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 | $0.02182 |
| Opus 5 | $0.00012 | $0.01091 |
| Sonnet 5 | $0.00005 | $0.00436 |
| Haiku 4.5 | $0.00002 | $0.00218 |
Grade A, and why
issue 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Kit Preamble — issue
Kit Script Root
Kit root: ${CLAUDE_PLUGIN_ROOT}
- Absolute path above → plugin install (substituted at load time; no project
scripts/dir): prefix every kit script command with it, e.g.bash <kit-root>/scripts/checkpoint.sh …. Absolute paths also work from worktrees. - Literal
${…}placeholder above → standalone layout: run commands as written.
Project Context Detection
Run these checks silently at the start. Use results to adapt behavior:
[ -f issues.md ]— if true, this project uses the sprint system. Respect issue numbering and STATUS.md.[ -f docs/sprint_state.md ]— if true and Status showsrunning, a sprint is active. Be aware of parallel work in worktrees.[ -f docs/prd_digest.md ]— if true, read it for quick project context before starting.
Kit Rules
- Verify
gh auth statusbefore any GitHub operation.
Algorithm
Phase 1 — Context Gathering
- Read
$ARGUMENTS. If empty, ask the user for a description and stop. - Read
issues.md. If not found, tell the user to run/kickofffirst and stop. - Parse the highest issue number from
issues.mdusing### ISSUE-(\d+):regex. Next issue number = max + 1. - Read the following docs in parallel (skip any that don't exist):
docs/prd_digest.mddocs/requirements.mddocs/ux_spec.mddocs/architecture.mddocs/data_model.mddocs/test_plan.mddocs/design_philosophy.mddocs/design_system.mddocs/wireframes.mddocs/interactions.mddocs/copy_guide.md
If none of the planning docs exist, warn the user but proceed with issues.md + STATUS.md only.
4.5) Set design context flag:
has_design_docs=trueif bothdocs/design_philosophy.mdanddocs/wireframes.mdexist;falseotherwise.- This flag controls whether design doc updates are offered in Phase 2.
Phase 2 — Doc Update Detection & Scope Estimation
What ships with it
1 file 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.

issue is a skill published in the GitHub repository pillip/claude-dev-kit (11 stars, last pushed 16d ago), licensed MIT. It adds 24 tokens to every session and 2,182 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.
