CueLight

by sshah03 (individual developer, name not stated) SDK + MCP in Conversational voice agents

sshah03 · sshah03.github.io · who's behind it

CueLight is an open-source Python library and set of open-weight models that estimate, every 20 ms of streaming audio, whether a voice-agent user has finished their turn. It runs locally from audio alone, in English.

Best for A turn-detection component for teams assembling their own voice pipeline (OpenVoiceOS, Pipecat-style stacks), especially on small devices.

Surface listed
The Python package cuelight 0.1.0 (TurnDetector, Endpointer, EndpointPolicy, load) and its three model repositories on Hugging Face, read from the source, the README and the model cards on 15 October 2026. Nothing was installed or run
Interface
TurnDetector.push(chunk) takes 320 float32 samples (20 ms at 16 kHz mono) and returns p(end of turn), with p_speech for the same frame. Endpointer.push(chunk) returns True once when the turn ends
Models
cuelight-nano (0.5M parameters, 1.9 MB, ONNX step file), cuelight-nano-ssm (0.5M, experimental, ONNX step file), cuelight-base (88M, 336 MB, PyTorch only)
Presets
snappy (default, about 1 in 10 pauses interrupted by the author's measure) and careful (about 1 in 20), or a custom EndpointPolicy(threshold, min_silence_s, timeout_s)
Languages
English only. The README says other languages are not planned soon
Runtime
Python 3.10 or later, PyTorch 2.1 or later, numpy, safetensors, huggingface_hub. Weights load from safetensors
Framework integrations
None in the project, which says it depends on no voice framework. OpenVoiceOS maintains a plugin wrapper, whose README says it is not on PyPI yet
Telemetry
None found in the package source (searched 2026-10-15). Weight downloads go through huggingface_hub, whose own settings apply
Project age
One day at the check. One commit, no tags, releases, issues or pull requests
Releases in 90 days

Strengths

  • Apache-2.0 code and weights, with every training dataset and teacher model named in NOTICE
  • Nano is 0.5M parameters and 1.9 MB, with ONNX step files for non-Python runtimes
  • Works from audio alone and updates during speech, not only at pauses
  • Two tuned presets and a custom policy, behind a four-name Python interface
  • Weights load from safetensors, and no telemetry was found in the source

Weaknesses

  • English only, and the author does not plan other languages soon
  • Not on PyPI, no tags, releases, changelog or CI, and one commit at the check
  • Benchmarks are self-reported, and the presets were tuned on half of the benchmark they are scored on
  • Weights download from Hugging Face main branches with no pinned revision
  • An unknown preset name falls back silently to default thresholds

Before you call it notes for agents

  1. Feed 320 float32 samples at 16 kHz mono per push. Resample first, or the call raises an AssertionError
  2. Spell the preset as snappy or careful. Any other name silently uses default thresholds
  3. Call clear() before a new call or session. Pass reset_on_turn_start=False if your pipeline already resets per turn
  4. Pin weights by downloading them to a local folder and passing that path to from_pretrained
  5. Don't use it to identify speakers or clone voices. The training data's conditions forbid it

Terms and privacy, as read

Terms of service none to read

TL;DR Nothing is hosted by the vendor, so there are no terms of service to read. The Apache-2.0 licence stands in and the check scores in full.

Privacy policy none to read

TL;DR Nothing is hosted by the vendor, so there is no privacy policy to read and the check isn't scored.

A reading by a fixed set of rules, each answered with the vendor's own sentence. It isn't legal advice, a rule can miss a clause or misread one, and the document itself is what binds. How it's read and scored.

A library and model weights, not a service. Code on github.com/sshah03, weights on huggingface.co/sshah03, demo on GitHub Pages. No domain of its own.

The LICENSE is Apache-2.0 and NOTICE reads Copyright 2026 sshah03, with third-party model and dataset licences in NOTICE and LICENSES/.

The GitHub account sshah03 was created on 10 July 2012 and gives no name, company or website.

No terms or privacy document governs the library or the demo page. Nothing is hosted beyond static GitHub Pages files, so both fields are left out.

No changelog, tags or GitHub releases. The repository has no SECURITY.md, and github.io serves no security.txt for the project.

