What it does

Palantir Webhooks Events is an agent skill from jeremylongshore/tons-of-skills-marketplace. Choose and implement a supported Foundry event path using OSDK object subscriptions, direct WebSocket subscriptions, monitoring webhooks, or Data Connection webhooks. Use when reacting to object or monitoring changes. Trigger with "Palantir events" or "Foundry subscription".

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Requires current Palantir Foundry documentation and approved access for any live resource, permission, data, build, application, or deployment change

It sits in Backend & APIs, covering Webhooks and Realtime and WebSockets. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Reacting to object
  • Monitoring changes
  • With Palantir events
  • Foundry subscription

Example prompts

  • “Palantir events”
  • “Foundry subscription”
  • “/palantir-webhooks-events”

Requirements

  • Compatibility (from SKILL.md): Requires current Palantir Foundry documentation and approved access for any live resource, permission, data, build, application, or deployment change
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Write, Edit

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Classify the event need as Ontology object-set change, monitoring notification, or another documented Foundry integration.
  2. Choose TypeScript OSDK subscription, direct WebSocket, or monitoring/Data Connection webhook and document why it matches.
  3. Define bounded object filters or monitoring criteria, returned properties/message content, authentication, reconnect/backoff, and…
  4. Implement idempotency and durable reconciliation; on onOutOfDate, disconnection, or delivery gap, reload authoritative state.
  5. Test create/update/delete or alert cases, duplicate delivery, reconnect, stale state, denied access, secret rotation, and consumer recovery.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. 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:

    • Read
    • Glob
    • Grep
    • Write
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    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 no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Requires current Palantir Foundry documentation and approved access for any live resource, permission, data, build, application, or deployment change

    From compatibility in the SKILL.md frontmatter.

Context cost

Palantir Webhooks Events loads about 1.4k tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 75 tokens; SKILL.md has 612 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

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.

Palantir Event and Subscription Integration

Overview

Start from the event producer and delivery guarantee: real-time Ontology object updates use OSDK or Object Set Watcher WebSocket subscriptions, while monitoring notifications and outbound integrations use their documented webhook surfaces. Never invent a general ontology.object.created registration API.

Prerequisites

  • Identify the producer, consumer, object set or monitoring view, supported delivery surface, data sensitivity, latency objective, and recovery behavior.
  • Confirm the generated OSDK version or direct WebSocket contract, or the configured Data Connection webhook required by monitoring.
  • Read references/official-docs.md and verify target-enrollment feature access.
  • Prepare a non-production object set or monitoring view and an idempotent consumer.

Current Contract

  • TypeScript OSDK subscriptions require a compatible generated OSDK/client and receive object-set updates through .subscribe.
  • Direct Object Set Watcher subscriptions use a documented WebSocket endpoint and authenticate with a bearer token encoded in the WebSocket subprotocol format.
  • Subscriptions can report an out-of-date state that requires reloading the full object set.
  • Monitoring views can route notifications through webhooks configured in Data Connection; that is distinct from Ontology object subscriptions.

Authentication

Use the generated OSDK token provider or the documented WebSocket bearer subprotocol. For outbound webhooks, use the authentication configured by the supported Data Connection webhook. Never invent or assume a signature header; record the actual configured authentication and secret owner.

Instructions

  1. Classify the event need as Ontology object-set change, monitoring notification, or another documented Foundry integration.

  2. Choose TypeScript OSDK subscription, direct WebSocket, or monitoring/Data Connection webhook and document why it matches.

  3. Define bounded object filters or monitoring criteria, returned properties/message content, authentication, reconnect/backoff, and cancellation.

  4. Implement idempotency and durable reconciliation; on onOutOfDate, disconnection, or delivery gap, reload authoritative state.

  5. Test create/update/delete or alert cases, duplicate delivery, reconnect, stale state, denied access, secret rotation, and consumer recovery.

Tool Discipline

  • Use Glob to locate candidate repositories, manifests, configurations, and evidence without widening scope.
  • Use Grep to find relevant identifiers, declarations, permissions, errors, and stale claims.
  • Use Read to inspect the smallest required files and authoritative evidence.
  • Use Write only for a new approved local draft, test, manifest, or evidence artifact.
  • Use Edit only for a bounded approved change whose rollback is known.
  • Do not use file tools as a substitute for authenticated Foundry operations or owner approval.

Approval Boundaries

Ontology and data owners approve subscribed objects/properties; security owners approve authentication and outbound destinations; monitoring owners approve notification routing. A subscription does not authorize writeback.

Output

An event contract with producer, supported surface, filter, payload fields, auth, consumer, delivery/reconnect behavior, idempotency key, reconciliation, tests, observability, and disable procedure.

Error Handling

ConditionResponse
The requested event has no documented surfaceDo not invent one; use polling with an approved budget, a supported monitoring route, or ask Palantir Support.
The subscription reports out of dateReload the bounded authoritative object set and reconcile before processing more deltas.
WebSocket reconnect loopsApply bounded backoff, refresh auth as designed, and alert after the retry budget.
A webhook auth header is assumedStop and inspect the actual Data Connection webhook configuration.

Examples

Example 1

Subscribe to an approved Equipment object set with TypeScript OSDK, select only required properties, handle updates and deletion, and reload on onOutOfDate.

Example 2

Route a monitoring-view severity to a preconfigured Data Connection webhook, validate the Message input mapping, destination controls, duplicate handling, and disable path.

Validation

  • The chosen surface is explicitly documented for the producer.
  • Filters and returned data are least privilege.
  • Authentication and secret rotation match the selected surface.
  • Duplicates, disconnects, out-of-date state, and reconciliation are tested.
  • Consumer failure cannot silently lose authoritative state.
