At a glance

Implement modern PHP error and exception handling patterns. An agent skill from HoangNguyen0403/agent-skills-standard.

  • Implementing exception hierarchies
  • SKILL.md covers Priority: P0 (CRITICAL), Structure, Build Exception Hierarchies and Configure Global Error Handling, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Custom exceptions in PHP

What it does

Php Error Handling is an agent skill from HoangNguyen0403/agent-skills-standard. Implement modern PHP error and exception handling patterns. Use when implementing exception hierarchies, error handlers, or custom exceptions in PHP.

Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/implementation.md`).

It sits in Development, covering Error handling. It works with PHP. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Implementing exception hierarchies
  • Custom exceptions in PHP

Example prompts

  • “/php-error-handling”

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. 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

Php Error Handling loads about 488 tokens when it runs, and up to ~844 if it reads all its reference files. Until then it costs about 42 tokens; SKILL.md has 159 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~488
With references · SKILL.md plus every file in references/, read only if the agent opens them
~844

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.

Implement modern PHP error and exception handling patterns. Use when implementing exception hierarchies, error handlers, or custom exceptions in PHP.

PHP Error Handling

Priority: P0 (CRITICAL)

Structure

See implementation examples for directory layout.

Build Exception Hierarchies

  • Exception-Driven: Favor throwing exceptions over returning false or null for error states.
  • Custom Exceptions: Extend RuntimeException or LogicException for domain-specific errors.
  • Multi-Catch: Use Union types in catch blocks: catch (DomainException | InvalidArgumentException $e).

See implementation examples for domain exception hierarchy with multi-catch and finally.

Configure Global Error Handling

  • Throwable Interface: Always catch Throwable for both PHP 7/8 Errors and Exceptions.
  • Global Handler: Use set_exception_handler and set_error_handler for top-level logging and cleanup.
  • Finally: Always use finally for resource cleanup (e.g., closing file handles, DB connections).
  • PSR-3 Logging: Implement Psr\Log\LoggerInterface for structured error reporting.
  • Production Guard: Ensure display_errors=Off and log_errors=On in production php.ini.

Anti-Patterns

  • No @ error suppression: Handle or log errors explicitly.
  • No empty catch blocks: Log or rethrow all caught exceptions.
  • No exceptions for control flow: Reserve for unexpected errors only.
  • No display_errors in production: Log to file; never show users.
