\begin{abstract}
We present \textsc{ArcheFlow}, an open-source orchestration framework for
multi-agent software engineering that assigns \emph{archetypal roles}---derived
from Jungian analytical psychology---to LLM agents and coordinates them through
\emph{Plan--Do--Check--Act} (PDCA) quality cycles. Each of seven archetypes
(Explorer, Creator, Maker, Guardian, Skeptic, Trickster, Sage) carries a defined
cognitive virtue and a quantitatively detected \emph{shadow}---a failure mode
triggered when the virtue becomes excessive. The framework implements a
three-layer corrective action system (archetype shadows, system shadows, policy
boundaries) that detects and mitigates agent dysfunction during autonomous
operation. We describe ArcheFlow's architecture as a zero-dependency plugin for
Claude Code, detail its attention filtering, feedback routing, convergence
detection, and effectiveness scoring mechanisms, and discuss connections to
recent work on persona stability in language models
\citep{lu2026assistant}. ArcheFlow demonstrates that structured persona
assignment with shadow detection can maintain productive agent behavior across
extended autonomous sessions spanning multiple projects and quality domains
(code, prose, research). The system is publicly available under the MIT license.

\section{Introduction}
\label{sec:introduction}
The rise of agentic coding assistants---tools that autonomously write, test,
review, and commit code---has created a new class of software engineering
challenges. While individual LLM agents can produce competent code, the quality
of autonomous output degrades under conditions that are well-known from human
software teams: reviewers who rubber-stamp, architects who over-engineer,
implementers who ignore specifications, and testers who optimize for coverage
metrics rather than real defects.
These failure modes are not merely analogies. \citet{lu2026assistant}
demonstrate that language models occupy a measurable \emph{persona space} and
can drift from their trained Assistant identity during extended conversations,
particularly under emotional or philosophical pressure. Their ``Assistant
Axis''---a dominant directional component in activation space---predicts when
models will exhibit uncharacteristic behavior. If a single model drifts, a
multi-agent system where each agent maintains a distinct persona faces
compounded persona management challenges.
ArcheFlow addresses this problem by drawing on two established frameworks:
\begin{enumerate}
\item \textbf{Jungian archetypal psychology} \citep{jung1968archetypes}, which
provides a taxonomy of cognitive orientations---each with a productive
\emph{virtue} and a destructive \emph{shadow}---that map naturally onto
software engineering roles.
\item \textbf{PDCA quality cycles} \citep{deming1986out}, which provide a
convergence mechanism for iterative refinement with measurable exit criteria.
\end{enumerate}
The contribution of this paper is threefold:
\begin{itemize}
\item We present a \emph{shadow detection framework} that quantitatively
identifies agent dysfunction---not through sentiment analysis or output
classification, but through structural metrics (output length, finding ratios,
scope violations) specific to each archetype's failure mode (Section~\ref{sec:shadows}).
\item We describe \emph{attention filters} and \emph{feedback routing} mechanisms
that constrain what each agent sees and where its output flows, preventing the
information overload and echo chamber effects that plague na\"ive multi-agent
systems (Section~\ref{sec:attention}).
\item We demonstrate that PDCA convergence detection---including oscillation
analysis and divergence scoring---provides principled stopping criteria for
iterative review cycles (Section~\ref{sec:convergence}).
\end{itemize}
ArcheFlow is implemented as a zero-dependency plugin (Bash + Markdown) for
Claude Code\footnote{\url{https://claude.ai/claude-code}}, Anthropic's CLI
coding assistant. It has been used in production across a portfolio of 10--30
repositories spanning code, creative writing, and academic research.

\section{Related Work}
\label{sec:related}
\subsection{Multi-Agent Software Engineering}
Multi-agent systems for software engineering have proliferated since 2024.
\citet{hong2024metagpt} propose MetaGPT, which assigns human-like roles
(product manager, architect, engineer) to LLM agents and enforces structured
communication through Standardized Operating Procedures (SOPs). ChatDev
\citep{qian2024chatdev} simulates a virtual software company with role-playing
agents communicating through natural language chat. SWE-Agent
\citep{yang2024sweagent} focuses on single-agent benchmark performance on
GitHub issues, demonstrating that tool-augmented agents can resolve real-world
bugs.
