nullkey 2ee9741fa1 refactor(cli): finish context→profile cascade + post-review hardening (BREAKING)
Post-review polish on the v0.7 wire / surface contract. Bundles five
follow-ups that landed after the main BREAKING feat commit:

1. Complete context→profile cascade (internal API + YAML schema)

The prior commit renamed only the user-visible surface (commands /
flags / env / project link / envelope field). The internal Go API
and on-disk config schema were still half-renamed — an L-25
self-consistency violation flagged by post-merge review. Closed here:

Internal Go API:
- config.Context           → config.Profile
- config.Config.CurrentContext → CurrentProfile
- config.Config.Contexts       → Profiles
- LoginOptions.Context     → LoginOptions.Profile
- clearContextSecrets()    → clearProfileSecrets()
- saveContextRef()         → saveProfileRef()
- secrets.Store: param name `context` → `profile` (interface +
  FileStore + KeyringStore + MemStore)
- cmdutil.LoadSecret(store, context, key) → LoadSecret(store, profile, key)
- cmdutil.RefreshAndPersist's ctxName → profileName
- Local var `ctx := &config.Profile{...}` → `prof := &config.Profile{...}`
  in auth/login.go to eliminate the visual collision with Go stdlib
  context.Context that motivated the whole rename in the first place.

On-disk config.yaml schema:
- current_context: → current_profile:
- contexts:       → profiles:
- Pre-1.0 break, no compat alias. Users on v0.6 dogfooded configs
  must delete ~/.config/weknora/config.yaml or hand-rename the two
  keys (CHANGELOG migration note added).

Tests / fixtures / golden files:
- factory_test.go YAML fixture + assertion updated.
- acceptance/e2e/e2e_test.go writeContextYAML → writeProfileYAML,
  fixture YAML keys updated.
- acceptance/testdata/wire/doctor.error_network.json golden updated
  ("active context" → "active profile" in hint string).

User-visible prose sweep:
- cmd/mcp/serve.go --help Long: "active context (or --context)" →
  "active profile (or --profile)" — most-visible miss.
- cmd/{kb/list, search/kb, session/list, api/api} Short/Long help.
- cmd/auth/login.go stdout: `(context=%s)` → `(profile=%s)`.
- cmd/auth/logout.go error: `"no current context"` → `"no current profile"`.
- cmd/doctor/doctor.go hint string (also the wire golden above).
- cmd/auth/refresh.go error: `"refresh token missing for context"` →
  `"refresh token missing for profile"`.
- README.md: `## Multi-context` H2 → `## Multi-profile`; code-block
  comment `# current context` → `# current profile`.

Code-comment / docstring sweep across cli/cmd/auth/ and
cli/internal/cmdutil/. Comments referencing Go stdlib context.Context,
the RAG / LLM "context window" concept, and historical CHANGELOG
entries for v0.4 / v0.5 were left alone.

CHANGELOG v0.7 BREAKING entry gains the on-disk-schema bullet under
the existing "context → profile" item.

2. Profile name validation (shell-injection guard)

`envelope.error.retry_command` is a single shell-string field. An
AI agent that exec()s it via `sh -c <retry_command>` was injectable
through a maliciously-named profile:

  weknora auth logout --name 'x; rm -rf ~'
  # would produce: retry_command = "weknora auth logout --name x; rm -rf ~ -y"

`cmd/profile/add.go` already enforced an alphanumeric + `-_.`
allowlist via `validateName`. The `auth login` and `auth logout`
paths bypassed it.

- Moved validation from `cmd/profile/add.go` to
  `cli/internal/cmdutil/profilename.go` as exported
  `ValidateProfileName` (cmdutil is the import-cycle-safe home;
  internal/config can't depend on cmdutil).
- `auth login` runs the validator before any persist call.
- `auth logout` runs the validator on `opts.Name` before
  constructing `retry_command`.
- Unit tests (`profilename_test.go`) cover the allowlist, empty
  rejection, path-traversal, shell metacharacters (`;`, `&`, `|`,
  `$()`, backticks, quotes, whitespace, glob, redirects), and the
  user-facing hint text. The shell-metachar test exists as a
  regression guard.

