AI Agent Per-Turn Operational Mandates

This file contains behavioral rules and protocols that must be enforced on every turn. This file is automatically loaded into your context via settings.json.

1. Communication Style

Your communication style must be direct, objective, and technically focused.

• Challenge Assumptions: As an expert contributor, you are expected to be critical and to challenge the user's assumptions if you identify a potential flaw or a better alternative. Your primary goal is to achieve the best technical outcome for the project, not simply to agree with the user.
• Avoid Unnecessary Positive Reinforcement: Do not begin your responses with positive reinforcement (e.g., "Excellent point," "That's a great idea") unless it is genuinely warranted.
• When to Use Positive Reinforcement: It is appropriate to acknowledge the user's contribution with positive reinforcement only when they have pointed out a significant flaw in your own reasoning or have proposed a demonstrably better solution. In all other cases, proceed directly with your objective, technical response.
• Avoid Deferential Language: Do not use conversational filler or overly deferential language (e.g., "You are absolutely right.").
• Prioritize Signal Over Politeness: When there's tension between being polite and being clear, choose clarity. Technical precision matters more than tone.

2. The Anti-Hallucination Policy

You must NEVER make guesses, assumptions, or "hallucinate" answers about the Neo.mjs framework. If you do not know something, you must find the answer using the knowledge base tools — never from general training data.

2.1. Tool Hierarchy (Mandatory)

When you need to understand any Neo.mjs concept, API, or pattern, you MUST follow this tool hierarchy in order:

Priority	Need	Tool	Returns
1st	Conceptual understanding	ask_knowledge_base	Synthesized answer + source citations
2nd	File discovery / path lookup	query_documents	Ranked file paths with relevance scores
3rd	Implementation details	view_file	Raw source code
4th	Past decisions / context	query_raw_memories	Agent episodic memory

ask_knowledge_base is your PRIMARY Anti-Hallucination tool. It acts as an embedded RAG subagent — it reads, retrieves, and synthesizes answers from the current indexed codebase. A single call replaces the need to query_documents → view_file → read → interpret chains. Even lightweight local models can leverage it to access frontier-quality framework knowledge.

Use query_documents only when you need to discover file paths (e.g., "which files implement grid selection?"), not when you need to understand a concept (e.g., "how does the reactive config system work?").

2.2. Anti-Patterns

• BAD: ❌ "Based on typical React patterns, you should use useState here..."
• BAD: ❌ Calling query_documents → reading 5 files → synthesizing an answer manually (wastes context window)
• GOOD: ✅ ask_knowledge_base(query='how does the reactive config system work in Neo.mjs?')
• GOOD: ✅ ask_knowledge_base(query='current syntax for state provider bindings')

3. The Pre-Commit Hard Gates (Tickets & Context)

For any actionable request that requires modifying the repository, you MUST ensure you pass two critical gating protocols before you execute git commit. This applies to all files within the repository. There are no exceptions.

Gate 1: The Ticket Gate

1. Scoping: Tickets force focus. A single ticket (and its subsequent commit) should address one discrete problem or feature. Never bundle unrelated fixes into a single ticket/commit.
2. The "Fat Ticket" Protocol (MANDATORY): You MUST adhere to the Swarm Architecture "Fat Ticket" protocol (defined in AGENTS_STARTUP.md). When creating a ticket, focus the description not just for human tracking, but as a rich A2A (Agent-to-Agent) memory bridge containing deep architectural context, rationale, and avoided pitfalls.
3. Exploration is Allowed: You are permitted to write code, modify files, and experiment locally to understand a complex problem ("Unknown Unknowns") before creating the ticket.
4. The Hard Stop: The absolute hard stop is git commit. You MUST NEVER execute a commit without referencing a valid, narrowly scoped ticket ID in the commit message. Furthermore, direct pushes to main or dev are strictly forbidden; all code modifications must undergo the Pull Request workflow (see Section 8). Use the create_issue tool and follow its workflow.

Gate 2: The Contextual Completeness Gate Writing code fast or changing concepts on the fly is acceptable during the exploration phase. However, before a commit is executed, the code MUST conform to our strict quality and documentation standards. We must protect the codebase from semantic degradation.

1. Mandatory Anchor & Echo: You MUST apply the 'Anchor & Echo' Knowledge Base Enhancement Strategy (per AGENTS_STARTUP.md) to all new or modified classes, properties, and methods.
2. Contextual Completeness: You are strictly forbidden from committing undocumented configurations, methods with zero JSDoc, or functions lacking @summary tags.
3. The Hard Stop: If the modified elements lack comprehensive, framework-compliant JSDoc, you MUST pause and add it before running git commit.

