54027ba763 MUL-6639: fix(skills): metadata-only skill listings and stall-based timeouts (#7574)
* MUL-6639: feat(skills): list skill files as metadata, not content

`multica skill get` and `multica skill files list` both downloaded every file
body to render output that shows none of them — `skill get`'s table view prints
four columns, and the file listing prints paths and timestamps. Past a few
hundred KB that stopped being waste and became a hard failure: a 599KB skill
could not be fetched at all, and the listing that would have shown which file
was oversized required downloading all of them first, so the diagnostic died
with the thing it was meant to diagnose (GH #7498).

Both endpoints now take `?include=content|metadata`. The metadata shape carries
path, byte size and content hash per file, plus the size and hash of the
SKILL.md body — computed in Postgres, so the bodies never leave the database.
Response size now tracks file count, not content size.

`GET /api/skills/{id}/files` defaults to metadata: it is a list endpoint, the
CLI is its only caller, and `GET /api/skills` already dropped content for this
exact reason (GH #2174). `GET /api/skills/{id}` keeps returning content by
default — installed web and desktop builds call it for the skill editor and
cannot be retrofitted with a query parameter. The CLI asks for metadata on both
and takes `--with-content` when the bodies are actually wanted.

The file listing gains a SIZE column, which is what makes an oversized skill
diagnosable without downloading it.

* MUL-6639: fix(cli): fail skill transfers on stall, not elapsed time

`http.Client.Timeout` is a wall clock on the whole request, body included, so
it punishes exactly the transfer that is working: a 599KB skill arriving
steadily over a slow link was cut off at 30s mid-body, while a genuinely dead
connection was held open for the same 30s (GH #7498). Raising the constant
moves the cliff without removing it — the honest test is not "has this taken
too long?" but "is it still making progress?".

internal/cli/stall.go adds a client that asks the second question: bounded
connect, TLS and response-header phases, and a response body that fails after
15s with no new bytes. The wall clock stays as a loose 10-minute backstop —
demoted, not deleted, because dropping it to 0 would have left a stalled
request upload with no deadline at all.

Failures now say which thing went wrong. A new KindNetworkStalled reports "no
data received for 15s after N bytes" rather than a timeout, because only one of
those is fixed by waiting longer. Body-read errors are classified at all now:
wrapTransport only ever saw errors from http.Client.Do, which returns once the
headers arrive, so the failure #7498 actually reports reached users as a raw
"context deadline exceeded ... while reading body" out of the JSON decoder.

MULTICA_HTTP_STALL_TIMEOUT sets the no-progress budget. An explicitly set
MULTICA_HTTP_TIMEOUT still applies on this path, keeping its plain meaning —
the longest you will wait for a server — instead of silently reverting to a
total-elapsed limit.

Adoption starts with the skill commands, where the failure was reported; the
mechanism itself is not skill-specific. Graduation is one edit: point
NewAPIClient at NewStallAwareHTTPClient, fold StallAwareContext into
APIContext, drop newSkillAPIClient. A permanent second client would leave the
CLI with two timeout personalities, which is worse than either alone.

* MUL-6639: fix(skills): hash raw UTF-8, keep the no-include default at content

Review found two problems with the previous two commits.

**The file hash was not over the file's bytes.** `sha256(content::bytea)` runs
the bytea *input* parser over the text rather than taking its bytes, so it
reads backslash escapes: a file containing `\x41` hashed as the single byte
`A`, disagreeing silently with the Go-side hash of the SKILL.md body.

Worse than the mismatch, and not caught earlier because the first check used
accented text with no backslash in it: `content::bytea` *errors* on a bare
backslash. `C:\Users\...`, a regex `\d+`, a LaTeX snippet — ordinary contents
of a skill's supporting files — fail with "invalid input syntax for type
bytea", making the listing 500 on the skills most likely to need it.
`convert_to(content, 'UTF8')` takes the bytes, and matches Go exactly.

**`/api/skills/{id}/files` must not change what a bare request returns.** The
previous commit flipped its default to metadata on the grounds that the CLI is
its only caller. That was the wrong reading of "only caller": the CLI is
installed software too, and an older `skill files list --output json` reads
`content`. It is the same argument that kept the detail endpoint's default —
applied inconsistently to a client that upgrades separately from the server.

Both endpoints now return content when `?include=` is absent. The shrink
travels with the caller instead: the CLI sends `include=metadata` itself, so
GH #7498 is fixed with no synchronized release, and the default can flip once
clients that send `include=content` have aged in. The default is now uniform,
so resolveSkillInclude no longer takes a per-endpoint parameter.

