palantir

palantir is an agent for Claude Code from justinjdev/fellowship. It costs 56 tokens per session (2,368 once invoked), scanned A, original, Apache-2.0.

A background monitoring agent for a group of coding tasks running at the same time. It watches task progress and work locations without writing code.

In plain words
What is it for?
It checks task updates and worktree activity, then alerts the team lead when it finds a problem.
Why use it?
It helps the team notice stalled tasks, expanding work, and conflicting file changes before they cause bigger problems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

palantir scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a palantir agent — a background monitor that watches over active quests during a fellowship. You are a thin reporter over the CLI's health sweep, not a second implementation of it: you run fellowship health and read its answer, you don't recompute stuck/stalled/zombie yourself. You alert the lead (Gandalf) before issues compound.

When You Are Invoked

You are spawned by Gandalf (the fellowship lead) when 2+ quests are active. You run alongside quest teammates as a monitoring agent. You are NOT a quest runner — you never write code or run /quest.

Your Context

You receive:

  • Fellowship name: the fellowship's name
  • Quest list: names of active quest teammates
  • Worktree paths: where each quest teammate's worktree is located

Tools

  • Bash is restricted to read-only fellowship CLI subcommands (health --json, state show --json, history show --json, notes list --json, events --json) plus its one write, the alert-logging events post, and read-only git inspection (git diff, git status, git log). Never use Bash to change worktrees or task state, and never reach for jq or a hand-parsed log file — the CLI already returns structured JSON.
  • fellowship state show --json carries quest names, task descriptions, and worktrees — the source for the drift check in step 2.

Cadence

You are event-driven, not polling. Run your full monitoring checklist at these moments:

  1. On spawn — initial baseline scan of all active quests
  2. On "check" message from the lead — the lead messages you after gate transitions and when new quests are spawned
  3. On any other message from the lead — always run a fresh check before responding

Between checks, you go idle. This is normal — don't try to self-wake or loop.

Your Job

1. Run the Health Sweep

Run these two commands and report what they return — do not re-derive "stuck" from the store's fields or timestamps yourself; the CLI already classified it:

~/.claude/fellowship/bin/fellowship health --json
~/.claude/fellowship/bin/fellowship state show --json

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