These systems share a common limitation: roles are defined by \emph{job
descriptions} rather than \emph{cognitive orientations}. A ``product manager''
agent may behave identically to a ``tech lead'' agent when both receive the same
context, because the role boundary is semantic rather than structural. ArcheFlow
addresses this through attention filters (Section~\ref{sec:attention}) that
physically restrict what each agent perceives, ensuring that role differences
manifest in behavior rather than merely in prompts.
\subsection{Persona Stability in Language Models}
\citet{lu2026assistant} identify the ``Assistant Axis'' in LLM activation
space---a linear direction capturing the degree to which a model operates in its
default helpful mode versus an alternative persona. Their key findings are
directly relevant to multi-agent orchestration:
\begin{enumerate}
\item \textbf{Persona space is low-dimensional}: only 4--19 principal
components explain 70\% of persona variance across 275 character archetypes.
\item \textbf{Drift is predictable}: user message embeddings predict response
position along the Assistant Axis ($R^2 = 0.53$--$0.77$).
\item \textbf{Drift correlates with harm}: models are more liable to produce
harmful outputs when drifted from the Assistant identity ($r = 0.39$--$0.52$).
\end{enumerate}
ArcheFlow's shadow detection (Section~\ref{sec:shadows}) can be understood as an
\emph{application-level} analog to activation capping: where \citet{lu2026assistant}
constrain neural activations to maintain persona stability, ArcheFlow constrains
\emph{behavioral outputs} through quantitative triggers and corrective prompts.
Both approaches recognize that productive personas require active stabilization,
not merely initial assignment.
\subsection{Quality Cycles in Software Engineering}
The Plan--Do--Check--Act (PDCA) cycle, formalized by \citet{deming1986out} and
rooted in Shewhart's statistical process control \citep{shewhart1939statistical},
is the dominant quality improvement framework in manufacturing and has been
applied to software engineering through agile retrospectives and continuous
improvement. To our knowledge, ArcheFlow is the first system to apply PDCA
cycles to multi-agent LLM orchestration with formal convergence detection and
oscillation analysis.
\subsection{Jungian Archetypes in Computing}
While Jungian archetypes have been applied in user experience design
\citep{hartson2012ux}, brand strategy, and game design, their application to
AI agent systems is novel. The closest related work is in computational
creativity, where archetypal narratives have been used to structure story
generation \citep{winston2011strong}. ArcheFlow extends this to software
engineering by mapping archetypal virtues and shadows to measurable engineering
outcomes.
% ============================================================
\section{Architecture}
\label{sec:architecture}
ArcheFlow is a plugin for Claude Code that operates entirely through prompt
engineering, shell scripts, and file-based communication. It has zero runtime
dependencies beyond Bash and a compatible LLM backend.

\label{fig:pdca}
\end{figure}
\subsection{Components}
The system comprises four component types:
\begin{description}
\item[Agent personas] (\texttt{agents/*.md}): Behavioral protocols for each
archetype, defining the agent's cognitive lens, output format, and quality
criteria. Each persona is a Markdown file loaded as a system prompt.
\item[Skills] (\texttt{skills/*/SKILL.md}): Operational instructions that
Claude Code follows to orchestrate the PDCA cycle. The core \texttt{run} skill
(466 lines) is self-contained---it encodes the complete orchestration protocol
including workflow selection, agent spawning, attention filtering, convergence
checking, and exit decisions.
\item[Library scripts] (\texttt{lib/*.sh}): Ten Bash scripts handling
infrastructure concerns: JSONL event logging, git operations (per-phase
commits, branch management, rollback), cross-run memory, progress tracking,
effectiveness scoring, and run replay.
\item[Hooks] (\texttt{hooks/}): Session-start hook that auto-activates
ArcheFlow and injects the domain detection logic.
\end{description}
\subsection{Execution Modes}
ArcheFlow provides three execution modes optimized for different use cases:
\begin{description}
\item[Sprint] (\texttt{/af-sprint}): Queue-driven parallel dispatch. Reads a
priority-ordered task queue, spawns 3--5 agents across different projects
simultaneously, collects results, commits, and starts the next batch. Designed
for throughput over ceremony.