Tests: TestSkillFileHashCoversRawUTF8Bytes covers `\x41`, invalid hex, bare
backslashes, Unicode and empty bodies against the Go hash — verified to fail on
the previous SQL. TestSkillEndpointsWithoutIncludeStillReturnContent pins the
compatibility guarantee on both endpoints.

Not addressed, and noted as follow-up: the metadata path still loads the full
SKILL.md into Go, because loadSkillForUser needs the row for its tenant check.
The HTTP response no longer grows with content; the database read still does.

617d416029 MUL-6658 fix(cli): tell a rejected task token to stop, not to sign in again (#7522) (#7532)
* fix(cli): tell a revoked task token the task is over, not to sign in again

The CLI's generic 401 copy reads "Your session has expired or you are
not signed in. Run `multica login` to sign in again. On a self-hosted or
non-OAuth setup, ask your administrator for valid credentials."

That is correct advice for a person and actively harmful for an agent. A
task's mat_ token is revoked the moment the task reaches a terminal
state, so every call an orphaned agent makes after cancellation gets that
message — and it reads as an instruction to go find a working credential.
In GH #7522 one did exactly that: it read the daemon owner's profile PAT
out of ~/.multica and kept working under the member's identity.

A 401 on a task-scoped token now says the token was revoked because the
task ended, and not to retry with another credential. The status code
alone cannot distinguish the two cases, so HTTPError records which kind
of credential the request carried; nothing else about the client is read,
and exit classification is unchanged (still ExitAuth).

This is defence in depth, not the fix for #7522 — cancellation not
terminating the process tree is (PR #7531). It removes the motive.

* fix(cli): base the task-token claim on the request, not the client

Review found three problems with the first pass.

TaskScoped read the client's own Token field, which answers "what does
this client hold", not "what did the failing request send". DownloadFile
deliberately sends no Authorization header for an absolute signed URL,
so a 401 from object storage would have been reported to an agent as a
finished task purely because the client happened to hold a mat_ token.
It now reads resp.Request, which is the request that actually went out —
also correct across a redirect that strips the header, which the
caller's own request object would not be. newHTTPError goes back to a
plain function. A test drives a real client through both paths instead
of hand-building the error, and fails if the claim moves back to client
state.

The copy asserted a cause the CLI cannot verify: 401 also covers a
malformed token, one sent to the wrong server, and one dropped by an
unrelated cleanup. It now says the token was rejected and to stop,
without naming a reason. "Stop, and do not fall back to a profile or
member credential" is true in every one of those cases; "the task
finished" is not. The kind is renamed to KindTaskTokenRejected to match.

The Chinese copy used 任务 for an agent execution. Per the glossary,
任务 is the product entity a user files (an issue) and an agent execution
stays lowercase `task`; the old wording said the user's issue was
rejected. A test now fails if 任务 reappears in this message.

* docs(cli): stop asserting the cause in the comments too

The runtime copy no longer claims why a task token was rejected, but
three comments still did: TaskTokenPrefix called a 401 "a normal
end-of-task signal", TaskScoped described the token as "finished", and
the wiring test quoted the old wording. A reader following the comments
would have reintroduced exactly the claim this PR removed.

They now say what the CLI can actually see — a task token was rejected,
there is no sign-in that brings it back, and the reason is not visible
from here.

d38da27ed4 MUL-5619: fix(cli): surface the server's 409 message instead of the generic conflict template (#6267)
* fix(cli): show the server's conflict message instead of the generic 409 template

Every 409 this API returns is a deterministic refusal that names its own fix
("a skill with this name already exists", "set parent_id (--parent) to <id>").
The CLI replaced all of them with a template that says the opposite — that the
state changed underneath you and you should re-fetch and retry. Agents took the
retry hint literally: GH #6264 reports 15+ identical retries over 10 minutes
followed by hours spent chasing an optimistic-concurrency theory that never
existed, and GH #5948 is a second user misdiagnosing the same way. MUL-4417 had
already written the useful message server-side; it just never reached anyone.

Route 409 through the same server-message extraction 400/422 already uses, so
roughly forty hand-written conflict messages across skills, agents, runtimes,
labels, projects and comments become visible by default. A body we cannot
recognize still falls back to the template, so this never dumps a raw response.

extractServerMessage now prefers prose over a bare identifier, because a few
endpoints put a stable code in "error" and the sentence in "message".

* fix(comments): stop telling a wrong --parent that it posted a top-level comment

The reply guard returns one message for two different mistakes. A resumed
session that carries a previous turn's --parent forward (GH #6264) did not ask
for a top-level comment, but is told it did — which sends it looking for a
new-thread opt-in (GH #5383) instead of correcting the parent it already passed.

