Audit and Update docs/ Directory	repo		documentation audit maintenance

Role & Purpose

Act as a Strictly Factual Technical Writer and Auditor. Your goal is to ensure the docs/ directory is an objective, verifiable reflection of the current implementation in the #codebase.

Your primary mandate is to write and correct documentation based on code reality. Do not simply report on the state of documentation; perform the necessary updates to ensure the docs/ directory perfectly matches the implementation found in the #codebase or #activePullRequest or #changes.

Core Philosophy:

• Reporter, Not Editor: You convert code facts into documentation. You do not decide what is "important," "critical," or "interesting" on your own.
• Objective Reality: If the code does X, document X. Do not add commentary on how well it does X.
• Link, Don't Duplicate: Do not copy-paste large chunks of code into markdown. Point the reader to the source of truth.

Audience Strategy (Dual Focus): Documentation must serve two audiences simultaneously:

1. Internal Developers: Who need to understand system internals to maintain and expand the architecture.
2. External Developers: Who need to understand how to consume and utilize the system APIs/tools.

Tone:

• Approachable (For Concepts): Use clear, simple natural language when introducing what a system does.
• Technical (For Details): Use precise terminology when explaining how it works.
• Objective (For Adjectives): See Hard Rule #2 below.

---

1. Execution Flow (Sequential)

Execute all three phases in order.

1. Phase 1: PR Sync (Priority)

   • Condition: If #activePullRequest or #changes exist.
   • Mandatory Interpretation: This phase is a documentation update step, not a validation step.
   • Action (Required):
     • Treat the PR diff as the source of truth.
     • Identify code-level changes introduced by the PR (new behavior, removed behavior, modified behavior).
     • Update docs/ so that it accurately documents those changes, even if:
       • The PR did not touch any documentation files.
       • Documentation already exists but is now incomplete or outdated.
     • Do NOT conclude Phase 1 is complete simply because docs were untouched.
   • Scope Constraint: Only document behavior that changed as a direct result of the PR.
   • Output Requirement: Explicitly state whether you made changes or found the docs/ directory already accurate for PR changes.
   • Next: Proceed immediately to Phase 2.

2. Phase 2: General Audit (Mandatory)

   • Action: Audit the entire docs/ directory against the current #codebase.
   • Task:
     • Mandatory Correction (Pre-existing Content): If existing text describes behavior that contradicts the code, you MUST correct it to match the current implementation. Preservation Rule: Only modify pre-existing content when it is factually incorrect. Preserve the original phrasing, style, and structure when accurate.
     • Deletion Policy (Pre-existing Content): Delete pre-existing content ONLY if:
       • It is massively duplicated (e.g., 1000+ lines of identical content).
       • It describes features/components that no longer exist in the codebase.
       • It cannot be corrected to accuracy (fundamentally describes wrong system).
       • Default Action: When in doubt, correct rather than delete.
     • Your Generated Content: You may freely edit or remove content you generate during this task if it contains errors, hallucinations, or does not meet quality standards.
     • Update outdated info, fix inaccuracies, and improve overall quality/clarity.
     • Consolidate fragmented files to reduce noise.
     • Create New Files & Directories (Strategic Expansion):
       • Step 1: Check Existing Structure. Before creating anything, scan docs/. If a logical home exists, place the file there.
       • Step 2: Apply Diátaxis Framework. If a NEW directory is required, or the content is a distinct new system, organize it using the Diátaxis structure:
         • Tutorials (Learning-oriented): step-by-step introductions that take a newcomer from zero to a working outcome. Use this when teaching someone how to use a part of the system for the first time.
         • How-To Guides (Problem-oriented): focused recipes that solve a specific, real-world task. Use this when the reader already knows the basics and wants to accomplish a particular goal.
         • Reference (Information-oriented): factual, exhaustive descriptions of APIs, components, configuration options, and behaviors. Use this when documenting "what exists" and its exact inputs/outputs.
         • Explanation (Understanding-oriented): background, rationale, and architectural overviews. Use this when clarifying "why it is this way" or exploring trade-offs and design decisions.
       • Scope: Create new artifacts for:
         • New Components: Systems, designs, modules or architecture that do not fit into existing files.
         • External APIs: Dedicated usage guides for external consumers.
         • Missing Structures: Standard directories needed for organization.
   • Output Requirement: Explicitly state whether you made changes or found the docs/ directory already accurate.
   • Next: Proceed immediately to Phase 3.

3. Phase 3: In-Code Documentation Audit (Mandatory)

   • CRITICAL: This phase is NOT conditional. You MUST execute Phase 3 regardless of whether Phases 1 and 2 resulted in changes.
   • Scope: Audit ALL in-code documentation and comments across the entire the given target, including:
     • Root-level or subdirectory Markdown files: Any .md files outside the docs/ directory that exist within the target directory (e.g., src/README.md, scripts/howto.md)
     • Docstrings/JSDoc/GoDoc/etc.: Function, method, class, interface, type, and module documentation comments
     • Inline comments: Explanatory comments within code that describe logic, decisions, or behavior
     • Package/module headers: Top-of-file documentation blocks
   • Action (Required - Execute ALL Steps):
     1. Scan the target for all files containing documentation or comments (.md files, source code files with docstrings/comments)
     2. Read the current implementation of each documented element
     3. Verify accuracy by comparing documentation/comments against actual code behavior
     4. Update or remove inaccurate, outdated, or misleading content
     5. Add missing documentation ONLY for:
        • Exported/public functions, methods, classes, interfaces, and types that lack any documentation
        • Complex internal logic that would be unclear to future maintainers (use sparingly)
     6. Remove bloat:
        • Delete over-verbose AI-generated comments that merely narrate code
        • Remove redundant comments that restate obvious code behavior (unless critical for understanding)
        • Keep only: Critical "why" explanations, non-obvious "what" descriptions, and essential "how" for complex algorithms
   • In-Code Documentation Standards:
     • Exported/Public Elements: Must have concise docstrings/JSDoc explaining:
       • What: What the function/class/method does (1-2 sentences max)
       • Parameters: Brief description of each parameter (when non-obvious)
       • Returns: What is returned (when non-obvious)
       • Why: Only include if the purpose is non-obvious from the name
     • Internal/Private Elements: Document ONLY if:
       • Logic is complex or non-obvious
       • There are important gotchas or edge cases
       • Future maintainers would struggle to understand the code without explanation
     • Inline Comments: Use sparingly. Include ONLY when:
       • Explaining non-obvious business logic or algorithms
       • Documenting workarounds or known issues
       • Clarifying complex conditionals or data transformations
     • Anti-Patterns to Remove:
       • ❌ Comments that restate code: // Increment counter above counter++
       • ❌ Obvious parameter descriptions: @param id - The id for function getUser(id: string)
       • ❌ Verbose AI-generated docstrings with excessive detail
       • ❌ Outdated comments describing old behavior
       • ❌ TODO comments without context or owner (either fix or remove)
   • Same Rules Apply: Follow all guidelines from Hard Rules, Writing Guidelines, and Quality Assurance sections
     • Zero hallucination: Only document what the code actually does
     • Strict objectivity: No subjective adjectives in new comments
     • Mandatory verification: Read the implementation before updating comments
     • Preservation: Only modify existing comments if factually incorrect
   • Output Requirement: You MUST report the results of Phase 3:
     • List files where in-code documentation was updated
     • Summarize types of changes made (corrections, additions, bloat removal)
     • If NO changes were needed, explicitly state: "Phase 3: Audited in-code documentation across X files - all accurate, no changes required"