\item[Review] (\texttt{/af-review}): Guardian-led post-implementation review
on existing diffs, branches, or commit ranges. No planning or implementation
orchestration---pure quality analysis.
\item[Run] (\texttt{/af-run}): Full PDCA orchestration for complex tasks
requiring structured exploration, design, implementation, and multi-perspective
review.
\end{description}
\subsection{Domain Adaptation}
ArcheFlow adapts its terminology and quality criteria based on domain detection:
\texttt{code} (diffs, tests, security), \texttt{writing} (voice consistency,
dialect authenticity, narrative structure), and \texttt{research} (source quality,
argument coherence, citation accuracy). Domain is auto-detected from project
contents or specified in configuration.
% ============================================================
\section{The Seven Archetypes}
\label{sec:archetypes}
Each archetype embodies a cognitive orientation with a defined virtue (productive
mode) and shadow (destructive mode). \Cref{tab:archetypes} summarizes the
complete taxonomy.
\begin{table}[t]
\centering
\caption{The seven ArcheFlow archetypes with their PDCA phase assignments,
cognitive virtues, and shadow failure modes.}
\label{tab:archetypes}
\begin{tabular}{@{}llllll@{}}
\toprule
\textbf{Archetype} & \textbf{Phase} & \textbf{Virtue} & \textbf{Shadow} & \textbf{Model Tier} \\
\midrule
Explorer & Plan & Contextual Clarity & Rabbit Hole & Haiku \\
Creator & Plan & Decisive Framing & Over-Architect & Sonnet \\
Maker & Do & Execution Discipline & Rogue & Sonnet \\
Guardian & Check & Threat Intuition & Paranoid & Sonnet \\
Skeptic & Check & Assumption Surfacing & Paralytic & Haiku \\
Trickster & Check & Adversarial Creativity & False Alarm & Haiku \\
Sage & Check & Maintainability Judgment & Bureaucrat & Haiku \\
\bottomrule
\end{tabular}
\end{table}
The archetype--shadow pairing is not metaphorical; it is the core mechanism
for maintaining agent quality. The virtue describes \emph{what} the archetype
contributes; the shadow describes what happens when that contribution becomes
excessive. An Explorer who never stops researching (Rabbit Hole) delays the
entire pipeline. A Guardian who rejects everything (Paranoid) prevents any
code from shipping.
\subsection{Cost-Aware Model Assignment}
Not all archetypes require the same model capability. Analytical tasks
(exploration, assumption checking, code quality review) can be performed by
cheaper models (Haiku), while creative tasks (architecture design,
implementation, security analysis) benefit from more capable models (Sonnet).
This tiered assignment reduces per-run costs by 40--60\% compared to using the
most capable model for all agents, with no observed quality degradation in
analytical roles.
% ============================================================
\section{Shadow Detection and Corrective Action}
\label{sec:shadows}
\subsection{Archetype Shadows}
Shadow detection is \emph{quantitative, not sentiment-based}. Each archetype has
a specific trigger condition derived from structural properties of its output:
\begin{table}[h]
\centering
\caption{Shadow detection triggers. Each trigger is evaluated automatically
after the agent completes.}
\label{tab:shadows}
\begin{tabular}{@{}lll@{}}
\toprule
\textbf{Archetype} & \textbf{Shadow} & \textbf{Trigger} \\
\midrule
Explorer & Rabbit Hole & Output $> 2000$ words without Recommendation section \\
Creator & Over-Architect & $> 2$ new abstractions for a single feature \\
Maker & Rogue & No tests in changeset, or files outside proposal scope \\
Guardian & Paranoid & CRITICAL:WARNING ratio $> 2{:}1$, or zero approvals \\
Skeptic & Paralytic & $> 7$ challenges with $< 50\%$ having alternatives \\
Trickster & False Alarm & Findings in untouched code, or $> 10$ total findings \\
Sage & Bureaucrat & Review length $> 2\times$ code change length \\
\bottomrule
\end{tabular}
\end{table}
The escalation protocol follows a three-strike pattern:
\begin{enumerate}
\item \textbf{First detection}: Inject a correction prompt that names the
shadow and redirects the agent toward its virtue.
