Abyssale vs Osmo CLI

Abyssale 85

API version v2026-10-29, eight days before this check (30). Fifteen dated API versions between 21 August and 29 October, MCP server releases 1.0.0 (1 September) to 1.2.0 (7 October), and SDK releases in October (20). Closed service with a changelog and RSS feed, help@abyssale.com and in-app chat, which we didn't test (12 of 15). com.abyssale/mcp is in the official MCP registry under a domain-verified namespace, and the Node.js (1.9.0) and Python (1.7.0) SDKs were both released on 21 October 2026 (15). Both SDKs are current; their repositories weren't read (8 of 10). 30 + 20 + 12 + 15 + 8 = 85.

Osmo CLI 7

No release date can be read. The 6 October date for 0.1.19 and the version timestamps came from npm's registry document, a JSON data interface this method no longer reads, so they are struck. The 0.1.19 package itself, read on 8 October, carries no release date, the CLI page and llms.txt give none, and the skill repository has no tags or versions (0). No dated release in the 90 days from 7 August can be counted for the same reason (0). No public changelog or tracker. Support is support@osmo.inc, and the skill repository has eight commits and two merged pull requests, the latest on 15 October (3). No SDKs and no MCP registry entry (0). One pinned dependency with a third-party inventory and hashes in release.json, per the 0.1.19 package read on 8 October, but no public CI. Partial kept (4). The skill now names osmo usage, absent from 0.1.19, so a later version is likely. 0 + 0 + 3 + 0 + 4 = 7.

Abyssale 98

A 424 KB OpenAPI file at developers.abyssale.com/api.yaml with 34 operations, from which the reference pages are generated (25). A detailed llms.txt that states the base URL, auth, rate limits, error envelope and webhook signing up front (10). Pages say what each endpoint is for and when to use another, such as synchronous versus asynchronous generation and designs versus workspace templates, and the MCP permissions page says what each tool can break (19 of 20). Typed parameters with enums, ranges and required fields across layers and formats (14 of 15). One error envelope everywhere, an error catalogue with machine-readable ids and what to do for each, and worked examples (15). Date-based versions named in every response and a dated changelog in Keep a Changelog form with a Breaking section first; the MCP server has its own semver changelog (15). 25 + 10 + 19 + 14 + 15 + 15 = 98.

Osmo CLI 34

API checklist adapted to a CLI. No OpenAPI or command schema is published on a docs page. The model input schemas recorded on 8 October came from the product's own catalogue API at studio.osmo.inc/api/resources, which this method no longer reads, so the contract line has nothing behind it (0). The skill's SKILL.md is Markdown written for agents, with a command table, and osmo.inc/llms.txt now links the CLI page; the package's README, SETUP.md and DEPLOY.md were read from the 0.1.19 tarball on 8 October (10). Help text in the 0.1.19 bundle states what each command is for and when to pick share over studio deploy, per the 8 October check (12). Typed inputs with enums and ranges were read only from the catalogue API, so none remain (0). An example per command and JSON output shapes in DEPLOY.md, and a command table in the skill, but no reference for the roughly 50 error codes (8). Semver versions with no changelog (4). 0 + 10 + 12 + 0 + 8 + 4 = 34.

Abyssale 71

Closed service under terms of service version 3 of 21 July 2026, from a Paris SAS with its register number (15). The privacy policy and terms agree on EU hosting on AWS Ireland, deletion timelines and breach notice within 72 hours, but AI model training on anonymised customer content is on by default with a workspace opt-out, and anonymised data may be kept indefinitely (20 of 30). The changelog has Deprecated and Removed sections and refers to a deprecation policy that covers stable endpoints but not alpha ones; the policy's notice period wasn't found (14 of 20). Subprocessors named with locations, among them AWS Ireland, Auth0, Brevo, Intercom and AI providers including OpenAI, Anthropic, Black Forest Labs and Google, some outside the EEA (20). 15 + 20 + 14 + 20 = 69.

