A `perspective` command for the External REST API and the hosted MCP server, built for humans and coding agents alike: JSON on stdout, JSON errors on stderr, stable exit codes. - auth: browser OAuth (PKCE, loopback redirect) for MCP tools, API key (stdin, validated) for REST; flag > env > file precedence; tokens refresh automatically; credentials file is 0600. - REST: workspaces list, funnels list, contacts list/get/create/set, metrics kpi/chart/insight/subtypes. - tools list/describe/call: generic access to every MCP tool, with a minimal stateless JSON-RPC client (JSON and SSE replies). - skill show/install and skills/perspective/SKILL.md. - Vitest suite and a CI workflow on Node 22 and 24.

Explanation
[CAP-4819] The PR adds the TypeScript CLI for Node.js ��22.12. It implements API-key login by flag, prompt, and stdin, validation, credential storage, and
PERSPECTIVE_API_KEY. It adds workspaces, contacts, and metrics REST commands. It implements JSON output, JSON errors on stderr, stable exit codes, andSKILL.md. The reported typecheck, 33 tests, and production read-command checks support these requirements. MCP, OAuth, npm publishing, and release automation remain excluded. The developer-docs PR is a non-coding deliverable and is not assessed here.

Comment @coderabbitai help to get the list of available commands.
Drops the MCP client, the OAuth browser login and the `tools` commands. `auth login` now stores an API key: it prompts on a terminal, reads stdin when piped, or takes --api-key, and validates the key first. `auth token`, --token and PERSPECTIVE_TOKEN are gone. SKILL.md, README and AGENTS.md describe the API-only scope. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
readline redrew the line (cursor to column 1, clear to end of screen), wiping "API key: " right after it was printed. Read the key in raw mode instead, explain where to get one before prompting, and exit 130 on Ctrl+C. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Tested against production: the API reports `live`, not `online` (the swagger enum is wrong), so `funnels list --status online` silently returned nothing. --status now only accepts draft, live or offline. A wrong funnel ID returns 403 "User has no access to campaign"; the hint blamed only key permissions. It now suggests checking the ID too. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- --fields (global): keep only the listed fields of each result; dots reach into nested objects and keep the dotted name; meta is kept, and missing fields are null so every item has the same keys. - --dry-run on `contacts create` and `contacts set`: print the method, URL and body instead of sending; needs no API key. - RestClient retries HTTP 429 up to 3 times, waiting Retry-After (or RateLimit-Reset, else 2^n s), at most a minute. A 429 means the request was not processed, so this is safe for writes too. SKILL.md now tells agents to dry-run writes and show the request before confirming, and to use --fields on large lists.

- `metrics kpi <funnelId> <subtypes...>` takes several KPI names or
`all`. One KPI still prints the API response as-is; several print
{data: [...]} in the order given (requests run in parallel).
- Parse errors (unknown option or command, missing argument, invalid
choice) are now JSON on stderr with exit 2, like every other error.
Help and version output are unchanged.
- SKILL.md documents what each KPI value means (percent, seconds,
count; the time KPIs are medians, checked in perspective-metrics),
tells agents to fetch total_sessions before ranking rates, and that
insight IDs must come from the user.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.Reject an invalid window when
--fromis given without--toand--daysis irrelevant.If
--fromis set,--daysis ignored. This matches the option description, so no defect exists there.The
--fromand--tovalues go throughnew Date(value). A date-only string such as2026-01-01parses as UTC midnight. A string such as2026-01-01T00:00(no offset) parses as local time. The two forms give different windows for the same visible date. The CLI help says only "ISO 8601". Document this difference, or reject strings without an explicit offset.