Wire shape (`retry_command` string → `retry_command_argv []string`)
remains a v0.8 additive change per ROADMAP — this fix removes the
practical exploit path without touching the wire contract.

3. AI-agent terminology disambiguation

"agent" has three referents in this codebase: (a) WeKnora's
server-side Custom Agent resource, (b) the removed `agent invoke`
verb, (c) external LLM/automation consumers. Per project memory
feedback_no_meta_disambiguation_in_docs, the fix is full-term
naming, not "X has N meanings" prose. Surgical changes at section
headers + ambiguous prose:

- AGENTS.md: "Agent decision shortcuts" → "AI agent decision
  shortcuts"; "agent-callable surface" → "AI-agent-callable
  surface".
- README.md: "Designed to be agent-first" → "AI-agent-first";
  "Other agent ergonomics" → "Other AI-agent ergonomics"; "in
  agent contexts" → "in AI-agent contexts"; "for CI / agents" →
  "for CI / AI agents".

Anaphoric "agents" inside paragraphs that already established
"AI agents" was left alone — full substitution everywhere would
have been prose noise without clarity gain.

4. Wire-contract review follow-ups

Real findings from a second-pass review of the v0.7 envelope /
streaming / surface design. Per project memory
feedback_check_in_domain_anchor_first, candidate findings were
first verified against the in-domain peer CLI explicitly cited as
the envelope anchor; two earlier-flagged issues turned out to be
in-pattern and were withdrawn.

Surviving fixes:

- AGENTS.md success-envelope example rewritten. The prior example
  showed `has_more: false` / `_notice: {}` as if they were always
  present, but both fields are `omitempty` and never serialize
  when zero / nil. Replaced with three realistic shapes (list /
  single resource / mutation with no payload) and added a note
  that optional fields are omitted when empty.

- cmd/chat/chat.go Args: MinimumNArgs(1) → ExactArgs(1).
  v0.6 silently joined `weknora chat hello world` into
  `"hello world"`. v0.7 now rejects multi-arg with exit 2,
  matching `weknora session ask`. BREAKING; CHANGELOG entry
  added under v0.7 BREAKING.

- internal/output/envelope.go extracts NewEnvelope(data, meta,
  profile) constructor. The jq-filter path in
  cmdutil.FormatOptions.Emit was manually rebuilding the
  envelope literal alongside the canonical WriteEnvelope path —
  drift risk when fields are added. Single construction point now.

- internal/cmdutil/factory.go adds AddKBFlag(cmd) helper.
  Five files (chat, doc/list, doc/upload, doc/create, doc/fetch)
  had verbatim-identical `cmd.Flags().String("kb", ...)`
  declarations. Centralised so flag name + help text stay
  in sync with Factory.ResolveKB. Docstring reordering + gofmt
  fixup landed in the same edit to keep ResolveKB's own godoc
  attached to its function.

5. OSS-readiness comment / doc sweep

Pre-publication scrub of code, comments, and shipped Markdown to
remove references that only make sense in the development repo:

- AGENTS.md "Deliberate deviations + mainstream alignments"
  section: removed peer-project name-drops from the comparison
  table; rewrote as five flagged design decisions with rationale
  but no specific competitor named. The four rows that previously
  contrasted against a named peer CLI now state WeKnora's choice
  + rationale directly. Section header renamed to "Design
  decisions worth flagging" since it is no longer a
  deviation/alignment matrix.

- CHANGELOG v0.7 BREAKING rationales: three references to a
  named peer CLI removed; the context→profile rationale now
  cites only mainstream multi-credential CLIs by category (AWS /
  Stripe / OpenAI / Anthropic), and the `api -d/--data` removal
  rationale cites only `gh api` / `curl`. `chat` BREAKING entry
  rationale similarly simplified.

- 35 cross-references to design-spec section numbers (§4.1 /
  §4.5 / §5.3 etc.) removed from Go doc comments and test
  comments across 13 files. The referenced spec lives outside
  the shipped tree; readers of the public repo cannot resolve
  them. Each reference replaced with a self-contained semantic
  description (e.g. "the batch envelope" / "AGENTS.md section
  on the success path").

