SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Agent Snooping · line 339 Skill enumerates or reads other installed skills.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00141 | $0.06365 |
| Opus 5 | $0.00071 | $0.03182 |
| Sonnet 5 | $0.00028 | $0.01273 |
| Haiku 4.5 | $0.00014 | $0.00636 |
Grade A, and why
spike 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 5d 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 — 579 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spike
Codex-first time-boxed technical investigation skill leveraging Codex deep reasoning, Opus 1M context, and Agent Teams.
Preflight: ensure codex CLI is current (see codex-system skill).
Overview
This skill handles time-boxed feasibility studies and technical investigations. It produces a decision document (go/no-go recommendation), NOT an implementation plan. After a GO decision, the user proceeds to /feature (existing or greenfield mode) for actual implementation.
/spike <question or hypothesis> <- This skill (investigation & decision)
| After GO decision
/feature <- Implementation planning
| After approval
/team-execute <- Parallel implementation + review
When to Use
| Situation | Example |
|---|---|
| Technology feasibility | "Can we use WebSocket for real-time sync?" |
| Library evaluation | "Is DuckDB suitable for our analytics pipeline?" |
| Architecture question | "Should we use event sourcing for the order system?" |
| Performance hypothesis | "Can we serve 10k concurrent requests with this stack?" |
| Migration risk | "What would it take to migrate from REST to gRPC?" |
| Integration question | "Can we integrate with the Stripe Connect API for our use case?" |
When NOT to Use
- Bug diagnosis →
/troubleshoot - Known feature to implement →
/feature - Simple library lookup → direct research (Opus subagent)
- Code review →
/team-execute --review-only
Full skill routing: CLAUDE.md section "Routing Policy".
Investigation Modes
| Mode | Description | When to Use |
|---|---|---|
| RESEARCH-ONLY | No code written. Pure analysis from docs, examples, and Codex reasoning. | Library evaluation, architecture questions, migration risk |
| PROTOTYPE | Small throwaway code to validate a specific technical question. Code is NOT production-quality. | Performance hypothesis, API integration feasibility, compatibility testing |
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

spike is a skill published in the GitHub repository DeL-TaiseiOzaki/claude-code-orchestra (195 stars, last pushed today), licensed MIT. It adds 141 tokens to every session and 6,365 once invoked, about $0.0007 per session on Opus 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 2026-08-30.
