phase-3-risks

phase-3-risks is a skill for Claude Code, Codex from exchanet/method_enterprise_builder_planning. It costs 22 tokens per session (627 once invoked), scanned A, original, MIT.

A security and technical risk-planning guide for an API or other system. STRIDE is a checklist for threats such as impersonation, data changes, information leaks, service disruption, and privilege abuse.

In plain words
What is it for?
Use it to threat-model an API, build a technical risk catalogue, score risks, and record ways to reduce critical risks.
Why use it?
It organizes risks by likelihood and impact and requires mitigations for the most serious threats before implementation continues.

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

phase-3-risks 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 2mo 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.

Skill: Phase 3 — Risk Matrix

Purpose

Execute Phase 3: perform STRIDE threat modeling on the primary API surface, build a technical risk catalog, and ensure all CRITICAL risks have mitigations before proceeding to implementation.

STRIDE Analysis Template

Threat Component Attack vector Severity Mitigation
Spoofing [Component] [Attack] HIGH/CRITICAL [Mitigation]
Tampering [Component] [Attack] HIGH/CRITICAL [Mitigation]
Repudiation [Component] [Attack] MEDIUM/HIGH [Mitigation]
Info Disclosure [Component] [Attack] CRITICAL [Mitigation]
Denial of Service [Component] [Attack] HIGH [Mitigation]
Elevation of Privilege [Component] [Attack] CRITICAL [Mitigation]

Technical Risk Catalog Template

Risk Probability Impact Score Mitigation
[Technical risk] L/M/H CRITICAL/HIGH/MEDIUM [Calculated] [Mitigation strategy]

Risk scoring: Probability × Impact = Score

  • Low × Critical = HIGH
  • Medium × Critical = HIGH
  • High × Critical = CRITICAL

Examples from banking-walkthrough.md

STRIDE — Payment API:

  • Info Disclosure (IDOR): Customer accesses another customer's transactions — CRITICAL — mitigated by strict account ownership check at repository layer (not controller — prevents bypass)
  • DoS: Request flood on payment endpoint — HIGH — mitigated by rate limiting (per account + per IP) + circuit breaker

Technical Risks:

  • Card network timeout mid-authorization — Medium probability × CRITICAL impact — mitigated by Saga with compensation + idempotency keys + Outbox pattern
  • PostgreSQL primary failure — Low probability × CRITICAL impact — mitigated by synchronous multi-AZ replication + Patroni HA + RTO ≤30s

Gate rule

No CRITICAL risk may remain unmitigated. If a CRITICAL risk has no mitigation, it blocks Phase 4.

All HIGH risks must have at least a documented mitigation strategy (implementation can be deferred, but the strategy must exist).

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.

phase-3-risks is a skill published in the GitHub repository exchanet/method_enterprise_builder_planning (2 stars, last pushed 8mo ago), licensed MIT. It adds 22 tokens to every session and 627 once invoked, about $0.0001 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.