The repository was created on 13 October 2026 19:15 UTC and its one commit pushed on 14 October 2026 01:25 UTC.

Checked 2026-10-15 against the vendor's own pages and the domain registry. Provenance is half of Transparency & trust.

Notable

  • The repository's single commit, "CueLight: always-listening turn detector (Nano, Nano-SSM, Base)", is dated 14 October 2026 01:25 UTC, and the three Hugging Face model repositories were created the same minute source
  • Three models. Nano is a 0.5M-parameter causal GRU (1.9 MB), Nano-SSM swaps in a Mamba-3 core (experimental), Base is a causal Whisper small.en encoder (88M parameters, 336 MB) source
  • The README reports Nano at 0.5 ms and Base at 5.0 ms of one Apple M4 Pro core per 20 ms of audio. These are the author's figures, not ours source
  • Benchmarks against Smart Turn v3.2 and LiveKit v1-mini on eot-bench and Smart Turn's test set are self-reported, and the presets were tuned on half of eot-bench source
  • Not on PyPI. Install is pip install git+https://github.com/sshah03/CueLight, package version 0.1.0, with no tags or releases source
  • A browser demo on GitHub Pages runs Nano's ONNX step model in WebAssembly, and its code fetches only model files and onnxruntime-web source
  • Show HN post on 14 October 2026. OpenVoiceOS published a wrapper plugin, ovos-eot-plugin-cuelight, the same day source

Score breakdown methodology v0.4 · October 2026 research run

Assessed on 15 October 2026 from public evidence, against the published checklist. Confidence medium. Performance and Task success are pending until our probes and task suites run, so the total is over the 7 assessed categories, each weight divided by 80.

CategoryWeight this runScorePoints
Reliability 16%20 5.8
Read as local software. Installs with pip from the Git repository, not from PyPI, with Python 3.10 or later and its dependencies declared in pyproject.toml (10 of 20). The repository holds two tests (streaming matches whole-sequence output, chunk size is enforced), but the only GitHub workflow is the Pages deployment, so no public CI runs them (5 of 25). No issues or pull requests exist, and at one day old there is no record to judge either way (12 of 25). Version 0.1.0 in pyproject.toml with no tags or changelog (2 of 15). Below 1.0, and the README calls it a first iteration (0).
Performancenot scored in this run 10%pending pending n/a
Schema & documentation 13%16.2 8.1
Library reading. No OpenAPI applies. The public classes are small, with type hints on most signatures and frozen dataclasses for both policies, though push takes an untyped chunk (15 of 25). No llms.txt on the Pages site, and docs are the README (0). The README says which model suits which device, when to choose each preset, and states the limits (English only, audio only, Base's CPU cost) (16 of 20). The 320-sample frame is enforced by an assert, while an unknown preset name falls back silently to default thresholds rather than raising (8 of 15). Quick-start snippets and two example scripts. Error behaviour is not documented (8 of 15). A version number in pyproject.toml and __version__, with no changelog (3 of 15).
Agent ergonomics 13%16.2 9.9
Library reading. Four public names and one call per frame, with an 11 KB README, so the context cost of learning it is low (22 of 25). Output is one probability and one speech probability per frame, and thresholds, minimum silence, timeout and reset behaviour can all be set (14 of 20). The only error is an assert on chunk size, which python -O strips, and a mistyped preset gives defaults without a warning (6 of 20). push is stateful by design. clear() resets between calls and the detector resets itself at each new turn, and the source shows streaming matches whole-clip output to 1e-4 (10 of 20). One required argument with working defaults. Python only, with ONNX step files and a browser demo but no packaged second-language SDK (9 of 15).
Security & auth 14%17.5 8.8
Local-software reading. No credential and no open port. The code runs in the caller's process, weights load from safetensors rather than pickle, but snapshot_download fetches the main branch of each Hugging Face repository with no pinned revision (20 of 30). It only classifies audio and takes no actions (16 of 20). It returns probabilities, not content from third parties (10). No logging. Per-frame probabilities and a reset counter are visible to the caller (4 of 15). No SECURITY.md, disclosure policy, security.txt or advisories (0 of 20).
Payments & pricing 10%12.5 7.5
No payment protocol (0). Read with the self-hosted rule. Apache-2.0 code and weights with no hosted or paid option (20). No card or account (20). Weights download anonymously, with no signup (20).
Task successnot scored in this run 10%pending pending n/a
Maintenance & community 7%8.8 4.0
Published on 14 October 2026, one day before the check (30). One publication and no tagged releases, given a quarter of the line as for a single release elsewhere (5 of 20). No issues or pull requests yet, so responsiveness cannot be seen (5 of 25). Not on PyPI. The weights are on Hugging Face and the package installs only from Git (3 of 15). Dependencies are current minimums (torch 2.1 or later), with no lockfile, Dependabot or CI (3 of 10). The project is one day old, so these lines reflect the checklist, not a judgement of the maintainer.
Transparency & trusteditorial 67, provenance 40 7%8.8 4.7
Apache-2.0 for code and weights, with a NOTICE that lists each training dataset, teacher model and licence, and the conditions passed on from the data (30). Nothing is hosted. The README says the browser demo keeps audio on the device, which the demo code agrees with, and that weights download from Hugging Face on first use. There is no privacy statement as such (22 of 30). No deprecation policy or dated notices (0 of 20). No telemetry found in the package or demo source. The README does not mention telemetry, and huggingface_hub's own defaults are not discussed (15 of 20).

# Fix list: CueLight

From Anchor Terminal's listing at https://www.anchorterminal.com/tools/cuelight, the October 2026 research run, assessed 15 October 2026. Grade D, 48.8 out of 100.

This is everything the published grade says the listing lacks, the biggest possible gain to the total first. It comes from the reason given for each score, the checklist each category was scored against (https://www.anchorterminal.com/benchmark/#checklist), the provenance checks, the deductions, what we couldn't check and what the review panel asked for. A fix counts at the next check, once it's public.

For a coding agent working on CueLight: work through the items below in the product, its docs and its public pages. Each category gives the reason for its score, with the points each checklist item earned, and the checklist itself, so the gap is the items that earned less than their points. Change the product, not the wording, and keep a note of what you changed and where it's published.

## 1. Reliability, 29 out of 100, up to 14.2 more on the total

Why it scored 29: Read as local software. Installs with pip from the Git repository, not from PyPI, with Python 3.10 or later and its dependencies declared in pyproject.toml (10 of 20). The repository holds two tests (streaming matches whole-sequence output, chunk size is enforced), but the only GitHub workflow is the Pages deployment, so no public CI runs them (5 of 25). No issues or pull requests exist, and at one day old there is no record to judge either way (12 of 25). Version 0.1.0 in pyproject.toml with no tags or changelog (2 of 15). Below 1.0, and the README calls it a first iteration (0).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-reliability):

Hosted APIs, MCP servers, models and platforms.

- 20, a public status page with component history (Statuspage, Instatus, BetterStack or the vendor's own).
- 0 to 30, the incident record for the last 90 days on that page. 30 for a clean record or trivial incidents only, 20 for minor incidents only, 10 for one major outage (an hour or more of a core API down, or errors across the board), 0 for several. 5 when there's no history we could read, and the note says so.
- 15, rate limits documented with numbers.
- 15, documented 429 or overload handling (Retry-After, backoff guidance), and idempotency keys or safe-retry guidance where writes are involved.
- 10, an SLA published for any paid tier.
- 10, the surface agents use is generally available, not beta or preview.

Local packages, SDKs, frameworks and stdio MCP servers.

- 20, installs from an official package with supported runtimes stated.
- 25, a public CI and test suite, passing on the default branch.
- 0 to 25, open crash or regression issues relative to activity (25 for few and handled, 0 for many, old and unanswered).
- 15, semver discipline and breaking changes called out in a changelog.
- 15, version 1.0 or later, or declared stable.

Protocols are read from their reference implementations, the public facilitators or servers, spec stability and test vectors.

