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 | $0.00154 | $0.01036 |
| Opus 5 | $0.00077 | $0.00518 |
| Sonnet 5 | $0.00031 | $0.00207 |
| Haiku 4.5 | $0.00015 | $0.00104 |
Grade A, and why
ras-results 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 — 37 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Tools
| Tool | Does |
|---|---|
ras_results_summary(hdf, top_n?) |
plan info, run_qa, unsteady summary, volume accounting, runtime, units_system + units, cross_sections (n, reaches, upstream / downstream, top_by_max_flow with max WSE / velocity / time), mesh_areas (n_cells, n_wet_cells, max_ws_max, max_depth + cell + time), reference_lines / reference_points / boundary_conditions peaks |
ras_results_timeseries(hdf, kind?, location?, variable?, mesh?, max_points?) |
one series + peak, peak_time, min, mean, dt_seconds; kind = xsec (default; location 'River/Reach/Station' or the station; variable flow / water_surface / velocity / velocity_channel / flow_lateral), ref_line, ref_point, boundary (location = name; variable e.g. Flow, Water Surface), mesh_cell (mesh + location = cell id) |
ras_results_compare(hdf_a, hdf_b, kind?, location?, variable?, mesh?, top_n?) |
at one location: delta_peak (+ %), peak_time_shift_min, rmse, nse_b_vs_a, flows also delta_volume; xsec with NO location: ranked (n increased / decreased / unchanged, top-N by change) + largest_change |
| `ras_plot(plot, hdf | hdfs, labels?, out_png, kind?, location?, variable?, mesh?, reach?, title?)` |
Procedure
ras_results_summary(hdf)first: confirmrun_qa.statusis usable, learn the units, the cross-section labels (upstream/downstream/top_by_max_flow[].label), mesh names, reference line names.- Numbers:

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.

ras-results is a skill published in the GitHub repository Zhonghao1995/Agentic-HEC-RAS (1 stars, last pushed 24d ago), licensed MIT. It adds 154 tokens to every session and 1,036 once invoked, about $0.0008 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.

mike-end-to-end
Standard operating procedure for an auditable, headless MIKE+ workflow via the mike-plus MCP server — how to plan, copy, run, QA-gate, compare, plot, audit, and safely stop. Use FIRST whenever an agent is handed a MIKE+ model (.sqlite) or result (.res1d) plus a plain-language goal; it picks the operating mode and…
mike-compare
Compare two MIKE+ runs via the mike-plus MCP server — baseline vs scenario, before vs after a parameter edit — to say WHERE a change mattered and BY HOW MUCH (delta peak, delta volume, timing shift, RMSE/NSE) and to draw the overlay hydrograph. Use whenever two .res1d files of the same model exist or a re-run just…
mike-plot
Produce publication-style figures from MIKE+ .res1d results via the mike-plus MCP server — a stacked rainfall-runoff hydrograph, a single time series, a network map, a baseline-vs-scenario overlay, or a longitudinal profile (bed / crown / ground / max water level along a pipe string), in the house style (Arial 12…
mike-results
Read MIKE+ .res1d results via the mike-plus MCP server — list contents, summarize peaks, extract a single time series, or check which nodes flood (peak water level vs ground level). Use when an agent needs to inspect or pull numbers from MIKE+ network results (node water levels, link/reach discharge, velocities…
mike-audit
Record provenance for an Agentic MIKE+ step via the mike-plus MCP server — a manifest.json tying the model copy, inputs, edits, run QA status, result files and figures together, each file with a sha256. Use at the end of every run/compare/plot task (successful or failed) so the work can be audited, re-compared or…
mike-import
Bring an EPA SWMM (.inp) or EPANET (.inp) model into MIKE+ via the mike-plus MCP server — the bridge from an INP builder such as SWMMCanada or agentic-swmm into a MIKE+ database that mikemodelinfo / mikerun can use. Use when the user has an .inp and wants it in MIKE+. Requires MIKE+ installed + a checked-out license…
