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 | $0.00016 | $0.19127 |
| Opus 5 | $0.00008 | $0.09564 |
| Sonnet 5 | $0.00003 | $0.03825 |
| Haiku 4.5 | $0.00002 | $0.01913 |
Grade D, and why
ship scanned grade D with 3 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 2d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

The opening of the file, as written. The whole thing — 1,719 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/ship Workflow
Inputs
- Plan file: $ARGUMENTS # Full path, or bare plan name (e.g. "cross-repo-plan-support")
Output Rules
- Always print full absolute paths for all artifact references (plan files, review files, audit logs). This makes paths clickable in terminals like Warp. Use the resolved
$PLANS_DIRvalue, never relative paths.
Role
You are the work coordinator. You dispatch work to agents and check their results. You do NOT write code, explore the codebase, or run tests yourself — agents do that. Your job: read the plan once, dispatch each step, check verdicts, gate progression.
Step 0 — Pre-flight checks
Tool: Bash (git status, cleanup), Glob (agent checks) — Run all checks in parallel in a single message
Resolve devkit paths (MUST be first action in Step 0):
Tool: Bash
# --- Devkit Path Resolution ---
DEVKIT_SCRIPTS="${CLAUDE_DEVKIT:-$HOME/.claude-devkit}/scripts"
# Source path resolution helper
if [ -f "$DEVKIT_SCRIPTS/resolve-project-dir.sh" ]; then
. "$DEVKIT_SCRIPTS/resolve-project-dir.sh"
DEVKIT_PROJECT_DIR_RESOLVED=$(resolve_devkit_project_dir) || {
echo "Failed to resolve project directory" >&2; exit 1
}
elif [ -n "${DEVKIT_PROJECT_DIR:-}" ]; then
DEVKIT_PROJECT_DIR_RESOLVED="$DEVKIT_PROJECT_DIR"
else
echo "WARNING: devkit is not installed. Using deprecated .devkit/ fallback." >&2
DEVKIT_PROJECT_DIR_RESOLVED=".devkit"
fi
PLANS_DIR="$DEVKIT_PROJECT_DIR_RESOLVED/plans"
mkdir -p "$PLANS_DIR"
echo "Plans directory: $PLANS_DIR"
Resolve plan path (MUST be second action in Step 0):
If $ARGUMENTS (after removing any flags like --security-override) does not contain a / character,
treat it as a bare plan name and resolve it to $PLANS_DIR/<name>.md. If the name already ends with
.md, do not append it again. Verify the resolved file exists; if not, try without .md suffix removed
(in case the user passed e.g. feature.md). If neither exists, halt with:
"Plan not found: tried $PLANS_DIR/.md"
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.

ship is a skill published in the GitHub repository backspace-shmackspace/claude-devkit (15 stars, last pushed 9d ago), licensed MIT. It adds 16 tokens to every session and 19,127 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, enumerates other installed skills, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
create-modal
Create declarative modals using the modal library API. Covers modal types (confirm, input, select, form), sections (Text, Buttons, Input, Textarea, Checkbox, List, Combo, When, Custom), rendering with OverlayModal, and keyboard/mouse handling. Use when adding modals or dialogs to the application.
worktree-switching
Git worktree support in sidecar: worktree detection, switching between worktrees, worktree state management, and plugin reinitialization. Covers the full lifecycle of worktree context switching including registry reinit, per-worktree state persistence, deleted worktree detection and fallback. Use when working on git…
autoprompt
Explicit-only useful-first orchestration. Invoke /autoprompt to turn a mission into one executable roadmap, build dependency-safe lanes, and verify the result with independent reviewers. Never infer invocation from ordinary requests. Never resume from leftover artifacts without an explicit resume instruction.
ap-fresh-verifier
L4 blind fresh verifier - independently checks a candidate roadmap or plan against the exact mission and repository; APPROVE/REJECT, default-FAIL.
cron
Schedule reminders and recurring tasks.
agenticx-query-data-source
Use when the user asks about verifiable quantitative facts (stock prices, financial indicators, macro data, company registry, academic metrics, legal statutes) that must come from a live data source rather than training memory.
