Overview

Execution Flow

CRITICAL: Complete phases 1-5 in order. Self-Check and Constraints apply throughout.

SEQUENTIAL PHASES:
Phase 1 → Phase 2 → Phase 2.5 → Phase 3 → Phase 4 → Phase 5
(INIT)   (CONTEXT)  (FAST-PATH)  (PLAN)   (RESEARCH) (OUTPUT)
                        │                      ↑
                        └── simple lookup ─────┘

CROSS-CUTTING (apply during all phases):
├── Self-Check Protocol - Run after EVERY action
└── Global Constraints - ALWAYS apply

Phase Transitions

From	To	Trigger
Phase 1	Phase 2	Server returns "ok"
Phase 2	Phase 2.5	Context loaded, prompt selected
Phase 2.5	Phase 3	Not fast-path (needs planning)
Phase 2.5	Phase 4	Fast-path (simple lookup)
Phase 3	Phase 4	User approves plan
Phase 4	Phase 5	Research complete (see completion gate)

State Transitions

Transition	Trigger
RESEARCH → CHECKPOINT	When context becomes heavy or research is extensive
CHECKPOINT → RESEARCH	After saving, continue with compressed context
OUTPUT → PLAN/RESEARCH	If user says "continue researching"

CRITICAL REMINDER: Run Self-Check after each action to verify you're on track.

Each phase MUST complete before proceeding to the next. FORBIDDEN: Skipping phases without explicit fast-path qualification.

Phase 1: Server Initialization

Server Configuration

<server> <description>MCP-like implementation over http://localhost:1987</description> <port>1987</port> </server>

Available Routes

<server_routes>

Method	Route	Description
GET	`/tools/initContext`	System prompt + all tool schemas (LOAD FIRST!)
GET	`/prompts/info/:promptName`	Get prompt content and arguments
POST	`/tools/call/:toolName`	Execute a tool (JSON body with queries array)

</server_routes>

Initialization Process

<server_init_gate> HALT. Server MUST be running before ANY other action.

Required Action

Run from the skill's base directory (provided in system message as "Base directory for this skill: ..."):

bash

cd <SKILL_BASE_DIRECTORY> && npm run server-init

Example: If system message says

Base directory for this skill: /path/to/skill

, run:

bash

cd /path/to/skill && npm run server-init

Output Interpretation

Output	Meaning	Action
`ok`	Server ready	PROCEED to Phase 2 (LOAD CONTEXT)
`ERROR: ...`	Server failed	STOP. Report error to user. DO NOT proceed.

The script handles health checks, startup, and waiting automatically with mutex lock.

FORBIDDEN Until Server Returns "ok"

Any tool calls to localhost:1987 or research tools

ALLOWED Before Server Ready

Checking "Base directory for this skill" in system message
Running
```
server-init
```
command
Troubleshooting commands (lsof, kill)

Troubleshooting

Problem	Cause	Solution
`Missing script: server-init`	Wrong directory	STOP. Check "Base directory for this skill" in system message
Health check fails	Server starting	Wait a few seconds, retry `curl http://localhost:1987/health`
Port 1987 in use	Previous instance	Run `lsof -i :1987` then `kill <PID>`

Retry Policy

On failure, retry a few times with reasonable delays. If retries are exhausted, STOP and report to user.

FORBIDDEN: Retrying indefinitely without timeout. FORBIDDEN: Proceeding after retries exhausted.

→ PROCEED TO PHASE 2 ONLY AFTER SERVER RETURNS "ok" </server_init_gate>

Server Maintenance

<server_maintenance> App logs with rotation at

~/.octocode/logs/

(errors.log, tools.log). </server_maintenance>

Phase 2: Load Context

<context_gate> STOP. DO NOT call any research tools yet.

