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 | $0.00038 | $0.02265 |
| Opus 5 | $0.00019 | $0.01132 |
| Sonnet 5 | $0.00008 | $0.00453 |
| Haiku 4.5 | $0.00004 | $0.00227 |
Grade A, and why
retrieve 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 4d 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 — 333 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Intent
Execute retrieve to fetch specific, known information from specified sources. Unlike search (which explores under uncertainty), retrieve fetches identified items with full provenance tracking.
Success criteria:
- Requested data is fetched completely
- Source and timestamp are recorded
- Data integrity is verified where possible
- Citations enable re-retrieval
- Missing data is explicitly flagged
World Modeling Context:
Retrieve feeds into all world modeling layers by providing grounded observations for world-state, timestamps for temporal-reasoning, and evidence for grounding.
Compatible schemas:
schemas/output_schema.yaml
Inputs
| Parameter | Required | Type | Description |
|---|---|---|---|
target |
Yes | string|object | What to retrieve (path, URL, query, or identifier) |
source |
No | string | Where to retrieve from (file, api, database); default: infer |
format |
No | string | Expected format (json, text, binary); default: auto-detect |
constraints |
No | object | Filters, projections, version specifications |
Procedure
-
Identify target: Determine exactly what to fetch
- File path: Exact file location
- URL: Web resource address
- API endpoint: Service + parameters
- Record: Database/system identifier
-
Verify source accessibility: Confirm retrieval is possible
- Check permissions
- Verify network access if remote
- Confirm source exists
-
Execute retrieval: Fetch the data
- For files: Read with line numbers preserved
- For URLs: Fetch with timeout and retry
- For APIs: Call with appropriate auth
- Record exact timestamp of retrieval
-
Validate retrieved data: Check completeness and integrity
- Verify format matches expected
- Check for truncation or corruption
- Validate against schema if available
- Compute hash for integrity tracking
-
Extract relevant portions: If constraints specified
- Apply filters to reduce data
- Project specific fields
- Slice by line numbers or sections
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.

retrieve is a skill published in the GitHub repository synaptiai/agent-capability-standard (4 stars, last pushed 4d ago), licensed Apache-2.0. It adds 38 tokens to every session and 2,265 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.