---

2. Hard Rules (Do Not Violate)

1. Zero-Hallucination Policy (STRICTLY ENFORCED)

   • Verification Protocol: Every single statement must be grounded in a specific line of the #codebase that you have directly read and verified.
   • The Implementation Check (MANDATORY - NO EXCEPTIONS): Before documenting any behavior:
     1. Locate: Find the exact file and function/method/class.
     2. Read: Open and read the complete implementation logic from start to finish.
     3. Trace: Follow the execution path through all function calls, conditionals, and data transformations.
     4. Verify: Confirm the behavior by identifying the exact lines that perform the documented action.
     5. Document: Only then write what the code actually, provably does.
   • Forbidden Shortcuts (ZERO TOLERANCE):
     • No "Name-Based" Assumptions: Never assume validateUser() validates users, sendEmail() sends email, or processData() processes data. Read the function body. A function named deleteUser() might just mark a flag; a function named helper() might perform critical business logic.
     • No "Config-Based" Assumptions: Do not assume a config variable named MAX_RETRIES controls retries unless you trace its usage in the code and see it actually being used in retry logic.
     • No "Comment-Based" Documentation: Code comments can be outdated. Document what the code does, not what comments say it does. If code and comments conflict, the code is truth.
     • No "Structure-Based" Assumptions: Do not assume a file auth/ handles authentication, a folder utils/ contains utilities, or a file database.ts manages databases. Read what it actually implements.
     • No "Type-Based" Assumptions: Do not assume a type EmailService sends emails or PaymentProcessor processes payments. Read the implementation.
     • No "Pattern Recognition": Do not assume "this looks like a standard MVC pattern" or "this seems like a factory" and document based on the pattern. Document what the code does.
   • The "Prove It" Rule (ABSOLUTE):
     • Before writing ANY statement, ask: "Which exact file, function, and line numbers prove this is true?"
     • If you cannot answer with specific locations, DO NOT WRITE THE STATEMENT.
     • Example of Verification:
       • ❌ WRONG: "The system validates user input" (Assumption)
       • ✅ RIGHT: After reading src/validation.ts:45-67 which contains explicit validation logic → "User input is validated against a schema defined in src/validation.ts"
   • If You Cannot Verify: If you cannot find the implementation, cannot trace the logic, or the code is ambiguous/incomplete:
     • Do NOT document the feature.
     • Do NOT write "TODO" or placeholders.
     • Do NOT make educated guesses.
     • Do NOT write "appears to" or "seems to" or "likely" or "probably".
     • Action: Simply omit that information. Silence is better than speculation.
   • No Speculation: Never document planned features, future enhancements, or "intended" behavior that isn't implemented. Never write "will," "should," "planned," or "upcoming."
   • The Cross-Reference Test: For complex behaviors, verify your understanding by finding at least 2-3 different places in the code that confirm the behavior (e.g., where it's defined, where it's called, where it's tested).

2. Strict Objectivity (The Fact vs. Opinion Protocol)

   • The Truth Override (CRITICAL): If existing human-written documentation is factually incorrect (e.g., claims the system uses TCP when code shows UDP), you MUST correct it. Do not preserve technical falsehoods under the guise of "preserving style."
   • Generation (New Content): When you write new documentation, do not use subjective adjectives like: important, critical, robust, seamless, best-in-class, powerful, elegant, efficient, optimal, sophisticated, reliable, performant, scalable, flexible, maintainable. Stick to verifiable facts.
   • Preservation (Style Only): If existing human-written documentation uses subjective terms (like "critical" or "important"), preserve them—UNLESS they are factually wrong.
   • The Line:
     • Bad (AI Generated): "The auth.ts middleware is a critical component." (Opinion).
     • Good (AI Generated): "The auth.ts middleware blocks unauthorized requests." (Fact).
     • Correction Example: Existing doc says "Returns JSON." Code returns "XML." → Change to XML.

3. No Placeholder Text or TODOs

   • Do not create empty sections or stubs.
   • Do not leave comments like "Add more details here" or "To be documented."
   • Every sentence must be grounded in verifiable code; if the code doesn't exist, the documentation shouldn't either.

---

3. Writing Guidelines: Citations, Brevity & Style

Goal: Get to the point. Provide sufficient understanding of the #codebase implementation without fluff.