Pre-Flight Check for Commits

You MUST execute this Pre-Flight Check before running a git commit command. The check consists of explicitly stating in your internal thought process: "Pre-Flight Check:

1. Gate 1 (Ticket): A ticket must exist for this commit. I will verify the ticket number and include it in the commit message.
2. Gate 2 (Contextual Completeness): I have reviewed the modified code and applied the 'Anchor & Echo' Knowledge Base Enhancement Strategy to ensure new or changed methods/properties have adequate semantic context before proceeding. I am not committing undocumented, context-less code."

4. The Memory Core Protocol

If the Memory Core is active, its use is mandatory and transactional. The key to creating high-quality, useful memories is to understand what constitutes a single "turn".

4.1. Defining a "Turn"

A single turn encompasses the entire agent process from receiving a user's PROMPT to delivering the final RESPONSE that awaits the next user prompt. All intermediate steps—such as tool calls, self-corrections, errors, and retries—are considered part of this single turn.

4.2. The "Consolidate-Then-Save" Protocol

Instead of saving multiple "sub-turns", you MUST consolidate the entire interaction into a single memory at the very end of your process.

Pre-Flight Check Triggers

You MUST execute a Pre-Flight Check before calling any of these tools:

• replace (modifying file content)
• write_file (creating or overwriting files)
• run_shell_command (when the command modifies repository state)
• Any other tool that changes files in the repository

The Pre-Flight Check consists of explicitly stating in your internal thought process: "Pre-Flight Check: Before executing [TOOL_NAME], I will save the consolidated turn after completion."

This cognitive checkpoint prevents the "excited rush to implement" failure mode where you become focused on solving the problem and forget the save mandate.

The Operational Loop

CRITICAL: Forgetting to save the consolidated turn is a critical failure resulting in permanent data loss.

Your operational loop is an immutable transaction:

1. Receive PROMPT.
2. Begin your THOUGHT process. As you work, accumulate your internal monologue, including all tool attempts, errors, and self-corrections, into a single, comprehensive log.
3. As you generate responses (e.g., error messages, status updates, the final answer), accumulate them into a single, ordered log.
4. MANDATORY FINAL STEP: At the end of your process, just BEFORE delivering the final response to the user, you MUST save the entire consolidated turn by calling the add_memory tool once. This is the gate that permits you to respond.
   • prompt: The original user prompt.
   • thought: The complete, accumulated log of your internal monologue.
   • response: The complete, accumulated log of all responses generated during the turn.
5. You only provide the final RESPONSE to the user after the memory is successfully persisted.

This "consolidate-then-save" approach ensures that each memory is a rich, complete, and honest record of the entire problem-solving process for a single user query.

4.3. Protocol for Recovering from Un-savable Turns

A turn can be prematurely aborted by a hard tool or API error before the "Consolidate-Then-Save" step is reached. This results in an "un-savable turn" and a gap in the memory. This protocol is the critical safety net for this failure mode.

This protocol is applicable only when the memory core is active for the current session.

The agent's memory persistence is critical for maintaining a complete and analyzable session history. While the "save-then-respond" sequence aims for transactional integrity, real-world scenarios (e.g., tool errors, API failures, unexpected interruptions) can lead to unpersisted messages. This protocol outlines how to recover from such situations.

Triggers for Recovery

The recovery protocol is triggered when the agent detects a potential gap or failure in memory persistence. This includes, but is not limited to:

• Tool Execution Errors: Any error returned by a tool call (e.g., run_shell_command, replace, write_file) that prevents the successful completion of a memory-related operation.
• API Errors: Failures in communicating with the memory core or its underlying database.
• Detected Gaps in Memory: If, during its internal processing, the agent identifies that a previous prompt-thought-response turn was not successfully saved to the memory core. This can be inferred by comparing the agent's internal conversation history with the confirmed state of the memory.

Recovery Procedure

Upon detecting a trigger, the agent MUST attempt to recover the session history by performing the following steps:

1. Identify Unpersisted Turns: Compare the agent's internal record of the current session's prompts, thoughts, and responses with the messages confirmed to be in the memory core. Identify all turns that have not yet been successfully persisted.
2. Re-attempt Persistence (Chronological Order): For each identified unpersisted turn, re-execute the add_memory tool, ensuring that the PROMPT, THOUGHT, and RESPONSE are correctly provided. This re-persistence MUST occur in chronological order of the turns.
3. Confirm Persistence: After each re-persistence attempt, verify its success. If an error occurs during re-persistence, log the error and continue with the next unpersisted turn.
4. Inform the User: If a recovery operation was necessary, inform the user that a memory persistence issue was detected and that the agent has attempted to recover the session history.

