+description: Function-by-function refactoring loop driven by ideal pseudocode. Use when the user says "ideal pseudocode", asks to make a function read like its pseudocode, or wants a dense module cleaned up one function at a time.
+---
+
+# Ideal Pseudocode
+
+Clean up one function at a time by writing the pseudocode it _should_ read as, naming every delta between that and the real code, and closing only the gaps the user approves.
+
+## Loop
+
+One function per round. Never touch code before the user picks a direction.
+
+1. **Pick the target** with the user — usually the next function up or down the call chain from the last round.
+2. **Read the current code** fresh from disk. It may have unsaved or parallel edits; ask before overwriting anything unexpected.
+3. **Distill.** Write the function's ideal pseudocode in a `ts`-fenced code block — TypeScript-flavored for syntax highlighting, but pseudocode: comments over mechanics, one line per idea, every arm of a loop visible as an arm. For a dense or unfamiliar function, first show the _current_ structure as pseudocode, then the ideal.
+4. **Name the deltas.** A numbered list; each delta is one concrete gap: control flow smuggled through combinators, a flag-typed parameter, colliding names, side-effect plumbing drowning a loop body, twin functions differing only by a filter. For each, give an honest cost/benefit and a decisive recommendation — including "leave it" when the density has reasons (state the reasons).
+5. **Verify before proposing.** Any API the proposal builds on (a combinator, schedule, matcher) gets checked against the installed version's source, not memory.
+6. **Get buy-in, then apply.** Minimal edits. Quarantine irreducible ugliness inside a small helper whose name is the pseudocode line it implements. Collapse shallow sibling functions into one deep function only when the distinguishing argument is a domain noun, not a behavior switch.
+7. **Validate.** Typecheck and the focused test suites from the package directory; rerun timing-sensitive tests repeatedly. Flag any semantic change the restructure introduced, even when tests pass.
+8. **Offer the next target** and stop.
+
+## Style
+
+- Keep each round tight: pseudocode block, deltas, recommendation, one question.
+- State mutation belongs in one visible place (usually the loop tail), never spread across error channels or callback closures.
+- Prefer early return and `if` chains for control flow; matchers are for producing values.
+- Compare names against the question each caller is actually asking; rename toward the domain noun.
+
+## Example round
+
+Every round should read like this (abridged from a real one, on an Effect step-runner):
+
+> `runStep` it is. The ideal pseudocode:
+>
+> ```ts
+> // One logical step: one settled model call, however many attempts it takes.
+> // An attempt can end without settling in two ways:
+> //   transient provider failure -> retry the same call, same assistant message
+> //   compaction rewrote history -> rebuild the request and call again
+> function runStep(session, promotable, step) {
+>   while (true) {
+>     const result = callModel(session, promotable, step)
+>
+>     if (result.completed) return result
+>
+>     if (result.retryable) {
+>       wait(retrySchedule) // exhausted -> publish Step.Failed, fail drain
+>       promotable = none // never re-promote on a second attempt
+>       continue
+>     }
+>
+>     // compaction restarted the step: fresh request from rewritten history
+>     promotable = none
+>     step = result.step
+>   }
+> }
+> ```
+>
+> Comparing against the real thing, three deltas:
+>
+> 1. **The retry arm doesn't live in the loop.** In the pseudocode, retry is just another loop arm. In the real code it's smuggled through the error channel: `Effect.tapError` mutating loop variables via `Effect.sync` closures, then `Effect.retryOrElse` re-running a suspended call. Four mutable variables mutated from three different places — the state flow is invisible unless you already know the trick.
+> 2. **`recoverOverflow: typeof compaction.compact | undefined`** — a function-typed parameter used as a one-shot armed/disarmed flag. The callee already closes over `compaction`; a boolean says what it is.
+> 3. **`assistantMessageID`** exists solely to resume the same durable message across retries — fine, but only legible once the retry arm is visible in the loop.
+>
+> The unifying move for (1): a schedule driver, so a retryable failure becomes a caught value handled in the loop body exactly like the compaction arm. One honest trade: it's more manual than the blessed combinator — but the manual version is the loop the combinator was hiding, and the loop already exists for restarts. Two restart mechanisms, one control structure.
+>
+> Want me to apply it — unified loop, simplified schedule input, boolean `recoverOverflow`?

