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.

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 | $0.00012 | $0.00388 |
| Opus 5 | $0.00006 | $0.00194 |
| Sonnet 5 | $0.00002 | $0.00078 |
| Haiku 4.5 | $0.00001 | $0.00039 |
Grade A, and why
final-client-handoff 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 3d 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.
What it actually says
Final Client Handoff
Use this skill to give the user a calm, accurate closeout they can trust and act on.
Closeout modes
For a small change, report changed files, actual checks and remaining limits; no release manifest is required. For a client release, aggregate existing applicable ownership, tested/untested, recovery and release evidence using the full procedure below.
Workflow
- Inspect the affected surface, relevant project scripts, target URL and available inspection tooling; reuse existing context.
- Read Final Client Handoff Guide before claiming the site is ready.
- Run the narrowest meaningful checks for the risk: visual, mobile, accessibility, performance, forms, media, SEO, analytics, deployment, or handoff.
- Fix issues when they are in scope; otherwise record exact evidence and remaining risk.
- Summarize commands, URLs, screenshots/checks, changed files, and what was not tested.
For a full client release, use references/release-handoff-template.md for the release, monitoring, recovery, and ownership record. Validate it with python3 "<skill-root>/scripts/verify-handoff.py" <handoff.json>.
Scoped execution
Apply the shared web contract once when execution crosses phases; reuse it if already read. Load only the specialist guidance relevant to the requested surface and deliverable.
For helper-driven evidence, use the typed record schema. The helper validates structure only; use actual inspection/test results for claims.
Resolve <skill-root> to this skill folder's actual absolute location; preserve project-local module resolution for Node capture tools.
What ships with it
5 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.

final-client-handoff is a skill published in the GitHub repository TheGoat395/Codex-Skills (122 stars, last pushed yesterday), licensed MIT. It adds 12 tokens to every session and 388 once invoked, about $0.0001 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.
