Introduce a typed error contract framework for lark-cli so in-process
Go callers can branch via errors.As(&errs.XxxError{}) and shell scripts,
AI agents, and protocol adapters can branch on stable JSON type/subtype
fields instead of regex-parsing free-form messages.
Adds:
- Canonical taxonomy under errs/ (9 categories + typed Error structs
embedding a shared Problem, RFC 7807-aligned)
- Centralized Lark code metadata + identity-aware BuildAPIError dispatch
- Typed JSON envelope writer alongside the legacy envelope writer
- MCP / OAuth (RFC 6750 Bearer) projection adapters
- Five CI lint guards preventing ad-hoc taxonomy drift
Backward compatibility: legacy *output.ExitError producers (ErrAPI,
ErrWithHint, Errorf, ErrBare) and business shortcuts that use them
continue to render the legacy envelope unchanged. SecurityPolicyError
wire format and exit code are preserved via a carve-out; taxonomy
migration is deferred to PR 2. Domain-specific business migration is
staged across PR 3+.
Framework-direct paths now return typed *errs.*Error: ErrAuth /
ErrValidation / ErrNetwork emit category literals on the wire
(authentication / validation / network), *core.ConfigError is promoted
at the cmd/root boundary with exit code aligned from 2 to 3, and Lark
API permission denials classified by BuildAPIError exit 3.
At the SDK boundary, WrapDoAPIError preserves any already-classified
error (legacy *output.ExitError or typed *errs.*) so output.ErrAuth
from missing credentials surfaces with the auth category and exit 3
intact instead of being downgraded to a network error. Policy responses
classified by BuildAPIError (codes 21000 / 21001) extract challenge_url
and the canonical hint from the response body, matching what the
auth transport already surfaces at the HTTP layer; non-https
challenge URLs are dropped.
First PR in the feat/error-contract-* series.
AI agents running inside OpenClaw / Hermes were routinely creating a parallel
app via `config init --new` instead of binding to the agent's existing app,
because every "not configured" hint and several deny errors hard-coded
`config init` regardless of workspace. Once bound, the same agents could
silently grant themselves user identity (impersonation) without the user
ever seeing a risk message in chat.
Changes:
- Introduce `core.NotConfiguredError` / `NoActiveProfileError` /
`reconfigureHint` helpers that branch on `CurrentWorkspace()`. In agent
workspaces they point at `lark-cli config bind --help` (a help page, not
a ready-to-run command) so AI must read the binding workflow and confirm
identity preset with the user before acting. In local terminals they
preserve the previous `config init --new` guidance.
- Migrate every `config init` hint that should be workspace-aware:
RequireConfigForProfile, default credential provider, credential provider
fallback, secret-resolve mismatch, config show, strict-mode entry-point
errors, default-as, profile use/rename/remove, auth list, doctor's
config_file check (which now also wraps the OS-level "no such file"
noise into the user-shaped "not configured" message).
- Refuse `config init` when run inside an OpenClaw / Hermes workspace by
default; add `--force-init` for the rare case the user genuinely wants
a parallel app. Without this guard, hint fixes were undone the moment
AI ignored them.
- Rewrite the strict-mode deny errors in cmd/auth/login.go, cmd/prune.go,
and internal/cmdutil/factory.go. The previous "AI agents are strictly
prohibited from modifying this setting" terminated AI reasoning while
providing no real gate. New errors point at `config strict-mode --help`
with the legitimate confirmation flow and explicitly note that switching
does NOT require re-bind. Integration test envelopes updated.
- Tighten `config bind --help` and `config strict-mode --help` to encode
the user-confirmation discipline directly: identity preset semantics
(bot-only vs user-default), "DO NOT switch without explicit user
confirmation", and a cross-reference clarifying that `config bind` is
for changing the underlying app while `config strict-mode` is the
policy-only switch (resolves an ambiguity an audit run found).
- Surface user-identity (impersonation) risk at every config write that
newly grants it, by reusing the canonical IdentityEscalationMessage
string from bind_messages.go:
- `noticeUserDefaultRisk` fires on flag-mode bind landing on
user-default, including the first-time case `warnIdentityEscalation`
misses (it requires a previous bot lock).
- `setStrictMode` warns when transitioning bot → user or bot → off
(newly permits user identity); stays quiet on narrowing changes
and on off → user (off already permitted user).
- Add tests: notconfigured_test.go (workspace branches),
init_guard_test.go (refuse + --force-init bypass), bind_warning_test.go
(user-default warning fires; bot-only does not), strict_mode_warning_test.go
(5 transitions covering both warn and no-warn paths).
Two follow-ups intentionally deferred: the keychain master-key hint at
internal/keychain/keychain.go:42 still suggests `config init` because the
keychain package can't import core (would be circular); fixing requires
either parameterizing the hint via callback or extracting workspace into
its own package. The lark-shared skill doc still tells AI to run
`config init` for first-time setup; updating the skill is in scope for
a follow-up PR.
