Respect the global `~/.claude/CLAUDE.md` instructions strictly. +## What this project is + +`canpy` is the CLDK Python static analyzer. It emits the canonical CLDK +`analysis.json` — a **symbol table** plus a **call graph** — and can project that same +analysis into a **Neo4j** property graph. It mirrors its +[TypeScript](https://github.com/codellm-devkit/codeanalyzer-typescript) (`cants`) and +[Java](https://github.com/codellm-devkit/codeanalyzer-java) sibling analyzers, so +output-shape parity with them is a first-class concern. + +The engine is **[Jedi](https://jedi.readthedocs.io/)** (plus stdlib `ast`/`tokenize`) +for the symbol table, with a two-level call graph: level 1 is Jedi lexical resolution +(always on); level 2 (`--analysis-level 2`) adds the embedded +[PyCG](https://github.com/vitsalis/PyCG) flow analyzer, which recovers edges the lexical +pass misses. Merged edges keep a `provenance` tag (`jedi` / `pycg`); the schema also +reserves `joern`. (Heads-up: the README/`pyproject` still mention CodeQL, but there is +**no CodeQL provider** in the source — PyCG is the level-2 backend.) + +## Architecture — follow the pipeline + +The whole analyzer is one orchestrator: the **`Codeanalyzer`** context-manager class in +`codeanalyzer/core.py`, entered via **`analyze() -> PyApplication`**. Read it first; +everything else is a stage it calls, in order: + +1. **cache load** — `_load_pyapplication_from_cache()` reuses `analysis_cache.json` + unless `--eager`. +2. **symbol table** (`codeanalyzer/syntactic_analysis`) — `_build_symbol_table()` drives + `SymbolTableBuilder.build_pymodule_from_file()` per file (serial or Ray), reusing + unchanged files via mtime/size + SHA256 `content_hash`. +3. **call graph** (`codeanalyzer/semantic_analysis`) — `resolve_unresolved_constructors`, + then `jedi_call_graph_edges` (provenance `jedi`); at `-a 2`, `_get_pycg_call_graph` + adds PyCG edges (provenance `pycg`), coalesced by `merge_edges`. +4. **externals** — `filter_external_edges` drops lib→lib edges; `_compute_external_symbols` + builds the `PyExternalSymbol` map for undeclared call targets (ghost nodes). +5. **assemble + cache** — `PyApplication.builder()…build()`, then `_save_analysis_cache()`. + +Output is dispatched by the CLI (`codeanalyzer/__main__.py`, not `analyze()`): stdout +JSON, `analysis.json`/`analysis.msgpack`, or a Neo4j `emit_neo4j`/`emit_schema`. + +The shape of everything is the **Pydantic schema** in `codeanalyzer/schema/py_schema.py` +(`PyApplication` is the top type). The Neo4j schema is a *separate*, versioned contract in +`codeanalyzer/neo4j/catalog.py` — treat it as a contract enforced by conformance tests. + +## Directory map + +| Path | Responsibility | +|------|----------------| +| `codeanalyzer/__main__.py` | Entry point + Typer CLI, flag parsing, output dispatch | +| `codeanalyzer/core.py` | `Codeanalyzer.analyze()` orchestrator — the spine | +| `codeanalyzer/options` | `AnalysisOptions` + `OutputFormat`/`EmitTarget`/`ShardStrategy` enums | +| `codeanalyzer/syntactic_analysis` | Symbol table (Jedi + `ast`/`tokenize` traversal) | +| `codeanalyzer/semantic_analysis` | Call-graph helpers (jedi edges, merge/filter); `pycg/` = level-2 provider + coupling-aware sharding | +| `codeanalyzer/schema` | `PyApplication` Pydantic models (the output contract) | +| `codeanalyzer/neo4j` | Graph projection: `catalog.py` (schema + `SCHEMA_VERSION`), `cypher.py` (snapshot), `bolt.py` (incremental push), `emit.py` (facade) | +| `codeanalyzer/utils` | logging, progress bar | +| `test` | Pytest suite + `test/fixtures` (flask, requests) | + +## Commands + +Tooling is **uv** + **hatchling** + **pytest** (no Makefile). + +- `uv sync --all-groups` — install/sync deps. +- `uv run canpy --input /path/to/project` — run the analyzer from source. +- `uv run pytest` — run tests.

Default to guiding, not doing. +- **Do** move me fast: explain the relevant stage, point at prior art (e.g. the existing + Jedi edge builder in `semantic_analysis` as the template for a new provider), sketch + signatures/types, outline an approach, and answer questions about the codebase. +- **Review on request:** when I share a diff or push, critique it — correctness, + **parity with the TypeScript/Java backends**, schema conformance, missing tests, edge + cases — and suggest concrete improvements. +- Scaffolding like tests or boilerplate is fine **when I ask**; otherwise leave the + keyboard to me. +- If you think I'm about to go wrong, say so briefly and let me decide — don't pre-empt + by implementing the fix. + +## Rules + +1. **Think before coding.** State assumptions explicitly; ask rather than guess. Push + back when a simpler approach exists. Stop when confused. +2. **Simplicity first.** Guide me toward the minimum idiomatic code that solves the + problem. Nothing speculative; no abstractions for single-use code. +3. **Issue → branch → work → PR.** Every change starts as an issue, on a branch named + `feat/issue-XXX`, `fix/issue-XXX`, `chore/issue-XXX`, and lands via a PR. +4. **Guard the contract.** Changes to `codeanalyzer/schema` or Neo4j output must keep + parity with the sibling analyzers and pass the schema conformance test + (`test/test_neo4j_schema.py`, which also asserts the checked-in `schema.neo4j.json` is + current). + +## Goal-driven execution, as a teaching loop + +Success is measured by the sole fact that **I understand it**.
