Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00036 | $0.00692 |
| Opus 5 | $0.00018 | $0.00346 |
| Sonnet 5 | $0.00007 | $0.00138 |
| Haiku 4.5 | $0.00004 | $0.00069 |
Grade A, and why
last30days 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 10d 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
last30days (open variant): Research + Watchlist + Briefings
Multi-mode research skill with persistent knowledge accumulation.
Command Routing
Parse the user's first argument to determine the mode:
| First word | Mode | Reference |
|---|---|---|
watch |
Watchlist management | references/watchlist.md |
briefing |
Morning briefing | references/briefing.md |
history |
Query accumulated knowledge | references/history.md |
| (anything else) | One-shot research | references/research.md |

Load Context
At session start, read ${SKILL_ROOT}/variants/open/context.md for user preferences and source quality notes. Update it after interactions.

Routing Logic
After determining the mode, read the corresponding reference file using the Read tool:
What ships with it
5 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.
- 10d ago First seen · 78 lines · 36 tokens per session scan A 5e45073f2a90
last30days is a skill published in the GitHub repository hardikpandya/last-30-days (9 stars, last pushed 6mo ago), licensed MIT. It adds 36 tokens to every session and 692 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.
