What is SpotifyScraper CLAUDE.md?

Project instructions for AI coding agents and developers working on SpotifyScraper, a Python library that extracts public Spotify data without the official API. They describe the project’s structure, rules, workflow, and commands.

Use them when adding features, checking design decisions, running project commands, or understanding how Spotify data is extracted and modeled.

They give contributors a shared reference for changing the code without breaking its architecture or compatibility requirements.

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	$0.00862	$0.00862
Opus 5.5	$0.00345	$0.00345
Sonnet 5.5	$0.00172	$0.00172

Security

Grade A, and why

SpotifyScraper CLAUDE.md 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.

Guidance for AI coding agents (and humans) working on SpotifyScraper.

What this project is

A Python library that extracts public Spotify data (tracks, albums, artists, playlists, shows, episodes) without the official API. v3 is a clean-room rewrite; the stable v2 line lives on the v2.x branch.

Architecture rules (do not violate)

Sans-io core. All Spotify intelligence — URL parsing, token extraction, request building, payload→model parsing — lives in pure, sync-agnostic functions. Only the thin client facades in _sync/ and _async/ know about I/O.
One runtime dependency. Core depends on httpx only. New functionality that needs another package goes behind an optional extra (media, browser) with a lazy import and a helpful ImportError.
Two-tier extraction ladder. Tier 1: anonymous bearer token (bootstrapped from any embed page's __NEXT_DATA__) → Spotify pathfinder GraphQL. Tier 2 (fallback): parse the entity's own embed page. Tier-1-only model fields are | None. GraphQL persisted-query hashes live ONLY in api/pathfinder.py.
Typed throughout. Frozen slotted dataclasses for models, to_dict() JSON-safe; mypy --strict must pass; exceptions come from the errors.py hierarchy — never return error strings or error dicts.
Hermetic tests by default. Network tests are @pytest.mark.live and excluded by default. Never commit fixtures containing live accessToken, clientId, or cookie values — scrub them (see scripts/capture_fixtures.py once it exists).

Workflow

Spec-first. Every non-trivial change goes through OpenSpec: propose (/opsx:propose) → apply (/opsx:apply) → archive (/opsx:archive). Specs live in openspec/.
Conventional commits are enforced by a commit-msg hook (template: .gitmessage).
One OpenSpec change = one PR into v3 (until v3 merges to master).

Commands

Command	Purpose
`uv sync`	Install/refresh the dev environment
`make lint` / `make format`	ruff check / autofix + format
`make type`	mypy strict on `src/`
`make test`	hermetic test suite
`make cov`	tests with coverage (85% floor)
`make live`	live Spotify smoke tests (network)
`uv build`	build wheel + sdist

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
