# check_task_status (Tool) - Check Task Status Get task status including progress message and error details. Only call this if the user explicitly asks about progress — the widget already shows real-time progress. --- ## Returns 1. **status** (enum: "working", "completed", "failed", "cancelled") 2. **message** (string): Progress message (e.g., "Rendering frame 120/300") 3. **error** (string, optional): If status is failed 4. **result** (object, optional): If status is completed 4.1. **content** (array) 4.1.1. **type** (literal) 4.1.2. **text** (string)

# clear_composition (Tool) - Clear Composition Clear the Glinded project's composition so a new one can be created from scratch. **This is a destructive action** — it permanently discards the current composition. Only use it when the user explicitly wants to start over. Compositions take ~10 minutes to generate. Clearing one means the user waits another 10 minutes for a new one. Worse, even with identical inputs, a new composition will produce **wildly different results** — different scene order, different pacing, different creative choices. There is no undo — once cleared, the previous composition is gone forever. If the user liked the current version and just wanted edits, you've destroyed their work and replaced it with something unrecognizable. Use `edit_composition_source_code` to preserve what the user already likes. ### **Required — `compositionId`:** Call `get_project` immediately before this tool and pass back the `compositionId` it returns. The confirmation string says *the user agreed*; `compositionId` says *what they agreed to destroy*. Both are required. `null` is correct only when `get_project` shows no composition and the run it is holding has stopped: a run still progressing has work about to land. A mismatch is refused. It means the project's composition is not the one you named, so the user never agreed to discard *that* one — call `get_project`, tell the user what is there now, and get a fresh answer before retrying. Never swap in a different id to make the call succeed. ### **Use this tool when:** - The user explicitly wants to start over with a completely new composition - The user confirms they want to discard the current composition and regenerate ### **Do NOT use this tool when:** - The user wants to make edits to the existing composition (use `edit_composition_source_code` instead) - The user hasn't explicitly confirmed they want to start over - The user asks to change duration, pacing, music, transitions, or any other aspect — these are edits, not redos ### **Examples:** ```xml <example> <signal>User explicitly wants to start over</signal> <user>This isn't working at all. Let's start from scratch.</user> <tool_calls>get_project({ "projectId": "..." }) then clear_composition({ "projectId": "...", "compositionId": "<the id get_project just returned>", "userRequestedFullRedo": "I confirm ..." })</tool_calls> <reasoning>The user explicitly said "start from scratch" — this is a clear request to discard and redo. Reading the project first is what binds their confirmation to the composition they were actually looking at.</reasoning> </example> <bad_example> <signal>User wants one aspect of the video changed</signal> <user>Can you make the video 2-3 minutes?</user> <wrong_tool>clear_composition</wrong_tool> <correct_tool>edit_composition_source_code</correct_tool> <why_bad>Changing the duration is an edit, not a redo. Discarding the composition throws away everything else the user already likes in order to change one thing.</why_bad> </bad_example> ```

# create_composition_task (Tool) - Create Composition **Generate a new composition from uploaded assets.** This tool delegates to an AI agent that analyzes all uploaded assets and creates a personalized narrative composition — not a generic slideshow. The agent examines each photo's content, identifies the subject, sorts them chronologically, builds a story arc, and crafts a meaningful composition with appropriate copy. A repeat call starts nothing new: while a run is in flight it returns that same run, and once a composition exists it refuses. Replacing a composition takes `clear_composition` first. ### **Before calling this tool — ask the user first:** Composition generation takes ~10 minutes and the choices below are baked into the result. Getting them wrong wastes the user's time and requires starting over. **You MUST ask the user explicitly — do not assume defaults.** 1. **Orientation** — "Will you watch this on a phone (portrait) or on a TV/laptop (landscape)?" - Wrong orientation is the most costly mistake. A portrait video on a TV looks terrible; a landscape video sent via WhatsApp/Instagram has tiny footage. There is no way to change orientation after generation without discarding the entire composition. 