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.
npx agentmods add instructions/diomonogatari/stash-mcp/codebasegit clone --depth 1 https://github.com/diomonogatari/stash-mcpWhat 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 | $0.00600 | $0.00600 |
| Opus 5 | $0.00300 | $0.00300 |
| Sonnet 5 | $0.00120 | $0.00120 |
| Haiku 4.5 | $0.00060 | $0.00060 |
Grade A, and why
stash-mcp codebase.instructions.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 yesterday.
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 — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stash MCP Server — Codebase Overview
What This Project Is
Stash MCP Server is a .NET 10.0 Model Context Protocol (MCP) server for Atlassian Bitbucket Server (Stash). It exposes tools that let AI assistants interact with repositories, pull requests, code reviews, builds, and search.

Git Submodule — Bitbucket.Net
The Bitbucket REST API client lives in lib/Bitbucket.Net/ as a git submodule pointing to https://github.com/diomonogatari/Bitbucket.Net.git. We own both repositories.
Key rules
- StashMcpServer references Bitbucket.Net via ProjectReference, not NuGet:
<ProjectReference Include="..\..\lib\Bitbucket.Net\src\Bitbucket.Net\Bitbucket.Net.csproj" /> - Bitbucket.Net manages its own package versions. It has a
Directory.Packages.propsthat opts out of CPM (ManagePackageVersionsCentrally=false), so stash-mcp's CPM does not conflict. - Never add Bitbucket.Net packages to stash-mcp's
Directory.Packages.props. Bitbucket.Net's dependencies (e.g., Flurl.Http) are declared in its own.csproj. - Cloning requires
--recurse-submodules:git clone --recurse-submodules https://github.com/diomonogatari/stash-mcp.git # or, after a plain clone: git submodule update --init --recursive - CI workflows use
submodules: recursiveon allactions/checkout@v4steps. - Dockerfile copies submodule source in the build stage — both the
.csproj(for restore layer caching) and the full source.
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.

stash-mcp codebase.instructions.md is an instructions file published in the GitHub repository diomonogatari/stash-mcp (4 stars, last pushed 2mo ago), licensed MIT. It adds 600 tokens to every session, about $0.0030 per session on Opus 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 2026-08-31.