- Mixed-language strings translated to English:
  - Four Go comments: internal/cmdutil/exit.go:213,215,
    internal/cmdutil/errors.go:156,
    internal/output/batch_test.go:90,
    internal/output/envelope_test.go:27.
  - One CHANGELOG section title:
    `v0.7 — Agent-first wire contract + 命令面集中清理` →
    `... + command-surface cleanup`.
  - CJK test fixtures (internal/text/truncate_test.go CJK
    truncation cases, cmd/session/list_test.go Chinese session
    title, acceptance/e2e/e2e_test.go Chinese RAG corpus)
    retained — they are intentional test inputs, not stray prose.

- Makefile help comment: `golangci-lint added in PR-9` →
  `golangci-lint planned`. Internal PR numbering should not
  surface in shipped Makefile prose.

Build green, 28/28 packages, +5 new ValidateProfileName tests.
go vet / gofmt / go mod verify / go mod tidy all clean.

Rationale for the cascade: pre-1.0 is the cheapest moment to close
L-25 self-consistency (L-26). The half-finished internal rename
would have perpetuated the very `context` vs `context.Context`
ambiguity that motivated v0.7's user-visible rename in the first
place.

nullkey ad150c7126 refactor(cli): envelope sweep — Emit shape, batch ops, MCP StructuredContent, api flag cleanup
Sweep every CLI output path through the v0.7 envelope contract.

FormatOptions.Emit signature changes to (w, data, meta *output.Meta)
so list commands surface meta.count / has_more in the wire envelope.
TTY indent decision plumbed via FormatOptions.TTY (set by
ResolveDefault). --format and --jq promoted to persistent root flags
so unknown-subcommand paths still reach the typed-envelope guard
(per-command registration would have rejected --format on unknown
commands as cobra-prose exit 2). WEKNORA_FORMAT env-var fallback
honored before TTY-resolved default. AddFormatFlag retained for the
per-command --jq field-hint Long-text addendum.

~55 production Emit call sites swept across cli/cmd/**: list paths
populate meta.count; mutation paths pass nil meta; envelope.profile
threaded via globalProfile. Existing JSON-shape tests migrated to
decode the envelope wrapper.

Multi-target batch operations get a unified shape via new helpers:
- output.BatchItem + output.WriteBatchEnvelope (§4.5 per-item ok
  pattern; data:[{id, ok, result?|error?}], meta:{count, successes*,
  failures*}; Successes/Failures *int so explicit zero survives
  omitempty in all-fail case).
- cmdutil.RunBatch + cmdutil.EmitBatch + cmdutil.DeletedAtNow +
  cmdutil.ClassifyContextErr collapse the three previously-duplicated
  multi-delete pipelines (doc / chunk / session) into one call site
  pattern. doc upload --recursive uses the same helpers with a per-
  file resultFn. Summary error sets Silent:true so the stderr
  envelope path doesn't duplicate the stdout batch detail (exit 1
  preserved via Code → ExitCode).

ConfirmDestructive / ConfirmDestructiveBatch extended with action +
retryCmd parameters. Every destructive command (kb delete, kb edit,
doc delete, doc delete --all, agent delete, agent edit, session
delete, chunk delete, auth logout, api -X DELETE) now attaches
error.risk.{level:"destructive", action:"<noun.verb>"} +
error.retry_command on the exit-10 envelope. kb edit / agent edit
also gain the destructive guard wiring (CHANGELOG listed them as
gated but they were silently executing without -y).

MCP tool handlers' 31 error paths return CallToolResult with
IsError + Content text fallback + StructuredContent (envelope.error
shape via cmdutil.ErrorToDetail). Handler Out type changed from
typed *sdk.X to any so the go-sdk auto-marshal doesn't overwrite
StructuredContent with a zero-struct on error returns. Success path
manually populates CallToolResult.StructuredContent via successResult
helper.

weknora api cleanup:
- -d/--data flag removed; body via --input <file> or --input -
  (stdin) only. Aligns with gh / curl convention.
- HTTP method whitelist removed; any non-empty method accepted.
- HTTP Retry-After header → cmdutil.Error.RetryAfterSeconds →
  envelope.error.retry_after_seconds.
- runAPIPaginated raw-passthrough fallback now wraps response in
  envelope so --paginate never emits bare JSON to stdout.

