+Read [the consumer skill](resources/skills/fast-forward-http/SKILL.md) when changing application integration
+examples, consumer guides or the skill. Keep its version contract, references
+and executable examples aligned with the supported public API. The canonical
+distributable source is `resources/skills`; it needs no installed copy or host
+alias. Repository maintenance continues to follow this AGENTS.md.

+description: Wire Fast Forward HTTP providers into an application container and obtain PSR-17 factories and a PSR-18 client.
+license: MIT; see LICENSE
+compatibility: Supports fast-forward/http ^1.2 and PHP ^8.3. Requires Composer and declared extensions; inspect the installed version. Earlier releases are outside this contract.
+metadata:
+  author: Fast Forward
+  api-baseline: fast-forward/http ^1.2

+
+# Compose HTTP services
+
+Use this skill for an application consuming `fast-forward/http:^1.2`.
+Read its instructions, manifest/lockfile and installed source before editing.
+Run `composer show fast-forward/http`. For versions outside this contract,
+inspect matching documentation; do not silently upgrade the application.
+
+## First working integration
+
+Requires PHP ^8.3, Composer's application autoloader and this package's runtime
+dependencies.
+With authority to install the dependency:
+
+```sh
+composer require 'fast-forward/http:^1.2'
+```
+
+Create `app.php` in the application root alongside composer.json/vendor:
+
+```php
+<?php
+
+declare(strict_types=1);
+
+require __DIR__ . '/vendor/autoload.php';
+
+use FastForward\Config\ArrayConfig;
+use FastForward\Container\ContainerInterface;
+use FastForward\Http\ServiceProvider\HttpServiceProvider;
+use Psr\Http\Client\ClientInterface;
+use Psr\Http\Message\ResponseFactoryInterface;
+use Psr\Http\Message\RequestFactoryInterface;
+use function FastForward\Container\container;
+
+$config = new ArrayConfig([ContainerInterface::class => [HttpServiceProvider::class]]);
+$container = container($config);
+$response = $container->get(ResponseFactoryInterface::class)->createResponse(202);
+$request = $container->get(RequestFactoryInterface::class)->createRequest('GET', 'https://example.invalid/');
+$client = $container->get(ClientInterface::class);
+if ($response->getStatusCode() !== 202 || $request->getMethod() !== 'GET' || !$client instanceof ClientInterface) {
+    throw new RuntimeException('HTTP composition failed.');
+}
+
+echo "integration ready\n";
+```
+
+Run `php app.php`. It throws on a wrong result; success prints
+`integration ready`. It uses no production data and starts no server.
+
+## Wiring and failure boundaries
+
+Store the raw provider list under `FastForward\Container\ContainerInterface::class`; the ConfigContainer exposes this as `config.FastForward\Container\ContainerInterface`. Pass the configuration to `container($config)`, then pass the returned container to the application's runtime. The provider composes HttpMessageFactoryServiceProvider and HttpClientServiceProvider. It supplies client/factories and a globals-based server request, not an HTTP server, route dispatcher or response emitter.
+
+Without application configuration use `container(HttpServiceProvider::class)`. Resolve the extended `FastForward\Http\Message\Factory\ResponseFactoryInterface` for payload helpers, and the PSR ResponseFactoryInterface for ordinary PSR-17 creation. They are distinct services.
+
+Put a custom ArrayServiceProvider before defaults to override an interface. The first source that successfully resolves the id wins; service-provider products are cached. Request/response factory calls create message objects, while resolving the globals-based ServerRequestInterface service can cache the request: build a fresh request explicitly for long-lived worker iterations. Missing services raise PSR-11 not-found errors; non-PSR factory failures propagate. Do not send the example.invalid request; it tests composition without a network dependency.
+
+The helper tries aggregate sources in registration order. A PSR container or
+not-found exception from one source permits fallback to another source; other
+throwables propagate. Source priority is therefore the first successful resolution,
+not a guarantee that an earlier broken factory terminates lookup. Nested provider
+list errors during helper composition are caught; if services are absent, inspect
+the raw configuration and resolve the provider directly to diagnose the failure.
+
+## Verify integration
+
+Run the [complete example](examples/integration.php) against the application's
+autoloader in a disposable process. It checks success and negative cases:
+
+```sh
+php /path/to/fast-forward-http/examples/integration.php ./vendor/autoload.php
+```
+
+Expected final marker: `fast-forward-http: ok`. Keep application-specific regression
+tests in its existing PHPUnit suite, with each fixture class in its same-named
+file. File copying, host discovery and completed agent tasks are different checks.
+For optional copying/synchronization load
+[installation and lifecycle](references/installation.md).

