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.

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 | $0.00100 | $0.01482 |
| Opus 5.5 | $0.00040 | $0.00593 |
| Sonnet 5.5 | $0.00020 | $0.00296 |
| Haiku 4.5 | $0.00010 | $0.00148 |
Grade A, and why
ct-codebase-mapper 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codebase Mapper
Two instruments, used together:
cleo nexusis the symbol graph: callers, callees, blast radius, communities and execution flows, parsed from source. Use it for any question about how code connects.cleo mapis the project survey: stack, architecture, structure, conventions, testing, integrations and concerns. Use it for the one-page overview, and--storeto keep the findings in BRAIN.
1. Check the index before trusting it
cleo nexus status
Read nodeCount, lastIndexedAt and staleFileCount against fileCount.
Queries auto-refresh up to 25 stale files; beyond that they warn
W_NEXUS_INDEX_STALE. Refresh with cleo nexus analyze (incremental; --full
rebuilds). An empty or stale index gives confident-looking but incomplete
answers — say which you relied on.
assessment.referenceCount is how many static references the graph could not
resolve, so known callers are incomplete. Inspect them a page at a time:
cleo nexus status --references # per-kind counts + first 20
cleo nexus status --references --reference-kind unresolved --references-limit 500
cleo nexus status --references --references-offset <referencesPage.nextOffset>
referencesByKind counts the whole list; referencesPage holds one page
(max 5000). The full list is never returned in one call; it is named in
_withheld.references with its size.
Project-scoped queries use the declared portable project id. --project-id
may name that id or a recorded, unambiguous legacy alias; an alias warns
W_NEXUS_LEGACY_PROJECT_ID. A foreign or colliding id is refused: run the
query from the intended checkout. Moving a checkout retains its id and graph;
never derive a replacement id from the new path or re-analyze solely for a move.
2. Survey the project
cleo map # full survey
cleo map --focus concerns # one area: stack | architecture | structure |
# conventions | testing | integrations | concerns
cleo map --store # same survey, findings stored to BRAIN
# (tagged source: 'codebase-map')
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.

ct-codebase-mapper is a skill published in the GitHub repository kryptobaseddev/cleo (159 stars, last pushed yesterday), licensed MIT. It adds 100 tokens to every session and 1,482 once invoked, about $0.0004 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 2026-09-03.
