mellea-fy-map

mellea-fy-map is a skill for Claude Code, Codex from generative-computing/mellea-skills-compiler. It costs 20 tokens per session (2,328 once invoked), scanned A, original, Apache-2.0.

An element-mapping step for a workflow that converts an agent skill description into a typed Python package. It routes each identified element to a package file, symbol, and Mellea building block.

In plain words
What is it for?
Use it after classification and inventory to decide where extracted data, classifications, generated content, validation rules, and other elements belong in the package.
Why use it?
It turns a tagged inventory into an implementation plan, while leaving tool-dependent choices for a later dependency step.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Token cost

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.

Security

Grade A, and why

mellea-fy-map 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.

Melleafy Step 2: Element-to-Primitive Mapping

Version: 4.1.0 | Prereq: inventory.json, classification.json | Produces: element_mapping.json

Schema: Output intermediate/element_mapping.json MUST conform to schemas/element_mapping.schema.json.

Step 2 reads inventory.json and produces element_mapping.json — the routing decision for every element: which file in the generated package, which symbol, which Mellea primitive.

Important: Step 2 does NOT commit dispositions for tool-dependent elements. Every TOOL_TEMPLATE mapping entry is provisional (final_target_file: "pending_step_2.5"). Step 2.5 decides real_impl vs stub vs mock and amends.

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.
