Initialize Target Platform

Overview

This skill authors a new target-platform profile YAML — the write-side of the contract in ../../context/target-platform-contract.md. It uses ../../references/bsp-platforms-catalogue.md as the canonical product / flash-config catalogue and ../../references/platform_template.yaml as the field schema.

Flow is linear: pick a reference product + flash config, then optionally add custom-carrier details. The two contract cases — reference-only vs reference + custom carrier — are distinguished only by whether the user provides custom-carrier details; there is no up-front mode prompt.

Scope is reference_devkit: and custom_carrier: only. Sibling skills own the other blocks: bsp_image: → jetson-init-image; source: → jetson-init-source; documents: → jetson-link-docs.

Outputs: a new target-platform/<name>.yaml and (by default) an updated active_target.yml pointing at it. To switch among already-authored profiles, use sibling jetson-set-target.

When to invoke

• The user asks to create / author / add a new target platform profile.
• A downstream skill refused with "no active target" and target-platform/ contains no profile YAML files yet (otherwise prefer jetson-set-target).
• The user wants a target whose profile does not yet exist on disk.

Procedure

Quick-start prefill mapping

Follow the shared quick_start_prefill contract. This skill consumes:

• quick_start_prefill.target.active_platform as the selected catalogue row when it resolves to exactly one product.
• quick_start_prefill.target.custom_carrier as the custom-carrier intent.

If active_platform resolves to one catalogue row, use it directly. Do not re-ask reference-product or flash-config questions; use the row's default flash config unless the prefill names a catalogue variant. Ask only when the prefill is missing, invalid, ambiguous, or names an unknown variant.

How the skill consumes the template

Load ../../references/platform_template.yaml once at skill startup and treat it as the schema for prompted blocks. Each placeholder value carries one of three sentinel markers:

| Marker | Behavior | |---|---| | <REQUIRED: description> | Prompt the user. Value must be provided; NA is accepted with a warning that downstream skills may refuse. | | <OPTIONAL: description> | Prompt the user. Value may be skipped (Enter or NA); skipped fields are omitted from the written profile (no empty key, no NA placeholder). | | <DERIVED: description> | Filled programmatically from bsp-platforms-catalogue.md and the user's product / flash-config choice in the "Pick the reference product" and "Pick the flash config" steps. Not prompted. |

Use the marker description as the prompt text verbatim. Match markers with the regex ^<(REQUIRED|OPTIONAL|DERIVED):\s*(.*)>$ after YAML parsing strips the surrounding quotes.

Block-level inclusion (custom_carrier) is decided by the skill flow, not by markers — adding/removing fields inside a block is a template-only change.

Survey current state

1. If target-platform/ does not exist, create it and copy ../../references/active_target_template.yaml to target-platform/active_target.yml (note .yml extension).
2. Read target-platform/active_target.yml.
3. List target-platform/*.yaml (excluding active_target.yml).

| Situation | Action | |---|---| | No profile YAMLs exist | Proceed — this is the bootstrap case. The new profile will be set as active_target automatically in the "Write" step (no activation prompt in the "Confirm" step). | | Profiles exist, active: NA | Show the list of existing profiles and confirm the user wants to author a new one (rather than activate one of the existing profiles via jetson-set-target). | | Profiles exist, active: names a present file | Show the active profile and the full list. Ask whether the user wants to (a) author a new profile alongside, or (b) switch to one of the existing profiles via jetson-set-target. If (b), stop and tell the user to run jetson-set-target. | | active: names a missing file | Tell the user the pointer is broken; offer to author a new profile (and replace the pointer) or to fix the pointer manually. |

Read the platforms catalogue

Read ../../references/bsp-platforms-catalogue.md. Parse the "Product / Chip / SKU / Flash Config Mapping" table — that is the source of truth for product names, CVM/CVB SKUs, default flash confs, and variant suffixes. Do not scan Linux_for_Tegra/*.conf or parse conf filenames; the catalogue already collapses that.

Pick the reference product (baseline)

Print the full catalogue list before asking. Group rows by chip family and number every entry with stable indexes for this run. Build the list only from bsp-platforms-catalogue.md; do not copy platform rows from examples or other docs.

Build explicit shortcut choices from the printed list by taking the first row in each chip-family group. Each shortcut label must include the full-list index and product name, for example Index 1 — Jetson AGX Orin 64GB. Do not hard-code product names; derive shortcuts from the parsed catalogue rows. These shortcuts are the only explicit choices for this question. Manual index entry must use the tool's built-in Type something input; do not add a third custom choice for manual entry.