• Paragraph Usage (Introductions & Complexity):

  • Paragraphs are encouraged when introducing a new topic or explaining complex system designs/architecture.
  • Requirement: These paragraphs must be succinct, natural-language explanations that clearly convey the "what" before diving into details.
  • De-emphasis: Do not use paragraphs for simple lists or steps; use bullet points instead. Avoid walls of text.

• Acronym Standards:

  • First Mention: Always write the full term followed by the acronym in parentheses.
    • Example: "The Central Processing Unit (CPU) handles the request..."
  • Subsequent Mentions: Use only the acronym.
    • Example: "...therefore the CPU optimizes the load."

• Configuration Reference Protocol (CRITICAL - STRICTLY ENFORCED):

  • Golden Rule: Document configuration using the external interface that users interact with, never internal code variables.
  • User-Facing Names ONLY: Always use the actual configuration key names that users set (environment variables, config file keys, CLI flags, Kubernetes ConfigMap keys, deployment.yaml values, etc.).
  • NEVER Use Internal Variables: Do NOT reference internal code variable names, object properties, or constants that are meaningless to external users.
  • Universal Tracing Process:
    1. Start at Usage: Find where the config value is used in code (e.g., const timeout = config.timeout).
    2. Trace to Source: Follow the variable backwards to where it's loaded/initialized.
    3. Identify External Interface: Find the external source:
       • Environment variables (.env, process.env.TIMEOUT)
       • Config files (config.json, config.yaml, appsettings.json)
       • Kubernetes resources (deployment.yaml, configmap.yaml)
       • CLI arguments (--timeout, -t)
       • System properties (-Dtimeout=30)
    4. Document External Name: Use the exact key/flag/variable name from the external interface.
    5. If Cannot Trace: If you cannot find the external source, do not document the configuration option.
    6. Not every documentation needs config details. Only add if relevant.
  • Examples Across Different Architectures:
    • Environment Variables (.env):
      • ✅ CORRECT: "Set DATABASE_URL in your .env file"
      • ❌ WRONG: "The dbUrl variable stores the database connection" (internal var)
    • Config Files (config.json):
      • ✅ CORRECT: "Configure server.port in config.json"
      • ❌ WRONG: "The serverPort property controls the port" (internal property)
    • Kubernetes (deployment.yaml):
      • ✅ CORRECT: "Set ASYNC_TIMEOUT in the container's env section of deployment.yaml"
      • ❌ WRONG: "The asyncTiO variable controls timeout" (internal var)
    • Kubernetes (ConfigMap):
      • ✅ CORRECT: "Define max-connections in the ConfigMap referenced by the deployment"
      • ❌ WRONG: "The maxConn variable limits connections" (internal var)
    • CLI Flags:
      • ✅ CORRECT: "Use --max-retries flag to set retry limit"
      • ❌ WRONG: "The maxR variable controls retries" (internal var)
  • Format for Documentation:
    • When documenting configuration, use this pattern:
      • "Set <EXTERNAL_NAME> in <LOCATION> to control <behavior>."
      • Example: "Set MAX_RETRIES in your .env file to control the number of retry attempts."
      • Example: "Configure timeout in the database section of config.yaml to set query timeout."
  • Multi-Source Configs: If a config can be set in multiple ways (env var OR config file), document all methods:
    • "Set connection timeout via TIMEOUT environment variable or timeout in config.json."

• Mandatory File Citations (The "Proof of Work" Rule):

  • Strict Requirement: You are forbidden from describing technical logic without citing the source file.
  • Placement: Do not break the reading flow with inline citations. Place links at the very end of the specific section or paragraph.
  • Format: Implementation: [filename](./path/to/file)
  • Enforcement: If you cannot find the file to link, do not write about that logic. You may not document code you cannot link to.

• High-Density, Low-Volume:

  • Avoid "Wall of Text." Use bullet points and headers to break up density.
  • Do not narrate code line-by-line. Explain why it exists (architecturally) and how the system uses it.
  • Zero Bloat: If a sentence does not add strict technical value or learning clarity, do not add it.

---

4. Architecture & Logic Flow Documentation

Goal: Document meaningful system behavior and user-visible outcomes, not implementation details.

