intelligence-suite 0.13.0

Modular knowledge retrieval suite: code, docs, APIs — all on-premise

IntelligenceSuite

Retrieve enterprise knowledge in seconds, not hours.

A modular RAG suite for on-premise environments. Index your codebase and company documents, then query them in natural language with precise source citations.

code + docs  →  parse  →  chunks  →  embed  →  ChromaDB  →  REST API  →  natural-language answers

Zero mandatory cloud. Zero lock-in. On-premise by default — Ollama for inference, ChromaDB embedded for storage.

Overview

IntelligenceSuite is built in two layers: a shared engine (intelligence_core) that implements the entire RAG pipeline once, and a set of domain modules (Code, Doc, Mentor, Skill, Agent, Proposal) that reuse that engine and only add domain-specific parsing and an API surface.

Most modules answer questions over your knowledge base via the standard pipeline (steps 1–2). ProposalIntelligence is the exception — it uses the same engine for retrieval but follows a style-grounded flow (step 3) to write answers in your house tone.

1 · Ingest — offline CLI or on-demand API/UI

Code, documents and team practices are parsed into a unified chunk schema, embedded into vectors, and stored in per-domain ChromaDB collections. The same pipeline runs whether it is driven by the offline CLIs or the opt-in on-demand routes — and either way indexing is idempotent (chunks are re-embedded only when their checksum changed).

2 · Query — live, per request

Every question is routed, retrieved, reranked, optionally expanded via the dependency graph, then answered by the LLM with source citations — escalating to Claude only when local confidence is too low.

3 · Style-grounded answering — ProposalIntelligence

RFPs and vendor questionnaires don't need facts retrieved — they need answers written in a specific corporate tone, grounded in how you've answered before. This module embeds the question of each past Q&A pair (not the whole text), so a new question matches similar past ones; the retrieved pairs become few-shot style exemplars for the LLM. A mode controls how closely the answer sticks to the corpus.

Operational surface — ingest & export

Beyond query, every server exposes two opt-in operational capabilities — index content without touching the CLI, and download a conversation or answer set as a file.

Quick start

Prerequisites

# Ollama (local inference — no GPU required for embedding)
# Download from https://ollama.com, then:
ollama serve
ollama pull nomic-embed-text      # embedding model
ollama pull qwen2.5-coder:7b      # generation model (or any other)

Option A — Launcher (recommended)

One command starts a dashboard that manages every module.

pip install intelligence-suite
is-launch          # opens http://localhost:8079 in your browser

Each card has ▶ Start / ■ Stop / Apri → controls (start, wait for the green dot, then open the chat UI). The header ▶ Avvia tutto starts every server at once.

First time? Index your content before starting the servers:

ci-parse /path/to/repo && ci-embed   # CodeIntelligence (one-time)
di-ingest /path/to/docs && di-embed  # DocIntelligence  (one-time)
mi-ingest ./practices                # MentorIntelligence (one-time)

Option B — Individual servers

ci-parse /path/to/your/repo       # parse → chunks.jsonl        (seconds)
ci-embed                           # embed → ChromaDB            (one-time, ~20-40 min CPU)
ci-serve                           # REST API + Chat UI → http://localhost:8080

ci-embed is slow the first time (every chunk is sent to the embedding model). ChromaDB persists the result to ~/.intelligence_suite/chroma (absolute path — safe from any working directory). Subsequent restarts are instant.

Chat UI

Open any running server's URL — the interface loads instantly:

• Responses stream word by word (SSE) · multi-conversation sidebar with per-module history in localStorage · source citations as chips (file · type · score) · live status / chunk count / backend
• Export the conversation to Markdown / HTML / PDF from the top bar
• On-demand ingest panel (when IS_INGEST_ENABLED) to index a path or upload files
• Zero extra dependencies — served directly from the RAG server

Query via REST

curl -X POST http://localhost:8080/api/v1/query \
  -H "Content-Type: application/json" \
  -d '{"question": "Where is authentication handled?"}'

{
  "answer": "Authentication is handled in auth/jwt.py — the verify_token function ...",
  "sources": [{"source": "auth/jwt.py", "type": "function", "score": 0.91}],
  "confidence": 0.91,
  "escalated": false,
  "backend": "ollama",
  "latency_ms": 312.4
}

No cloud, no API key, no GPU required for the default setup.