Osmo CLI 33

Closed source. The skill README says the CLI, renderer and resource packages are proprietary, and the npm packages carried no licence field or LICENSE file on 8 October. The terms of service render only in the browser and were read on 8 October from the site's script bundle, which this method no longer reads, so no licence terms are readable (0, as for other listings whose terms were only ever read from a script bundle). The privacy policy and terms were read the same way, so no data-handling statement remains (0). No deprecation policy or dated notices (0). The CLI bundle read on 8 October contacts only studio.osmo.inc and contains no analytics hosts, though telemetry isn't documented either way; the AI providers named in the struck privacy policy no longer count. Partial kept (10). 0 + 0 + 0 + 10 = 10.

Abyssale 35

No x402, MPP or L402 (0). Seat prices are public and the credit cost of every output is published to the format, with worked examples, but a credit's price outside the plan wasn't found (15 of 20). 14-day free trial with no card (20). A person signs up in the browser; the MCP OAuth flow needs a human login (0). 0 + 15 + 20 + 0 = 35.

Osmo CLI 10

Graded on the paid hosted service the CLI depends on, by the published rubric. No x402, MPP or L402 in the OAuth metadata or the skill (0). osmo.inc/pricing, terms and privacy render only in the browser, and the 8 October prices were read from the site's script, which this method no longer reads, so no price is readable (0). The skill README says model runs use the account's plan, which includes a free monthly allowance, without saying whether a card is needed, so half (10). A person has to create an account and approve the device login in a browser (0). 0 + 0 + 10 + 0 = 10.

Abyssale 41

Hosted lines, for the REST API and the remote MCP server. No status page was linked from the site or the docs, and status.abyssale.com did not answer (0). No readable incident history (5). Rate limits published in full, 10 requests a second globally and per-workspace tiers with per-minute and per-hour budgets (15). 429s carry Retry-After and X-RateLimit headers, three 429 ids say which limit was hit, failed generations cost nothing, and webhooks carry a delivery id to deduplicate on. No idempotency key on generation requests (13 of 15). The terms promise best-effort availability and leave SLAs to Enterprise contracts, so none is published (0). Generation and the MCP server are generally available, while Design Import, the JSON authoring route, is labelled alpha (8 of 10). 0 + 5 + 15 + 13 + 0 + 8 = 41.

Osmo CLI 23

Local-package reading, since the owner runs the CLI. Installs from npm. The vendor's skill README (revised 15 October 2026) states Node 22 or later, Git 2.29 or later, FFmpeg, and Studio on Apple Silicon macOS and Linux x64 and arm64 (glibc), while the npm README read on 8 October said any OS; the current npm README couldn't be read, so 15 is kept as a partial (15). The source is private, so there is no public CI or test suite (0). No public issue tracker for the CLI. Support is an email address (5). Versions are semver-shaped with preview tags, but no changelog was found, and osmo share --video FILE in 0.1.17 became osmo share FILE by 0.1.19 without a published note (3). Version 0.1.19 on 8 October, not declared stable (0). 15 + 0 + 5 + 3 + 0 = 23.

Abyssale 85

20 MCP tools (15 for 11 to 30), plus 5 because OAuth scopes per tool group let a client be approved for reads only (20 of 25). Design listings search by words in any order, filter by project, orientation, size, format and dates, sort and order, and say honestly when a page is past the end; listing tools refuse unsupported options rather than ignore them, per MCP 1.2.0 (19 of 20). One envelope with an id to branch on, and error docs that say which errors a retry never fixes (19 of 20). The permissions page marks each tool read-only, mutating or destructive, but MCP annotations couldn't be confirmed on the closed server, and generation has no idempotency key (12 of 20). Official Node.js and Python SDKs with retry behaviour and polling helpers (15). 20 + 19 + 19 + 12 + 15 = 85.

Osmo CLI 70

Read from the 0.1.19 bundle and docs on 8 October and the skill re-read on 5 November, not from a run. The skill grew from 255 bytes to 9,686 bytes on 15 October, a compact guide with a command table, every command takes --json, and lists default to short pages (18). --limit and --cursor on lists, --type on resources and --open on comments (15). Errors are JSON with a code, a message, a next command and retryAfter where it applies, with exit code 2 for usage errors, though only one error is documented (14). osmo run sends an Idempotency-Key and retries network errors, repeating unshare is documented as safe, and a failed upload reports the share to retry against (16). Few required arguments, and no SDK in any language (7). 18 + 15 + 14 + 16 + 7 = 70.
