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.

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 | $0.00055 | $0.01045 |
| Opus 5.5 | $0.00022 | $0.00418 |
| Sonnet 5.5 | $0.00011 | $0.00209 |
| Haiku 4.5 | $0.00006 | $0.00104 |
Grade A, and why
codd-init 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.
How it starts
The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CoDD Init
Initialize CoDD in the current project, then move immediately into the first scan and validation cycle so the dependency graph starts from a clean baseline.
Usage
Run this skill when a repository does not have a codd/ directory yet and you need to bootstrap CoDD with the official codd CLI entry point.
Instructions
-
Preflight before running
codd init:- Work from the project root where
codd/should be created. - If
codd/already exists, do not re-run init. Inspect the existing CoDD setup instead. - If the
coddcommand is not available, install the package so the console script is onPATHbefore continuing.
- Work from the project root where
-
Collect the required inputs:
- Project name: default to the current directory name unless the user provides a better product name.
- Primary language: choose one of
python,typescript,java, orgo. - Requirements file (optional): if the user already has a requirements document (any format —
.txt,.md,.doc), use--requirementsto import it. CoDD adds frontmatter automatically.
-
Choose the command:
- With existing requirements file (recommended):
codd init --project-name "<project-name>" --language <language> --requirements <path-to-requirements> --dest .
- Without requirements (user will add them later):
codd init --project-name "<project-name>" --language <language> --dest .
-
Run the selected
codd initcommand. -
Confirm the generated skeleton:
codd/codd.yamlcodd/scan/codd/reports/codd/.gitignore.codd_version
-
For an existing project, handle the bootstrap carefully:
- Do not assume old design docs already have CoDD frontmatter. Inspect them before the first scan.
- Prefer adding frontmatter to the documents you want CoDD to track before treating scan results as authoritative.
- Legacy annotation files under
codd/annotations/are optional and backward-compatible. Create them only if the project still uses that workflow.
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.

codd-init is a skill published in the GitHub repository yohey-w/codd-dev (115 stars, last pushed 1mo ago), licensed MIT. It adds 55 tokens to every session and 1,045 once invoked, about $0.0002 per session on Opus 5.5. 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.