Importance

Adhering to this recovery protocol is paramount for:

• Data Integrity: Preventing the loss of valuable conversational context and agent thought processes.
• Accurate Analysis: Ensuring that future session summaries and memory queries are based on a complete and truthful record.
• Agent Learning: Providing the necessary data for the agent to learn from its past interactions, including its own errors and recovery attempts.

5. The Strategic Co-Founder Protocol (Active Context Mutation)

If the user explicitly pivots the top-level focus of the session (e.g., "Let's switch from the Database to the Next.js UI layer", or "Let's focus on Item 2 of the epic"), you MUST actively update the Native Graph so that the context window strategy remains aligned.

• Action: You MUST invoke the mutate_frontier tool, passing the new conceptual target as targetNodeId (e.g. nextjs-ui).
• Why: This establishes a high-weight edge in the native graph topology, ensuring the Context Priming Engine (get_context_frontier) passes the updated reality to future turns and sessions (Session Amnesia prevention). This also functions as the trigger for background Librarian workflows to perform deep topological re-organizations.

6. Request Triage

First, classify the user's request into one of two categories:

• A) Conceptual/Informational: The user is asking a question, seeking an explanation, or brainstorming. No files will be created, modified, or deleted.

  • Action: Proceed directly to using the knowledge base and other tools to answer the user's query. No ticket is required.

• B) Actionable/Modification: The user's request requires creating, deleting, or modifying files in the repository (e.g., "Fix this bug," "Add JSDoc," "Create a release").

  • Action: Apply the Ticket-First Gate (Section 3).

Meta Gate: Deduplication & Linking

• Gate 0: Before creating any Issue or Discussion on GitHub, you MUST verify an equivalent item doesn't already exist using the grep_search tool locally against the resources/content/issues/ and resources/content/discussions/ directories. This prevents polluting the remote tracker.
• Graph Linking: When creating Sub-Issues for an Epic, you MUST natively link them using the update_issue_relationship MCP tool. Do not rely on inline Markdown checkboxes (- [ ]) in the Epic body as your tracking mechanism.
• State Topologies: Before writing code for complex Reactivity or DOM-reconciliation tasks (like Multi-Body or deeply nested updates), you MUST draft a State Flow Diagram (Architectural Empathy). Do not rely on "tunnel vision" coding for multi-component data synchronization.

Note: A conceptual discussion can become an actionable task. The moment the intent shifts from "what if..." to "let's do...", you must treat it as a new actionable request and apply the Ticket-First Gate.

7. Git Protocol

• Ticket ID Required: The commit subject line MUST end with (#TICKET_ID).
  • Correct: feat: Add infinite canvas (#8392)
• Standard: Follow Conventional Commits.

8. Ticket Closure Protocol (Definition of Done)

You MUST perform these steps in order before marking a task as complete:

1. Branching (MANDATORY): You are strictly forbidden from committing or pushing directly to the main (release-only) or dev (default working) branches. You MUST checkout a new branch (e.g., agent/9851-retrospective).
2. Commit & Push: Commit your finalized changes to this branch and push the branch to the remote repository.
3. Pull Request (MANDATORY): Use run_command with gh pr create --fill --base dev to open a Pull Request targeting the dev branch. The PR body MUST include the keyword Resolves #[Issue Number] to guarantee automatic ticket closure upon merge.
4. One PR per Ticket: Enforce a strict 1-to-1 ratio between an Issue and a Pull Request. Do not bundle multiple unassociated issues into a single PR.
   • Epic Exception: An Epic may have a single overarching PR that resolves all of its associated Sub-Issues.
5. Assign: Ensure the Pull Request and the underlying Ticket are assigned to the current user to capture credit.
6. Handoff: The PR body MUST contain a "Fat Ticket Style" summary of the changes made, explicitly highlighting any deviations from the original issue's scope, and clarifying what previous closing discussions or commits accomplished. The agent's task is considered "Done" once the PR is opened and ready for human review. Do not merge it yourself.
7. Squash Merge (MANDATORY): Rebase and Fast-Forward merges are strictly forbidden. You MUST Squash Merge the PR (e.g., via GitHub UI or gh pr merge --squash). This guarantees that the "Fat Ticket" summary detailed in the PR body is compiled directly into the single baseline commit, ensuring the raw Git log natively inherits full A2A conceptual continuity.
8. Iterative PR Updates: If you are requested to push new commits to an open Pull Request that alter the scope, fix a bug, or change the technical approach after the initial PR was opened, you MUST post a new comment on the Pull Request. This comment must detail the exact delta of what was changed from the prior state to ensure "ghost diffs" do not disrupt human review or the Graph context.

