What it does

Symbol Table Builder is an agent skill from zhnnky329/MathModeling-skills. Build and maintain one global mathematical symbol and unit table from the problem frame and active method cards, resolving cross-subquestion conflicts before code or paper work.

Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: 面向数学建模竞赛的 Claude Code / Codex Skills ，支持分阶段建模流程与 Python、MATLAB/北太天元代码分支。 The licence is MIT.

Example prompts

  • “/symbol-table-builder”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Extract inputs, outputs, parameters, decisions, states, indices, sets, functions, and intermediate quantities.
  2. Preserve user-established notation unless it conflicts or is ambiguous.
  3. Resolve
  4. Classify each symbol by role and scope.
  5. Save or update planning/symbol_table.md.
  6. If a canonical symbol changes, classify it CANONICAL and run scoped consistency for affected Qx.

What it can do on your machine

Read from SKILL.md and the folder at commit 0b46e9c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Symbol Table Builder loads about 475 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 211 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~475

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Build and maintain one global mathematical symbol and unit table from the problem frame and active method cards, resolving cross-subquestion conflicts before code or paper work.

Purpose

Ensure the same concept uses one symbol and different concepts do not collide.

Inputs

  • problem parse and relationships;
  • active methods/Qx/qx_method_card.md;
  • approved code plans when available;
  • question dependency map;
  • existing planning/symbol_table.md.

Read legacy candidate pools only when method cards are absent.

Workflow

  1. Extract inputs, outputs, parameters, decisions, states, indices, sets, functions, and intermediate quantities.
  2. Preserve user-established notation unless it conflicts or is ambiguous.
  3. Resolve:
    • same meaning with different symbols;
    • different meanings with the same symbol;
    • unit/domain conflicts;
    • Qx output-to-input handoff conflicts.
  4. Classify each symbol by role and scope.
  5. Save or update planning/symbol_table.md.
  6. If a canonical symbol changes, classify it CANONICAL and run scoped consistency for affected Qx.

Table Fields

  • symbol;
  • plain name;
  • definition;
  • type: input, output, parameter, estimated parameter, decision, state, intermediate, index, set, function;
  • domain/range;
  • unit;
  • scope/Qx;
  • source artifact;
  • notes or conflict resolution.

Rules

  • Define every symbol before first use.
  • Record units and domains when applicable.
  • Use one notation for cross-question handoffs.
  • Do not invent variables to make a table look complete.
  • Do not maintain a separate verbose conflict log; record material resolutions in the table notes.

Verification

  • Active method-card and code-plan variables are covered.
  • No unresolved symbol or unit collision remains.
  • Shared quantities agree across Qx.
  • Downstream artifacts can cite one canonical table.
