v0.19.1: Advanced Agent Patterns ✅

Higher-level agent architectures built on the v0.18.0 orchestration primitives. Closes the "Advanced patterns" competitive gap. Each pattern is a standalone class — they wire up the AgentGraph topology for you.

PlanAndExecute Agent

from selectools.patterns import PlanAndExecuteAgent

agent = PlanAndExecuteAgent(
    planner=planner_agent,
    executors={"research": researcher, "write": writer, "review": reviewer},
)
result = agent.run("Write a technical blog post about vector databases")
# Planner creates structured plan → executors handle each step → result aggregated

ReflectiveAgent

from selectools.patterns import ReflectiveAgent

agent = ReflectiveAgent(
    actor=writer_agent,
    critic=reviewer_agent,
    max_reflections=3,
    stop_condition="approved",
)
result = agent.run("Draft a press release")
# Actor produces draft → Critic evaluates → Actor revises → repeat until approved

Debate Pattern

from selectools.patterns import DebateAgent

agent = DebateAgent(
    agents={"optimist": optimist_agent, "skeptic": skeptic_agent},
    judge=judge_agent,
    max_rounds=3,
)
result = agent.run("Should we adopt microservices?")
# Agents argue positions → Judge synthesizes final answer

TeamLead Pattern

from selectools.patterns import TeamLeadAgent

agent = TeamLeadAgent(
    lead=lead_agent,
    team={"analyst": analyst, "engineer": engineer, "writer": writer},
    delegation_strategy="dynamic",  # or "sequential", "parallel"
)
result = agent.run("Investigate and fix the billing discrepancy")
# Lead delegates tasks, reviews work, coordinates handoffs

Expanded Eval Suite (50 evaluators, up from 39)

11 new evaluators across two categories:

New deterministic (+8): ReadabilityEvaluator, AgentTrajectoryEvaluator, ToolEfficiencyEvaluator, SemanticSimilarityEvaluator, MultiTurnCoherenceEvaluator, JsonSchemaEvaluator, KeywordDensityEvaluator, ForbiddenWordsEvaluator

New LLM-as-judge (+4): FactConsistencyEvaluator, CustomRubricEvaluator, AnswerAttributionEvaluator, StepReasoningEvaluator

Feature	Status	Impact	Effort
PlanAndExecute	✅	High	Medium
ReflectiveAgent	✅	High	Medium
Debate	✅	Medium	Medium
TeamLead	✅	Medium	Medium
50 evaluators	✅	High	Medium

Quality Infrastructure

Ralph loop — autonomous hunt-and-fix convergence system (scripts/ralph_bug_hunt.sh, /ralph-bug-hunt skill)
Bandit in CI — security scan job on every push
Property-based tests — Hypothesis suite for structural invariants
Thread-safety smoke suite — 10-thread × 20-op concurrency tests
Production simulations — 16 integration tests covering memory pressure, provider failover, tool errors, concurrent load

v0.19.2: Enterprise Hardening ✅

Focus: Production readiness and developer trust signals before the Visual Agent Builder in v0.20.0.

Enterprise Hardening

Feature	Status	Impact	Effort
Security audit (bandit + manual nosec review)	✅	High	Medium
Stability markers (`@stable`, `@beta`, `@deprecated`)	✅	Medium	Small
Deprecation policy (2-version window, `docs/DEPRECATION_POLICY.md`)	✅	Medium	Small
Compatibility matrix (Python × provider SDK × optional deps)	✅	Medium	Small
SBOM (`sbom.json` via CycloneDX, published in repo)	✅	Low	Small
Enhanced trace viewer (`trace_to_html()` waterfall HTML)	✅	High	Medium

Quality Infrastructure

Feature	Status	Impact	Effort
Property-based tests (Hypothesis)	✅	High	Medium
Thread-safety smoke suite	✅	High	Medium
Production simulations (5 new)	✅	High	Medium

v0.19.3: Stability Markers Applied ✅

Focus: Apply @stable and @beta markers to every public symbol in the library, completing the stability annotation work started in v0.19.2.

Stable APIs (60+ symbols)

Core types, providers, agent, memory, tools, evals, guardrails, sessions, knowledge, cache, cancellation, token estimation, analytics, audit — all marked @stable. Breaking changes to these require a major version bump.

Beta APIs (30+ symbols)

Orchestration (AgentGraph, SupervisorAgent), pipelines (Pipeline, @step, parallel, branch), patterns (PlanAndExecuteAgent, ReflectiveAgent, DebateAgent, TeamLeadAgent), and composition (compose) — marked @beta. These may change in a minor release.

Introspection

from selectools import Agent, AgentGraph, PlanAndExecuteAgent
print(Agent.__stability__)              # "stable"
print(AgentGraph.__stability__)         # "beta"
print(PlanAndExecuteAgent.__stability__)  # "beta"

v0.20.0: Visual Agent Builder ✅

The headline feature: a zero-install web UI for designing, testing, and exporting agent configurations. Served by selectools serve --builder — no separate app, no subscription, no desktop install required.

