Clawboo vs Sculptor

Clawboo 83

Harness reading of the framework line, as for Paperclip. The REST API's 199 routes are documented per resource with parameters, bodies and responses, and the MCP tools reference gives typed arguments for every tool on the four servers, but no OpenAPI file was found (17). llms.txt, llms-full.txt and a Markdown copy of every page at .md on docs.claw.boo (10). The docs say what each part does and does not cover, with known issues, production defaults and a limits page that names the code line behind each number (17). Tool arguments are typed with required and optional fields and documented caps, such as 24 live subtasks per parent and limits lowered to 1,000, with free-text task bodies (12). curl examples on each API page, an events and errors reference, and the exact error strings each MCP tool returns (14). A dated changelog for every release with an Unreleased section, though API paths carry no version and every MCP server reports 0.1.0 (13).

Sculptor 45

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

Clawboo 75

Harness reading, scored on what an agent or pipeline driving it has to supply. Four MCP servers keep tool lists small (12 Tasks tools, 4 Memory tools, 2 or 3 TeamChat tools, and Tools with four demonstration builtins plus granted connectors), Clawboo Native gets a read-only Tasks subset, and Tools results over 16 KiB are trimmed with a handle to read the rest (22). Circuit breakers stop task-runner runs after more than 30 tool calls or 200,000 tokens a minute, and team chat caps hand-offs at 8 a turn and three levels. Budgets warn only unless set to a hard cap, and a hard cap stops most runs only between runs (14). REST errors use one {error} shape, refused MCP calls return denied: with a reason prefix, and 429s carry Retry-After (16). claim_task and assign_task are atomic, illegal status changes are refused by name, the board survives restarts and routines resume after failure. No MCP tool annotations are documented (14). One npx command and a provider key or a local Ollama, but Claude Code teammates need a global install with the Agent SDK, and there is no client SDK (9).

Sculptor 50

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

Clawboo 51

0.5.0 was published to npm on 21 October 2026 (30). Two releases in the 90 days to 1 November 2026, 0.4.0 on 28 September and 0.5.0, below the three the line asks for (0). github.com was unreachable, so replies to issues, pull requests and Discussions are unchecked. The CI file cites issue #140 as fixed (3). One public npm package, current, with no entry in the official MCP registry for its four servers (10). CI, CodeQL, weekly Dependabot and SLSA provenance on 0.4.0 and 0.5.0, with @composio/client pinned to an alpha (8).

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.

Clawboo 70

Harness reading of the framework checklist, as for the other harnesses. 30 for what leaves the machine by default, 20 for approvals and sandboxing, 15 for prompt-injection posture, 15 for audit and 20 for the security programme. The docs say Clawboo sends no telemetry and list the GitHub catalogue fetch, the npm version check, OpenRouter's public model list, Google Fonts and the GitHub star count, of which only the catalogue address can be changed (27). Clawboo Native shell commands are off by default and asked one at a time, and connector grants are per agent with approval on writes. Claude Code, Codex and Hermes run with their prompts and sandboxes off and no setting to change it, they can read Clawboo's database and key vault, and with no access token by default any local program can answer approval cards (8). Images in agent text don't load on their own, peer posts are marked as evidence, and a run that has read private data and untrusted content asks before any outbound connector call (11). An audit log of budget, breaker, approval, verification, tool-call and install events, with secrets masked (13). SECURITY.md with private reporting, CodeQL, Dependabot and npm provenance. No security.txt or bug bounty, OSV lists no advisory for clawboo, and the proxy advisory is on the docs with a workaround while its fix is unreleased (11).

Sculptor 57

Harness reading. Product analytics, error reporting and session recording default to off in the user config, and the app asks for a telemetry level and privacy consent at first run; PostHog runs on the front end only for now (25 of 30). Each workspace is an isolated copy of the code (14 of 20). No prompt-injection guidance (5). No audit log (5). SECURITY.md (8). 25 + 14 + 5 + 5 + 8 = 57.

Clawboo 52

Read as local software. The official npm package clawboo states Node.js 22.12 or newer, and the README says macOS, Linux and Windows are supported (20). ci.yml runs lint, typecheck, Vitest and a real-concurrency suite on Linux and platform suites on Windows and macOS, and publish.yml reruns build, lint, typecheck, tests and a clean-install boot before it publishes. 0.5.0 carries provenance from that workflow on main, so its checks passed at that commit, but run results on main couldn't be read (15). github.com was unreachable, so open crash and regression issues are unchecked. A known-issues page lists 25 entries with a status each, three of them fixed on main (5). Changesets write a changelog entry per release, and removals and the 0.2.0 database reset are called out, though breaking changes arrive in minor versions before 1.0 (12). Version 0.5.0, and SECURITY.md says pre-1.0 (0).

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.