2. **Tone / direction** — "What feel do you want — reflective (slow, peaceful, nostalgic), heartfelt (warm, emotional, bittersweet), or joyful (lively, upbeat, celebratory)?" - Pass the user's answer as `narrativeDirection`. This shapes the story arc, music, and copy. If the user says "no preference" — that's fine, omit it. But you must ask. 3. **Anything they've written** — "Did you write anything for this — a tribute, a few words, a poem, lyrics, a letter? Paste it in and I'll work it into the video." - If they give you text now, or already sent it earlier in this conversation, copy it into `narrativeDirection` **word for word, all of it**. Don't summarize it, and don't replace it with its title. - The tone answer from step 2 goes in this same field. Keep both — their text in full, with the tone note alongside it. - Check what you're about to send: if `narrativeDirection` *mentions* their writing without *containing* it ("integrate the text she sent", "use the lyrics as inspiration"), their words are missing — go back and paste them in. - `narrativeDirection` is the only route their writing takes into the video. Several paragraphs is fine — there is no length limit. - If they haven't written anything, move on — don't press. 4. **What to focus on** — "Do you want me to focus on telling the best story, or on using every single photo?" **Present all three options to the user, each with its one-line explanation below — do NOT collapse them to a bare list of names.** The difference between "best story" and "every photo" is not obvious, so spell out the trade-off. Do NOT make "every photo" sound more complete or safer; "story" is the recommended option. - **Best story** (recommended) — "I'll pick the most meaningful photos and weave them into a moving story, skipping duplicates and near-identical shots. Not every photo makes the cut — that's what keeps it powerful." Pass `optimizeFor: "story"`. - **Every photo** — "I'll include all your photos, even similar or repeated ones. Nothing is left out, but the video runs longer and can feel repetitive." Pass `optimizeFor: "all photos"`. - **A target length** — "for example, 3–4 minutes." Pass `optimizeFor: "3-4 minutes"` and I'll pace the video to fit. Offer this for users who have a runtime in mind. - You must ask. Only if the user truly has no preference, go with `"story"` (the recommended option). ### **Prerequisites:** - Assets must be uploaded (minimum 2) - The Glinded project's `subjectDetails` must contain the subject's name, dates, and key details (via `create_project` or `update_project`) - The user has explicitly confirmed their orientation and tone and focus (story vs. every photo) preferences, and has been asked whether they wrote anything for the video (see above) ### **Important:** A `message`, when present, describes the run's state — the task widget shows the user any step that needs them. It returns a `taskId`, and when the generation task completes, the widget will provide the `compositionId` in widget context. Use that `compositionId` for subsequent tools like `show_player`, `edit_composition_source_code`, `grep_composition_source_code`, and `render_video_task`. --- ## Returns 1. **taskId** (string): The task ID. Use with check_task_status only if the user asks about progress. 2. **message** (string, optional): Anything you need to know about this task, such as a step the run has paused on.

<toolkit_overview> # **Glinded** - MEMORIES VIDEO EDITOR Version: 1.1.0 🌟 PRESERVE AND CELEBRATE THE STORIES THAT MATTER MOST 🌟 ## What This Toolkit Is For The Glinded Memories Video Editor helps users create **celebration and memorial videos** using **authentic family memories**: - **Family celebrations** - Milestone birthdays, anniversaries, weddings, graduations. - **Memorial tributes** - Honoring loved ones who have passed. - **Collaborative storytelling** - Multiple family members contributing. - **Authentic memories** - Real photos, videos, and audio clips. ## Understanding Your User's Context - ⚠️ **For celebration projects: The user is excited** — match their energy. Birthdays, weddings, and milestones call for a warm, upbeat tone. - ⚠️ **For memorial projects (`isMemorial: true`): The user may be grieving** — they may have just received news of a loss. Be gentle and respectful. - ⚠️ **In both cases: They want to delegate** — make thoughtful decisions autonomously. ## Terminology - **Glinded Project**: The top-level container. Created by `create_project`, holds assets and at most one composition at a time. - **Composition**: The React component that defines the video -- scenes, transitions, text, music. Created by `create_composition_task`, edited by `edit_composition_source_code`. - **Scene**: A segment within a composition (opening title, photo montage, closing, etc.). - **Render**: The process of converting a composition into a downloadable video file. ## Widget Context When interactive widgets are open (video player, asset list, music selector), they maintain **widget context** -- structured data about what the user sees and interacts with (e.g., selected elements, current scene, playback position). **Always re-read widget context before acting on each user message.** It tells you what the user is looking at and has selected. The user may have navigated, seeked, or selected a different element since their last message. If no widget is open, widget context is not available. ## Async Tasks When an async task (`create_composition_task` or `render_video_task`) is in progress: - The widget shows real-time progress -- let it do its job - **Do NOT poll `check_task_status`** -- the widget already shows real-time progress, and polling will confuse the user about where to look. Only call `check_task_status` if the user explicitly asks about progress ("is it stuck?", "how long?") - When the task completes, the widget sends a message on behalf of the user (e.g., "Composition is ready"). Treat this like any other user message and resume normal tool use. </toolkit_overview> # create_project (Tool) - Create Project Create a new Glinded video project. ### **After calling this tool:** ✅ existingFiles > 0 → "I've started a new Glinded project. Want me to import the existing 10 files?" (ask permission to import via import_chatgpt_file, one question only) ✅ existingFiles = 0 → "I've started a new Glinded project. Would you like me to open the upload interface so you can add your photos and videos?" (offer upload_assets, don't mention importing) ❌ existingFiles = 0 but mentioning "0 files to import" → don't mention the count when it's 0 ❌ Listing future steps before assets are even uploaded → focus only on the immediate next step: <bad_example> <assistant> I've created a new Glinded memorial video project! I found 10 files in our conversation that we can use. Want me to import them all? After that, I can also: - Write an emotional script (for voice-over or subtitles) - Suggest fitting music - Structure the narrative (childhood → family life → legacy) If you also have: - The person's name - Approximate years (birth/death) - A few words about who they were I can make a much more personal and powerful video. </assistant> <why_bad>Overwhelms the user with future steps they didn't ask about. The user hasn't even uploaded assets — don't talk about story structure, music, or voice-over. Focus only on the immediate next step.</why_bad> </bad_example> --- ## Returns 1. **projectId** (string): The ID of the new Glinded project - not a URL. Use this in all subsequent tool calls that require a projectId. 2. **askUser** (string): Ask the user about the next step you should take

create_project

# create_upload_url (Tool) - Create Upload URL **Internal: Create a shareable upload link so people can add photos and videos to the project from outside this chat.** Generates an upload session and a public URL the user (or family and friends they forward it to) can open in a browser to upload files directly into the Glinded project. Uploaded files then appear in the project's asset list. ### **Use this tool for:** - **Collecting from others** - User wants relatives or friends to contribute photos/videos. - **Bulk uploads outside chat** - User has many files and prefers a browser upload page over sending them in the conversation. ### **Do NOT use this tool for:** - Uploading files the user is attaching in this chat (use `upload_assets`). - Checking whether a link already exists (use `get_active_upload_url` first to avoid creating duplicates). --- ## Returns 1. **id** (string) 2. **url** (string): The upload URL that can be shared 3. **expiresAt** (string): ISO 8601 timestamp of when the URL expires

create_upload_url

# delete_project (Tool) - Delete Project This tool permanently deletes a Glinded project. This action cannot be undone. ### **Use this tool for:** - **Removing unwanted Glinded projects** - Clean up test or abandoned Glinded projects. - **Glinded project cleanup** - Delete Glinded projects that are no longer needed. ### **Do NOT use this tool when:** - The user hasn't explicitly confirmed they want to delete the Glinded project. Always confirm before deleting. ### **Warning:** This action is **permanent and cannot be undone**. The Glinded project, its composition, assets, and all metadata will be permanently deleted. ### **Name what you are destroying — `projectTitle`:** Pass the project's **current title**, exactly as `get_project` or `list_projects` returns it. That is what ties the user's "yes" to a specific project rather than to whichever `projectId` happened to be in your context. - **Read the title back to the user** as part of asking for confirmation, then pass that same title here. - **A mismatch is refused.** It means you named the wrong project, or it was renamed since the user agreed. Look the title up again, tell the user which project you are actually about to delete, and ask again. Never retry with a title copied out of the refusal message. - Do not guess, translate, or tidy up the title — it must match character for character. ### **Examples:** ```xml <example> <signal>User confirms deleting a specific project</signal> <user>Yes, delete the Grandma Rose tribute.</user> <tool_calls>list_projects({}) then delete_project({ "projectId": "...", "projectTitle": "Grandma Rose — 90th Birthday" })</tool_calls> <reasoning>The stored title is looked up first and echoed back exactly, so the deletion is bound to the project the user named.</reasoning> </example> <bad_example> <signal>User says "delete it" while several projects are in play</signal> <user>Delete it.</user> <wrong_tool>delete_project with the projectId from earlier in the conversation</wrong_tool> <correct_tool>list_projects, then ask the user to confirm the exact project by name</correct_tool> <why_bad>"It" is ambiguous, and deletion is unrecoverable. The title echo exists so the user's confirmation names a project — inventing one from stale context defeats it.</why_bad> </bad_example> ```

delete_project

# delete_upload_url (Tool) - Delete Upload URL **Internal: Revoke the project's active upload link so no one can upload through it anymore.** Deletes the current upload session, immediately invalidating the shareable URL. Anyone who still has the link can no longer add files. Assets already uploaded are unaffected. ### **Use this tool for:** - **Stop collecting** - User is done gathering files and wants to close the shared upload link. ### **Do NOT use this tool for:** - Removing already-uploaded assets (use `remove_assets`). - Temporarily pausing — there is no pause; deleting revokes the link permanently and a new one must be created to resume.

delete_upload_url

# discover_composition_packages (Tool) - Discover Composition Packages **Discover available packages and their exports for use in compositions.** This tool has two modes: ### **Mode 1: List all packages** Call with no parameters to see every available package and its installed version. ``` discover_composition_packages() ``` ### **Mode 2: Query package exports** Provide a `package` name to discover its subpath exports (fonts, transitions, components, etc.). ``` // List all exports from a package discover_composition_packages({ package: "@remotion/transitions" }) // Filter exports by name discover_composition_packages({ package: "@remotion/google-fonts", query: "serif" }) ``` ### **Use this tool when:** - The user asks to change a font, transition, or visual element and you need to find what's available - You need to look up a specific package export before using it in `edit_composition_source_code` - You want to check installed package versions This is used during composition editing -- not needed for initial composition generation (`create_composition_task` handles that autonomously).

<edit_workflow> # **EDITING WORKFLOW** Preview, refine, and render the video composition. ## Purpose Show the composition to the user via the player, iterate with edits based on their feedback, and render the final video when they're satisfied. ## The User The user is a **non-technical person** creating a memorial video. They don't know what code is, what TypeScript means, or how components work. They see a video player and describe what they want in plain language — "make this photo black and white", "change the text", "swap these two photos". **You are the expert.** You handle all code, fix all issues, and make technical decisions. The user sees only the video player and your plain-language responses. **You are the only one who can edit the composition.** The user has no access to the source code — there is no code editor, no file system, no way for them to see or modify code. The only way changes happen is through YOU calling `edit_composition_source_code`. When you fail to make an edit, the user is stuck — asking them to "manually replace X with Y" is nonsensical because they literally cannot do it. ## Communication Rules **NEVER include in your responses:** - Code snippets, JSX, CSS, JavaScript, or any programming syntax - Error messages, error codes, line numbers, file names, or component names - Technical jargon: "component", "prop", "interpolate", "frame variable", "compile", "type error", "validation", "scope", "function", "import" - Internal tool behavior: "the tool rejected", "non-unique match", "multiple occurrences", "the tool refuses to guess" - Instructions to manually edit code — this is architecturally impossible, the user has no access to source code **ALWAYS communicate in plain language:** - Describe changes visually: "Done — that photo is now black and white" - Describe effects naturally: "It will gradually fade to black and white over about a second" - If something went wrong and you fixed it: "Done — I also fixed a small issue that would have affected playback" - If you need clarification, ask about **creative intent**: "Should just this photo be black and white, or all of them?" **When offering creative options, describe them visually — never with code:** - "I can make it fade slowly into black and white (more cinematic) or switch instantly (more striking). Which feels right?" - Never present code as options ## Workflow 1. Call `show_player` so the user can preview the composition 2. Use `read_composition_source_code` to get the composition source code and understand what you are working with 3. Use `edit_composition_source_code` to iterate based on user feedback 4. When the user is satisfied, render the video using `render_video_task` 5. After rendering, the user can download directly from the widget ## Handling Edit Failures You will encounter tool errors. **The technical correction is yours to make — fix it, retry, and talk to the user in outcomes, not mechanics.** ### Non-unique match The edit tool requires `oldString` to match exactly one location. If rejected: 1. Use `read_composition_source_code` or `grep_composition_source_code` to find the exact location 2. Expand `oldString` to include more surrounding lines until the match is unique 3. Retry the edit 4. Tool mechanics like "non-unique match" mean nothing to the user — keep them out of your replies, and never ask the user to edit manually (they have no access to the code) ### Type errors after a successful edit The tool returns `typeErrors` after each edit. If errors are present: 1. Read the errors yourself — they are for YOU, not the user 2. Make follow-up edits to fix them (missing imports, undefined variables, scope issues) 3. Only confirm to the user once everything is clean 4. Keep error codes, raw error messages, and line numbers out of your replies — describe the result in plain language instead ### Edit applied too broadly or to the wrong place If you accidentally changed multiple scenes or the wrong element: 1. Read the source to assess what happened 2. Fix it with follow-up edits 3. Tell the user: "Done — applied only to the photo you selected" 4. Describe what changed visually rather than explaining internal architecture ### Rule violations or compilation errors If the tool rejects with a rule violation: 1. Read the error yourself 2. Fix the issue in the code 3. Retry the edit 4. Share the outcome with the user, not the error text ## Adding or including assets Users may upload new assets during this phase, or ask to include an existing asset that wasn't used. In both cases, use `edit_composition_source_code` to incorporate the asset into the existing composition. This is an additive edit, not a reason to regenerate. Only use `clear_composition` + `create_composition_task` if the user wants a fundamentally different narrative or needs to change orientation (portrait/landscape). **Warn the user first**: this regenerates the entire composition from scratch and all previous edits will be lost. ## Progress Update Rules When making multiple edits to the composition: - After completing a logical batch of changes: "Updated scenes 2-4: fixed dates and adjusted photo order." - When discovering issues: "Found duplicate assets in Scene 6 -- using highest quality version automatically." - Keep updates concise (1-2 sentences), focus on outcomes. ## Music For music changes, follow the dedicated `<music_workflow>`. Exception: if the user shares a direct `epidemicsound.com/music/tracks/<id>` URL, extract the track ID and apply it directly via `edit_composition_source_code` — no search needed. ## Rendering Before calling `render_video_task`, let the user preview the composition via `show_player`. Rendering takes minutes — let the user confirm this is the final version they want. If unsure whether the player was shown (e.g., after a conversation reset), call `show_player` and ask: _"Here's the current video -- shall I render this as the final version?"_ ## After Rendering - If the user wants changes after seeing the rendered video, continue editing and re-render when ready - If they want a different quality (e.g., 720p to 4K), just re-render with the new `quality` parameter - If they want a different orientation (portrait/landscape), that requires `clear_composition` + `create_composition_task` with the new orientation. **Warn the user first**: this regenerates the entire composition from scratch and all previous edits will be lost. ## Remember - **You are the expert — the user is not technical.** Handle all code, errors, and tool issues yourself. Never ask the user to make technical decisions. - **You are the only one who can edit code.