The knowledge base (KB) is your long-term memory. It is a collection of HTML
files at ~/.config/opencode/kb/. Each file records something learned in a
past session — a workflow, a tool behavior, an environment detail, a pattern,
a process — that would otherwise be rediscovered from scratch.
This is not documentation for the user. It is memory for you.
Every agent must load this skill at the start of every session. Read the KB directory listing and build a lightweight mental index:
~/.config/opencode/kb/
For each .html file found, extract from its <head>:
<title> — the entry name<meta name="description"> — a one-line summary<meta name="tags"> — comma-separated topics<meta name="priority"> — high, normal, or low<meta name="updated"> — last updated dateHold this index in mind for the session. Do not load the full HTML content of every file — only fetch specific entries when you actually need them.
Check the updated date of each entry. If any entry has not been updated in
180 days or more, handle the observation according to your role:
"N KB entries haven't been updated in 6+ months: [title1], [title2], ... Worth reviewing when you get a chance."
State or report this once, do not repeat it. Do not delete or alter stale entries merely because of their age.
Before attempting something you might have done before — using a tool, running a workflow, looking something up, interacting with a service — pause and check the index. If a relevant entry exists, read that file first and follow the recorded process.
When multiple entries are relevant, fetch high priority entries before
normal, and normal before low.
When you use a KB entry during work and observe that the recorded behavior does not match reality — a command fails, a path is wrong, or a process has changed — handle it according to your role:
kb-writer to update the entry with the correct
information, noting what changed and why.kb-writer or announce an update to the user.
Report the outdated behavior, observed replacement, evidence, and affected
entry to the primary agent.Do not silently leave incorrect entries in place.
When you discover something non-trivial that would be useful to remember in future sessions, first distinguish project-specific information from durable, cross-project knowledge:
context-capture.kb-writer.Then handle the candidate according to your role:
context-capture with
target: agents_md for broad project facts and conventions, or
target: skill for a focused repeatable workflow. Pass the absolute
project_root and concise content with useful supporting context. For
target: skill, also pass skill_name and skill_description.kb-writer with:
high (frequently needed or critical), normal (default),
or low (edge case or rarely needed)kb-writer or context-capture. Report candidate
global and project-specific learnings to the primary agent with supporting
context so it can classify and route them.The primary agent and ordinary subagents never edit KB files directly. Only the
primary agent delegates creates or updates, and the explicitly delegated
kb-writer is the authorized writer.
Each entry is a valid HTML file. Filename: <slug>.html where the slug is
lowercase, hyphen-separated. Examples: gitlab-mr-diff.html, jira-ticket-lookup.html.
