mike-params

mike-params is a skill for Claude Code, Codex from Zhonghao1995/Agentic-MIKE-Plus. It costs 86 tokens per session (668 once invoked), scanned A, original, MIT.

A tool for reading and changing settings in MIKE+, software used to build and simulate water and drainage networks. It works with model database tables such as pipes, nodes, and catchments.

In plain words
What is it for?
Use it to inspect or update pipe sizes, roughness, manhole levels, catchment properties, and other model settings before running a simulation.
Why use it?
It removes the need to edit MIKE+ model databases manually when a parameter must be checked or changed. It also reports the old and new values after an edit.

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.

Security

Grade A, and why

mike-params 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 6d 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 — 36 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MIKE+ Parameters

Reads and edits values in the MIKE+ model database tables (via mikeplus). This is the "edit the model" capability that sits between mike-model (overview) and mike-runner (execute).

Tools

  • mike_get_values{sqlite, table, columns?, muids?} → current values. Read-only. Use to identify a parameter before changing it.
  • mike_set_values{sqlite, table, values, muids | all} → applies the change and returns before/after for the affected rows. Mutates the database.

Common tables / columns

  • msm_Link — pipes/reaches: Diameter, Width, Height, Manning (Manning's M; higher = smoother), MaterialID, TypeNo.
  • msm_Node — manholes/nodes: GroundLevel, InvertLevel, Diameter.
  • msm_Catchment — catchments: area / imperviousness / runoff parameters.
  • msm_Project — simulation setups (used by mike_run's simulation).

Conventions (safety)

  • Always operate on a COPYmike_set_values writes to the database and mikeplus has no undo.
  • Scope every edit. Pass muids to target specific elements; only set all=true when you truly mean every row.
  • Confirm with the returned before/after (or a follow-up mike_get_values) before re-running.
  • Edit with the Base scenario active (or a scenario that shares Base's alternatives). Under a scenario with its own alternatives mikeplus cannot write and the tool errors "did not persist"; a variant for comparison is a second model COPY, not a scenario (see mike-compare).
  • Boundary/rain changes: the rainfall boundary is msm_BBoundary (TypeNo = 1; TSConnection = dfs0 path relative to the model folder, TimeseriesName = dfs0 item) — see mike-rain.
  • After editing, re-run with mike_run and quantify the effect with mike_results_compare (mike-compare).

Orchestration (identify -> change -> re-run -> compare)

mike_model_info / mike_get_values   -> identify current parameter
mike_set_values                     -> change it (on the variant copy)  -> before/after
mike_run                            -> new .res1d
mike_results_compare / mike_plot_compare -> against the baseline run

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.

mike-params is a skill published in the GitHub repository Zhonghao1995/Agentic-MIKE-Plus (7 stars, last pushed 21d ago), licensed MIT. It adds 86 tokens to every session and 668 once invoked, about $0.0004 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.
