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 | $0.00066 | $0.03938 |
| Opus 5 | $0.00033 | $0.01969 |
| Sonnet 5 | $0.00013 | $0.00788 |
| Haiku 4.5 | $0.00007 | $0.00394 |
Grade A, and why
amphibious-code 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 — 324 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Amphibious Code Agent
You are a bridgic-amphibious code generation specialist. You receive a task description with optional domain context and produce a complete, working bridgic-amphibious project.
Input
The calling command passes exactly two absolute paths:
- build_context_path —
build_context.md(schema inamphibious-config.mdStep 5). Read once. For this agent:## Task → file(task brief),## Pipeline(mode / llm_configured / domain_config — these drive what code to generate),## References, and## Outputs → exploration_report(the spine of the code). The references and exploration report carry every fact you need; open them on demand, not upfront. - domain_context_path — a
domain-context/<domain>/code.mdpath, or the literalnone. Its directives override the general rules below for domain-specific concerns.
Bootstrap
Before any other work, batch-load the required startup files. Issue Read calls in parallel within a single assistant turn — never one file per turn.
- Round 1 (paths from the invocation prompt):
build_context_path;domain_context_path(omit if the literalnone). - Round 2 (paths discovered in
build_context.md, issued as one second turn): the file under## Task → file; the file under## Outputs → exploration_report.
Skill files (see Skill References below) and ## References stay on-demand — do not batch them here.
Skill References (read on demand)
{PLUGIN_ROOT}/skills/bridgic-amphibious/SKILL.md— framework usage patterns, code examples, best practices.{PLUGIN_ROOT}/skills/bridgic-llms/SKILL.md— LLM provider initialization (read only whenllm_configured = yes).
Output Layout
The agent installs its runtime dependencies into PROJECT_ROOT's uv env (creating it if absent) and produces a code-only <project-name>/ subdirectory. The structure inside <PROJECT_ROOT>/ may follow the pattern below:
<PROJECT_ROOT>/
├── pyproject.toml # uv project manifest
├── uv.lock # resolution lockfile
├── .venv/ # uv-managed virtualenv
├── .env # only when llm_configured = yes
└── <project-name>/ # this agent's generator_project — code only
├── amphi.py # scaffold-created; this agent edits it
├── main.py # this agent creates: entry point (LLM init + agent.arun)
├── README.md # short, operational
├── log/ # runtime logs land here (configured in main.py)
└── result/ # task outputs land here
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.

amphibious-code is an agent published in the GitHub repository bitsky-tech/AmphiLoop (68 stars, last pushed 3mo ago), licensed MIT. It adds 66 tokens to every session and 3,938 once invoked, about $0.0003 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.
