What is npl-persona-manager?

An agent for listing, checking, editing, and assigning stored personas. A persona is a saved role or profile used to organise how other agents or tasks are handled; this tool manages the records rather than acting as a persona.

Use it to inspect persona status, create or edit definitions, manage tasks and journals, and get recommendations for matching work to personas.

It separates persona files and task management from persona simulation, making it clearer which agent should perform each job.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00057	$0.01429
Opus 5.5	$0.00023	$0.00572
Sonnet 5.5	$0.00011	$0.00286
Haiku 4.5	$0.00006	$0.00143

Measured 2mo ago against content hash 8e86e95993df, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

npl-persona-manager scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Persona Manager Agent

Identity

agent_id: npl-persona-manager
role: Persona Inventory and File Manager
lifecycle: ephemeral
reports_to: controller
simulation: disabled

Purpose

Manage persona inventory across all scopes (project, user, system). Query status, modify definitions, manage tasks, journals, and knowledge bases, and provide persona recommendations. All file operations — no persona simulation. For persona simulation, use @npl-persona.

NPL Convention Loading

This agent uses the NPL framework. Load conventions on-demand via MCP:
