Add two single-page slide shortcuts on top of the raw
xml_presentation.slide create/delete APIs.
slides +add-slide appends or inserts one page into an existing
presentation. It accepts --presentation as a token, a /slides/ URL or a
/wiki/ URL (resolved via wiki.spaces.get_node and checked for
obj_type=slides), takes the page XML through --slide as a literal, @file
or stdin so the document never has to be escaped into JSON and then into
the shell, and auto-uploads <img src="@./local.png"> placeholders,
replacing them with the returned file_token. Omitting --before-slide-id
appends to the end; the field is dropped from the body rather than sent
empty, which the backend rejects as an unknown slide.
slides +delete-slide removes one page by slide_id with the same
--presentation resolution. It is deliberately Risk "write" rather than
the raw command's high-risk-write, so it does not require --yes: it
targets a single explicit page and the deck keeps its version history.
Both take one page at a time so that batching stays an explicit loop and
every call has an unambiguous outcome.
The image placeholder validation used by +create is extracted into a
shared helper so both commands fail before any API call when a referenced
file is missing, is not a regular file or exceeds the 20 MB upload limit.
Covered by unit tests and by dry-run e2e tests through the built binary,
which is the only layer that proves a full <slide> document survives flag
parsing intact. Reference docs are added for both commands and the
existing slides skill docs now route to them.
Emit structured validation, API, network, file, and internal error envelopes for Slides shortcuts so users and agents can recover from failed presentation workflows using stable type, subtype, param, and code fields.
Add Slides domain errscontract and golangci guards to prevent legacy envelope and common helper regressions.
Introduces `lark-cli slides +replace-slide`, a shortcut over the
native `xml_presentation.slide.replace` API for element-level editing
of existing Lark Slides pages. Callers pass a JSON array of parts and
the CLI handles URL resolution, XML hygiene, client-side validation,
and 3350001 hint enrichment.
Why a dedicated shortcut
The native API has three sharp edges every caller hits:
1. URL formats. Users have /slides/<token> or /wiki/<token> URLs, not
bare xml_presentation_id.
2. Undocumented XML hygiene. `block_replace` requires id=<block_id> on
the replacement root; <shape> requires <content/>. Missing either
returns a catch-all 3350001 with no guidance.
3. 3350001 is a catch-all on the backend with no actionable message.
Code
shortcuts/slides/slides_replace_slide.go (new)
- Flags: --presentation (bare token | /slides/ URL | /wiki/ URL),
--slide-id, --parts (JSON array, max 200), --revision-id (-1 for
current, specific number for optimistic locking), --tid,
--as user|bot.
- Validation (pre-API): [1,200] item cap; action restricted to
block_replace / block_insert (str_replace rejected); per-action
required fields (block_id for block_replace, insertion for
block_insert); per-field string type-assertion guards on the
decoded JSON so a numeric/bool payload fails fast with a targeted
error.
- XML hygiene:
* injects id="<block_id>" on block_replace replacement roots;
* auto-expands self-closing <shape/> and injects <content/> on
shapes for SML 2.0 compliance.
Dry-run surfaces injection errors and renders the same
path-encoded presentationID that Execute sends.
- On backend 3350001 attaches a generic common-causes checklist
(missing block_id / invalid XML / coords out of 960×540).
shortcuts/slides/helpers.go
- ensureXMLRootID: regex tightened to `(?:^|\s)id` so data-id and
xml:id are not matched as root id.
- ensureShapeHasContent: regex `<content(?:\s|/|>)` avoids false
positives like <contention/>; self-closing branch preserves
trailing siblings.
shortcuts/slides/shortcuts.go: register SlidesReplaceSlide.
Tests (package coverage 89.4%; parseReplaceParts and
injectBlockReplaceIDs both reach 100%)
- helpers_test.go: regex edge cases, id override semantics, content
auto-inject across self-closing and open-tag shapes.
- slides_replace_slide_test.go: parameter validation table, URL
resolution (slides / wiki), mixed block_replace + block_insert,
size boundaries, auto-inject behavior, 3350001 hint enrichment,
per-field type-assertion guards, whitespace-only --parts guard
(distinct from the `[]` "at least 1 item" path), replacement
without root element surfaces pre-flight instead of reaching the
backend, and a tight negative assertion that non-3350001 errors
get no slides-specific hint.
Docs (skills/lark-slides)
- SKILL.md: add +replace-slide to the Shortcuts table, register the
new xml_presentation.slide.get / .replace native endpoints,
update core rule 7 to prefer block-level replace over full-page
rebuild now that element-level editing exists, extend the error
table with 3350001 / 3350002 pointing at the replace-slide doc,
add "add image to existing slide via block_insert" as an explicit
Workflow step and symptom-table entry, and refresh the reference
index to include the three new docs below. The old "整页替换" 4-rule
checklist is retired — its one still-relevant guard (new <img>
avoiding overlap) is preserved in the symptom table.
- New references:
* lark-slides-replace-slide.md — flags, parts schema, auto-inject
notes, mixed-action support, 200-item cap, revision_id
semantics, error table, and a "合法根元素速查" cheatsheet for
the eight supported root elements (shape / line / polyline /
img / icon / table / td / chart) with minimal verified XML
snippets. Explicit unsupported list: video / audio / whiteboard
(these appear only as <undefined> export placeholders in SML 2.0).
* lark-slides-edit-workflows.md — recipe-style edit flows covering
the read → modify → write loop and the block_replace vs
block_insert decision tree.
* lark-slides-xml-presentation-slide-get.md — native read API with
block_id extraction examples.
- Fixes across existing references:
* replace / create / delete / presentations.get: add the .data
wrapper in return-value examples, correct jq paths.
* media-upload: fix jq path .file_token → .data.file_token.
* examples.md: annotate auto-inject behavior, replace the
incorrect failed_part_index example with the actual 3350001
error shape.
Empirical corrections (BOE-verified)
- revision_id: stale-but-existing values are accepted; only values
greater than current return 3350002.
- Wrong block_id returns 3350001, not a 200 with failed_part_index.
- Mixed block_replace + block_insert in one call is supported.
- Type-mismatched block_replace (e.g. shape id with a <td>
replacement) is silently accepted by the backend and may destroy
content; 3350001 specifically signals a missing block_id.
- New `slides +media-upload` shortcut: upload a local image to a slides
presentation and return the file_token for use in <img src="...">.
- `slides +create --slides` now supports `@./path.png` placeholders that
are auto-uploaded and replaced with file_tokens.
- Reject images >20 MB (multipart upload not supported for slide_file).
- Support wiki URL resolution for --presentation flag.
