What is gosymdb AGENTS.md?

Repository instructions for gosymdb, a Go code database that records definitions, relationships, and call paths in SQLite. Go is a programming language, and a call graph shows which functions call other functions.

Finding symbols, locating definitions and references, tracing callers and callees, checking interface implementations, measuring change impact, and finding unused symbols.

They explain how to find the database and how to query code relationships, reducing the need to inspect a large Go project manually.

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	$0.00867	$0.00867
Opus 5.5	$0.00347	$0.00347

Security

Grade A, and why

gosymdb AGENTS.md 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 2mo 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.

What gosymdb is

gosymdb is a Go-specific symbol and call-graph database backed by SQLite. It uses Go's own type-checker (go/packages, go/types) to build a persistent index of one or more Go modules, then answers structured queries:

find — search symbols by name, package, file, or kind
def — exact single-symbol lookup
callers / callees — direct or transitive call edges
blast-radius — full transitive impact (with test/prod split)
dead — symbols with no callers
implementors — interface ↔ type satisfaction
references — where a type appears (assertions, switches, literals, conversions)
packages, health, agent-context, version — meta queries

Every query supports --json for structured output. The full API is enumerated in one shot by gosymdb agent-context, which prints a JSON document with command signatures, flags, env block, and parsing notes.

How the database is found

gosymdb walks parent directories looking for gosymdb.sqlite, the same way Go tools walk for go.mod. Pass --db <path> to override. If no database is found, commands return error_code: no_database with a hint to run gosymdb index --root <module> first.

The freshness loop

The index goes stale the moment source files change. Every JSON response carries an env.stale_packages array listing packages whose source has drifted from what's indexed. The check uses a git fast-path (one git diff against the commit stamped at index time) with a per-file FNV-64a hash fallback when git isn't usable.

Pass --auto-reindex to any query command to re-index stale modules in place before the query runs. The check itself is cheap enough to run on every call (sub-second on Kubernetes-scale codebases).

MCP integration

gosymdb exposes gosymdb cli-bridge-manifest — a single subcommand that prints the canonical cli-bridge spec for this binary. When cli-bridge is installed and gosymdb's spec is registered, each command becomes an MCP tool named gosymdb_<command> (e.g. gosymdb_callers, gosymdb_blast_radius). Setup steps are in the main README's MCP section.

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.
