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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Prompt Injection · line 28 Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
What it costs to keep this loaded
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 | $0.00031 | $0.01024 |
| Opus 5 | $0.00015 | $0.00512 |
| Sonnet 5 | $0.00006 | $0.00205 |
| Haiku 4.5 | $0.00003 | $0.00102 |
Grade A, and why
aiwg-regenerate-codex 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 9d 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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Regenerate Codex Context
Regenerate the Codex context file (CODEX.md or ~/.codex/instructions.md) for OpenAI Codex integration. Performs an intelligent merge — preserving team-written content while updating AIWG context.
Core Principle
Team content is preserved. AIWG content is updated. Full injection used (Codex does not support @-link directives).
Important: No @-Link Support
Codex context files do not support @filename style includes. AIWG content is embedded directly using injection markers:
<!-- BEGIN AIWG -->
[AIWG content]
<!-- END AIWG -->
This is different from other providers that use the hook file approach.
Parameters
| Flag | Description |
|---|---|
--no-backup |
Skip creating backup file |
--dry-run |
Preview changes without writing |
--user-level |
Update ~/.codex/instructions.md instead of project-level CODEX.md |
--migrate |
Extract injection to AIWG-codex.md and reference from CODEX.md (future-proofing) |
Context File Locations
| Scope | Path | Use case |
|---|---|---|
| Project-level | CODEX.md |
Project-specific AIWG context |
| User-level | ~/.codex/instructions.md |
User-wide context across all projects |
Default: project-level CODEX.md. Use --user-level for user-wide context.
Execution Steps
Step 1: Create Backup
Unless --no-backup specified, create CODEX.md.backup-{YYYYMMDD-HHMMSS}.
Step 2: Analyze Existing Content
Read CODEX.md if it exists and categorize:
- Team content (PRESERVE): Project rules, conventions, business logic, above or below AIWG block
- AIWG content (UPDATE): Content between
<!-- BEGIN AIWG -->and<!-- END AIWG -->
Step 3: Generate AIWG Content
Generate AIWG content from installed framework manifests. Same content as other providers' hook files, but embedded inline.
Also write AIWG-codex.md as a side file for reference and for potential future migration if Codex adds @-link support.
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.

aiwg-regenerate-codex is a skill published in the GitHub repository jmagly/aiwg (211 stars, last pushed yesterday), licensed MIT. It adds 31 tokens to every session and 1,024 once invoked, about $0.0002 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 2026-09-03.

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…
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"…
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.
