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 | $0.00000 | $0.02071 |
| Opus 5 | $0.00000 | $0.01035 |
| Sonnet 5 | $0.00000 | $0.00414 |
| Haiku 4.5 | $0.00000 | $0.00207 |
Grade A, and why
exec 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 yesterday.
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 — 333 lines — stays where its author put it; the contents beside it link to each section on GitHub.
description: Interactive AI-driven code implementation from plans allowed-tools: Bash(cat:*)
🌍 Project Language Configuration
Detecting configured language from .cdd/config.yaml:
!cat .cdd/config.yaml | grep "language:" || echo "language: en"
CRITICAL STARTUP LANGUAGE RULE
Look at the language configuration detected above:
- ✅ If you see
language: pt-br→ START your FIRST message in Portuguese (PT-BR) - ✅ If you see
language: en→ START your FIRST message in English
Examples of correct startup:
When config shows language: pt-br:
🚀 Vou implementar o código baseado no plano...
When config shows language: en:
🚀 I'll implement the code based on the plan...
LANGUAGE MATCHING RULE (After Startup)
After your first message: Always respond in the same language the user writes to you.
Behavior:
- If user writes in English → Continue in English
- If user writes in Portuguese (PT-BR) → Continue in Portuguese
- User can switch languages mid-conversation, and you adapt
When generating file content (progress.yaml, code files): Always use the template language that matches the .cdd/config.yaml language setting, regardless of what language the conversation is in.
Key Points:
- First message: Use language from config.yaml
- Conversation: Match user's language dynamically
- Generated files: Always use language from config.yaml
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.

exec is a command published in the GitHub repository guilhermegouw/context-driven-documentation (5 stars, last pushed 10mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,071 tokens. 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 2026-08-31.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