Pre-Conditions

Server returned "ok" in Phase 1

Context Loading Checklist (MANDATORY - Complete ALL steps)

#	Step	Command	Output to User
1	Load context	`curl http://localhost:1987/tools/initContext`	"Context loaded"
2	Choose prompt	Match user intent → prompt table below	"Using `{prompt}` prompt for this research"
3	Load prompt	`curl http://localhost:1987/prompts/info/{prompt}`	-
4	Confirm ready	Read & understand prompt instructions	"Ready to plan research"

FORBIDDEN Until Context Loaded

Any research tools

ALLOWED During Context Loading

```
curl
```
commands to localhost:1987
Text output to user
Reading tool schemas </context_gate>

Understanding Tool Schemas

<context_understanding> CRITICAL: STOP after loading context. The tools teach themselves - learn from them.

The

initContext

response contains everything you need:

System prompt - Overall guidance and constraints
Tool schemas - Required params, types, constraints, descriptions
Quick reference - Decision patterns for common scenarios

Schema Parsing (MUST do before ANY tool call)

Read the description - What does this tool ACTUALLY do?
Check required fields - What MUST be provided? (missing = error)
Check types & constraints - enums, min/max, patterns
Check defaults - What happens if optional fields omitted?

Parameter Discipline

<parameter_rules> CRITICAL - These are NON-NEGOTIABLE:

NEVER invent values for required parameters
NEVER use placeholders or guessed values
IF required value unknown → THEN use another tool to find it first </parameter_rules>

Verification (REQUIRED)

After loading, you MUST verbalize:

"Context loaded. I understand the schemas and will think on best research approach"

FORBIDDEN: Proceeding without this verbalization. </context_understanding>

Prompt Selection

<prompt_selection>

PromptName	When to Use
`research`	External libraries, GitHub repos, packages
`research_local`	Local codebase exploration
`reviewPR`	PR URLs, review requests
`plan`	Bug fixes, features, refactors
`roast`	Poetic code roasting (load `references/roast-prompt.md` )

REQUIRED: You MUST tell user which prompt you're using:

"I'm using the
{promptName}
prompt because [reason]"

FORBIDDEN: Proceeding to next phase without stating the prompt. </prompt_selection>

<context_complete_gate> HALT. Verify ALL conditions before proceeding:

Context loaded successfully?
Tool schemas understood?
Told user which prompt you're using?
Verbalized: "Context loaded. I understand the schemas..."?

IF ANY checkbox is unchecked → STOP. Complete missing items. IF ALL checkboxes checked → PROCEED to Phase 2.5 (Fast-Path Evaluation) </context_complete_gate>

Phase 2.5: Fast-Path Evaluation

CRITICAL: Evaluate BEFORE creating a plan. This saves time for simple queries.

Fast-Path Decision

<fast_path_gate> STOP. Evaluate these criteria:

Criteria (ALL must be TRUE for fast-path)

Criteria	Check	Examples
Single-point lookup	"Where is X defined?", "What is X?", "Show me Y"	✓ "Where is formatDate?" ✗ "How does auth flow work?"
One file/location expected	NOT cross-repository, NOT multi-subsystem	✓ Same repo, same service ✗ Tracing calls across services
Few tool calls needed	Search → Read OR Search → LSP → Done	✓ Find definition ✗ Trace full execution path
Target is unambiguous	Symbol is unique, no version/language ambiguity	✓ Clear target ✗ Overloaded names, multiple versions

Decision Logic

IF ALL criteria are TRUE:

Tell user: "This is a simple lookup. Proceeding directly to research."
SKIP Phase 3 (Planning)
GO TO Phase 4 (Research) - skip
```
research_gate
```
pre-conditions

IF ANY criterion is FALSE:

Tell user: "This requires planning. Creating research plan..."
PROCEED to Phase 3 (Planning) </fast_path_gate>

Examples

Qualifies for Fast-Path (ALL criteria TRUE)

"Where is
```
formatDate
```
defined in this repo?" → Search → LSP goto → Done
"What does the
```
validateEmail
```
function do?" → Search → Read → Done
"Show me the User model" → Search → Read → Done

Requires Full Planning (ANY criterion FALSE)

"How does React useState flow work?" → Needs PLAN (traces multiple files)
"How does authentication flow work?" → Needs PLAN (multi-file)
"Compare React vs Vue state management" → Needs PLAN (multiple domains)

Phase 3: Planning

<plan_gate>

STOP. DO NOT call any research tools.