Inline comments:
Review comments at @skills/perspective/SKILL.md:
- Line 20: Update the authentication guidance near the authenticated status
behavior to state that only API-backed commands require authentication;
explicitly indicate that skill show and skill install remain available without
an API key, and remove the claim that every other command fails with exit code
3.
Review comments at @src/commands/metrics.ts:
- Line 64: Update the --tz-offset option parser to validate integer syntax with
the existing parseInteger helper before resolveWindow and the API request,
preserving the value as a string and avoiding any undocumented range
restriction.
Review comments at @src/commands/skill.ts:
- Around line 16-18: Update the skill show command’s description and handler to
use the existing action wrapper, returning the SKILL.md contents in a skill JSON
field instead of writing raw markdown to stdout. Preserve readFile error
propagation through the command’s existing parseAsync error handling.
- Line 35: Update the skill installation flow around writeFile and SKILL_SOURCE
to write the content to a temporary file in target’s directory, rename it over
target only after the write succeeds, and remove the temporary file if any step
fails.
Review comments at @src/config.ts:
- Around line 22-29: Update loadConfig to parse credentials content separately
and validate that the result is a non-null, non-array object. Convert invalid
JSON and invalid top-level values into a CliError that includes the config path
and directs users to perspective auth logout, while preserving the ENOENT
empty-config behavior and rethrowing unrelated file-read errors.
Review comments at @src/context.ts:
- Around line 30-37: Update the baseUrl method to treat empty option,
environment, and stored values as unset by using truthy fallback selection, then
validate the resolved URL before normalization with URL.canParse. For invalid
values, throw the established CliError with the usage category and include the
invalid URL; preserve the existing trailing-slash removal for valid URLs.
Review comments at @src/input.ts:
- Around line 43-47: Update the JSON parsing logic in the input value handling
around JSON.parse so numeric literals retain their original text when JavaScript
parsing cannot represent their exact value. Use a numeric exact-value comparison
that ignores harmless formatting differences such as 1e3, 1.0, and -0, and only
preserve the raw trimmed text when the parsed number’s value changes; leave
nonnumeric JSON and plain-string handling unchanged.
Review comments at @src/rest.ts:
- Around line 63-72: Update the request options in the method containing
fetchImpl to pass an AbortSignal.timeout using a 30-second REQUEST_TIMEOUT_MS
constant, allowing stalled calls to reach the existing catch path and surface as
network errors. Keep the current request construction and error handling
unchanged.

- 30 s request timeout per attempt, reported as a network error (exit 7)
- empty base URL counts as unset; an invalid one is a usage error, not network
- a broken credentials file is a CliError that points to auth logout
- --tz-offset must be an integer
- --set keeps integers a double can't hold exactly (long IDs) as text
- skill show returns {path, content} JSON; skill install replaces SKILL.md atomically
- SKILL.md: skill commands work without an API key

What
The first version of
perspective, a CLI that wraps the External API (/v1). It is built for both people and coding agents:{"error":{code,message,status?,hint?}}.auth login/status/logoutGET /v1/workspacesworkspaces list,funnels listGET /v1/workspacescontacts list [--all] / get / create / set/v1/funnels/{id}/contacts…metrics kpi <subtypes…|all> / chart / insight / subtypes/v1/funnels/{id}/metrics/…skill show / installskills/perspective/SKILL.mdDesign notes
auth loginprompts for the key on a terminal (input hidden), reads it from stdin when piped, or takes--api-key. It validates the key before storing it in~/.config/perspective/credentials.json(0600). The key resolves in this order:--api-keyflag, thenPERSPECTIVE_API_KEY, then the file.--fields(global) keeps only the listed fields, so a large list doesn't flood an agent's context.--dry-runoncontacts create/setprints the request without sending it. HTTP 429 is retried up to 3 times, waitingRetry-After(at most a minute).metrics kpitakes several KPIs orallin one call. Parse errors (unknown option or command, missing argument) are JSON too.commanderis the only runtime dependency.auth statusfirstfunnels listcontacts create/setand show the request before sending, because they can trigger automations and emails; and offer--skip-automation--fieldson large liststotal_sessionsbefore ranking rates.@perspective-software/cli(public).
