

• You are the orchestrator. Follow the "Execution Protocol" steps below.

Purpose

Generate a series of technical blog posts from completed codebase-audit results. Each audited module gets a blog post explaining what it does, how it works, key design decisions, and security considerations drawn from its audit report.

Blogs are generated bottom-up (leaf dependencies first) so that each post can reference and link to its dependency blogs, creating a cohesive reading path through the codebase architecture.

Requires a prior codebase-audit run -- this pattern consumes audit results, it does not perform audits.

Execution Protocol (ORCHESTRATOR ONLY)

Prerequisites

• A codebase-audit must have been completed (at least some modules with status generated)
• csa audit status --filter generated must return non-empty results

Quick Start

csa run --sa-mode true --skill codebase-blog "Generate technical blogs for all audited modules in English"

Or with specific parameters:

csa run --sa-mode true --skill codebase-blog "Blog src/executor/ modules --language Chinese --style tutorial"

SA Mode Propagation (MANDATORY)

When operating under SA mode (e.g., dispatched by /sa or any autonomous workflow), ALL csa invocations MUST include --sa-mode true. This includes csa run, csa review, csa debate, and any other execution commands. Omitting --sa-mode at root depth causes a hard error; passing false when the caller is in SA mode breaks prompt-guard propagation.

Step-by-Step

1. Check prerequisites: Verify csa audit status --filter generated returns audited modules.
2. Get work queue: csa audit status --format json --order topo --filter generated -- filter to entries where blog_exists is false/null.
3. Prepare output: Create ${MIRROR_DIR} directory (default: ./drafts/blog/) mirroring source structure.
4. Per-module blog (bottom-up):
   • Read the audit report from ./drafts/security-audit/${path}.audit.md
   • Read the source file
   • Load prior dependency blog posts as narrative context
   • Generate blog post in ${BLOG_LANGUAGE} with ${BLOG_STYLE} conventions
   • Write to ${MIRROR_DIR}/${path}.md
   • Update manifest: csa audit update <file> --blog-path <blog_path>
5. Generate index: Create ${MIRROR_DIR}/INDEX.md linking all blogs in topological order.

Resumability

This pattern is fully resumable. If interrupted:

• csa audit status --format json --filter generated with blog_exists=false shows remaining work
• Already-blogged modules are skipped (manifest tracks blog paths)
• Re-run the same command to continue from where it left off

Example Usage

Command	Effect
/codebase-blog	Blog all audited modules (English, technical-deep-dive)
/codebase-blog --language Chinese	Blog all audited modules in Chinese
/codebase-blog src/executor/ --style tutorial	Tutorial-style blogs for executor modules
/codebase-blog --resume	Continue a previously interrupted blog generation

Integration

• Depends on: codebase-audit (must run first to produce audit reports)
• Depends on: csa audit CLI (status, update subcommands with --blog-path, --format json, --order topo, --filter)
• Related to: codebase-audit (produces the audit reports this pattern consumes)
• Output: ${MIRROR_DIR} directory (default: ./drafts/blog/) with per-module blog posts and INDEX.md

Done Criteria

1. All audited modules in scope have blog posts generated in ${MIRROR_DIR}.
2. Each blog post follows the structured format (Overview, Architecture, Key Implementation Details, Security Notes, Lessons Learned).
3. Blog prose is in ${BLOG_LANGUAGE} with style matching ${BLOG_STYLE}.
4. Manifest updated for each module with --blog-path (csa audit status shows blog_exists=true for all processed modules).
5. ${MIRROR_DIR}/INDEX.md generated with links to all blog posts in topological order.
6. Dependency blogs are cross-referenced where applicable.