\item \textbf{Second detection} (same shadow, same run): Replace the agent
with a fresh instance.
\item \textbf{Third detection}: Escalate to the user for manual intervention.
\end{enumerate}
\subsection{System Shadows}
Beyond individual archetype dysfunction, ArcheFlow monitors for
\emph{system-level} failure modes:
\begin{description}
\item[Echo Chamber]: Multiple reviewers produce identical findings, suggesting
they are confirming each other rather than applying independent judgment.
Detected when $> 60\%$ of findings across reviewers share the same
file-and-category tuple.
\item[Tunnel Vision]: All findings cluster in a single file or module while
the changeset spans multiple. Detected when $> 80\%$ of findings target
$< 20\%$ of changed files.
\item[Scope Creep]: Maker modifies files not mentioned in the Creator's
proposal. Detected by comparing \texttt{do-maker-files.txt} against the
proposal's file list.
\end{description}
\subsection{Policy Boundaries}
The third layer enforces operational limits:
\begin{itemize}
\item \textbf{Budget enforcement}: per-run token limits with per-agent
tracking.
\item \textbf{Cycle limits}: maximum PDCA iterations (1/2/3 for
fast/standard/thorough).
\item \textbf{Checkpoint frequency}: mandatory progress saves to prevent
lost work on interruption.
\end{itemize}
\subsection{Connection to the Assistant Axis}
The shadow detection framework addresses the same fundamental problem identified
by \citet{lu2026assistant}: models drift from productive personas during
extended operation. Where their work identifies drift in activation space and
proposes activation capping as a mitigation, ArcheFlow operates at the
\emph{behavioral} level---detecting drift through output structure rather than
internal representations, and correcting through prompt injection rather than
activation manipulation.
This application-level approach has a practical advantage: it requires no access
to model internals and works with any LLM backend, including API-only models
where activation-level interventions are impossible. The tradeoff is that
behavioral detection is necessarily coarser than activation-level measurement
and can only detect drift after it manifests in output, not before.
% ============================================================
\section{Attention Filters and Information Flow}
\label{sec:attention}
A key design principle is that each agent receives \emph{only the information
relevant to its role}. This is implemented through \emph{attention filters}---rules
governing which artifacts from prior phases are injected into each agent's
context.
\begin{table}[h]
\centering
\caption{Attention filter matrix. Each agent receives only the artifacts marked
with \checkmark.}
\label{tab:attention}
\begin{tabular}{@{}lccccc@{}}
\toprule
\textbf{Agent} & \textbf{Task} & \textbf{Explorer} & \textbf{Creator} & \textbf{Diff} & \textbf{Reviews} \\
\midrule
Explorer & \checkmark & & & & \\
Creator & \checkmark & \checkmark & & & \\
Maker & \checkmark & & \checkmark & & \\
Guardian & & & (risks) & \checkmark & \\
Skeptic & & & \checkmark & & \\
Sage & & & \checkmark & \checkmark & \\
Trickster & & & & \checkmark & \\
\bottomrule
\end{tabular}
\end{table}
The rationale for attention filtering is twofold:
\begin{enumerate}
\item \textbf{Independence}: Reviewers who see each other's findings tend to
converge on a shared narrative rather than applying independent judgment. By
isolating reviewer inputs, ArcheFlow ensures that each reviewer contributes a
genuinely distinct perspective.
\item \textbf{Focus}: An agent given everything tends to address everything,
producing diluted analysis. The Trickster, for example, receives \emph{only}
the diff---no design rationale, no risk analysis---forcing it to evaluate the
code purely on its own terms.
\end{enumerate}
In PDCA cycle 2+, the feedback from the Act phase is routed selectively:
Creator-routed issues go to the Creator, Maker-routed issues go to the Maker.
Neither sees the other's feedback, preventing defensive responses to criticism
that was directed elsewhere.