Modules

Module	Domain	Description
intelligence_core	Shared layer	Chunk schema, embedder, ChromaDB store, retriever, reranker, escalation, intent routing, ingestion, export, GraphRAG, RAGAS
CodeIntelligence	Source code	Python AST + Tree-sitter parsers for TS/Go/Java/Rust (regex fallback), YAML, SQL, MD
DocIntelligence	Company docs	PDF (3-level), DOCX, XLSX, CSV/TSV, TXT/MD ingest pipeline
MentorIntelligence	Onboarding	Adaptive onboarding — profile detection, sessions, cross-domain path
SkillIntelligence	Procedures	Step-by-step procedural guidance with cross-domain RAG (code + doc + mentor)
AgentIntelligence	Multi-hop agent	ReAct agent with tool calling (search_code/docs/practices, analyze_impact)
ProposalIntelligence	Questionnaires / RFPs	Auto-answers questionnaires in your house style, grounded in past Q&A

CodeIntelligence — source code RAG

Language	Parser	Extracts
Python	AST-based (precise)	modules, classes, methods, functions, decorators, async, call graph
TypeScript / JS	Tree-sitter¹ (regex fallback)	functions, methods, call sites
Go	Tree-sitter¹ (regex fallback)	functions, method receivers, call sites

Markdown	Heading-based	H1 / H2 / H3 sections

¹ Requires [multilang]. Without it, TS/JS and Go fall back to regex parsers automatically. Tree-sitter parsers also extract calls metadata, which powers the dependency graph ([graph]).

ci-parse /path/to/repo               # → chunks.jsonl                  (seconds)
ci-embed                              # → ~/.intelligence_suite/chroma  (slow, one-time)
ci-embed --incremental                # re-embed only new chunks
ci-serve                              # http://localhost:8080

DocIntelligence — document RAG

Format	Parser	Notes
PDF	pdfplumber → pytesseract → raw binary	3-level fallback; heading detection via y-coords
DOCX	python-docx	Heading + body sections
XLSX	openpyxl	Sheet-by-sheet tabular chunks
CSV / TSV	Built-in (stdlib csv)	Delimiter auto-detected; a schema chunk + a row-preview chunk per file
TXT / MD	Built-in	Line-based or heading-based split

di-ingest /path/to/docs              # → doc_chunks.jsonl              (seconds)
di-embed                              # → ~/.intelligence_suite/chroma  (slow, one-time)
di-serve                              # http://localhost:8081

MentorIntelligence — adaptive onboarding

Feature	Description
Profile detection	Infers seniority and specialisation from the intro message
Session management	Persistent onboarding sessions with full question history
Path builder	Generates a structured learning path from profile + company practices
Cross-domain orchestrator	Retrieves from code, doc, and mentor domains in one query
Practice ingestion	Ingest team conventions, naming guides, runbooks as mentor knowledge

mi-ingest ./practices                # ingest best practices (Markdown / TXT / YAML)
mi-serve                              # http://localhost:8082

curl -X POST http://localhost:8082/api/v1/mentor/onboard \
  -H "Content-Type: application/json" \
  -d '{"user_name": "Alice", "intro": "I am a senior Python developer, first day here."}'

The repository ships a ready-to-use practices/ folder documenting IntelligenceSuite itself — each file is split by ## headings at ingest time (one chunk per section).

SkillIntelligence — procedural guidance with RAG

Turns company procedures into interactive step-by-step sessions. Each step retrieves context from the code/doc/mentor knowledge bases before generating LLM guidance — grounded in your actual company knowledge.

si-serve                              # http://localhost:8083
si-ingest ./skill_docs                # load / list Markdown skills

curl -X POST http://localhost:8083/api/v1/skill/start \
  -H "Content-Type: application/json" \
  -d '{"skill_name": "deploy_checklist",
       "parameters": {"service_name": "api", "environment": "staging"}}'

Skills are authored in Markdown (picked up automatically at server start):

# Skill: My Deploy Checklist
> description: Guide the team through a production deploy.
> parameters: service_name (str, required), environment (str, required, enum: staging|production)

## Step 1: Pre-flight checks
**Domini:** doc, code
**Query:** pre-deploy checklist {service_name} {environment}
Verify all CI checks pass and the changelog is updated.