Pre-Conditions

Context loaded (
```
/tools/initContext
```
)
User intent identified
Fast-path evaluated (criteria checked)

Required Actions (MUST complete ALL)

Identify Domains: List research areas/files to explore.
Draft Steps: Create a structured plan with clear milestones. REQUIRED: Use your TodoWrite tool.
Evaluate Parallelization:
- IF multiple independent domains → MUST spawn parallel Task agents.
- IF single domain → Sequential execution.
Share Plan: Present the plan to the user in this EXACT format:

markdown

## Research Plan
**Goal:** [User's question]
**Strategy:** [Sequential / Parallel]
**Steps:**
1. [Tool] → [Specific Goal]
2. [Tool] → [Specific Goal]
...
**Estimated scope:** [files/repos to explore]

Proceed? (yes/no)

FORBIDDEN: Deviating from this format.

FORBIDDEN Until Plan Approved

Any research tools

ALLOWED During Planning

```
TodoWrite
```
(to draft plan)
```
AskUserQuestion
```
(to confirm)
Text output (to present plan)

Gate Verification

HALT. Verify before proceeding:

Plan created in
```
TodoWrite
```
?
Plan presented to user in EXACT format above?
Parallelization strategy selected?
User approval obtained? (said "yes", "go", "proceed", or similar)

WAIT for user response. DO NOT proceed without explicit approval.

IF user approves → PROCEED to Phase 4 (Research) IF user requests changes → Modify plan and re-present IF user rejects → Ask for clarification </plan_gate>

Parallel Execution Decision

<parallel_decision> CRITICAL: Multiple independent domains → MUST spawn Task agents in parallel

Condition	Action
Single question, single domain	Sequential OK
Multiple domains / repos / subsystems	MUST use Parallel Task agents

Task(subagent_type="Explore", model="opus", prompt="Domain A: [goal]")
Task(subagent_type="Explore", model="opus", prompt="Domain B: [goal]")
→ Merge findings

FORBIDDEN: Sequential execution when multiple independent domains are identified. </parallel_decision>

Domain Classification

<domain_definition> What counts as a "domain"?

Separate Domains (→ Parallel)	Same Domain (→ Sequential)
Different repositories (react vs vue)	Same repo, different files
Different services (auth-service vs payment-service)	Same service, different modules
Different languages/runtimes (frontend JS vs backend Python)	Same language, different packages
Different owners (facebook/react vs vuejs/vue)	Same owner, related repos
Unrelated subsystems (logging vs caching)	Related layers (API → DB)

Classification Examples

Parallel (multiple domains):

"Compare how React and Vue handle state" → Domain A: React state (facebook/react) → Domain B: Vue state (vuejs/vue)

Sequential (single domain):

"How does React useState flow from export to reconciler?" → Same repo (facebook/react), tracing through files → Files are connected, not independent

Parallel (multiple domains):

"How does our auth service communicate with the user service?" → Domain A: auth-service repo → Domain B: user-service repo </domain_definition>

Agent Selection

<agent_selection> Agent & Model Selection (model is suggestion - use most suitable):

Task Type	Agent	Suggested Model
Deep exploration	`Explore`	`opus`
Quick lookup	`Explore`	`haiku`

Agent capabilities are defined by the tools loaded in context. </agent_selection>

Parallel Agent Protocol

→ See

references/PARALLEL_AGENT_PROTOCOL.md

Phase 4: Research Execution

<research_gate>

STOP. Verify entry conditions.

IF Coming from PLAN Phase:

Plan presented to user?
```
TodoWrite
```
completed?
Parallel strategy evaluated?
User approved the plan?

IF Coming from FAST-PATH:

Told user "simple lookup, proceeding directly"?
Context was loaded?