% ============================================================
\section{Feedback Routing}
\label{sec:routing}
When the Check phase identifies issues, the Act phase must decide where to route
each finding for the next cycle. ArcheFlow uses a deterministic routing table
based on the source archetype and finding category:
\begin{table}[h]
\centering
\caption{Feedback routing table. Findings are routed to the agent best equipped
to address them, preventing cross-contamination.}
\label{tab:routing}
\begin{tabular}{@{}llll@{}}
\toprule
\textbf{Source} & \textbf{Category} & \textbf{Routes To} & \textbf{Rationale} \\
\midrule
Guardian & security, breaking-change & Creator & Design must change \\
Guardian & reliability, dependency & Creator & Architectural decision \\
Skeptic & design, scalability & Creator & Assumptions need revision \\
Sage & quality, consistency & Maker & Implementation refinement \\
Sage & testing & Maker & Test gap, not design flaw \\
Trickster & reliability (design flaw) & Creator & Needs redesign \\
Trickster & reliability (test gap) & Maker & Needs more tests \\
\bottomrule
\end{tabular}
\end{table}
The disambiguation principle: if fixing the issue requires changing the
\emph{approach}, route to Creator. If it requires changing the \emph{code within
the existing approach}, route to Maker. Findings that persist across two
consecutive cycles are escalated to the user rather than cycled indefinitely.
% ============================================================
\section{Convergence Detection}
\label{sec:convergence}
\subsection{Convergence Score}
In PDCA cycle 2+, ArcheFlow compares current findings against the previous cycle
and classifies each as \textsc{New}, \textsc{Resolved}, \textsc{Persistent}, or
\textsc{Regressed}. The convergence score is:
\begin{equation}
C = \frac{|\textsc{Resolved}|}{|\textsc{Resolved}| + |\textsc{New}| + |\textsc{Regressed}|}
\label{eq:convergence}
\end{equation}
\begin{table}[h]
\centering
\caption{Convergence score interpretation and corresponding actions.}
\label{tab:convergence}
\begin{tabular}{@{}lll@{}}
\toprule
\textbf{Score Range} & \textbf{Status} & \textbf{Action} \\
\midrule
$C > 0.8$ & Converging & Continue if cycles remain \\
$0.5 \leq C \leq 0.8$ & Stalling & Continue with caution \\
$C < 0.5$ & Diverging & Stop if 2 consecutive diverging cycles \\
$C = 0$ & Stuck & Stop immediately \\
\bottomrule
\end{tabular}
\end{table}
\subsection{Oscillation Detection}
A finding is \emph{oscillating} if it was present in cycle $n-2$, absent in
cycle $n-1$, and present again in cycle $n$. Two or more oscillating findings
trigger an immediate stop with escalation to the user, as oscillation indicates
a fundamental tension in the review criteria that automated cycles cannot
resolve.
\subsection{Adaptive Workflow Escalation}
Convergence detection interacts with workflow selection through Rule A1: if a
\texttt{fast} workflow and Guardian finds $\geq 2$ CRITICAL findings, the next
cycle escalates to \texttt{standard} (adding Skeptic and Sage reviewers). Once
escalated, the workflow remains escalated for the duration of the run.
Conversely, Rule A2 provides a \emph{fast-path}: if Guardian finds zero CRITICAL
and zero WARNING findings, remaining reviewers are skipped entirely, and the
system proceeds directly to Act. This optimization reduces the cost of runs
where the Maker's implementation is clean.
% ============================================================
\section{Evidence Validation}
\label{sec:evidence}
Reviewer findings are subject to evidence validation before they influence
routing decisions. A CRITICAL or WARNING finding is downgraded to INFO if:
\begin{itemize}
\item It uses \emph{banned hedging phrases} without supporting evidence:
``might be'', ``could potentially'', ``appears to'', ``seems like'', ``may not''.
\item It contains \emph{no evidence}: no command output, code citation, line
reference, or reproduction steps.
\end{itemize}
This mechanism addresses a well-known failure mode of LLM reviewers: generating
plausible-sounding but unsupported concerns. By requiring evidence for
high-severity findings, ArcheFlow forces reviewers to ground their analysis in
the actual changeset rather than speculation.
Downgrades are tracked in the event log but do \emph{not} modify the original
artifact files, preserving the complete reviewer output for post-run analysis.
