ai-mind: Skill for Claude Code

.agents/skills/speckit-agent-context-update/SKILL.md

speckit-agent-context-update is a skill for Claude Code, Codex from HWYD/ai-mind. It costs 20 tokens per session (409 once invoked), scanned A, original, MIT.

A command that refreshes the managed Spec Kit section in one or more coding-agent instruction files. Spec Kit is a project convention for keeping feature plans and related guidance in a predictable place.

In plain words
What is it for?
It helps update files such as AGENTS.md, CLAUDE.md, or Copilot instructions after a Spec Kit plan changes.
Why use it?
It keeps the instruction file pointing to the latest discovered plan without manually editing the managed section. It also respects the project’s configured file paths and markers.

Written for no agent in particular: nothing here depends on one. Also seen: mentions CLAUDE.md; installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is HWYD/ai-mind's own configuration. It tells Claude Code and Codex how to work on ai-mind itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-mind configures →

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

speckit-agent-context-update 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 2mo 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.

What it actually says

Update Coding Agent Context

Refresh the managed Spec Kit section inside the active coding agent's context/instruction file (e.g. CLAUDE.md, .github/copilot-instructions.md, AGENTS.md).

Behavior

The script reads the agent-context extension config at .specify/extensions/agent-context/agent-context-config.yml to discover:

  • context_file — the path of the coding agent context file to manage.
  • context_files — optional project-relative paths for multiple coding agent context files. When non-empty, the script updates each listed file and the list takes precedence over context_file.
  • context_markers.start / .end — the delimiters surrounding the managed section. Defaults to <!-- SPECKIT START --> and <!-- SPECKIT END --> when the field is missing.

It then creates, replaces, or appends the managed block so that the section points at the most recent plan path when one can be discovered (specs/<feature>/plan.md).

If context_files and context_file are empty, the command reports nothing to do and exits successfully. Context file paths must stay project-relative; absolute paths, Windows drive paths, backslash separators, and .. path segments are rejected.

Execution

  • Bash: .specify/extensions/agent-context/scripts/bash/update-agent-context.sh [plan_path]
  • PowerShell: .specify/extensions/agent-context/scripts/powershell/update-agent-context.ps1 [plan_path]

When plan_path is omitted, the script auto-detects the most recently modified specs/*/plan.md.

Changes

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.