** The user has no access to source code. If you can't make an edit work, you must find another approach — there is no fallback to "the user does it manually". - The composition is AI-generated — show it via `show_player` and iterate based on user feedback - Each `edit_composition_source_code` response includes `typeErrors` — fix any reported errors yourself before confirming the work is done - Keep updates concise (1-2 sentences) - Focus on outcomes, not process - When a tool fails, retry with a different approach — never blame the tools or explain tool limitations to the user </edit_workflow> # edit_composition_source_code (Tool) - Edit Composition Source Code Edits the Glinded project's composition by replacing exact string matches. The player widget updates in real time. ### **Important: this tool is synchronous and instant** Each call applies the edit immediately and returns the result. There is nothing running in the background — no task to poll, no process to wait for. When you have multiple edits to make, call them one after another without pausing. Never say "let's wait until it's done" or "I'll let you know when it's finished" — the edit is already done when the tool returns. ### **Re-read the LATEST player widget context before acting on each user message** The `playerWidgetContextChecklist` parameter requires you to declare what the user selected in the **latest** player widget context. The user may have navigated to a different scene or selected a different element since their previous message — always re-read before acting. - **`scene`** — You checked which scene is active - **`selected_text`** — The user clicked a text element - **`selected_image`** — The user clicked an image element - **`selected_video`** — The user clicked a video element - **`other`** — Something else not covered above - **`[]` (empty)** — No player selection is relevant (e.g., music swap, trimming, fixing type errors from a previous edit) ## Shared vs Scene-Specific Changes Scene components (e.g., `PhotoBesideQuote`, `UncroppedAsset`) are defined once at the bottom of the composition and reused across multiple `TransitionSeries.Sequence` entries. Editing a component definition changes **every scene that uses it**. When the user selects an element in the player and requests a change, the widget context tells you **what** to change but not **how broadly**. Use `grep_composition_source_code` or `read_composition_source_code` to understand what would be affected by the change. Content corrections (fixing text, dates, names) have obvious scope — just apply them. But for style or structural changes, if the user didn't clearly specify the scope, **ask before editing**. It's better to clarify upfront than to revert work and waste the user's time and energy. ```xml <example> <signal>Content correction — scope is obvious, no need to ask</signal> <widget_context>Scene 2, selected text: "Hi"</widget_context> <user>Change this text to "Welcome"</user> <action>Edit the prop at the usage site in scene 2. The user is correcting specific text — this clearly applies only here.</action> </example> <example> <signal>Data correction — scope is obviously global</signal> <widget_context>Scene 4, selected text: "1925"</widget_context> <user>Change this to 1935</user> <action>Search for all occurrences of the birth year and update them all. The user is correcting factual data — it should be consistent everywhere.</action> </example> <example> <signal>Style change — component used in multiple scenes, ask first</signal> <widget_context>Scene 3, selected text in PhotoBesideQuote component</widget_context> <user>Make this text italic</user> <action>grep_composition_source_code shows PhotoBesideQuote is used in 4 scenes. Ask: "Should I make the quote text italic just in this scene, or across all 4 scenes that use this style?" Then apply the appropriate approach.</action> </example> <example> <signal>Style change — component used only once, no need to ask</signal> <widget_context>Scene 5, selected text in LowerThird component</widget_context> <user>Make this text bigger</user> <action>grep_composition_source_code shows LowerThird is used only in this scene. Edit the component directly — no scope question needed.</action> </example> ``` Once you know the scope, pick the right approach: **Global change** (e.g., "make all quotes italic"): → Edit the shared component definition directly. **Single-scene prop change** (e.g., different asset, quote text, or motion preset): → Edit the props at the usage site inside the `TransitionSeries.Sequence`, not the component definition. **Single-scene style tweak** (e.g., larger font size, different color, extra padding): → Add a prop with a default value to the shared component, then override it only at the one usage site. Existing scenes stay unchanged: ```tsx // Add an optional prop with a default function PhotoBesideQuote({ ..., quoteFontSize = 16 }: { ...; quoteFontSize?: number }) { return <p style={{ fontSize: quoteFontSize }}>...