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 | $0.00024 | $0.00486 |
| Opus 5 | $0.00012 | $0.00243 |
| Sonnet 5 | $0.00005 | $0.00097 |
| Haiku 4.5 | $0.00002 | $0.00049 |
Grade A, and why
skill-product-backlog-prioritization 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 5d 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
Backlog Prioritization (WSJF)
1. Objective
To prioritize features scientifically using Weighted Shortest Job First (WSJF).
2. Logic Locker (CRITICAL)
[!IMPORTANT] FORBIDDEN ACTION: You are strictly forbidden from calculating WSJF scores manually or mentally. Humans and LLMs are bad at floating point arithmetic. Use the script.
3. Core Tooling
You MUST use the provided Python script to calculate scores and sort the backlog.
How to Prioritize
Run the following command:
python3 [skill_path]/scripts/calculate_wsjf.py --file docs/PRODUCT_BACKLOG.md
Note:
[skill_path]is the path to this skill (e.g..agent/skills/skill-product-backlog-prioritization).
4. Scoring Components
When adding a new item to the Backlog, you must estimate:
- User Value (UV): Relative value to the customer (1-10).
- Time Criticality (TC): Is there a deadline? (1-10).
- Risk Reduction (RR): Does this open new options or fix security? (1-10).
- Job Size (JS): Estimate of effort. Support "T-Shirt Sizes" (XS, S, M, L, XL) or relative fibonacci (1, 2, 3, 5, 8, 13, 20).
- XS / ~1d -> 1
- S / ~2-3d -> 2
- M / ~1w -> 5
- L / ~1m -> 13
- XL / ~2m+ -> 20
Formula (Handled by Script): WSJF = (UV + TC + RR) / Job Size
5. Artifact Standards
See examples/backlog_table_example.md for the correct table format.
The table MUST include all 4 input columns and the WSJF output column.
What ships with it
2 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.

skill-product-backlog-prioritization is a skill published in the GitHub repository MatrixFounder/Agentic-development (5 stars, last pushed yesterday), licensed Apache-2.0. It adds 24 tokens to every session and 486 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 2026-08-31.