+# Optional installation of fast-forward-http
+
+`fast-forward/http:^1.2` includes this complete package under
+`resources/skills/fast-forward-http`. Run `composer show fast-forward/http`
+and inspect that path before copying. Earlier releases are outside this skill
+contract. Composer suggestions do not install anything automatically. Library
+installation, discovery-root copies and session activation are separate steps.
+
+## Team project with llm/skills
+
+Use Composer 2 and optionally add `llm/skills:^1.15` as development tooling.
+Start with a project target for reviewable team configuration. Preserve existing
+settings/aliases/approvals when merging these keys into `skills.json` **before**
+installing or enabling the plugin:
+
+```json
+{
+  "target": ".agents/skills",
+  "aliases": [],
+  "discovery": false,
+  "auto-sync": true,
+  "vendor-sources": false,
+  "dependencies": {
+    "composer": {
+      "trusted": ["fast-forward/http"],
+      "trusted-replace": true
+    }
+  }
+}
+```
+
+This replaces implicit dependency trust with a narrow donor allowlist, disables
+remote vendor sources and requests no host aliases. A deliberate
+`fast-forward/*` allowlist grants broader organizational trust. Use the actual
+host's project discovery root; Claude Code can choose `.claude/skills`.
+Do not erase intentional aliases or other donors in an existing manifest.
+
+If the application owner has authorized this plugin's execution, merge its
+root approval, install it and inspect the report:
+
+```sh
+composer config allow-plugins.llm/skills true
+composer require --dev 'llm/skills:^1.15'
+composer skills:show
+```
+
+The donor only suggests the tool; it neither requires it at runtime nor grants
+this approval on behalf of consumers. Commit the chosen manifest, skills.json,
+application lockfile and intended project copies according to project policy.
+Approved Composer install/update operations then perform automatic sync.
+
+For manual timing, choose `auto-sync:false` before installation and use:
+
+```sh
+composer skills:show
+composer skills:update fast-forward/http --dry-run
+composer skills:update fast-forward/http
+```
+
+Explicitly naming a donor selects/trusts it for that run. Test automatic trust
+without a package argument when that policy is what matters. With Composer
+2.10.3 and llm/skills 1.15.0, `--no-scripts` alone still permits automatic copy;
+`auto-sync:false` disables automatic sync and `--no-plugins` stops plugin loading.
+Verify these behaviors again after changing tool versions.
+
+## Update and removal boundaries
+
+A 1.15 sync overwrites incoming same-path files. It retains extra local files
+and files removed from the donor's next version. Removing a donor or uninstalling
+the plugin does not delete its existing instruction copies. Regard the copy as
+donor-owned; keep deliberate local instructions in a separate skill name.
+Record the installed donor/tool versions and review diffs before each refresh.
+
+Inspect cleanup without applying it:
+
+```sh
+composer skills:update --clean --dry-run
+```
+
+An unscoped clean can remove all target skills, including handwritten ones.
+Scoped clean reinstalls the current selection; it cannot locate an absent donor
+by historical ownership. Inventory affected directories, back up outside
+discovery, and obtain authority before any destructive cleanup. Do not add a
+root-wide clean hook.
+
+## Guarded manual copying
+
+Choose the existing project root, then copy all files together:
+
+```sh
+skill_source="vendor/fast-forward/http/resources/skills/fast-forward-http"
+skill_target=".agents/skills/fast-forward-http"
+test -f "$skill_source/SKILL.md" &&
+test ! -e "$skill_target" &&
+test ! -L "$skill_target" &&
+mkdir -p "$(dirname "$skill_target")" &&
+cp -R "$skill_source" "$skill_target"
+```
+
+Both existing directories and dangling links are refused. Global use is an
+explicit alternative: set skill_target to
+`$HOME/.agents/skills/fast-forward-http` for Codex or the configured
+`$HOME/.claude/skills/fast-forward-http` for Claude Code.
+Do not create a symlink into replaceable vendor content. A globally installed
+Composer plugin does not constitute a global instruction copy.
+
+For a selected manual update/removal, first move only that package into a unique
+backup outside discovery:
+
+```sh
+skill_backup="$HOME/.agent-skill-backups/fast-forward-http-$(date +%Y%m%d%H%M%S)-$$"
+test -d "$skill_target" &&
+test ! -L "$skill_target" &&
+test ! -e "$skill_backup" &&
+test ! -L "$skill_backup" &&
+mkdir -p "$(dirname "$skill_backup")" &&
+mv "$skill_target" "$skill_backup"
+```
+
+For an update review the new source, then repeat the guarded copy. To roll back,
+archive any replacement and restore the saved whole directory to the same
+target. A manager-owned copy may return on its next sync until the consumer
+changes that donor's trust/dependency configuration. Keep backups out of every
+discovery directory.
+
+## Optional Skills CLI
+
+Requires npm, Node.js 22.20.0+ and Git for repository sources. The reviewed pin
+is skills@1.7.2; evaluate version changes separately. Choose only the actual host:
+
+```sh
+npx --yes skills@1.7.2 add ./vendor/fast-forward/http/resources/skills/fast-forward-http --skill fast-forward-http --agent codex --copy --yes
+npx --yes skills@1.7.2 list --agent codex
+```
+
+Use `--agent claude-code` for that host. Add `--global` to both commands only
+when global scope was selected. Preserve/commit intended project copies and the
+CLI's project lockfile. For a remote source first set SKILL_REF to a reviewed
+immutable commit:
+
+```sh
+npx --yes skills@1.7.2 add "https://github.com/php-fast-forward/http/tree/$SKILL_REF/resources/skills/fast-forward-http" --skill fast-forward-http --agent codex --copy --yes
+```
+
+Review the new revision and back up local edits before repeating for an update.
+Remove the chosen package/scope with:
+
+```sh
+npx --yes skills@1.7.2 remove fast-forward-http --agent codex --yes
+# Only for a selected global copy:
+npx --yes skills@1.7.2 remove fast-forward-http --agent codex --global --yes
+```
+
+After every route inspect the complete files, refresh the agent session,
+confirm the public name is discovered and perform a bounded consumer task.
+A copy, listing and successful task are separate observations.
+
+Tool contracts: [llm/skills 1.15.0](https://github.com/roxblnfk/skills/tree/1.15.0),
+[Composer plugin approval](https://getcomposer.org/doc/06-config.md#allow-plugins)
+and [Skills CLI](https://github.com/vercel-labs/skills).
+
+The Skills CLI 1.7.2 removal report is not proof that the canonical project
+`.agents/skills` directory disappeared. A Codex project exercise reported one
+removal while that copied package remained. Inspect the actual target and CLI
+lockfiles afterwards. If an obsolete copy remains, verify that no other host
+uses it, then archive only that selected directory outside discovery using the
+manual recovery procedure above. Do not run a blanket clean to compensate.
