Sculptor vs Warp (Warp Agent CLI and the Oz Agent API)

Sculptor 45

Harness reading. A README, specs and agent docs in the repository; no API reference (45).

Warp (Warp Agent CLI and the Oz Agent API) 89

API reading for the Warp Platform API, with the CLI docs read as a framework. docs.warp.dev/openapi.json is OpenAPI 3.0.0 with 293 component schemas and bearer authentication (25). llms.txt with per-section Markdown bundles, including one for the Warp Agent CLI and one for the Automation Platform (10). The run request schema says when each field applies (prompt unless a skill is given, on_behalf_of only for agent keys on team runs), and the CLI permissions page states each default and when auto-approve bypasses the denylist (15). Run modes, states and permission values are enumerated, and request bodies are typed objects (13). Curl and SDK examples throughout, and an error catalogue of RFC 7807 bodies with a machine-readable code, retryable flag and trace ID per error (14). The API sits under /api/v1 with info version 1.0.0, and the weekly changelog has an Oz updates section, but there is no API-only changelog (12). 25 + 10 + 15 + 13 + 14 + 12 = 89. Warp's terms bar any robot, scraper or other automated means to access its Services, so this run pauses its hosts and the readings from warp.dev pages are per the 18 October check, not re-read on 4 November.

Sculptor 60

Free self-hosted software with nothing to buy, so 0 for a protocol and 20 each for public pricing, a free tier and onboarding with no sign-up, 60.

Warp (Warp Agent CLI and the Oz Agent API) 20

Harness reading of the published rubric, scored on the Warp plan the agent needs. No payment protocol (0). Plan prices are public, and Warp-provided inference is billed at public API rates on paid plans, but the agent-hour platform rate and compute rate for cloud runs were not on the pricing page (10). Free is $0 and includes Warp Agent CLI access, but no bundled Warp inference, so the agent runs only with purchased usage or your own provider key. Whether sign-up asks for a card was not tested (10). A person signs in through a browser or device code, and API keys are created by hand in the Oz web app or the Warp app (0). 0 + 10 + 10 + 0 = 20. Warp's terms bar any robot, scraper or other automated means to access its Services, so this run pauses its hosts and the readings from warp.dev pages are per the 18 October check, not re-read on 4 November.

Sculptor 50

Harness reading. Workspaces as isolated copies, review and merge back, and built-in skills (50).

Warp (Warp Agent CLI and the Oz Agent API) 66

Harness reading, adapted to a harness driven by a pipeline. MCP servers are attached per run with --mcp or the mcp_servers config, and profiles gate MCP calls, but no per-tool disabling or deferred tool loading was found (12). The API lists runs with limit, cursor, sort_by, state, task_status and name, and returns a normalised conversation and a timeline per run. The warp CLI has no print mode or JSON output and the Oz CLI's run output is described only as printed tool calls (12). RFC 7807 errors with codes such as insufficient_credits and budget_exceeded, a retryable flag, and since 7 October 2026 unattended CLI runs end as blocked instead of hanging when the agent asks for input. No CLI exit codes are documented (16). Follow-ups, interrupts and cancels by run or conversation ID, conversation_id to continue a run, and warp --resume. No idempotency key on run creation (14). Python and TypeScript SDKs with retries and timeouts, but a cloud run needs an environment ID and a Warp account with usage, and the warp CLI itself can't be driven headless (12). 12 + 12 + 16 + 14 + 12 = 66. Warp's terms bar any robot, scraper or other automated means to access its Services, so this run pauses its hosts and the readings from warp.dev pages are per the 18 October check, not re-read on 4 November.

Sculptor 57

MIT (30). Consent-based telemetry documented in the repository (18 of 30). The README warns of drastic changes during the research preview, with no deprecation policy (5). Opt-in telemetry (20). 30 + 18 + 5 + 20 = 73.