Test sweep: ~60 cmd/** tests migrated to decode envelope shape.
9 wire-contract goldens updated under cli/acceptance/testdata/wire/.

nullkey f2e8e3f56c refactor(cli): drop aiclient package; align AGENTS.md with mainstream
Survey of 10 mainstream CLIs (gh, lark, stripe, vercel, supabase, aws,
azure, gcloud, openai/codex, github-copilot-cli) showed env-gated
per-command --help blurbs are a Stripe-only pattern; gh uses env detect
for telemetry only, and lark relies on installed agent Skills + MCP.
Our cmd/mcp/serve already covers the dominant 2025/26 path, so
internal/aiclient/ (136 LOC + 38 callsites) is net maintenance burden
without precedent.

- Drop internal/aiclient/ entirely (annotations + detect + tests)
- Remove 38 SetAgentHelp callsites + agentAwareHelpFunc / SetHelpFunc
  wiring in cmd/root.go
- Migrate 4 command-level rules to standard Long help (visible to all,
  not env-gated): doc upload mode mutex, kb edit at-least-one,
  kb pin idempotent, search chunks channel mutex
- Rewrite AGENTS.md as a developer guide (gh-style 6 H2 / 167 lines):
  audience preamble + Build / Architecture / Command Structure /
  Testing / Code Style / Error Handling. Drops sections absent in
  surveyed projects (Commit & PR Conventions, Who Uses This CLI)
- Clean 14 internal doc refs (ADR-N, spec §X, v0.X) in source comments
  and docs that pointed at docs/superpowers/ — that directory is
  local-only / uncommitted, so refs are dead for outside readers
- Drop forward-looking "once v0.2 ships" from README

nullkey e623e8208f refactor(cli): delete envelope infrastructure, errors to stderr
Removes the entire envelope machinery now that every success path
emits bare JSON:

- cli/internal/format/envelope.go (Envelope, Success, Failure,
  SuccessWithRisk, WriteEnvelope, Meta, Notice, UpdateNotice,
  VersionSkewNotice, Risk, RiskLevel, ErrorBody) + tests.
- cli/internal/format/filter.go envelope-specific helpers
  (WriteEnvelopeFiltered, marshalEnvelope, applyFieldFilter,
  filterDataPayload, filterObjectData); the reusable
  filterArrayItems / filterObjectKeys / writeJQ stay for bare.go.
- cli/internal/cmdutil/exporter.go + tests (envelope-only).
- cli/internal/cmdutil/PrintErrorEnvelope + ToErrorBody +
  operationRiskOf + Error.OperationRisk field + OperationRisk struct.

Error path: all errors now go to stderr via cmdutil.PrintError in
`code: message\nhint: ...` form, regardless of --json. Stdout stays
empty (or holds the partial-success the command already wrote) so
downstream `--json | jq` pipelines never have to filter error shapes
out of the success stream. Typed exit codes (3 auth.* / 4
resource.not_found / 5 input.* / 6 server.rate_limited / 7 server.*
+ network.* / 10 input.confirmation_required) carry the failure
class for agents that branch on it.

Acceptance contract:
- envelope_test.go → wire_test.go (TestEnvelopeGolden → TestWireGolden).
- testdata/envelopes/ → testdata/wire/.
- Error-path cases assert the typed code substring on stderr.
- Orphan whoami.*.json goldens deleted.

AGENTS.md + README.md rewritten for the bare-data contract:
- Drop envelope schema section + dry-run rule.
- Document bare JSON on stdout + `code: msg\nhint: …` on stderr.
- ADR-3 reframed around bare data and why error separation matters
  for `--json | jq` pipelines.

WriteJSONFiltered short-circuits to WriteJSON when both filters are
empty (skip the marshal-buffer round-trip for the common case).

