What it does
Code Navigation is an agent skill from ozontech/seq-db. How to navigate and explore Go code in this repo. Use the gopls CLI (definition, references, implementation, callhierarchy, symbols, workspacesymbol) as the PRIMARY way to answer "where is this defined / used / implemented / called". Fall back to Grep/Read only when gopls cannot answer. Invoke when exploring the codebase, tracing a symbol, or answering a "where/who/what-calls" question about Go code.
Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Codebase onboarding. The repository describes itself as: seq-db is a scalable and high-performance database designed for storing and querying logs efficiently. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Codebase onboarding
Example prompts
- “where is this defined / used / implemented / called”
- “where/who/what-calls”
- “/code-navigation”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.

What it can do on your machine
Read from SKILL.md and the folder at commit 70af159. 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.
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
Code Navigation loads about 837 tokens when it runs. Until then it costs about 106 tokens; SKILL.md has 386 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.

o files**: YAML/proto/Makefile/markdown/`.env` → `Grep`/`Read`.
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.

- How to navigate and explore Go code in this repo. Use the `gopls` CLI (definition, references, implementation, call_hierarchy, symbols, workspace_symbol) as the PRIMARY way to answer "where is this defined / used / implemented / called". Fall back to Grep/Read only when gopls cannot answer. Invoke when exploring the codebase, tracing a symbol, or answering a "where/who/what-calls" question about Go code.
code-navigation
For Go code, navigate with gopls first. It resolves symbols semantically —
across packages, through interfaces, following the type system — which text
search cannot. Grep/Read are the fallback, not the default: reach for them
only when gopls genuinely can't answer (see below). gopls is allowlisted, so
these run without a prompt.
Map the question to a gopls command
Positions are <file>:<line>:<col>, 1-based, with col pointing at the
identifier (or <file>:#<byteoffset>).
| You want to… | Command |
|---|---|
| Find a symbol by name when you don't know where it lives | gopls workspace_symbol <query> |
| List what's declared in a file (outline) | gopls symbols <file> |
| Jump to where a symbol is defined | gopls definition <file>:<line>:<col> |
| See a type/func's signature + doc | gopls definition -markdown <pos> |
| Find every use of a symbol | gopls references <pos> (-d to include the declaration) |
| Find implementations of an interface (or interfaces a type satisfies) | gopls implementation <pos> |
| See callers/callees of a function | gopls call_hierarchy <pos> |
Add -json (on definition) when you want machine-readable output to parse.
Typical flow
- Bootstrap without grepping. The two commands that take a name/file
instead of a position are your entry points:
- Know the name only →
gopls workspace_symbol MetaData→ gives the declaration'sfile:line:col. - Know the file →
gopls symbols path/to/file.go→ outline with positions.
- Know the name only →
- Navigate from that position:
definition/references/implementation/call_hierarchy. - Read the location(s) gopls returns to see the actual code. Finding where
is gopls's job; viewing the span is
Read's.
Show full SKILL.md (151 more words)Show less
When Grep/Read are the right tool (gopls insufficient)
- Non-symbol text: string literals, log messages, error text, struct tags,
config keys, metric names, magic constants →
Grep. - Non-Go files: YAML/proto/Makefile/markdown/
.env→Grep/Read. - Generated or build-excluded code gopls doesn't resolve (e.g. files behind build tags it didn't load).
- gopls returned nothing for a symbol you're sure exists → confirm with
Grep, then retry. - Reading a known span: once a location is in hand,
Readit directly.
Notes
- Point
colat the start of the identifier, not the line start, or the command resolves the wrong (or no) symbol. - This is a Go-navigation policy; for text-shaped searches across the tree (any
language)
Grepremains correct — the rule is "don't grep for something gopls can resolve semantically," not "never grep". - Equivalent structured alternative: the harness
LSPtool (same gopls engine, JSON results, adds split incoming/outgoing calls + hover) — use it instead if you prefer structured output; results are identical.
