# Markdown Image Alt-Text Writer

Analyze images referenced by Markdown and write concise, context-aware accessibility alt text.

## Required Aident Actions

- <action-tag>direct:fal:fal_analyze_media</action-tag> (required inputs: inspect the current schema): Run an active Fal image and video understanding model. Defaults to fal-ai/florence-2-large/more-detailed-caption. Call fal_list_media_analysis_models before selecting another model to inspect current pricing,...

Use Aident Loadout to read the current Action schema before constructing inputs. Check the required integration connection in Aident Vault. If an Action is billable or mutating, run Aident preflight, show the affected target and quoted cost or risk, and wait for explicit user confirmation before execution.

## Workflow

1. Confirm the requested outcome, source material, destination, audience, constraints, and acceptance criteria.
2. Apply the source-derived guidance below to create a concrete plan. Resolve ambiguity before invoking an Action.
3. Select only the Aident Actions whose documented effect directly advances the requested outcome. Do not invoke every listed Action by default.
4. Inspect the current schema and prepare the minimum valid input for each selected Action.
5. Preflight each selected Action. Execute it only after any required confirmation, in dependency order, and carry returned IDs or asset URLs into later steps.
6. Verify the returned IDs, URLs, statuses, or artifacts against the acceptance criteria. Report partial completion precisely and do not repeat paid or mutating calls blindly.

## Source-Derived Guidance

- Collect each image asset together with its surrounding Markdown heading, paragraph, link destination, and intended audience.
- Use direct:fal:fal_analyze_media on each non-decorative image to identify only visible subjects, text, relationships, and function relevant to the surrounding content.
- Write concise alt text that conveys the image's purpose in context; use an empty alt value for decorative images and avoid phrases such as image of.
- Do not invent names, metrics, chart values, or unreadable text. Flag uncertain details and return the proposed Markdown image syntax without claiming that a source file was modified.

## Execution Boundaries

- Treat upstream provider-specific commands as background knowledge only. Execute the workflow through the exact Aident Actions above.
- Never request raw credentials in chat. Use Aident Vault connection flows for required accounts.
- Preserve user-provided wording, brand constraints, rights restrictions, and target identifiers. Do not invent authorization.
- Pass assets by Aident asset ID or supported URL fields. Do not expose caller-local filesystem paths to hosted Actions.
- Stop when a required integration is disconnected, preflight rejects the input, the target is ambiguous, or the user declines a required confirmation.

## Output

Return the execution plan, selected Action names, confirmed targets, Aident result identifiers or asset URLs, verification evidence, and any remaining blocked step.
