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 | $0.00037 | $0.02344 |
| Opus 5 | $0.00018 | $0.01172 |
| Sonnet 5 | $0.00007 | $0.00469 |
| Haiku 4.5 | $0.00004 | $0.00234 |
Grade A, and why
transform 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.
How it starts
The opening of the file, as written. The whole thing — 325 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Intent
Transform data from one format or schema to another while tracking what information is preserved, modified, or lost during conversion. Ensure output conforms to target schema with full provenance.
Success criteria:
- Output conforms to target schema
- All fields mapped correctly or explicitly marked as lost
- Transformation is deterministic and reproducible
- Loss/distortion explicitly documented
- Evidence anchors trace source to output
Compatible schemas:
schemas/output_schema.yaml
Inputs
| Parameter | Required | Type | Description |
|---|---|---|---|
source |
Yes | string or object | Input data to transform |
target_schema |
Yes | string or object | Schema or format specification for output |
mapping |
No | object | Explicit field mappings (source -> target) |
preserve_unknown |
No | boolean | Keep fields not in mapping (default: false) |
strict |
No | boolean | Fail on any mapping ambiguity (default: false) |
default_values |
No | object | Defaults for missing required fields |
Procedure
-
Parse source data: Load and validate input
- Identify source format (JSON, YAML, XML, CSV, etc.)
- Parse into internal representation
- Detect encoding and special characters
- Record source structure for provenance
-
Analyze target schema: Understand destination requirements
- Load target schema specification
- Identify required vs optional fields
- Note type constraints and validations
- Map nested structures
-
Build transformation map: Match source to target
- Apply explicit mappings if provided
- Infer mappings for matching field names
- Identify fields requiring type conversion
- Flag unmappable source fields
-
Execute transformation: Apply mappings
- Transform each field according to mapping
- Apply type conversions (string to number, etc.)
- Handle nested objects recursively
- Apply default values for missing required fields
What ships with it
2 files 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.

transform is a skill published in the GitHub repository synaptiai/agent-capability-standard (4 stars, last pushed 3d ago), licensed Apache-2.0. It adds 37 tokens to every session and 2,344 once invoked, about $0.0002 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 2026-08-31.
