+**Agreed naming and aliases:** use `--llm-` canonical names throughout the
+reusable request-control family. Standard `promptkit` commands also accept the
+unprefixed convenience spellings wherever the corresponding flag applies.
+Application-owned commands receive canonical names from the reusable collections;
+applications may deliberately install convenience aliases on their own commands.
+
+| Canonical flag | Convenience alias within applicable `promptkit` commands |
+| --- | --- |
+| `--llm-endpoint` | `--endpoint` |
+| `--llm-model` | `--model` |
+| `--llm-temperature` | `--temperature` |
+| `--llm-max-tokens` | `--max-tokens` |

+| `--llm-var` | `--var` |
+| `--llm-input` | `--input` |
+
+Retain existing value syntax and units, including integer timeout seconds and
+file-backed input bindings. Commands taking a positional prompt ID retain that
+argument; this naming decision does not add a redundant prompt flag. Execution,
+resource-selection, and request-input collections may remain separately
+composable. Namespace controls remain subject to OD-3.
+
+**Agreed assembly approach:** keep alias generation in `ckprompt`; no core
+upgrade is required. Define each flag-to-alias relationship once and generate
+existing `FlagAliasFor` routing declarations from the flags selected for each
+enabled canonical command. Do not maintain a separate hand-written matrix of
+all command/flag combinations. Aliases target the original flag binding rather
+than introducing duplicate bindings. Both spellings retain core parsing,
+presence, and occurrence-order behavior.
+
+Offer a convenient collection containing the command family and its scoped
+routing declarations, using existing `[]commandkit.Declaration` installation.
+Keep `ckprompt.Command(suite)` available for canonical commands without the
+convenience aliases. Exact helper names remain implementation choices. Generate
+aliases only for enabled commands and applicable flags; do not install
+application-wide aliases or make consumers reproduce the command/flag matrix.
+Applications can install selected aliases on their own commands through the
+existing core API. Subtree alias scopes and a new core declaration-bundle type
+are not part of this adoption.
+
+Help should identify canonical names and their applicable aliases using current
+core presentation. Review published flag contracts during implementation and
+document migration, including retention of existing unprefixed spellings through
+the convenience collection. Do not assume canonical-only installation preserves
+those spellings.
+
+**Remaining request surface:** discuss output-contract overrides, inline-input
+flags, and appended-message flags individually before selecting scope and syntax.
+Agreement to discuss these separately does not yet include or defer them.
+Existing file inputs and application builders continue to support preview. A
+whole-output-contract file option and additional message/input options could
+support more reproduction workflows, with corresponding syntax, precedence,
+and reporting decisions. No general-purpose request-building API follows from
+these CLI choices.