## 2. Security & auth, 50 out of 100, up to 8.8 more on the total

Why it scored 50: Local-software reading. No credential and no open port. The code runs in the caller's process, weights load from safetensors rather than pickle, but `snapshot_download` fetches the main branch of each Hugging Face repository with no pinned revision (20 of 30). It only classifies audio and takes no actions (16 of 20). It returns probabilities, not content from third parties (10). No logging. Per-frame probabilities and a reset counter are visible to the caller (4 of 15). No SECURITY.md, disclosure policy, security.txt or advisories (0 of 20).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-security):

- 0 to 30, the credential model. 30 for OAuth 2.1 with scopes, or scoped and revocable keys with rotation. 20 for plain revocable API keys. 10 for one all-powerful key. 10 off when a secret can travel in a URL query string as a documented option.
- 0 to 20, read-only or least-privilege modes, and confirmation or approval for destructive actions.
- 0 to 15, prompt-injection posture where the tool returns untrusted content (documented mitigations or guidance). A tool that returns no untrusted content gets 10.
- 0 to 15, audit logs or per-call visibility for the operator.
- 0 to 20, a security programme. security.txt or a disclosure policy, a bug bounty, SOC 2 or ISO 27001, advisories handled in public.

Models are read for retention, whether API data trains models (and whether that's off by default), zero-retention options and certifications. Frameworks for telemetry defaults, approval hooks, guardrails and sandboxing.

## 3. Schema & documentation, 50 out of 100, up to 8.1 more on the total

Why it scored 50: Library reading. No OpenAPI applies. The public classes are small, with type hints on most signatures and frozen dataclasses for both policies, though `push` takes an untyped chunk (15 of 25). No llms.txt on the Pages site, and docs are the README (0). The README says which model suits which device, when to choose each preset, and states the limits (English only, audio only, Base's CPU cost) (16 of 20). The 320-sample frame is enforced by an assert, while an unknown preset name falls back silently to default thresholds rather than raising (8 of 15). Quick-start snippets and two example scripts. Error behaviour is not documented (8 of 15). A version number in pyproject.toml and `__version__`, with no changelog (3 of 15).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-schema):

APIs and MCP servers.

- 25, a machine-readable contract (a public OpenAPI file or similar; for MCP, typed JSON Schema inputs on every tool).
- 10, llms.txt or Markdown docs served for agents.
- 0 to 20, descriptions that say what a tool is for, when to use it and when not to, read from the tool definitions in the source or the API reference.
- 0 to 15, typed inputs with enums, constraints and required fields, and no free-form JSON blobs.
- 0 to 15, examples and documented error responses.
- 15, versioning and a public changelog.

Models are read from the API reference, the OpenAPI file, llms.txt, the structured-output and tool-use docs and the model cards. Frameworks from docs a model can follow, typed interfaces, examples and the API reference.

## 4. Agent ergonomics, 61 out of 100, up to 6.3 more on the total

Why it scored 61: Library reading. Four public names and one call per frame, with an 11 KB README, so the context cost of learning it is low (22 of 25). Output is one probability and one speech probability per frame, and thresholds, minimum silence, timeout and reset behaviour can all be set (14 of 20). The only error is an assert on chunk size, which `python -O` strips, and a mistyped preset gives defaults without a warning (6 of 20). `push` is stateful by design. `clear()` resets between calls and the detector resets itself at each new turn, and the source shows streaming matches whole-clip output to 1e-4 (10 of 20). One required argument with working defaults. Python only, with ONNX step files and a browser demo but no packaged second-language SDK (9 of 15).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-ergonomics):

- 0 to 25, context cost. For MCP, the number and size of the tool definitions (25 for ten or fewer compact tools, 15 for 11 to 30, 5 for more than 30, plus up to 10 back for toolsets, dynamic loading or read-only subsets). For APIs, whether responses can be sized (field selection, limits, summaries).
- 20, pagination, filtering and output-size controls.
- 20, actionable, documented error responses, codes and messages an agent can recover from.
- 20, idempotency or safe retries, and for MCP the `readOnlyHint` and `destructiveHint` annotations.
- 15, sensible defaults, few required parameters, and official SDKs in at least two languages.

Models are read for tool use, structured output, prompt caching, context length, batch and SDKs. Frameworks for how much code and how many defaults a tool-calling agent with MCP needs.

## 5. Payments & pricing, 60 out of 100, up to 5 more on the total

Why it scored 60: No payment protocol (0). Read with the self-hosted rule. Apache-2.0 code and weights with no hosted or paid option (20). No card or account (20). Weights download anonymously, with no signup (20).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-payments):

The published rubric, also on the [x402 page](https://www.anchorterminal.com/x402/).