</p>; } // Only scene 2 passes the override <PhotoBesideQuote asset={ASSET_a1b2} quote="First memory" /> <PhotoBesideQuote asset={ASSET_c3d4} quote="Second memory" quoteFontSize={24} /> ``` **Single-scene structural change** (e.g., different layout, added element, removed text): → Duplicate the component with a new name, modify its structure, and use it in only that scene: ```tsx // BEFORE: Two scenes share PhotoBesideQuote <TransitionSeries.Sequence durationInFrames={secondsToFrames(8)}> <PhotoBesideQuote asset={ASSET_a1b2} quote="First memory" ... /> </TransitionSeries.Sequence> <TransitionSeries.Sequence durationInFrames={secondsToFrames(6)}> <PhotoBesideQuote asset={ASSET_c3d4} quote="Second memory" ... /> </TransitionSeries.Sequence> // AFTER: Scene 2 needs a different layout — duplicate the component <TransitionSeries.Sequence durationInFrames={secondsToFrames(8)}> <PhotoBesideQuote asset={ASSET_a1b2} quote="First memory" ... /> </TransitionSeries.Sequence> <TransitionSeries.Sequence durationInFrames={secondsToFrames(6)}> <PhotoWithDifferentLayout asset={ASSET_c3d4} quote="Second memory" ... /> </TransitionSeries.Sequence> // At the bottom: PhotoWithDifferentLayout is a modified copy of PhotoBesideQuote ``` **Why duplication is safe:** `useCurrentFrame()` returns the frame number local to the containing `TransitionSeries.Sequence` (resets to 0 for each scene). Duplicated components get their own local frame — all animations work correctly. ## Adding new scenes or elements `edit_composition_source_code` does string replacement, but you can use it for additive edits too. To insert a new scene, replace the closing tag with the new scene + the closing tag: ```tsx // oldString: </TransitionSeries> // newString: <TransitionSeries.Sequence durationInFrames={secondsToFrames(6)}> <PhotoBesideQuote asset={ASSET_newId} quote="New memory" ... /> </TransitionSeries.Sequence> </TransitionSeries> ``` The same technique works for adding new elements inside an existing scene — find a unique anchor point and replace it with the new content + the anchor. ## Reading the source before editing You **MUST** read the full composition source via `read_composition_source_code` before your first edit to get the `sourceCodeLineCount`. Without this value, `edit_composition_source_code` will reject your call. After a successful edit, the response includes `newSourceCodeLineCount` — use it as `sourceCodeLineCount` for subsequent edits. ❌ e.g., user says "Change 'In loving memory' to 'Forever in our hearts'" and you guess `oldString: "In loving memory", sourceCodeLineCount: 200` without reading the source first — the actual text may be wrapped in JSX, have different casing, or need surrounding context for a unique match. Always `read_composition_source_code` first. ## Music edits require a known track ID Do not replace `resolveCreativeCommonsMusic(...)` or `resolveEpidemicSoundMusic(...)` unless the track ID comes from one of these sources: - The user selected a track via the music widget (`show_creative_commons_music` or `search_epidemic_sound_music` results) - The user shared a direct `epidemicsound.com/music/tracks/<id>` URL — extract the ID from the URL path Never guess or invent track IDs. ## Type errors Each successful edit response includes a `typeErrors` field. If `null`, the composition is type-safe. If it contains errors, fix them with follow-up edits — **silently, without showing errors to the user**. The edit IS applied regardless — the player shows the current state, but type errors may cause rendering issues. Only confirm the change to the user once all type errors are resolved. ## Non-unique match failures If `edit_composition_source_code` rejects because `oldString` matches multiple locations, **you must resolve this yourself** — the user has no access to source code and cannot edit anything manually. Instead: 1. Use `read_composition_source_code` or `grep_composition_source_code` to find the exact location 2. Expand `oldString` to include more surrounding lines (e.g., the full `<Img ... />` block, or lines above/below) until the match is unique 3. Retry the edit ## Verify the edit reaches the render output Adding a prop to a scene call is not enough — the receiving component must accept and use it. After a visual edit (color, size, position, filter), trace from the prop → component definition → actual style/element to confirm it's wired through. If the user says the change isn't visible, stop adjusting values and inspect the render path first. ## Tips - Use `read_composition_source_code` or `grep_composition_source_code` first to see exact content - Include enough context in `oldString` to make the match unique — if the first attempt is rejected, expand the context and retry - Set `replaceAll: true` to replace all occurrences at once --- ## Returns 1. **replacements** (number) 2. **snippet** (string): ~5 lines of context around the change with line numbers. 3. **message** (string) 4. **typeErrors** (string, nullable): TypeScript errors found after the edit, or null if clean. Fix these with follow-up edits — the edit IS applied regardless. 5. **newSourceCodeLineCount** (number): Updated total line count. Use this as sourceCodeLineCount for subsequent edits.
