Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00044 | $0.00263 |
| Opus 5.5 | $0.00018 | $0.00105 |
| Sonnet 5.5 | $0.00009 | $0.00053 |
| Haiku 4.5 | $0.00004 | $0.00026 |
Grade A, and why
index 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 1mo 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 it actually says
Index Maintenance
Check health
code-graph-mcp health-check
Rebuild (incremental — only changed files)
code-graph-mcp incremental-index
Full rebuild (when incremental isn't enough)
code-graph-mcp rebuild-index --confirm
This builds the new index in a temporary location and swaps it in with an atomic
rename, so a running MCP server (and its open WAL) never observes a half-built
index. Deleting the .code-graph/ directory by hand skips that swap, which is
the exact situation the atomic path exists for.
get_index_status and rebuild_index do dispatch over JSON-RPC, but they are
deliberately kept out of tools/list to save tokens (src/mcp/tools.rs), so
they are not in your callable tool set — the CLI above is the surface you have.
It is also the only one that works with no server running.
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.

index is a skill published in the GitHub repository sdsrss/code-graph-mcp (84 stars, last pushed 2d ago), licensed MIT. It adds 44 tokens to every session and 263 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-14.

why
Work out whether a failure is your machine or your code before debugging either, using the environment this repository has declared and the dependency map. Use when a test, build or command fails and the cause is not obvious from the error.
frigg-first-code-search
Default to Frigg MCP instead of shell rg/grep/find/fd/cat/sed for source-code discovery, search, navigation, and proof reads in attached repos. Scenario-first routing: pick the flow, then the tool. Shell remains correct for git, build/test output, generated/unindexed paths, explicit live-disk checks, and when Frigg is…
dekko-verify
Sanity-check a suspiciously low or zero call-graph result from dekko (getcallers, getcallees, findusages, impactedtests, unused) before concluding "no callers" or "dead code," or a heritage/throws-provenance result (query supertypes, query subtypes, query throws) that labels something (external) when you expect it to…
dekko-refactor
List every site a rename, move, or signature change must touch before editing, then prove nothing was missed after. Trigger when about to rename a function, method, class or type, rename or move a file or module, change a parameter list or return type, move a symbol between files, or remove a symbol, in a repo with a…
dekko-debug
Work a stack trace, exception, or error report from dekko's map instead of reading each frame's file. Trigger when given a traceback, an exception type or message, a failing test's error, or a question like "why does X raise", "who handles this error", "how does control get from A to B", or "where is this env var…
gossiphs
Use when you need to find related files, understand code dependencies, or analyze impact scope. Triggers when the user asks about: "Which files use this function/class?" "What files will be affected if I change this?" "Find code related to X" "What does this file depend on?" "Where is this symbol defined/referenced?"…