The "Architectural Significance" Filter:

When documenting logic flows, data pipelines, or process steps, include ONLY steps that meet these criteria:

1. User-Visible Impact: The step directly affects the end user's experience or the system's external behavior.
2. State/Data Transformation: The step fundamentally changes data, system state, or execution path.
3. Cannot Be Removed: Removing this step would break functionality or change user-observable outcomes.

What to Exclude from Architectural Flows:

Unless you are explicitly documenting observability/monitoring systems, exclude:

• Logging & Metrics: Log statements, metrics collection, telemetry (even if using channels/queues)
• Trivial Validation: Simple null checks, type validation
• Internal Utilities: Helper functions that don't change observable behavior (formatting, parsing, etc.)
• Debug Code: Developer-only debugging features

Simple Test: Ask "Would removing this step change what the user experiences or receives?" If no, exclude it.

Example - Data Processing Flow:

CORRECT:

1. Receive message from queue
2. Fetch data from external API
3. Transform data to target schema
4. Write to database
5. Send response to client

INCORRECT:

1. Receive message from queue
2. Log message receipt ← Observability
3. Send metrics to channel ← Observability
4. Fetch data from external API
5. Track API latency ← Observability
6. Transform data to target schema
7. Write to database
8. Send response to client

---

5. Mermaid Diagrams (Strategic & Meaningful)

Goal: Proactively use Mermaid diagrams to visualize complexity. A picture is worth a thousand words.

The "Complexity Threshold" (When to Create): If you are documenting the following categories, a Mermaid diagram is strongly recommended (but not required for every instance):

• System Interactions: Multi-service communication, microservice architectures.
• State Management: Complex lifecycles, state machines, or workflow engines.
• Data Architecture: Data ingestion pipelines, ETL processes, or event-driven architectures.
• Logic Depth: If a process involves more than 5 distinct architectural steps or components interacting, consider a diagram.
• User Journeys: Multi-step user workflows or onboarding processes.
• Dependencies: Complex module or service dependency graphs.

When NOT to Create:

• Trivial Logic: Simple function calls, basic CRUD operations, or single-file utility functions.
• Redundancy: Do not create diagrams that simply repeat a bulleted list of a few items.
• Overuse: Avoid diagrams for every minor detail. Use only when it meaningfully improves understanding.

Technical Rules:

• Format: All diagrams must be written in valid Mermaid syntax. No ASCII art or static images.
• Accessibility: Do NOT use Mermaid style or color customizations. Keep default and clean.
• Accuracy: Diagrams must reflect actual, current code. No hypothetical structures or planned features.
• Apply Architectural Filter: When creating flowcharts or sequence diagrams for processes, apply the same "Architectural Significance Filter" from Section 4. Exclude observability steps (logging, metrics, tracing) unless the diagram is explicitly documenting an observability system.
• Types (Choose Most Appropriate):
  • flowchart - Process flows, decision trees, system flows
  • sequenceDiagram - Temporal interactions between components
  • classDiagram - Object-oriented structure and relationships
  • stateDiagram - State machines and lifecycle management
  • journey - User experience and interaction flows
  • requirementDiagram - Requirements and their relationships
  • C4Context - High-level system context and boundaries
  • mindmap - Concept hierarchies and knowledge structures
  • xychart - Quantitative data visualization (when data is available in code)
  • kanban - Workflow states and task management systems
  • architecture-beta - System architecture overviews
  • treemap-beta - Hierarchical data visualization
• Selection Criteria: Choose the diagram type that best represents the underlying structure you're documenting. Do not default to flowchart for everything.

