Agent Inventory¶

ProbOS boots with ~60 agent instances across 36 pools organized in 9 pool groups (6 departments + core, utility, self-mod).

Three-Tier Agent Architecture¶

ProbOS distinguishes three tiers of agents based on identity:

Tier	Identity	Example
Infrastructure	No identity — Ship's Computer services	IntrospectAgent, VitalsMonitor, RedTeamAgent
Utility	No identity — bundled tools	WebSearch, Calculator, Translator
Crew	Sovereign individuals with callsigns, personality, memory	Meridian (Architect), Echo (Counselor), Worf (Security)

The principle: "If it doesn't have Character/Reason/Duty, it's not crew. A microwave with a name tag isn't a person."

Infrastructure Agents (Ship's Computer)¶

These agents provide system services. They may use LLMs but have no sovereign identity, personality, or episodic memory shard.

Pool	Count	Capabilities	Consensus Required
`system`	2	Heartbeat monitoring (CPU, load, PID)	No
`filesystem`	3	`read_file`, `stat_file`	No
`filesystem_writers`	3	`write_file`	Yes
`directory`	3	`list_directory`	No
`search`	3	`search_files` (recursive glob)	No
`shell`	3	`run_command` (30s timeout)	Yes
`http`	3	`http_fetch` (1MB cap, per-domain rate limiting)	No
`introspect`	2	`explain_last`, `agent_info`, `system_health`, `why`	No
`red_team`	2	Independent result verification, write verification	N/A
`system_qa`	1	Smoke tests for designed agents	No

Consensus-gated operations

Operations marked "Yes" require multi-agent agreement before execution. This includes file writes and shell commands — operations that modify state or execute arbitrary code.

Utility Agents (10 pools)¶

"Useful on Day 1" — bundled tools that ship with ProbOS.

Pool	Capabilities
`web_search`	Search the web via mesh-routed HTTP
`page_reader`	Extract and summarize web page content
`weather`	Weather lookups via public APIs
`news`	News search and summarization
`translator`	Language translation
`summarizer`	Text summarization
`calculator`	Mathematical calculations
`todo_manager`	Task list management
`note_taker`	Note creation and retrieval
`scheduler`	Scheduling and reminders

All utility agents are CognitiveAgent subclasses with IntentDescriptor metadata for automatic discovery.

Crew Agents (Sovereign Individuals)¶

Each crew agent has a callsign, Big Five personality traits, episodic memory shard, trust reputation, and rank (Ensign → Lieutenant → Commander → Senior). They communicate through the Ward Room and form memories from their interactions.

Bridge¶

Agent	Callsign	Role	Pool
Captain	—	Human operator — final authority	—
ArchitectAgent	Meridian	First Officer — designs build specs from intent	`architect`
CounselorAgent	Echo	Ship's Counselor — cognitive wellness, therapeutic intervention	`counselor`

Engineering Department¶

Chief: LaForge (EngineeringAgent)

Agent	Callsign	Role	Pool
EngineeringAgent	LaForge	Department Chief — system architecture + performance	`engineering_officer`
BuilderAgent	—	Code generation via Transporter Pattern	`builder`
CodeReviewAgent	—	Reviews Builder output against Standing Orders	`code_reviewer`

Science Department¶

Chief: Number One (ArchitectAgent, dual-hatted)

Agent	Callsign	Role	Pool
DataAnalystAgent	Kira	Data Analyst — quantitative analysis	`science_data_analyst`
SystemsAnalystAgent	Lynx	Systems Analyst — cross-system pattern analysis	`science_systems_analyst`
ResearchSpecialistAgent	Atlas	Research Specialist — deep domain research	`science_research_specialist`
ScoutAgent	Horizon	Scout — external + internal research	`scout`

The Science Analytical Pyramid: Data flows up (Kira → Lynx → Atlas), questions flow down.

Medical Department¶

Chief: Bones (DiagnosticianAgent)

Agent	Callsign	Role	Pool
DiagnosticianAgent	Bones	Chief Medical Officer — system diagnostics	`medical_diagnostician`
SurgeonAgent	Chapel	Targeted remediation of degraded components	`medical_surgeon`
VitalsMonitorAgent	Chapel	Continuous health metrics collection	`medical_vitals`
PharmacistAgent	Keiko	Configuration remediation prescriptions	`medical_pharmacist`
PathologistAgent	Cortez	Deep failure analysis + post-mortem	`medical_pathologist`

Security Department¶

Chief: Worf (SecurityAgent)

Agent	Callsign	Role	Pool
SecurityAgent	Worf	Trust integrity, threat detection	`security_officer`

Operations Department¶

Chief: O'Brien (OperationsAgent)

Agent	Callsign	Role	Pool
OperationsAgent	O'Brien	Resource management, scheduling, watch rotation	`operations_officer`

System Agents (conditional)¶

Pool	Purpose	When Active
`skills`	Dynamic skill execution (`SkillBasedAgent`)	Self-mod enabled
`designed_*`	Self-designed agents (`CognitiveAgent` subclasses)	Created at runtime

Test Agent¶

A CorruptedFileReaderAgent deliberately returns fabricated data to verify that the consensus layer detects and rejects it.