…or in Python by subclassing BaseSkill and dropping the file in SkillIntelligence/skills/.

Endpoint	Method	Description
/api/v1/skill/list	GET	List all registered skills
/api/v1/skill/start	POST	Start a session → first step guidance + sources
/api/v1/skill/next	POST	Advance to next step (completed: true when done)
/api/v1/skill/session/{id}	GET	Current session metadata

Sessions are stored as JSON in ~/.intelligence_suite/skill_sessions/, survive restarts, and are deleted when all steps complete.

AgentIntelligence — multi-hop ReAct agent

For questions a single retrieval can't answer ("what breaks if I change function X?"), AgentIntelligence runs a real ReAct loop: reason → call tools → observe → iterate.

Tool	Purpose
search_code / search_docs / search_practices	Semantic search over each domain
analyze_impact	Walks the reverse call graph — "what depends on this?" (requires [graph])

ai-serve                              # http://localhost:8084
curl -X POST http://localhost:8084/api/v1/agent/query \
  -H "Content-Type: application/json" \
  -d '{"question": "What breaks if I change the verify_token function?"}'

The agent is also reachable transparently through Intent Routing when a query is classified as complex multi-domain analysis.

ProposalIntelligence — answer questionnaires in your house style

Loads a corpus of past Q&A pairs (what and how you answer), then generates answers to a new questionnaire that imitate that style and stay grounded in the retrieved examples.

Mode	Behaviour
anchored	Uses only facts in the retrieved examples; says so explicitly if they don't cover the question.
commercial	May elaborate persuasively in the house tone, but specific factual claims stay consistent with the examples — never fabricated.

In both modes a guardrail forbids inventing named clients, projects, figures or certifications.

pi-ingest examples/proposal/qa_corpus.md         # → qa_chunks.jsonl
pi-embed                                          # → ChromaDB "proposal_intelligence"
pi-answer examples/proposal/questionnaire.md --mode commercial -o risposte.md
pi-serve                                          # web UI → http://localhost:8085

Multilingual matching. Questionnaires are often in Italian — give this module its own embedder via per-module override (no need to re-index code/doc):

PI_EMBED_BACKEND=st
PI_EMBED_MODEL=paraphrase-multilingual-MiniLM-L12-v2

Privacy. Real corpora can contain confidential bid data, so qa_corpus/, questionari/, qa_chunks.jsonl and risposte.md are git-ignored. Only the synthetic demo under examples/proposal/ is versioned.

---

Intent routing

Every /api/v1/query request is transparently classified before being answered — the user writes in the chat as always; the routing is invisible.

Level	When	Result
RAG	Simple factual question	Standard retrieval + LLM answer
SKILL	Procedural request ("guide me", "step by step")	SkillSession started, first step returned
AGENT	Complex multi-domain analysis	ReAct agent (enable with INTENT_AGENT_ENABLED=true)

Two-stage classification: a 0 ms keyword heuristic handles confident cases; an LLM call (~300 ms) is made only for ambiguous ones (confidence < 0.85). Any failure silently falls back to RAG. Disable entirely with INTENT_ROUTING=false.

---

On-demand ingestion (API + UI)

Besides the offline ci-embed / di-embed / pi-embed CLIs, content can be indexed on demand over HTTP and straight from the chat UI. Opt-in and off by default — when disabled the routes return 404 and behaviour is identical to before.

