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 | $0.00010 | $0.01347 |
| Opus 5 | $0.00005 | $0.00674 |
| Sonnet 5 | $0.00002 | $0.00269 |
| Haiku 4.5 | $0.00001 | $0.00135 |
Grade A, and why
devkit-create-skill 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 7d 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 — 220 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create AIWG Skill
Create a new skill that can be triggered by natural language patterns.
Understanding Skills
Skills differ from commands:
- Commands: Triggered by explicit
/command-nameinvocation - Skills: Triggered by natural language patterns (e.g., "apply voice", "validate writing")
Skills are ideal for:
- Capabilities users invoke conversationally
- Features that should "just work" without explicit commands
- Cross-cutting concerns that apply in many contexts
Process
1. Validate Parameters
Verify $ARGUMENTS contains:
- Skill name (kebab-case)
--totarget (addon or framework, NOT extension)
Note: Skills cannot be added to extensions because skills need standalone functionality.
Check target exists:
ls ~/.local/share/ai-writing-guide/agentic/code/addons/<target>/
# or
ls ~/.local/share/ai-writing-guide/agentic/code/frameworks/<target>/
2. Interactive Design (if --interactive)
Guide the user through skill design:
Skill Purpose:
What does this skill do? (e.g., "applies voice profiles to content", "validates code quality")
Trigger Phrases:
What natural language phrases should activate this skill? Examples:
- "apply voice", "use voice", "write in voice"
- "validate code", "check quality", "review code"
- "format document", "clean up", "prettify"
Input Requirements:
What input does this skill need?
- Content to process
- Configuration parameters
- File paths
Output Format:
What does this skill produce?
- Transformed content
- Validation report
- Recommendations
Reference Materials:
Does this skill need supporting documentation?
- Style guides
- Validation rules
- Example outputs
3. Execute Scaffolding
Run the CLI scaffolding tool:
node ~/.local/share/ai-writing-guide/tools/scaffolding/add-skill.mjs \
<name> \
--to <target>
4. Generated Structure
<target>/skills/<name>/
├── SKILL.md # Main skill definition
└── references/ # Supporting documentation
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.

devkit-create-skill is a skill published in the GitHub repository jmagly/aiwg (209 stars, last pushed today), licensed MIT. It adds 10 tokens to every session and 1,347 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.

goal-writer
Drafts a goal+rider document pair that briefs an autonomous coding agent on one round of work — a goal file under 4,000 characters (sized to fit the /goal command in both Claude Code and Codex) plus an unbounded rider with phased plans and named depth tests. Use when the user says "draft a goal", "write a goal+rider"…
surge
Use when a user provides a PRD, spec, or detailed requirements document and needs a full project delivered through iterative expert orchestration — multi-round analyze/research/design/implement/QA cycles with convergence detection. NOT for: single-file edits, quick prototypes, simple Q&A, or tasks without a written…
horizon
Run a durable Horizon workflow for a multi-feature goal with bounded autonomous retries and an audit trail.
check-in
Record a Parallax protocol checkpoint with concrete evidence before gated implementation work.
debug
Perform an evidence-based Parallax diagnosis or post-build audit and verify the repair.
hyperplan
Harden a non-trivial plan through a three-round adversarial critique and evidence-based synthesis.