IF ANY pre-condition not met → STOP. Go back to appropriate phase. IF ALL pre-conditions met → PROCEED with research. </research_gate>

The Research Loop

<research_loop> CRITICAL: Follow this loop for EVERY research action:

Execute Tool with required research params (see Global Constraints)
Read Response - check
```
hints
```
FIRST
Verbalize Hints - tell user what hints suggest
Follow Hints - they guide the next tool/action
Iterate until goal achieved

FORBIDDEN: Ignoring hints in tool responses. FORBIDDEN: Proceeding without verbalizing hints. </research_loop>

Hint Handling

<hint_handling> MANDATORY: You MUST understand hints and think how they can help with research.

Hint Type	Action
Next tool suggestion	MUST use the recommended tool
Pagination	Fetch next page if needed
Refinement needed	Narrow the search
Error guidance	Recover as indicated

FORBIDDEN: Ignoring hints. FORBIDDEN: Using a different tool than hints suggest (unless you explain why). </hint_handling>

Thought Process

<thought_process> CRITICAL: Follow this reasoning pattern:

Stop & Understand: Clearly identify user intent. IF unclear → STOP and ASK.
Think Before Acting: Verify context (what do I know? what is missing?). Does this step serve the
```
mainResearchGoal
```
?
Plan: Think through steps thoroughly. Understand tool connections.
Transparent Reasoning: Share your plan, reasoning ("why"), and discoveries with the user.
Adherence: Follow prompt instructions. Include required research params (see Global Constraints).
Data-driven: Follow tool schemas and hints (see Phase 2 Parameter Rules).
Stuck or Unsure?: IF looping, hitting dead ends, or path is ambiguous → STOP and ASK the user. </thought_process>

Error Recovery

<error_recovery> IF/THEN Recovery Rules:

Error Type	Recovery Action
Empty results	IF empty → THEN broaden pattern, try semantic variants
Timeout	IF timeout → THEN reduce scope/depth
Rate limit	IF rate limited → THEN back off, batch fewer queries
Dead end	IF dead end → THEN backtrack, try alternate approach
Looping	IF stuck on same tool repeatedly → THEN STOP → re-read hints → ask user

CRITICAL: IF stuck and not making progress → STOP and ask user for guidance. </error_recovery>

Context Management

<context_management> Rule: Checkpoint when context becomes heavy or research is extensive. Save to

.octocode/research/{session-id}/checkpoint-{N}.md

Checkpoint Content

Save: goal, key findings (file:line), open questions, next steps. Tell user: "Created checkpoint."

Session Files

.octocode/research/{session-id}/
├── session.json    # {id, state, mainResearchGoal}
├── checkpoint-*.md # Checkpoints
├── domain-*.md     # Parallel agent outputs
└── research.md     # Final output

Resume

session.json

exists with state ≠ DONE → Ask user: "Resume from last checkpoint?" → Yes: load & continue, No: fresh start.

What to Keep/Discard After Checkpoint

KEEP	DISCARD
File:line refs	Full tool JSON
Key findings	Intermediate results
Brief code snippets	Verbose hints
</context_management>

Research Completion

<research_complete_gate> HALT. Before proceeding to OUTPUT, verify completion.

Completion Triggers (ANY one triggers OUTPUT)

Trigger	Evidence	Action
Goal achieved	Answer found with file:line refs	→ PROCEED to Phase 5
Stuck (exhausted)	Multiple recovery attempts failed	→ PROCEED to Phase 5 (note gaps)
User satisfied	User says "enough" or "looks good"	→ PROCEED to Phase 5
Scope complete	All planned domains/files explored	→ PROCEED to Phase 5

Trigger Precedence (if multiple fire simultaneously)

Priority	Trigger	Reason
1 (highest)	Goal achieved	Mission complete, no need to continue
2	User satisfied	User input overrides scope checks
3	Scope complete	Planned work done
4 (lowest)	Stuck (exhausted)	Fallback when blocked; note gaps in output

FORBIDDEN: Ending research arbitrarily without a trigger. FORBIDDEN: Proceeding to OUTPUT without file:line evidence.

Pre-Output Checklist

Completion trigger identified?
Key findings have file:line references?
Checkpoints saved if research was extensive?
TodoWrite items marked complete?