IS_INGEST_ENABLED=true            # default false → routes absent (404), no UI panel
IS_INGEST_ROOT=/srv/knowledge     # server-side root the path endpoint is confined to
IS_INGEST_MAX_MB=50               # per-file upload cap (413 on overflow)

The same parse+embed pipeline runs, so indexing stays idempotent: chunks are keyed by the deterministic domain::type::locator ID and re-embedded only when their checksum changed; on a full path scan, orphaned chunks are pruned. The heavy work always runs in a background thread, so the HTTP call returns at once with a job_id to poll.

Endpoint	Method	Description
/api/v1/ingest/path	POST	Index a server-side path (validated inside IS_INGEST_ROOT). Body {path, module?, incremental?} → {job_id, status}.
/api/v1/ingest/upload	POST	Index uploaded files (multipart). Per-file cap IS_INGEST_MAX_MB. Needs the [ingest] extra; absent → route not mounted.
/api/v1/ingest/status/{job_id}	GET	Poll a job (queued → running → done/error); 404 if unknown.

Each request targets the hosting server's module by default; an optional module field can retarget to any of code | doc | mentor | proposal. /health reports ingest_enabled so the chat UI shows a "📥 Indicizza contenuti" panel (server-side path for Code, file upload for the others) that submits the job and live-polls its status. All routes sit behind the same Bearer auth middleware.

curl -X POST http://localhost:8081/api/v1/ingest/upload \
     -F "files=@./report.csv" -F "files=@./spec.pdf"
# → {"job_id":"…","status":"queued","module":"doc","files":2}

curl http://localhost:8081/api/v1/ingest/status/<job_id>
# → {"status":"done","stats":{"new":2,"skipped":0,"deleted":0, …}}

---

Export

Turn a chat conversation or a set of Proposal answers into a downloadable file — POST /api/v1/export, mounted on every module server. Markdown and a standalone HTML page are stdlib (always available); PDF needs the opt-in [export] extra (fpdf2).

format	Extra	Output
markdown	(none)	text/markdown — title + ## sections + _Fonti: …_
html	(none)	standalone, escaped text/html page
pdf	[export]	application/pdf (via fpdf2); 503 if the extra is missing

curl -X POST http://localhost:8080/api/v1/export \
  -H "Content-Type: application/json" \
  -d '{"format":"markdown","title":"Conversazione",
       "sections":[{"heading":"Tu","body":"Where is auth handled?"},
                   {"heading":"Assistant","body":"In auth/jwt.py …",
                    "sources":[{"source":"auth/jwt.py"}]}]}' \
  -o conversazione.md

The response is an attachment (Content-Disposition) with the right Content-Type. An unknown format → 400; format=pdf without the extra → 503 (Markdown/HTML keep working). In the UI an "⬇︎ Esporta" menu appears in the chat top bar (active conversation) and the Proposal header (generated answers).

---

Dependency graph & GraphRAG

CodeIntelligence chunks carry calls / imports / bases metadata. The [graph] extra builds a directed dependency graph with NetworkX, persisted to ~/.intelligence_suite/graph/.

pip install "intelligence-suite[graph]"
ci-graph --stats                 # build the graph and print node/edge stats
ci-graph --top-critical 10       # the 10 most-called functions (impact hotspots)

Once the graph exists the retriever automatically performs GraphRAG: after the semantic search it expands context with structurally-related nodes (callers + callees) of the top hits. Fully optional and non-breaking — if the graph is missing or fails, retrieval proceeds unchanged.

---

RAG evaluation (RAGAS)

Measure retrieval/answer quality on four dimensions: faithfulness, answer relevancy, context precision, context recall.

pip install "intelligence-suite[eval]"
ci-eval --domain code --samples 50          # generate testset, run, score
ci-eval --domain doc --regenerate           # force-regenerate the cached testset

KPI targets: faithfulness ≥ 0.75, answer_relevancy ≥ 0.75, context_precision ≥ 0.70, context_recall ≥ 0.68. Reports are saved under ~/.intelligence_suite/eval/ with a delta vs the previous run; the command exits non-zero if any target is missed (CI-friendly).

---

Multi-project

Run several isolated knowledge bases from one installation. Set IS_PROJECT to namespace every ChromaDB collection and state directory by project.

