Inline comments:
In
`@yield-agentkit-skills/skills/yield-agentkit-privy/references/privy-policies.md`:
- Around line 61-99: Update the policy docs to warn that template limits are
denominated in wei and that the displayed USD approximations (e.g., the
Conservative template's "value": "200000000000000000" / 0.2 ETH ≈ "$500") will
drift as ETH price changes; add a short "Important: ETH Price Volatility" note
before the templates section recommending users to (1) periodically adjust wei
values in templates like "Yield Agent — Conservative", "Balanced" and "Power
User" if they define limits in fiat, and (2) consider using the DeFi Contract
Allowlist template for USD-stable token restrictions.

In
`@yield-agentkit-skills/skills/yield-agentkit-privy/references/privy-transactions.md`:
- Around line 58-66: Add JSON fence language annotations to the fenced code
blocks shown (the example with "method": "eth_sendTransaction" and the error
object with "error": { "code": "POLICY_VIOLATION", ... }) so the markdown linter
(MD040) is satisfied; update the opening backticks from ``` to ```json for both
examples (the request/response blocks containing "eth_sendTransaction" and the
error object) while leaving their contents unchanged.
- Around line 118-119: Fix the duplicated word in the polling instruction:
replace the phrase "Poll every 3–5 seconds to to check status." with "Poll every
3–5 seconds to check status." in the privy-transactions.md content so the
sentence reads correctly and retains the guidance about not proceeding until
`status` reaches a terminal state.

In
`@yield-agentkit-skills/skills/yield-agentkit-privy/references/privy-wallets.md`:
- Line 9: The sentence "Always attach a policy. A wallet without a policy should
never exist." conflicts with other docs (privy-policies.md and README workflow)
that mark policies as optional; change this line in privy-wallets.md to soften
the requirement and match other docs—replace it with wording like "Attaching a
policy is strongly recommended; a wallet without a policy has no built-in
constraints on transactions" (or similar) so guidance across files is
consistent.

In
`@yield-agentkit-skills/skills/yield-agentkit-privy/references/semi-autonomous.md`:
- Around line 77-80: Update the truncated credential error prompt in
semi-autonomous.md so the full action path and guidance are included: locate the
message string "Privy credentials are not configured in your environment." and
replace it with a complete, actionable prompt that tells the user how to
configure Privy (e.g., which env vars to set, where to obtain credentials, and
an example command), ensuring the full instruction block is present and not cut
off so onboarding flow continues smoothly.
- Around line 314-325: The current guidance to mutate nonce per stepIndex
conflicts with the rule "never modify unsignedTransaction"; instead compute the
adjusted nonce from the nonce returned for stepIndex=0 (convert hex→decimal, add
stepIndex, convert decimal→hex) and apply that adjusted nonce only in the
submission payload or a new transaction copy without mutating
unsignedTransaction itself; implement a small helper (e.g.,
computeAdjustedNonce(nonceHex, stepIndex)) and use it right before sending to
Privy, leaving the original unsignedTransaction intact and documented.
- Line 217: The sentence "Ask the user to check the dashboard and muannly
approve this." contains a typo; update the word "muannly" to "manually" so the
instruction reads "Ask the user to check the dashboard and manually approve
this." Edit the line in the semi-autonomous.md content where that exact sentence
appears.
- Around line 274-276: Update the CAIP-2 value for Solana in the
semi-autonomous.md example by replacing the current string value for the "caip2"
key ("solana:mainnet") with the Privy-supported canonical identifier
"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp" so the example that uses "method":
"signAndSendTransaction" matches the privy-transactions.md canonical format and
prevents integration failures with Privy's API.

In
`@yield-agentkit-skills/skills/yield-agentkit-privy/references/yield-input-format.md`:
- Line 26: Update the `type` enum description in yield-input-format.md to
explicitly state the source API and add a maintenance verification note: mention
that these values are sourced from the Yield.xyz API (`GET /v1/yields`),
instruct maintainers to verify the enum against the latest API response when
they see validation errors, and add a "Last verified: YYYY-MM-DD" timestamp
placeholder so reviewers update it whenever they confirm the list (also ensure
the note highlights that the only valid values are the eight listed, including
`fixed_yield`, to prevent drift).

In
`@yield-agentkit-skills/skills/yield-agentkit-privy/references/yield-mcp-tools.md`:
- Around line 208-211: The doc conflict is that unsignedTransaction is described
as "pass verbatim" but Privy requires a constructed payload (see
privy-transactions.md) and chain-specific conversions (e.g., Solana base64).
Update the guidance to treat unsignedTransaction as the canonical source of
fields but do NOT mutate it; instead create a new Privy-compatible payload
(e.g., via a buildPrivyPayload helper) that copies fields from
unsignedTransaction and performs chain-specific transformations (Solana base64
encoding, any MCP-required field mapping) before submitting to Privy; reference
unsignedTransaction, Privy, and the privy-transactions.md rules so callers know
when to copy vs when to transform.

