What it does

Nla Fulfill is an agent skill from internet-court/internet-court-skill. Fulfill an existing NLA escrow and collect tokens. Use when the user wants to submit fulfillment text for an on-chain escrow, check arbitration results, and collect approved funds. Covers the full fulfill-arbitrate-collect lifecycle.

Its SKILL.md is about 850 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file. Compatibility notes: Requires nla CLI installed (npm install -g nla). Requires a funded Ethereum wallet and access to an EVM chain.

It sits in Legal & Compliance, covering Dispute resolution and Smart contracts. The repository describes itself as: The trust layer for agent-to-agent commerce — natural-language mandates, ERC-7710 delegated permissions, x402 payments, escrow, and dispute resolution as one open, catch-all… The licence is MIT.

When your agent uses it

The user wants to submit fulfillment text for an on-chain escrow
Check arbitration results
Collect approved funds

Example prompts

“/nla-fulfill”

Requirements

Node.js
A credential in PRIVATE_KEY
Compatibility (from SKILL.md): Requires nla CLI installed (npm install -g nla). Requires a funded Ethereum wallet and access to an EVM chain.
Pre-approved tools (allowed-tools): Bash(nla:*), Read

Workflow steps

5 steps, taken from the step headings in SKILL.md.

Understand the escrow
Craft the fulfillment
Submit the fulfillment
Monitor arbitration
Collect tokens (if approved)

What it can do on your machine

Read from SKILL.md and the folder at commit fa89195. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Bash(nla:*)
- Read
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- PRIVATE_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Requires nla CLI installed (npm install -g nla). Requires a funded Ethereum wallet and access to an EVM chain.
From compatibility in the SKILL.md frontmatter.

Context cost

Nla Fulfill loads about 854 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 311 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~61
When it runs · the whole SKILL.md, loaded when a task matches: ~854

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Fulfill NLA Escrow

Help the user fulfill an on-chain escrow by submitting text that satisfies the escrow's demand, then collect the tokens if approved.

Step-by-step instructions

1. Understand the escrow

Get the escrow UID from the user, then check what it demands:

bash

nla escrow:status --escrow-uid <uid>

This shows:

The demand text
Arbitration model and provider
Oracle address
Any existing fulfillments and their arbitration status

2. Craft the fulfillment

Help the user write fulfillment text that satisfies the demand:

Read the demand carefully
The fulfillment text is what the AI arbitrator evaluates against the demand
Be specific and directly address what the demand asks for
The default arbitration prompt evaluates whether the "fulfillment" satisfies the "demand" and returns true/false

3. Submit the fulfillment

bash

nla escrow:fulfill \
  --escrow-uid <escrow_uid> \
  --fulfillment "<fulfillment text>" \
  --oracle <oracle_address>

This runs a multi-step on-chain commit-reveal flow:

Computes a commitment hash
Submits the commitment with a bond
Waits for next block confirmation
Reveals the fulfillment obligation and returns the bond
Requests arbitration from the oracle

The command outputs a fulfillment UID - record this for collection.

4. Monitor arbitration

Check if the oracle has made a decision:

bash

nla escrow:status --escrow-uid <escrow_uid>

The oracle typically responds within seconds if it's running. Look for "APPROVED" or "REJECTED" in the output.

5. Collect tokens (if approved)

Once the oracle approves:

bash

nla escrow:collect \
  --escrow-uid <escrow_uid> \
  --fulfillment-uid <fulfillment_uid>

This transfers the escrowed tokens to the fulfiller.

Key details

The fulfillment text is permanently recorded on-chain
The commit-reveal process requires gas for multiple transactions
If rejected, the tokens stay in escrow - another fulfillment attempt can be made by anyone
The oracle address must match what was specified when the escrow was created (visible in status output)
Collection only succeeds after the oracle records an approval

Prerequisites

nla CLI installed and configured
Private key set via nla wallet:set, --private-key flag, or PRIVATE_KEY env var
ETH in the fulfiller's account for gas
The oracle must be running (or use the public demo on Sepolia)

Example full flow

bash

# 1. Check what the escrow demands
nla escrow:status --escrow-uid 0xabc123...

# 2. Submit fulfillment
nla escrow:fulfill \
  --escrow-uid 0xabc123... \
  --fulfillment "The sky appears blue due to Rayleigh scattering" \
  --oracle 0x70997970C51812dc3A010C7d01b50e0d17dc79C8

# 3. Check arbitration result
nla escrow:status --escrow-uid 0xabc123...

# 4. Collect if approved
nla escrow:collect \
  --escrow-uid 0xabc123... \
  --fulfillment-uid 0xdef456...