IS_PROJECT=acme    # default "default" → identical to the single-project layout

Concern	IS_PROJECT unset (default)	IS_PROJECT=acme
Collections	code_intelligence, doc_intelligence, …	acme_code_intelligence, …
State dirs	~/.intelligence_suite/<chroma|graph|eval|skill_sessions>/	~/.intelligence_suite/acme/…

Names and paths are resolved at call time by intelligence_core/paths.py (single source of truth); nothing leaks between projects. The default value reproduces the pre-multi-project layout, so existing installs keep working with zero migration.

---

Authentication

Optional Bearer-token auth across all servers. Disabled by default. Enable it to require a shared API key on every /api/v1/* endpoint.

IS_AUTH_ENABLED=true                 # default false
IS_API_KEY=your-long-random-secret   # required when auth is enabled

curl -H "Authorization: Bearer your-long-random-secret" \
     -X POST http://localhost:8080/api/v1/query -d '{"question":"how does retrieval work?"}'

• Public paths stay open: / (UI), /health, /docs, /redoc, /openapi.json.
• A missing/wrong token on a protected path → HTTP 403 {"error":"invalid_api_key"}.
• If IS_AUTH_ENABLED=true but IS_API_KEY is empty, the server refuses to start.
• The middleware is pure ASGI, so SSE streaming is never buffered or broken.

---

Observability

Structured logging and in-memory metrics, stdlib only — opt-in, zero impact on defaults.

IS_LOG_LEVEL=INFO     # DEBUG | INFO | WARNING | ERROR   (default INFO)
IS_LOG_FORMAT=json    # json (default) | text            (text = dev-friendly)
IS_METRICS_ENABLED=true   # default false → GET /metrics returns 404

One query event is emitted per /api/v1/query and /api/v1/stream call, and one ingestion event per embed run. Question/answer text is never logged — only metadata (e.g. question length).

curl http://localhost:8080/metrics
# {"queries_total":128,"queries_escalated":7,"avg_latency_ms":142.6,"avg_confidence":0.78,"uptime_seconds":3601.2}

Counters are in-memory and thread-safe; they reset on restart. The endpoint is registered on all six servers.

Configuration

Copy .env.example to .env and edit. All variables are also accepted as plain environment variables — no .env file required in CI/CD.

LLM & embedding backends

Generation

Backend	LLM_BACKEND	Extra	Notes
Ollama	ollama	(none)	Default — fully local, no API key, no GPU
OpenAI	openai	[openai]	GPT-4o, GPT-4o-mini, o1, …
vLLM / LM Studio	vllm	[openai]	Local OpenAI-compatible server; set OPENAI_BASE_URL
Groq / Mistral	openai	[openai]	Set OPENAI_BASE_URL to the provider endpoint
Claude	claude	[claude]	Anthropic claude-opus / claude-sonnet …

Switch backend with a single env var. Each module can use a different one via CI_LLM_*, DI_LLM_*, MI_LLM_*. When confidence < ESCALATION_THRESHOLD and ANTHROPIC_API_KEY is set, the answer is escalated to Claude regardless of the primary backend.

Embedding

Backend	EMBED_BACKEND	Extra	Notes
Ollama	ollama	(none)	Default — fully local
SentenceTransformer	st	[st]	CPU-only, fully offline
Claude / Voyage	claude	[claude]	Cloud embeddings via Voyage AI

For non-English content, use a multilingual SentenceTransformer model (paraphrase-multilingual-MiniLM-L12-v2, 50+ languages).

Switching embedding model requires re-indexing from scratch — vector dimensions may change (384 → 768) and ChromaDB rejects mixed-dimension collections. Delete the data dir first:

rm -rf ~/.intelligence_suite/chroma                              # Linux / macOS
Remove-Item -Recurse -Force "$HOME\.intelligence_suite\chroma"   # Windows PowerShell

ChromaDB runs embedded — no server or Docker. Override the path with CHROMA_PERSIST_DIR.

