What is phoenix-final-gate?

A final security review step for deciding whether a Phoenix feature specification is ready to ship. It checks required security evidence and blocks release when critical issues remain.

Use it to make a documented SHIP or NO-SHIP decision after the earlier specification steps, and to flag softer concerns such as missing metrics or regulatory details.

It prevents unclear requirements, missing proof, tenant-data exposure, weak authentication, and unsafe AI behaviour from reaching implementation.

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.

Any agent

npx skills add Security-Phoenix-demo/security-skills-claude-code --skill phoenix-final-gate

Clone the repo

git clone --depth 1 https://github.com/Security-Phoenix-demo/security-skills-claude-code

Made for: Claude Code.

Or install phoenix-prd-pipeline, the plugin that ships this one along with the rest of its 13 skills.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00198	$0.00951
Opus 5	$0.00099	$0.00476
Sonnet 5	$0.00040	$0.00190
Haiku 4.5	$0.00020	$0.00095

Security

Grade A, and why

phoenix-final-gate 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 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.

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.

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Phoenix Security — Final Gate Reviewer (Role 10)

Token Budget: ≤800 tokens Depends On: All previous roles (01–09) Feeds Into: FEATURE_SPEC.md + Confluence push (if SHIP) Output: 10-final-gate.md

Hard Blockers (any = NO_SHIP)

Run this checklist explicitly — do not skip any item:

Critical ambiguities remaining (Role 05) > 0
Any MUST lacks proof path (Role 08, unverified_musts > 0 without downgrade rationale)
PSC-03 multi-tenancy not addressed in security requirements
PSC-06 auth layer not addressed for any new endpoint
PSC-08 AI agent autonomous action not gated (if LLM in scope)
Scope creep: requirements outside SCOPE_DEFINITION from Role 02
P0 security requirements NOT in Batch 1 (Role 09)
Active enterprise account requirements (Mimecast/JM/Anaplan) not covered at P0

Soft Warnings (flag, do not block)

Manual-only proof paths for non-security requirements
Missing success metrics vs Phoenix case study benchmarks
Batch count implies >4 weeks without CTO sign-off
Regulatory hooks not documented
Competitor brand names in user-facing copy

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.

phoenix-final-gate is a skill published in the GitHub repository Security-Phoenix-demo/security-skills-claude-code (70 stars, last pushed yesterday), licensed MIT. It adds 198 tokens to every session and 951 once invoked, about $0.0010 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 2026-09-11.