-name: rtl-aware-development
-description: OpenCode Desktop should be RTL-aware. Use when implementing or reviewing RTL/LTR behavior in the web app, desktop app, CSS, menus, scrolling, resizing, icons, mixed-direction text, or Electron title bars.
----
-
-# RTL-Aware Development
-
-Treat direction as independent from language. Test English in both directions as well as real RTL and mixed-script content.
-
-## Guidelines
-
-- Set `lang` and `dir` on the document, and propagate direction through component providers used by portaled menus and popovers. Do not change the selected locale merely to force RTL.
-- Keep DOM and focus order semantic. Flexbox and Grid already follow `dir`; do not add `row-reverse`, CSS `order`, or reversed markup just to mirror a layout.
-- Prefer logical CSS for semantic layout. Reserve physical coordinates for pointer positions, canvas geometry, native window controls, and other genuinely physical placement.
-
-```css
-/* Avoid */
-padding-left: 12px;
-right: 0;
-border-right: 1px solid;
-text-align: left;
-
-/* Prefer */
-padding-inline-start: 12px;
-inset-inline-end: 0;
-border-inline-end: 1px solid;
-text-align: start;
-```
-
-- Isolate mixed-direction text. Use `dir="auto"` or `<bdi>` for unknown text; keep code, URLs, IDs, and filesystem paths LTR without forcing the surrounding component LTR.
-
-```html
-<span class="file-row"><bdi dir="auto">README.md</bdi></span> <bdi dir="ltr"><code>C:\src\app.ts</code></bdi>
-```
-
-- Mirror directional meaning, not every image. Back/forward, previous/next, disclosure, indentation, and directional progress may need mirroring. Do not mirror brands, clocks, media controls, charts, or text. Reverse physical gradients, `translateX`, SVG transforms, and animation deltas explicitly.
-- Map interactions through direction. `clientX` remains physical; resizing a logical edge needs an RTL-aware delta. Logical previous/next keyboard controls may swap ArrowLeft/ArrowRight. Follow the relevant WAI-ARIA widget pattern.
-- Do not assume LTR scrolling. RTL `scrollLeft` can start at `0` and become negative. Prefer `scrollIntoView({ inline: "nearest" })` or a tested direction-normalizing helper.
-- For Electron title bars, prefer native caption controls and use `titleBarOverlay` plus `env(titlebar-area-*)` for the safe content rectangle. Keep Windows/macOS native-control avoidance and `trafficLightPosition` physical; keep app navigation inside that rectangle logical. Mark interactive titlebar children `app-region: no-drag`.
-- Verify behavior, not screenshots alone. Check computed styles, pseudo-element geometry, hit zones, focus order, keyboard behavior, submenu direction, zoom/scaling, and both LTR and RTL scroll endpoints.
-
-## Test Matrix
-
-- English + LTR
-- English + forced RTL
-- A real RTL locale + RTL
-- Mixed RTL/LTR content, long labels, numbers, code, and paths
-- Keyboard, pointer resize, scrolling, menus/submenus, and Electron titlebar controls in both directions

@@ -252,6 +252,33 @@ These are not strictly enforced, they are just general guidelines:
 
 For net-new functionality, start with a design conversation. Open an issue describing the problem, your proposed approach (optional), and why it belongs in OpenCode. The core team will help decide whether it should move forward; please wait for that approval instead of opening a feature PR directly.
 
+## Trust & Vouch System
+
+This project uses [vouch](https://github.com/mitchellh/vouch) to manage contributor trust. The vouch list is maintained in [`.github/VOUCHED.td`](.github/VOUCHED.td).
+
+### How it works
+
+- **Vouched users** are explicitly trusted contributors.
+- **Denounced users** are explicitly blocked. Issues and pull requests from denounced users are automatically closed. If you have been denounced, you can request to be unvouched by reaching out to a maintainer on [Discord](https://opencode.ai/discord)
+- **Everyone else** can participate normally — you don't need to be vouched to open issues or PRs.
+
+### For maintainers
+
+Collaborators with write access can manage the vouch list by commenting on any issue:
+
+- `vouch` — vouch for the issue author
+- `vouch @username` — vouch for a specific user
+- `denounce` — denounce the issue author
+- `denounce @username` — denounce a specific user
+- `denounce @username <reason>` — denounce with a reason
+- `unvouch` / `unvouch @username` — remove someone from the list
+
+Changes are committed automatically to `.github/VOUCHED.td`.
