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 | $0.00058 | $0.00300 |
| Opus 5 | $0.00029 | $0.00150 |
| Sonnet 5 | $0.00012 | $0.00060 |
| Haiku 4.5 | $0.00006 | $0.00030 |
Grade A, and why
feature-delivery 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 12d 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
Use this skill when implementing or expanding a feature in PetSwipe.
Workflow
- Inspect the affected area before proposing structure.
- Decide whether the task is frontend-only, backend-only, infra-only, docs-only, or cross-cutting.
- Keep the change coherent across code, navigation, API behavior, validation, and docs.
- Validate with the smallest reliable command set for the touched area.
- Update docs when the task changes user-visible behavior, APIs, or deployment posture.
Delegation
If the task is broad, spawn the matching specialist agent:
frontend_uxbackend_apiinfra_auditordocs_curatorreviewer
PetSwipe Rules
- Frontend work should preserve the Next.js Pages Router structure.
- Backend work should keep routes, controllers, services, entities, and docs aligned.
- Infra work should be validated with render and preflight commands, not claimed complete on inspection alone.
- Doc updates should be made in the same task when behavior changes.
Read references/repo-map.md for structure and references/validation.md for command guidance.
What ships with it
3 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.

feature-delivery is a skill published in the GitHub repository hoangsonww/PetSwipe-Match-App (26 stars, last pushed 4d ago), licensed MIT. It adds 58 tokens to every session and 300 once invoked, about $0.0003 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.