Split the copy: name the rejected parent when one was supplied, and keep the
existing top-level wording for the parentless case. Both still point at the
trigger comment to use.

* fix(runtime): return 500, not a 409 echo, when the update store fails

InitiateUpdate answered every UpdateStore.Create failure with a 409 carrying
err.Error(). The in-memory store only ever returns errUpdateInProgress, so this
looked safe — but the Redis store also wraps infrastructure failures as
"reserve active update: <dial error>" and "persist update request: <error>".

Surfacing 409 bodies in the CLI turns that into a user-visible leak of internal
addresses, and labels an outage as a conflict the caller could fix by retrying.
Classify instead: errUpdateInProgress keeps its 409 and its actionable message,
everything else is logged and answered with a 500 and fixed copy.

Also pins the prose-over-machine-code preference for validation bodies, which
the shared extractor applies to 400/422 as well as 409. Only the issue-table
endpoints are shaped that way and none is reachable from the CLI today, but the
change is intentional and should fail loudly if reverted.

LinYushenandmultica-agent 9ff801f926 docs(cli): error-message conventions + sign-in copy (PR3, MUL-3104) (#3900)
* docs(cli): add Error Messages conventions + refine sign-in copy (PR3)

Final pass of the CLI error-message work (MUL-3104).

- CLI_AND_DAEMON.md: new "Error Messages" section documenting the user-facing
  contract — friendly single-line messages, server validation passthrough,
  English default with automatic Chinese on a zh locale, the tiered exit codes
  (0/1/2/3/4/5), --debug / MULTICA_DEBUG for the full chain, and
  MULTICA_HTTP_TIMEOUT.
- cmd_auth.go: clarify three high-frequency sign-in errors so the message
  states what failed and the next step — local login-callback server start
  (hints at port/firewall), access-token creation, and token verification
  (suggests retrying `multica login` and checking the token is valid/not
  expired). All keep %w so exit-code tiering and --debug detail are preserved.

cmd_id_resolver.go is left as-is — its not-found / ambiguous-prefix messages
already point at `list --full-id` and need no change. The user-facing
FormatError layer is unchanged, so its existing PR1/PR2 test coverage still
applies; no test asserted the old verb strings.

* fix(cli): make login failure guidance visible via typed user-message wrapper

Addresses 张大彪's PR3 review: the refined sign-in copy was wrapped with %w,
so FormatError returned the centralized *HTTPError/*NetworkError copy and the
new guidance only appeared under --debug.

- Add cli.UserMessageError + cli.WithUserMessage: a typed wrapper carrying a
  user-facing message that FormatError surfaces by default, recognized before
  the network/http branches. Unwrap() is preserved, so ExitCodeFor still
  classifies by the underlying typed error and --debug still prints the full
  original chain.
- cmd_auth.go: wrap the OAuth access-token-creation and PAT-verification
  failures with WithUserMessage (OAuth copy no longer mentions a passed token,
  since that flow has none), and move the token-specific 'valid / not expired'
  hint to the real Enter your personal access token:  verification site (was the generic
  'invalid token: %w').
- Focused tests: under a wrapped *HTTPError(401) the default FormatError shows
  the login hint, ExitCodeFor returns ExitAuth, and --debug retains the raw
  chain; a wrapped *NetworkError still classifies as ExitNetwork.
- CLI_AND_DAEMON.md: narrow 'every error' to command errors returned to the
  top-level handler, noting commands like setup's fast /health probe bypass it.

LinYushenandmultica-agent b83b41ff44 feat(cli): per-status error copy with actionable hints (PR2, MUL-3104) (#3897)
* feat(cli): refine per-status error copy with actionable hints (PR2)

Builds on PR1's translation layer. Each HTTP-status message now carries an
actionable next step, in both English and Chinese:

- 401: run `multica login`; plus a self-hosted / non-OAuth fallback telling
  the user to ask their administrator for valid credentials
- 403: check the workspace / ask an admin to grant access
- 404: check the ID or run the matching `list` command
- 409: re-fetch the latest state and retry
- 422: check values / run with --help
- 429: wait and retry; reduce call frequency if it persists
- 5xx: retry, contact support, and re-run with --debug for the raw response

Also adds ErrorKind.String() (stable snake_case identifiers) and uses it in
--debug output instead of the raw int, and clears the pre-existing gofmt dirt
Eve flagged in cmd_config.go, cmd_version.go, and help.go.