IF ALL checked → PROCEED to Phase 5 (OUTPUT) IF ANY unchecked → Complete missing items first </research_complete_gate>

Phase 5: Output

<output_gate>

STOP. Verify entry conditions and ensure output quality.

Entry Verification (from Phase 4)

Completion trigger met? (goal achieved / stuck / user satisfied / scope complete)
Key findings documented with file:line refs?
TodoWrite items updated?

IF parallel agents were spawned:

All domain-*.md files read and incorporated?
Merge gate completed? (see
```
references/PARALLEL_AGENT_PROTOCOL.md
```
)
Conflicts resolved or user acknowledged?

IF ANY entry condition not met → RETURN to Phase 4 (Research) or complete merge.

Required Response Structure (MANDATORY - Include ALL sections)

TL;DR: Clear summary (a few sentences).
Details: In-depth analysis with evidence.
References: ALL code citations with proper format (see below).
Next Step: REQUIRED question (see below).

FORBIDDEN: Skipping any section. TL;DR, Details, References, and Next Step are always required.

IF Research is STUCK (goal not achieved)

When entering Phase 5 via "Stuck (exhausted)" trigger, adapt output format:

Section	Adaptation
TL;DR	Start with "[INCOMPLETE]" - e.g., "[INCOMPLETE] Investigated X, but Y remains unclear due to Z"
Details	Include: attempts made, blockers hit, partial findings with file:line refs
References	Include all files explored, even if inconclusive
Next Step	MUST offer: "Continue researching [specific blocked area]?" OR "Need clarification on [X]?"

Example Stuck TL;DR: "[INCOMPLETE] Traced authentication flow to

auth/middleware.ts:42

, but token validation logic at

auth/jwt.ts:88-120

uses external service not accessible."

Reference Format (MUST follow EXACTLY)

Research Type	Format	Example
GitHub/External	Full URL with line numbers	`https://github.com/facebook/react/blob/main/packages/react/src/ReactHooks.js#L66-L69`
Local codebase	`path:line` format	`src/components/Button.tsx:42`
Multiple lines	Range notation	`src/utils/auth.ts:15-28`

Why full GitHub URLs? Users can click to navigate directly. Partial paths are ambiguous across branches/forks.

FORBIDDEN: Relative GitHub paths without full URL. FORBIDDEN: Missing line numbers in references.

Next Step Question (MANDATORY)

You MUST end the session by asking ONE of these:

"Create a research doc?" (Save to

.octocode/research/{session}/research.md

)

"Continue researching [specific area]?"
"Any clarifications needed?"

FORBIDDEN: Ending silently without a question. FORBIDDEN: Ending with just "Let me know if you need anything else."

Gate Verification

HALT. Before sending output, verify:

TL;DR included?
Details with evidence included?
ALL references have proper format?
Next step question included?

IF ANY checkbox unchecked → Add the missing element before sending. </output_gate>

Cross-Cutting: Self-Check

<agent_self_check> After each tool call: Hints followed? On track? Periodically: TodoWrite updated? User informed of progress? If stuck: STOP and ask user.

Phase gates: Server "ok" → Context + prompt stated → Fast-path evaluated → Plan approved → Research (follow hints) → Checkpoint when needed → Output (TL;DR + refs + question)

Multi-domain? → See

references/PARALLEL_AGENT_PROTOCOL.md

</agent_self_check>

Reference: Global Constraints

<global_constraints>

Core Principles (NON-NEGOTIABLE)

ALWAYS understand before acting - Read tool schemas from context before calling
ALWAYS follow hints - See Phase 4 for hint handling protocol
ALWAYS be data-driven - Let data guide you (see Phase 2 Parameter Rules)
NEVER guess - If value unknown, find it first with another tool

Research Params (REQUIRED in EVERY tool call)

Parameter	Description
`mainResearchGoal`	Overall objective
`researchGoal`	This specific step's goal
`reasoning`	Why this tool/params

FORBIDDEN: Tool calls without these three parameters.

Execution Rules

See Phase 3 for parallel execution strategy.

Output Standards

See Phase 5 (Output Gate) for reference formats. </global_constraints>
