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 | $0.00021 | $0.00822 |
| Opus 5 | $0.00010 | $0.00411 |
| Sonnet 5 | $0.00004 | $0.00164 |
| Haiku 4.5 | $0.00002 | $0.00082 |
Grade A, and why
devkit-create-extension 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 4d 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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create AIWG Extension
Create a new extension (framework expansion pack) with AI assistance.
Extensions enhance a specific parent framework with additional templates, checklists, and domain-specific content. They cannot operate standalone.
Usage
/devkit-create-extension <name> --for <framework> [--interactive]
Arguments
| Argument | Required | Description |
|---|---|---|
| name | Yes | Extension name (kebab-case recommended) |
Required Options
| Option | Description |
|---|---|
| --for | Parent framework ID (e.g., sdlc-complete, media-marketing-kit) |
Optional Options
| Option | Description |
|---|---|
| --interactive | Enable interactive mode with guided questions |

- Templates: What templates should be included?
- Checklists: What verification checklists are needed?
- Dependencies: Does it depend on other extensions?

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.
- 4d ago First seen · 116 lines · 21 tokens per session scan A a4c6c78d9d10
devkit-create-extension is a skill published in the GitHub repository jmagly/aiwg (208 stars, last pushed yesterday), licensed MIT. It adds 21 tokens to every session and 822 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.
Other skills, from other repositories
hunt
Compose a guided or automatic shift from the ready catalog, then review it first or run it directly under one time budget. Use when the owner wants to choose jobs or let Nightshift find the highest-value applicable work.
archive
File the finished part of the run state into a dated archive — shipped items, research, opportunities, the rotated journal, and handled snags. The live files stay lean; the facts stay on disk.
doctor
Read-only Nightshift diagnosis — workspace, rules, markers, session, process lease, watchman, deadline, and classified next actions. Use when a shift looks wrong, recovery is unclear, or the owner asks what Nightshift sees. Never repairs by being invoked.
import-issues
Stage explicitly selected GitHub issues onto the drafting table as quoted source. Never searches, never writes back to GitHub, never installs gh.
purge
Permanently delete this project's Nightshift state. Does not uninstall the plugin.
stop
Issue a stop-work order — pause the shift immediately, leaving unfinished items open.