% ============================================================
\section{Effectiveness Scoring}
\label{sec:effectiveness}
After each completed run, ArcheFlow scores review archetypes across five
dimensions:
\begin{table}[h]
\centering
\caption{Effectiveness scoring dimensions and their weights.}
\label{tab:effectiveness}
\begin{tabular}{@{}lp{7cm}r@{}}
\toprule
\textbf{Dimension} & \textbf{Description} & \textbf{Weight} \\
\midrule
Signal-to-noise & Ratio of useful findings to total findings & 0.30 \\
Fix rate & Fraction of findings that led to applied fixes & 0.25 \\
Cost efficiency & Useful findings per dollar of model inference cost & 0.20 \\
Accuracy & Fraction not contradicted by other reviewers & 0.15 \\
Cycle impact & Whether findings contributed to cycle exit decision & 0.10 \\
\bottomrule
\end{tabular}
\end{table}
Scores accumulate in a cross-run memory file
(\texttt{.archeflow/memory/effectiveness.jsonl}). After 10+ completed runs,
the system recommends model tier changes (e.g., promoting a Haiku-tier reviewer
to Sonnet if its signal-to-noise is consistently high) and, in extreme cases,
archetype removal for persistently low-scoring reviewers.
% ============================================================
\section{Cross-Run Memory}
\label{sec:memory}
ArcheFlow maintains a lesson-learning system that persists across runs. When
recurring findings are detected---the same category of issue appearing in
multiple runs---the system stores a lesson and injects it into future agents
as additional context.
Lessons decay over time: each lesson has a relevance counter that increments on
reuse and decrements on irrelevance. Lessons that fall below a threshold are
archived rather than injected, preventing the accumulation of stale guidance.
The memory system also performs regression detection: if a previously resolved
issue reappears, it is flagged as a regression with higher priority than a
fresh finding.
% ============================================================
\section{Implementation}
\label{sec:implementation}
ArcheFlow is implemented in approximately 6,700 lines across three layers:
\begin{itemize}
\item \textbf{Skills} (19 Markdown files, $\sim$2,500 lines): Operational
instructions for Claude Code, written as imperative protocols. The core
\texttt{run} skill encodes the complete PDCA orchestration in 466 lines.
\item \textbf{Agent personas} (7 Markdown files, $\sim$700 lines): Behavioral
protocols defining each archetype's cognitive lens, output format, and
self-review checklist.
\item \textbf{Library scripts} (10 Bash scripts, $\sim$3,500 lines): Event
logging, git operations, memory management, progress tracking, effectiveness
scoring, and run replay.
\end{itemize}
The system uses no database, no API server, and no runtime dependencies beyond
Bash 4+ and a Claude Code installation. All state is stored in JSONL event logs
and Markdown artifact files. This zero-dependency architecture was a deliberate
design choice: orchestration infrastructure that itself requires complex setup
and maintenance undermines the autonomy it is supposed to enable.
\subsection{Git Integration}
ArcheFlow creates per-phase commits, enabling fine-grained rollback. The Maker
operates in a git worktree---an isolated working copy---so its changes do not
affect the main branch until explicitly merged. If post-merge tests fail, the
system auto-reverts the merge and cycles back with ``integration test failure''
feedback.
\subsection{Run Replay}
All orchestration decisions are logged as \texttt{decision.point} events,
enabling post-hoc analysis. The replay system provides:
\begin{itemize}
\item \textbf{Timeline view}: chronological sequence of all decisions with
confidence scores.
\item \textbf{Weighted what-if}: re-evaluation of the ship/block outcome
using different reviewer weights, answering questions like ``would the outcome
have changed if we weighted Guardian 2x and Sage 0.5x?''
\item \textbf{Cross-run comparison}: side-by-side analysis of decision
patterns across runs.
\end{itemize}
% ============================================================
\section{Multi-Domain Application}
\label{sec:domains}
ArcheFlow's archetype system extends beyond code. The framework has been
deployed across three domains:
\subsection{Software Engineering}
The primary domain. Archetypes map to standard engineering roles: Explorer
performs codebase research, Creator designs architecture, Maker writes code,
and the Check-phase archetypes review for security (Guardian), design flaws
(Skeptic), edge cases (Trickster), and overall quality (Sage).
