docs(website): dedicated page per bundled + optional skill (#14929) 
Generates a full dedicated Docusaurus page for every one of the 132 skills
(73 bundled + 59 optional) under website/docs/user-guide/skills/{bundled,optional}/<category>/.
Each page carries the skill's description, metadata (version, author, license,
dependencies, platform gating, tags, related skills cross-linked to their own
pages), and the complete SKILL.md body that Hermes loads at runtime.

Previously the two catalog pages just listed skills with a one-line blurb and
no way to see what the skill actually did — users had to go read the source
repo. Now every skill has a browsable, searchable, cross-linked reference in
the docs.

- website/scripts/generate-skill-docs.py — generator that reads skills/ and
  optional-skills/, writes per-skill pages, regenerates both catalog indexes,
  and rewrites the Skills section of sidebars.ts. Handles MDX escaping
  (outside fenced code blocks: curly braces, unsafe HTML-ish tags) and
  rewrites relative references/*.md links to point at the GitHub source.
- website/docs/reference/skills-catalog.md — regenerated; each row links to
  the new dedicated page.
- website/docs/reference/optional-skills-catalog.md — same.
- website/sidebars.ts — Skills section now has Bundled / Optional subtrees
  with one nested category per skill folder.
- .github/workflows/{docs-site-checks,deploy-site}.yml — run the generator
  before docusaurus build so CI stays in sync with the source SKILL.md files.

Build verified locally with `npx docusaurus build`. Only remaining warnings
are pre-existing broken link/anchor issues in unrelated pages.

Solana

Query Solana blockchain data with USD pricing — wallet balances, token portfolios with values, transaction details, NFTs, whale detection, and live network stats. Uses Solana RPC + CoinGecko. No API key required.

:::info The following is the complete skill definition that Hermes loads when this skill is triggered. This is what the agent sees as instructions when the skill is active. :::

Solana Blockchain Skill

Query Solana on-chain data enriched with USD pricing via CoinGecko. 8 commands: wallet portfolio, token info, transactions, activity, NFTs, whale detection, network stats, and price lookup.

No API key needed. Uses only Python standard library (urllib, json, argparse).

When to Use

  • User asks for a Solana wallet balance, token holdings, or portfolio value
  • User wants to inspect a specific transaction by signature
  • User wants SPL token metadata, price, supply, or top holders
  • User wants recent transaction history for an address
  • User wants NFTs owned by a wallet
  • User wants to find large SOL transfers (whale detection)
  • User wants Solana network health, TPS, epoch, or SOL price
  • User asks "what's the price of BONK/JUP/SOL?"

Prerequisites

The helper script uses only Python standard library (urllib, json, argparse). No external packages required.

Pricing data comes from CoinGecko's free API (no key needed, rate-limited to ~10-30 requests/minute). For faster lookups, use --no-prices flag.

Quick Reference

RPC endpoint (default): https://api.mainnet-beta.solana.com Override: export SOLANA_RPC_URL=https://your-private-rpc.com

Helper script path: ~/.hermes/skills/blockchain/solana/scripts/solana_client.py

python3 solana_client.py wallet   <address> [--limit N] [--all] [--no-prices]
python3 solana_client.py tx       <signature>
python3 solana_client.py token    <mint_address>
python3 solana_client.py activity <address> [--limit N]
python3 solana_client.py nft      <address>
python3 solana_client.py whales   [--min-sol N]
python3 solana_client.py stats
python3 solana_client.py price    <mint_or_symbol>

Procedure

0. Setup Check

python3 --version

# Optional: set a private RPC for better rate limits
export SOLANA_RPC_URL="https://api.mainnet-beta.solana.com"

# Confirm connectivity
python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py stats

1. Wallet Portfolio

Get SOL balance, SPL token holdings with USD values, NFT count, and portfolio total. Tokens sorted by value, dust filtered, known tokens labeled by name (BONK, JUP, USDC, etc.).

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py \
  wallet 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM

Flags:

  • --limit N — show top N tokens (default: 20)
  • --all — show all tokens, no dust filter, no limit
  • --no-prices — skip CoinGecko price lookups (faster, RPC-only)

Output includes: SOL balance + USD value, token list with prices sorted by value, dust count, NFT summary, total portfolio value in USD.

2. Transaction Details

Inspect a full transaction by its base58 signature. Shows balance changes in both SOL and USD.

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py \
  tx 5j7s8K...your_signature_here

Output: slot, timestamp, fee, status, balance changes (SOL + USD), program invocations.

3. Token Info

Get SPL token metadata, current price, market cap, supply, decimals, mint/freeze authorities, and top 5 holders.

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py \
  token DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263

Output: name, symbol, decimals, supply, price, market cap, top 5 holders with percentages.

4. Recent Activity

List recent transactions for an address (default: last 10, max: 25).

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py \
  activity 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM --limit 25

5. NFT Portfolio

List NFTs owned by a wallet (heuristic: SPL tokens with amount=1, decimals=0).

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py \
  nft 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM

Note: Compressed NFTs (cNFTs) are not detected by this heuristic.

6. Whale Detector

Scan the most recent block for large SOL transfers with USD values.

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py \
  whales --min-sol 500

Note: scans the latest block only — point-in-time snapshot, not historical.

7. Network Stats

Live Solana network health: current slot, epoch, TPS, supply, validator version, SOL price, and market cap.

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py stats

8. Price Lookup

Quick price check for any token by mint address or known symbol.

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py price BONK
python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py price JUP
python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py price SOL
python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py price DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263

Known symbols: SOL, USDC, USDT, BONK, JUP, WETH, JTO, mSOL, stSOL, PYTH, HNT, RNDR, WEN, W, TNSR, DRIFT, bSOL, JLP, WIF, MEW, BOME, PENGU.

Pitfalls

  • CoinGecko rate-limits — free tier allows ~10-30 requests/minute. Price lookups use 1 request per token. Wallets with many tokens may not get prices for all of them. Use --no-prices for speed.
  • Public RPC rate-limits — Solana mainnet public RPC limits requests. For production use, set SOLANA_RPC_URL to a private endpoint (Helius, QuickNode, Triton).
  • NFT detection is heuristic — amount=1 + decimals=0. Compressed NFTs (cNFTs) and Token-2022 NFTs won't appear.
  • Whale detector scans latest block only — not historical. Results vary by the moment you query.
  • Transaction history — public RPC keeps ~2 days. Older transactions may not be available.
  • Token names — ~25 well-known tokens are labeled by name. Others show abbreviated mint addresses. Use the token command for full info.
  • Retry on 429 — both RPC and CoinGecko calls retry up to 2 times with exponential backoff on rate-limit errors.

Verification