Final review pass:
- Fix wire-contract bug: `--json id,name` (space form) is broken by
  pflag's NoOptDefVal; AGENTS.md / README.md / SetAgentHelp + the
  field-discovery help text all switched to `--json=id,name`.
- Fix `weknora api --jq` silently ignored: api.go now routes through
  WriteJSONFiltered with jopts.JQ.
- AGENTS.md: drop the false claim that `auth logout` honors `-y`
  (logout is local-only with no ConfirmDestructive guard); list the
  actual destructive commands instead.
- Rewrite cli/acceptance/e2e/e2e_test.go for the bare-data wire shape
  (was still parsing `out["data"]` / `env["ok"]`).
- Add `JSONOptions.Emit(w, v)` helper; collapse ~33 repeated
  `format.WriteJSONFiltered(iostreams.IO.Out, X, jopts.Fields,
  jopts.JQ)` sites to `jopts.Emit(iostreams.IO.Out, X)` — drops the
  format import from 22 cmd/* files.
- Delete single-caller `cmdutil.MustRequireFlag`; inline as
  `_ = cmd.MarkFlagRequired(...)` everywhere.
- Add `_ = cmd.MarkFlagRequired("name")` to `kb create`; it was the
  only write command relying on runtime --name validation while
  `context add` already used the cobra-level mark.
- `context use`: register `--json` / `--jq` (was always emitting JSON
  unconditionally with no human path and no flag — diverged from
  every other write command); human mode now prints
  `✓ Switched context to X (was Y)`.
- Replace per-package `confirmPrompter` / `scriptedConfirm` /
  `errPrompter` test doubles with `testutil.ConfirmPrompter`.
- Rename `chatService` → `ChatService` (export to match siblings
  `ListService` / `ViewService`); rename `printUploadSuccess` →
  `renderUploadSuccess` (siblings use `render*`).
- `defaultHint(CodeResourceNotFound)`: drop the hardcoded
  "list available with `weknora kb list`" — misleading on agent /
  doc / session 404. Replaced with "verify the resource ID and try
  again".
- Strip stale `v0.2/v0.3` / "envelope" / "v0.0/v0.1 supports only"
  historical tags from production comments and a few test
  descriptions.

nullkey 1b20b06f5e feat(cli): --json field-select, --jq, auth token, doc --from-url
Output ergonomics:
- `--json` accepts a comma-separated field list (gh-parity); selects
  named keys from the per-command payload. Bare `--json` keeps the
  full shape.
- `--jq <expr>` evaluates a gojq expression over the JSON; pairs with
  `--json field-list` so projection runs before jq.
- `--version` is a global cobra flag in addition to the `version`
  subcommand; both render the same line.
- Per-command `--help` now renders the available JSON field list under
  "JSON fields available via `--json id,name,...`" (field-discovery
  parity with gh / kubectl `-o jsonpath`).

New commands:
- `auth token` — print the active context's credential to stdout for
  shell command substitution (`WEKNORA_TOKEN=$(weknora auth token)`).
  Default: raw secret, no trailing newline. `--json` emits
  `{token, mode, context}`.
- `doc upload --from-url <URL>` — ingest a remote URL via the SDK
  `CreateKnowledgeFromURL`. `--name` forwarded as `FileName` so the
  server's known-extension heuristic upgrades crawl-mode to
  file-download-mode where appropriate.

Includes the simplify post-review polish pass (field-filter unit
tests, --json/--jq compose check, agent_help copy fixes).

nullkey 4c26bc9ecc feat(cli): auth refresh + transparent 401 retry transport
Two halves of v0.3 roadmap item 3-2.

(1) `weknora auth refresh` — explicit token renewal:
Reads the stored refresh_token, spends it via POST /api/v1/auth/refresh
(OAuth refresh-token grant), and persists both new tokens. API-key
contexts rejected with input.invalid_argument (no refresh semantic).

NOTE: gh CLI has `gh auth refresh` but with different semantics —
gh's variant is an OAuth scope expansion / re-prompt via the browser
(verified against the gh manual). The two share a name but solve
different problems; there's no direct gh parallel for refresh-token
grant because gh's PAT/OAuth-app model doesn't expose a short-lived
access_token + refresh_token pair to clients.

Error mapping:
- no current context → auth.unauthenticated
- --name unknown → local.context_not_found
- missing refresh in keyring → auth.token_expired (hint: re-login)
- server Success=false → auth.token_expired
- network → network.error
Envelope omits the token values (would leak into agent transcripts).

