  Query simd.watch for Solana Improvement Documents (SIMDs) and feature gate
  activation status. Use this skill whenever the user asks about: SIMD proposals
  (status, author, category, details), feature gates (pending/active/inactive by
  network), validator upgrade readiness (Agave/Firedancer/Jito version requirements),
  stake-weighted version distribution, or network upgrade progress. Covers the full
  lifecycle from proposal to on-chain activation across Devnet, Testnet, and Mainnet-Beta.

# simd.watch

A SIMD-centered operational view for activation, readiness, and rollout decisions.
Tracks 100+ SIMDs and 60+ feature gates across Devnet, Testnet, and Mainnet-Beta.
Mental model: **SIMD → feature activation → cluster state → validator readiness**.

## What You Can Answer

### SIMD Proposals
- "What is SIMD-0185?" → Feature details, status, author, category
- "Show all SIMDs in Review status" → Filter by proposal lifecycle stage
- "Which SIMDs are Activated?" → Proposals that completed full activation
- Browse any SIMD at `https://simd.watch/simd/{number}` (e.g. `/simd/0185`)
- Full-page view at `https://simd.watch/simd/{number}/page`

### Feature Gate Status
- "Is SIMD-0185 active on mainnet?" → Check per-network activation
- "What's pending on mainnet?" → List features awaiting activation
- "Which features are active on devnet but not mainnet?" → Cross-network comparison
- Each feature shows: Devnet / Testnet / Mainnet-Beta status (active/pending/inactive)

### Validator Readiness
- "Which validator version is needed for SIMD-0185?" → minAgaveVersion, minFiredancerVersion, minJitoVersion
- "Is the network ready for the next upgrade?" → Compare required versions against stake distribution
- "What percentage of stake runs Firedancer?" → Version distribution analysis

### Stake Distribution
- "How much stake is on Agave 3.1.x?" → Stake-weighted version breakdown
- "What's the supermajority version?" → 66%+ stake threshold analysis

## Canonical Objects

simd.watch is organized around these core objects:

- **SIMD Proposal**: number, title, status (Idea→Draft→Review→Accepted→Implemented→Activated), author, category
- **Feature Gate**: on-chain pubkey with activation state per cluster
- **Cluster Activation**: per-network (Devnet/Testnet/Mainnet) rollout status with activation epochs
- **Validator Readiness**: minimum version requirements (Agave/Firedancer/Jito) and stake-weighted adoption

The canonical entity is the **SIMD**, not a generic feature list.

## Data Sources
- **Solana RPC**: Live feature activation status, epoch info
- **Agave Wiki**: Pending activation schedule, minimum client versions
- **SIMD GitHub**: Proposal metadata (title, status, author, category, content)
- **SFDP API**: Stake-weighted validator version distribution
- **Agave/Firedancer Releases**: Client version history

## API Endpoints

### GET https://simd.watch/api/v1/simds

List all SIMDs with filtering. The primary SIMD-centric endpoint.

Parameters:
- `status`    — `Review` | `Accepted` | `Activated` | etc.
- `category`  — `Core Protocol` | etc.
- `q`         — Search by number, title, or author
- `limit`     — max 500 (default 500)
- `format`    — `json` (default) | `csv`

### GET https://simd.watch/api/v1/simds/:id

Get a specific SIMD with enriched feature gate data.
Example: `GET https://simd.watch/api/v1/simds/0185`

Response: number, title, status, author, category, tldr, summary, githubUrl,
featureGateId, mainnet/testnet/devnetStatus, activation epochs, min versions, canonicalUrl.

### GET https://simd.watch/api/v1/features

List all feature gates with SIMD metadata and activation status.

Parameters:
- `network` — `mainnet` | `testnet` | `devnet` (omit for all)
- `status`  — `active` | `pending` | `inactive` (omit for all)
- `format`  — `json` (default) | `csv`
- `limit`   — max 500 (default 500)

Response fields per feature:
- `id` — feature gate pubkey
- `name`, `simdNumber`, `simdUrl` — SIMD proposal link
- `mainnetStatus`, `testnetStatus`, `devnetStatus` — `active` | `pending` | `inactive`
- `mainnetActivationEpoch`, `testnetActivationEpoch`, `devnetActivationEpoch`
- `minAgaveVersion`, `minFiredancerVersion`, `minJitoVersion`
- `category`, `explorerUrl`

### GET https://simd.watch/api/v1/stake

Stake-weighted validator version distribution (mainnet).

Response fields:
- `totalStake`
- `versions[]` — each with `version`, `stakeAmount`, `stakePercent`, `validatorCount`

## Common Queries

**"What features are pending on mainnet?"**
```
GET https://simd.watch/api/v1/features?network=mainnet&status=pending
```

**"What validator version is needed for SIMD-0185?"**
```
GET https://simd.watch/api/v1/features?network=mainnet
```
Filter response by `simdNumber == "0185"`, read `minAgaveVersion` / `minFiredancerVersion`.

**"Is SIMD-0185 active on mainnet?"**
```
GET https://simd.watch/api/v1/features?network=mainnet
```
Filter by `simdNumber == "0185"`, check `mainnetStatus`.

**"How much stake is on Agave 3.1.x?"**
```
GET https://simd.watch/api/v1/stake
```
Sum `stakePercent` for versions matching `3.1.*`.

**"Is the network ready for SIMD-0185?"**
1. Get feature: filter `/api/v1/features` by `simdNumber == "0185"`
2. Note `minAgaveVersion` (e.g. `v3.1.0`)
3. Get stake: `/api/v1/stake`
4. Sum stake on versions >= `3.1.0`
5. Supermajority = 66%+ of total stake
