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 5.1 | $0.00049 | $0.00695 |
| Opus 5 | $0.00024 | $0.00347 |
| Sonnet 5 | $0.00010 | $0.00139 |
| Haiku 4.5 | $0.00005 | $0.00069 |
Grade A, and why
overcast-skill-creator 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 6d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
overcast-skill-creator
Use this when the user wants a focused skill built on Overcast instead of the
broad overcast skill. Example requests: "make an Overcast skill for analyzing
security camera clips", "create a skill that monitors a target and briefs me",
or "turn this Overcast workflow into an installable agent skill".
Reference the broad overcast skill and its
overcast/reference/verbs.md man pages for exact flags. Do not duplicate the
full verb reference.
Design Rules
- Pick one case lifecycle: initialize/setup, gather or sense evidence, add notes/findings, ask/brief, then export.
- Choose the minimum verbs needed. Prefer
case setup,watch,listen,see,face,scan,capture,monitor,note,finding,ask, andbriefonly when they serve the workflow. - Preserve citations. Evidence claims should cite
record.idplusmedia.atwhen a timestamp or range exists. - Prefer
askandbriefover raw JSON spelunking for synthesis. Use raw records for verification and exact fields, not as the default reading path. - For large
watchcontent orlistentranscripts, usecase memory get <record-id> --field <field> --offset <n> --limit <n>rather than head/tail reads of JSONL. - State setup assumptions:
overcast doctor, provider credentials, systemffmpeg/ffprobe, tinycloud version, and whether the workflow needs live sources or only local files.
Template
---
name: overcast-<workflow-name>
description: >-
<One sentence about when an agent should use this focused Overcast workflow.>
---
# overcast-<workflow-name>
Use this skill when <trigger conditions>.
## Quickstart
```bash
overcast doctor --json
overcast case init --json
overcast case setup --target "<target>" --yes --json
overcast <gather-or-sense-verb> <input> --json
overcast ask "<question>" --json
overcast brief --export ./brief.md --json
```
## Evidence Rules
- Cite `record.id` and `media.at` for every media-derived claim.
- Record human observations with `note --ref <record-id> --at <time-range>`.
- Separate observed facts, inferred expected behavior, and open questions.
## Failure Handling
- Run `overcast doctor --json` when a provider or system dependency fails.
- If a record field is large, page it with `case memory get`.
- If a source is unavailable, report the missing source and continue with local
case evidence.
## Validation
```bash
overcast commands --json
overcast <main-verb> --help
overcast ask "<workflow-specific verification question>" --json
```
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.

overcast-skill-creator is a skill published in the GitHub repository kdr/overcast (16 stars, last pushed 2d ago), licensed Apache-2.0. It adds 49 tokens to every session and 695 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 2026-08-30.