Warp (Warp Agent CLI and the Oz Agent API) 69

The client, including the warp and oz binaries, is AGPL-3.0, an OSI licence, with the UI crates under MIT. The built-in agent harness, the server and Oz orchestration are proprietary, so the part that runs the agent loop is closed. Judgement call (20). The privacy page says Business and Enterprise are covered by zero data retention, the security overview says ZDR applies across all plans and elsewhere mentions it for Enterprise teams, and the legal security page says it is available on the Enterprise plan. The privacy notice gives criteria rather than retention periods. A subprocessor list and a DPA are linked (15). The Oz CLI carries a legacy notice with a promise of guidance before any support change, and the changelog dates renames such as warp-tui to warp, but there is no written deprecation policy or notice period (8). An exhaustive telemetry event table, Rudderstack and Sentry named, and an opt-out in the app's privacy settings. The CLI pages don't describe what the CLI sends or how to switch it off (14). 20 + 15 + 8 + 14 = 57. Warp's terms bar any robot, scraper or other automated means to access its Services, so this run pauses its hosts and the readings from warp.dev pages are per the 18 October check, not re-read on 4 November.

Sculptor 43

Local software. Desktop downloads for Mac (Apple Silicon), Linux and Linux ARM64 (20). checks.yml and a PR gate run on the repository; pass state not read (15). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). sculptor-v tags up to v0.49.0, no changelog file (8). 0.x and labelled a research preview (0). 20 + 15 + 0 + 8 + 0 = 43.

Warp (Warp Agent CLI and the Oz Agent API) 52

Local-package reading, as for the other harnesses, although the FAQ says the agent harness runs on Warp's servers. An install script for macOS and Linux and a PowerShell one for Windows, with supported systems stated (macOS, Linux x64 and Arm64, Windows x64 and Arm64), and a warp-agent-cli cask in Homebrew core that carries a SHA-256. The script itself checks no checksum (18). The repository's Warp CI workflow runs cargo nextest, doc tests, clippy and release-compilation checks on every pull request to master. The repository has 21 workflow files on 4 November. Whether CI passes on the default branch could not be read (15). Issue and pull request counts from the 18 October check came through shields.io badges, a third-party copy of GitHub data this run bars, and are struck. The clone shows 613 commits to master from 6 August. How many open issues are crashes or regressions, and how fast they get replies, could not be read. The weekly changelog records crash fixes in most releases, such as two crash fixes on 7 October 2026 (10). Weekly dated releases with versions such as v0.2026.10.14.08.27 and no breaking-change heading. The binary rename from warp-tui to warp on 23 July 2026 sat under Improvements (4). Version 0.x with date-based numbers. A stable channel is named and the CLI pages carry no beta label (5). Not scored on this reading. Per the 18 October check, not re-read on 4 November, status.warp.dev has components for the agent harness and cloud execution, and logged scheduled cloud agents unavailable for about 2.5 hours on 16 October and session sharing degraded for about 4.75 hours on 30 September 2026. The docs say Warp has no formal SLA. 18 + 15 + 10 + 4 + 5 = 52. Warp's terms bar any robot, scraper or other automated means to access its Services, so this run pauses its hosts and the readings from warp.dev pages are per the 18 October check, not re-read on 4 November.

Sculptor 75

Commits on 6 November 2026 and frequent tagged versions (30). More than three releases in 90 days (20). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent; the README says Imbue can't take many outside contributions yet (0). Current official downloads (15). CI on pull requests (10). 30 + 20 + 0 + 15 + 10 = 75.

Warp (Warp Agent CLI and the Oz Agent API) 84

Every dated source of the vendor's own looked for. The weekly changelog (per the 18 October check, not re-read on 4 November) dated release 2026.10.15 (v0.2026.10.14.08.27), 20 days before the check (30). Homebrew's warp-agent-cli cask moved to 0.2026.10.21.08.25.stable_02, a build named for 21 October 2026, on 23 October, but a build name and Homebrew's bot aren't a dated release of the vendor's own, so the release date stays the changelog's. The repository's own release tags and stable branches stop at June 2026. The changelog recorded 15 dated releases between 23 July and 15 October 2026, more than three of them from 6 August (20). Issues and pull requests are public on GitHub. The 18 October counts came through shields.io badges and are struck. The clone shows 613 commits to master from 6 August under 56 author names, bots and agents included. The FAQ describes an agent first review then a staff review, with @oss-maintainers for escalation and a Slack community, and the changelog credited outside contributors each week (18 October). Maintainer reply times are unread (12). Official Python and TypeScript SDKs, released 6 October 2026 as 1.0.0 and 2.0.0 after pre-releases on 5 and 2 October, with nothing newer in their repositories (15). CI on every pull request and a checksummed Homebrew cask, but the install script verifies nothing (7). 30 + 20 + 12 + 15 + 7 = 84.
