Jsf Ajax

What it does

When your agent uses it

• Working on AJAX updates
• P:commandButton update attributes
• PrimeFaces AJAX callbacks
• Partial page rendering

Example prompts

• “/jsf-ajax”

Workflow steps

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

1. 1AJAX UPDATE RULE: NEVER use plain HTML elements (div, span) with id attributes for AJAX updates - use JSF components (h:panelGroup…
2. 2RENDERED ATTRIBUTE RULE: NEVER use rendered on plain HTML elements - JSF ignores it; use h:panelGroup layout="block" instead
3. 3COMPONENT REFERENCES: Use p:resolveFirstComponentWithId for updates: update=":#{p:resolveFirstComponentWithId('componentId',view).clientId}"
4. 4NO CSS/jQuery SELECTORS: NEVER use @(.class), @(#id), @parent in update or process attributes. Use @this, @form, explicit IDs, or…

What it can do on your machine

Read from SKILL.md and the folder at commit d5d2020. 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 (its code samples are xhtml and java).

  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

Jsf Ajax loads about 1.3k tokens when it runs. Until then it costs about 112 tokens; SKILL.md has 388 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~112

When it runs · the whole SKILL.md, loaded when a task matches

~1.3k

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

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

JSF AJAX update rules for the HMIS project. Use when working on AJAX updates, p:commandButton update attributes, PrimeFaces AJAX callbacks, partial page rendering, or debugging AJAX update failures. Also covers JSF navigation patterns: why f:viewAction must not be used on @SessionScoped beans, and how initialization belongs in navigation methods. Critical rules to prevent silent AJAX failures and refresh/back-button state corruption.
