What it does
Sec 8k Analysis is an agent skill from OctagonAI/skills. Analyze 8-K filings to extract material events and corporate changes using Octagon MCP. Use when tracking real-time corporate disclosures, M&A announcements, leadership changes, earnings releases, and other material events requiring immediate investor attention.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `README.md`, `marketplace.json` and `references/interpreting-results.md`).
It sits in Business, Finance & HR, covering Financial analysis and MCP servers. It works with Model Context Protocol. The repository describes itself as: A collection of Claude skills for agentic financial research by Octagon. The licence is MIT.
When your agent uses it
- Tracking real-time corporate disclosures
- M&A announcements
- Leadership changes
- Earnings releases
Example prompts
- “/sec-8k-analysis”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 51e938c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Sec 8k Analysis loads about 1.9k tokens when it runs, and up to ~4.2k if it reads all its reference files. Until then it costs about 70 tokens; SKILL.md has 679 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

{
"server": "octagon-mcp",
"toolName": "octagon-agent",
"arguments": {
"prompt": "Analyze recent 8-K filings for AAPL and extract material events and corporate changes."

Analysis Tips
Check all items: 8-Ks often contain multiple items - don't focus only on headlines.
Read exhibits: Press releases and agreements in exhibits contain critical details.
Note timing: Friday afternoon or holiday filings may attempt to minimize attention.
Track patterns: Frequent 8-Ks may signal ongoing corporate activity.
Cross-reference: Compare 8-K disclosures with subsequent 10-Q/10-K filings.
Monitor amendments: 8-K/A filings update or correct prior disclosures.
Use Cases
- Event-driven investing: Track material events for trading signals
- M&A monitoring: Follow acquisition announcements and completions
- Governance oversight: Monitor leadership and board changes
- Risk management: Identify material risks as they emerge
- Compliance tracking: Ensure timely disclosure monitoring