Why a dedicated release: LangGraph Studio is a paid desktop app. AutoGen Studio is a separate project. selectools ships a full visual builder in one command. This deserves its own announcement.

A web-based UI for designing, testing, and exporting agent configurations. Zero-install — served by selectools serve --builder.

Features:

Drag-and-drop graph builder for AgentGraph topologies
Node palette: Agent, Tool, Router (conditional), Gate (HITL), Parallel group
Visual edge wiring with routing condition editor
Per-node configuration panel (model, tools, system prompt, budget)
Live test: run the graph against real providers from the UI
Export: generates agent.yaml or Python code
Import: load existing YAML configs into the builder
Served by selectools: selectools serve --builder (zero frontend deps)
Built as self-contained HTML/JS (same pattern as playground.py)

Technical approach:

Single HTML file with embedded JS (no React, no build step)
Canvas-based graph rendering (or SVG with drag handlers)
Backend: new /builder endpoint on AgentServer
- GET /builder — serves the HTML
- POST /builder/validate — validates graph structure
- POST /builder/export — generates YAML or Python
- POST /builder/run — executes the designed graph
State stored in browser localStorage (no server state)

Why this matters:

LangGraph has LangGraph Studio (paid, desktop app)
CrewAI has no visual builder
AutoGen has AutoGen Studio (separate app)
selectools: zero-install, runs in browser, exports to YAML/Python

Feature	Status	Impact	Effort
Graph canvas (drag-drop nodes + edges)	✅	High	Large
Node configuration panel	✅	High	Medium
YAML export/import	✅	High	Small
Python code export	✅	Medium	Small
Live test execution	✅	High	Medium
Self-contained HTML (no build step)	✅	High	Medium

New Document Loaders

Add to src/selectools/rag/loaders.py as new static methods on DocumentLoader. Refactor to loaders/ subpackage with __init__.py re-exporting everything to support SaaS loaders as separate files.

Loader	Method	Dependencies	Complexity	Why it matters
CSV	`from_csv(path, content_columns, metadata_columns)`	stdlib `csv`	Small	Most common structured data format
JSON/JSONL	`from_json(path, text_field)` / `from_jsonl(...)`	stdlib `json`	Small	Standard for API responses, logs, datasets
HTML	`from_html(path_or_content, extract_text=True)`	`beautifulsoup4` (optional)	Small	Web scraping output, saved pages
URL	`from_url(url, timeout=30)`	`requests` + `beautifulsoup4`	Small	Direct URL-to-document (2nd most requested after PDF)
Markdown w/ Frontmatter	`from_markdown(path)`	`pyyaml` (optional)	Small	Static sites, docs, wikis
Google Drive	`from_google_drive(file_id, credentials)`	`google-api-python-client`	Medium	Most-used enterprise doc platform
Notion	`from_notion(page_id, api_key)`	`requests` (existing)	Medium	2nd most-requested SaaS loader
GitHub	`from_github(repo, path, branch, token)`	`requests` (existing)	Small	Developer docs and code
SQL Database	`from_sql(connection_string, query)`	`sqlalchemy` (optional)	Medium	Enterprise data in databases

New Vector Stores

New files in src/selectools/rag/stores/. Each follows the same pattern as chroma.py: inherit VectorStore, implement add_documents, search, delete, clear, lazy-import the dependency. Register in VectorStore.create() factory.

Store	File	Dependencies	Complexity	Why it matters
FAISS	`faiss.py`	`faiss-cpu`	Medium	De facto standard for local high-perf vector search (millions of vectors)
Qdrant	`qdrant.py`	`qdrant-client`	Medium	Fastest-growing vector DB, excellent filtering, cloud + self-hosted
pgvector	`pgvector.py`	`psycopg2-binary`	Medium	Use existing PostgreSQL — no new database needed
Weaviate	`weaviate.py`	`weaviate-client`	Medium	Popular cloud vector DB with GraphQL API
Redis Vector	`redis.py`	`redis` (existing)	Medium	Leverages existing Redis connection from `cache_redis.py`

New Toolbox Modules

New files in src/selectools/toolbox/. Follow @tool decorator pattern, register in get_all_tools() and get_tools_by_category().

Module	Tools	Dependencies	Complexity	Why it matters
`**code_tools.py`	`execute_python`, `execute_shell`	stdlib `subprocess`	Medium	#1 most-used tool in agent frameworks
`search_tools.py`	`google_search`, `duckduckgo_search`	`duckduckgo_search` (optional)	Small-Medium	#2 most-used tool category
`github_tools.py`	`create_issue`, `list_issues`, `create_pr`, `get_file_contents`	`requests` (existing)	Medium	Developer workflow automation
`db_tools.py`	`query_database`, `list_tables`, `describe_table`	`sqlalchemy` (optional)	Medium	Enterprise data access

Dependency Management

All new dependencies are optional and lazy-imported. Add to pyproject.toml:

[project.optional-dependencies]
rag = [
    # existing deps ...
    "beautifulsoup4>=4.12.0",
    "faiss-cpu>=1.7.0",
    "qdrant-client>=1.7.0",
    "psycopg2-binary>=2.9.0",
    "weaviate-client>=4.0.0",
]

Individual stores/loaders remain installable a la carte: pip install selectools faiss-cpu works without the full [rag] group.