Prompt text:

Pick a platform shortcut, or choose Type something and type the numeric index from the full platform list printed above. If your hardware is a custom carrier with one of these Jetson modules, pick the closest matching reference devkit as the baseline. Type cancel to cancel this run.

Do not show chip-family choices such as T234 / Orin family or T264 / Thor family. Do not show Type index, Manual entry, Other platform, or any custom manual-entry choice. The only manual-entry path is the tool-provided Type something row. Do not add Other as a choice or paraphrase Type something as Other in prompt text. Do not accept product-name substring matches in this step; typed input must be a numeric index from the printed full list or cancel. skip is not allowed because this skill cannot author a target profile without a reference platform.

Resolve the shortcut or typed index to exactly one catalogue row. If the typed index is out of range or invalid, show the valid index range and ask again. If the user types skip, explain that jetson-init-target requires a reference platform and ask again. If the user types cancel, stop without writing a profile.

Pick the flash config

From the catalogue row, the Default flash conf is option 1; the Variants column lists suffixes — option 2..N. Reconstruct each variant's full conf filename by appending the suffix to the default conf base. If a row says (same as <other>) in the Variants column, reuse the referenced row's variant list verbatim. Build this list only from the selected catalogue row.

Prompt:

Pick a number, or press Enter to accept the default (1).

If the chosen row has no variants (— in the catalogue), proceed to the "Optional: add custom carrier details" step with the default conf.

Edge cases:

• Raw-conf variants (catalogue marks (raw)). For Orin Nano, -a0-maxn (raw) → p3768-0000-p3767-0000-a0-maxn.conf. Use the raw filename verbatim.
• (same as <other>) placeholders. Reuse the referenced row's variants verbatim.

Optional: add custom carrier details

After the baseline + flash config are chosen, resolve whether the profile should record a custom carrier on top. If quick_start_prefill.target.custom_carrier is a valid concrete intent, consume it directly:

• add_custom_carrier → record custom_carrier: and collect the missing carrier metadata below.
• no_custom_carrier → omit custom_carrier: and proceed to the "Confirm" step.
• keep_existing_custom_carrier is valid only when editing an existing active profile that already has custom_carrier:. Because this skill authors a new profile, treat it as ambiguous and ask the custom-carrier intent question below.
• skip or a missing prefill value → ask the custom-carrier intent question below.

When intent is not already concrete, ask the user whether they also want to record a custom carrier on top using the AskUserQuestions UI. This is a bounded choice; show add and skip only:

Optionally add custom-carrier details for a customer-designed carrier using this Jetson module? (add / skip, default skip)

If the resolved intent is skip, proceed to the "Confirm" step with the custom_carrier: block omitted.

If the resolved intent is add, collect every still-missing custom_carrier: value through the AskUserQuestions UI. Do not collect custom-carrier metadata with plain-text prompts, inline chat questions, freeform summary confirmation, inferred defaults, or example values presented as selectable options. Split the collection into multiple AskUserQuestions forms if the UI question limit would otherwise be exceeded.

For the first AskUserQuestions form, ask custom_carrier.name, custom_carrier.id, custom_carrier.sku, and custom_carrier.revision in template document order. For these four fields, the only selectable path shown to the user must be the tool's built-in Type something row. Do not add example values, "Other", guessed board IDs, guessed SKUs, common revision strings, or any explicit domain options. These are customer-provided metadata: preserve them exactly as entered and do not require or validate any naming convention, prefix, case, character set, digit count, or SKU format. Validate only that required fields are non-empty unless the user explicitly enters NA. NA is accepted per the contract for required fields; warn that downstream skills may refuse if a missing field is required for their edit.

After custom_carrier.name is known, collect custom_carrier.flash_config through a second AskUserQuestions form if it is still missing. Show the suggested default as the only explicit choice and allow the built-in Type something row for a custom .conf filename. Require a non-empty filename ending in .conf; do not derive it from board ID, SKU, or any guessed convention.

Field-specific behavior (defaults / suggestions not expressible via markers alone):

• custom_carrier.flash_config — suggest a default of kebab-cased custom_carrier.name + ".conf" (e.g. "Acme Vision X1" → acme-vision-x1.conf).
• custom_carrier.name — prompt: "Type the customer-facing custom carrier or product name exactly as you want it recorded. No format is required." Use Type something only.
• custom_carrier.id — prompt: "Type the custom carrier board ID or project ID exactly as you want it recorded. No format is required." Use Type something only.
• custom_carrier.sku — prompt: "Type the custom carrier SKU or variant identifier exactly as you want it recorded. No format is required." Use Type something only; quote in the written YAML so num