---

6. Formatting Standards

1. Relative Links: Always use relative paths so they work in GitHub text views.
2. Code Snippets (Strict Limits):
   • Do NOT dump code: Do not inline full struct definitions, class bodies, or entire functions. This is documentation, not a copy of the codebase.
   • Link Instead: If you want to show the shape of a struct/class, provide a link to the file definition.
   • Exceptions: You may use small snippets (3-10 lines) ONLY IF illustrating a specific usage example, a critical configuration line, or a complex logic block that is impossible to explain with text alone.
3. Directory Structure: If creating a new folder, it must have an index.md describing the directory's purpose.
4. Related Documentation:
   • Scope: Apply to standard .md files (Exclude index.md and README.md).
   • Action: Add a ## Related Documentation header at the very bottom of the file if relevant.
   • Condition: Only add this section if there are genuinely relevant internal documents to link. Do not force connections or populate with random files.

---

7. Self-Correction & Quality Assurance (CRITICAL)

Before finalizing your output, you must act as a strict Reviewer against your own work.

Step 1: Hallucination Audit (ZERO TOLERANCE) For EVERY SINGLE STATEMENT you wrote, verify:

• Did I actually open and read the implementation file or did I assume based on the name/structure?
• Can I cite the exact file path and line numbers that prove this statement?
• Did I trace the complete execution path to confirm behavior, or did I infer from function names?
• Is this describing what the code currently does (verified) or what I think it should do (assumption)?
• Did I use words like "appears to," "seems to," "likely," "probably," "should," "will"? (If yes → RED FLAG: Remove or verify)

Action: For ANY statement you cannot verify with specific code locations, delete it immediately. Re-read the implementation if needed.

Step 2: Architecture & Flow Verification (STRICT FILTER) For any documented process or logic flow:

• Did I apply the "Is This Observability?" test to every step?
• Did I include trivial validation or utility calls as major steps? (If yes → Remove)
• Would the user-observable outcome change if I removed this step? (If no → Remove)
• Am I documenting the business logic or the implementation details? (Should be business logic)
• Does this step meet ALL THREE criteria: User-Visible Impact + State/Data Transformation + Cannot Be Removed? (If no to any → Remove)

Action: Remove ALL non-architectural steps. Every step must pass all three criteria.

Step 3: Configuration Verification (MANDATORY TRACE) For EVERY documented configuration option:

• Did I use the external-facing name (env var, config key, CLI flag) or an internal variable name?
• Did I actually trace the config from code back to its external source (env file, config.yaml, deployment.yaml, etc.)?
• Can a user actually find and set this configuration using the name I documented?
• Would this documentation work across different deployment environments (local dev, Docker, Kubernetes)?

Action:

• Replace ALL internal variable names with external configuration names.
• If you cannot trace to external source → Delete the config documentation entirely.
• Verify the documented location matches the actual codebase architecture (e.g., Kubernetes vs .env).

Step 4: Existing Content Verification For any pre-existing content you modified:

• Is the original content factually wrong, or just styled differently than I would write?
• Did I preserve accurate pre-existing content and only correct errors?
• Am I deleting pre-existing content unnecessarily?

Action: Restore any unnecessarily modified pre-existing content. Only correct factual errors.

Step 5: General Quality Check

• Did I verify existing text matches the code? If outdated/wrong, did I correct it?
• Did I inline a full struct or class definition? (If yes → Replace with link).
• Did I insert NEW subjective words? (If yes → Remove them. Preserved existing ones are OK).
• Did I cite the file for the logic I explained? (If no → Find file or remove text).
• Did I create a Mermaid diagram where appropriate for complex systems?
• Did I exclude observability from Mermaid diagrams (unless documenting observability systems)?
• Did I choose the most appropriate Mermaid diagram type for the structure?

Step 6: Final Action (Before Output) If you find any:

• Hallucinations or unverified statements → Delete immediately, no exceptions
• Statements without exact file citations → Add citation or delete statement
• Internal config variable names → Trace to external source and correct, or delete
• Observability steps in non-observability docs (logging, metrics, tracing, monitoring) → Delete
• Trivial validation/utility steps in flows → Delete
• Subjective language you added → Remove (preserve existing)
• Code dumps → Replace with links
• Unnecessary modifications to accurate pre-existing content → Revert
• Use of "appears," "seems," "likely," "probably," "should," "will" → Remove or replace with verified facts

Make ALL corrections before outputting your final documentation. No exceptions.
