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 | $0.00055 | $0.00719 |
| Opus 5 | $0.00028 | $0.00360 |
| Sonnet 5 | $0.00011 | $0.00144 |
| Haiku 4.5 | $0.00006 | $0.00072 |
Grade A, and why
gitnexus-exploring 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 4d 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.
This is a copy
86% identical to gitnexus-exploring — 25 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Exploring Codebases with GitNexus
When to Use
- "How does authentication work?"
- "What's the project structure?"
- "Show me the main components"
- "Where is the database logic?"
- Understanding code you haven't seen before
Workflow
1. READ gitnexus://repos → Discover indexed repos
2. READ gitnexus://repo/{name}/context → Codebase overview, check staleness
3. gitnexus_query({query: "<what you want to understand>"}) → Find related execution flows
4. gitnexus_context({name: "<symbol>"}) → Deep dive on specific symbol
5. READ gitnexus://repo/{name}/process/{name} → Trace full execution flow
If step 2 says "Index is stale" → run
npx gitnexus analyzein terminal.
Checklist
- [ ] READ gitnexus://repo/{name}/context
- [ ] gitnexus_query for the concept you want to understand
- [ ] Review returned processes (execution flows)
- [ ] gitnexus_context on key symbols for callers/callees
- [ ] READ process resource for full execution traces
- [ ] Read source files for implementation details
Resources
| Resource | What you get |
|---|---|
gitnexus://repo/{name}/context |
Stats, staleness warning (~150 tokens) |

Tools
gitnexus_query — find execution flows related to a concept:
gitnexus_query({query: "payment processing"})
→ Processes: CheckoutFlow, RefundFlow, WebhookHandler
→ Symbols grouped by flow with file locations
gitnexus_context — 360-degree view of a symbol:
gitnexus_context({name: "validateUser"})
→ Incoming calls: loginHandler, apiMiddleware
→ Outgoing calls: checkToken, getUserById
→ Processes: LoginFlow (step 2/5), TokenRefresh (step 1/3)
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.

gitnexus-exploring is a skill published in the GitHub repository metagit-ai/metagit-cli (2 stars, last pushed 6d ago), licensed MIT. It adds 55 tokens to every session and 719 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 86% identical to gitnexus-exploring, differing in 25 lines, and is treated as a copy.

evm
Help users answer one question: "Are we on track?" using Earned Value Management metrics. This skill replaces gut-feel status reporting and traffic-light dashboards with four computed numbers (SV, SPI, CV, CPI) that tell you exactly where a project stands — in schedule and in budget — at any point in time.
content-cadence
Pipeline for turning one R&D artefact (PR, PoC, analysis) into one public post — briefing or deep dive — plus a social derivative where the overlay scopes one in. Triggers when an R&D output is ready to become content, or when drafting any blog post for the site. Enforces the anonymisation gate and repo editorial…
tco
Help users answer one question: "What will this actually cost?" using Total Cost of Ownership analysis. This skill replaces sticker-price comparisons with lifetime cost calculations that include maintenance, operations, time value of money, and residual value.
montecarlo
Help users answer one question: "What's the probability we finish by this date?" using Monte Carlo schedule simulation. This skill replaces single-point PERT estimates with full probability distributions over project duration.
pert
Help users produce defensible project estimates using PERT (Program Evaluation and Review Technique) with optional reality adjustments via insight tags. This skill replaces gut-feel single-point estimates with structured three-point estimation and confidence intervals.