(2) AuthRetryTransport — transparent retry:
Wraps the SDK http.Client. On a 401 from a non-/auth/* endpoint:
- JWT context: read refresh token, hit /auth/refresh, persist new pair,
  replay original request with new bearer.
- API-key context: pass through (no refresh semantic).
- Non-replayable body (req.GetBody == nil): pass through.
- /auth/login or /auth/refresh: pass through (no recursion).
Concurrent 401s are singleflight-coalesced via sync.Mutex — 5 parallel
calls trigger exactly 1 refresh.

SDK additions (additive, non-breaking):
- WithTransport(rt http.RoundTripper) ClientOption.
- PathAuthLogin / PathAuthRefresh constants (cli/internal/cmdutil/authretry
  imports them so the CLI and SDK can't drift on path strings).

Refactor surfaced by the post-commit reviewer round:
- cmdutil.RefreshAndPersist(ctx, store, refresher, ctxName) — the
  load-refresh → call-SDK → persist-pair sequence was duplicated between
  the standalone `auth refresh` and the transport's refresh closure;
  collapsed to one canonical implementation.
- refreshFn signature takes context.Context so Ctrl+C during a
  transparent refresh cancels.
- AuthRetryTransport.CurrentToken() removed — never called.

8 + 8 + 8 unit tests cover happy path / refresh-fail / auth-endpoint
skip / api-key passthrough / singleflight under concurrency / non-
replayable-body fallback.

Roadmap: 3-2.

nullkey ca90ce422f feat(cli): add auth logout and auth list commands
gh / lark / gcloud / stripe all ship a logout command and a way to
enumerate stored credentials on day one. WeKnora's `auth` subtree had
only login + status, leaving no documented purge path for keyring
secrets — a real concern for `--with-token` (sk-…) and JWT flows that
write credentials to OS keychains.

auth logout [--name <ctx>] [--all] [--json]
  Clears keyring + file-fallback secrets (access / refresh / api_key
  slots) for the named context (default: current) or every context
  with --all. Removes the context entry from ~/.config/weknora/config.yaml
  and clears current_context if the removed entry was active.

  Mirrors `gh auth logout` and `lark auth logout`. As gh documents,
  this does NOT revoke server-side — for API keys users must rotate in
  the server UI, JWTs continue to be accepted until expiry.

auth list [--json]
  Renders a compact table (NAME / HOST / USER / MODE) with the active
  context marked `*`. Reads only config.yaml — no network, no keyring
  touch. Mode is inferred from which credential ref is set (api_key
  → "api-key", token → "password"; both → "password" wins).

  Mirrors gh's per-host enumeration (gh auth status iterates accounts)
  and lark `auth list`. For weknora the contexts file already had this
  data — the command is a thin renderer to match user muscle memory.

Deferred to a follow-up release:
  - auth refresh + transparent 401 retry in the SDK (we already persist
    refresh_token at login but never spend it; explicit gap)
  - login --web browser OAuth flow (requires a server-side endpoint)
  - auth token printer (cheap; defer with the rest)

Tests: 24 cli packages green. New: cmd/auth/logout_test.go (current
context, named, --all, no-contexts, unknown-name, no-current-no-flag,
mutex flags) + cmd/auth/list_test.go (human render, empty, JSON
envelope, inferMode edge cases). AGENTS.md command-surface note adds
the four-command auth subtree; screenshot section 4 adds `auth list`
alongside `auth status`.
2026-05-12 13:20:42 +08:00
nullkey 811802485e feat(cli): auth login + auth status commands (PR-4)
First two leaf commands and the auth/ command group, registered under
the root command tree.

auth login:
- Email + password (interactive huh prompter) OR --with-token (read API
  key from stdin) for headless / CI use
- Validates --host (required, must be http/https URL)
- Persists access + refresh tokens (password mode) or api_key (token mode)
  into the secrets store wired in PR-3 — uses Store.Ref to record the
  URI scheme without leaking concrete backend type
- Writes the named context to ~/.config/weknora/config.yaml and sets it
  as current_context
- Typed loginResult payload for --json output (no map[string]any)

auth status:
- Calls client.GetCurrentUser -> /auth/me, prints context / host / user /
  tenant. --json emits a typed statusResult envelope with _meta.context
  and tenant_id populated for agents.
- Service interface narrowed to just GetCurrentUser; tests inject fakes
  by overriding Factory.Client (no runF gymnastics).

cmd/root.go: register \`auth\` parent under the root tree.