Backlog (Unscheduled — Priority Ordered)

Research basis: Competitive analysis of Agno (39k stars), PraisonAI (6.9k stars), and Superagent (6.5k stars) conducted 2026-04-10.

Strategic thesis: selectools wins on depth (50 evals, 7 vector stores, graph orchestration, pattern agents). Close the breadth gap cheaply, own the "production-ready" narrative, adopt the emerging A2A standard.

Reorganized 2026-06-12 against the v0.26.0 codebase: 11 of the 13 original P0–P2 items have shipped. Shipped items moved to the ledger below; the open remainder is re-prioritized for the post-1.0 release train.

Shipped from this backlog

Item	Shipped	Where
Tool-call loop detection (3 detectors, two-tier response)	v0.22.0	`loop_detection.py`, `docs/modules/LOOP_DETECTION.md`
Agentic memory — `remember` tool	v0.16.0	`toolbox/memory_tools.py` (auto-injected with `knowledge_memory`)
Agent-as-API (production REST, auth, SSE)	v0.24.0 (#68)	`serve/api.py`
LiteLLM provider (100+ models)	v0.24.0 (#74)	`providers/litellm_provider.py`
Cost-optimized model router	v0.24.0 (#75)	`providers/router.py`
A2A protocol (server + client + agent cards)	v0.24.0 (#76)	`a2a/`
Toolbox expansion to 48 tools (calculator, email, PDF, Slack, Notion, Linear)	v0.24.0 (#77)	`toolbox/`
Tool result compression	v0.25.0 (#87)	`ToolConfig.compress_results`, `agent/_tool_executor.py`
Session history search (FTS across 4 backends)	v0.24.0 (#79)	`sessions.py` `SessionStore.search()`
Memory tiering / auto-promotion (`UnifiedMemory`, standalone)	v0.24.0 (#78)	`unified_memory.py`
Agent-level HITL / approval	v0.25.0 (#88)	`ToolConfig.require_approval` + `approval_handler`
Planning-as-config	v0.25.0 (#86)	`AgentConfig.planning` (`PlanningConfig`)
Agentic memory — `recall` tool	v0.27.0 (#109)	`toolbox/memory_tools.py` `make_recall_tool` (auto-injected with `remember`)
UnifiedMemory AgentConfig wiring	v0.27.0 (#111)	`MemoryConfig(unified=True, ...)`, `agent/core.py`
Toolbox: Discord, S3, browser, image-gen (48 → 56 tools)	v0.27.0 (#110)	`toolbox/{discord,s3,browser,image}_tools.py`
Cache-rate cost support (OpenAI + Gemini)	v0.27.0 (#112)	`pricing.calculate_cost_with_cached_input`, `cached_prompt_cost`
Cron / scheduled agents	v0.27.0 (#113)	`scheduler.py` (`AgentScheduler`, `cron`, `every`)
Reasoning-as-tool	v0.27.0 (#114)	`toolbox/reasoning_tools.py` (`make_reasoning_tools`, `ReasoningTools`)
Episodic memory retention config	v0.27.0 (#111)	Delivered with the UnifiedMemory wiring — `MemoryConfig.episodic_retention_days` flows through and `add_turn` auto-prunes (tested: `test_retention_pruning`)

Shipped 2026-06-13: the four v1.1 candidates (#109-#112) plus the top two Future/Watch items (cron #113, reasoning tools #114), folded into the v1.0 train. Episodic retention config (#111) needed no separate work — the UnifiedMemory wiring already exposed and auto-applied it. gemini-embedding-2 decision: GA/recommended-for-new; default stays gemini-embedding-001 (incompatible embedding space). See CHANGELOG.md [Unreleased].

Active Queue — needs a product decision before building

The autonomously-buildable, high-conviction items are now shipped. Each remaining item carries a scoping/product call (flagged), so these wait on John's direction rather than getting built blind.

Item	Source	Decision needed	Effort
More DB backends — MongoDB (#116) + DynamoDB shipped; Firestore on demand	Agno	MongoDB + DynamoDB session stores shipped 2026-06-13. Firestore next only if there's demand (needs `google-cloud-firestore`).	Medium each
ML-based guard models	Superagent	Heuristic tier shipped: `PromptInjectionGuardrail` (2026-06-13) covers templated attacks with no model hosting. The model-based tier still needs the hosting decision: bundle a 0.6-4B model, optional extra, or external endpoint?	High
Multi-channel bot gateway	PraisonAI	Roadmap itself says "better as a separate package." In-repo module vs new package = a product/packaging call.	High
Learning system	Agno	Scope is vague (decision logging + preference tracking). Needs a concrete spec before it's buildable.	High
Shadow git checkpoints	PraisonAI	Only relevant if selectools moves toward coding-agent use cases — a direction call.	Medium