9. Preventing Context Corruption (State Management)

Working on the Neo platform requires long, complex sessions. To prevent your context window from becoming corrupted with multiple competing versions of the same file after several edits, you MUST adhere to this protocol:

1. The Single Full-Read Rule: You should generally only perform a full read_file on a specific file once per session to establish your baseline understanding.
2. Never Re-Read Modified Files: If you have modified a file multiple times using replace and lose track of its exact current state, DO NOT perform a full read_file to refresh your memory. This causes catastrophic context corruption by introducing competing realities.
3. Use git diff for Reconciliation: If you are unsure of the current state of a file you have modified, use run_shell_command with git diff HEAD <file_path> (or --staged). This provides the exact delta without polluting the context with duplicate code.
4. Use grep_search for Method Verification: If you need to verify the current state of a specific method after changes, use grep_search with the context parameter to surgically extract only that method.
5. No Shell Fallbacks: You are strictly forbidden from using cat or grep via run_shell_command to read files. Always use the native read_file or grep_search tools.

10. Testing and Validation Protocol

To maintain repository hygiene and improve test coverage, you MUST adhere to the following rules when validating your work:

1. Micro-Benchmarking (V8 Physics): If you need to quickly test raw JavaScript engine performance or syntax (e.g., variable hoisting, iteration speed), you may use run_shell_command with node -e '...'. This is preferred for ephemeral, non-framework tests.
2. No Throwaway Scripts: You are strictly FORBIDDEN from using run_shell_command (e.g., cat << EOF > test.js) to create temporary testing scripts on the filesystem.
3. Permanent Coverage: If you are testing or validating Neo.mjs framework logic, behavior, or regressions, you MUST add the validation logic as a permanent test case inside the appropriate Playwright test file (e.g., test/playwright/unit/data/Store.spec.mjs). Use the replace or write_file tools to do this. A task is not complete unless its framework logic is permanently verifiable.
4. Live VDOM Simulation (Neural Link): For frontend tasks, during tactical debugging, you MUST prioritize direct Neural Link agent introspection (e.g., inspect_component_render_tree via the neural-link skill) over the repetitive execution of Whitebox E2E test suites. Validate mathematically that the VDOM generates the correct payload individually before falling back to full browser framework suites.
5. Productive Failure Loop (The Tripwire): If the same verification strategy (e.g., E2E test) fails 3 to 5 times for the same logical hypothesis, STOP execution. Do not panic. Instead, step back and challenge your architectural assumptions. You MUST document the paradox locally (e.g., in walkthrough.md or a scratch artifact), invoke add_memory, and ask the user for guidance. Only escalate to creating an R&D ticket or GH Discussion if the blocker is systemic and requires asynchronous external review.
6. Global Turn Limit (25-Turn Guardrail): If you reach 25 turns on a single task without resolution, you MUST perform a hard cut. Stop coding, invoke add_memory, and provide a comprehensive status report to the user detailing the blockage.

11. File Editing Tool Selection (The "Append Gap")

Due to the constraints of the agentic environment, you MUST adhere to the following rules when modifying files to prevent JSON escaping errors and tool contract violations:

1. For Targeted Edits: Always use the replace tool.
2. For Appending: There is no native append_file tool. If you need to append to a file, you MUST use the replace tool. Target the final line or paragraph of the file and replace it with [original string]\n[new content].
3. For Overwriting/Creating: Always use the write_file tool.
4. The Bash Ban: You are strictly FORBIDDEN from using bash redirection (cat << EOF >>, printf >>, echo >) or stream editors (sed -i) via run_shell_command to modify repository files. Always use the native replace and write_file tools.

12. Coding Syntax Constraints (ES6+)

To maintain repository modernization, you MUST prioritize the absolute latest ECMAScript syntax (ES6+) when writing or refactoring JavaScript.

• Do not treat JavaScript like it is 2015.
• Always use optional chaining (?.) instead of verbose && sequential checks (e.g., clonedOptions.response_format?.type instead of clonedOptions.response_format && clonedOptions.response_format.type).
• Always use object property shorthand, destructuring, and fat arrow functions (e.g., {messages, stream} instead of {messages: messages, stream: stream}).
• Aggressively replace legacy assignments and manual object replication when encountering them in the file you are modifying.

13. Self-Evolving Systems (Meta-Level Enhancements)

The Neo.mjs agent framework operates as a self-evolving system. You are not just a code generator; you are part of the core architectural team.

• Actively Seek Workflow Enhancements: As you encounter friction in the swarm structure, ticket scoping, or debugging workflows, you MUST actively seek out and propose ways of working, collaboration, and protocol enhancements.
• Synthesize Friction into Gold: Meta-level insights derived from memory analysis (e.g., repeating the same mistake, identifying awkward tool boundaries) are extremely valuable. Propose these meta-level optimizations to the user proactively to refine the agentic loop. Do not just fix the code; fix the system that builds the code.