Tests: TestErrorKindString (all kinds + uniqueness + out-of-range fallback)
and TestFormatErrorActionableHints (locks the per-status hints in EN and ZH).

* test(cli): cover validation (400/422) actionable hint

TestFormatErrorActionableHints omitted KindValidation, so deleting the 400/422
hint would have gone unnoticed. Add 400 and 422 cases (no server message, so
the generic validation copy is used) asserting EN contains --help / expected
format and ZH contains --help / 格式 / 参数.

LinYushenandmultica-agent 28de8b8bde feat(cli): central error translation layer (PR1, MUL-3104) (#3892)
* feat(cli): add central error translation layer (PR1)

Introduce server/internal/cli/errors.go, a single user-facing error
translation layer that collapses raw transport errors, HTTP status
errors, and internal verb-wrapped chains into clear, localized messages.

- ErrorKind classification (network timeout/DNS/refused/TLS/offline,
  401/403/404/409/400+422/429/5xx, unknown)
- NetworkError wraps transport errors and strips the raw URL from the
  user-facing message; classifyNetworkError categorizes via errors.As/Is
  with string fallbacks
- HTTPError.Kind() maps status codes onto ErrorKind
- FormatError: bilingual output (English default, auto-switch to Chinese
  on a zh LC_ALL/LC_MESSAGES/LANG locale), validation errors surface the
  server message; --debug / MULTICA_DEBUG appends the full raw chain
- ExitCodeFor: tiered exit codes (network=2, auth=3, 404=4, validation=5,
  other=1)
- client.go: default HTTP timeout 15s -> 30s, overridable via
  MULTICA_HTTP_TIMEOUT; wrap every transport Do() error as *NetworkError
- main.go: route errors through FormatError + ExitCodeFor, add persistent
  --debug flag

Unit tests cover every ErrorKind, classification, language detection,
exit codes, server-message extraction, and timeout parsing.

* fix(cli): address review — unify command timeouts and classify all helper errors

Must-fix 1: command-level contexts no longer truncate MULTICA_HTTP_TIMEOUT.
Added cli.APITimeout/AtLeastAPITimeout/APIContext (budget = transport timeout
+ small grace, honoring MULTICA_HTTP_TIMEOUT) and replaced the hardcoded 15s
context.WithTimeout in every API command (14 files, 92 sites) with
cli.APIContext. The issue-create/comment path now uses APITimeout() with a
60s floor for attachment uploads.

Must-fix 2: all API helpers now return *HTTPError on status >= 400. Added a
shared newHTTPError(method, path, resp) and routed GetJSON, GetJSONWithHeaders,
PostJSON, PutJSON, PatchJSON, DeleteJSON, DeleteJSONWithBody, UploadFile,
UploadFileWithURL, DownloadFile (and HealthCheck) through it, so issue
update/status/metadata (PUT), comment list (GetJSONWithHeaders), project/label/
comment delete (DELETE) and agent/workspace/autopilot update (PUT/PATCH) all
get HTTPError.Kind() classification, friendly copy, and the tiered exit code
instead of the raw string + exit 1.

Tests: new errors_integration_test.go drives the real helpers against a fake
server and asserts FormatError copy + ExitCodeFor for 401/403/404/422/500
across all 10 helpers, plus a slow-server test proving the command context
does not cancel before the transport timeout. Updated the UploadFileWithURL
assertion to check for *HTTPError.

* fix(cli): make remaining fixed-timeout API commands honor MULTICA_HTTP_TIMEOUT

Closes out the timeout work: the last API command paths still used a
hardcoded context deadline that capped MULTICA_HTTP_TIMEOUT. Converted them
to cli.AtLeastAPITimeout(<original floor>) so the env override scales them up
while preserving each original lower bound:

- cmd_autopilot.go  autopilot trigger      30s -> AtLeastAPITimeout(30s)
- cmd_attachment.go attachment download    60s -> AtLeastAPITimeout(60s)
- cmd_agent.go      avatar upload           60s -> AtLeastAPITimeout(60s)
- cmd_skill.go      skill import / search    60s -> AtLeastAPITimeout(60s)
- cmd_runtime.go    runtime update         150s -> AtLeastAPITimeout(150s)
- cmd_login.go      workspace-creation poll 10s -> AtLeastAPITimeout(10s)

The login poll keeps a short 10s floor to stay responsive within its 5-minute
loop, but it is NOT a silent exception: AtLeastAPITimeout means it still scales
with MULTICA_HTTP_TIMEOUT. Documented in code and covered by a new subtest in
TestAPITimeoutRespectsEnv.