---

Data model — the chunk

Every source file and document is converted into self-contained semantic chunks with a unified schema and a deterministic domain::type::locator ID (so re-indexing is idempotent):

{
  "id":       "code::function::myrepo.auth.jwt.verify_token",
  "domain":   "code",
  "type":     "function",
  "text":     "### verify_token\n\n```python\ndef verify_token(token: str) -> dict:\n    ...\n```",
  "source":   "auth/jwt.py",
  "language": "python",
  "metadata": { "name": "verify_token", "line_start": 42, "line_end": 67,
                "calls": ["jwt.decode"], "imports": ["jwt"] }
}

Domain	Types
code	function, class, interface, config_block, module, file
doc	section, table, paragraph
mentor	practice, onboarding_step, role_guide, faq, glossary

Architecture

The engine — intelligence_core

Every module delegates to these shared components, so a fix here benefits all domains at once:

Component	File	What it does
Chunk schema	chunk.py	Universal unit of knowledge; deterministic domain::type::locator ID
Embedder	embedder.py	Pluggable text→vector (Ollama/ST/Voyage); fails loudly if unreachable
Vector store	store.py	ChromaDB embedded; one collection per domain
Retriever / MultiRetriever	retriever.py	Candidate pool → rerank → optional GraphRAG; multi-collection for cross-domain
Reranker	reranker.py	Cross-encoder re-scoring, sigmoid-normalised, opt-in via RERANK_ENABLED
LLM provider	llm/	Provider-agnostic generation; per-module overrides
Intent routing	intent.py	RAG / SKILL / AGENT classification; falls back to RAG on any failure
Ingestion	ingestion.py, ingest_api.py	On-demand idempotent parse+embed service + opt-in HTTP routes
Export	export.py, export_api.py	Markdown/HTML/PDF renderers + POST /api/v1/export
GraphRAG	graph/	NetworkX dependency graph + context expansion
Evaluation	evaluation/	RAGAS pipeline behind ci-eval

Request lifecycle (a single /api/v1/query)

1. Route — Intent Routing classifies (RAG / SKILL / AGENT).
2. Retrieve — embed the question, pull a candidate pool from ChromaDB.
3. Rerank — cross-encoder re-orders candidates, cut to top_k.
4. Expand (optional) — GraphRAG adds structurally-related code.
5. Generate — the chosen LLM writes an answer grounded in the chunks.
6. Escalate (conditional) — below threshold + Claude key → regenerate via cloud.
7. Respond — answer + source citations + confidence + backend, streamed over SSE.

Design principles

Principle	Implementation
On-premise first	Ollama + ChromaDB by default — no cloud required
Domain-aware chunking	Every chunk carries domain — prevents cross-contamination
Deterministic IDs	domain::type::locator — safe to re-index, dedup-friendly
Fail-safe ingestion	One broken file never crashes the pipeline
Fail-loud embedding	Embedder raises if unreachable — never stores zero-vectors
Non-breaking extras	Tree-sitter, graph, eval, ingest, export are opt-in; absence degrades gracefully

---

Testing

pip install -e ".[dev]"
pytest -m "not slow"       # everything except tests needing a real backend
pytest -m kpi              # only the deterministic retrieval-quality tests

The suite runs offline and deterministically — no Ollama, no network, no optional extra, no disk state required. KPI tests run in CI (they no longer skip): they mount a disk-less, in-memory ChromaDB loaded with versioned synthetic fixtures and assert Hit@1 / Hit@5 / MRR on known chunks. ci-eval (RAGAS) needs a live LLM + populated store, so it stays out of standard CI — see CI.md.

---

Troubleshooting

• CLI scripts not found after install (Windows) — pip installs them in a user Scripts folder that may not be on PATH. Add it, or run modules directly: python -m CodeIntelligence.rag_server.
• Ollama not reachable during embedding — ci-embed/di-embed fail loudly (no silent zero-vectors). Start Ollama (ollama serve && ollama pull nomic-embed-text) or set EMBED_BACKEND=st (offline, no server).
• ChromaDB DuplicateIDError on embed — chunks.jsonl has duplicate IDs, usually because build/lib/ got indexed. rm -rf build/ dist/ ~/.intelligence_suite/chroma and re-run. parse_repo excludes build/, dist/, venv/ automatically.
