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 | $0.00025 | $0.00265 |
| Opus 5 | $0.00013 | $0.00133 |
| Sonnet 5 | $0.00005 | $0.00053 |
| Haiku 4.5 | $0.00003 | $0.00026 |
Grade A, and why
grade-story-design 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 8d 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
Steps:
1. Read the Analysis JSON
- Read the analysis json document.
2. Grade the Desogm
- grade the analysis based on the User Story Quality Rubric defined in
/rubric.md. - Identify a score for each dimension and provide your reasoning for that score.
- Provide recommendations for improvement for each dimension with an imperfect score.
3. Save the Grade
- save the grade to a new json file with the same name as the design json file, but with the suffix
.design-grade.json. This file must follow the/schema/design-grade.schema.jsonschema.
4. Write the Sentinel File
- create a sentinel file in the
.processdirectory, named{skill-name}.done.json. - the sentinel file will follow @/schema/sentinel.schema.json.
- set the task field to "{skill-name}".
- the verify_params of the sentinel file will follow @/schema/verify-params.schema.json.
- set the verify_params as follows:
- set "design_grade_path" as the path to the design grade file relative to repo root.
What ships with it
28 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.
- 8d ago First seen · 27 lines · 25 tokens per session scan A c9757e79dd1c
grade-story-design is a skill published in the GitHub repository djscheuf/agentic-dev-ecosystem-template (12 stars, last pushed 2d ago), licensed MIT. It adds 25 tokens to every session and 265 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.
