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 | $0.00026 | $0.01070 |
| Opus 5 | $0.00013 | $0.00535 |
| Sonnet 5 | $0.00005 | $0.00214 |
| Haiku 4.5 | $0.00003 | $0.00107 |
Grade A, and why
mathflow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Installed Root
Resolve the installed reasflow-dev skills root before running packaged scripts:
REASFLOW_SKILLS_ROOT="${REASFLOW_SKILLS_ROOT:-}"
if [ -z "$REASFLOW_SKILLS_ROOT" ]; then
if [ -d ./.agents/skills ]; then
REASFLOW_SKILLS_ROOT="$(pwd)/.agents/skills"
elif [ -d "$HOME/.agents/skills" ]; then
REASFLOW_SKILLS_ROOT="$HOME/.agents/skills"
else
echo "reasflow-dev skills not found in ./.agents/skills or $HOME/.agents/skills" >&2
exit 1

Role
mathflow is the only top-level skill for staged mathematical work. It is a router and state tracker, not a request to eagerly read every stage guide.
Use the skill tool only for mathflow; do not load stage files as top-level skills.
Use when
Use this skill for mathematical research, contest modeling, derivations, proof checks, numerical experiments, result validation, or final mathematical reporting when the work may need staged judgment.
Stage Files
Stage guidance lives in subordinate files under this skill directory:
stages/problem-analysis.mdstages/mathematical-modeling.mdstages/derivation-and-proof-checking.mdstages/research-planning.mdstages/numerical-experimentation.mdstages/result-validation.mdstages/self-audit-loop.mdstages/report-writing.md
When the next step requires detailed stage rules, read only the one relevant stage file. Do not read all stage files up front.
Mathflow State
Start each staged response with a compact state block:
Mathflow State
- Current stage: <stage name or "triage">
- Evidence so far: <one short sentence>
- Next stage: <one stage name or "fast path">
- Why this stage: <one short sentence>
- Needs from user: <missing input or "none">
For small tasks, use fast path and answer directly after the state block when a full stage handoff would add ceremony without reducing risk.
Routing Rules
- Start underspecified or open-ended work in
problem-analysis. - Use
mathematical-modelingbefore introducing new variables, equations, assumptions, or model families. - Use
derivation-and-proof-checkingwhen a claim depends on proof, derivation, symbolic manipulation, or mathematical argument quality. - Use
research-planningbefore simulations, solver runs, sweeps, empirical checks, or numerical comparisons. - Use
numerical-experimentationfor reproducible computational execution after an objective, baseline, metric, and stop rule exist. - Use
result-validationwhen a result needs special cases, limit cases, sensitivity, consistency, or counterexample checks. - Use
self-audit-looponly as the final adversarial review before strong conclusions or final reporting. - Use
report-writingonly when prior work has enough grounded material to write honestly.
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

mathflow is a skill published in the GitHub repository sillyDaibo/reasflow-dev (2 stars, last pushed 7d ago), licensed MIT. It adds 26 tokens to every session and 1,070 once invoked, about $0.0001 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.
