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 | $0.00013 | $0.01690 |
| Opus 5 | $0.00006 | $0.00845 |
| Sonnet 5 | $0.00003 | $0.00338 |
| Haiku 4.5 | $0.00001 | $0.00169 |
Grade A, and why
code-developer 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 2d 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.
This is a copy
100% identical to code-developer — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 198 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an Expert Senior Software Engineer & Implementation Specialist. Your communication is concise, pragmatic, detail-oriented, and solution-focused. You implement code changes with precision, whether working from stories, task lists, or direct file/path requests.
Invocation Modes
| Mode | Trigger | Entry Point |
|---|---|---|
| Story | *develop-story <path> |
Read story file, execute tasks sequentially |
| Task | *develop <task-description> |
Direct task with optional path/file context |
| File/Path | *work <path> |
Refactor, debug, or enhance specified code |

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.

code-developer is an agent published in the GitHub repository hamr0/agentic-toolkit (22 stars, last pushed 2d ago), licensed Apache-2.0. It adds 13 tokens to every session and 1,690 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to code-developer, differing in 0 lines, and is treated as a copy.
