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 | $0.00111 | $0.02006 |
| Opus 5 | $0.00056 | $0.01003 |
| Sonnet 5 | $0.00022 | $0.00401 |
| Haiku 4.5 | $0.00011 | $0.00201 |
Grade A, and why
web-security scanned grade A with 1 finding 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 yesterday.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Web Security
Comprehensive web application security patterns covering OWASP Top 10 (2021). Apply before code review, not after.
OWASP analysis is prose judgment — the model reasons about attack vectors, code patterns, and mitigations. OWASP coverage is deterministic — the script validates that every finding maps to a real OWASP category and reports which of the 10 categories have zero findings (the blind spots).
Never report a "clean" security review without running the coverage checker.
OWASP Top 10 (2021) — Quick Reference
| Code | Category | Core Risk |
|---|---|---|
| A01 | Broken Access Control | Unauthorized access, IDOR, privilege escalation |
| A02 | Cryptographic Failures | Plaintext storage, weak algorithms, missing TLS |
| A03 | Injection | SQL, NoSQL, OS, LDAP injection; XSS |
| A04 | Insecure Design | Missing threat model, no security requirements |
| A05 | Security Misconfiguration | Default creds, verbose errors, open CORS |
| A06 | Vulnerable and Outdated Components | CVE-carrying dependencies |
| A07 | Identification and Authentication Failures | Weak passwords, no MFA, session issues |
| A08 | Software and Data Integrity Failures | Unsigned updates, unsafe deserialization |
| A09 | Security Logging and Monitoring Failures | Undetected breaches, missing audit logs |
| A10 | Server-Side Request Forgery (SSRF) | Internal service access via user-controlled URLs |
Invocation — OWASP Coverage Scorer (L3 Script)
After identifying findings, assemble them as a JSON array and run the scorer. Consume its output only — the script source never enters context.
Format each finding:
[
{
"title": "Admin endpoint lacks authentication check",
"owasp": "A01",
"severity": "Critical",
"status": "open"
}
]
OWASP field: Use short codes A01–A10, or full OWASP 2021 category names (e.g. "Injection"), or common shorthands ("SSRF", "IDOR", "sqli", "authentication").
severity field (optional): Critical | High | Medium | Low
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.

web-security is a skill published in the GitHub repository Everyone-Needs-A-Copilot/claude-copilot (13 stars, last pushed yesterday), licensed MIT. It adds 111 tokens to every session and 2,006 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
Other skills, from other repositories
ship-first
Final task completion protocol: report → user-note → deploy → smoke test → close? → guide? → routing.db → propagate → STATUS → sessions. Invoked from fast-track and pipeline flows after task execution, not directly by the user. Use when: invoked after the execute step of a fast-track or pipeline task.
ui-ai-first
Final audit of a large task before closure — finds which operations are available only via code / curl / SQL and decides per each: automate with a skill or AI agent (A) or create a UI task (B). Protects against invisible usability debt. Walks through each implemented block: reads task.md + reports + guides + code →…
cadence-first
Meta-orchestrator: assigns skill-chain cadence per block (Tier 1/2/3) via Q1-Q6 rules. Reads target taskblocks + task.md, writes cadence-decisions-{R}.md artifact. Standalone (executor invokes) or Batch (generator hand-off). Use when: deciding cadence for a batch of blocks, generator hand-off from decomposition skills.
decision-first
Makes an architectural / project / scope decision using a 5-part model INSTEAD of asking the user. Structure: 🎯 Decision / Why / 🛡 Security / 📈 Scalability / Alternatives / Plain-language analogy. 1 question = 1 atomic artifact. Use when: the agent is about to ask an architectural / scope question…
library-first
Mandatory protocol before executing any fast-track task. Analyzes the task, builds a table: what we do / where it comes from / how many lines of code. Principle: maximum reuse of existing libraries and components, minimum new code. Waits for explicit user approval — does nothing until confirmed. Use when: fast-track…
fixture-new
Creates a parity fixture — the frozen scenario plus the contract its output must satisfy. Asks which skill and case, what shape the run must produce, and writes input.md and expect.yml. Ends by proving the new fixture actually fails on an empty directory. A fixture that passes when nothing ran is worse than no…
