update-spec

update-spec is a command for Claude Code from mistydew/tokenicode-deepseek-alpha. It costs 0 tokens per session (2,416 once invoked), scanned A, original, Apache-2.0.

A command for recording important implementation knowledge as code specifications: concrete rules about commands, APIs, databases, settings, validation, errors, and tests.

In plain words
What is it for?
Use it after finishing work, fixing a bug, or finding a new pattern, especially when changing APIs, database structure, infrastructure, or settings.
Why use it?
It keeps valuable discoveries from being lost and makes cross-part system behavior easier to implement and verify later.

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

update-spec 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 4d 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.

Update Code-Spec - Capture Executable Contracts

When you learn something valuable (from debugging, implementing, or discussion), use this command to update the relevant code-spec documents.

Timing: After completing a task, fixing a bug, or discovering a new pattern


Code-Spec First Rule (CRITICAL)

In this project, "spec" for implementation work means code-spec:

  • Executable contracts (not principle-only text)
  • Concrete signatures, payload fields, env keys, and boundary behavior
  • Testable validation/error behavior

If the change touches infra or cross-layer contracts, code-spec depth is mandatory.

Mandatory Triggers

Apply code-spec depth when the change includes any of:

  • New/changed command or API signature
  • Cross-layer request/response contract change
  • Database schema/migration change
  • Infra integration (storage, queue, cache, secrets, env wiring)

Mandatory Output (7 Sections)

For triggered tasks, include all sections below:

  1. Scope / Trigger
  2. Signatures (command/API/DB)
  3. Contracts (request/response/env)
  4. Validation & Error Matrix
  5. Good/Base/Bad Cases
  6. Tests Required (with assertion points)
  7. Wrong vs Correct (at least one pair)

When to Update Code-Specs

Trigger Example Target Spec
Implemented a feature Added template download with giget Relevant backend/ or frontend/ file
Made a design decision Used type field + mapping table for extensibility Relevant code-spec + "Design Decisions" section
Fixed a bug Found a subtle issue with error handling backend/error-handling.md
Discovered a pattern Found a better way to structure code Relevant backend/ or frontend/ file
Hit a gotcha Learned that X must be done before Y Relevant code-spec + "Common Mistakes" section
Established a convention Team agreed on naming pattern quality-guidelines.md
New thinking trigger "Don't forget to check X before doing Y" guides/*.md (as a checklist item, not detailed rules)

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.
