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 | $0.00061 | $0.00750 |
| Opus 5.5 | $0.00024 | $0.00300 |
| Sonnet 5.5 | $0.00012 | $0.00150 |
| Haiku 4.5 | $0.00006 | $0.00075 |
Grade A, and why
codexkit-sprint-planning-assistant 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 1mo 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.

Sprint Planning Assistant
Purpose
Turn a groomed backlog into a well-scoped sprint plan with clear commitments, dependencies, and capacity fit.
When to use
- preparing for a sprint planning meeting
- organizing and estimating a batch of backlog items
- checking if proposed sprint scope fits team capacity
- documenting sprint goals and commitments for stakeholders
When not to use
- strategic product planning or roadmapping
- items are not groomed (requirements unclear, no acceptance criteria)
- portfolio-level work intake or project governance
Inputs
- backlog items (titles, descriptions, acceptance criteria)
- team capacity (available person-days, holidays, known absences)
- sprint duration (typically 1 or 2 weeks)
- velocity reference (last 3 sprints if available)
- known dependencies or blockers
- sprint goal or theme from product owner
Procedure
- Review backlog items and confirm each has clear acceptance criteria.
- Flag items that are too large for one sprint and recommend splitting.
- Estimate effort using story points or T-shirt sizing.
- Map total estimated effort against team capacity and historical velocity.
- Identify cross-team or technical dependencies.
- Recommend a sprint commitment — items that fit capacity with 20% buffer.
- Write the sprint goal as one sentence.
- Produce a sprint summary table for stakeholders.
Output
- sprint goal statement
- committed items table (item, estimate, owner, dependency)
- stretch items (if capacity allows)
- flagged risks or blockers
- capacity utilization summary
Definition of done
- total committed effort is ≤ 80% of team capacity
- every committed item has an owner
- dependencies are explicitly called out
- sprint goal is one clear sentence tied to business value
Examples
- "Plan Sprint 12 with these 15 backlog items for a 5-person team over 2 weeks."
- "Check if we can fit the payment feature plus 3 bug fixes into next sprint."
- "Write a sprint summary for stakeholders — what we're committing to and why."
What ships with it
4 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.
