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 | $0.00027 | $0.03163 |
| Opus 5 | $0.00014 | $0.01581 |
| Sonnet 5 | $0.00005 | $0.00633 |
| Haiku 4.5 | $0.00003 | $0.00316 |
Grade A, and why
mellea-fy-inventory 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 10d 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 — 182 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Melleafy Steps 1a + 1b: File Inventory and Element Tagging
Version: 4.1.0 | Prereq: classification.json | Produces: inventory.json
Schema: Output
intermediate/inventory.jsonMUST conform toschemas/inventory.schema.json.
Step 1a reads files from the source based on the detected runtime's dialect. Step 1b takes those files and produces inventory.json — every significant element tagged with one of 17 tags and assigned to one of 9 dependency categories.
Step 1a: File Inventory
Read source files per the runtime's dialect. The dialect doc at docs/dialects/<runtime>.md defines exactly which files to read and their roles.
| Runtime | Primary files | Roles |
|---|---|---|
openclaw |
SOUL.md, AGENTS.md, SETUP.md (opt), *.md companions |
C1 identity, C2 operating rules, C8 runtime env |
bob |
.bob/settings/settings.json, .claude/skills/*.md, frontmatter files |
C1-C2 per frontmatter; C6 for tool |
claude_code |
CLAUDE.md, .claude/commands/*.md, frontmatter files |
C1-C2 per frontmatter; C6 for tool declarations |

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

mellea-fy-inventory is a skill published in the GitHub repository generative-computing/mellea-skills-compiler (49 stars, last pushed 3d ago), licensed Apache-2.0. It adds 27 tokens to every session and 3,163 once invoked, about $0.0001 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.
