feat: support arguments in Custom Prompts #4040

icedac · 2025-09-22T10:17:05Z

What

Add support for passing arguments to custom prompts executed via slash commands and custom commands.
Expose the raw argument string to the template as the $ARGUMENTS (and $0...$9) placeholder so it can be rendered inside the .md file.
Use the frontmatter YAML property named 'description' to display descriptions in the slash popup.
Keep behavior fully backward-compatible when no arguments are provided.

Why

Users need to parameterize prompts to avoid duplicating similar .md files and to tailor executions dynamically (see Custom prompts - passing arguments #2890).

How

Thread the user-provided argument string from the slash/custom command invocation through the execution pipeline and expose it to the renderer as $ARGUMENTS, $0, $1 ... $9
Fallbacks:
- If the argument string is empty, nothing happens.
This also fixes custom prompts to work with history, making them usable (previously this was not working properly).

Prompt with Arguments

Description Showing in Slash Popup

Works as Expected!

Backward Compatibility

No breaking changes. Existing prompts without $ARGUMENTS continue to work unchanged.

Interested to know what's diff vs. #3565

I think almost same but have different view for that issue, OAI team let the history navigation doesn't works with it so they disabled history nav with custom promtps so I fixed it to works with this pr.

…TS, $0..$9) Implements token substitution when submitting a selected custom prompt via the slash popup. - Adds parsing of positional args from the composer first line. - Supports $ARGUMENTS (joined args), $0 (prompt name), and $1..$9 (positionals). - Leaves tokens intact when a referenced positional is missing. - Includes unit tests for joined, positional, and missing cases. Note: handling of history overrides and typed slash commands without popup are deferred to a later commit.

Core: parse minimal front matter and capture description (if present), stripping it from the body.\nProtocol: extend CustomPrompt with optional description.\nTUI: display prompt.description in the command popup (fallback to default when absent).\nTests: updated to include description: None for constructed prompts.

Composer: capture raw input when submitting a custom prompt, and set a one-shot history override. Also block history navigation for '/ ' contexts until prompts finish loading, and expand typed custom prompts even when the popup is not used. BottomPane: expose take_next_history_override for ChatWidget. ChatWidget: persist history using override text when present, keeping conversation text unchanged. fix: Substite $ARGUMENTS with all multiline inputs.

Is this a duplicate of PR #3164 ?

I think not exactly but have common to support $ARGUMENTS.

I think this issue has been around for 3 weeks, so there are more than 3 PRs for this one. I created this for my own use and to help get OAI working.

Hey guys, coming soon! @evandavid1's PR was merged into a feat branch, and I'll combine it with some named params and submit for a PR & review this week.

Originally posted by @dedrisian-oai in #2890 (comment)

Numbered args ($1, $2, $3, $ARGUMENTS) has been merged. Named args coming next!

Originally posted by @dedrisian-oai in #2890 (comment)

Both numbered args and named args have been merged! It will be released in the next version :)

Originally posted by @dedrisian-oai in #2890 (comment)

I believe it should be in 0.43.0 when released:

rust-v0.42.0...rust-v0.43.0-alpha.7

etraut-openai · 2025-10-30T23:23:05Z

Thanks for the contribution, and apologies for the slow response. We've received many PRs, and we don't have the bandwidth on the codex team to review all of them.

I think this PR is no longer needed. The linked feature request is marked as completed.