- 40, a machine payment protocol (x402, MPP or L402) on the tool's own endpoints. 10 to 30 when it covers only some endpoints or only goes through a third party, and the note says which.
- 20, per-call or per-unit pricing published without a login. 10 for public plan-only pricing, 0 for "contact sales" or prices behind a login.
- 20, a free tier or trial that doesn't need a card.
- 20, autonomous onboarding, meaning an agent can get access without a person signing up in a browser (keyless use, x402, a programmatic key API).

Payment platforms and agent wallets rarely charge for their own API over a machine protocol, so the first line has steps for them, and the highest one that applies counts. 40 when x402, MPP or L402 runs on all their own endpoints, 30 when it runs on part of their own API, 25 when their merchants can accept one, 20 for running a facilitator, 15 for paying as a buyer, and 0 when the only protocol is their own. Merchant acceptance sits above a facilitator because the platform's own customers can charge agents through it, while a facilitator settles for sellers who wire up the protocol themselves. The counter-argument (a facilitator does more for the protocol as a whole) has a point. Each note says which step applied.

Open-source software you run yourself is scored on its hosted or paid option if it has one. A free, self-hosted package with nothing to buy gets 20, 20 and 20 for the last three lines, and 0 to 40 for the first only if it ships a payment protocol.

## 6. Maintenance & community, 46 out of 100, up to 4.7 more on the total

Why it scored 46: Published on 14 October 2026, one day before the check (30). One publication and no tagged releases, given a quarter of the line as for a single release elsewhere (5 of 20). No issues or pull requests yet, so responsiveness cannot be seen (5 of 25). Not on PyPI. The weights are on Hugging Face and the package installs only from Git (3 of 15). Dependencies are current minimums (torch 2.1 or later), with no lockfile, Dependabot or CI (3 of 10). The project is one day old, so these lines reflect the checklist, not a judgement of the maintainer.

The checklist (https://www.anchorterminal.com/benchmark/#checklist-maintenance):

- 0 to 30, time since the last release, or the last published model or API change for a closed service. 30 within 30 days, 20 within 90, 10 within 180, 0 older.
- 20, at least three releases or dated changelog entries in the last 90 days.
- 0 to 25, responsiveness. Issues and pull requests answered on GitHub (the open issues and how recent the replies are). For closed services, a public changelog and a support or community channel that answers, 0 to 15.
- 15, presence in the official MCP registry under a verified namespace (MCP servers), or current official SDKs (APIs and models).
- 10, package health, current dependencies and CI.

Models are read for deprecation notice periods and model churn rather than release counts.

## 7. Transparency & trust, 54 out of 100, up to 4 more on the total

Made of editorial 67, provenance 40.

Why it scored 54: Apache-2.0 for code and weights, with a NOTICE that lists each training dataset, teacher model and licence, and the conditions passed on from the data (30). Nothing is hosted. The README says the browser demo keeps audio on the device, which the demo code agrees with, and that weights download from Hugging Face on first use. There is no privacy statement as such (22 of 30). No deprecation policy or dated notices (0 of 20). No telemetry found in the package or demo source. The README does not mention telemetry, and huggingface_hub's own defaults are not discussed (15 of 20).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-transparency):

- 0 to 30, source availability and licence clarity. 30 for open source under an OSI licence, 15 for closed with clear terms, 0 for unclear terms.
- 0 to 30, data handling and retention statements that agree with each other (privacy policy, DPA, retention periods, subprocessors).
- 0 to 20, a deprecation policy or notices with dates.
- 0 to 20, telemetry disclosed with an opt-out (local software), or subprocessors and data locations disclosed (hosted).

The other half of Transparency and trust is the provenance score, computed from checked facts (below). The category score is the mean of the two.

Provenance checks not met in full (half of this category, computed from checked facts):

- Domain age: sshah03.github.io, no registry record we could read (0 of 15)
- Status page: not found (0 of 10)
- Changelog: not found (0 of 10)
- security.txt: not found (0 of 10)

## What we couldn't check

What we couldn't read counted as absent. Publishing it on a page a plain HTTP fetch can read (not only in a browser) lets the next check count it.

