qcoder 0.5.0a3

Quantum circuit analysis and structured feature extraction tools.

qCoder

qcoder is a local, deterministic quantum circuit evidence CLI.

Free qcoder commands run offline and do not call hosted services, upload telemetry, or run QPU/simulator jobs.

Public CLI surface

• qcoder analyze
• qcoder batch
• qcoder context
• qcoder review
• qcoder pro (Pro bootstrap and client contract; non-confidential local plumbing only)

Pro Preview boundaries

Public qcoder ships Free local commands plus a Pro bootstrap/client contract. It is not the sellable hosted Pro product.

For a public, pilot-safe walkthrough, see the Pro Preview pilot walkthrough. The current public PyPI alpha client surface for Pro Preview is qcoder==0.5.0a2. It is not Pro V0.0 and not a sellable launched Pro product.

• Free commands (analyze, batch, context, review) are Apache-2.0, local-first/offline, and useful without Pro. They do not upload data, call a qCoder hosted service, or run QPU/simulator jobs.
• qcoder pro bootstrap (signup, login, install, status, validate) stores local token/config only. It does not upload circuits, run confidential analysis, or generate Pro cards locally.
• qcoder pro workflow --dry-run-manifest writes a local JSON contract (qcoder.pro_preview.workflow_manifest.v0) and performs no network calls. This is the default path for most users.
• qcoder pro workflow --submit posts a sanitized manifest only to an explicitly configured --service-url (or QCODER_PRO_API_URL). Use it only when QRS has given you a service URL and token. The default https://qcoder.ai/preview URL is not accepted for submit.
• There is no generally available production hosted Pro service, account/token issuance, artifact/source upload, telemetry/training ingest, confidential local analyzer/cards, QPU/provider execution, or launched Pro V0.0 behavior in this public-main surface.
• No confidential Pro analysis or cards are bundled in this package. Token-gating is access control only, not a secrecy boundary.

Quick start

Install:

pip install qcoder

Analyze a circuit:

qcoder analyze path/to/circuit.qasm --json

Create local context and review artifacts:

qcoder context path/to/circuit.qasm --out-json preflight.context.json --out-md preflight.context.md
qcoder review --counts-json counts.json --format qiskit_counts --preflight-json preflight.context.json --out-json execution.review.json --out-md execution.review.md

Pro Preview bootstrap (local contract rehearsal):

qcoder pro --help
qcoder pro signup
qcoder pro install --token <token-if-provided>
qcoder pro status
qcoder pro validate
qcoder pro workflow --qasm path/to/circuit.qasm --dry-run-manifest pro.workflow.manifest.json

Use --dry-run-manifest unless QRS has given you a non-default service URL and token for contract rehearsal. Manifest-only submit (no artifact upload) is opt-in:

qcoder pro workflow --qasm path/to/circuit.qasm --submit --service-url <url-qrs-provided>

Support-safe checklist for Pro Preview pilots

Safe to share with QRS support:

• qcoder --version
• command name
• HTTP status or CLI error code
• job_id, if produced
• redacted output
• manifest schema/version

Do not share:

• bearer tokens
• secrets
• source code
• repository archives
• notebooks
• private prompts or chat transcripts
• raw QASM/source artifacts through unsupported paths

Architecture notes: docs/architecture.md.
