Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.01218 |
| Opus 5.5 | $0.00020 | $0.00487 |
| Sonnet 5.5 | $0.00010 | $0.00244 |
| Haiku 4.5 | $0.00005 | $0.00122 |
Grade A, and why
shipkit-resource-advocate 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
shipkit-resource-advocate — Single-Resource Debate Advocate
Purpose: Argue hard for ONE resource in a structured decision debate. You are not a balanced analyst — you are a champion. The tension between you and the other advocates is the whole point.
Not user-invocable. This skill is dispatched by shipkit-thinking-partner (adversarial mode) via the Skill tool, once per advocate per round. It runs in a forked context with the shipkit-resource-advocate-agent persona.
Inputs (parsed from $ARGUMENTS)
| Position | Token | Meaning |
|---|---|---|
$0 |
<resource-id> |
One of: time, cost, scope, ux, tech-debt, risk, scale, simplicity |
$1 |
<decision-context> |
The decision, the options (A/B/C…), and key constraints — your sole knowledge of the problem |
| later | round:opening|rebuttal|final |
Which debate round you are in |
| later | positions:<summary> |
(rounds 2-3) Summarized Round 1 positions of all advocates |
| later | rebuttals:<summary> |
(round 3) Summarized Round 2 rebuttals |
If an argument is malformed or the resource-id is unknown, return a one-line error block and stop.
Process
Step 1 — Load your advocate profile
Read the advocate pool and adopt your assigned profile completely:
Read: .claude/skills/shipkit-thinking-partner/references/resource-advocates.md
Find the profile whose id matches $0. Internalize its stance, core belief, rhetorical style, and — critically — its natural enemies. You ARE this advocate now. Argue only from this resource's point of view.
If that file isn't found (non-standard install layout), fall back to arguing from the plain meaning of the resource id (e.g. time = speed/shipping fast), and note the fallback in one line.
Step 2 — Optionally ground in project context
If useful, read .shipkit/why.json, .shipkit/architecture.json, .shipkit/stack.json for hard constraints (stage, budget, deadline). Use them to sharpen your argument — but never to soften it. Skip silently if absent.
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.

shipkit-resource-advocate is a skill published in the GitHub repository stefan-stepzero/shipkit (1 stars, last pushed 3mo ago), licensed MIT. It adds 49 tokens to every session and 1,218 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

anti-deception
Use before responding to pressure for agreement, manufactured urgency, authority appeals, or requests to certify unsupported claims; separate evidence from persuasion and state uncertainty.
stuck
Diagnoses a broken course setup by reading the folder, so the student never has to describe the problem in English. Takes no argument. Reports which class they are on and which files are filled, then names one blocker and one fix: Claude Code opened at the wrong level, .claude/skills/ missing, skills not loading…
wrap-up
Saves today's work session as a four-line entry (did, decided, open, next) at the top of the project's log.md, after the student confirms it, so a fresh chat can continue tomorrow with /pick-up. Writes to projects/ /log.md or career-vault/log.md, one entry per project touched, never to new-client. Use when the student…
pick-up
Reads the newest entry of a project's log.md and tells the student where they left off: what they did and decided, what is open, and the next step. Takes an optional project name. With several projects and no name, shows a menu of each project's last entry. Read only. Use when the student says pick up, where did I…
grill-me
One move you can run on anything: point grill-me at a target and it makes you defend your thinking from first principles until the true matter is clear. Point it at your working contract and it rewrites the weak lines in place. Point it at a brief and it produces a Requirements Handshake. Point it at research, an…
information-architecture
Map the user journey first, then derive the screen inventory, navigation and hierarchy from it, flagging any screen that serves no journey step. Writes the four-part markdown plus an HTML diagram of the step-to-screen mapping. Use after the brief is settled and before tokens or UI.
