qcoder 0.5.0a5

Quantum circuit analysis and structured feature extraction tools.

qCoder

qcoder is a local, deterministic quantum circuit evidence CLI.

The current public local path is qCoder OSS. OSS commands run locally 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 explorer (Explorer Beta account-backed status/demo/evidence checks)
• qcoder student (temporary compatibility alias for Explorer Beta)
• qcoder pro (archived pilot/bootstrap client contract; non-confidential local plumbing only, not a current public product path)

Current product boundaries

Public qcoder ships OSS local commands plus Explorer Beta compatibility commands. Pro is not launched and is not a current public product path.

• OSS commands (analyze, batch, context, review) are Apache-2.0, local-first/offline, and useful without an account or token. They do not upload data, call a qCoder hosted service, or run QPU/simulator jobs.
• Explorer Beta commands (qcoder explorer status, qcoder explorer demo, qcoder explorer evidence) are account-backed checks for Explorer Beta status, built-in guided evidence samples, and derived-context guided evidence for user-owned OpenQASM 2 artifacts. The older qcoder student ... commands remain available as beta compatibility aliases.
• Explorer Beta custom evidence uses locally derived qCoder context/features. The CLI may read QASM locally, but the hosted request must not include raw QASM, raw source text, local paths, operation lists, raw counts, notebooks, prompts, tokens, auth headers, or cookies.
• Explorer Beta custom evidence is stateless in this v0 slice; it does not create persistent Explorer history.
• qcoder pro bootstrap/workflow commands are archived pilot/client-contract surfaces. They are not a Pro purchase path, not a current public signup path, and not generally available hosted Pro.
• There is no generally available production hosted Pro service, Pro 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

Explorer Beta compatibility checks and archived Pro bootstrap:

qcoder explorer status
qcoder explorer demo
qcoder explorer evidence
qcoder explorer evidence --qasm path/to/circuit.qasm
qcoder explorer evidence --context-json preflight.context.json
qcoder pro --help

Support-safe checklist

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.
