What is activity-brief?

An automated testing agent for NPM projects, which are JavaScript or TypeScript projects managed with NPM.

Use it to audit coverage, create tests and test configuration, validate GitHub Actions, run tests locally, and fix detected errors.

It finds missing tests and testing setup, checks continuous integration workflows, and investigates test failures through repeated test-and-fix cycles.

Token cost

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	$0.00044	$0.00809
Opus 5	$0.00022	$0.00404
Sonnet 5	$0.00009	$0.00162
Haiku 4.5	$0.00004	$0.00081

Security

Grade A, and why

activity-brief 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Activity Brief

Produce a clean recent-activity briefing for the user's current or specified fantasy league.

Scope and data rules

Fantasy league data must come from Flaim MCP tools.
Use web search to enrich player news, injuries, role changes, and schedule context.

Arguments

$ARGUMENTS is the requested number of days back.
If no argument is provided, default to 2.
Treat non-numeric arguments as no argument unless the user clearly explains a different time window in natural language.

Workflow

1. Resolve the target league

Reuse a usable successful get_user_session result from this chat. Call it if that context is missing, after a successful league refresh, or when the user confirms account, connection, league-list, or default changes. Do not repeat it just for a follow-up or a switch to another league already in the session result. Follow the tool's error guidance if a lookup fails.
If the user explicitly names a league, platform, or sport, honor that.
Otherwise treat this as a vague singular request: use defaultLeague when present, otherwise the relevant sport entry in defaultLeagues.
If there is no applicable default and multiple leagues still match, ask which league.
Call get_league_info for the selected league before interpreting transactions so team names and owner/team mapping are resolved.

2. Pull recent transactions

For daily or 24-hour briefs, call get_transactions with the default count or explicit count: 25.
Use a larger count such as count: 40 only when the requested window is busier or longer than a normal daily brief.
Do not use count: 100 unless the user asks for an exhaustive or full-week activity audit.
Retrieve the recent transaction window the platform provides, then trim the presentation to the requested day range.
Remember platform caveats:
- Yahoo ignores explicit week and uses a recent timestamp window.
- ESPN and Sleeper are more week-oriented than date-oriented.

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.

activity-brief is a skill published in the GitHub repository jdguggs10/flaim (17 stars, last pushed 2d ago), licensed MIT. It adds 44 tokens to every session and 809 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.