- Judgement call on category. Listed in voice agents under `voice.pipeline`, as a component of the speech-to-text, model and text-to-speech chain, because no category covers turn detection on its own. It runs no conversation, so `voice.agent` is left out. `inference.open-weights` is added because the weights are published.
- The lead was right. Initial commit and the Nano, Nano-SSM and Base weights on 14 October 2026 UTC (13 October in the author's time zone). `firstReleased` is 2026-10-14. The project was one day old at the check.
- Graded on the Python library interface, which is what an agent-building pipeline would call. There is no hosted API or local server.
- We did not install or run the package or the demo. Accuracy and CPU figures are the author's, from the README.
- The author's eot-bench results use presets tuned on half of eot-bench, and eot-bench data was used to choose between models. The README discloses both. No deduction, since the claims are qualified.
- The OpenVoiceOS plugin README gives `pip install ovos-eot-plugin-cuelight`, but PyPI had no such project on 15 October 2026.

## Weaknesses

- English only, and the author does not plan other languages soon
- Not on PyPI, no tags, releases, changelog or CI, and one commit at the check
- Benchmarks are self-reported, and the presets were tuned on half of the benchmark they are scored on
- Weights download from Hugging Face main branches with no pinned revision
- An unknown preset name falls back silently to default thresholds

## What costs an agent a turn today

The notes we give agents before they call it. Each one is a workaround an agent shouldn't need.

- Feed 320 float32 samples at 16 kHz mono per `push`. Resample first, or the call raises an AssertionError
- Spell the preset as `snappy` or `careful`. Any other name silently uses default thresholds
- Call `clear()` before a new call or session. Pass `reset_on_turn_start=False` if your pipeline already resets per turn
- Pin weights by downloading them to a local folder and passing that path to `from_pretrained`
- Don't use it to identify speakers or clone voices. The training data's conditions forbid it

## When it's done

Send what changed and where it's published as a dispute (https://www.anchorterminal.com/builders/#disputes, or `POST https://www.anchorterminal.com/api/v1/contact` with `"kind": "dispute"`). Disputes are answered in public, and the listing is checked again by the same checklist. Paying for an audit or a listing claim changes nothing here.

What we couldn't check

  • Judgement call on category. Listed in voice agents under voice.pipeline, as a component of the speech-to-text, model and text-to-speech chain, because no category covers turn detection on its own. It runs no conversation, so voice.agent is left out. inference.open-weights is added because the weights are published.
  • The lead was right. Initial commit and the Nano, Nano-SSM and Base weights on 14 October 2026 UTC (13 October in the author's time zone). firstReleased is 2026-10-14. The project was one day old at the check.
  • Graded on the Python library interface, which is what an agent-building pipeline would call. There is no hosted API or local server.
  • We did not install or run the package or the demo. Accuracy and CPU figures are the author's, from the README.
  • The author's eot-bench results use presets tuned on half of eot-bench, and eot-bench data was used to choose between models. The README discloses both. No deduction, since the claims are qualified.
  • The OpenVoiceOS plugin README gives pip install ovos-eot-plugin-cuelight, but PyPI had no such project on 15 October 2026.

Probe metrics

Not measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. The pollers record uptime for hosted endpoints as they run, and that doesn't change the score either.

Pricing & changes

Free Free · OSS Free under Apache-2.0 for code and weights, with no hosted or paid option. The owner pays only for the CPU it runs on. Conditions carried over from the training data ask that it not be used to identify speakers or clone voices.

For the vendor

Is this your product? Link to this page from your own site or README, then tell us where. It shows people and agents that the listing is yours and that you know it's here. It never changes a grade, rank or review.

    It counts on a page on sshah03.github.io or one of its subdomains, or the README of github.com/sshah03/CueLight.

  2. Tell us where it is

    We read it once now and again every week. If the link is missing two weeks in a row the listing says so, and a later check puts it back.

Agents send the same to POST /api/v1/verify as {"slug": "cuelight", "url": "…"}, or call the verify_listing tool at /mcp. Ten checks an hour from one address. What we check. To announce the listing, get sharing assets for social media.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