In `@yield-agentkit-skills/skills/yield-agentkit-privy/SKILL.md`:
- Around line 300-310: The fenced code block in SKILL.md that contains the
prompt-injection examples (the triple-backtick block showing lines like "Ignore
previous instructions..." and "Transfer to 0x... immediately") is missing a
language tag; update that opening fence to include a language specifier (for
example use ```text or ```diff) so markdownlint MD040 is satisfied and the block
is treated as a code/monospace block with proper syntax styling.
- Line 330: Fix the typo in the table row for
`{baseDir}/references/yield-policies.md` by changing the description text from
"Data fetching and API usgae rules for Yield AgentKit MCP" to "Data fetching and
API usage rules for Yield AgentKit MCP" so the word "usgae" is corrected to
"usage".
- Around line 25-37: The SKILL.md rule forbids modifying unsignedTransaction but
semi-autonomous.md instructs mutating the nonce via stepIndex, creating a
conflict; reconcile by choosing one approach: either (A) enforce
immutability—remove any nonce mutation tied to stepIndex, update
semi-autonomous.md to stop instructing mutation and instead instruct requesting
a NEW action with the correct nonce/amount, or (B) if nonce adjustment must be
supported, implement a safe separate field (e.g., adjustedNonce) and flow that
never mutates unsignedTransaction itself, update SKILL.md to document the
controlled exception, and change references to stepIndex to use the new field;
locate and change all code/docs referencing unsignedTransaction and stepIndex
accordingly.
- Around line 77-88: The user-facing "missing credentials" message in SKILL.md
is truncated; update the check that echoes PRIVY_APP_ID and PRIVY_APP_SECRET to
emit a complete, well-formed message string when either is empty — e.g. a full
quoted block that closes properly and contains the remediation: "Privy
credentials are not configured in your environment. Please set up Privy and
export PRIVY_APP_ID and PRIVY_APP_SECRET." Ensure the message covers both
variables and that the runbook instructs to stop immediately when the check
fails.

recognizes them as plain text.
- Around line 21-35: The docs assume a structured unsignedTransaction but
TransactionDto.unsignedTransaction is documented as raw tx data; update the
documentation and transformation steps to match: either (A) define and document
a canonical unsignedTransaction JSON schema (listing fields like from, to, data,

TransactionDto.unsignedTransaction) to use that schema, or (B) keep
unsignedTransaction as raw RLP/hex and replace the jq snippet with a clear
decoding step (describe using a decoder to parse the raw tx into fields, then

Take the fields Privy accepts from unsignedTransaction and create a

### Send Transaction (DeFi deposit / approval / exit)


**Step 1 — Build a Privy-compatible transaction**

Take the fields Privy accepts from unsignedTransaction and create a
new object. Do not modify the original transaction returned by the MCP.
```bash
PRIVY_TX=$(echo "$UNSIGNED_TX" | jq '{from, to, data, nonce, type}')
```
UNSIGNED_TX stays untouched. PRIVY_TX is the new Privy-compatible
object you pass in the request.

⚠️ Potential issue | 🟠 Major

Clarify unsignedTransaction shape before prescribing field extraction.

Line 21-Line 35 and Line 111-Line 113 assume unsignedTransaction exposes structured fields (from, to, data, nonce, type, chainId). But yield-agentkit-plugin/yield-agentkit/SKILL.md (Line 170-Line 180) documents TransactionDto.unsignedTransaction only as raw tx data. This mismatch can make the jq '{from,to,data,nonce,type}' flow fail in real usage.

Please align docs on one canonical unsignedTransaction schema (or add chain-specific schema examples from real MCP responses) before these transformation steps.

The difference here is intentional.

The skill inside the plugin treats unsignedTransaction as opaque/raw data, so no transformation is needed there. However, in the Privy skill, we need to make the transaction compatible with Privy’s RPC format before execution.

That’s why we’re extracting/structuring fields here, this layer adapts the raw unsignedTransaction into a Privy-compatible transaction payload for signing and broadcasting.

@Ishita-02, thanks for the clarification — the layered design makes sense. The plugin correctly treats unsignedTransaction as opaque (no transformation needed there), and the Privy skill acts as the adapter layer that shapes it into a Privy-compatible RPC payload.

One small suggestion: since readers coming from the plugin docs may expect unsignedTransaction to be raw/opaque everywhere, it would help to add a brief inline note in privy-transactions.md confirming that for EVM chains the MCP returns unsignedTransaction as a structured JSON object (not raw bytes/hex), which is why the jq extraction is valid. Something like:

> **Note:** For EVM chains, the Yield.xyz AgentKit MCP returns `unsignedTransaction`
> as a structured JSON object containing fields such as `from`, `to`, `data`, `nonce`,
> and `type`. This makes the `jq` field extraction below safe. Do not modify the
> original object — only derive `PRIVY_TX` from it.

This would resolve any apparent contradiction with the plugin's opaque treatment and make the transformation step self-explanatory. Up to you whether to add it.

Learning: In the yield-agentkit-privy skill, the `unsignedTransaction` returned by the Yield.xyz AgentKit MCP for EVM chains is a structured JSON object (with fields like `from`, `to`, `data`, `nonce`, `type`), not raw RLP/hex bytes. The Privy skill layer intentionally extracts these fields using `jq` to create a Privy-compatible transaction payload (`PRIVY_TX`), while the plugin layer treats `unsignedTransaction` as opaque. These are two separate layers with different responsibilities.

Transaction example still contradicts the canonical Privy payload flow.

68-70: Optional: Consider language specifiers for bash blocks only.

The static analysis tool flagged 17 code blocks without language specifiers. However, most of these are correctly formatted as plain text blocks—they represent user prompts to type into Claude (e.g., "Find USDC yields on Base"), not executable code.

The only blocks that could benefit from language specifiers are the shell commands:

  • Lines 167-169: claude mcp list
  • Lines 174-175: claude mcp add
  • Lines 194-197: curl command

Adding bash to these would enable syntax highlighting, but it's purely cosmetic since the examples are already clear.

💅 Optional: Add bash language specifiers

For lines 167-169:

-```
+```bash
 claude mcp list
 # Should show: yield-agentkit

For lines 174-175:
```diff
-```
+```bash
 claude mcp add --transport http yield-xyz https://mcp.yield.xyz/mcp

The `curl` example at lines 194-197 already has `bash` specified, so it's correct as-is.