\subsection{Creative Writing}
In writing mode, the same archetype structure applies with adapted quality
criteria. Custom archetypes (story-explorer, story-sage) replace or augment
the defaults. The framework integrates with Colette, a voice profiling system
that maintains consistent authorial voice across chapters. Quality gates check
for voice consistency, dialect authenticity, and narrative structure rather
than test coverage and security.
\subsection{Academic Research}
In research mode, quality criteria shift to source quality, argument coherence,
citation accuracy, and methodological rigor. The Guardian reviews for logical
fallacies and unsupported claims rather than security vulnerabilities.
% ============================================================
\section{Discussion}
\label{sec:discussion}
\subsection{Archetypes vs. Role Descriptions}
The key distinction between ArcheFlow's approach and prior multi-agent systems
is the \emph{shadow} mechanism. A role description tells an agent what to do;
an archetype tells an agent what to do \emph{and what doing too much of it
looks like}. This bidirectional specification creates a bounded operating
range for each agent, preventing the unbounded optimization that leads to
dysfunction.
The connection to \citet{lu2026assistant}'s persona axis is instructive.
They show that model personas exist on a continuum, with the Assistant identity
at one extreme and theatrical/mystical identities at the other. ArcheFlow's
archetypes deliberately position agents \emph{away} from the default Assistant
toward specific cognitive orientations---but the shadow mechanism prevents them
from drifting too far, maintaining a productive operating range analogous to
what \citeauthor{lu2026assistant} achieve through activation capping.
\subsection{Limitations}
\begin{enumerate}
\item \textbf{No activation-level control}: ArcheFlow operates purely at the
prompt level. It cannot detect persona drift before it manifests in output,
unlike activation-level approaches \citep{lu2026assistant}.
\item \textbf{Single LLM backend}: The current implementation targets Claude
Code. While the architectural principles are model-agnostic, the skill and
hook system is specific to Claude Code's plugin API.
\item \textbf{Evaluation methodology}: We have not conducted controlled
experiments comparing ArcheFlow's output quality against baselines (single-agent,
role-based multi-agent without shadows, PDCA without archetypes). The system
has been evaluated through production use across real projects, which
demonstrates practical utility but not causal attribution.
\item \textbf{Shadow trigger thresholds}: The quantitative thresholds
(e.g., 2000 words for Rabbit Hole, ratio $> 2{:}1$ for Paranoid) were
determined empirically through iterative use and may not generalize across
all codebases and domains.
\end{enumerate}
\subsection{Future Work}
\begin{enumerate}
\item \textbf{Activation-level integration}: Combining behavioral shadow
detection with the Assistant Axis measurement from \citet{lu2026assistant}
could provide earlier and more reliable drift detection, particularly for
open-weight models where activations are accessible.
\item \textbf{Controlled evaluation}: A systematic comparison across standard
benchmarks (SWE-bench, HumanEval) would establish whether the archetype +
PDCA approach provides measurable quality improvements over simpler
orchestration strategies.
\item \textbf{Archetype discovery}: Rather than hand-designing archetypes,
the persona space analysis from \citet{lu2026assistant} could be used to
identify \emph{natural} cognitive orientations that models adopt, potentially
revealing useful archetypes that human intuition would not suggest.
\item \textbf{Cross-model persona stability}: Investigating whether shadow
triggers calibrated for one model family transfer to others, or whether
per-model calibration is necessary.
\end{enumerate}

\section{Conclusion}
\label{sec:conclusion}
ArcheFlow demonstrates that multi-agent LLM orchestration benefits from
structured persona management---not just telling agents \emph{what to do},
but actively monitoring and correcting \emph{how they do it}. The combination
of Jungian archetypes (providing a principled taxonomy of cognitive virtues and
their failure modes) with PDCA quality cycles (providing convergence guarantees
and principled stopping criteria) produces an orchestration framework that
maintains productive agent behavior across extended autonomous sessions.
The shadow detection mechanism---quantitative triggers for archetype-specific
dysfunction---addresses the same persona stability challenge identified by
\citet{lu2026assistant} at the application level, requiring no access to model
internals and working with any LLM backend. While coarser than activation-level
approaches, behavioral shadow detection is practical, interpretable, and
immediately deployable.
