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 | $0.00106 | $0.01485 |
| Opus 5 | $0.00053 | $0.00743 |
| Sonnet 5 | $0.00021 | $0.00297 |
| Haiku 4.5 | $0.00011 | $0.00148 |
Grade A, and why
brief-intake 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 7d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
brief-intake
You help the user (or the next skill in the chain) absorb raw unstructured input and emit a clean, structured brief shaped for whatever artifact comes next. This skill is the upstream collector — every other skilldrop generator opens with "Gather the essentials"; this is the skill that does the gathering once, so downstream skills can skip straight to drafting.
How to respond
-
Identify the downstream target. Ask if the user hasn't said: "What are you going to do with this brief?" Map the answer to one of:
Downstream skill Trigger phrases adr-generator"ADR", "decision record", "capture a decision", "we decided X" design-doc"design doc", "tech proposal", "one-pager for review", "RFC" runbook-generator"runbook", "on-call doc", "operational doc", "prod-readiness" tech-comparison-matrix"compare X vs Y", "vendor selection", "tech selection" exec-summary"exec summary", "1-pager for the VP", "board update" deck-builder/slide-outliner"deck", "slides", "presentation", "pitch", "review meeting" decision-log"decisions and action items", "follow-ups from the meeting" (generic) None of the above — emit the generic brief and let the user pick later -
Ingest the source. The user will paste text, give a file path, or describe verbally. If the source is huge (>3000 words), tell them you're going to extract the load-bearing parts and skip the rest, then confirm scope before you start.
-
Extract once, into the target's shape. Each downstream skill needs a specific set of fields. Use the matching template:
templates/brief-adr.md— context · forcing function · options · chosen option · trade-offstemplates/brief-design-doc.md— what · who · why now · constraints · open questionstemplates/brief-runbook.md— service · owners · stack · deployment surface · known failure modestemplates/brief-tech-comparison.md— question · candidates · evaluation criteria · constraintstemplates/brief-exec-summary.md— ask · audience · business impact · what you needtemplates/brief-deck.md— topic · audience · time budget · key messages · palette/brandtemplates/brief-decision-log.md— source · scope · today's datetemplates/brief-generic.md— fallback when target is unknown

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.

brief-intake is a skill published in the GitHub repository sananthanarayan/skilldrop (2 stars, last pushed 23d ago), licensed MIT. It adds 106 tokens to every session and 1,485 once invoked, about $0.0005 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.
